Hi everyone
I just found how to do that for copied cells, How to do it for pasted cells?
Thaks for help, but I made my custom copy and paste functionality.
Hello,
I attached a new sample to help you get started with modifying the pasted cells. I added a method that styles each cell from the SelectedCells collection from the SelectionSettings object of the XamGrid and removed any styling that was occurring in the copy event.
Please review my sample and let me know if you have any questions. WpfApplication1 (modifyPastedCells).zip

Hello Vasily,
The sample demonstrated how to style the pasted cells. Unfortunately the ClipboardPasting event doesn't expose a selected cells collection as an event argument to properly achieve your requirement with ease. Therefore you are going to have to manually keep track of the pasted cells by first inspecting the ActiveCell in the ClipboardPasting event and iterating through the rows to find the rest of the pasted cells.

I will spend some more time researching this and I'll follow up tomorrow. Thank you for your patience.
Thanks for the project, but....
DId you run this application? This app is confused me, why cell styles changes for the previously selected cells?
I would expect to paste copied data to another place of the grid. What should I do if I will paste data from the Excel?
The following code will provide you with the ability to modify pasted cells. The two styles are listed in XAML. Please see my attached sample for more details. 0410.WpfApplication1.zip
public partial class MainWindow : Window { private List<CellBase> previouslySelectedCells = null; List<CellBase> selectedCells = null; bool IsValidSelectedRec; ComponentData data = new ComponentData(); public MainWindow() { InitializeComponent(); this.DataContext = data.GenerateData(50); } private void xGrid_ClipboardPasting(object sender, Infragistics.Controls.Grids.ClipboardPastingEventArgs e) { if (IsValidSelectedRec) { // Color in blue the valid cell selection System.Windows.Style CellStyleResource = this.Resources["CopiedCellStyle"] as System.Windows.Style; this.SetCellStyle(selectedCells, CellStyleResource); } else { // Color in red the invalid cell selection System.Windows.Style CellStyleResource = this.Resources["InvalidSelectionCellStyle"] as System.Windows.Style; this.SetCellStyle(selectedCells, CellStyleResource); } } private void xGrid_ClipboardCopying(object sender, Infragistics.Controls.Grids.ClipboardCopyingEventArgs e) { // Get selected cells List<CellBase> selectedCells = new List<CellBase>(e.SelectedItems); previouslySelectedCells = selectedCells; // Clear the style of the previously selected cells if (previouslySelectedCells != null && previouslySelectedCells.Count > 0) { this.SetCellStyle(previouslySelectedCells, null); } // Check if the selected region of cells is valid for pasting IsValidSelectedRec = e.ValidateSelectedRectangle(); } private void SetCellStyle(List<CellBase> cells, System.Windows.Style cellsStyle) { foreach (CellBase cell in previouslySelectedCells) { if (cell is Cell) { cell.Style = cellsStyle; } // Set a new style to the copied cells } } }
Let me know if you have any questions.
