VS 2008 Adding Controls To A TableLayoutPanel?

Aug 31, 2009

When I add a control to a TLP in design mode several new properties get added to the control, such as ColumnSpan, RowSpan, etc, which can then be set in the properties window. If I add a control to a TLP in code these properties don't seem to be available. how to set these properties in code if it's even possible?

Add Controls To A TableLayoutPanel?

Mar 26, 2009

I want to create a 2-high, 6-wide grid with labels in the top row and text boxes in the bottom row. Creating the six labels and the six text boxes is easy. Main Question: How do I stuff them into the TableLayoutPanel at the locations I want?I assume that I write the labels as I would any other label, and read and write the text boxes as I would any other text box.Secondary question: Why do all Microsoft's examples do stuff I never need to do, and never do the simple stuff I need to do?

TableLayoutPanel/Button Controls Being Very Odd?

Jul 17, 2009

I have a class here that is misbehaving, and I can't understand why.Basically, when resizing to make this Form smaller, the buttons begin to extend outside of the TableLayoutPanel that contains them. This is not ideal.This is not an issue about resizing, my project does not allow resizing the main form, the problem occurs on my form before any resizing takes place; I simply demonstrate that the problem gets worse when resizing here as additional information.

C# - TableLayoutPanel GetControlFromPosition Does Not Get Non-visible Controls?

Aug 22, 2011

I'm using a TableLayoutPanel and I want to get the control at a specific position in the TableLayoutPanel. I want to iterate over the rows and columns of TableLayoutPanel but this question applies equally if I just wanted a single control at a specific row and column.Unfortunately GetControlFromPosition(int column, int row) only retrieves controls that are visible (that is their Visible property is set to True). This is no good to me as sometimes I want to access a control at a specific position that is not visible and then make it visible.

I have had to resort to iterating over the TableLayoutPanel.Controls collection, and then get the position of each control using GetPositionFromControl(Control control) or GetCellPosition(Control control) until I find the position I want.(I'm not sure of the difference between GetPositionFromControl and GetCellPosition methods as MS documentation is meagre, but I'll ask that question separately).

Dynamically Displaying Some Controls In A TableLayoutPanel?

Feb 17, 2012

I am dynamically displaying some controls in a TableLayoutPanel. The problem I'm faced with is that I want the controls to be displayed in a specific order, instead of just filling the TableLayoutPanel from 0,0 till the end of the panel.

I have 5 columns and 5 rows.

1st row is for buttons only, 2nd row for combobox, 3rd row for radio button.

I want it to be displayed like this:

Loop Through Controls In A Specific Row/column Location In A TableLayoutPanel

Aug 14, 2009

I have a bunch of controls loaded into the same row/column in a TableLayoutPanel. I only have one at controls visible property set to TRUE at a given time. I want to be able to loop through the controls that specific row/column position in the TableLayoutPanel and test for a condition (control type) and then set this control's property to TRUE and all others to FALSE. Bascially I am turning controls on/off.

I know can loop through an entire TableLayoutPanel like this:

For each control in TableLAyoutPanel.Controls
Next

How do I restrict this loop to a specific row/column in the TableLayoutPAnel? Can you qualify where specifically you want to look in the container control?

When In The Process Of Adding A Control To A TableLayoutPanel Do New ColumnStyles/RowStyles Get Added

Jul 30, 2009

I'm adding controls to a TableLayoutPanel in the form myTableLayoutPanel.Controls.Add(someControl, 5, 5), inserting the control in column 5, row 5. After that line of code has executed, I expect that the ColumnStyles and RowStyles properties of myTableLayoutPanel will contain ColumStyles for columns 0 through 5, and RowStyles for rows 0 through 5. This is not the case. where and when RowStyles and ColumnStyles are added to these properties and the best way to deal with adding styles when inserting new Controls?

VS 2008 Adding Controls From A Thread?

Mar 23, 2009

I'm trying to dynamically add a control to a form from an event that is raised from an asynchronious socket's thread.

In other words, when I get an OnDataArrival event is raised from the socket thread, I raise DataArrival event in my form. The form's DataArrival sub then tries to create and parent a control.

Whenever I try this, I get the following error: Controls created in one thread cannot be parented to a control in a different thread.I know a bit about delegates and invoking, and I think that's how to solve this problem, but I don't know where to declare the delegates and how to use them.

Ideally, I want a delegate/invoker to handle the DataArrival sub in the socket class so that everything that happens after that will be thread safe. Can this be done?

VS 2008 Adding Multiple User Controls To A Form?

Nov 10, 2010

I have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...

My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.

I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.

