Suppose myCombo is the name of your dynamically created control....then add a Event handler like this....

myCombo .SelectedIndexChanged += new System.EventHandler(this.cmbDynamicNameCombo_SelectedIndexChanged);

Now put your code in cmbDynamicNameCombo_SelectedIndexChanged

{
MemoryStream oStream; // using System.IO
oStream = (MemoryStream)
report.ExportToStream(
CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
Response.Clear();

GridView does not have direct functionality to export data into Excel, so you would need to add extra efforts on your side to do this job.
There are several ways to export data into Excel and preserve format

1. Use Jet OLEDB Provider. You need to create INSERT SQL statements and loop through the rows of the grid to insert records one by one. But in this case you need to convert your column from numeric data type to string one.

2. Use Microsoft Office Tools for .NET. This way is slower, but gives you more functionality and allows formatting of the data. It allows you to control your output, but could be very slow and you need to pay attention to releasing all the resources associated with it, because it is COM-based.

3. Write code that stores data into CSV or HTML. Those formats recognized by Excel and should preserve formatting

4. Use third party components like Ajax, that could provide desired functionality

Hi Satips,

Thanks for the reply.
I got some code from Google.Its working fine.The only thing is that I need to save it on the server and filename should be given by me not by user.Following is the code:
On Export Button Click:

Dim attachment As String = "attachment; filename=Contacts.xls"
Response.ClearContent()
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/ms-excel"
Dim sw As StringWriter = New StringWriter()
Dim htw As HtmlTextWriter = New HtmlTextWriter(sw)
gvExport.RenderControl(htw)
Response.Write(sw.ToString())
Response.End()

This throws HttpException so I need to add this:

Public Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)

End Sub

Now I just need to save it on server.

Can u please tell how do I do??

Thanks in advance...
