Question

Alright, I am trying to accomplish this: When a user clicks a button that is on a ascx web user control with text boses, it first displays a DIV that is hidden, this div contains a ascx web user control. Basically I want that web user control to grab what they typed in the boxes on the first web user control, and then apply to a SQL search from what the users type in the text boxes on the first page. Is this possible or do I need to rethink my strategy on this? I am programming in c# for the SQL statements.

It is possible.

You can define properties of the control which accepts the text input, and expose the values using direct field access, variables, or session variables; you can then use FindControl from within the newly displayed control, and, if found, utilise the now exposed properties to gather the values required.

For instance, your input control code-behind might look something like this:

partial class MyControl : UserControl
{
    public string MyFieldValue
    {
        get { return MyFieldTextBox.Text; }
    }
}

And in the next control, to use it, a little like this:

partial class MyControl : UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
        var myControl = Page.FindControl("MyControlInstanceName") as MyControl;
        if (myControl != null)
        {
            var myFieldValue = myControl.MyFieldValue;
        }
    }
}
