Dont post questions like this. And even you wont get any response if you post like this one. Remove all unnecessary code and post the smallest possible snippet. No one would like to go through this type of lengthy codes.

A dropdown list needs to "have" a few things in order to work with data in a grid or table.

The class is here: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.dropdownlist.aspx

Scroll down towards the bottom and look at the examples for using with databinding.

Otherwise, you need to explain a bit more. Is the dropdown in the table or outside the table? Is it a condition by which the table is set? Is it a dropdown list for a column field value for a record? "not storing on table" is ambiguous.

Solution 1

You need to bind the DropDown if Page.IsPostBack Property[^] is false. So, Page_Load should be like below.

VB

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not IsPostBack
        GetCompanyDetails()
    End If
End Sub
