user-controls

问题 I reference a previous post: Focus lost on partial postback with UserControls inside UpdatePanel where an excellent solution works perfectly for web-page controls within a form. However, I have placed my UC inside a detailsview template-field (for Edit+Insert). The UC contains an UpdatePanel needed to adjust the text-formatting and control's style(s) following the TextChanged event of the UC-textbox (AutoPostback=True) during the Edit-mode and Insert-modes of the DetailsView. As such, when

问题 I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead? Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form. Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the

If IsChecked == true my button shall change its background color to something else and keep this color until IsChecked == false . Here is my DependencyProperty : public static readonly DependencyProperty IsCheckedProperty = DependencyProperty.Register("IsChecked", typeof(bool), typeof(MainMenuButton), new PropertyMetadata(false)); public bool IsChecked { get { return (bool)GetValue(IsCheckedProperty);

问题 I am working on a wizard form framework that will allow me easily create wizard forms. I have a WizardForm form that has a panel on it. My plan is to dynamically load UserControls into this panel on the form. Each UserControl that is loaded onto the form panel must implement certain properties (allowNavigateNext, AllowNAvigate previous etc.). So I have created an interface to enforce that contract so that any custom user control can be used in the wizard as long as it implements that

问题 I have a UserControl for which I think I'm initializing some of the members: // MyUserControl.cs using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms; namespace MyNamespace { public partial class MyUserControl : UserControl { private string m_myString; private int m_myInt; public string MyString { get { return m_myString; } set { m_myString = value; } } public int

问题 how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx. The call should cause a postback because i need the usercontrol to display the changes. i am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event. i had to pass a value to the vb function from the javascript, but i am taking care of it using a
