user-controls

问题 Let's say I have an a .ascx user control. How do I get its HTML markup into a string? 回答1: Once you use the LoadControl() method to get it into a page, you can can get the HTML by calling the Render() method on it. It requires an HtmlTextWriter to write to, but it's fairly straightforward to construct: var userControl = (userControlType)Page.LoadControl( ....ascx); StringBuilder sb = new StringBuilder(); StringWriter SW = new StringWriter(SB); HtmlTextWriter htw = new HtmlTextWriter(new

问题 I want to forward the mouse scroll event from a control to its direct parent (which is also UserControl in my case). How is this possible? Edit The control is added to a control that is scrollable. Like a memo-edit for example. When the user scrolls in the memo-control, the memo-control is scrolled (!) But when the user scrolls on top of the custom control the event is not forwared to the parent control and the memo-control does not scroll. 来源： https://stackoverflow.com/questions/10041923

问题 I need to add a close "x" button in the upper left corner of a UserControl. I'd like that button have similar style as a usual Winforms close button (Blue in XP style, etc).

问题 I'm using UserControl s inside a WinForm to display data. I'm also using the command pattern so that the UserControl registers a (weak) event and does stuff when the command is triggered. On a WinForm I can unregister the events in the Close event. However there's no such event on a UserControl . I hooked up the events I thought would be fired when the UserControl is no longer in the display stack but could find nothing useful. To get by I check if the Parent is null and that worked for most
