Runing code when form is loading does not work

Hi there

I want to be able to put a link label onto a datagrid.

The following works on a loaded form:

        Dim ColumnToChange As Integer = 2
        Dim CurrentValue As String

        For i As Integer = 0 To DataGridView1.Rows.Count - 1
            CurrentValue = DataGridView1(ColumnToChange, i).Value
            DataGridView1(ColumnToChange, i) = New DataGridViewLinkCell
            DataGridView1(ColumnToChange, i).Value = CurrentValue
        Next

But when it is run on the on_load event or the activated event it runs through the code - but does not display the link label on the grid.

How can I get around this?

many thanks in advance

Hi  DavidGreenfield, put the code in your Form1_Activated event:

    Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
        Dim ColumnToChange As Integer = 2
        Dim CurrentValue As String

        For i As Integer = 0 To DataGridView1.Rows.Count - 1
            CurrentValue = DataGridView1(ColumnToChange, i).Value
            DataGridView1(ColumnToChange, i) = New DataGridViewLinkCell
            DataGridView1(ColumnToChange, i).Value = CurrentValue
        Next
    End Sub

I did try the code in the activated event and it still doesn't work.  If i run it from a button click it works though.

For most datagridviews I am showing it doesn't matter - but this one is a static grid that the user can immediately view when loading the screen

thanks for your help

Hi there manch

I did put it in the initializecomponent event and that didn't work either, I can't seem to tell if it is being run or not though

Should I be putting more than just the link label code in there?

This must mean that the data is still being loaded after these events ?

Data takes about 5 seconds to load so possible.

Is there anything I can do to hold off adding a link label until the datagrid has finished loading?

I have managed to get around this,

Basically by calling the code as below works:

Public Sub test(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load

I was calling it in (and lots of combinations based on):

Private Sub Form(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I hope this will help someone else out too!
