I am creating an xamgrid in c#, there's no xaml at all. How can I add a button to a column purely through c#? Or even hyperlinked text if this is easier? Please be explicit about every small detail as I'm new to this!
Basically I am creating multiple grids with dynamic columns based on a set of configuration data so I have done everything in c# to create/build/bind grid. I have seen examples for creating data templates in xaml with button controsl within them, but cannot work out how to do this from c#.
Thanks.
Hi,
Basically you'd have to use a xamlReader to read in your DataTempate:

As for actually executing code on the Button, i'd recommend using a custom RowCommand
public class MyCommandSource : CommandSource
{
protected override ICommand ResolveCommand()
return new MyCommand();
}
public class MyCommand : RowCommandBase
protected override void ExecuteCommand(Row row)
//YourData obj = (YourData)row.Data;
// perform action.
TemplateColumn tc = new TemplateColumn();
tc.Key = "Title";
tc.ItemTemplate = this.GetTemplate();
grid.Columns.Add(tc);
public DataTemplate GetTemplate()
string template = @"<DataTemplate
xmlns=""http://schemas.microsoft.com/client/2007""
xmlns:ig=""http://schemas.infragistics.com/xaml""
xmlns:local=""clr-namespace:XamGridApp_10._3;assembly=XamGridApp_10.3"">
<Button Content=""Click Me"">
<ig:Commanding.Command>
<local:MyCommandSource EventName=""Click"" ></local:MyCommandSource>
</ig:Commanding.Command>
</Button>
</DataTemplate>";
return XamlReader.Load(template) as DataTemplate;
Hope this helps,

Thanks, where should the local namespace and assembly point to?
I figure it shoul point where I put the MyCommandSource, which I placed within the code behind but can't get it to work using my code behind's namespace.
Here's the error I am getting:
The type 'MyCommandSource' was not found because 'clr-namespace:XamGridApp_10._3;assembly=XamGridApp_10.3' is an unknown namespace. [Line: 13 Position: 70]
Solved :-)
I use the Button.Click property when I create the button and set the tag as follows
Tag="{Binding}"
I can catch the value of the column defined by the Key.
Hope this helps anyone looking for a similar solution,
Mike
Hi Everyone,
I am looking to do a similar action. I was able to do it in XAML. I am having problems catching the event handler. Where is it supposed to fire from? Is there a delegate/event I need to set?
Thanks!
OK, thanks Steve
ColumnCommandBase is actually only supported on the HeaderRow level, not the DataRow level, which is why you have to use RowCommandBase.
If you want to use the same command, you can always pass in a flag to the parameter of the commandSource telling it where you are.
Yes that would work, but I would rather use ColumnCommandBase instead of RowCommandBase- is that possible?
