Hi,

    I'm using  in GridView to keep the input away from unexpected errors. But I encountered a tiny defect. The error messages only display when mouse hovering on the top-right corner (it's a red small triangle out there). This makes the user a little trouble when checking the message because he has to move his mouse in a  pretty accurate location. In fact, users usually prefer to get the error tip when the mouse enters the cell. there any methods to implement this?

 

Thank you!

I wish to make a RangdSpline series with a gradient. Similar to what is done in the SurfaceSeries3D

Is this possible in 2D?

This is a difficult one, I think. If you look at one of the attached screenshots, some of the labels are adjacent to the axis as they should be, but some are quite distant. Sometimes they will all be correct except a few, sometimes they are all fine, and sometimes they are all wrong.

 

The problem seems to especially manifest when that the chart is bound to changes, and the new values on the labels are not included in the original values. For example the first screenshot has values at each 100 step, and when the data point changes from 400 to 200, the x100 values which were already on the axis are correct but the new x50 values are placed incorrectly. It isn't that straightforward of course... for example, often labels which weren't there originally are added fine. 

 

The chart is fairly basic. It is a single fixed series bound to a list of data point objects. When we change the data we completely replace the list rather than try to use an observable collection.

Hello,

we're using your RadExpression editor in our application. We create the expressions using the editor and then we save them. At a
later stage we parse them using the editor again, but we would like to use the parsing functionality without a dependence on WPF.
Is there anyway to do that with any of your products?

public static List<T> Filter<T>(IList<T> items, string filter) where T : new()
        {
            var result = new List<T>();
 
            try
            {
                var editor = new RadExpressionEditor();
                editor.Item = new T();
                Expression exprResult;
                var isSuccess = editor.TryParse(filter, out exprResult);
 
                if (isSuccess)
                {
                    var expr1 = (Expression<Func<T, bool>>)exprResult;
                    var func = expr1.Compile();
                    result = items.Where(func).ToList();
                }
            }
            catch (Exception)
            {
                
            }
 
            return result;
        }

We have multiple grids (RadGridView and RadTreeListView) visible at the same time in our application.  We would like for the unfocused grid(s) to have their selected cells appear unfocused.  This works when the SelectionUnit is FullRow, but doesn’t otherwise, and the EnableLostFocusSelectedState doesn’t seem to have an effect.  Is there a way to make this work with SelectionUnit=”Cell”?

Hi,

I recently noticed some strange behaviour when using the search panel of the GridView.

In our application the AvalonDock control (Xceed) is used for the UI. Each time the user selects a program in the menu, a UserControl is opened in a new docked document of the AvalonDock control.

Now for the strange behaviour: 

• Program A with GridViewA is launched
• A search criteria is entered, GridViewA shows the result (so far so good)
• Program B with GridViewB is launched.  For GridViewB the search panel is hidden by default
• Return to the docked document containing program A => the search panel is also hidden
• Pressing CTRL+F opens the search panel for GridViewA, but no search criteria is shown => the displayed data is limited to the search criteria,  impossible to view all records in GridViewA !!

Any help would be much appreciated !

Best Regards,
Hans

Hello,
We're using RadListbox to display elements of varying height. Some of them are small, some are large.
The default behaviour of the scroll mechanism seems to work based on the whole items.
For example if the user clicks with his mouse on the up or down arrow of the scrollbar (vertical one) he gets shifted by the length of the visible item. Gets shifted more for bigger items.
Also, when doing

var v = radlistboxChat.ChildrenOfType<ScrollViewer>();
foreach (var q in v)
{
   q.ScrollToBottom();
}

to programatically scroll down to the last item, often we observe that in case of larger items, the item gets positioned at the top of the RadListbox, leaving an empty space below. My guess is that it happens because the previous item is also big, and if this was to scroll to the bottom, it would show the last element at the bottom but the previous element would not fit the remaining space and would need to be displayed partially, which the listbox doesnt want to do.

We found a simple solution to the problem. We do something like this:

<ScrollViewer HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto">
    <telerik:RadListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" >
</ScrollViewer>

This puts the listbox into a scrollviewer that works as expected. It operates on pixel lenghts rather than item height's, so the scrolling is smooth and scrolltobottom works as expected.
However, there is a very weird behaviour observed with this solution.
Populating items and refreshing the listbox becomes significantly longer. An average sized list of items refreshed in 90 ms without the additional scrollviewer, but it took 1800 ms to do the same with the scrollviewer, That's 20 times longer. Our requirements indicate that our list needs to refresh quickly, since its often refreshed.

My question to you is:
Can I make the scrollbar of the listbox behave like in our solution while and maintain it's original speed?
thanks.

Good day.

National characters in RadPasswordBox are displayed as a 
question mark, if the password is inserted through the clipboard.

This behavior is not observed in either RadWatermarkTextBox or PasswordBox.

Please tell me how to solve this problem.

Hello

I'm using RadGridView and try to handle the MouseDoubleClick-Event. My problem is to get the RadGridCell the user has double-clicked on.

Can you help me with this?

Thanks!

Hey. I use RadTileView and this is a great solution. Could you tell me how I can adjust the vertical Tiles distribution instead of the horizontal one? And how can I set margin=0 for Tiles?
