> My Time table has TimeID,Employee,PayPeriod,ChargeCodeID,Hours
> My Chargecode table has ChargecodeID,c_Text
>
> I need an Editable datagrid that will show the
> TimeID,Employee,PayPeriod,C_Text in a label and hours, along with an
> edit linkbutton.
>
> When they click on edit, the edit button turns to Update Cancel
>
> TimeID stays read Only
> Employee stays read only
> PayPeriod stays read only
> C_Text turns into a dropdownlist so they can select the proper
> chargecode via a dropdownlist
> Hours is read/write
>
> What is the best way to do this? I would have thought I add a gridview,
> configure the datasource to the Time Table. Then, I go to the
> ChargecodeID field and ask for it to be converted to a templatefield.
>
> When i open the templatefield there is a label field in there. I delete
> it. I add a dropdownlist. I set its datasource to a source linked to
> the ChargeCode Table. I go to Choose datasource and select c_text as
> the field to display, ChargeCodeID as the value for the dropdown.
>
> Next I go to edit data bindings and for Selectedvalue I set field
> binding to ChargeCodeID

> When I try to open the page I get an error message
