sorry let me explain my scenrio, I have 2 type of display in dropdown as Horizontal and vertical. if select horizontal it is normal gridview but on selecting vertical, i'm converting Rows into column to get vertical display in Gridview, the datasource is dynamic dataset. so in this mode, i already tried the paging as like ur idea by assuming the Dropdown(page dropdown selecting 5 0r 10 etc...)value as i in a forloop, but i get an error..
The code i wrote was
for (i=0;i<=int.Parse(drppagelist.SelectedValue.ToString());i++)
{
GridView1.Column[i].Visible=True;
}
but error comes as value cannot be 0 or less than index range...

I understand your problem. Please follow up my previous post.
Dear, Right now you are facing a little bit logical issues like index of range, this is not a major problem just try it you will resolve it.

You should bind your data grid to it's data source in prerender, not in page load. Then, it will occur after any event handlers, and you should see the results.

Iam getting the error with the following lines...
DataRow newRow = myDataTable.NewRow();
newRow["ProductID"] = rows["ProductID"];
newRow["ProductName"] = rows["ProductName"];
myDataTable.Rows.Add[newRow];

I noticed that the Column "ProductID" (DataColumn productIDColumn = new DataColumn("ProductID") did not specify the Data type.
I think your data base returning ProductID as int type.
So you can resolve this prob lem in two way
(1) newRow["ProductID"] = rows["ProductID"].ToString();
OR
(2)Also specify the Data type as int, When you are creating the column
DataColumn productIDColumn = new DataColumn("ProductID")

Hi,
I am using RegisterStartupScript in a user control but it is not running the code.
Can you do this from a user control?
msg = "Invalid date entered for 'to' field."
script = "<script>"
script += "alert(""" & msg & """);"
script += "</script>"
Me.Page.RegisterStartupScript("script", script)

Try this One:
msg = "Invalid date entered for 'to' field."
script = ""
script += <b>"alert('" & msg & "');"</b>
script += ""
