E.g: 5 child nodes under a parent node. When try to reorder the child nodes, move 2nd node right above or right below 4th node, both of the actions, target node might be the 4th node based on users mouse behavior. How can we identity user wants to move the 2nd node above or below 4th node? 

Hi,

I have a problem on the CausesValidation between Main Form and Child Form. 
In the Main Form (midChildContainer form), I have a commandbar control with 2 buttons.  When those buttons are clicked, a function in Child Form will be involved. 

However, I want the validating event in the child form to be triggered when the first button in Main Form is clicked.  When, the other button is clicked, the validating event should not be fired.

I tried to set the causesvalidation in CommandBar to False.  Then, whatever buttons is clicked, the validating event never fire. 
Is there any way to do?  Thanks!

The following is the code:

Main Form Designer:

Child Form Designer:

Is there a RadControl for WinForms that will do this?

When I google on this, I see examples on how to program the default PictureBox control that ships with Visual Studio, but I was wondering if there was an existing RadControl that can already do this, and save myself some development time.

Thanks

Hello, I'm trying to create a grid that allows editing when I click a command column button but only for that row, all other rows should stay read-only to reduce human error.  Any ideas?

Thanks,
Jason

I have a grid view, which values can be edited by the user. I want to refresh the content of the grid, if the user changes the value of the cell. So say I have : 

1, 2, 3 as the initial state. If the user changes the value 2 to 5, i want the values in the grid to show , 1,5,6. ( this is a new list that's get assigned as data source to the gridview )

My understanding is that in order to refresh the grid. One has to create a new reference of the list and reasign it to the data source. 

When this is done in the CellValueChanged event, the gridview crashes, with the following error. 

How does one refresh the grid view after a value has changed ? 

- Thanks 

Steps to get the error : 

1. Create a GridView 
2. Assign it for data source a list of your favorite object. Strings or what not. 
3. Add a handler for the CellValueChanged. 
4. On the CellValueChanged handler, asign a new list of strings of your  to the grid's data source. 
5. Build start. Edit a cell, and hit enter.

Hey at Telerik

I have a problem when binding gridview to a List<Car>.
The Car object contains two objects Engine and CarColor.

If an Engine or CarColor is initialized on the car object the e.Value in the

 

rgvCars_CellEndEdit event is correctly changed and parsed and object is updated.

If no Engine or CarColor object is initialized on the Car object and i try to set for instance and engine in the combobox, the e.Value in  the rgvCars_CellEndEdit event is null and the object is not updated.

How do i set an Engine or CarColor on the Car object if there's no Engine or CarColor initialized ??

I have include an example (Without an assembly) that shows the problem at hand when you try to select for intance an Engine on the Car that doesn't have an Engine object initialzed.

Link to example. http://kort2.lifa.dk/Examples/GridViewCellEndEditIssue.zip

Hi all,
I using wraptext to format a header like:
rgvBob.Columns(6).Width = 60
rgvBob.Columns(6).HeaderText = "Internal Diameter"
rgvBob.Columns(6).WrapText = True

and the grid works fine, but when I use a ViewDefinition in my grid, the propertie wraptext above is ignored and the header doesn´t show the text in 2 lines.
There are some properties in ViewDefinition to do a wraptext in header?

tks,
Nelson

How can I stop the items in the carousel from rotating?

I tried setting AnimationsToApply to None, but then all my items appeared stacked on top of each other. I also tried setting EnableLooping to False, and that seemed to do the trick. After selecting an Item I'd display a form, when the user closed the form, the carousel was no longer rotating (or looping), however, one slight issue occurred-- two of the items appeared stacked on top of each other.

I want the items to appear in a carousel-like circle, but I just don't want them to rotate, because some of my users are finding it annoying.
