Hello,

My scenario is that i have a grid with single level nesting. Order is parent grid and orderaddress is the child grid.

I have a link on the parent order called assign. On assign click i get data key of orderid and build the object based on row columns
 var oArg = new Object();
 oArg.OrderId= selectedRow.getDataKeyValue("OrderId");
oArg.name= masterTable.getCellByColumnUniqueName(selectedRow, "Name").innerHTML;
oArg.age= masterTable.getCellByColumnUniqueName(selectedRow, "age").innerHTML;

All works till now.
The problem is i need to associate single address from the details grid. I have row selection for child grid. How do i get primary key and other objects from detail table?

For eg. if i have 3 rows expanded than i need to get the selected child object of the row on which the link is clicked.
Once i get the object i need to build following object
var vAddress  = new Object()
vAddress.AddressId = get addressid primary key from detailsview
vAddress.Address1 =  get address1 as innerhtml from the detailsview


Please help

Regards
Mac

Hello Mac,

In order to achieve this, In ItemCreated event attach "onclick" event to LinkButton and to pass the row index to the client event handler. In the event handler you can access the corresponding DetailTable and DataKeyValue of selected rows in that DetailTable. Sample code is given below.

ASPX:
 <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource3"
    <MasterTableView Name="Master" runat="server" DataKeyNames="OrderID" DataSourceID="SqlDataSource3"
       <Columns> 
          <telerik:GridTemplateColumn> 
             <ItemTemplate> 
                <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton> 
             </ItemTemplate> 
          </telerik:GridTemplateColumn> 
        </Columns> 
      <DetailTables> 
        <telerik:GridTableView runat="server" DataKeyNames="EmployeeID" ClientDataKeyNames="EmployeeID" Name="DetailTableView1" DataSourceID="SqlDataSource1"
                   . . . . . . . . . . . . . . . . . . 

C#:
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) 
    { 
        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name=="Master"
        { 
            GridDataItem item = (GridDataItem)e.Item; 
            LinkButton btn = (LinkButton)item.FindControl("LinkButton1"); 
            btn.Attributes.Add("onclick""ClientClick('" + item.ItemIndex + "');"); 
        } 
    } 

Java Script:
<script type="text/javascript"
    function ClientClick(index) 
       { 
        var grid = $find("<%=RadGrid1.ClientID %>"); 
        var MasterTable = grid.get_masterTableView(); 
        var row = MasterTable.get_dataItems()[index]; 
        var selectedItem = row.get_nestedViews()[0].get_selectedItems()[0]; 
        var detailkeyValue = selectedItem.getDataKeyValue("EmployeeID"); 
        } 
</script> 

Thanks,
Princy.

Hello Francis,

You can access the child grid by specifying the Name property for DetailTable as shown below.

C#:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "DetailTableView1")//here set the Name of child grid as DetailTableView1
   {
    GridDataItem item = (GridDataItem)e.Item;
   LinkButton link = (LinkButton)item.FindControl("LinkButton1");
   }
}

Thanks,
Shinu.

Hi,

I have a 3 level nested radgrid. I would like to get the specific record of the child table expanded when the page is opened.
For e.g, in this example, it is mentioned how the first row of the first child grids can be expanded. But it has not been told that how I can expand the 3rd row. So for the above example, I would like to programmatically find 10507 inside ANTON and then expand it.

Thanks,
Sharmin
