To reproduce: Create a project with RadGridView, add some rows, make sure you have space to perform panning. Exception should occur. Workaround: this.myGridView.ViewDefinition = new MyTableViewDefinition(); public class MyTableViewDefinition : TableViewDefinition { public override IRowView CreateViewUIElement(GridViewInfo viewInfo) { return new MyGridTableElement(); } } public class MyGridTableElement : GridTableElement { protected override void OnPanGesture(Telerik.WinControls.PanGestureEventArgs args) { if (args.IsBegin && (this.RowScroller.Scrollbar.ControlBoundingRectangle.Contains(args.Location) || this.ColumnScroller.Scrollbar.ControlBoundingRectangle.Contains(args.Location) || this.ViewElement.TopPinnedRows.ControlBoundingRectangle.Contains(args.Location))) { return; } bool containsCurrent = (this.GridViewElement.CurrentRow == null && this.GridViewElement.Template == this.ViewTemplate); if (!containsCurrent) { foreach (IRowView child in this.GridViewElement.GetRowViews(this.GridViewElement.CurrentRow.ViewInfo)) { containsCurrent |= (child == this); } } if (!containsCurrent) { return; } this.GridViewElement.EndEdit(); int newVerticalValue = this.RowScroller.Scrollbar.Value - args.Offset.Height; if (newVerticalValue > this.RowScroller.Scrollbar.Maximum - this.RowScroller.Scrollbar.LargeChange + 1) { newVerticalValue = this.RowScroller.Scrollbar.Maximum - this.RowScroller.Scrollbar.LargeChange + 1; } if (newVerticalValue < this.RowScroller.Scrollbar.Minimum) { newVerticalValue = this.RowScroller.Scrollbar.Minimum; } this.RowScroller.Scrollbar.Value = newVerticalValue; int newHorizontalValue = this.ColumnScroller.Scrollbar.Value - args.Offset.Width; if (newHorizontalValue > this.ColumnScroller.Scrollbar.Maximum - this.ColumnScroller.Scrollbar.LargeChange + 1) { newHorizontalValue = this.ColumnScroller.Scrollbar.Maximum - this.ColumnScroller.Scrollbar.LargeChange + 1; } if (newHorizontalValue < this.ColumnScroller.Scrollbar.Minimum) { newHorizontalValue = this.ColumnScroller.Scrollbar.Minimum; } RadScrollBarElement scrollbar = this.ColumnScroller.Scrollbar; if (newHorizontalValue > scrollbar.Maximum) { newHorizontalValue = scrollbar.Maximum; } else if (newHorizontalValue < 0) { newHorizontalValue = 0; } this.ColumnScroller.Scrollbar.Value = newHorizontalValue; args.Handled = true; } }
