Hi all

I'm designing a page around web parts (which I'm completely new to) and I've got a question that feels kind of silly to ask.

The way my project is set up is that I named a .ascx file addPart.ascx and this file contains a button and a textbox (named txtAdd). Then, on another form (mainForm.aspx), I added a webpartzone and added my addPart.ascx to the zone. What I want to do is modify the txtAdd.Text property when the page loads, but I can't access it from mainForm.vb as the text box is declared in the addPart.ascx file.

Pushing the button isn't a problem as I can  just double click the button on the addPart.ascx file and write the needed code there.

If anyone could give me a hand I'd really appreciate it, thanks.

Here's an example:

VB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    If WebPartManager1.WebParts.Count > 0 Then
        Dim wp As WebPart = DirectCast(WebPartManager1.WebParts("WebUserControl1"), WebPart)
        Dim tb As TextBox = DirectCast(wp.Controls(0).FindControl("TextBox1"), TextBox)
        If tb IsNot Nothing Then
            tb.Text = "Hello ASPNET!"
        End If
    End If
End Sub

C#

 protected void Page_Load(object sender, EventArgs e)
    {
        if (WebPartManager1.WebParts.Count > 0)
        {
            WebPart wp = (WebPart)WebPartManager1.WebParts["WebUserControl1"];
            TextBox tb = (TextBox)wp.Controls[0].FindControl("TextBox1");
            if (tb != null)
            {
                tb.Text = "Hello ASPNET!";
            }
        } 
    }

 Perfect, thanks very much!
