[Solved] ClientSelectColumn on Sub Grid

[Jeff]

I'm trying to created a grid hierarchy as outlined in this example. I'm using the DetailsTables method (as opposed to NestedViewTemplate) and I would like to put a GridClientSelectColumn on the sub-grid, allowing the user to select only one item from each sub-grid. When i set the parent's AllowMultiRowSelection="False", however, this causes all the sub-grid's to act as a single group, allowing the user to only select 1 item from ALL sub-grids. The definition for my grid is as follows

<telerik:RadGrid runat="server" ID="ledger" Width="900px" AllowSorting="true" AllowPaging="true" AutoGenerateColumns="false" PageSize="10" AllowFilteringByColumn="true" OnNeedDataSource="ledger_NeedDataSource" OnDetailTableDataBind="ledger_DetailTableDataBind" AllowMultiRowSelection="False">
  <GroupingSettings CaseSensitive="false" />
  <ClientSettings EnableRowHoverStyle="true" EnableAlternatingItems="true">
    <Selecting AllowRowSelect="True"  UseClientSelectColumnOnly="True"/>
  </ClientSettings>
  <MasterTableView DataKeyNames="SubstanceId, Name, CAS" ClientDataKeyNames="SubstanceId"
        ShowHeadersWhenNoRecords="true" CommandItemDisplay="None" Font-Size="10">
    <DetailTables>
      <telerik:GridTableView runat="server" Name="SuggestedComponents" PageSize="5"
            AllowFilteringByColumn="False" AllowSorting="False" AutoGenerateColumns="False" ShowFooter="True">
        <Columns>
          <telerik:GridBoundColumn HeaderText="Name" UniqueName="SuggestionPrimaryName"
               DataType="System.String" AllowSorting="False" AllowFiltering="False" DataField="PrimaryName" />
          <telerik:GridBoundColumn HeaderText="CAS" UniqueName="SuggestionCAS" DataType="System.String"
                AllowSorting="False" AllowFiltering="False" DataField="CAS" />
          <telerik:GridClientSelectColumn UniqueName="SuggestionSelect" />
        </Columns>
      </telerik:GridTableView>
    </DetailTables>
    <Columns>
      <telerik:GridBoundColumn AllowSorting="true" DataType="System.String" UniqueName="SubstanceName"
            HeaderText="Name" DataField="Name" />
      <telerik:GridBoundColumn AllowSorting="true" DataType="System.String" UniqueName="CAS"
            HeaderText="CAS" DataField="CAS" />
      <telerik:GridBoundColumn AllowSorting="true" DataType="System.String" UniqueName="ProductCode"
            HeaderText="Product Code" DataField="ProductCode" />
      <telerik:GridBoundColumn AllowSorting="true" DataType="System.String" UniqueName="ClientSubstanceId"
            HeaderText="Client ID" DataField="ClientSubstanceId" />
    </Columns>
  </MasterTableView>
</telerik:RadGrid>

How can I achieve a single-select-per-sub-grid behavior?

Hello Jeff,

I am afraid you have manually implement this functionality.  A possible solution is to check whether the table has a selected item and remove it from the SelectedItems collection. You could achieve that by hooking OnRowSelecting client side event.
