Hi, I have a project where I synchronize multiple controls. The RadGridView control is bound to an observable collection of data. Whenever I need to select multiple items, I execute

The grid does what it's suppose to do, however, I need to customize all selected rows to have blue font color. At first I tried using

However I quickly learned that this will only work for rows currently visible (based on some other threads I have read). The item itself does not have any kind of "IsSelected" property, so customizing styles probably will not work. I am looking for a c#-based code solution to find all necessary rows and change the Foreground property.

Thanks in advance

Hi,
I followed this example to add a button column in my grid using the data template solution
http://www.telerik.com/help/wpf/gridview-add-button-column.html

By default all the buttons have Visibility = "Hidden". I want to button to be made visible when user select a row.
By handling SelectionChanged Event and accessing SelectedItem I do get the selected row. But after that I have no idea how to access the custom column ..i.e. Radbutton in the selected row and change its property. Any ideas?

Thanks.

Hi Guys,

I downloaded telerik WPF controls trial version and intended to replace the Microsoft TreeView control in our existing product with Telerik RadTreeView. Currently, I am at the stage of building a prototype to make sure that all of the existing features are still working.

We have extended RadTreeView and RadTreeViewItem to support various stuff such as ViewModel binding, custom Events and custom Drag and Drop. 

Our custom drag and drop functionality utilizes the mouse events (i.e. take the mouse position on mouse down, decide whether it triggers a drag operation, end drag on mouse up, etc). 

For the last couple of days, I've been struggling with the conflicts in handling the MouseButtonDown in our drag and drop subsystem and the MouseButtonDown handle in RadTreeViewItem. Based on the Telerik forum posts, I found that the  MouseLeftButtonDown event is handled internally and if we want to handle the events we have to call AddHandler with the third parameter  set to true.

I've done the above workaround and able to handle the MouseLeftButtonDown. However because e.Handled is now set to true, all of the controls up in the visual tree that use MouseLeftButtonDown event must handle the MouseLeftButtonDown event through AddHandler call as well. Unfortunately, it is not possible at the moment to change other subsystem to use the AddHandler.

At the moment, I'm thinking of setting the 'Handled' value to false in the MouseLeftButtonDown handle (from the AddHandler call) and allow the event to be bubbled up. Are there any way to detect that the MouseLeftButtonDown event is handled within the Telerik control? Because our treeviewitem contains a contentcontrol that displays edit button and delete button, if those button are pressed, we still want the Handled property to be true. If there is a guaranteed way to detect whether the MouseLeftButtonDown is handled internally in Telerik control, I could live with it and set the Handled to false when that happen.

Or, is there a way to configure the Telerik RadTreeViewItem to not set the Handled property to true? 

PS: I only have one or two weeks trial left. Does anyone know what happen if the trial expires? Can I still continue building the prototype? 

Kind regards,
Andie

I'm not sure if this is a bug, or if I'm doing something wrong, but when I change a string property of my business object, the gridpropertyview string editor field doesn't reflect the new value, I have to force the control to update (ie. type in the search field) for the new value to be displayed.  The radcombobox seems to update automatically, as does the checkbox.  Is there a way to force the update with the textbox automatically?

Hello,

Is it possible to make the RTF editor in control also an html editor? So if I allow user to create a document inside RTF editor, they can have choice to choose "edit source html" instead?

I thought this control allowed this?

I'm working with a gridview where when I update one cell, it updates other cells both in the same row and other rows. The issue I have is that the cells in other rows correctly update and show the new contents, but any cell on the 'active row' i.e. containing the cell that was edited and presuming that the caret moved to the next cell in the row does not update i.e. if I have cells A,B,C and D on one row and I edit C then when I finished editing C, cell A is updated but it's changes do not show and the control moves to editing cell D. As soon as I move off that row then the cell's correctly shown their new contents. How can I get all of the updated cells to refresh?

Thanks

Hi,

I was wondering if it was possible to stop CTRL+A from selecting every record in the grid when the grid is grouped. When the grid is grouped I would like CTRL+A to select only records from the active group.

I would be grateful if anyone know of a way this could be achieved.

I'm currently using one of the provided themes to color my timeline.
Is it possible to override the color theme such that individual items can be colored based on some condition or property?

For example, I have a timeline containing a List of objects. The objects have a Color property. I would like the object being displayed in the timeline to have a backcolor that matches it's Color property.

Hi,

i am very interested for two DateTimeGroupDescription Extensions.
I need the Steps "Hourly" and "Weekly". Also i need the possibility to customize the date text on the screen (StringFormat). 
Do i have to implement a complete new class derived from PropertyGroupDescriptionBase for these extensions, or is there a better way?

Also it would be great, if i could use DateTimeOffsets for the Dates (specially for DaylightSaving)

Best Regards,
Thomas
