I need to change Height property at Border "borderTooltip" according to value of property Resolution in ManWindow.xaml.cs.

I tried in constructor MainWindow() this:

borderTooltip.Height = 50;

But i can´t access borderTooltip in code.Does somebody know please how to change borderTooltip.Height according to value of Resolution property?

[Solved] Drag and drop inside the RadGridView

I'm only looking for suggestions here, or any similar example should someone have one.

I have a RadGridView with a row template. It has 14 columns. The data template puts an image in one of the 14 columns. The user needs to be able to click and drag this image to another column. I'm assuming that I need to add drag events to the image in the datatemplate. What would be needed for the grid?

Again, this is a vague question, so I'm just looking for suggestions, or ideas on where to head with it.

Filtering in Grid View Exception

Hello,

I am encountering the following Exception after clicking on different column filters repeatedly.

"Object reference not set to an instance of an object."

at Telerik.Windows.Controls.GridView.FilteringDropDown.OnDropDownPopupOpened(Object sender, EventArgs e)
   at Telerik.Windows.Controls.PopupWrapper.OnPopupOpened(Object sender, EventArgs e)
   at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)

There is no particular sequence to get the Exception, But clicking on different column filters randomly one after the other gives this Exception. I am using Version 2010.1.309.35

Any ideeas why this occurs?

Thanks

Windows Explorer type view

Can you, with tile viewer (or maybe a mixture of tile view and others) create a windows explorer type view (on the explorer menu, choose Views, then List, Tiles, or Details). Well, I guess you can, but can it be done easily, or is it already done? Only the container part (the list of items), not the tree view and not everything else around it.

I want to databind the control (in my case, with database items.. but more generically anything). I thought about using Template Selectors with the tile view, list view and data grid but thought I had better ask first if there is an existing control for that. (seems like someone in the world would have created something like this already).

Thanks,
Brian

Custom localization doesn't work

Following the rules and procedures stated on your documentation, I've localized a RadGridView using ResourceManager, in this way:
created the local resource files (see attached Capture01.png for resx file for italian language)
created a setting "ChosenCulture" in Settings for defining the startup default culture, set to "it-IT"
on the Window_Loaded event, set the localization with the following code:

LocalizationManager.DefaultResourceManager = ContiACasa.My.Resources.LocalResources.ResourceManager

LocalizationManager.DefaultCulture = Nothing

Thread.CurrentThread.CurrentUICulture = New CultureInfo(My.Settings.ChosenCulture)

Thread.CurrentThread.CurrentCulture = New CultureInfo(My.Settings.ChosenCulture)

The GridView is localized, but the following elements (at least the ones I've found till now) don't change their text, as you can see in the atteched picture:
GridViewGroupPanelText, GridViewGroupPanelTopTextGrouped, GridViewFilterMatchCase

TIA
Ubaldo
