a problem about RadGrid in RadGrid

[Ky]

Hello,
I used RadTelerik to show an grid in grid, here is my code in aspx file:

<telerik:RadGrid runat="server" ID="gridModulesList" BorderStyle="None" BackColor="Transparent"
            BorderColor="Transparent" AutoGenerateColumns="false" ShowHeader="false" Width="100%"
            AutoPostBack="true"  OnItemCommand="gridModulesList_ItemCommand">            
            <MasterTableView DataKeyNames="ID">
                <NestedViewTemplate>
                    <asp:Panel runat="server" ID="PnModuleDetail">
                    <telerik:RadGrid ID="gridModuleDetail" runat="server" AutoGenerateColumns="false" ShowHeader="false"  BorderWidth="0" Width="100%"
                            BackColor="White" OnItemDataBound="gridModuleDetail_ItemDataBound" OnItemCommand="gridModuleDetail_ItemCommand"
                            OnSelectedIndexChanged="gridModuleDetail_SelectedIndexChanged" OnNeedDataSource="gridModuleDetail_NeedDataSource"> 
                          <ClientSettings EnablePostBackOnRowClick="True" EnableRowHoverStyle="true" EnableAlternatingItems="true">
                            <Selecting AllowRowSelect="True" />
                        </ClientSettings>
                        <MasterTableView >
                            <RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">
                            </RowIndicatorColumn>
                            <Columns>
                            <telerik:GridBoundColumn DataField="ID" UniqueName="ID" Visible="false">
                                </telerik:GridBoundColumn>                                
                            <telerik:GridTemplateColumn UniqueName="Name">
                                <ItemTemplate>                                    
                                    <asp:Label runat="server" ID="lblName"></asp:Label>
                                </ItemTemplate>                                
                            </telerik:GridTemplateColumn>                                                                
                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>
                    </asp:Panel>
                </NestedViewTemplate>
                <RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">
                </RowIndicatorColumn>
                <Columns>
                    <telerik:GridBoundColumn DataField="ID" UniqueName="ID" Visible="false">
                    </telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="Name" UniqueName="Name" Visible="true">
                    </telerik:GridBoundColumn>                    
                </Columns>
            </MasterTableView>
        </telerik:RadGrid>


The problem is:
When I click on a item=> this item is selected and it's bold (item1)
I continue click on the other item item2=> item2 is selected and it's bold and item1 is still bold
Expected:
When I click on item2=> item1 is not selected and it's not BOLD

Hello Ky,

To achieve the desired functionality you should handle ItemCommand event of the nested grid, clear the selected indexes and set only current selected item as selected.

Here is the code:

protected void gridModuleDetail_ItemCommand(object sender, GridCommandEventArgs e)
    {
        if (e.CommandName == "RowClick")
        {
            foreach (GridNestedViewItem nestedItem in gridModulesList.MasterTableView.GetItems(GridItemType.NestedView))
            {
                RadGrid innerGrid = nestedItem.FindControl("gridModuleDetail") as RadGrid;
                innerGrid.SelectedIndexes.Clear();
            }
            e.Item.Selected = true;
        }
    }

I am also attaching a sample project which handles the needed functionality.
