TreeListView Expand All/ Collapse All Hierarchy Items

Hello Telerik Team,

I want to expand / collapse all hierarchy levels of a RadTreeListView in C# code.
I have multi level hierarchy items (generally 3-4 levels deep)

When I use

radTreeListView.ExpandAllHierarchyItems();

radTreeListView.CollapseAllHierarchyItems();

This only expands or collapses the first level hierarchy, the inner levels are left unchanged.

Any ideas on how to expand or collapse recursively all the way to the last level?

Thanks in Advance.

Tile automatically resizing when content change

Hi,

I use the TileView to display content that can change dynamically. I would like the tiles to adjust to their new content whenever that happens.

Is this possible?

Regards,

Alex

Edit: I realized that the RowHeight property accepted the Auto value. Although my tiles now adjust their height to their content, for some reason a large blank space appears between my tiles (my column count is 1, thus I have 1 tile per row).

How to set column size for tree list view

hi,
I have a question here. Bascially I have a tree list view, they reside in the same grid. This tree list view has three columns.
In my current code, I set each of them fixed width.
Now I want the first column occupies the largest width of the grid, and the other two have fixed size.

So I tried to set the first column size as "Auto", it's not working.
Then I tried to set the first colmn size as "3*", the other two are "*". Still not working.

Anyone knows the answer? Really appreciate it.

<telerik:RadTreeListView Grid.Column="0">

Need Passes Behind the Numeric Indicator

I need to find a way to make the needle of a radial gauge pass over the numeric indicator, much as the needle of a car passes over the odometer. Currently the needle is covered by the numeric indicator when it passes. I am somewhat new to WPF and this may be something that is easy to do but I have not yet found out how to make this happen. Any help would be greatly appreciated.

Thanks in advance,

James

RadRibbonView bug on resizing containing window

Hi

I have a sample solution, in which I've created a clean RadRibbonWindow that has a RadRibbonView, with a single Backstage item and a single RadRibbonTab. I've set the Backstage to be open on start.
When the window is maximised and the Backstage is open, I can not move my window by grabbing the Title bar with the mouse and dragging it around (it automatically maximises on the current screen). This only seems to be an issue in the latest Telerik control set (Version=2012.1.215.40).
If I revert to the previous versions of the Telerik dlls, ( Version=2011.3.1220.40) it works fine:

<Reference Include=

"Telerik.Windows.Controls, Version=2012.1.215.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

/>

<Reference Include=

"Telerik.Windows.Controls.Navigation, Version=2012.1.215.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

/>

<Reference Include=

"Telerik.Windows.Controls.RibbonView, Version=2012.1.215.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

/>

<!--<Reference Include=

"Telerik.Windows.Controls, Version=2011.3.1220.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

/>

<Reference Include=

"Telerik.Windows.Controls.Navigation, Version=2011.3.1220.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

"Telerik.Windows.Controls.RibbonView, Version=2011.3.1220.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL"

/>-->

I have a clean sample solution to illustrate this issue. Please advise as to how I can upload this to an administrator.

Autoscroll when dragging item in TreeView

Hi,

I have a TreeView in my WPF application. Items are allowed to be dragged within the same TreeView. However, while dragging the item, the TreeView does not automatically scroll vertically when mouse approaches top or bottom borders.

I want a similar behavior like in Windows Explorer. When dragging a folder/file if the mouse approaches the border it performs automatic scroll. Otherwise it would be impossible to operate if you have large number of nodes in the tree.

Thank you,

Ruben.
