I have a telerik rad grid with two columns, 1. isconstraint, 2. Quantity
isconstraint is a bool which dislays true or false. quantity is int
My requirment is to convert 0's in the quantity column to an image or a color brush if the isconstraint is false.
I tried using IvalueConverter. I tried to pass the Isconstraint as a converterparameter.while running, it is bulding sucessfully, but not loading the page. can anyone help me out with this please. thank you very much. My code looks like this.
<telerik:GridViewDataColumn DataMemberBinding="{Binding LastQtyAvail}"
Width="130"
IsReadOnly="True" TextAlignment="Right" HeaderTextAlignment="Center">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image x:Name="img" Visibility="Visible" Source="{Binding LastQtyAvail,Converter={StaticResource QuantityToImageConverter},ConverterParameter={Binding IsConstraint}}" Width="100" Height="100"/>
<TextBlock Text="{Binding LastQtyAvail}">
</TextBlock>
</StackPanel>
<!--<Border BorderThickness="1"
CornerRadius="5"
VerticalAlignment="Top"
BorderBrush="Black"
Margin="0"
Background="{Binding LastQtyAvail,
Converter={StaticResource QuantityToImageConverter},ConverterParameter={Binding IsConstraint}}">
<Image x:Name="img" Visibility="Visible" Source="{Binding LastQtyAvail,Converter={StaticResource QuantityToImageConverter},ConverterParameter={Binding IsConstraint}}" Width="100" Height="100"/>
<TextBlock Text="{Binding LastQtyAvail}">
</TextBlock>
</Border>-->
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn DataMemberBinding="{Binding IsConstraint, Mode=TwoWay}" HeaderTextAlignment="Center"
IsGroupable="False" IsVisible="{Binding IsColumnVisibleToCustomer, Source={StaticResource PFOViewModel}}"
IsReadOnly="{Binding CanExecuteProductUpdateConstrain, Converter={StaticResource BooleanNotConverter}, Mode=OneWay}"
Background="#77ADD8E6"
Width="74" />
And the valueconverter cs file is
public class QuantityToImageConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
//string path = string.Empty;
//int result = (int)value;
//string falsePath = "/Brightstar.VSO;component/Assets/DataGrid/False.png";
//if (parameter == null)
//{
// //int imagePaths = Convert.parameter.ToString().Split('|');
// //if (imagePaths.Length == 2)
// //{
// // truePath = imagePaths[0];
// // falsePath = imagePaths[1];
// //}
//}
//if (parameter != null)
//{
// // int imagePaths = Convert.parameter.ToString().Split('|');
// int imagePaths = Convert.Parameter.Tostring().Split('1');
// if (imagePaths.Length == 2)
// {
// falsePath = imagePaths[1];
// }
//}
////if (result==0 && )
////{
////}
////else
////{
//// path = falsePath;
////}
Int32 id = System.Convert.ToInt32(value);
LinearGradientBrush brush = new LinearGradientBrush();
brush.StartPoint = new Point(0, 1);
brush.EndPoint = new Point(0, 0);
brush.GradientStops.Add(new GradientStop()
{
Color = Colors.White,
Offset = 0
});
brush.GradientStops.Add(new GradientStop()
{
Color = Color.FromArgb(
200,
System.Convert.ToByte((id * 103) % 256),
System.Convert.ToByte((id * 157) % 256),
System.Convert.ToByte((id * 233) % 256)
),
Offset = 1
});
return brush;
//ImageSourceConverter conv = new ImageSourceConverter();
//return conv.ConvertFromString(falsePath);
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return 0;
}
}
