The scenarios:

I have a MasterTableView and it contains one DetailsTable. And the GridTableView contains a button in its CommandItemTemplate section. I want to fetch the parent table ID (MasterTableView) against the button click in the hierarchical child table (GridTableView). The e.CommandArgument property in the grid's ItemCommand event is empty.

 

The markup for the CommandItemTemplate is below:

 

<CommandItemTemplate>
                                <div style="padding: 5px 5px; text-align:right" >
                                    <asp:Button ID="btnSaveAction" runat="server" SkinID="Save" 
                                        CausesValidation="false" Text='​Save'  CommandName="​Save" CommandArgument='<%# Eval("ID") %>' />
                                </div>
                            </CommandItemTemplate>​

Hello,

Please try with the below code snippet.

 

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    OnDetailTableDataBind="RadGrid1_DetailTableDataBind" OnItemCommand="RadGrid1_ItemCommand" AutoGenerateColumns="false">
    <MasterTableView DataKeyNames="ID">
        <Columns>
            <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID"></telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name"></telerik:GridBoundColumn>
        </Columns>
        <DetailTables>
            <telerik:GridTableView DataKeyNames="ID" CommandItemDisplay="Top">
                <CommandItemTemplate>
                    <div style="padding: 5px 5px; text-align: right">
                        <asp:Button ID="btnSaveAction" runat="server" SkinID="Save"
                            CausesValidation="false" Text='​Save' CommandName="​Save" CommandArgument='<%# Eval("ID") %>' />
                    </div>
                </CommandItemTemplate>
                <Columns>
                    <telerik:GridBoundColumn DataField="ID" UniqueName="ID" HeaderText="ID"></telerik:GridBoundColumn>
                    <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name"></telerik:GridBoundColumn>
                </Columns>
            </telerik:GridTableView>
        </DetailTables>
    </MasterTableView>
</telerik:RadGrid>

protected void RadGrid1_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)
{
    dynamic data = new[] {
        new { ID = 11, Name ="Name_11"},
        new { ID = 22, Name ="Name_22"}
    };
    e.DetailTableView.DataSource = data;
}
 
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == "Save")
    {
        string strParentID = (e.Item.OwnerTableView.ParentItem as GridDataItem).GetDataKeyValue("ID").ToString();
        // Access the master table's datakey here
    }
}

 

Let me know if any concern.

Thanks,

Jayesh Goyani
