Try it without the PMRLog. part of your column name. I'm not sure, but I think that the table name is implicit to the datarow and not necessary here.

Also, I didn't include this in my sample, but you could also do a check for the existance of the datarow object before attempting to use it.

Is the value of ComboBox.Text a string in the debugger?

drPMRLog["Title"] = ComboBox.Text

}
