Anyone who knows how to read error?
-
I was trying to export my gridview to excel.
protected void btnExcel_Click1(object sender, EventArgs e) { Response.Clear(); Response.Buffer = true; Response.ContentType = "application/vnd.xls"; Response.Charset = ""; System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter); dgDisplay.RenderControl(oHtmlTextWriter); Response.Write(oStringWriter.ToString()); Response.End(); } public override void VerifyRenderingInServerForm(Control control) { //base.VerifyRenderingInServerForm(control); }Can someone explain to me what this error means? RegisterForEventValidation can only be called during Render();thanks in advance. Much appreciated.
