ASP.NET FISH: access

I have a user control that is basically a login dialogue.
If I add the user control to webpage1, can I access the
properties directly from C# codebehind, or do I have to
access the properties from HTML behind webpage1.

Thanks in advance. PeteWebpage1 is a standard ASP.NET webform which contains the
user control. I know I can access properties of the user
control via the HTML of webpage1 i.e.
<uc1:LoginUserControl id="LoginUserControl1"
property1="Hello" property2="Goodbye"
runat="server"></uc1:LoginUserControl
but is it possible to access the properties from webpage1
code behind page.

Hope this is a little clearer.
Pete.

Yes It is possible. Here is the code to do it.

Dim _myControl As Control = Page.FindControl("UserControlName")
Dim _myControlType As Type = _myControl.GetType()
Dim _myControl_Property As PropertyInfo =
_myControlType.GetProperty("PROPERTYNAME")

sTemp = _myControl_Property.GetValue(_myControl, Nothing)

Hope this helps.

Your CodeBehind Page should have a reference to the control if you used the
tag you mentioned in your reply. You can therefore access the properties of
the object in your CodeBehind (using its' ID) without any problem.

I misunderstood your question, and neglected to observe that you were
talking about a User Control instead of a Server Control. Handling the User
Control from your CodeBehind is a bit trickier than a Server Control. The
following MSDN article should help:

Hi. I have the following HTML Control and I want to access the value in my asp.net code.

<INPUT ID="hdnFPrintNA" runat=server STYLE="Z-INDEX: 163; LEFT: 165px; WIDTH: 38px; POSITION: absolute; TOP: 5px; HEIGHT: 22px" TYPE="hidden" SIZE="1">
--------------
When the user presses my Server control button to clear the screen, I would like to clear the hidden text field as well. The below doesn't work.

Private Sub btnClear_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClear.Click

hdnFPrintNA.Text = ""

End Sub
-------------
I have been searching this site to try and find the answer but I am only getting confused. Can any one point me in the right direction and tell me how to solve this problem?

ThanksI think it should read

hdnFPrintNA.value =""
Try using "hdnFPrintNA.Value" instead. And also remember to define your Html Control as:

'System.Web.UI.HtmlControls.HtmlInputHidden'
Thank you both for your help. It works now. :)
