DataGrid DropDown Template Column

[Guest]

I'm new to Web development so I'm doing some bootstrapping and would really
appreciate any help. Been grappling with this for days and am utterly
confused by all the information on the web. I have a DataGrid with customer
information. The last column is a dropdown template column that allows our
reps to assign an attribute to the account i.e. small, medium, large or
something like that. Here's where I'm stuck 1) I can't get the drop down list
to populate 2) Once populated, I'm not really sure how to update the sql
table where the customer information is stored.

The sql table that I'm updating is called AdHocAccountTypes and has two int
fields: AccountID, AccountTypeID

The sql table that should poplulate the dropdown is called
AdHocReaAccountTypes and has two fields:
AccountTypeID, int
AccountTypeDesc, VarChar(16)

Here's my HTML:

<Columns>
<asp:BoundColumn DataField="AccountID" SortExpression="AccountID"
HeaderText="ACCOUNT #"></asp:BoundColumn>
<asp:BoundColumn DataField="ACCDESC" SortExpression="ACCDESC"
HeaderText="ACCOUNT NAME"></asp:BoundColumn>
<asp:BoundColumn DataField="CITY" SortExpression="CITY"
HeaderText="CITY"></asp:BoundColumn>
<asp:BoundColumn DataField="STATE" SortExpression="STATE"
HeaderText="ST"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="CHOOSE ACCOUNT TYPE">
<ItemTemplate>
<aspropDownList id=ddlAccountType1 runat="server"
DataValueField="AccountTypeID" DataTextField="AccountTypeDesc"
DataSource="<%# FillddlAccountType %>">
</aspropDownList>
</ItemTemplate>
<EditItemTemplate>
<aspropDownList id=ddlAccountType2 runat="server"
DataValueField="AccountTypeID" DataTextField="AccountTypeDesc"
DataSource="<%# FillddlAccountType %>">
</aspropDownList>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:EditCommandColumn ButtonType="LinkButton" UpdateText="Update"
CancelText="Cancel" EditText="Edit"></asp:EditCommandColumn>
</Columns>

Here's my code behind:

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

Dim strTerritory_ID As String = ddlTerritory.SelectedValue
BindData(strTerritory_ID)
End Sub

Private Sub BindData(ByVal _ID As String)
Dim _SqlAccounts As String = "Select AccountID, AccountTypeID,
ACCDESC, CITY, STATE from ACCLIST INNER JOIN AdHocAccountTypes ON
ACCLIST.ACCID = AdHocAccountTypes.AccountID AND TERID = " & _ID & " ORDER BY

It took the better part of a weekend but I was able to somehow piece this
together. Thanks.
