Hey there,
I'm currently facing following problem:
On an ASP.NET page there is a RadGrid that gets filled on client-side using a SignalR connection.
The databinding is done like this:

The grid is filled and the data is displayed correctly. 

During a postback caused by a button click I need to access the data in the server-side code but the grid seems to be empty. The grid doesn't have a datasource and the ItemsCollection is empty. Did I forget something or is this scenario not supported?

Best regards,

Christian

I know this has been discussed multiple times in the forum, but unfortunately I was unable to find a solution that was working for me.  So here it is again.  Please someone help! :)

 Here is the code 

<AxnGrids:AxnGrid AllowMultiRowSelection="False" AllowRowClickEventPropagation="True" AllowSorting="True" AutoGenerateColumns="False" 
EnableEmbeddedSkins="False" EnableViewState="True" Height="100%" ID="TimeCardsGrid" InitialResizeToFit="True" 
OnItemDataBound="TimeCardsGrid_OnItemDataBound" OnNeedDataSource="TimeCardsGrid_OnNeedDataSource" runat="server" Skin="TMW_v1" 
TabIndex="-1">
<MasterTableView EditMode="EditForms" AllowMultiColumnSorting="True" TableLayout="Auto" EnableColumnsViewState="True" EnableViewState="True" >
<Columns>
<%-- columns returned: empid, emptimeid, startdate, enddate, status, empdrvid, approved --%>
<telerik:GridBoundColumn DataField="TimecardId" HeaderText="Timecard" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" HeaderStyle-Width="100px" />
<telerik:GridBoundColumn DataField="StartDate" HeaderText="Start Date" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" HeaderStyle-Width="100px" />
<telerik:GridBoundColumn DataField="EndDate" HeaderText="End Date" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" HeaderStyle-Width="100px" />
<telerik:GridBoundColumn DataField="Approved" HeaderText="Approved" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right" HeaderStyle-Width="100px" />
</Columns>
<SortExpressions>
<telerik:GridSortExpression FieldName="TimecardId" SortOrder="Descending" />
</SortExpressions>
</MasterTableView>
<ClientSettings>
<ClientEvents OnGridCreating="FixGridSizers" OnRowDblClick="raiseServerCommandRowDblClick" />
<Resizing AllowColumnResize="True" ClipCellContentOnResize="False" />
<Selecting AllowRowSelect="True" />
<Scrolling AllowScroll="True" EnableVirtualScrollPaging="False" UseStaticHeaders="True" />
</ClientSettings>
</AxnGrids:AxnGrid>

When this is run, i get the error "An item with the same key has already been added".  if i comment out the line between the SortExpression, it works fine.

Any suggestions

Hi,

I've seen this use of the template which styles each tab - http://demos.telerik.com/aspnet-ajax/tabstrip/examples/functionality/server-templates/defaultcs.aspx

 Is there a way to have a specific tab that contains a radbutton?

thank you

I know that I can localize the GridHeaders like the below

Protected Sub MyGrid_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles MyGrid.ItemCreated​

  If TypeOf e.Item Is GridHeaderItem Then
    Dim headerItem As GridHeaderItem = CType(e.Item, GridHeaderItem)

    Dim header As GridHeaderItem = CType(e.Item, GridHeaderItem)

    header.Cells(9).Text = Resources.PageLocalizations.GridHeaderApp
    header("Active").Text = Resources.PageLocalizations.GridHeaderActive​

  End If

End Sub

But the headers in Insert/edit mode doesn't get changed when using EditMode="PopUp"

Anyone knows how to edit the headers there?

Best Regards Pelle

I'd much rather comment out a Telerik line in HTML than remove it.  Using <!-- --> yields an error.  Is this this possible?

hey

im using advanced databinding with data from sql db.

so i have this code that when a column (files recieved) is sorted, i highlight rows that a month has passed since the since it was created, files were received but still it was not processed (to alert users). I had the idea i will add an unbound column, and assign it a priority number for the rows that are highlighted. There will be different priority for different "rules", so i could have some rows highlighted red with priority 1, while some are yellow with priority 2. now when this happens i want to create a default sort, before any other sorts are applied, that the rows with highest priority will show up first.

so thats the jist of what im trying to do. i know the regular sort wont work because the item is not bound, so its not a dataitem. what i tried to do was on the onneeddatasource event, after i have my datatable, i apply the sort by priority on the dataview of the datatable (the datatable does have the column with priority with the proper values). This seems to work as the datatable i assign as the datasource for the grid does show up in the exact order it should, priority items first. But i see that the other sort expressions of other columns are not yet applied, this leads me to believe that the datasource gets sorted after the event, overwriting the manual sort i applied. 

is there an event i should override where i can plug in my manual sort? or maybe someone has a better idea how to implement the functionality im looking to achieve? here is the relevant code:

on the item databound event i set the priority values for the rows and datatable stored in cache
