Solution 1

C#

txtEditor.Text = File.ReadAllText(openFileDialog.FileName);

You are opening the file from the openFileDialog instead of the one in the selected item of the ListBox.

[edit]
The code should be something like:

C#

private void lbFiles_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    object item = lbFiles.SelectedItem;
    if (item == null)
    {
        txtEditor.Text = "No Item Selected";
    }
    else
    {
        txtEditor.Text = File.ReadAllText(item.ToString());
    }
}

[/edit]

Show how should i do it?

Richard MacCutchan 30-Nov-16 4:45am

What do you mean how? You just select the name from the ListBox item.

Member 11893772 30-Nov-16 4:52am

Its an openfiledialoge in witch you can select multiple text documnents to display it on textbox on selection. that my question?

Richard MacCutchan 30-Nov-16 4:56am

I have just told you what to do; you use the filename that the user has selected in the ListBox. You do not need the OpenFileDialog any more.

Member 11893772 30-Nov-16 4:59am
