Hi Admin,

I have the same problem that Foreground is not applied to GridViewComboBoxColumn when I using RowStyleSelector.
And I tried to bind ItemsSource with "ItemsSourceBinding".
The style of Foreground is applied only data is loaded or scrolling data,
but it do not work when I turning page.
The style wasn't changed (as the same as previous page).
However,Background worked fine, and other columns worked as expected.

I paste my code segment following.
Is there any wrong with my code?

Code of XMAL:

<Grid.Resources>

<Style x:Key="Unfixed" TargetType="telerik:GridViewRow" />

<Style x:Key="Fixed" TargetType="telerik:GridViewRow" >

<Setter Property="Foreground" Value="#FF909090" />

</Style>

<styleSelector:FixStatusConverter x:Key="FixStatusConverter" />

<styleSelector:ConditionalStyleSelector x:Key="FixStatusStyleSelector" ConditionConverter="{StaticResource FixStatusConverter}">

<styleSelector:ConditionalStyleSelector.Rules>

<styleSelector:ConditionalStyleRule Style="{StaticResource Fixed}" Value="True"/>

<styleSelector:ConditionalStyleRule Style="{StaticResource Unfixed}" Value="False"/>

</styleSelector:ConditionalStyleSelector.Rules>

</styleSelector:ConditionalStyleSelector>

</Grid.Resources

>

...

<telerik:RadDataPager x:Name="RadDataPager" Source="{Binding Items, ElementName=GridView}" NumericButtonCount="7" IsTotalItemCountFixed="True" DisplayMode="All" ... />

...

<telerik:RadGridView x:Name="GridView" RowStyleSelector="{StaticResource FixStatusStyleSelector}" ...>

...

<telerik:GridViewComboBoxColumn UniqueName="PurClassID" DisplayMemberPath="PurClassName" SelectedValueMemberPath="PurClassID" DataMemberBinding="{Binding PurClassID}"

ItemsSourceBinding="{Binding PurClassList, Source={StaticResource PurClassListProvider}}" IsReadOnly="True"/>

....

Code of PurClassListProvider:

public class PurClassListProvider

{

private List<PurClass> purClassList ;

public PurClassListProvider()

{

... // Create purClassList by using DomainContext

}

private void GetPurClasses_Completed(object sender, EventArgs e)

{

... // Set purClassList using values obtained from server

}

public List<PurClass> PurClassList

{

get

{

return purClassList;

}

public class PurClass

{

public string PurClassID {get; set;}

public string PurClassName {get;set;}

}

Best regards,
Niwa

Hey Pavel,

I am looking for the RowStyleSupport for my Project for which i am continously try to figure out how to fix row color on certain values i insert in it using converter for here i am adding my converter with xaml and codebehind using Viewmodel,
Could you please assist us how to provide row selector on certain values, Here am trying to get rowcolor orange when ClientStatus is Existing and IsValid column is false.

Here i am using constants for Clients status when ever these values passed orange color will return through converter, now i am looking how to to apply rowstyle selector on View and CodeBehind.

Please Look into it.
Thanks

Hello,

You can create a rowstyle selector of yours and set it for the rows - something like :

public class MyStyleSelector : StyleSelector

{

public override Style SelectStyle(object item, DependencyObject container)

{

Style style = new Style();

style.TargetType = typeof(GridViewRow);

Brush brush = null;

if (!((MyItem)item).IsValid && ((MyItem)item).ClientStatus == "Existing")

{

brush = new SolidColorBrush(Colors.Orange);

}

else

{

brush = new SolidColorBrush(Colors.Transparent);

}

style.Setters.Add(new Setter(Control.BackgroundProperty,brush));

return style;

}

for illustrative purposes this code is based on the following simpidfied data item :

public class MyItem

{

public string ClientStatus { get; set; }

public bool IsValid { get; set; }

}

* You will have to adapt it to your data items a little bit.
