问题 I set the property Multiline=true; . I do not want to allow the Enter Key to make a new line. How can I solve this issue? 回答1: That could be as simple as listening to TextChanged event and then executing the following line inside it: txtYourTextBox.Text = txtYourTextBox.Text.Replace(Environment.NewLine, ""); This solution involves some screen flicker though. A better way is to prevent it entirely by listening to KeyDown event: private void txtYourTextBox_KeyDown(object sender, KeyEventArgs e)

The difference, perhaps, is that I'm trying to do this before the ComboBox is loaded or initialised (I

The 2 event handlers below worked fine for me: procedure TForm18.Edit1KeyDown(Sender: TObject; var Key: Word; Shift: TShiftState); begin HideCaret(Edit1.Handle); end; procedure

问题 I am trying to create a TextBox which is readonly and which has no animation or mouse focus using the following xaml style. However I want to be able to change the background colour but this style will not allow changes to the background colour. I think I am not understanding the basic concepts here because it seems it is not possible to simply set the Background property itself, in the same way the foreground property can be set - why is that and how do I create a TextBox style that is read
