[Code]...
This is a really basic question. This code currently sets the dropdownlist like I want, but just doesn't return selected month and year. How can I fix this?Note that Main2 sub is for PostBack = True.
i want to create a dropdown list which depend on each other. as example. the 1st dropdown list will let the user to select the type between sector or subsector.
select type: 1) sector
2) subsector
if the user choose sector, the sector value will be appear in the dropdownlist
select sector: 1)technology
2) trading
3) industrial
but if the user choose subsector, the subsector value will be appear in the dropdownlist
select subsector: 1) computer
2) utilities
3) consumer
i try to use the hide code but it turns out to be error. i think because of the data overloading.
this is my code -

this shall populate the dropdownlist data, but in the value i need it to pick up the "ID" field from the stored proc. the stored proc sends two parameters, ID and Name. so i populate name, but how do i populate the id in value like this -

I have a DataGridViewComboBoxColumn, and want to switch the style of the ComboBox control between DropDownList and DropDown (mainly for the text field editing capability). I'd like to do this on a row-by-row basis (at the DataGridViewComboBoxCell level).How would I do that programatically? Or maybe a different way of asking: How do I access the ComboBox control given an object of type DataGridViewComboBoxCell?

I have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table

I'm building a data entry interface and have successfully bound the columns that have reference tables for their data using DropDownList so the user selects from the pre-configured values.
My problem now is that I don't want the first value to be selected by default, I need to force the user to select a value from the list to avoid errors where they didn't pick that field and by default a value was assigned.
Is there a more elegant way of doing this than to add code to include an empty value at the top of the list after I get it from the database and before i pass it to the SelectList constructor in my controller class?

I have a VB.Net Windows app that has a form with a ComboBox. It's dropdown style is set to "DropDownList". When I retrieve a record from the DB, I'm trying to assign a value to the "Text" Property of the ComboBox but it's not taking it. I've tried using the "SelectedText", "SelectedItem" properties and they're not working either.
