Hi,

I suppose you are using simple data binding to bind the grid. In order to implement advanced features in RadGrid like editing, paging etc.. make sure that you are using advanced data binding using its NeedDataSource event. Check the following help documentation for more.
Advanced Data-binding (using NeedDataSource event)

hi shinu , Am not using default datasource, the data is fetched from the table dynamically based on the search criteria , how can i use advance datasource in it.. (i.e) On button click based on the search parameters passing i have to load the grid dynamically ...  help me with a eg code..  thnx in advance..

Hi Siva,

To achieve the desired functionality you can try using the following approach:

Attach NeedDataSource event to the RadGrid:

protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
   RadGrid1.DataSource = GridDataSource;
}

Where GridDataSource is a collection of items to which the RadGrid is bound and it is kept into the Session:  

public List<DataSourceType> GridDataSource
{
     get
     {
         if (Session["GridDataSource"] == null)
         {
             Session["GridDataSource"] = new List<DataSourceType>();
         }

         return Session["GridDataSource"] as List<DataSourceType>;
     }
     set
     {
         Session["GridDataSource"] = value;
     }
 }

Here the DataSourceType is the type of the elements fetched from your table. The List<DataSourceType> can be replaced also with DataTable depending on your scenario.
Then on button click you need to assign data to the GridDataSource property and call RadGrid1.Rebind() method:

void button1_Click(object sender, EventArgs e)
{
     GridDataSource = something;
     RadGrid1.Rebind();
}

I hope this helps.
