Dynamically adding in User Controls

Re: Dynamically adding in User Controls

Hi,

The way I do this:

Don't put any register tag prefixes.
Put a placeholder where you want the control to appear.
In your code behind load the control you want, i.e.:

Dim MyControl As New Control
MyControl = LoadControl("Tr avelClinicSearc h.ascx")
plcDatabases.Co ntrols.Add(MyCo ntrol)

Where plcDatabases is the name of the placeholder. Obviously, the
control name can be a variable.

Hope this helps.

Re: Dynamically adding in User Controls

That was what I was looking for.

I wanted to be able to load a control depending on settings in my session
variables and this would allow me to do that.

Thanks,

Tom
