Hi,
I am trying to export gridview data to excel. It is working fine except the first row in the excel is blank.
The code i used for the excel is shown below:
HttpContext.Current.Response.Clear();
Response.ClearContent();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=GrpFile.xls");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
HtmlForm frm = new HtmlForm();
gvCampGrp.Parent.Controls.Add(frm);
frm.Attributes["runat"] = "server";
frm.Controls.Add(gvCampGrp);
frm.RenderControl(hw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
I also included the following code.
public override void VerifyRenderingInServerForm(Control control)
{
return;
}
How to export data to excel without making its first row empty?
Please help.

i removed the htmlform code from the section and now it worked fine.
HttpContext.Current.Response.Clear();
Response.ClearContent();
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=GrpFile.xls");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
gvCampGrp.RenderControl(hw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
and
public override void VerifyRenderingInServerForm(Control control)
{
return;
}

Create a transparent[^] form, and make sure that the border isn't transparent.

but that transparent form will recieve click events rather than desktop itself, right?

Wrong. Alternatively, you can set a specific color to become transparent.
using System;
using System.Drawing;
using System.Windows.Forms;
using System.Collections.Generic;
static class Program
{
public static void Main()
{
using (var f = new Form())
{
var b = new Button();
b.Text = "Hello world";
f.Controls.Add(b);
f.BackColor = Color.Red;
f.TransparencyKey = Color.Red;
f.AllowTransparency = true;
f.WindowState = FormWindowState.Maximized;
f.ShowDialog();
}
}
}

well using ur technique if i draw something on form that is red, it wont appear.
|

|

I'd recommend using a different transparency-key than red. Pick one that's not in use yet.

i am making an app that will display lots of light bulbs of different colors, so i dont think this transparency key thing will work.
|
|
|
|

Anytime there is a completely transparent item in WPF it is basically invisibile. I often will have a minimum transparency when I actually want to be able to interact with a control.

You are looking at widget development.
Developing a gadget for Windows Sidebar[^] should help you get started.
This will help you create a widget which can run in the background while you can continue and work on the desktop.

If I were you, I'd start by downloading JulMar's ATAPI[^] source. This wraps the unmanaged TAPI 2.x functionality. Then it's a simple matter of hooking into the TE_CALLINFOCHANGE event in the Tapi class.

Hi all,
I've a strange problem on my app.
I have one app that works fine and uses this instruction:
<pre lang="c#"> xlWorkbook = excelApp.Workbooks.Open();
</pre>
This works fine and all is ok.
The problem occurs when I run the .exe from another program, I execute (Process myProcess = Process.Start(myProcessInfo);) and the program start correctly, but crash on the instruction xlWorkbook = excelApp.Workbooks.Open();.
Is very strange because if I run the .exe via command line all works fine... The app that execute the other one run with administrator privileges...
Someone can help me?
Thank you very much!

Is the app used to start your .exe a .Net application? If so, are the framework versions the same? Different framework versions can cause strange effects.
Does the app run from a non-local disk? If so, security mechanisms may cause trouble.
Furthermore, when you call a .exe from some other program, it inherits the environment variables of that other program - also check here for differences.
And of course, different users (administrator vs. "normal" user is equivalent to different users) have different environments.
