Asp.net: response.redirect not working

Question

I have a .aspx form in which I have an object for selecting a list with a list that I retrieve from a DB table.

The submit button, clicking on which raises questions related to this object, in the form of a grid.

I do this by calling the FillGrid () function in a button click event.

I also have a pageview for my gridview in which FillGrid () is called again.

In my FillGrid () function, I used a catch try block. If an error occurs, I want to redirect the page to the error page using Response.Redirect (). The problem is that this response.redirect is not working. One reason for this is that when you click a button, the form is published twice. Because after reaching the response.redirect reaction, the stream returns to pressing the button where FillGrid () is called.

How can i solve this? Or just saying how can I prevent duplicate form posting?

Although you can use Server.Transfer to get around this, I would recommend using the error forwarding built into ASP.NET. See this page for more information on what is available and how to use them.
