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 am creating TableLayoutpanel dynamically and placing labels in each cell..and i given label Dock Property Fill. all or ok But TableLayoutpanel Right side Border and Bottom Side border not displaying properly.
In my application i need to resize the TableLayoutpanel dynamically..when i resize this control automatically resize rows and columns equal size. I wrote below code it's working but it's working very slow.
Private Sub tbpanel_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Try Dim iColCount As Integer = tbpanel.ColumnCount
I need to resize Rows and columns dynamically in TableLayoutpanel..I achive this but it's not perfectly come in some times.. My requirement is how we are resize the rows and columns of TableLayoutpanel at design time..Same like i need to implement at Runtime.If i resize any row or column only That perticuler item only resizing ..
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?
For a winForm I'm building, I'm working with a TableLayoutPanel which has an arbitrary number of Textboxes and two buttons to add or remove boxes, + and -. The + and - buttons appear directly below the Textbox to which the user has given focus like so:
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.
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).
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?
i want insert a text into tablelayoutpanel cells..present i am inserting with the help of labels i am placing into cells..but it takes more time..so i decided to any other way to do this one.
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?
I'm programatically creating labels in programatically-created panels, and have run into an issue--the label's information isn't completely showing! COnsistently only the first few characters are consistently displayed. I've tried bringtofront, but it doesn't work at all. And the characters stop well short of the panel barrier--does anyone know what to do about this? I used messagebox.show(labelname.text) to make sure it wasn't working properly, and sure enough all the characters I want are in the label, but aren't appearing.
I'm calling a webservice that is returning an unknown quantity of images in the form of an a collection of byte arrays. (I can't change this) I need to display each image on a single aspx webpage. I'm currently using the Microsoft.Web.GeneratedImage control; [URL] to display the images.
I'm trying to add a "panel" with controls dynamicaly. Something like the code below, Clicking "Add" button, displays a "Panel" with the controls(which are within a table), the number of "Education" someone can enter is unlimited. I know how to capture the data, but i can't figure out how to implement/code this,
I understand the page lifecycle and how i need to add the dynamic controls on page_init if I want to take advantage of viewstate. Also I know that I should try to avoid dynamic controls when possible. The dynamic controls are created depending on an object that is created from custom event arguments sent from a custom treeview. Problem is I need viewstate so I need to create them in page_init but I don't have the event args to create the object that tell me what controls to add until later in the lifecycle.
Private Function GetEventArgs() As npTreeViewEventArgs Dim control As Control = Nothing Dim e As npTreeViewEventArgs = Nothing
[code]....
I use this in page_init to create my object and controls.
I've successfully been able to add controls (labels, images, buttons, etc) to a panel control (using VB/ASP). This panel control, I refer to it as "insertpanel". Then I add this panel to the main panel on my webpage which I made during design time. The problem I run into is that when I add multiple controls of any type to the panel, they are all added in line with each other. I tried giving my image some css-styling of[code]....
I am looking for the best way to dynamically arrange the location of labels (or any control for that matter) during runtime in a Windows Forms application using VB.net or C# in VS2008.I have a control that displays messages created by users.This control has a panel docked at the top which holds the header information for each message, called pnlHeader There are 8 labels: 4 of them display static descriptions (e.g. "To", "From", "Created Date", "Completed Date")And the other 4 display the relevant data for those descriptions. (Passed in during runtime from a MS SQL 2005 DB).Static labels are named: lblCreatedDateLbl and dynamic ones: lblCreatedDate The application runs on monitors of various size and resolution, therefor I would like for all of the labels to arrange themselves with equal spacing in pnlHeader, based on the current width of the panel.
At first, I had simply created the labels in the Designer and used Anchors (half of the lables were set to (Top, Left) and the other half to (Top, Right)). This solution worked for most scenarios, but did not always provide a consistent solution, so I decided to add the controls in code instead.
I thought it would be easier to work with the labels by creating a panel for each corresponding pair. So pnlCreatedDate would hold lblCreatedDateLbl and lblCreatedDate I wrote 2 methods: 1 to define each label and add it to the relevant panel: Sub AddLabels and another to determine the width of the panels and set the correct location: Sub SetLoc Currently, AddLabels runs in the constructor after InitializeComponent() and SetLoc is called after the data has been passed in from the database.
