Fill dockpanel with child control

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :WPF

Hi, I have a win forms program which I am trying to write in WPF. I have a DockPanel which is 800x600, and inside that I want to add 1 child control at a time to fill the available space. In winforms this worked by just setting the item to Dock fill. I have set the dockPanel to LastChildFill, the problem is the child control I am trying to add is 400x300. In Winforms this was automatically increased to 800x600, and this is what I am trying to achieve with the dockPanel, but I am not sure how.

If I remove the height and width that are set in the control, then this does fill as expected. So is there anyway to get the dockpanel to override the child controls size, and make sure it fills the available area?

Removing a (child) user control from an observable collection

Hey all, so I have an ObservableCollection of UserControls.  These user controls have their own xaml and each of these has some type of "Close" button so it would be removed from the ObservableCollection. A groupbox is binded to the ObservableCollection so it would show all the UserControls.  When a user clicks on the "Close" button, the user control is removed from the ObservableCollection and thus, the groupbox.  How can I do this?  I've tried something like   (this .Parent as ObservableCollection<asdf>).Remove(this );   where asdf is a UserControl but I get a bunch of compiler errors.

How can I register a name for a control that is an ItemsControl child?

Hello, How can I register a name for a control that is an ItemsControl child? When I create the controls dynamically in code, the RegisterName works just fine.  However, when those same controls are created by the ItemsControl XAML, RegisterName does not work. Here is the XAML which correctly generates what I want: <Canvas Name="Tab_CanvasTabs"> <Canvas.Resources> <local:CategoryTabs x:Key="myTabs" /> </Canvas.Resources> <ItemsControl Name="Tab_ItemsControl" ItemsSource="{Binding Source={StaticResource myTabs}}"> <ItemsControl.Template> <ControlTemplate TargetType="ItemsControl"> <ItemsPresenter /> </ControlTemplate> </ItemsControl.Template> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <DataTemplate.Resources> </DataTemplate.Resources> <Canvas Name="Tab_Canvas_X" Tag="{Binding Path=Number}" MouseLeftButtonDown="Event_CategoryTab_Canvas_MouseLeftButtonDown" MouseLeftButtonUp="Event

Sharing value from child control to parent control.


I am relatively new to this, but here is my problem.

I have a parent and a child control. Within the child control I have a dropdown list. Based on dropdown list's selected value I would like to toggle Visibility of Panel in parent control. For instance if I select Show in child control dropdown list, I need to pass true to parent control to make Panel visible and vice versa. How should I do that. I have read that can be done via the event handling and have seen certain scenarios but I am not clear on that. Please help!

Not able to access child controls in user control using javascript



I have a user control "SettingsControl" containing an ajax:CollapsiblePanelExtender which in turn has a GridView (gridView) and checkBoxes. On top of GridView we have two LinkButtons "Select All" and "Clear All". I have written to enable select all and clear all functionality. Select All should select all the rows in the grid by calling the following JavaScript written on the Client .aspx file.

function SelectAll(chk)
    //get reference of GridView control
    var grid = document.getElementById('<%= SettingsControl1.FindControl("gridView").ClientID %>');
    //variable to contain the cell of the grid
    var cell;

    if (grid.rows.length > 0)
        //loop starts from 1. rows[0] points to the header.
        for (i=1; i<grid.rows.length; i++)
            //get the reference of first column
            cell = grid.rows[i].cells[0];
