possible to change the webcontrol type?

Is that possible to change the WebControls type?

I have a control. With spaghetti code, I can change to either textbox or label. but no clue how to do it in .NET. anyone?

 

[jbenson001]

As far as I know, you can't!

 

[ca8msm]

Can you explain further? That doesn't make any sense to me.

You can't say, take a textbox, now make it a label. There is not conversion possible for that. Is that what you are trying to do?

 

[g2000]

yeah.. jbenson001.. sort of.. but since both control belongs to System.Web.UI.WebControls namespace.

So, I would like .. instead of
<asp:TextBox ... > or <asp:Label ... >

Can I <asp:WebControls ... > ? And set the specific type in
Page_Load or Page_PreRender ???

You can have your own custom control that renders either a child Label or TextBox based on some property, but there's no native control to do either/or.

Within a DataGrid or other tempated control, you can also tweak the item templates to conditionally show Labels or Textboxes.

You'd want to add a PlaceHolder control to the spot you want to conditionally display the TextBox/Label, then conditionally add either to the PlaceHolder's child controls in Page_Load.

 

[jbenson001]

Sounds like BoulderBum is suggesting adding dynamic controls at run time. Is this what you want to do? If so, add them in the Page_Init event.

 

[BoulderBum]

That's assuming he knows the condition that determines the control type by Page_Init.

 

[jbenson001]

That is true...

 

[BoulderBum]

While I'm thinking about it, another popular (though less efficient) alternative is to add a TextBox and Label side-by-side then set the visibility of the controls conditionally.
