RadGridView supports alternating row color mode which allows you to easily distinguish one row from another.
In order to enable the feature, you should set the EnableAlternatingRowColor property to true:
Copy[C#] Enable alternating row color
this.radGridView1.EnableAlternatingRowColor = true;
Copy[VB.NET] Enable alternating row color
Me.RadGridView1.EnableAlternatingRowColor = True
In order to change the default alternating row color, set the AlternatingRowColor property:
Copy[C#] Changing the alternating row color
((GridTableElement)this.radGridView1.TableElement).AlternatingRowColor = Color.Yellow;
Copy[VB.NET] Changing the alternating row color
CType(Me.RadGridView1.TableElement, GridTableElement).AlternatingRowColor = Color.Yellow
The result is shown on the screenshot below:
