I have a datagrid which uses a wcf serrvice to get populated.
datagrid.itemssource = e.Result;
Now i have to modify the data of column of int datatype into images based on the values.
For Example: If r = 1, show correct icon else show wrong Icon.
This should be done at run-time.
If there is some sample code, it would be helpful..
Thank You

I assume the return value (e.Result) from your WCF call is a list object (or a object Array)? When you set the DataGrid.ItemSource = e.Result, each UIElement in the DataGrid will automatically has a DataContext set which is the Data Object for that particular row. So you can access to it.
If you set a Image control for a column in the Data Template. You hook up a Loaded event handler for it. On Loaded event handler , you get the Data for that Row, do some checking then set the Image.Source accordingly:
private void Image_Loaded(object sender, RoutedEventArgs e) { Image i = sender as Image; MyDataObject d = i.DataContext as MyDataObject;
if(MyDataObject.Field1 == "something")
{ i.Source = ImageURL;
} }
