Hello thereWhen I click on checkbox, I want the textbox to appear and enter the value.
Or when I remove the checkbox, I want the department checkboxes to come as a list at the bottom. But the textbox always comes with the checkbox.

For example:

AllDepartment is checked --->Textbox show.

AllDepartment is not checked ----> Show Open other checkbox list(Healthy checkbox,Banking checkbox, ...vs) and textbox show.

What I have tried:

xmal

<GroupBox x:Name="groupBox" Header="Page" HorizontalAlignment="Left" Height="300" VerticalAlignment="Top" Width="782" Margin="-9,0,0,0">

        <StackPanel Orientation="Vertical" VerticalAlignment="Top">
            <StackPanel Orientation="Horizontal">
                <CheckBox x:Name="Department" Content="All Department" IsChecked="{Binding AllDepartmentCheck}"></CheckBox>
                <TextBox  Text="{Binding AllDeparmentCount}" Visibility="{Binding allDepartmentVisibility}"/>
            </StackPanel>
            <Button x:Name="button" Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75"/>
        </StackPanel>
    </GroupBox>

public bool AllDepartmentCheck
{
    get { return allDepartmentCheck; }
    set
    { 
        allDepartmentCheck = value; 
        allDepartmentCheck = ( allDepartmentCheck != null );
        OnPropertyChanged("allDepartmentCheck");
    }
}

public void Add()

//this adding function code.
