Radgrid column filters

[Tim]

I'm using RadGrid for an application.

The rendered grid has filters on top of each column.  When I supply a value and select any filter from the dropdown (e.g. contains, Begins with, etc) the form posts back to the server.

I'm trying to determine the event handler for this postback.

Please advise.

 Thank you,

Hi Tim,

​You can access the filter value using the following approach:

Copy Code

Copy Code

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.FilterCommandName)
    {
        string colName = (e.CommandArgument as Pair).Second.ToString();
        if (colName == "ShipCountry")
        {
            string value = e.Item.OwnerTableView.GetColumn(colName).CurrentFilterValue;
        }
    }
}

Or using a similar implementation as the following:

Copy Code

Copy Code

Copy Code

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    foreach (GridColumn col in RadGrid1.MasterTableView.RenderColumns)
    {
        string filterValue = col.CurrentFilterValue;
        GridKnownFunction filterFunction = col.CurrentFilterFunction;

        if (!string.IsNullOrEmpty(filterValue))
        {
            string result = col.UniqueName + ": " + filterValue;
        }
    }
}

This way you can access the filter value defined by the user and use it to execute any custom logic.

Hope this helps.
