I'm trying to convert an asp.net website to a vb.net application. It's my first go with vb.net so please try and make any responses as simple as possible.On my website I have a page that uses nested repeaters. The data source is a dataset with relations.Im trying to replicate this in a form. I've created my dataset and relations, but I'm struggling to find the best way to display my data within the form. For each parent row there can be a varying amount of child rows. The parent row simply shows an index number via label. The child rows contain text that can vary from a single character to 1000 characters.I have tried to use a dataRepeater as the parent control and a datagridview as the child control.I'm struggling to find out how, and at what point, to bind the data to the datagridview.
Iam using nested repeaters with Dataset (not using Datatable) to retrieve information by passing parameters. So far I have bind the two repeaters clearly and everything is working fine.Here the list of messages created by each user datawise(parameter passed) will be displayed, and there could be more than 50 messages created by each user daily, So now I want to do custom paging for each user.But Iam unable to proceed further, as the next, previous, back, first links are placed inside the child repeaters footer template and i coudn't access these links even by findcontrol method.
I'm having lots of trouble understanding how repeaters are supposed to work and how I'm supposed to use them. Basically, I have a label, a set of image buttons, and a div within a repeater. When you click on the button, I want to populate the div that was created with these repeaters (so a different div for each iteration of the repeater).[code]I can't get the repeater to iterate. It's only firing off once and then stops. I can't get a label with the repeater data source's Subject (a field in my database) to appear.
I'm migrating a VB6 application, which has a subroutine that fires upon a QueryClose form event. As far as I can tell, this event no longer exists in System.Windows.Forms. I tested with a breakpoint, and QueryClose does fire when you click the red 'X' in the upper right corner of the VB6 form, like the FormClosing event is supposed to do in VB.NET forms. My question is: Does FormClosing have the closest equivalent functionality to QueryClose, or should I use a different event? [code]This code was originally VBA / VB6, which I put through ArtinSoft's Visual Basic Upgrade Companion (VBUC). VBUC apparently didn't think that there is an equivalent event, or isn't smart enough to do that sort of conversion. FWIW, I'm using Microsoft Visual Basic 2010 Express.
code For Each item As Reflection.FieldInfo In GetType(NameSpace.ClassWithNestedClasses).GetFields rtfAppend(item.Name & ":" & Tab & item.GetValue(Me)) Next For Each item As Reflection.PropertyInfo In GetType(NameSpace.ClassWithNestedClasses).GetProperties()
[code]...
which gets me the simple string vars and properties of my top class, but how can i apply this to loop through all sub classes and get there vars and props?
I just want to know if there any equivalent event (ADO. NET VS 2008) event as in MS ACCESS Form's OnCurrent Event.
The reason is I like to make some calculations based on some data bound controls with current datarow data when user clicked a row in DataGridView (or by using bindingNavigator). I've tried with DatagridView's RowEnter event. But some Data bound controls are not yet reflect the data of current datarow when that evet was fired.
In MSDN Help File: It says "RowEnter Event: Occurs when a row receives input focus but before it becomes the current row. "
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 am using nested datalists to display hierarchical data. In the nested datalist i want to be able to bind to a property that belongs to the object that the parent datalist is bound to.
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 have been trying to read the cd toc in one go from the API, I can read it OK with a single byte array, but I can't find a way to fill the formatted arrays
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 am new to this forum so please be patient with me :-) My problem is how to bring a nested XML structure into a single DataGridView. The XML looks like this:

All I would like to do is populating a DataGridView with 4 columns (Name, Age, Language and Artwork). Each of which containing its appropriate value whereas the latter will contain all pictures... See what I mean?
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) Dim strSQL As String
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 constructing some XML using XML literals. I have a function which returns an XElement.
Function RootElementFormattingFunction() as XElement Return <Root Data="foo"/> End Function
In reality it is a bit more complicated than that, but it is called from several places. Now I have linq sequence which generates a set of nodes which I want to make children of the XElement returns
I am trying to add some items to a TreeView Control: TV1.Nodes.Add("key1", "Test1") 'Works TV1.Nodes("key1").Nodes.Add("key2", "Test2") 'Works (Nested) TV1.Nodes("key2").Nodes.Add("key3", "Test3") 'Error (NullReferenceException)
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 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):
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 ' Find the nested DataSource control in the DataList.
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.
'Classic ADO Code Dim rsOuter as New ADODB.Recordset Dim rsInner as New ADODB.Recordset
I intended to do another SQL query inside here and retrieve data from another table by using the "category_id".I know the problems that asp.net required me to close the data reader before proceed to another query. But is there any solution for me to do another query and open another data reader within the opening data reader? [code]
