Call function in user control placed in placeholder?

[hpl]

I have attached a project which contain a webform including a placeholder. The placeholder is loaded with a user control. How do I activate a function in the user control from the webform?

[Magiaus]

((UserControlClass)PlaceHolder.FindControl("UserControlID")).Method(); //C#

[hpl]

((UserControlClass)PlaceHolder.FindControl("UserControlID")).Method(); //C#
Great, I'm using VB, but it must be almost the same. I will try that, otherwise I'll get back :-)

My palceholder is named plh1. When I apply this code
plh1.FindControl("Cond1Abs.ascx")
I'm not able to apply the function SetLanguage, that I want to call for the Cond1Abs.ascx? What am I doing wrong?
:confused:

try
vb
Ctype(plh1.FindControl("Cond1Abs"),Cond1Abs).Method()
in C# it'll be like this (as in Magiaus earlier post)
((Cond1Abs)plh1.FindControl("Cond1Abs")).method();


Hope this helps.

Still it returns

Object reference not set to an instance of an object.


But maybe I'm doing something wrong. I have attached the entire project in my first thread, if youn can make it work, please let me know.

You have to look for it by it's ID, not the file name. Make sure you are using the ID. I see in your post above you have the . ascx as part of your call to FindControl. The .ascx should not be there.

I looked at your code. CType(PlaceHolder1.FindControl("WU1"), WebUserControl1).SomeText()

I looked at your code. CType(PlaceHolder1.FindControl("WU1"), WebUserControl1).SomeText()

Hello Magiaus, thanks for your reply.
Is the code working in the code, I have attatched? I still got the error when I implement the code:

CType(PlaceHolder1.FindControl("WU1"), WebUserControl1).SomeText()

I don't know I didn't actually run your code or change it up any. I basicly just looked at it and looked at how you cast in VB.Net.

I don't know that much about VB.Net anymore. I started C# about 2 years ago and I refuse to go back to VB.Net and have subsequently erased all information regarding it....

If you have MSDN I recomend looking at Placeholder and it's implemetation of FindControl in your MSDN. Also I've never used a PlaceHolder I always use a Panel.
