[WPF] Use IValueConverter but hide the value in cell

Hi,

I have a column with a range of age.

I'm using a Convert to set a background color to a single cell of my column 'age'...

I would color the cell but hide the numeric value.

I can set a custom background, but I can't hide the value.

How can I make this?

This is my code:

XAML:

public class ColorToCell : IValueConverter

{

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

{

int tempValue = int.Parse(value.ToString());

string tempString = "Red";

if (tempValue >= 0 && tempValue <= 20)

tempString = "#FF0000";

if (tempValue > 20 && tempValue <= 40)

tempString = "#F09300";

if (tempValue > 40 && tempValue <= 60)

tempString = "#EDDF00";

if (tempValue > 60 && tempValue <= 80)

tempString = "#CC00FF55";

if (tempValue > 80 && tempValue <= 100)

tempString = "#85AB00";

SolidColorBrush brush = new SolidColorBrush();

BrushConverter conv = new BrushConverter();

brush = conv.ConvertFromString(tempString) as SolidColorBrush;

return brush;

}

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)

{

return DependencyProperty.UnsetValue;

}

Thanks.

Both solution is fine but try to minimize your bindings/converter call else it will surely lead to performance degradation :)

Hi,
i resolved with this two solutions:

I° solution: create a rectangle where bing my value with converter:

II° solution: set color of text as background color of cell:

What do you think?

<DataGridTemplateColumn>

<DataGridTemplateColumn.CellTemplate >

<DataTemplate>

<TextBlock Text="Akhil">TextBlock>

DataTemplate>

DataGridTemplateColumn.CellTemplate>

<DataGridTemplateColumn.CellStyle>

<Style TargetType="DataGridCell">

<Setter Property="BorderThickness" Value="2" >Setter>

<Setter Property="BorderBrush" Value="Black" >Setter>

DataGridTemplateColumn.CellStyle>

DataGridTemplateColumn>

Sorry, but: "The property 'BorderThickness' was not found in type 'TextBlock'."

Instead of DataGridTextColumn Create DataGridTmplateColumn inside that create cell style and in that Create TextBox then You can use trigger to set Value of text as " " on bases of you color or you can use multibinding
