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.

I am dynamically creating and adding a ComboBox to a specified column in DGV. I also set a DataSource, DisplayMember and ValueMember for the created ComboBox. Somewhere else in my program, I select a number ( let's say 5 ) and based on that number I want to change the SelectedIndex of the current ComboBoxColumn ( I actually loop through the Columns collection ).I tried something like this in a event handler I created:
vb.net
Private Sub combobox_validated(ByVal sender As Object, ByVal e As System.EventArgs)
Dim combobox As System.Windows.Forms.ComboBox = sender
Dim colIndex As Integer = combobox.Tag
[code]....
You will notice here, that I'm not actually trying to change the .SelectedIndex property, but the Value of the current cell.How do I reference the actual ComboBox?

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.

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.

I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second
My HTML
<div id="showHere" runt="server"/>
VB
Dim thisPh As New PlaceHolder
thisPh.Controls.Add(showTable)
showHere.Controls.Add(thisPh)
Dim anotherPh As New PlaceHolder
anotherPh .Controls.Add(showTable)
showHere.Controls.Add(anotherPh)
How do I make it add repeated tables within the showHere div?

I'm making a LAN instant messenger and I'm trying to achieve something similar to how MSN will open a new chatting window when you double click on a friend. My main form has a list of friends, and I want to create a new chat window when they double click on one of those friends. I've created a "template" chat form which I want to generate dynamically, and I've run into some problems I need help with. Lets look at the code I already have.
[Code]...
Now, call me a newb if you will, but I really don't know much about threading and all that hocus pocus. Some guidance in the right direction would be great.
EDIT: ClientWind is the chat form.EDIT: That's weird. It doesn't occur with the actual builds.

I am using CompilerParameters to dynamically compile code... The problem is when I use:
cp.ReferencedAssemblies.Add(CompilerPath & "est.exe")
to add a reference to test exe ... (where CompilerPath is the full path name)
Compiler Path is not the Compiler Application Path
I get an error when compiling stating that:
vb
"Could not load file or assembly 'test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."
If I put it in the test.dll in the "compiler apps" path and then call ReferencedAssemblies.Add with the full path it works.

I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

So say I have a dropdown control, and after the user uses the drop down, I want a checkbox and label to appear, AJAX style, without a full postback.
How can I implement something like this? Examples of code (or links to them) would be great.
I played around with this some using updatepanels but I can't get it working right...

I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.
Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....
Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically.

I have a panel that is a set size and has its Autoscroll property set to True.I am parsing text files and then adding them to the panel. I'm extracting specific lines and then adding them to labels and text boxes that are in the panel.When my app runs, it can parse anywhere from 0-10 files at a time.If there are no files to parse, I don't want any controls in the panel. I'll be creating the controls based on how many text files I have. For each text file, I'll have 3 controls.
I'll count the text files before I parse them, and insert the controls into the panel.The problem is that I don't know how to place the controls based on the location of the panel/form. I know the panel will always have a permanent spot, but I won't know if the location parameters of the panel have changed because I won't know how many controls there will be before the app parses the files.
However, I will know the size of the controls that I'm inserting.So, with all of that, is there a way to insert the controls inside of the panel, and then based on that information, insert the others?

The editor basically uses a bunch of labels and pictureboxes (for now) and then an image is created from the panel which contains all of the controls.It sounds quite confusing, but basically i'm trying to create something like visual studio itself, which will allow "controls" to be added onto a panel, and then everything can be exported as an image when the user chooses to.I've worked out all the code to move controls and exporting the image, just having trouble trying to work out how to add an event for newly created controls as you can only handle a control, and not a variable.

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?

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?
