user-controls

问题 So I'm attempting to get the userinputs when someone presses hotkeys, also outside the form (in this case SHIFT+A). Now since I wanted to add tabs to my forms application I decided to go with usercontrols, now the problem is, that I am unable to access the formclosing event (from form1) on the usercontrol, meaning I would have to somehow parse whatever I wanted to execute in the formclosing event. Usercontrol (named home) public partial class Home : UserControl { [System.Runtime

问题 This is not a duplicate! When I failed I tried to look to similar posts but without success. I cannot understand why OnUCItemsSourceChanged is not called? I'm pretty sure that I miss something simple but I cannot find it. I have Window that contains UserControl1 which has attached collection property that is bound to Window 's WindowCollection collection. I expect UserControl1.OnUCItemsSourceChanged to be called when I add items to WindowCollection . But it doesn't happen. What I miss?

问题 I have a listview which I would like to fill with self created user controls.But the problem is that the properties in the user control is not set. The usercontrols are displayed but the property values I enter is not set. Why is that? Here is the aspx code. <div id="productView" class="productsMain"> <div id="groupHeader" class="productsGroupHeader"> <asp:Label ID="lblGroupHeader" runat="server" Text="Gruppe" /> </div> <asp:ListView ID="pListView" runat="server"> <LayoutTemplate> <ul class=

问题 I am making a user control in MS Visual C#, and there is one thing that I just can't find an answer to: How do I limit which dimensions a control can be resized in during design view? For a clear example of what I'm asking, the built in TrackBar control can only only be made wider, not taller, and only displays the resizing squares on the left and right in design mode. Is there a way to replicate this for a user control? I have tried setting MinimumSize and MaximumSize values in the designer
