Yes after getting access to the clipboard I need to determine how manys are as far as rows goes, that way I know how many rows to provide for the grid or ultra grid.

For example if the user open an excel sheet to copy and paste 100 rows, I want to be able to find the the number of rows that were copied and the provide the grid a 100 rows, also how to give the grid a 100 rows, if you know what i mean.

Hello KeithDudley,

Please use the following code inside the InitializeLayout event of the UltraGrid:

  e.Layout.Override.AllowMultiCellOperations = AllowMultiCellOperation.All;
            e.Layout.Override.AllowAddNew = AllowAddNew.TemplateOnBottom;
            e.Layout.Override.RowSelectors = Infragistics.Win.DefaultableBoolean.True;

Hello KeithDudley,

I have created small sample for you which provides the desired functionality. I am handling the Error event of the UltraGrid and there if the error is about pasting more rows than the UltraGrid actually has, than I am creating those rows in the DataTable that is bound to the UltraGrid as a DataSource.

Also the sample will work only for mentioned scenario, when you are pasting values copied from a single column in excel to you UltraGrid. If you need to extend this functionality please feel free to do so with the provided code.

Please find the code snippet below and let me know if this is what you are looking for:

    public partial class Form1 : Form
    {
        DataTable dt;
        public Form1()
        {
            InitializeComponent();
            dt = new DataTable();
            dt.Columns.Add("Str1", typeof(string));
            dt.Rows.Add();
          
            ultraGrid1.DataSource = dt.DefaultView;
        }

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            e.Layout.Override.CellClickAction = CellClickAction.CellSelect;
            e.Layout.Override.AllowMultiCellOperations = AllowMultiCellOperation.All;
         }
        private void ultraGrid1_Error(object sender, ErrorEventArgs e)
        {
            if (e.ErrorType == ErrorType.MultiCellOperation && e.MultiCellOperationErrorInfo.Operation == MultiCellOperation.Paste)
            {
                e.Cancel = true;
                dt.Rows.RemoveAt(0);
                string[] rows = ((string)Clipboard.GetDataObject().GetData(typeof(string))).Split(new char[] { '\n' });
                foreach (string row in rows)
                {
                    if (row != String.Empty)
                    {
                        string[] cells = row.Split(new char[] { '\r' });
                        foreach (String cel in cells)
                        {
                            if(cel != String.Empty)
                            dt.Rows.Add(cel);
                        }
                    }
                }
            }
        }
    }

I am getting ready to chat with  you on live chat, its better that way,

but I am only going to provide the user one column only, they normally go to an excel template and copy a list values in column A, so I am providing the functionality in a ultra grid with one column so they dont have to depend on the excel sheet. Then once I copied and paste the values into the grid, then close the grid I want to used those values in the grid to  do something. But its one column.

Hello KeithDudley,

I do understand what is your requirement, the I would like to know how many columns are you going to have in your UltraGrid. It would be important for populating the UltraGrid. This also includes creating dynamically your DataTable for example and then binding it to your UltraGrid, or just updating the underlying DataSource of the UltraGrid , from the clipboard, if you do not know the number of the rows in advance.

If you have any other questions please feel free to ask us.
