Lets say I have a tablecell and I want to add to it more then one control To HyperLinks for example (I know its ASP.NET but I guess its the same cause its still visual Basic) I can add one control by using
TableCellID.Controls.Add(NewHyperLink)
But if i want to add another Hyper Link, How do I do that ?
I have a website which is code generating practically everything on the page. The home page consists of a right menu which is being built via code. It uses ystem.Web.UI.WebControls.TableCell class and creates a td for every new item.ere is a snippet of the code:

ByVal Contents As DataTable, _
ByVal ReadMode As Boolean, _

I've a asp.net table and I'm trying to format my columns to be all equal widths, or say 4 columns of 20%, 30%, 20% and 30%. However the following code is not working:
<asp:TableCell Width="30%"> The 'height' attribute works but this isn't the one I'm after.
i frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
I am programmatically creating a Tabcontrol and adding Tabpages to it. To each Tabpage, I am adding 2 Pictureboxes (Testpicture1 and Testpicture2). The amount of Tabpages depend on the amount of frames in my .tif file. So, each picturebox holds an image (frame) from my .tif file sequentially from˜0 to totalpages. All good so far. I can click each tab and correct images are displayed in correct order. The problem is that when I drag a control (picturebox) and try to add it to Testpictue1 or Testpicture2 it does not work correctly. At first I thought the it didn't work at all, but when I checked each Tabpage I have found that all pictureboxes got added (draped) to my last Tabpage, in this case Tabpage4. So this is puzzling. Even though each Tabpage holds 2 Pictureboxes and they display the correct images yet the picturebox is added to the Testpictue1 or Testpicture2 of the last created Tabpage? [code]
View 3 RepliesThis question is about VB.NET. I'm quite a novice on this one, so please forgive me if you feel that this question is nothing short of crazy or whatever. Anyway, I've been a creating a simple Windows addressbook Form application. We all know for a fact that a single person can have one or more addresses, of which a one-to-many relationship holds true. So there, my application also has to be able to edit each of these addresses (by the way, my application uses an Access Database, which really sucks but it's part of my task), and I already thought of using a control array (just like in PHP but it obviously never worked in .NET) for me to edit them. How am I supposed to implement this?

View 2 RepliesI'm looking for adding a control on top of others controls during runtime.
I read that the only way of playing with the Z-Order of controls is by playing with the order of the controls inside the Form.Controls Collection. I find this solution very weird and weak and I'm looking for an alternative.
Does anyone has an idea? I just want to make some kind of modal dialog that'll show below another user control to notice the user that the user control is currently doing something.
Edit: I tried using Control.BringToFront() but it doesn't work at all.

View 14 RepliesI have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

how to add an icon to a user control - I'm talking about the icon that shows up in the toolbox.

Wasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
