    Hi gyus
    I am using BrowseEditor in my application. There are 3 different scenarios how the user can do the same task of selecting a file for processing:
    1) browse to file using dialog that pops up from browse editor
    2) enter the path by Ctr+V the path to browse editor
    3) drag and drop the file  to browse editor

    1 and 3 are implemented, no problems with them. But I do have a small problem with 2.
    The default behavior I am regular to is that all text is selected when I do Ctrl+A, or if I click the field and it gains focus the whole text is selected. Otherwise I have to manually erase all text by pressing Backspace many times before I can paste new file path.

    And I did something wrong, or browseeditor does not implement Ctrl + A behavior.
    I succeed to do it by :
    private void radBrowseEditor1_KeyUp(object sender, KeyEventArgs e)
        if (e.Control && e.KeyValue.Equals('A'))
            if (radBrowseEditor1 != null)
                if (radBrowseEditor1.BrowseElement != null)
                    if (radBrowseEditor1.BrowseElement.TextBoxItem != null)

    Is it a correct approach?
    And how can I implement the behavior when gaining a focus leads to selecting all?

    Hi Artem,

    Thank you for contacting us.

    You can use the GotFocus method of the TextBoxItem:
    void TextBoxItem_GotFocus(object sender, EventArgs e)
        this.radBrowseEditor1.BrowseElement.TextBoxItem.HostedControl.BeginInvoke(new Action(() =>
            this.radBrowseEditor1.BrowseElement.TextBoxItem.TextBoxControl.SelectionStart = 0;
            this.radBrowseEditor1.BrowseElement.TextBoxItem.TextBoxControl.SelectionLength =

    We need to use BeginInvoke because otherwise the selection is lost since the MouseDown event is fired after the focus event.

    I hope this helps.

    George, many thanks!
    Now my editor knows to select all text both on Ctrl + A pressed and focus gained event.
    It also supports drag and drop. That is already a usable control :)
    I am happy, thanks!
