I am using this code FileUpload2.PostedFile.SaveAs(Server.MapPath("~\\Images\\") + "Image" + txtRefNumber.Text + ".jpg"); to save images in host but it doesn't save image on host.

What does it mean ? Are you getting any error ? or what ?
You are talking about Hosting on IIS or Running your Application From Visual Studio ?

Yes ! That's why I asked you the question, what is the problem if you are hosting on server, you have to give Write Access permission to that folder where you are uploadinf the file.

Always rememebr this rule of thumb:
Everyapplication can have one and only one Main function.
Search in your code, it looks that there are multiple main functions are defined.

This has nothing at all to do with ASP.NET. You want the C# forum. You should work through a basic book rather than trying to copy code off the web.

It is not working. there are more than one textboxes and user can enter value more than one textboxes according to colmuns
|
|
|

You can change filter expression for Select of dataset as per our values.
|
|
|
|
|
But it is giving error object refrence is no set an instance in secondline while colmun is ok and also creare memory for dataset
DataRow[] R;
R =ds.Tables["tmp"].Select("cityname ='" + TextBox6.Text + "'");//Error
GridView1.DataSource = R;
GridView1.DataBind();
