Question

I am using ItemTemplate & EditTemplate for editing the gridview. (ASP.net + VB).

I click EDIT button then I can check/uncheck those checkbox and amend the textbox value.
When click UPDATE button, it will fire the RowUpdating Event, But I found that when I get the value for update statement, it still get the value before editing, not updated value.

How can I get the latest & updated value ? Thanks.

The following is the VB code:

Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs)

    'Update the values.
    Dim row = Gridview1.Rows(e.RowIndex)

    Dim Col1_SL = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_SL"), CheckBox)
    Dim Col1_VL = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_VL"), CheckBox)
    Dim Col1_ML = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_ML"), CheckBox)
    Dim Col1_PH = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_PH"), CheckBox)
    Dim Col1_APH = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_APH"), CheckBox)
    Dim Col1_TOIL = CType(Gridview1.Rows(e.RowIndex).FindControl("cb1_TOIL"), CheckBox)
    Dim Col1_Others = CType(Gridview1.Rows(e.RowIndex).FindControl("tb1_Others"), TextBox)
    Dim Col1_RosterKey = CType(Gridview1.Rows(e.RowIndex).FindControl("lb1_rosterkey"), Label)

    Using conn As New System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("hris_shiftdutyConnectionString").ConnectionString)
        conn.Open()
        cmd.Connection = conn
        sql = "SET DATEFORMAT dmy;UPDATE troster SET SL='" & Convert.ToInt32(Col1_SL.Checked) & "' where roster_key='" & Col1_RosterKey.Text & "';"
        cmd.CommandText = Sql
        reader = cmd.ExecuteReader()
        conn.Close()
        reader.Close()
    End Using

    'Reset the edit index.
    Gridview1.EditIndex = -1

    'Bind data to the GridView control.
    BindData()
End Sub

The most likely reason will be this.
You are calling BindData() on Page_Load without using !IsPostBack

Protected Sub Page_Load Handles Me.Load
    If Not IsPostBack
        ' Bind Grid only at the first load
        ' Do not load Grid again at Postbacks
        BindData()
    End If
End Sub
