DropDownList Problem

[Ring]

Hi community, I'm having a problem,

I dinamically create a table wich contains the results of a search, in each row of that table I create a dropdownlist called DD_ACTIONS and add this AddHandler DD_ACTIONS.SelectedIndexChanged, AddressOf DD_ACTIONS_Selected_Index_Change[/i] in order to execute the code when the Selected Index Change, so the problem is that it works but only once because on the postback event of the page the table containing the dropdownlist is created again so the values of the dropdownlists are always the same, any suggestions???

Regards...

Dear Ring,

try to use the boolean function IsPostBack Page level to customize your query.

If I miss somthing please post your filling code so we can modifay it togather.

Thanks mdaRock

when I create the table there is a cell where I create each dropdownlist, the code for add this cell is

'DOCUMENT ACTIONS
Dim TC_ACTION_ITEM As New TableCell
TC_ACTION_ITEM.HorizontalAlign = HorizontalAlign.Right
Dim DD_ACTIONS As New DropDownList
AddHandler DD_ACTIONS.SelectedIndexChanged, AddressOf DD_ACTIONS_Selected_Index_Change
DD_ACTIONS.ID = myReader("DocumentID")
DD_ACTIONS.DataSource = SqlDataSource1
DD_ACTIONS.DataTextField = "FunctionName"
DD_ACTIONS.DataValueField = "FunctionID"

'CREATE "CHOOSE ACTION" ITEM
Dim liCA As New ListItem
liCA.Text = "Choose Action"
liCA.Value = "-1"

'CREATE "OPEN DOCUMENT ACTION" ITEM
Dim liOD As New ListItem
liOD.Text = "Open Document"
liOD.Value = "-2"

DD_ACTIONS.Items.Add(liCA)
DD_ACTIONS.Items.Add(liOD)
DD_ACTIONS.AppendDataBoundItems = True
DD_ACTIONS.AutoPostBack = True
DD_ACTIONS.EnableViewState = True
DD_ACTIONS.DataBind()
TC_ACTION_ITEM.Controls.Add(DD_ACTIONS)
TR2.Cells.Add(TC_ACTION_ITEM)

then on the DD_ACTIONS_Selected_Index_Change Sub what I'm doing is this:

Select Case sender.SelectedValue
Case "-1"
'CHOOSE ACTION: DO NOTHING
Case "-2"
'CHECK(DATABASE)
Case Else
"DO SOMETHING
End Select

but the problem is that on the postback the cell that contains the dropdownlists needs to be created, an the postback ocurr before the DD_ACTIONS_Selected_Index_Change Sub so each time you enter the Sub the selectedValue is the same it never change...
