WPF Multiline Textbox

To make a textbox multiline unlike windows forms .Multiline = “True”, in WPF you have to set these 3 properties of TextBox Control.

1. TextWrapping="Wrap"
2. VerticalScrollBarVisibility="Visible"
3. AcceptsReturn="True"

e.g.

<TextBox Height="66" Margin="563,46,265,0" Name="textBox1" VerticalAlignment="Top" AcceptsReturn="True" TextWrapping="Wrap" VerticalScrollBarVisibility="Visible"/>

Get Checkbox state in WPF

In normal WinForms application you use Checkbox.Checked property to get or set value from your checkbox control, but when you try same thing in a WPF application you will get an error when you do the following.

   1: this.chkIsDayOff.Checked = _selectedOccasionType.BlnIsDayOff;

and the error will be …

“The event 'System.Windows.Controls.Primitives.ToggleButton.Checked' can only appear on the left hand side of += or –=”

Because Checked which was property in WinForms, is now Event in WPF.


To resolve this issue use IsChecked Property, both for setting to checkbox or getting from checkbox.

   1: this.chkIsDayOff.IsChecked = _SelectedOccasionType.BlnIsDayOff;
