Hey there! I'm just doing a bit of scouting at the moment for a new desktop app we're looking to write -- probably a WinForms C# app. This app will need as one of its features to be able to edit XML and CSharp code snippets.

Since RichTextEditor is already in our toolbox of toys -- but I haven't worked with it previously -- I was wondering, is there any way to make it behave as close as possible to a Visual Studio style code edit window?

I like the look of the code blocks ("InsertCodeBlock()" function) in RTE but those appear to be read-only. Ideally I'd want the entire edit window to look like the code block (syntax highlighting for the desired language) but not do any of the RTF type things (bolding, italics, etc.)

Just thought I'd pick the communities thoughts to see if this was even feasible before sinking too much time going down a dead end. Thanks!

Hello guys,

There is a way to creating a radspin editor like in the picture attached?

Hey guys, Is there a way to show some clue on a page that have invalidated controls? 

I'm currently using error provider to show errors on controls, I've tried using it on the page but it don't have good location, and I need a generic solution because I use a generic validator to see if the controls has value.

I'm currently using 2015.1.225.40 version and sorry for bad english. Thanks in advance.

I'm not sure if someone will help me with this, considering the version. We are using radcontrols for winforms Q1 2009 SP1 (2009.1.9.414). 

I have a MDI Parent, and several mdi children. One MDI Child form with a RadGridView on it. The form works fine, and performs as expected. I use events like CellBeginEdit and CellEndEdit to make changes to the database. The gridview is bound to a BindingList<myCustomClass>. When I edit directly in the grid I update to database on CellEndEdit the entire object. something like this:

myCustomClass objToUpdate = (myCustomClass)RadGridView1.Rows[e.RowIndex].DataBoundItem;

Debug.WriteLine("id: " + objToUpdate.Id);

Debug.WriteLine("Priority: " + objToUpdate.Priority);

db.UpdateCustomClass(objToUpdate); 

However here is the problem:
If I do one update, change to another MDI Child form, and change back to the form in question, the objects are not updated correct. I can see in the debug that the Id property is correct, but the priority (Int32) have the old value. Since Priority is Int32, I can change with both keyboard and numeric up/down. But if I change priority using numeric up/down editor it works. If I change priority from 1 to 2 with keyboard and press Enter, the value does not change, but if I try to edit again, the numeric up/down have value 2...

If I just open the form and select a row, change back and forth, and do an update, everything works. It is just if I make a change to the datasource before changin forms the problem occurs. 

I have tried to deselect currentRow when form1 is deactivated, so that when I come back I have to select the row again, but does not work. 

clearing bindinglist og populating grid again does not work either. I have to restart the form.

Any help greatly appreciated.. :-| 

Hello,

Im new into Telerik UI and I have a simple question:

How to remove a "Custom" filter option/element from filters menu on the top of all radGridView columns. 

Thanks in advance

     I have a RadDataFilter linked to a RadDataGrid which is functioning as desired.  I have a RadChartView (Bar Chart) that is a summary of what is being displayed in the Grid.  When I click a bar in the bar chart, I am populating the filter with a string that will filter the grid on only the rows that are related to the Bar.

Everything in this scenario is working, in that I get the filter looking correctly, based on the bar I clicked and the grid properly filtering.  The issue is that the filter item is DataFilterComboDescriptorItem and it is not displaying the correct value in the dropdown for the item specified.  It is basically displaying the last value ever selected, regardless of if I clear the filter.  

How is the value of a DataFilterComboDescriptorItem set when a RadDataFilter.Expression is manually assigned which affects that item?

Thoughts?

Here is my code:
