I have a Dataset in my app populated with 10 columns of data. I also have a ComboBox that contains all the names of the columns. What I am trying to achieve is, when a user selects a column name from the ComboBox my app should look at the data in my Dataset from the selected column only and try to find a predefined value. If not found then it should pop up a message box. If all data in the column does match the predefined value then a different message box pops up.
Can someone give me a code example of how to do this as I am having a bit of trouble trying to figure it out.
