打开URL并从代码隐藏处预填充ASPX页面中的文本框

Question

So what I'm doing is a little different than this:

Access a control's property in an aspx page from another aspx page

because what I'm trying to do is "push" a value forward to the next page rather than "pull" it from the previous page.

What I need to do is open a new page from within an Intranet website application (actually, the page will have been previously used by the user) and pre-fill a textbox.

Can this be done? I'm currently forwarding to the new page using:

String SUrl = "frmAuditSearch.aspx";
Server.Transfer(SUrl, true);

What I also need to do is fill a textbox called txtAuditID on frmAuditSearch.aspx with the AuditID from the current page I'm on.

And yes, I know I can use something like:

String SUrl = "frmAuditSearch.aspx?AuditID = '" + MyAuditID + "'";
Server.Transfer(SUrl, true);

but I'm trying to avoid that because most of the time there's no AuditID and that'd require tinkering with too much code.

Answer 1

Sounds like you'd want to fill the text box with something like this.

txtAuditID.Text = (Request["AuditID"] ?? String.Empty).ToString().

This allows the absence of the parameter if needed
