There are several approaches that you can take in order to achieve the desired behavior:
1.You can set the RowDetailsVisibilityMode
property of the RadGridView to Collapsed or Hidden.
2.Setting the IsSynchronizedWithCurrentItem
property to true
will change the position of the arrow based on the current item.
3.In order to keep the default look of the RadGridView and remove the indicator, you have to edit the Control Templates of the control. You can find more information on the following articles from our documentation page - RadGridView Styles and Templates
and Using Implicit Styles.
