Data Controls :: Unable To Export GridView To Excel
Feb 21, 2014
I'm unable to Export GridView to Excel. giving Error at GridView1.RenderControl(htw); Error Details: "RegisterForEventValidation can only be called during Render()"
public override void VerifyRenderingInServerForm(System.Web.UI.Control control)
{
/* Verifies that the control is rendered */
}
protected void Button1_Click(object sender, EventArgs e)
I need to export a gridview to excel and am having trouble with the layout. I found a number of good articles that explain the basic mechanics of the export. One simple approach that works is:
Response.Clear() Response.AddHeader("content-disposition", "attachment;filename=FileName.xls") Response.Charset = "" Response.ContentType = "application/vnd.xls" Dim stringWrite As New System.IO.StringWriter() Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite) grdExcelExport.RenderControl(htmlWrite) Response.Write(stringWrite.ToString()) Response.[End]()
My issue is that the gridview that appears on the screen with all of its added rows, hidden columns, and such does not show properly in Excel - the hidden columns from the header now show; there are missing data rows and so forth.
The RowDataBound event adds rows in the Header - these do not make it into Excel. The sql code does a GROUP BY WITH ROLLUP and the last total rows do not show in Excel, although the intermediate ones do. After my first DataBind of the table, I append 5 rows of special summary information which the RowDataBound processes correctly, but none of this goes to Excel.
So my wonderful Gridview on the screen becomes worthless in the transfer. How do I get my highly custom-formatted gridview into Excel??
How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?

I have a gridview that I need to export to Excel. Excel is not installed on the server, but I would like to put a template on the server so that when the user exports the data it will use the template and open the file on the user's local machine.To make things slightly more complex, I need to export the data to Sheet2 because Sheet1 needs to be a graph (thus the need for the template).I cannot use any third party software and I have no ability to modify anything on the server. This is used in a corporate environment on a shared server that I don't have any control over.
