[Solved] Doubt on RadGridView Control's property

[Ashok kumar]

I am newbie to RadControls. I have to work with RadGridView. While analysing the code, I found one property called ColumnBackground with peculiar value ={x:Null}: Can anybody learn me what does it mean? I am sending the code part also.

                <grid:RadGridView x:Name="GridView1" 

                                      CanUserResizeColumns="False" 

                                      MultipleSelect="True"  

                                      DataLoadMode="Asynchronous"  

                                      AreRowDetailsFrozen="True" 

                                      RowDetailsVisibilityMode="VisibleWhenSelected" 

                                      RowDetailsTemplate="{StaticResource TestRowDetailsTemplate}" 

                                      SelectionChanged="GridView1_SelectionChanged" 

                                      ItemsSource="{Binding TestAwards, Mode=TwoWay}" 

                                      IsReadOnly="True" 

                                      AutoGenerateColumns="False"  

                                      ColumnsWidthMode="Fill" 

                                      CanUserFreezeColumns="False" 

                                      UseAlternateRowStyle="True" 

                                      ColumnBackground="{x:Null}"

                                      ShowGroupPanel="False" 

                                      RowIndicatorVisibility="Collapsed" 

                                      ScrollMode="RealTime"

                                      Style="{StaticResource RadGridViewSettings}"

                                      IsEnabled="False"

                                      Background="Transparent">

Thanks in advance.

Hello Ashok,

There are multiple ways of setting a color in XAML. You can set a named color, a hex value, or no value at all. In the latter case the {x:Null} stands for just that.

Now the difference between a Border (for instance) with Transparent color and a border with {x:Null} color is that in the first case the Border has a background which is invisible in the second case there is no background.

One of the possible issues you might encounter is that you will not be able to click on an element with {x:Null} as background - there is nothing to click on, while as if the color is Transparent you will be able to click.

I hope this brings some clarity to your question.
