BrowseEditor - select all text/clean all

[Artem]

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)
                    radBrowseEditor1.BrowseElement.TextBoxItem.SelectAll();
}

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

Regards,
Artem

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 =
            this.radBrowseEditor1.BrowseElement.TextBoxItem.TextBoxControl.Text.Length;
    }));
}

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!
