Answer 1

you can pass the value from main page to user control by creating property in main page and bind that property to the property of user control.

Please mark as Answer, if it helps you .

Answer 2

Hi. If there is not any relation with both then You may use event handlers or action for this purpose by creating your eventsArgs class.

Answer 3

UserControl cmp = new UserControl ();
            cmp.DealIdRow = dealId;

Hi UserControl class is the base class all usercontrol. So there is no DealIRow in the UserControl.

As your mentioned that your question is How to Pass The vale From usercontrol to another control.

I suggest you to change the DealId Property to DependencyProperty.

Such as

        
public int DealId
        {
            get { return (int)GetValue(DealIdProperty); }
            set { SetValue(DealIdProperty, value); }
        }

        // Using a DependencyProperty as the backing store for DealId.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty DealIdProperty =
            DependencyProperty.Register("DealId", typeof(int), typeof(CompanyUCtrl), new PropertyMetadata(0));

Then you can bind any properties to DealId as you wish.Hope helpful.
