GridTemplateColumn will not show ContextMenu

[Andy Swanson]

How do I get the ContextMenu to show in a SfDataGrid using a GridTemplateColumn and the grids EditTrigger is set to OnTap? If I set it to DoubleTap the menu will show. I want the same functionality setting the EditTrigger to OnTap.

Hi Andy, 

Thank you for contacting Syncfusion Support. We have analyzed your query. Seems you are looking to show context menu of the element inside EditTemplate. You can achieve your requirement by overriding GridCurrentCellManager as like below code snippet 

Code Example: 

this.datagrid.SelectionController = new SelectionControllerExt(this.datagrid); 

 

public class CurrentCellManager : GridCurrentCellManager 

    { 

    

        public CurrentCellManager(SfDataGrid grid) : base(grid) 

        {  

        } 

 

        internal  void SetSuspendAndResumepdates(Action suspendupdates, Action resumeupdates) 

        { 

            SuspendUpdates = suspendupdates; 

            ResumeUpdates = resumeupdates; 

        } 

       

        public override void ProcessOnTapped(MouseButtonEventArgs e, RowColumnIndex currentRowColumnIndex) 

        { 

            if (dataGrid.EditTrigger == EditTrigger.OnTap && e.ChangedButton != MouseButton.Right) 

                base.ProcessOnTapped(e, currentRowColumnIndex); 

 

            if (CurrentRowColumnIndex == currentRowColumnIndex) 

            { 

                if (!(this.dataGrid is DetailsViewDataGrid)) 

                    ScrollInView(currentRowColumnIndex); 

            } 

        } 

    } 

 

    public class SelectionControllerExt : GridSelectionController 

    { 

        public SelectionControllerExt(SfDataGrid dataGrid) : base(dataGrid) 

        { 

        } 

 

        protected override GridCurrentCellManager CreateCurrentCellManager() 

        { 

            CurrentCellManager currentcellmanager = new CurrentCellManager(DataGrid); 

            currentcellmanager.SetSuspendAndResumepdates(SuspendUpdates,ResumeUpdates); 

            return currentcellmanager; 

        } 

    } 

Please let me know, if your requirement is different from above scenario. 

Thanks,
