There is a lot of code in this post. Please pardon the length.

I've got a RadGridView control that uses a custom StyleSelector. There is a particular condition in my data which, when true, I want to flag by changing the color of the text to Red. I also need the background color of the currently selected row (the entire row ) to change. For some reason, however, the neither of these effects is working for me, though I did have the color changes working at one time.

I had to modify the template used by the RadGridView and GridViewRow classes in order to implement "day mode" and "night mode". The idea is that the colors change to a darker scheme at night time and a brighter scheme during the day. The app is to be used by police officers in patrol cars, so the color changes are important.

Here is the XAML in App.xaml for the RadGridView stuff:

<Style TargetType="{x:Type telerik:GridViewCell}">

<Setter Property="BorderBrush" Value="{DynamicResource DataBorder}" />

<Setter Property="Background" Value="{DynamicResource DataBackground}" />

<Setter Property="Foreground" Value="{DynamicResource DataForeground}" />

</Style>

<Style TargetType="{x:Type telerik:GridViewRow}">

<Setter Property="IsTabStop" Value="False"/>

<Setter Property="Template">

I really need the color changes to work. I'm pretty sure I screwed something up in the templates, but I have no idea what. Can someone look at this and see if they can figure it out?

Thanks

SelectionForegroundColors.zip

Hi Tony,

If you want to change the Foreground property of the row why not directly use its Foreground property of the row?. As described in our documentation if you want to change Background of the selected row you should modify the Border element named Background_Selected. If you want to change the Foreground of the selected row you may animate the DataCellsPresenter which is responsible for displaying GridViewCell. On a row basis you do not need to deal with the Foreground property of the cell. I am attaching you small sample project which demonstrates how to achieve this. Please have a look at it and if you have any additional questions let us know. Furthermore you may also submit a support ticket where you may attach your demo where we can see what is wrong.

Vanya:

I just found this response. I would take a look at your code, but the link doesn't work!

Also, I am modifying the Foreground property, and it's not changing the color of the text in the cells. I think I have something conflicting with something else in my templates, but I don't know what. I have to find it.

It's important that the foreground color of the rows which match a specific condition be changed. The condition is a bool property of the data in the column. I had created a custom RowStyleSelector class which used to work, but it got broken somewhere. I'm about to go into my code and try by trial and error to find the style that broke the display. This ought to be fun.

I've found the issue: The definition of my telerik:DataCellsPresenter was conflicting with the changes I was trying to make to the Foreground property of the GridViewRow in the styles I was using with the custom RowStyleSelector class. When I removed the definition and put the changes I was trying to make into the GridViewRow template, then everything worked.

Tony

PS: Actually, it wasn't quite that simple. The foreground colors worked, but the change to Night Mode didn't. I had to restore the DataCellsPresenter template and delete the setters for the Foreground property from that template and from my template for the GridViewCell class. Once I did that, the Night Mode and Foreground changes took effect.

I've got the SelectionUnit property on my RadGridView controls set to FullRow, but only the first column is selected. I suspect this is another problem in my GridViewRow or GridViewCell or DataCellsPresenter templates, or some combination there-of. Also, I changed the Background property of the Background_Selected element in the GridViewRow template and that didn't have any effect. Back to the trial and error stuff.

PPS: OK, I deleted the GridViewCell template and the entire row gets selected. The color isn't the one I want, and Night Mode is broken. I'm setting the Background property of the GridViewRow to my DynamicResource but it's not changing when I go to night mode. What am I doing wrong now?

PPPS: I've got everything working. I totally deleted the tempate for the GridViewCell type. In order to get the entire row to show selected and get Night Mode working right, I had to do 2 things:

1. In 2 of the RadGridView controls in my program, I'm using a custom RowStyleSelector class. I set the Background property to my DynamicResource in the styles associated with these controls and that worked.

2. In the other 2 RadGridView controls in my program, I set the RowStyle property of the RadGridView, as shown in this posting.

The only problem I have now is the colors I've chosen for the selected row in the RadGridView aren't showing. Instead, they are showing up as a shade of yellow. Time to figure out what's going on there.

Hi Vanya,

I'm just creating a control with a RadGridView inside that allow users edit the cells values. I expect that, when user inserts a value, the application checks all row values and change cell's background where the cell's value isn't value. By example, imagine the row:

Name | Age | AllowDrive | Children (nº)

And a user named "John", 25, Yes, 1

If I change John's age to 17, Allow Drive's value (Yes) isn't correct and background color must be red.

If I change John's age to 5, Allow Drive's value (Yes) isn't correct and background color must be red, and John cannot have a children: the cell must be red. If user changes now values (children = 0 or Allow Drive = false), the grid must call to validator and now the background must be white (or the default value).

How can I implemente something like this?

Like a first approach (that only changes the changed cell's color) I'm trying using a StyleSelector and giving it programatically (the datasource is dynamic, a dataset with values), with something like this:

	    // Load Cell Styles after set binding
            SampleStyleSelector cellStyle = new SampleStyleSelector();
        
            foreach(GridViewDataColumn column in radGridView1.Columns)
            {
                column.CellStyleSelector = cellStyle;
            }

And my SampleStyleSelector is:

 public class SampleStyleSelector : StyleSelector
        {
           public override Style SelectStyle( object item, DependencyObject container )
           {
               string value = string.Empty;
 
               if (null != ((Telerik.Windows.Controls.GridView.GridViewCell)container).Value)
               {
                   value = ((Telerik.Windows.Controls.GridView.GridViewCell)container).Value.ToString();
               }              
 
               if (value.Length > 3)
               {
                   return this.RedStyle;                   
               }
               else
               {
                   return this.GreenStyle;
               }
            }
 
       public SampleStyleSelector()       
       {
           Style s = new Style(typeof(Telerik.Windows.Controls.GridView.GridViewCell));
           s.RegisterName("Background", Brushes.Green);
 
           GreenStyle = s;
 
           Style s2 = new Style(typeof(Telerik.Windows.Controls.GridView.GridViewCell));
           s2.RegisterName("Background", Brushes.Red);
 
           RedStyle = s2;
 
       }
 
       public Style RedStyle
       {
           get;
           set;
       }
 
           public Style GreenStyle
           {
               get;
               set;
           }       
        }

but when user changes the value, grid doesn't show changes.

Thanks a lot!

Miguel.
