DetailTables

[Sridevi]

Hi,
when we are using client side binding of DetailTables in RaDgrid following issues we found

1.Unable toassign multiple datakeynames for ClientDataKeyNames, when we tried its throwing error
2. Unable to Hide and show the Expand and Collpase buttons on RadGrid1_ItemDataBound
3. Unable to find the control in the detailtables

Thanks,
Sridevi.

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.
