RadGridView - Copy Performance Issue

[Álvaro]

Hi!

I have a RadGridView (v2022.1.222.40) with a high amount of elements (~90000) and when trying to copy a column I see that the Copying is taking too long. Even if I do a dummy code processing the data.

I cancel all the formats except DataFormats.Text, and it still takes too much time.

I have thought about canceling all the formats and saving the data in a variable instead of the clipboard but if I cancel everything, the Pasting event won't be triggered later... Any suggestion?

Here is my code:

private void gridView_Copying(object sender, GridViewClipboardEventArgs e)
{
    if (e.Format != DataFormats.Text)
    {
        e.Cancel = true;
        return;
    }

    // Do some dummy code

    // Save it in the Clipboard
    e.DataObject.SetData(nameof(MyCustomModel), items);
}

Hi Álvaro,

Thank you for reaching out to us.

You can try also to specify the DataFormat of the SetData() method with Text and UnicodeText to trigger the pasting. You can cancel all the formats and manually create the DataObject method. Here is what you can try:

DataObject dataObject = new DataObject();
dataObject.SetData(DataFormats.UnicodeText, false, data);
dataObject.SetData(DataFormats.Text, false, data);
Clipboard.SetDataObject(dataObject);

Give it a try and let me know how it goes.
