I'm making an application for being used in a touch screen. One of the forms shows a listbox with scrollbar activated that is a little bit tricky to use by touching the screen with fingers.
I have tried to make an style that makes bigger buttons inside the scrollbar but I can't apply it to a listbox.
Is it possible to make a style for make bigger buttons in a scrollbar inside a listbox?
Thanks
If you are using Blend then you need to:
1. Right click your ListView
2. Select "Edit Control Parts --> Edit a copy"
3. Now right click the ScrollViewer in "Objects and Timeline"
4. Select "Edit Control Parts --> Edit a copy" again
5. Now you're editing a template for the ScrollViewer and you can play
with the size of the VerticalScrollBar
If you're not using Blend then you are just creating a Template for the ListView that refers to a new Template for the ScrollViewer.

I've created a listview in WPF. The items in there are changing their backgroundcolor by clicking, in this case i deactivated the listview prop 'Focusable'.
For my usecase (on a touchscreen) i want to hide the scrollbar and just scroll by clicking an up/down button at the bottom. One click should scroll the whole page (UP/DOWN) and show the next (so far hided) items.
I'm seraching for a flexible solution and don't want to calculate pixels or smth like that (also the items haven't a fixed height, also the window)
Thanks in advance
First off, it might benefit you to take a look at How do I ask a good question?. Specifically, in your case it would be easier to understand the sitution if you included some of your XAML. However, I do think I have a solution for you.
ItemsControls like the ListView support "content scrolling", meaning the ability to scroll by content/items instead of by pixel. This question gives a solution to finding which items are currently visible in the ListView by accessing the internal ScrollViewer. ScrollViewer.VerticalOffset will tell you the index first visible item and ScrollViewer.ViewportHeight will tell you how many items are visible. To scroll to the "next page", you should just need to:
ScrollViewer.VerticalOffset += ScrollViewer.ViewportHeight;
I am hiding/showing columns and adjusting their widths dynamically. The SfDataGrid has trouble catching up, and in some border cases, calculates the width wrongly, and hides the horizontal scrollbars even though part of a column expands beyond the visible part of the SfDataGrid or is hidden behind the vertical scrollbar.
You can overcome this behavior by customize the style of Scrollviewer and remove the rowspan and columnspan values respectively as mentioned in this article.
You can get the default ScrollViewer style through visual studio designer by right click on the ScrollViewer and navigate through the open context menu to the EditTemplate option. Afterwards just click on the Edit a Copy option.
I build application with ribbonForm by Syncfusion winform.
I want that in one of the ribbon tab it will be a button that alignment to right (all the other buttons alignment to the left).
I made paint to Demonstrate what I mean in the attached image.
How can I do that?
Thanks alot
The tab area of the RibbonControlAdv is a toolstriptabitem. By default its child is ToolStripEx but we can add other controls like button, by add it in toolstrippanel’s controls. To meet your requirement the button has been added to the right side of the Ribbon Tabs.
button = getButton();
this.toolStripTabItem1.Panel.Controls.Add(button);
this.toolStripTabItem1.Panel.Controls.SetChildIndex(button, this.toolStripTabItem1.Panel.Controls.Count - 1);
button.BringToFront();

I created a custom control that looks a lot like the tab buttons in VS 2012. In my control I could set a propertiy to posistion the text and sidebar vertical or horizontal. After playing around with the control I figured there was probably a better way to go about this. So i fired up the Expression Blend preview and suprising enough (only second or third time using blend) was able to create a style to achieve a simliar style button. However, Now I want to have control over the text and sidebar being vertical or horizontal. I would also like to have control over the mouse over color. Is this possible to do via one style or am i going to have to create a bunch of different styles?
If I understood correctly you can achieve what you want to do with event triggers.
Sorry, I don't have any codes or markups to show you.
I just want help to get my scroll bar scroll to 10 rows down in a ListView when I drag the thumb button.
For a visualization just take an example of navigation home screen in Android home page. I want to implement exactly same idea in the vertical ListView or any ScrollViewer container.
If you have focus on one item within a ListView, scrolling is automatic.
item.Focus();
