Getting Index out of bound error

[Balkar]

Hi, When i tried to bound a datatable, I am getting index out of bound error:

 Dim table As New DataTable()
            table.Columns.Add("CallID", GetType(Integer))
            table.Rows.Add(12345)
            table.Rows.Add(67890)
           dgCallSearch.DataSource =table
           bgCallSearch.databind()



<Telerik:RadGrid ID="dgCallSearch" runat="server" CssClass="DataGridTable" AutoGenerateColumns="false" Visible="true" OnNeedDataSource="dgCallSearch_NeedDataSource1">
<ItemStyle CssClass="DataGridItem"></ItemStyle>
<AlternatingItemStyle CssClass="DataGridItem"></AlternatingItemStyle>
<HeaderStyle CssClass="DataGridHeader"></HeaderStyle>
                                        <MasterTableView>
<Columns>
                                                <Telerik:GridBoundColumn DataField="CallID" HeaderText="ID">

                                                </Telerik:GridBoundColumn>
                                            </Columns>
</MasterTableView>

</Telerik:RadGrid>

Hi Balkar,

When using the advanced databinding of the grid you should not call the databind() method of the control. Also, the control that gets databound is not the grid whose datasource was just assigned but some other control. Once I remove the call to  bgCallSearch.databind() things worked fine with me. I added the code-behind you pasted in the OnNeedDataSource event handler.

On a side note - I advise that you post your issues in the most relevant section of the forums, because this case is related to RadGrid and not to RadTooltip.
