Nested ASP.Net Controls Not Defined
Aug 18, 2010
I have a couple of controls that are set to runat="server", but are showing up as "not declared" in the vb code behind. They are not being setup in the designer.vb file at all, even if the design.vb is re-created.
The only thing that I can think might be causing this is that the controls are inside of a custom control. The code looks something like this (it has been modified because of NDA):
<abc:MyCustomControl>
<additionalItems>
<asp:CheckBox id="coolCheckboxOfPower" runat="server" Text="Triple Rainbow!">
[Code]....
So using the example above, if I try to use coolCheckboxOfPower in my vb page, it says it is not declared.
It has been suggested to me that asp controls cannot be nested. Is this true, and if so, how do I get around that?

I have form, on which a component is placed, which is inherited from Forms.UserControl. This component, called Panel, handles the layouting as visible in the screenshot below.
The screenshot shows 10 Panels. Each Panel contains its own title bar and visible area, in which any UI can be displayed.When the application starts, the application contains only one single Panel. When the user decides to split this Panel into 2 Panels, those new Panels are displayed side-by-side in the area of the old Panel either horizontally or vertically. Inbetween these Panels a splitter is added, so that the user can resize the Panels. The user can do the splitting multiple times, so that you reach a layout as given in the screenshot above with 10 Panels.
Minimizing and the maximizing the application causes a painting issue as displayed in the screenshot below. The red rectangle indicates the area, where the layout is not displayed properly.
Here some additional information:
1. Windows 7 The issue occurs only on Windows 7 machines. On Windows XP the application is running properly.
2. .Net Framework The application was developed for the .Net Framework 1.1. I upgraded it to 4.0. All warnings were fixed, which occured after the upgrade to 4.0.
3. Layouting Technically The Panel works internally with mutiple Forms.Panel, 1 Forms.Splitter etc. objects. If the Panel is not splitted, it displays the title bar and a visible area below, both instances of Panel. If splitted, the Panel replaces the title bar and visible area with 2 instances of Panel again but divided by a Splitter.

I have a nested custom control that I need to set focus on. I have it all internally wired up to automatically set the focus when the form loads, but when it comes up on screen, the designated accept button for the parent form is in focus instead. Even when is disassociate the accept button it still does not set correctly. How can I ensure my desired control gets focus.

I have a panel sitting in a div, and I want to use that panel as a container to add more panels! Why would I want to add a panel to a panel? Because the panel that I'm adding to the existing panel, is also made to contain objects, but only and image and label.
The existing master container panel is created during design time, and goes by the lovely name of "toolboxpanel". During run time, I have a for/next loop that dynamically creates an image, a label, adds them both to a panel, then adds that panel to the toolboxpanel,[code]...

How do you get a specific nested control of dynamically created controls (i.e. the child of a dynamic control)? The FindControl() method does not work because it only deals with TopLevel dynamic controls I believe.

I have an outer listview and inside its itemtemplate an inner listview. Each has its own SQLDataSource. A Id field from the outerlistview works as a select parameter for the second listview.
When stepping through with the debugger it works perfectly, unfortunately the rendered page only contains data from the outer listview. It appears the databinding of the outer listview fires and renders the page (including the inner listview) before the codebehind can provide a where parameter to the second listview. The aspx page is below.

I have an XML file which is a multitable nested xml file (.Tables.Count returned 12 tables). I would like to have all of the xml contents in one table or, if not, select different columns from these different tables (that are stored in XML) and put them in one table. As I understood Datagridview only allows only one table at a time. Is there any way to create a new datatable by joining exsting tables from XML?

I've a large table of Items and I need to organize them by Category, then by Year and then by Month.Item has CategoryID and Dated properties.I got this far:
Dim Items = From Item In DB.Items _
Group By CategoryID = Item.CategoryID _
Into Categories = Group _
Order By CategoryID
But where I put the:
Group By Year = Year(Item.Dated)
and the
Group By Month = Month(Item.Dated)
The final result should be something like this:
For Each Category in Categories
For Each Year in Category.Years

I'm working with a database that includes a table called MenuItems. The table is hierarchical, so an item can have child items under it. A record's ParentID corresponds to the ID of the parent record, or the ParentID can be 0 if the item is on the top level.What I'm trying to do is create a VB.Net application to populate a TreeView with the records in my MenuItems table, using the recursive function ListSubMenus in the code below:
Code:
Private Sub ListSubMenus(ByVal ptvnParent As TreeNode, ByVal plngParentID As Long)

I can't seem to find a lot on how to use events in nested objects. I suspect that I should have access to the events in the nested objects through intellisense if I had done things right. I have many objects with 50 or so properties and I would like to access them with out adding handlers for each one and additional events in parent objects.
Example:
Public Class Form1
Dim WithEvents myCombinedClass As New CombinedClass

I am working on a project that requires that I use nested case blocks. However, I am not quite sure what this looks like. And for whatever reason I'm having a hell of a time trying to find the answer through google. Are nested case blocks like nested if blocks? Or are they something completely different? More information on the project can be given if needed.

I have a datasource that needs to gather information for a label. These are both inside of a DataList that is connected to a different DataSource. When I debug my application, the value is Nothing. I thought I had the verbage right since there are no squiggly lines, but it isn't working.
I tried FindControl("dsPicklist") and DirectCast(FindControl("dsPicklist"), SqlDataSource) but neither one gets a value returned.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I am working in a proprietary language based on basic on a measuring machine. I delibritly set the first two checks to fail for testing purposes. The first set of ifs for size X works great. When the code is run and it gets to Size_Y, if the operator picks "no I don't want to remeasure" (returning a 7) the code jumps all the way to the last end if. I suspect I have improperly nested my Ifthens, but I can't see it.

How do you do nested recordset loops in ADO.NET? In ADO, you could just open one firehose cursor for the outer loop and a static, client-side, read-only cursor for the inner loop and nest the loops. But you can only open one DataReader at a time and Datasets aren't read-only.
