Hello,
I am trying to hide certain fields on the Add/Edit forms for 1 table based on a dropdown field value on the same form using the template editor. I have not used the template editor before and am not sure where to edit.
I think what I am looking for is a way to set autopostback to true on certain dropdown fields, and in the postback code in on_load I need a way to reference fields specific to this table. When I code something similar to the following into the postback part of the Edit template on_load function:

----------------------------------------------------------

If "##SHORTTABLENAME##" = "table1" Then

'fldtable1field1.Visible = False'

End If

----------------------------------------------------------

I get an error when trying to edit any other table because it does not have a fldtable1field1. Maybe if there is a way to cycle through all ##SHORTFIELDNAME##'s for the current table, that would provide a work around?
Sorry for the broad question. If you need any more specifics let me know.

Thanks in advance for the help,

Paul

Paul,
At first, Template Editor is used for changes applied for all tables.
In this case you can use Table Events- Edit Page-OnLoad in wizard.
This code hide fldCustomerID field when fldEmployeeID is equal 3
Dim fldEmployeeID As System.Web.UI.WebControls.DropDownList = Page.FindControl("fldEmployeeID")

Dim fldCustomerID As System.Web.UI.WebControls.DropDownList = Page.FindControl("fldCustomerID")

If Not IsNothing(fldEmployeeID) AndAlso Not IsNothing(fldEmployeeID) Then

fldEmployeeID.AutoPostBack = True

fldCustomerID.Visible = (fldEmployeeID.SelectedValue <> "3")

End If
