Hi Sridevi,

I hope you are adding the detail tables declaratively in the aspx page. If so:

1. You can set multiple ClientDataKeyNames and access it on the client side.

  ASPX:
 <MasterTableView DataSourceID="SqlDataSource1"  EditMode="inplace"  ClientDataKeyNames="ProductName,ProductID" > 
                  
 
JS:
<script type="text/javascript" > 
   
  function OnRowClick() 
  { 
   var firstDataItem = $find("RadGrid1").get_masterTableView().get_dataItems()[0]; 
   var keyValue1 =   firstDataItem.getDataKeyValue("ProductName"); 
   var keyValues2 =   firstDataItem.getDataKeyValue("ProductID"); 
     alert(keyValue1) 
     alert(keyValues2) 
  } 
</script> 

2. You can hide the Expand/Collapse column of the Grid in the ColumnCreated event.

 CS:
 
 protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e) 
    { 
        if (e.Column is GridExpandColumn) 
        { 
            e.Column.Display = false
        } 
    } 

3. You can refer the following help article which explains on how to access detail tables in the code behind.
