I am able to use the bindinglist() as a datasource for my winforms gridview. I set a timer to randomly update an item in my binding list and the changes are correctly reflecting on the grid. I am using the Onpropertychanged and iNotifyPropertyChanged events in my data class, so my grid is updating with the correct values when the underlying data changes.

I would like to make the cell momentarily change color when the data is changed in that cell. 

Is there a grid event that fires when the underlying data changes when using a bindinglist and the onpropertychanged notifiers?

I cannot seem to locate the correct grid event that fires when the data changes.

Hello,

So, I have a SplitContainer which contains checkboxes and stuff whose Enabled and Checked statuses will determine what Values will be written on the Database.
When the process to write to the DB begins, I make the Splitcontainer.Enabled = False so that the user will not change anything after the Submit button has already been pressed.
I notice that even though the togglebutton's enabled status is True, when its parent, the Splitcontainer has Enabled=False, the togglebutton itself goes to Enabled=False.
I didn't programme such behaviour, so am I right to assume that this is something that happens by default on Telerik controls?

If so, is there a way to globally disable it? On the normal Windows Forms Controls this doesn't exist and I am used to leveraging this behaviour.

Hi!

Can you please tell me how can I change the background color of dropdown list item with SetThemeValueOverride when the item is in mouseOver state?

And how can I identify the elements, primitives, properties in every case if I need to change something with SetThemeValueOverride? Is there a generic guideline?

Until now I used your Visual Style Builder, but in some specific cases it doesn't help.

e.g.: DropDownList has a ListView, but how can I access ListItems and their states (default, mouseOver, Disabled etc.) through the DropDownList element?

Thank you,
Sandor
