I have a Silverlight application, containing a scrollviewer in a grid layout.
When I move the scroller down and close this grid with the close button, the scroller remains at the bottom whenever I reopen the grid.
Is there a way I can reset the scroller to the top position?
Hello supriya khamesra,
Please Try this.
Please Put your grid inside scroll viewer and then write your bellow code after grid selection change.
grdDetail.ScrollToVerticalOffset(0d);
OR
grdDetail.ScrollToTop();

So, if you have seen the Windows 11 Store UI. I want to replicate the border or the sliding bar on the side where every time you click a button the border or sliding bar would go to that button and center it self in the middle.
Create a custom template for the button that has an ItemControl of a single border on the left along with the button content, and when it is selected and animate it.
I have a button and I want it to be always at the same location on my form (top-left corner of visible part of the form).
Here is the example:
So when I scroll vertically or horizontally, the button should always be at the top-left corner and it should be visible.
What should I do to make it fixed?
I guess you are using Form's AutoScroll feature.
What about placing Panel with AutoScroll = true on the form and use its scrolling instead? Then you will be able to place a button on a form but over this scrollable panel. So, the scroll rulers will scroll the view panel contents, but the button will stay pinned to the form.
If you don't want to add another container component, then you can add a handler on Scroll event and adjust the button position in response to form scrolling. The ScrollEventArgs argument has ScrollOrientation, NewValue and OldValue to calculate new X/Y position of the control.
On the form, you place a Panel and set: its Dock property to Fill, and AutoScroll property to True.
You place all the other controls inside this panel, but not the button you want to keep visible.
Right-click on the panel->Send-to-Back.
The Panel will adjust the size to match the form; the scrolling will only happen in the panel, so the button will always stay visible(you can set Anchor:Left,Top on it)
In order to be able to scroll(with the mouse wheel), the focus must be on a control inside the scrollable area(inside the Panel), NOT on the button. To prevent the button from getting focus: set TabStop to false on it; also, when it is clicked, you must also set the focus on an other control, by calling:
this.SelectNextControl(the_button, true, true, true, true);
I have an extjs panel. This panel has dynamic contents added into it every time I press a button. This dynamic content gets added to the end of the panel, which is not visible until I do a manual horizontal scroll.
I want to scroll to the right most side everytime a new content is added and user see that content immediately (without manually having to scroll right)
Is there any way, I can automatically horizontally scroll the panel towards the end of the panel in the right
Thx
I have this narrow panel which is basically a list of thumbnails, and i need to be able to scroll over them using buttons.
We have a panel (anchor layout), with containers in it, and each container contains the image.
there isn't space for a scrollbar, and anyway we don't want one.
I thought it would be as easy as in the listener for my button calling panel.getEL().scroll('b',20)
but this isn't working because the scrollHeight === ClientHeight so scroll does nothing.
Is there a technique I am missing or should this work?
So you're using a button to scroll through the images? What about having the button's listener remove/hide the containers/images at the front of the panel to allow the others to use the space?
I Have a Silverlight page with a header menu, a navigation frame, and a footer. In my header menu I want to put a drop down menu, but when I open the menu, it goes behind the frame.
Is there a way to put it forward? Canvas.ZIndex makes no difference at all.
For me to get this to work, the navigation frame had to be in a grid that was a child of the grid my menu was in.
Like so:
Grid "FullPageGrid"
Grid
Menu Stuff
Grid
Navigation Frame
Not sure why that works, but it does.
You can use this free opensource menu for this purpose:
www.sl4popupmenu.codeplex.com
It brings the content on top by placing in a Popup control.
If you can place the drop down menu later in the XAML, it will appear above.
So you want to have this hierarchy:
Grid
Grid
Your navigation frame
Grid
The menu
