Grid - Column width and ScrollViewer

    Question

  • Hi

    I am having a problem with the width, high and the ScrollViewer

    I am defining

    <Grid>
    	<Grid.ColumnDefinitions>
    		<ColumnDefinition Width="*" />
    	</Grid.ColumnDefinitions>
    	<Grid.RowDefinitions>
    		<RowDefinition Height="*" />
    	</Grid.RowDefinitions>
    	
    	<ScrollViewer ScrollViewer.HorizontalScrollBarVisibility="Auto" 
    			Grid.Column="0" Grid.Row="0"
    			ScrollViewer.VerticalScrollBarVisibility="Auto" >
    		<toolkit:DataGrid 
    			Grid.Column="0" Grid.Row="0">
    			.
    			.
    		</toolkit:DataGrid>
    	</ScrollViewer>
    	
    </Grid>

    when the DataGrid load the data, the rows and columns exceed the grid dimensions, the vertical scroll work perfect

    but the horizontal scroll never appear, because the grid extend the column and not limit the width to the container

    I need the scroll vertical and horizontal, but only the vertical is effective, the horizontal expands because the grid never limits the width of datagrid

    Note: the Grid is inside stackpanel

    greetings

  • Hi Leandro,

    In order to resolve this problem, the Grid must know the width you desired it to be.

    You can either give it a fix width, bind its width to some parent to calculate it dynamically, or maybe change the layout design of its parent (replace the stackpanel?).

    Feel free to share the layout, including the stackpanel, if you still have any problems.

    Best regards,

  • It's kind of weird why datagrid has the same value for grid.column and grid.row as your scrollviewer in your xaml code.  To me you are implementing 2 controls at the same column and row (overlapping?) ... :s

  • Hi,

    Normally the data grid itself has a ScrollViewer as the top panel such as WPF DataGrid.

    Why would you want another one on top of it?

    Meanwhile, could you show the StackPanel definition?

    Regards

  • hi

    When the columns not exede the width the vertical scroll work perfect

    but the columns are dynamic, and when it exede the application width, the Grid not limite, the height is limited but the width not

    in the button of the image (mark with red) you can see the horizontal scroll, but the DataGrid is not limited

    I try to use

    MaxHeight="{Binding ActualHeight, ElementName=ParentElementName}"

    in the ScrollView, but I don´t know what control can apply the correct the height correctly

    greetings

  • Hi Leandro Tuttini,

    If you don't want to provide the grid with unlimited space, my suggestion is to replace the stackpanel with a Grid or Dockpanel.

    If you have any trouble applying it, please post your code so we can provide more detail suggestiosn.

    Best regards,

  • Hi

    But I have a Grid (inside is the scrollview and datagrid), and it limit perfect the vertical datagrid to show me the vertical scroll

    but not apply the same concept in the horizontal direction, the datagrid expend without limit

    if the grid in the same way would limit the horizontal direction would not have this problem

    saludos

  • why not get rid of the scroll viewer and just use the scrolling built into the datagrid?

  • Hi Andrew

    I try define the scroll properties inside datagrid, but the effect is the same

    only the vertical scroll is enable, in the horizontal expand the column without limit

  • is the grid in a horizontal stack panel? if so it will not scroll as the grid thinks that it fits its parent container fine, while the stack panel extends beyond the bounds of its parent.  Put it in a dockpanel or just grid instead and that will stop that behaviour if i've picked up what the issue is right.

  • The StackPanel will tell the Grid that there are unlimited space available in horizontal direction. So it would not work.

    My suggestion remains the same: replace the stackpanel in the visualtree. You can use a DockPanel, or some combination of panels to accomplish it. You can post more detials about your layout panels if you encounter any problems.
