how to copy cell data

Hello, Fabrizio,

RadGridView supports built-in Copy/Paste functionality, which allows you to store text in the Clipboard and then paste it in a different location. The copying functionality in RadGridView is controlled via the ClipboardCopyMode property. More information on this topic you can find here: https://docs.telerik.com/devtools/winforms/controls/gridview/copy-paste-cut

I hope this information is useful. Should you have other questions do not hesitate to ask.

Hi, Fabrizio,

Thank you for providing additional information.

RadGridView is not supposed to perform copy/paste operation inside the new row. However, you can easily achieve when modifying the default paste behavior by creating a custom grid. Please refer to the following example:

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();

        for (int i = 1; i <=5; i++)
        {
          this.radGridView1.Columns.Add("Misura "+i);
        }
        this.radGridView1.SelectionMode = GridViewSelectionMode.FullRowSelect;

    }
}

public class CustomGrid : RadGridView
{
    protected override RadGridViewElement CreateGridViewElement()
    {
        return new CustomRadGridViewElement();
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadGridView).FullName;
        }
    }
}

public class CustomRadGridViewElement : RadGridViewElement
{
    protected override MasterGridViewTemplate CreateTemplate()
    {
        return new CustomMasterGridViewTemplate();
    }

    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadGridViewElement);
        }
    }
}
public class CustomMasterGridViewTemplate : MasterGridViewTemplate
{
    public override void Paste()
    {
        if (Clipboard.ContainsData(DataFormats.Text))
        {
            string data = Clipboard.GetData(DataFormats.Text).ToString();

            if (data != string.Empty && this.Owner.CurrentRow is GridViewNewRowInfo)
            {
                int columnIndex = this.Owner.CurrentColumn.Index;
                string[] rowsInfo = data.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
                foreach (string rowInfo in rowsInfo)
                {
                    string[] cellsInfo = rowInfo.Split(new string[] { "\t" }, StringSplitOptions.RemoveEmptyEntries);

                    GridViewRowInfo rowToInsert = this.Owner.Rows.NewRow();
                    for (int i = 0; i < cellsInfo.Length; i++)
                    {
                        rowToInsert.Cells[i + columnIndex].Value = cellsInfo[i];
                    }
                    this.Owner.Rows.Add(rowToInsert);
                }
            }
        }
    }
}

I hope this helps. Should you have other questions do not hesitate to ask.

Hi Nadya
First of all thank you very much for your patience, I regret it but I can't make it work. I have tried with your code but for sure it is I who am not able to make it work. After I added the classes with the routines in overrides I don't know how to call the Paste () routine from the RadGridView on the Form. I am attaching my code.

Thank you very much and sorry again

Hi, Fabrizio,

According to the provided code snippet, it is not clear how you initialize the grid and whether you use the default RadGridView or the custom one. Could you please make sure that you use the custom grid in your project in order to allow the logic in the overridden Paste method to be executed.

Me.RadGridView1 = New CustomGrid()

I attached a project in VB for your reference. When using Ctrl+ C/Ctrl+V key combinations you will be able to select a row and paste it into the new row as demonstrated in the gif file from my previous post. Note, that this is a sample example and may not cover all possible cases. Feel free to modify or extend it in order to best fit your scenario.

I hope this information helps.
