[Solved] Identfy request from Refresh button

[Sabyasachi Dechaudhari]

Hi,
   There are cases when the grid is sorted. In that request, i dont want to go to the database.
   How ever, when the refresh button is pressed or the grid is loaded for the first time, I want to go to the database.

   How can i identify the difference between these 2 requests.

Currently the signature of the function is

public

 

static List<Employee> getAllEmployee(string sortExpression)
{..}
comming from object datasource mapped to the grid

 

<asp:ObjectDataSource ID="dsEmployee" runat="server" SelectMethod="getAllEmployee"
        TypeName="Employee" DataObjectTypeName="Employee"
        SortParameterName="sortExpression"></asp:ObjectDataSource>

Hello Sabyasachi,

You can try to handle the ItemCommand event as demonstrated below:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == "RebindGrid")
    {
        ....
    }
    if (e.CommandName == "Sort")
    {
        ....
    }
}
