All,

I'm trying to change my SortAsc and SortDesc icons on my grid, and I'm not getting any noticeable change. I create the grid programmatically, so I use the method listed in the documentation. I wired up my ColumnCreated event to the following function:

protected void rgrid_ColumnCreated(object source, GridColumnCreatedEventArgs e)

{

e.Column.SortAscImageUrl = "Grid/Skins/SortAsc.gif";

e.Column.SortDescImageUrl = "Grid/Skins/SortDesc.gif";

}

The result:
Nothing. The default arrows (gray/black up and down arrows) are used no matter what I put in there. My "Grid" directory sits on the same level as the .cs file this function is in. I've tried adding / and ../ in front of the url names, all to no avail.

Any help would be GREATLY appreciated.

Hi Luke,

The following simple demo works as expected on my side. Please compare with your implementation.

<%@ Page Language="C#" %>

<%@ Import Namespace="System.Data" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<script runat="server">

protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

DataTable dt = new DataTable();

DataRow dr;

int colsNum = 4;

int rowsNum = 4;

string colName = "Column";

for (int j = 1; j <= colsNum; j++)

{

dt.Columns.Add(String.Format("{0}{1}", colName, j));

}

for (int i = 1; i <= rowsNum; i++)

{

dr = dt.NewRow();

for (int k = 1; k <= colsNum; k++)

{

dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2}", colName, k, i);

}

dt.Rows.Add(dr);

}

(sender as RadGrid).DataSource = dt;

}

protected void RadGrid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

{

e.Column.SortAscImageUrl = "~/grid_images/Delete.gif";

e.Column.SortDescImageUrl = "~/grid_images/AddRecord.gif";

}

</script>
