.NET Forum / ASP.NET / Building Controls / March 2005High-level question about ASP.NET web controls..
I'm a bit of a noob when it comes to web controls... What I want to do, is create web control that appears in the toolbox, that one could drag onto a web page - and you'd see the actual control (e.g. what it will look like on the resultant web page - much like how the datagrid looks). If I use a "user control", it puts that grey box describing the control, and you need to imagine what it will look like (yipee!)! If I create a seperate "web control" project, and it creates the default "WebCustomControl1.cs" - that adds to the toolbox, but just displays text. And after scouring the net, looks like you'd need to manually create your controls in text, which doesn't sound right. Shouldn't I be able to WYSIWYG a control (and add my code behind it) and make that available via the toolbox? The main thing I want is to see it in design-time, and be able to manipulate the public properties... What am I missing? Thanks! > I'm a bit of a noob when it comes to web controls...

You need to implement the "text" as html in the web control and you also may need to look into Designers for your web control. Try the samples that come with the .Net SDK and the MSDN Library for more information about how to do both :) Mythran Thanks for the response... But what I'm not "getting" - is that the whole point of writing a control, is it likely needs to do something a bit complicated or complex. So if there were EVER a time, there should be a visual editor for laying something out, it would be THAT!! :-) I've been through the samples and MSDN and haven't found any reference to a designer for a web control - do you have a link perhaps?? Thanks again! >> I'm a bit of a noob when it comes to web controls...

Thanks again! RCS, Ok, then...in the MSDN Library, look up ControlDesigner class (System.Web.UI.Design) [under Index in MSDN]. Also, for some examples, check out the following MSDN link (in the MSDN library): ms-help://MS.MSDNQTR.2003FEB.1033/cpguide/html/cpconhtmldesignersample.htm and found on goolge: http://aspalliance.com/articleViewer.aspx?aId=436&pId=-1 The above samples are extremely simple controls/designers. Control designers used with Web Controls can create powerful web control design-time support for your web controls. For more design-time support, check out TypeConverter and UI Type Editors. Hope this helps ;) Mythran This has been a pretty frustrating day - I can't believe this, is this difficult. But thanks again for your help!! >> Thanks for the response... >> [quoted text clipped - 27 lines] > > Mythran User Controls allow you to use the designer to build them and they're typically only used within a single project. There is no toolbox support for them. Custom and Composite controls are packaged as DLLs and as you've seen have no designer support, as they create all of their child controls in code. They are built as a DLLs to deter modifications to the code/layout and this is what a third party control dev would build. These do have toolbox support/integration for that purpose -- these are meant for reuase across different applications. -Brock DevelopMentor http://staff.develop.com/ballen > I'm a bit of a noob when it comes to web controls...

Control creation is a deep topic. I have a lot of information about the creation of web controls on my web site. I think you could learn some things there.  SignatureI hope this helps, Steve C.
