将gridview导出到pdf asp.net C＃Web表单

Question

I have some problems to export gridview to pdf.

First , it shows error message

Control 'ContentPlaceHolder1_GVAttendance' of type 'GridView' must be placed inside a form tag with runat=server.

and then I tried to googling and find these codes,

public override void VerifyRenderingInServerForm(Control control)
    {
        /* Verifies that the control is rendered */
    }

but it show error message again

Error 5 'My.Project.Control' is a 'namespace' but is used like a 'type'

How can i fix it?

Answer 1

Try Replacing the above code like this

public override void VerifyRenderingInServerForm(System.Web.UI.Control control)
    {
        /* Verifies that the control is rendered */
    }

Hope this works.
