Gridsplitter Query in WPF

Question

0.00/5 (No votes)

See more:

I have a Grid with 4 rows.

2nd row has a grid splitter

4th row has a status bar. I want to make sure that, no matter how the user moves the grid splitter - The status bar

Should remain fixed at bottom of the window.

What is happening right now is that, when user moves the gridsplitter too much downwards, the status bar is pushed out of the window.

what can I do to avoid this ?

This is my code.

XML

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" MinHeight="100"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="*" MinHeight="100"></RowDefinition>
            <RowDefinition Height="Auto"></RowDefinition>
        </Grid.RowDefinitions>

        <GridSplitter Grid.Row="1" Height="10" HorizontalAlignment="Stretch" VerticalAlignment="Center"></GridSplitter>

        <StatusBar Grid.Row="3">
            <TextBox Text="Welcome"></TextBox>
        </StatusBar>

    </Grid>
</Window>

Solution 1

Use two Grid's one with an inner Grid and the StatusBar and the inner grid contains the three rows

XML

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" MinHeight="100"/>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*" MinHeight="100"/>
        </Grid.RowDefinitions>
 
        <GridSplitter Grid.Row="2" Height="10" HorizontalAlignment="Stretch" VerticalAlignment="Top"/>
    </Grid>

 
    <StatusBar Grid.Row="1">
        <TextBox Text="Welcome"/>
    </StatusBar>
 
</Grid>

Thanks Simon, That solves my main problem.

Another thing i am still facing is, the user can drag the gridsplitter outside the viewable window ( There is no way to pull it back ). Is there any way I can restrict to be inside the widnow.

put your GridSplitter at the top of the third row, that should fix the problem

Thanks Simon, But I didn't get you

We have Set Grid.Row = 1 for grid splitter.
So it is in 2nd row.
ie. Above the 3rd row

When you set Grid.Row="1" then it's in the second row in the grid it is located assuming it has atleast 2 rows.
I've updated the answer to reflect what I'm suggesting
