Adding Dynamic Controls to a DataGrid for use with the built in DataGrid Edit/Update functionality
(VS 2003, .NET 1.1)
I am trying to add dynamic controls to the cells of an Edit Row in a
DataGrid and am having a terrible time.
I cannot for the life of me get the values from the dynamic controls
after the page posts back on the DataGrid UpdateRow event.
When I create a dynamic control (these are almost always
dropdownlists), for example a States dropdownlist, i give the new
DropDownList object an ID: "DYNAMIC_CONTROL_States". I notice when i
view source on the Edit DataGrid webpage the DropDownList's ID in the
HTML is something like "DataGridName__ctl2_ct3_DYNAMIC_CONTROL_States ".
In this case do i have to re-generate the States dropdownlist OnInit
with the ID "DYNAMIC_CONTROL_States" or
Where do i regenrate them? in OnInit()? What does it take to regenerate
DropDownList myStates = new DropDownList().
myStates.ID = DYNAMIC_CONTROL_States;
do i have to add the DropDownList items as well?
is there anything else I have to do to bind the postback value that is
floating around in the ViewState to this control?
Can I see the value without re-generating the control? (ViewState
doesnt have anything in it)
If anyone has _ANY_ insight into adding dynamic controls to DataGrids i
would very much like to hear it. as it stands this is killin me.
Also - has anyone ever seen this working before or suceeded in getting
dynamic controls IN A DATAGRID to postback values? I've read around 50
different articles and have seen anyone say they've suceeded with a
datagrid (they have managed to do it w/ standalone controls).

One last thing - my DataGrid has AutoGenerateColumns = true (so the
DataGrid can display any DataSource)
