I have a 4 dropdown boxes. The first 2 will populate the 3rd box. The 3rd box populates the 4th dropdown. When I go to submit, I go get the selectedvalue of the 4th dropdown.

I did follow the article TRULLY Understanding ViewState (great article btw) and populating my drop down list is working great. I've even setup a OnSelectedIndexChange event which fires almost as great. The problem I've found is the SelectedIndexChanged event won't fire when selecting the 0th index. It does all other times however. ...

So, I've got an ASP drop down list (this is .net 2.0). I'm binding it with data. Basically, when the page loads and it's not a post back we'll fetch record data, bind all the drop downs, and set them to their appropriate values (strictly speaking we: initialize page with basic set of data from DB, bind drop downs from DB, fetch actual ...

All works fine in all major browsers (Opera, Safari, IE6, IE7, FF3), but not in Chrome. Chrome seems to ignore the SelectedIndexChanged event who had to make the asynch request.

I've long thought (but never practiced for some reason) that a dropdown menu that is dynamically generated and only contains one item, should automatically select that item. This would opposed to the typical approach that I've observed where a blank entry is made at the top and you still have to interact with the menu to make the single ...

I have spent too much time on this problem and am beginning to think that it can't be done in Django. I am pulling a list of pathogen names from a postgres database to a drop down box. The user selects the pathogen, which requires the id to be passed back through django to the database for further retrieval of more data. Please see h...
I've got the setup below. When I click the 'Edit' link on the CommandField, a RowEditing event gets fired, but the row does not allow me to edit; specifically, the DropDownList does not appear. My code seems to conform to all the examples I can find. I'm probably missing something very basic, as I seem to be the only person on the inte...

When the object in question is at a second level, e.g. the object to bind is not in the first level of the returned object Users.ContactDetails.Telephone, as the code below doesn't work: ddl.DataSource = dal.dal_Users.GetAllUsers(); ddl.DataTextField = "Telephon...
