RadGridView: An error message appears, while typing in a textbox editor of the composite filter dialog, and enter key is pressed

The error message appears when opening the custom option from the filter icon in RadGridView. 

The error message should not appear as there is a text in the textbox. When the enter key is pressed, the textbox value is still not committed which leads to this error. As a workaround, we can create a custom CompositeDataFilterForm override the ProcessCmdKey where we can handle this case.

public class MyCompositeDataFilterForm : CompositeDataFilterForm
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        if(keyData == Keys.Enter)
            this.Controls[2] as RadButton).Focus();
             (this.Controls[2] as RadButton).PerformClick();
        return base.ProcessCmdKey(ref msg, keyData);

private void RadGridView1_CreateCompositeFilterDialog(object sender, GridViewCreateCompositeFilterDialogEventArgs e)
    var newForm = new MyCompositeDataFilterForm();
    e.Dialog = newForm;
