.NET Forum / ASP.NET / Building Controls / February 2006Setting web custom control properties at design time
I am developing a Web custom control whose properties (such as text) I would like to map to other control properties (such as textbox1.text) or variables of the web form at design time. Is this possible?  SignatureNK Hi, yes it is. One way is to write a composite server control. Here's a sample http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cp concompositecontrolsample.asp And here's one good article: http://aspalliance.com/359 If you use ASp.NET 2.0 see: http://dotnet.sys-con.com/read/171169.htm (with ASP.NET 2.0 you'd inherit directly from CompositeControl base class) SignatureTeemu Keiski ASP.NET MVP, AspInsider Finland, EU http://blogs.aspadvice.com/joteke >I am developing a Web custom control whose properties (such as text) I >would > like to map to other control properties (such as textbox1.text) or > variables > of the web form at design time. Is this possible? Thanks Teemu. But I am not looking to access the child controls within the composite control. This is definitely possible as you indicated. What I am looking for is, I have a, say composite control with property say Text. Now when a developer uses my control and tries to assign the Text property through Property window, I would like to show him/her, the other Textbox names in that web form. Say the developer has assigned (mapped) to Textbox1, at runtime, the Text property of the composite control should take the text value from Textbox1. Is such a mapping possible? SignatureNK > Hi, > [quoted text clipped - 13 lines] > > variables > > of the web form at design time. Is this possible? Hi, basically providing a list of controls can be done with a custom type converter, when it would pick IDs of other controls and set such into the property.Is that what you mean? For example similar when you set ControlToValidate of a validator control. it shows you list of all controls having ValidationProperty attribute applied. Yes, such is done with a custom type copnverter.

Is this possible? Thanks Teemu. But I am not looking to set the property value from child controls of the composite control. This is very much possible as you indicated. What I am trying to do is, say, I have a composite control with a property Text. Now when a developer uses my control, and when he/she tries to assign the Text property through the property window, I would like to show him a list which has names of other Textboxes in the Web form. Now say, the developer has assigned (mapped) it to Textbox1, then at runtime, the Text property of Textbox1 should be assigned to the Text property of the composite control, during initialization of the Web form.
