I have a combobox in a form, I want to fill it with names I have stored in a database. I know I have to use the fill command, but I am not sure what code I need to use. I imagine I need to place this code in the form load event, where I wrote my code to connect to the database. Do I need to create a sql fill command, select Names From Users, then execute that command in the combo box object.

View 6 RepliesI am designing a form to Enter new City Name list where i accept following fields
CityName, District, State, Country, Pin.
because a State names and Country names can be retrived from earlier entries, i want to allow user to select desired name from a list in combo box or a list in Auto Complete Custom Source for text box, to do this i have added a Table Adapter to underlying DataSet having Query "SELECT DISTICT STATE FROM CITY ORDER BY STATE".
Now, how do i use this Table Adapter to fill the ComboBox List without binding
And also Custom Source List for TextBox.
I dont think I am writing the values to the object. Not sure if this is the best way to do this with multiple values.Public Function ListDMR() As DMRDataLists

View 1 RepliesVB 2008 .NET 3.5. I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment.
My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc.
I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment."
In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use.
I have tried a few ideas, but none of them work properly.
Was updating a project and all of a sudden the auto-filling of a WebBrowserControl's Dropdownbox stopped working. Here is the HTML of the Input box:
[Code]....
I think it is the "onkeyup" thing that isn't getting fired properly so the dropdown list isn't updating itself... it was working fine before, and now, with no changes, it just stopped working. can someone take a look at my code and see if they spot anything? EDIT: attached an image of the dropdown box in question. as I type, it does the lookup. (using the onkeyup event). I am setting the value of the dropdown to the five digit code at run-time, trying to trigger the onkeyup event to get it to get the full line, but it won't work.

I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:
System.IO.Path.GetExtension()
System.IO.Path.GetFileName()
System.IO.Path.GetFileNameWithoutExtension()