Dim pccard As New PC_Card
Dim x As Integer
Dim name As String

VS 2008 Dynamically Creating And Adding Dropdown Controls To DevExpress XtraGrid?

May 6, 2011

I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements

this is what the code looks like:

vb.net
Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit
For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1
column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp

[code]....

The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.

VS 2008 Autosize Tablelayoutpanel With Textboxes?

Oct 28, 2009

I have datagridview with some columns that the user can hide or show using a contextmenu. Below that I have some textboxes inside a tablelayoutpanel which the user can write into to filter the data in the datagridview.

But if the user hides a column in the datagridview, I want the textbox below to disappear as well and the other textboxes automatically take up the empty space.

I made some screenshots so you will be able to understand it better:

When the user hides the column:

The column named "Totaal prijs" has now gone and so has the corresponding textbox below. But the columns in the datagridview now stretch nicely to take up the free space. How can I do the same with the textboxes?

VS 2008 Dynamic Generation Of TableLayoutPanel

Mar 19, 2009

I have a container with different controls in it. This container can be shown 1 or more timeson a form. The number of times is not known when the application is build.So form with the number of containers must be generated by code. When the number of containers is high a scroll bar must be shown.My idea was to use the control TableLayoutPanel. The first row consists of the container with it's controls. When loading the form a number is calculated. This number is used to show the number of containers.

Adding Controls To A Panel?

Jan 19, 2009

I am trying to add controls to a Panel in a loop, but for some reason they are being added from the bottom up instead of top down.In a little test program I am running this

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
For i As Integer = 1 To 10[code]....

And this is the result I get ... the controls are added starting at the bottom. I need them to start at the top of the panel, with each new control being added under the previous one. If I remove the Dock statement, then the controls just get added on top of each other.

Adding Controls.....What Am I Doing Wrong?

Feb 5, 2010

I am converting a VBA program to VB. I need to create controls at runtime as I don't want the user to be limited to the amount of information that they can input. I am converting this statement in vba:




Dim CF As CashFlowControl


CF = New CashFlowControl

CF.Cashflow = Form1.Controls.Add("Forms.Textbox.1", "Cashflow" & Cashflows.Count + 1, True)
With CF.Cashflow
.Left = Form1.Label2.Left
.Width = Form1.Label2.Width
.Top = Form1.Label2.Top + Form1.Label2.Height + (Form1.Label2.Height * Cashflows.Count) + 5
.Visible = True
.Text = 0
.Text = Format(CF.Cashflow.Text, "$#,##0.00")
End With
I have tried:




Dim txtbox As New TextBox

CF.CashFlow = Form1.Controls.Add(txtbox)
With CF.CashFlow
.Name = "CashFlow" & Cashflows.Count + 1
.Left = Form1.Label2.Left
.Width = Form1.Label2.Width
.Top = Form1.Label2.Top + Form1.Label2.Height + (Form1.Label2.Height * Cashflows.Count) + 5
.Height = Form1.Label2.Height
.Visible = True
End With
I've also tried:





CF.CashFlow = Form1.Controls.Add("vbtextbox","Cashflow" & Cashflows.count + 1)
With CF.CashFlow
.Left = Form1.Label2.Left
.Width = Form1.Label2.Width
.Top = Form1.Label2.Top + Form1.Label2.Height + (Form1.Label2.Height * Cashflows.Count) + 5
.Height = Form1.Label2.Height
.Visible = True
End With
I still get the little wavy underline under the text after the "Form1.Controls.Add" statement and the error says "Value of Type 'string' cannot be converted to 'system.windows.forms.control." I also get the error "Too many arguments to 'Public Overridable Sub Add(value as systems.windows.forms.control)"

What am I missing here? This seems to be the way it is done in all of the examples that I have found on this site.

IDE :: Adding Controls At Runtime / Where Goes App?

May 18, 2009

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.

I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?

Adding And Deleting Controls Via Code?

Aug 14, 2011

I am trying to create and remove a series of controls programatically. The user will have a numeric updown to pick a number. The program will then create a bunch of duplicate controls based on whatever number they pick on the fly.

Public Class Form1
Private Sub NumericUpDown1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles numberDebts.ValueChanged[code].....

The creation part works just fine.As the number is toggled upward a new label is created.However whenever I remove labels it acts very strangely.The first time I bring it down it works just fine. Then the next 3 do nothing but the 4th removes another line.I can also toggle back and forth and it will eventually remove the label. So for example.

Starts with 1 selected - 1 label visible (1)
Change to 2 - 2 labels visible (1-2)
Change to 3 - 3 labels visible (1-3)[code]....

If I toggle back and forth between 2 and 3 eventually label 4 will go away.I want only 1- my numeric up down value to be displayed and have everything else after that removed.
