When I AutoFit() my diagram, I want all nodes to be visible on screen. However, this is impossible when the diagram is too large. The zooming restriction gets in the way.

I want to be able to zoom out until all nodes are visible on screen, no matter the size of the diagram! It doesn't matter if the rendering of the nodes suffers. In a complex diagram, I must be able to see all nodes to get an overview of its structure. This is absolutely crucial for our application so please provide us with a patch/workaround! Thanks.

I really don't understand why the zooming works this way. I get the same result if I set the Zoom to 0.1 or 0.05...

Hello,

I'm trying to implement a "find" feature where the user can enter a value in a textbox (outside of the grid) then click a button to find the row that matches the search criteria.  I'm able to programmatically set the selectitem on the grid successfully, but if the item is not in the current scroll region the user has to scroll down to to the item.  Is there a way to ensure that the selected item is always in view?  Also, I should mention that we are using MVVM, so there is no code behind.

Thanks.

Hello,

I like to have the width of the WeekView always equal to the width of the current parrent. But as soon as I have more Appointments ScheduleView is displaying a horizontal scrollbar and I have to scroll horizontally to see the last days of the week. (See attached Screens)

Is there an option to shrink the Appointments in width so I see always the complete week without scrolling horizontally?

Kind regards,

Markus

Hello,

I have RadDiagram with some shapes

I tried to arrange the shapes to be one on/under other and using send backward and bring forward actions, but there is a bug in that actions

The problem is that if I clicked send backward when the shape is already in backward and then click bring to front, I have to click the same times that I clicked send backward before (if I clicked 3 times after the shape was in backward, I have to click 3 times till the shape will bring to front)

I saw the bug also in telerik demos

How can I fix this bug?

Thanks

Is it possible to overwrite the RadGridView Search logic and implement a custom search logic ?
My Problem is that the search works only good on text. In our grid we have columns with Date and / or columns with numbers. The search performs really poor on these types. 

I attached two gif files to showcase my problem.

I have the following implicit style:

    <Style TargetType="telerik:GridViewCell" BasedOn="{StaticResource GridViewCellStyle}">
        <Setter Property="FontFamily" Value="Segoe UI" />
        <Setter Property="FontSize" Value="18" />
        <Setter Property="Foreground" Value="Green" />
    </Style>

However, only the foreground color changes - all font settings are ignored. 

Searched this forum, I don't think it is Theme related, but I am using the Crystal theme

Hi, I am having an issue with a standalone RadMultiColumnComboBox.  It needs to be populated differently each time I select a different entity (User) from a RadGridView.  As I understand it the only way to do this is with events. 

The problem is that I run into an exception when I try to clear the selected items from the MCCB (basically, I need to reset it), and add the new selections.  I get various ObservableCollection changed event exceptions.  

What is the correct way to do this to avoid these type of exceptions? 

Thanks,

Ian

 

Here is the code I use so far: 

 

 

Here is an example of the exceptions I am getting:

I've ready through the migration guide, overview, and DragDropPayloadManager guides, but there is still not enough information to migrate my existing code.Even the migration guide isn't sure which event maps to which event (see attached photo).

Can someone familiar with making the migration help me port over this code since basically everything has changed?
