the below code is super fast and got it through searching inside Code project itself
Dim ds As DataSet
ds = New DataSet()
Dim dg As New System.Web.UI.WebControls.DataGrid()
'fill datagrid
da.Fill(ds)
dg.DataSource = ds
dg.DataBind()
'datagrid formatting
dg.Font.Name = "Verdana"
dg.BorderStyle = System.Web.UI.WebControls.BorderStyle.Solid
dg.HeaderStyle.BackColor = System.Drawing.Color.Blue
dg.HeaderStyle.ForeColor = System.Drawing.Color.White
dg.HeaderStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Center
dg.HeaderStyle.Wrap = False
dg.HeaderStyle.Font.Bold = True
'export to excel
Context.Response.Buffer = True
Context.Response.ClearContent()
Context.Response.ClearHeaders()
Context.Response.ContentType = "application/vnd.ms-excel"
EnableViewState = True
Dim tw As New System.IO.StringWriter()
Dim hw As New System.Web.UI.HtmlTextWriter(tw)
dg.RenderControl(hw)
Context.Response.Write(Now)
Context.Response.Write(tw.ToString())
Context.Response.Flush()
Context.Response.Close()
Context.Response.End()
da.Dispose()
da = Nothing
ds.Dispose()
ds = Nothing
con.Close()
con.Dispose()
con = Nothing

If you are using ASP.NET 2.0, replace onclick with onclientclick. If your version is 1.1, the go with attributes.add("OnClick","function();").
If you specify onclick like what you specified now, ASP.NET will think it is a server side function and will look for it's references that leads to the error.

Your best solution is here.
Use OnClientClick instead of OnClick event
i.e
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return validation();" />
and Javascript
<script language="javascript" type="text/javascript">
function validation()
{
if(document.Form1.textbox1.value=="")
{
alert("please fill it");
return false;
}
}
</script>

HI.
U can use
Button.Attributes.Add("onClick","function();");
but out of Ispostback
U can also call javascript function by onclientClick event in source code
If u call by Onclientclick plz remove code from codebehind file.

execute SQL statement.....and fill a DataSet with your information
if you use ACCESS as a database and VB.NET as your language then follow...
Dim mySql AS String="SELECT * FROM myTable"<br />
<br />
Dim ds As DataSet<br />
Dim da As OleDbDataAdapter<br />
<br />
da = New OleDbDataAdapter(mySql, myConnection)<br />
ds = New DataSet<br />
da.Fill(ds)<br />
<br />
DataGrid1.DataSource=ds

well! isnt there any need to use data reader??
well my code is
//connection as conn
strQuery = " SELECT * FROM table";
SqlCommand com1 = new SqlCommand(strQuery, conn);
DataSet ds=new DataSet();
SqlDataAdapter da=new SqlDataAdapter();
SqlDataReader dr = com1.ExecuteReader();
if (dr.Read())
{
da.Fill(ds,"table");
}
its not working i mean data is not displaying in the grid..and the exception that is shown is
"The SelectCommand property has not been initialized before calling 'Fill'."

why are u using datareader and dataset simultaneously???
follow this...
'1. Create a connection<br />
Dim myConnection as New SqlConnection(<br />
ConfigurationSettings.AppSettings("connectionString"))<br />
<br />
'2. Create the command object, passing in the SQL string<br />
Const strSQL as String = "SELECT * FROM myTable"<br />
Dim myCommand as New SqlCommand(strSQL, myConnection)<br />
<br />
'Set the datagrid's datasource to the datareader and databind<br />
myConnection.Open()<br />
DataGrid1.DataSource = myCommand.ExecuteReader(<br />
CommandBehavior.CloseConnection)<br />
DataGrid1.DataBind()
but keep in mind
A datareader is a read-only object. If you need to edit and update changes you need to use a dataset.
