I am implementing telerik's radschedular and loading resources in it with grouping functionality.
i have multiple docotrs and i want to distingvished their data by different colors.

Is there any mapping field for colors in ResourceMappingInfo class to map colors from resources object
for better understanding i m attaching some part of my code over here


        For i As Integer = 0 To resourceNames.Length - 1
            Resources.Add(New PanaceaBuisnessLayer.AppointmentResource(resourceNames(i), i + 1))
            Resources(0).Color = Color.Black
   Resources(1).Color = Color.Red
        Next i

        Dim resourceMappingInfo As New ResourceMappingInfo()
        resourceMappingInfo.Id = "Id"
        resourceMappingInfo.Name = "Name"
resourceMappingInfo.Color= ??????

        dataSource.ResourceProvider.Mapping = resourceMappingInfo
        dataSource.ResourceProvider.DataSource = Resources

        RadSchdAppView.GroupType = GroupType.Resource
        RadSchdAppView.DataSource = dataSource

Hi asif,

Thank you for writing.

Here, it is imporant how you will represent the color in the data table - as a string or as something else. In addition, you should add custom mapping for the color property of the resource. The mapping for the color should be equal to the name of the field in the data table that represents the color. If the field in the data table has a string value, you should convert this value to color. For that purpose you should to create a converter callback functions that are set to the custom mapping object.
ResourceMappingInfo resourceMappingInfo = new ResourceMappingInfo();
SchedulerMapping colorMapping = new SchedulerMapping("Color", "Color");
colorMapping.ConvertToDataSource = new ConvertCallback(this.ConvertColorToDataSource);
colorMapping.ConvertToScheduler = new ConvertCallback(this.ConvertColorToScheduler);
 
resourceMappingInfo.Mappings.Add(colorMapping);
 
 
private object ConvertColorToScheduler(object obj)
{
    //return Color as an object
    return Color.White;
}
 
private object ConvertColorToDataSource(object obj)
{
    //return Color as a string
    return string.Empty;
}

In case that you have further question, feel free to write back.
