dynamic-usercontrols

问题 I have a property and depending upon it's state (say A and B) I either show a usercontrol of animation or a image. Now, if the property changes, I want to trigger the datatemplate selector again. On searching, I found that in WPF I could have used DataTemplate.Trigger but it's not available in WP. So, my question is Is their a way to trigger datatemplate selector so when property changes from state A to B, then appropriate usercontrol gets selected. If yes, then please give some example how

问题 UserControl: private string lastName; public string LastName { get { return lastName; } set { lastName = value; lastNameTextBox.Text = value; } } Form: using (SqlConnection myDatabaseConnection = new SqlConnection(myConnectionString.ConnectionString)) { myDatabaseConnection.Open(); using (SqlCommand SqlCommand = new SqlCommand("Select LasatName from Employee", myDatabaseConnection)) { int i = 0; SqlDataReader DR1 = SqlCommand.ExecuteReader(); while (DR1.Read()) { i++; UserControl2 usercontrol

问题 I have a user control that I dynamically add to a Panel . I also have a couple of other functionality in the aspx page like search which is inside an update panel that causes the page to post back. From what I have read so far is that dynamic control needs to be bound on each page load. This works fine but the issue is that the user control takes a bit of time (like 3s) and thus all request operations takes longer because the user control is being bound every time. If I load the user control

问题 I have different controls in my usercontrols. And load usercontrols dynamically in my form UserControl2 usercontrol = new UserControl2(); usercontrol.Tag = i; usercontrol.Click += usercontrol_Click; flowLayoutPanel1.Controls.Add(usercontrol); private void usercontrol_Click(object sender, EventArgs e) { // handle event } The click event is not firing when I click a control in usercontrol. It only fires when I click on empty area of usercontrol. 回答1: Recurse through all the controls and wire up
