help with button to open new window

Mar 14 2008 9:15 AM

i have an ecport to excel button that i need to have open in a new window with paging turned off so that the export will fill all the results from my datagrid.

here is my code

[code]

private void BtnExport_Click(object sender, System.EventArgs e)
{

Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
this.EnableViewState = false;

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
gridPhysician.AllowPaging= false;

this.ClearControls(gridPhysician);
gridPhysician.RenderControl(oHtmlTextWriter);

Response.Write(oStringWriter.ToString());

Response.End();


}
private void ClearControls(Control ctrl)
{
for (int i=ctrl.Controls.Count -1; i>=0; i--)
{
ClearControls(ctrl.Controls[i]);
}

if (!(ctrl is TableCell))
{
if (ctrl.GetType().GetProperty("SelectedItem") != null)
{
LiteralControl literal = new LiteralControl();
ctrl.Parent.Controls.Add(literal);
try
{
literal.Text = (string)ctrl.GetType().GetProperty("SelectedItem").GetValue(ctrl,null);
}
catch

{

}

ctrl.Parent.Controls.Remove(ctrl);
}

else

if (ctrl.GetType().GetProperty("Text") != null)
{
LiteralControl literal = new LiteralControl();
ctrl.Parent.Controls.Add(literal);
literal.Text = (string)ctrl.GetType().GetProperty("Text").GetValue(ctrl,null);
ctrl.Parent.Controls.Remove(ctrl);
}
}
return;

}

[/code]

<asp:Button id="Button1" runat="server" Text="Export to Excel"
OnClick="BtnExport_Click" ></asp:Button>
