Answer 1

Perhaps you can change the first stackpanel.Visibility to Collapsed as example below:

Markup:
<Window x:Class="GridPanelTest.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <StackPanel>
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <StackPanel Name="firstPanel">
                <TextBlock Text="First cell"/>
            </StackPanel>
            <StackPanel Grid.Row="1">
                <TextBlock Text="Second cell"/>
            </StackPanel>
        </Grid>
        <Button Content="Test" Click="Button_Click"/>
    </StackPanel>
</Window>


Code:
using System.Windows;

namespace GridPanelTest
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            firstPanel.Visibility = Visibility.Collapsed;
        }
    }
}

Hi Rammohan,

Could you post a simple repro (markup/code) because it helps me to understand the problem better by reading the code and trying it?

Thanks,

Answer 7

The repro you shared out is pretty big. There’re many stackpanels, and I don’t know which one you want to collapse.  Is it possible for you to simplify the repro?  And Could you be specific on which stackpanel (like including the panel name) you want it be collapsed?  Thanks.

Answer 8

Hi william,


I repro my application . i fixed it. throught

 

public void Refrencestackremove()

{

ww.StackPanelTopBodyPanleCaptions.Height = 0;

 

GridLength gl = new GridLength(0.0);

ww.TopBodyPanel.RowDefinitions[0].Height = gl;

}

#endregion

 

actually i used the grids under the stack panels that is why i used above function. it's working fine now.


Thanks
Ram
