Beginner's problem with RadGrid and LinqDataSource

I have a 4.0 RadGrid on my page that I'm trying to bind to a LinqDataSource. I originally tried to bind the grid to a LinqDataSource that had a detailed select statement that included crossreferences to foreign keys. This did not work when it came to updates.

2 questions.

1. Do I understand correctly? The only way I can get Linq to automatically take care of updates is to not have a Select statement in my LinqDataSource.

2. If (1) is correct then am I also correct in assuming that if I want cross-references to other tables I need to manually code them in the <Grid name>_ItemDataBound event?

Upgrading telerik dlls from .NET 2.0 to .NET 4.5

Hi,

We are currently using Visual Studio 2005 for our ASP.NET web site. We bought telerik .NET 2.0 dlls and used them in the web site.

Now, we want to upgrade to Visual Studio 2012. If we buy telerik .NET 4.5 dlls, would it work or do we have to do some manual code changes?

Also, Is there is a converter or tool that can help us with?

Thanks.

RadComboBox Postback Question

I'm trying to do a database lookup based on what the user selects from the radcombobox. The SelectedIndexChanged event isn't firing. Well, actually, it does fire but I'm not seeing the result of the postback (textbox.text = result) until I change a different field on the form (RadTextBox field). When I change the value of that field the TextChanged event runs and does what it's supposed to and I can then see the result of the SelectedIndexChange event from the combobox.

I omitted some of the fields on the input form for simplicity and changed some of the SQL. I may have some unmatching divs and stuff like that but you can ignore it.

Any help would be greatly appreciated.

Thanks.

Removing rows on "Del" key press

Hi,
I need to remove the rows in radgrid on click of "Del" in keyboard. So I browsed the forum and got a solution to remove the radgrid rows from client side from this link
http://www.telerik.com/community/forums/aspnet-ajax/grid/delete-all-rows-in-a-radgrid-with-javascript.aspx#917286
So i got the below code

function keyPress(sender, eventArgs) {

// Del button pressed

if (eventArgs.get_keyCode() == 127) {

var masterTable = sender.get_masterTableView();

for (i = 0; i < masterTable.get_selectedItems().length; i++) {

var it = masterTable.get_selectedItems()[i];

var element = it.get_element();

element.deleteRow(element.rowIndex);

}

After selecting the rows and Del key clicked in keyboard the event is called correctly. But the value of get_selectedItems() is incrementing without the newly selected list of items. Lets say first time if I select 1 row then the value of masterTable.get_selectedItems().length is 1 then Del click removed the row. Next time when i selected 2 rows and checked the value of masterTable.get_selectedItems().length, it is 3.
Why the selected items length is incrementing without being refreshed to 0.
Is my approach correct?

If e.Item.ItemType = GridItemType.Item Then
If e.Item.OwnerTableView.Name = "Sales" Then
Dim DetailCode As String = e.Item.Cells(2).Text
Dim DetailSubCode As String = e.Item.Cells(3).Text
For Each Table As GridTableView In e.Item.OwnerTableView.DetailTables
If Table.Name = "Planning" Then
Dim Gv As GridView = Table.FindControl("GridView1")
Gv.DataSource = "Something"
Table.Controls.Add(Gv)
End If
Next
End If
End If

End Sub

Any help is welcome.

Thanks in advance,

René

force refresh on folder selection?

Is there any way to force a the grid to refresh when a treeview node is selected in the RadFileExplorer? On the first selection is appears to load up okay, but after that is seems to use the preloaded data. I need it to refresh each time the folder is selected if possible.
