Popup on CurrentCellEditBegin

[Tim Stephansen]

Does anyone know how to get the coordinates of a GridCell in a SfDataGrid? I want to have a popup appear with a styled TextBox when the user starts to edit the cell. I want the popup to appear above the cell (but probably bigger than the cell by itself). I have searched and I can't figure out a way to get the cell's location on the screen.

Thank you for any help you can provide!

Hi Tim, 

 

Your requirement can be achieved by handling below three events. Find the code snippet and sample below, 

 

Sample: http://www.syncfusion.com/downloads/support/forum/124895/ze/WpfTestingSample-1614533496 

 

this.SfdataGrid.CurrentCellBeginEdit += SfdataGrid_CurrentCellBeginEdit; 

this.SfdataGrid.CurrentCellEndEdit += SfdataGrid_CurrentCellEndEdit; 

this.SfdataGrid.Loaded += SfdataGrid_Loaded; 

 

/// <summary> 

/// Open the PopUp and places based on cell's position 

/// </summary> 

/// <param name="sender"></param> 

/// <param name="args"></param> 

private void SfdataGrid_CurrentCellBeginEdit(object sender, CurrentCellBeginEditEventArgs args) 

{ 

    var rowline = this.SfdataGrid.GetVisualContainer().ScrollRows.GetVisibleLineAtLineIndex(args.RowColumnIndex.RowIndex); 

    var colline = this.SfdataGrid.GetVisualContainer().ScrollColumns.GetVisibleLineAtLineIndex(args.RowColumnIndex.ColumnIndex); 

 

 

    popUP.PlacementTarget = this.SfdataGrid.GetVisualContainer(); 

    popUP.Placement = PlacementMode.Relative; 

    popUP.HorizontalOffset = colline.ClippedOrigin; 

    popUP.VerticalOffset = rowline.ClippedOrigin; 

    popUP.IsOpen = true; 

} 

 

/// <summary> 

/// Closes the PopUp. 

/// </summary> 

/// <param name="sender"></param> 

/// <param name="args"></param> 

private void SfdataGrid_CurrentCellEndEdit(object sender, CurrentCellEndEditEventArgs args) 

{ 

    popUP.IsOpen = false; 

} 

 

private void SfdataGrid_Loaded(object sender, RoutedEventArgs e) 

{ 

    this.SfdataGrid.GetVisualContainer().ScrollOwner.ScrollChanged += ScrollOwner_ScrollChanged; 

} 

 

/// <summary> 

/// Update the PopUp position while scrolling. 

/// </summary> 

/// <param name="sender"></param> 

/// <param name="e"></param> 

private void ScrollOwner_ScrollChanged(object sender, ScrollChangedEventArgs e) 

{ 

    var currentcell = SfdataGrid.SelectionController.CurrentCellManager; 

 

    if (!currentcell.HasCurrentCell) 

    { 

        popUP.IsOpen = false; 

        return; 

    } 

 

    var rowline = this.SfdataGrid.GetVisualContainer().ScrollRows.GetVisibleLineAtLineIndex(currentcell.CurrentRowColumnIndex.RowIndex); 

    var colline = this.SfdataGrid.GetVisualContainer().ScrollColumns.GetVisibleLineAtLineIndex(currentcell.CurrentRowColumnIndex.ColumnIndex); 

 

    if (rowline == null || colline == null) 

    { 

        popUP.IsOpen = false; 

        return; 

    } 

 

    popUP.HorizontalOffset = colline.ClippedOrigin; 

    popUP.VerticalOffset = rowline.ClippedOrigin; 

    popUP.IsOpen = true; 

}
