creating my own TextBox

[George Ter-Saakov]

I am adding some functionality to HtmlInputText so i derived my class from
it.
The problem is when i switch page to desing mode the VS shows an error and
do not render control.

Unable to cast object of type
'System.Web.UI.Design.HtmlIntrinsicControlDesigner' to type
'System.Web.UI.Design.ControlDesigner'

Not sure how to fix it and make it work in design time
Here is how my class looks like
public class GTextBox : System.Web.UI.HtmlControls.HtmlInputText

{

}

PS: It works fine in a runtime.

George.

Hi, George.

You will find these pointers to be of interest :

http://www.eggheadcafe.com/articles/pfc/extendservercontrol.asp

Unfortunately no.
In that article they inherit TextBox not HtmlInputText
And TextBox does not have that problem. Only inheritance from HtmlInputText
has problem.

So still looking for an answer.

I replied to your question about "creating my own Textbox",
which the article I posted addresses quite coherently.

Maybe you should have used the subject :

"creating my own HtmlInputText" ?

;-)

Well, you right, I should have.
I used TextBox in subject line with actual meaning and not referring to the
C# class.

I am reposting with correct subject line.

Thanks
George.
