| Well... I've posted a couple of pretty simple (dare I say dumb) questions recently, thanks Vandana for answering the last one. Hopefully this one is a little less of a flop !!

| ASPFriends.com 'aspngcontrolscs' list |
| I had struggled with the following issue for a while and have received an answer from Microsoft (very quickly too!) I though you might appreciate the knowledge. A ListBox control restores its Items list automatically on Post Back when that control is declared directly in the ASP.NET code. So you can write: script protected void Page Load() { if (!IsPostBack) { MyList.Items.Add("Item1"); MyList.Ite... |

| Capturing postback events in a custom control rendering <Input type=image> (2 replies) |
| ASPFriends.com 'aspngcontrolscs' list |
| Hi all.... The code below doesn't work, RaisePostBackEvent never gets called. If I change the type from image to submit it works fine, there's only a problem when the type is set to image. I've also tried implementing the IPostBackDataHandler interface instead, also with no luck. I'm just not understanding whats going on here as the Webcontrols.Imagebutton renders almost identical html and it seem... |

| I have a custom control that inherits from the datagrid. As part of my control, I add an EditCommandColumn in my controls Init event (I also set a bunch of default properties in my controls constructor). If I just leave all of the default properties alone, everything works fine.

| Hello, people: I'd like to implement a control called, for instance, "ParentControl", which in turn has a property called "ChildControls" that represents a collection (called "ChildControlCollection") of a control called "ChildControl", so that, when I add ChildControls to the ParentControl's ChildControls property through the VS.NET dialog box, those ChildControls appear as nested tags between th... |

| I have a control that wraps around other controls: CN:ParentControl runat "Server" SUB:ChildControl runat "Server" / SUB:ChildControl runat "Server" / SUB:ChildControl runat "Server" / /CN:ParentControl Under certain conditions in ParentControl I set its visibility to false, which of course hides the other three controls. This is the desired effect. When I look at the control tree using Trace, I c... |
