C# - Access DataLists Inside The ListView?
Oct 27, 2011I have a DataList (Question) inside the ListView (Section). ListiView is to hold the sections. DataList holds the questions of a section. Let's say I have 3 sections, each section has 2 questions.
<asp:ListView ID="lvSection" runat="server">
<LayoutTemplate>
<div id="itemPlaceholder" runat="server" />
[code]....
But it does not get anything back, question always gets nohting. I think it's because there are 3 DataList inside the ListView now, due to 3 sections, and it cannot find DataList dlQuestion anymore. How do I access these DataLists of ListView from the code behind? I need to loop through each control of the DataList .

Datalists In Asp.net - MyCommand.Fill(DS, "field1") And DS.Tables("field1").DefaultView Meaningless?
Oct 2, 2009I'm very new to asp.net and I have a general question about datalists. I was able to get this to work, but I don't understand how really. I think I need someone to give me the "theory" on this. So first I connect to the database:
[Code]....
Here are my questions:
- Why is the datalist pulling field2 successfully?
- Are the MyCommand.Fill(DS, "field1") and DS.Tables("field1").DefaultView meaningless?
- I guess my bottom-line question is, why do I have to specify fields in the vb if I can output any field?
ASP.NET VB Nested Listviews
Mar 29, 2011I 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.

Nested Xml To Table
Apr 2, 2009I 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?

DB/Reporting :: Using Nested DataReaders?
Apr 3, 2012I'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:

Events In Nested Objects?
Oct 17, 2010I 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.

How To Do Nested Case Blocks
Feb 29, 2012I 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.
View 10 RepliesNested ASP.Net Controls Not Defined
Aug 18, 2010I 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?
Nested DataSource Is Not Found?

View 9 RepliesNested If Statements Jump Over Other Ifs
Feb 24, 2012I 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.
