Resize WPF mapcontrol

[sapnas]

Is there a sample code to Resize WPF map control? Any help is greatly appreciated.

Hi,

Can you provide some more information about what you would like to achieve? Do you mean allowing the user to resize the map control at runtime, or just having the map control automatically fill the remaining space within your application?

Cheers

Mapcontrol automatically fill the remaining space within the grid when resized. although I resize the grid the map in the map control does not change. I have to manually zoom in to fill the grid.

Hi,

If I understand correctly then, you have a grid probably with multiple rows and the map control provides the content for one of these rows. If this is the case then you should just be able to use an asterisk in the grid row size definition to indicate that that row should fill all the remaining available space e.g.

<Grid.RowDefinitions>
    <RowDefinition Height="100" />
    <RowDefinition Height="200" />
    <RowDefinition Height="*"/>
</Grid.RowDefinitions>

...

<esri:Map Grid.Row=2 .../>

It fills in during the initial load. But when the user maximizes the application after load the map does not fill in. I'm not sure on how to set the extent.

<Grid Name="grid1"  >
                            <esri:Map x:Name="_map" UseAcceleratedDisplay="False"   Margin="14,7,13,18" >
                              
                            </esri:Map>
</Grid>


private void Window_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            if ( this.IsLoaded)
            {

                grid1.Height = e.NewSize.Height - 136;
                grid1.Width = e.NewSize.Width - 261;
            }
          
          
        }

Hi,

You should take a look at the MaintainExtentBehavior in the ESRI.ArcGIS.Client.Behaviors namespace.

There's a sample in the Sample Application installed with the SDK under Mapping > Behaviors & Actions.
