Hi. The code below is used to add a number of GridViews and Timers to update panels that are then added to a Table. How do I add a tick event handler to each timer that runs certain code in VB.net


    Dim oGridView As New GridView
        oGridView.ID = "xChartGridView" & CStr(oChartGridViewID_Counter)
        Dim oTimer As New Timer
        oTimer.ID = "xTimer" & CStr(oChartGridViewID_Counter)
        oTimer.Interval = "5000"
        Dim dt As DataTable = SQL_Data_Table.GetSQLDataTable(oConnectionString, SQL)
        Dim pvt As New Pivot(dt)
        oGridView.DataSource = pvt.PivotData(RowFields, DataField, oAggregate, ColumnFields)
        oGridView.DataBind()
      up.ContentTemplateContainer.Controls.Add(oGridView)
        up.ContentTemplateContainer.Controls.Add(oTimer)
        T.Rows(0).Cells(oColumn).Controls.Add(up)
        T.Rows(0).Cells(oColumn).Controls.Add(oGridView)

You should be able to add a handler manually after creating the timer

   AddHandler oTimer.Tick, AddressOf oTimer_Tick

You may also need to have the timer created as a private variable in the form, as if its created with a local variable in a subroutine then at the end of the subroutine it will no longer be in scope and hence may not trigger.

eg Private with events oTimer as Timer

Then create the timer and the handler when you need them.

You should also remove the handler when you no longer need it

RemoveHandler oTimer.Tick, AddressOf oTimer_Tick
