[Solved] ColumnGroups throws error if datasource is nothing

[Morten]

Hi,

RadGrid throws an 'Index was outside the bounds of the array' error when using ColumnGroups and having datasource=nothing.

Version 2016.1.113.45

Example throwing error (dont bind grid to datasource):

<telerik:RadGrid  runat="server" ID="rg">
    <MasterTableView>
        <ColumnGroups>
            <telerik:GridColumnGroup HeaderText="Invoice" Name="Invoice"></telerik:GridColumnGroup>
        </ColumnGroups>
        <Columns>
        <telerik:GridBoundColumn ColumnGroupName="Invoice" HeaderText="Test" DataField="Test"></telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

 

Working:

<telerik:RadGrid  runat="server" ID="rg">
    <MasterTableView>
        <ColumnGroups>
        </ColumnGroups>
        <Columns>
        <telerik:GridBoundColumn  HeaderText="Test" DataField="Test"></telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
