RadGrid Sort Programatically

[Jagat]

Hi,

How do I get the columnName/UniqueName of the field that has been clicked in order to sort the grid by that column?

Thank you !!

Hi,

I guess you want to get the column UniqueName when the column is sorted. Please take a look into the following code snippet.

C#:

protected void RadGrid1_SortCommand(object sender, GridSortCommandEventArgs e)
{
    string datafield = e.SortExpression;  //you will get the column Datafield
    foreach(GridColumn col in RadGrid1.MasterTableView.RenderColumns)
    {
        if (col is GridBoundColumn && (col as GridBoundColumn).DataField == e.SortExpression)
        {
            string uniquename = col.UniqueName;  //you will get the column uniqueName(of bound column for example)
        }

    }
}

Thanks,
Shinu.

Hi,

You can set the sort expression programmatically as shown below.
C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
 GridSortExpression expression = new GridSortExpression();
 expression.FieldName = "UniqueName";
 expression.SortOrder = GridSortOrder.Ascending;
 RadGrid1.MasterTableView.SortExpressions.AddSortExpression(expression);
 RadGrid1.MasterTableView.Rebind();
}

Thanks,
Shinu.
