Deleting rows bound to an Observable Collection

[Todd Lichtas]

I have a GridDataControl in WPF that allows the selected row to be deleted by pressing the "delete" key.  I need to capture some information from the record being deleted, but I cannot find the event that fires when the record is being deleted

Hi Todd,

 

Thank you for using Syncfusion products.

 

You can achieve your requirement by handling CollectionChanged event. This event fires whenever a change is done to the underlying Collection like adding, deleting, moving records. From the argument e.Action you can find whether the event is invoked while adding, deleting, or moving records. The deleted records can also be retrieved from the argument e.OldItems.

 

 

Code Snippet:

 

this.SyncGrid.ModelLoaded += new EventHandler(SyncGrid_ModelLoaded);

 

void SyncGrid_ModelLoaded(object sender, EventArgs e)

 {

    this.SyncGrid.Model.View.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(View_CollectionChanged);

 }

 

void View_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)

 {

    if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Remove)

    {

       var Arraylist = ((System.Collections.ArrayList.ReadOnly(e.OldItems)));

       var Item = ((Products)Arraylist[0]);

    }

 }