I've tried making minor changes and tweaks to the width and size parameters, enabling and disabling AutoSize, but nothing returns a consistent solution, instead either all the description labels are misplaced, or do not appear at all or completely whack locations come up.
Private Sub AddLabels() 'Label Created By:' lblCreatedByLbl.Location = New Point(0, 0)
I'm wondering, when I add dynamically controls in runtime in the form - is there a way to save this controls, and they appear the next time when you run the application?
I'm developing a website in visual studio 2008 using (asp.net/vb)I have to allow registered users to build pages and add controls that are already defined by the same userMy problem is how to build this page dynamically?In other words, I'd like to make like any CMS (e.g. Joomla). CMSs allow us to make new pages and add our controls then save them..
I am working on a project for a handheld in Visual Studio 2008 where I need to add a group of labels to a panel that correspond to a record on the database. The record is a "Pass/Fail" Record. So, if the record is a "Fail", the failed items will be added below the main group of labels; therefore, many child groups of labels will be added below the main group, which is theoretically the header record. I am using a second panel to add the failed items. My issue is how to dynamically add, name, and position the failed item labels and panels. Below, I have included a sample of what I am trying to accomplish.
What I am trying to do is dynamically create a bunch of dropdown lists and then I want to loop through them and update the database with those values, but the problem I am facing is that I create the dropdown lists, but then when I go back to loop through them they are no longer in the panel. I don't know why but when I am debugging I have a count of 50 controls in pnlTeacherSelect right up until I press the button that calls prcChoose.
This dynamically created content is mostly dropdownlist boxes in the format of
<form method=post action="/questions/nextBatch"> <div id="text">What is your preferred drink?</div> <select>
[Code]....
Is it is possible to perform validation on the dropdowns lists to ensure that a value has been selected? If any of the dropdownlists that still have the default value (the "please make a selection" text) the page is then redisplayed with the font colour of the question or dropdownlist box changed to say red?
I'm from the Webforms world and have made the switch over to MVC (which I really like!) and I know there are some pretty slick validation tools out there but you seem to have to account for them within the view itself.
I cannot pass a HTML helper through the viewdata of the controller as it does not render unless it has been coded directly into the view itself.
Also, I'm looking for a pure asp.net solution as I cannot use javascript due to accessiblity concerns. I can access all the values of the dropdowns without any problems throug the formscollection object but from there I'm a bit stuck.
like this i have n number of questions in my word document. so my need is i need to read the questions and fill it up in the datagridview with yes or know chek box. my datagridview appearance would be as follows. so the peson who is viewing the questions and can make yes or know option using the check box.if the person chooses no option he has to enter the reason the reason column. so i have to do this dynamically. means that binding datagridview with checkbox ,textbox, data dynamically. how to do this please because after the datas entered in the datagridview i have to loop through rows and i have populate into another word document. so please if there is any sample
Now from Serverside code I have added 3 rows dynamically.. when ever page gets Postback.. all dynamically added rows get disappear.How can i get the dynamically added rows after postback??
How would I dynamically enable/disable group boxes based on a radio button selection? I am trying to do it with two group boxes. The group boxes are called grpSelectChars and grpPWAutomatic. The radio buttons are called rdoChooseChars and rdoRandomlyGen. if rdoChooseChars is selected then I want grpSelectChars Enabled and grpPWAutomatic Disabled. in the load sub I have rdoChooseChars Checked
Private Sub PWGenerator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load rdoChooseChars.Checked = True If rdoChooseChars.Checked Then
I have been set a project from school to design snake in VB.Net but i am struggling to dynamically add the user control which acts as one of the dots in the body of the snake. Every time i add a dot on to the snake the previous vanishes. I assume this is due to me overwriting the previous one by creating a new instance of the object but i cannot find a way of adding a new one in.[code]I have tried using body(i) and other ways of adding a new instance of the object but am stuck.The subroutine will be called up when a new control is needed.
