I have a radDropDownButton that has a border with a corner radius as the DropDownContent - the border corner radius is applied, however I cannot seem to find where to remove the 1 pixel border that is always around the DropDownContent.  Is this possible?

I am having trouble changing the scrollbar style for RadCombobox, I have tried several things and nothing works, I am sure i am missing something because it works on another project.

-- Project in which it is working --
I am not using implicit style here, i have created new scroll bar style:
<Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}">

I have created combobox style:
<Style x:Key="RadComboBoxStyle1" TargetType="{x:Type telerik:RadComboBox}">

and i see the new scroll bar style

-- not working --
In the other project i have the same style for scrollbar and same style for Combo box, the only difference is that i am using implicit styles
 <Style TargetType="{x:Type telerik:RadComboBox}" BasedOn="{StaticResource RadComboBoxStyle}">


the combo box style was suing office manager theme and i commented that out, for the project where it is working if i do not comment that it does not work, but for this project that does not help.
 <telerik:StyleManager.Theme>
                                    <telerik:Office_BlackTheme/>
                                </telerik:StyleManager.Theme>

Hi,

I have a RadDataForm using Windows8Theme (although the theme doesn't seem to matter) with the following definition:



The result is the attached image. Notice how username and e-mail fields are of a different size than the other field.

Could you kindly shed some light to this?

Hi,
I am having an interesting issue with nested GridViews using row details.
I need to be able to double click on rows in both the child and parent GridView and handle them differently.
But there seems to be an odd behavior where when I double click on the child row the MouseDoubleClickEvent gets raised on the child row first, then a different MouseDoubleClickEvent gets raised on the parent row. Event if I set the first event to being handled a separate event is raised on the parent row.
The event handlers are being added on the RowLoaded event for both the child and parent GridViews.



Kind Regards,

Ryan

Hi

I've noticed that in 2014.3.1021 there have been some performance enhancements to UpdateAllFields.  I'm not entirely sure what they are, but if I was to guess I'd say the document is no longer being layed out, mesaured and arranged after each field update.

This has, sadly, broken one of my custom fields.

I have a sort-of-cross reference field - it returns the page number of a custom AnnotationRangeStart.  It does this in basically the same way as PageField.

Following the update to this version, the page number is always returned as '1' during UpdateAllFields.  This seems to be because the layout only reports a single SectionLayoutBox in the DocumentLayoutBox.

I see from the PageField source two internal virtual methods that you use to workaround this issue: SaveState and RestoreState.  As these are internal and not protected internal, I can't do the same.

My current workaround is to run Document.UpdateLayout() while this field is updating, which isn't ideal.  Do you have any better ideas, or would you consider changing the accessibility of these internal state management methods?

Hi,
i can not remove first record in radgridview with RadGridView.Items.RemoveAt(0);
help me please , tanks

Quick question.

How do I replace the standard GridViewGroupRow with a custom derived class?

Hello,

In my project, I need to show a gantview which the user can modify tasks (duration, start, end), with field or with the behavior of the component (drag and drop). The problem is when the user put a start equal to the end for a task, these task is transform to milestone, with a different style and different behavior(including the deactivation of expansion of the task by left or right), which can disrupt the user. How can I keep the style/behavior of the task even start and end of the task is equal ? (it's not important if the tasks have a minimum size)

Thanks for Your Help

Hi,
We have an usercontrol that it used to generate several different grids in a same window.
We noticed that when we have 2 or more grids  in a window, the load time begins grow and the performance drops.

Our control uses a DataTable to generate the data because each grid could have different number of columns, here is the way we make the assignment:

dataGrid.ItemsSource = data.DefaultView;

Our problem its related with this line, because this operation its taking between 150 and 200 milliseconds, that seems good for a single grid, but when we have several of this it could take more than a second or two to load a window, which is not acceptable for our customer.

It's there a way to improve this?

Just in case, we are taking in care your tips and tricks help topic
We are using the 2011 Q3 telerik version.

Thanks!

Ok, I'm troubleshooting an issue in our app.  We've got several RadGridViews, but in this one particular view, when you click on any column header to sort the grid, all of the grid data disappers.  the data remains invisible if the column state is ascending or descending, but reappears if you toggle the column back to no sort.

Obviously we are doing something wrong in this specific RadGrid.  I've tried to copy what is going on in our other grid views but I haven't figured out the difference yet.  I figure I can't be the first person to have seen this behavior, so if someone else has seen this can they point me in the right direction towards fixing this problem?  Thanks!
