Hi guys,

I can export data to excel from ASP.Net GridView.

but I cann't export data to excel from Asp.net Infragistics WebDataGrid.

my Code is Given below,


private void Excel_Export()
{

Response.Clear();

Response.Buffer = true;

Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls");

Response.Charset = "";

Response.ContentType = "application/vnd.ms-excel";

StringWriter sw = new StringWriter();

HtmlTextWriter hw = new HtmlTextWriter(sw);

// GridView1.AllowPaging = false;
//GridView1.DataBind();


wdgrid.DataBind();

for (int i = 0; i < wdgrid.Rows.Count; i++)
{
// Infragistics.Web.UI.
GridRecord row = wdgrid.Rows[i];
row.Attributes.Add("class", "textmode");

}

wdgrid.RenderControl(hw);
// GridView1.RenderControl(hw);
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

}


it returns below error,

Argument Exception wasunhandled by user code

Script control 'wdgrid' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
