• Personalizing complex properties of web controls

  I'd like to personalize complex properties of web controls. For example, say I have a control that inherits from TreeView with nodes defined. I'd like to make the nodes persistable, because I'd like to put my control in a DeclarativeCatalogPart in a CatalogZone. When I add the control from the catalog, I'd like the nodes entered at design time available at run time. I'd appreciate any ideas on how I can do this. Thanks, Sentha

• Re: TreeView does not respect Width/Height settings; does not display scrollbars

  Thank you so much!! That works. For my control that inherits from TreeView, I overrode the following methods: public override void RenderBeginTag(HtmlTextWriter writer) { writer.Write(String.Format("\n<div style='height:{0}px;width:{1}px;overflow:scroll;'>", Height.Value, Width.Value)); } public override void RenderEndTag(HtmlTextWriter writer) { writer.Write("\n</div>"); }

• TreeView does not respect Width/Height settings; does not display scrollbars

  The TreeView control does not seem to respect the Width and Height properties and always stretches to display all the nodes. How can I get it to use scroll bars if all of the content cannot be displayed in the area specified by the Width and Height properties? To reproduce: Add a TreeView control to your webform, set it's width property to say 50 px, then add a node with a really long Text property. I'm creating a control that inherits from the TreeView control, so I welcome any suggestions for solving

• Re: Getting TreeView to postback when node is checked/unchecked

  This works!! Thanks!!! I'm writing a control that inherits from TreeView. I can set the "onclick" attribute of the control to the name of a javascript function that I render like this: Attributes["onclick"] = "javascript:postbackOnCheck(event)"; My javascript function reads like this for netscape interoperability: function postbackOnCheck(e) { var isNav = (window.navigator.appName.toLowerCase().indexOf("netscape")>=0); var o; if (isNav && e != null

• Re: Getting TreeView to postback when node is checked/unchecked

  Thank you both for the suggestions! This would be useful if I can figure out how to do this programmatically from a server control. I have a server control inheriting from TreeView. I want to enable postbacks on it when checked. I can render the javascript function, etc., but I can't figure out a way to set the "onclick" event to the javascript function. I'd appreciate any suggestions. Thanks, Sentha

• Getting TreeView to postback when node is checked/unchecked

  Hi, How can I get TreeView to postback whenever a node with a checkbox is checked/unchecked? With the IE webcontrols, I could do this with the AutoPostBack property. With the Whidbey TreeView, I don't see a similar property. Thanks, Sentha Sivabalan
