Re: GridSplitter won't Stick!?!

The outer StackPanel is the problem. Get rid of that and your layout will work.

May want to also loose the MaxHeight="600" on the TabControl.

Thanks, that did the job! The grid was contained in another grid so I had to add Grid.Column="1" to get to show up in the right place.

If CodeProject is the only site you can access you're not going to be able to download Silverlight.

Hi,
I am developing WPF custom controls. I want to know the name of the evnt which gets fired when the user deletes the custom control from the cider. I found "public event RoutedEventHandler Unloaded" event of some help, but it gets fired when both control is deleted from cider & the xaml page is unloaded. I am seraching for an event (event name)which gets fired only when a control is deleted from cider.

Thanks,
Vinod

You can check if the control is in design mode and then run your code.

DesignerProperties.GetIsInDesignMode(new DependencyObject())

Search the web for" is in design mode" Very easy to use.

Hi Karl,
I want to know which event gets fired when the control is deleted from window in Cider.
How does IsInDesignMode will be helpful in that ?

It's not.

I'll do some checking and see if I can find the information you need.

Vinod,

Trying to figure out "why" you need your control to be notified when being removed from Cider. Is there some clean up you need? If so, IDisposable may work for you.

Let me know.

Hi Karl,
Thanks for ur reply.
I checked by implementing IDispose, but I didn't get notification in dispose();.
I found another way of doing this task, its by providing a PrimarySelectionTaskProviderfor the Window class:

    internal class FSFWindowTaskProvider : PrimarySelectionTaskProvider {

        /// <summary>
        /// Constructor
        /// </summary>
        public FSFWindowTaskProvider() {

        }

        /// <summary>
        /// This function wil be called when a control is selected in WPF window
        /// </summary>
        /// <param name="item">the currently selected control</param>
        protected override void Activate(ModelItem item) {
            ModelService service = Context.Services.GetService(typeof(ModelService)) as ModelService;
            service.ModelChanged += new EventHandler<ModelChangedEventArgs>(service_ModelChanged);
            base.Activate(item);
        }

        private void service_ModelChanged(object sender, ModelChangedEventArgs e) {
            // Get the removed Items from window
            IEnumerable<Microsoft.Windows.Design.Model.ModelItem> enumerator = e.ItemsRemoved;
            foreach (ModelItem mi in enumerator) {
                // Get the name of the control deleted
                MessageBox.Show(mi.Properties["Name"].ComputedValue.ToString() + "deleted");
                string cntrlName = mi.Properties["Name"].ComputedValue.ToString();
                if (string.IsNullOrEmpty(cntrlName)) {
                    continue;
                }
                // Write the clean up code
            }

        }
    }

       internal class Metadata : IRegisterMetadata {
....
 // Primary selection task provider for FSFWindow
                builder.AddCustomAttributes(typeof(myWindow), // mywindow is my custom class
                    new FeatureAttribute(typeof(FSFWindowTaskProvider)));
      }

In service_ModelChanged, we will get the notification for control deletion.

Vinod,

I got this from my team. Please verify you are doing this:

Make sure your customer also overrides Deactivate and removes the event handler he’s added. A new task provider will be created and activated each time his control gets selected.

Here is another block of code I was sent by a team member.

Something slightly tighter is – I don’t know if they’re writing against the old or new Model, hopefully this should work on both.

   private void service_ModelChanged(object sender, ModelChangedEventArgs e) {
       // Get the removed Items from window
       foreach (ModelItem mi in = e.ItemsRemoved) {
           // Get the name of the control deleted
 if (typeof(MyControl).IsAssignableFrom(mi.ItemType)) {
           // Write the clean up code
}
       }

Cheers, Karl

Re: Please help DataTemplate

8-Jul-09 0:23

Hi Karl,
thanks for the reply. but I can not check for a particular type of control. there
are any custom controls. I have one doubt , can I track the Ctrl + X event here. I mean
I want to know whether ther the user has pressed Ctrl-X or Delete button. In

Hello,
I am just a begginer in WPF. My query is written below . please give a solution.
I have two classes named "Student" and "Employee" both derived from a base class named "Person". I want seperate data templates for student and employee. ie. for student i wish to display only name with a text box and for emplyee i want two text boxed with name and salary. I will populate a list by setting the item source as Person objects. now when i click on the list the template corresponding to the class that is "Student" or "Employee" should be displayed in the screen. how can i do this.?
