View 1 RepliesI have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">

View 1 Repliesthere are 2 pages (SummaryGridviewPage.aspx and FormviewPage.aspx) there are insert, item and update templates in the FormviewPage 1st case - there is no problem to insert new record, select and update action in the FormviewPage
2nd case - However, there is problem when i select a record in GV and direct to FormviewPage for edit this code is added in Formviewpage to open the record at readonly mode, no problem
Private Sub RF_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
If Session("RecordID") <> "" Then ' to check New or Old record
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.ChangeMode(FormViewMode.ReadOnly)
End If
End Sub
however, no record if go further from readonly to edit mode then Code is added to the Edit button
Protected Sub BtnEdit_Click(ByVal sender As Object, ByVal e As EventArgs)
FormViewProject.ChangeMode(FormViewMode.Edit)
SqlDataSourceRF.SelectParameters.Item("New_ID").DefaultValue = Session("RecordID")
FormViewProject.DataBind()
End Sub
Now edit problem is solved but when go back to the 1st case (new record, and then edit) Now new record can be inserted, and then show it in readonly mode. but then try to go to edit mode, no record show i think BtnEdit_Click code is conflicted with the built-in "Edit" command Could anyone show me some info how formview retrieve specific record in a proper way?
