I just tried your control on my ASP.NET MVC application is it works flawlessly! Great job! When I’m done with the site you’ll be added to the contributors. (By the way, it’s not being used on MVC Starter Kits) Thanks.

@Ezequiel – Sorry to hear that you’re having problems with the control.

I tried putting the control in a formview, and couldn’t reproduce the error you mention.

Just to let you know, I created an object data source, which exposed several email addresses. This object data source was the data source for the form view control, and this form view control had a Gravatar control in it. I was able to page through the records without an issue.

Would you mind going into a little more detail?

I like this control. The source code is very clean and easily adaptable. I modified it only slightly to support ASP.NET 1.1 (my web site has been running on that for years) and am now using it on my Blog.

Thanks for making this available.

Thanks for your comment Kenneth. I’ll make the changes to my posted source when I get the chance, and credit you with the change.

First, thanks for posting your great source!

Second, I found that when this control was in a aspListView and the listview was posted back, the Email property wasn’t getting set because it was databound.

I added the following code to the Gravatar class and now the email property is saved in viewstate :):

protected override object SaveViewState()
{
return new Pair(base.SaveViewState(), _email );
}

protected override void LoadViewState(object savedState)
{
if (savedState != null)
{
Pair state = savedState as System.Web.UI.Pair;
if(state != null)
{
base.LoadViewState(state.First);
_email = (string)state.Second;
}
}
}
