RadComboBox loadondemand resets position when data is fetched.

Hi.

As stated in the title, the position keeps resetting to the 1st element in the combobox as soon as new data is added to the combobox. Below is the itemrequested code I use.

Protected Sub cboInstrument_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)

Try

Dim oSender As Telerik.Web.UI.RadComboBox = DirectCast(sender, Telerik.Web.UI.RadComboBox)

oSender.DataValueField = "Name"

oSender.DataTextField = "Name"

Dim data As List(Of Instrument)

If Not String.IsNullOrWhiteSpace(ExchangeComboBox.SelectedValue) Then

data = GetData(ExchangeComboBox.SelectedValue, e.Text, False)

Dim itemOffset As Integer = e.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + ItemsPerRequest, data.Count)

'e.EndOfItems = endOffset = IIf(data.Count = 1, 0, data.Count)

e.EndOfItems = endOffset = data.Count

For i As Integer = itemOffset To endOffset - 1

oSender.Items.Add(New RadComboBoxItem(String.Format("{0} - {1}", data(i).Symbol, data(i).Name), data(i).ExchangeSymbolKey))

Next

e.Message = GetStatusMessage(endOffset, data.Count)

Else

Dim endOffset As Integer = 0

oSender.Items.Add(New RadComboBoxItem("Select an Exchange", Nothing))

e.Message = GetStatusMessage(endOffset, 0)

End If

Catch exc As Exception

ProcessModuleLoadException(Me, exc)

End Try

End Sub

Any help will be greatly appreciated.

Regards

[Solved] get_masterTableView not working

I've had a tough time trying to figure out how to access my grid on client side. I've tried everything I could find, and nothing seems to work. I FINALLY got my grid object ($find didn't work for me), but now get_masterTableView() isn't doing anything. If I step through the javascript, it steps into the line and just disappears into some WebResource.axd abyss and never returns. I don't get any javascript errors.

If I try to run the function in the console, it says "undefined is not a function".

Here's my code

<script type="text/javascript">

function GridCreated(grid) {

var mtv = grid.get_masterTableView();

var pageIndex = mtv.get_currentPageIndex();

alert(pageIndex);

}

</script>

<radG:RadGrid ID="rgResults" runat="server" AllowMultiRowSelection="True" AllowPaging="True"

AllowSorting="True" EnableAJAX="False" GridLines="None" OnItemCommand="rgResults_ItemCommand" OnItemDataBound="rgResults_ItemDataBound"

PageSize="20"

Skin="Default" Width="100%" OnPageIndexChanged="rgResults_PageIndexChanged" OnSortCommand="rgResults_SortCommand" OnInit="rgResults_Init" OnPreRender="rgResults_PreRender">

<ClientSettings ApplyStylesOnClient="True">

<ClientEvents OnGridCreated="GridCreated(this);" />

TreeList Scrolling and Offset Header in Chrome

Hi

I have a RadTreeList within a RadAjaxPanel which was working well until I decided to make the tree scrollable. Now I find that when I view the tree in IE everything seems OK but when viewed in Google Chrome the header for the tree list is offset by about 50% of the width of the tree which obviously looks odd as now all of the column headers are not above the columns they refer to. My tree is defined using :-

<telerik:RadTreeList ID="componentTree" runat="server"
AutoGenerateColumns="False"
AllowSorting="True"
BeforeClientContextMenu="ShowContextMenu"
DataKeyNames="ID" ParentDataKeyNames="ParentID"

[Solved] background of style to fill whole page

I am using SkinManager and RadDecorator to apply skin to pages. This is working fine as long as the content fits the window size. If the content goes beyond the window size and the user needs to scroll down the page any skin with a background colour there is an issue. The background colour ends and as you scroll the remainder of the page the background is white. How do I extend the background to the height of the content?
