Asp.net - Populate A Dropdown List With Data?
Jun 9, 2009
I have a dropdownlist that I want to populate with a specific value and specific text. I'm not using a datasource but I am manually making a connection and retrieving data in code. How can I populate this dropdownlist? If I read the data with a datareader and increment an array I only get either the value or the text. This is what I have so far, but it is completely wrong:
//connection string etc goes here
Dbcmd2.CommandText = "select dept,deptname from table"
Dim dr As SqlClient.SqlDataReader[code]....
How can I get this to work without having to create a class object for Department? Is there anyway or should I create the class object?

I have the following "contact" data (exampled below) stored in an xml file.I've created a frmContacts windows form and placed a list box control inside it.I'm new to the list box but plan to have the users manage the list by letting them add, delete, and pick from it. For searching there should also be a sort function/button (by last name then first name).If the user deletes from the list the corresponding data in the file will be deleted.If the user picks from or adds to the list, I'd like to find the best way to populate the corresponding data elements on another form (i.e., in their respective text boxes). This will include the ability to edit/save from this other form too.

I am trying to select a dropdown and populate about 10 textboxes with information. The information is in a database. I know one option would be to write a stored procedure and pass the value of the dropdown box to the sp and then use SqlDataReader to readthe values to populate the textboxes. I am new to VB and was wondering if i should attempt this using LINQ?

I would like my gridview to be filtered by the dropdown list I have. It is pulling specific information from the database, so when you choose a value from the dropdown list, it should search through all the records and find only records with the ddl value in them.
The code that I am using in the codebehind for the SelectedIndexChanged is not right though. I get an error message saying 'Value' is not a member of 'Integer'. This is on the line dsCompanyFilter.SelectParameters.Add
It probably has something to do with the gridview not tying to the dropdown list properly, but I am not sure how to fix that code.
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server"><br /><br /><br />
<asp:linkbutton id="btnAll" runat="server" text="ALL" onclick="btnAll_Click" />
