Ok, I'm REALLY confused. I'm new to C# and i am getting an error that has be
throughly mystified.

CS0121: The call is ambiguous between the following methods or properties:
'DreamweaverCtrls.DataSet.FieldValue(string,
System.Web.UI.WebControls.DataListItem)' and
'DreamweaverCtrls.DataSet.FieldValue(string,
System.Web.UI.WebControls.DataGridItem)'

Has anyone else run across this? I am simply attempting to assign a value to
a drop-down & radio group control upon entering a page.

I can post code if it will be of use.

It would help if you could show the line of code you're having a problem
with.

On a hunch, do you have something like this:

....FieldValue("SomethingHere", null) <-- null is what I'm looking for

If you do, try specifying the type:

....FieldValue("SomethingHere", (DataListItem)null);

or similar, might work...
 
Here are the two lines in question:

<% drpTopicType.SelectedIndex =
drpTopicType.Items.IndexOf(drpTopicType.Items.FindByValue(dsEditNews.FieldValue("NewsType", null) )); %>
&
<% rdoHotTopic.SelectedIndex =
rdoHotTopic.Items.IndexOf(rdoHotTopic.Items.FindByValue(dsEditNews.FieldValue("NewsSticky", null) )); %>

From what you wrote, I assume I should try it like this:

<% drpTopicType.SelectedIndex =
drpTopicType.Items.IndexOf(drpTopicType.Items.FindByValue(dsEditNews.FieldValue("NewsType", (DataListItem)null) )); %>

Well, that prevented the error, but those two fields are now not showing the
incomming value fields, nor are they performing the updated when changed.

Any ideas would be most welcome.
