Hello is there any way to make the checkbox appear darker, bold in side the gridview? I am not sure the property to edit.

<Style x:Key="CheckBoxColumn" TargetType="{x:Type telerik:GridViewCell}">
               <Setter Property="FontWeight" Value="Bold"/>
           </Style>
 
 
 
<telerik:GridViewCheckBoxColumn EditorStyle="{StaticResource CheckBoxColumn}"  Header="Eligibility" IsReadOnly="True" DataMemberBinding="{Binding Verified}">
                                   <telerik:GridViewCheckBoxColumn.CellStyle>
                                       <Style TargetType="telerik:GridViewCell">
                                           <Setter Property="Background" Value="{Binding VerificationStatus, Converter={StaticResource MyConverter2}}" />
                                       </Style>
                                   </telerik:GridViewCheckBoxColumn.CellStyle>
                               </telerik:GridViewCheckBoxColumn>
                               

The above code did not do it.

Thanks,
S

Hello Sean,

 

The standard GridViewCheckBoxColumn uses a GridViewCheckBox and the standard CheckBox control as its editor. If you want to bold the content of a CheckBox you may predefine the CellTemplate for a standard column and manually set the FontWeight of the CheckBox:


<telerik:RadGridView  Margin="40,40,168,90" AutoGenerateColumns="False" ItemsSource="{Binding Collection}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Property2}">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox  telerik:StyleManager.Theme="Office_Black" FontWeight="Bold" Content="{Binding Property2}" IsChecked="{Binding Property2}"/>
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellTemplate>
                         
                    </telerik:GridViewDataColumn>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>


As an alternative you may also define a style targeted at a GridViewCell and manipulate its appearance from there:


<Window.Resources>
    <Style x:Key="ss" TargetType="telerik:GridViewCell">
        <Setter Property="Background" Value="Red"/>
        <Setter Property="FontWeight" Value="Bold"/>
        </Style>
    </Window.Resources>
    <Grid x:Name="LayoutRoot" DataContext="{Binding Source={StaticResource SampleDataSource}}">
        <telerik:RadGridView  Margin="40,40,168,90" AutoGenerateColumns="False" ItemsSource="{Binding Collection}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn CellStyle="{StaticResource ss}" DataMemberBinding="{Binding Property2}">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox  telerik:StyleManager.Theme="Office_Black" Content="{Binding Property2}" IsChecked="{Binding Property2}"/>
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellTemplate>
                         
                    </telerik:GridViewDataColumn>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>
    </Grid>
</Window>


Furthermore the recommended approach to a apply a style based on underlying property value is through StyleSelectors, please check our online demos for further reference.

I did something like this originally but it was impossible to prevent the user from clicking the contents of the checkbox in the column. Is that possible to do? When I did something similar to this they were able to check the checkbox still:

<telerik:GridViewDataColumn Header="Confirmed" IsReadOnly="True">
                                 <telerik:GridViewDataColumn.CellTemplate>
                                     <DataTemplate>
                                         <CheckBox telerik:StyleManager.Theme="Office_Black" FontWeight="Bold" Content="{Binding ConfirmedStatus}" IsChecked="{Binding ConfirmedStatus}"/>
                                     </DataTemplate>
                             </telerik:GridViewDataColumn.CellTemplate>
                                 <telerik:GridViewDataColumn.CellStyle>
                                     <Style TargetType="telerik:GridViewCell">
                                         <Setter Property="Background" Value="{Binding ConfirmedStatus, Converter={StaticResource ConStatConverter}}" />
                                     </Style>
                                 </telerik:GridViewDataColumn.CellStyle>
                             </telerik:GridViewDataColumn>

Hi Sean,

 

You may use a GridViewCheckBoxColumn instead that will listen for the IsReadOnlyBinding property and will become non-editable if it is set to "True":


<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding Property2}" IsReadOnlyBinding="{Binding Property2}"/>

I tried that but the checkbox still appears "grayed-out". Is there a way around this?

Thanks,

Hello Sean,

 

GridViewCheckBox is gray-colored by design when the cell is not in Edit mode. You may change this through edit the template of a GridViewCheckBox and predefine the brushes which are used by default.
In this way you may configure it to meet up your personal requirements.



All the best,

I think there is a bug in this. If AutoSelectOnEdit is true then the checkbox is designed to be set/unset with a single click, therefore it should not be gray.

This behavior is by design. The CheckBox will be gray in none-edit mode nevertheless of the AutoSelectOnEdit property. The difference here is that the CheckBox can be check/uncheck with a single click.

Hi Vanya,

I have this GridViewCheckBox column type and I want to collapse just the Checkbox control for some of the rows, based on some derived from other columns in grid.

Now, I used the CellStyleSelector of GridViewCheckBoxColumn, for my Style selector  that I created I am not able to set the TargetType as GridViewCheckBox, it fails saying the type does not match with type of element 'GridViewCell'.

I assume that CellStyleSelector will apply only to GridViewCell, what style selector should I use to apply to the GridViewCheckBox only?

Please see the attachment for implemented code and error.
