VB.Net - Adding Rows To DataGrid

Good Day Experts!

Not too long ago I had a question posted about adding line numbers to the left-most "gray" column in a DataGrid.  I was able to it working for the DataGrid.  Now, I have copied the DataGrid onto 4 tabs on a TabControl and the line numbers don't work!!!

I have tried and tred to look at the code to make sure I am not missing anything. Her is the code I am using for each DataGrid:

Dim row2 As DataGridViewRow
Dim j As Integer = 0
       For Each row2 In dgrdAcceptedSF.Rows
                dgrdAcceptedSF.Rows(j).HeaderCell.Value = (1 + j).ToString
                 j += 1
       Next

Is there anything that may have been reset in the DataGrid when I copied it that may have been reset causing issues you think?

Thanks,

Can you post the complete code in which you set the line numbers for all the DataGrids?

Thanks.

Dim row As DataGridViewRow
The first block of code for dgrdServiceFailures works! I copied that dataGrid for the 4 other tabs and renamed accordingly.  Then I adjusted the code for each dataGrid...unfortunately those tabs are not working!!!

Dim i As Integer = 0
For Each row In dgrdServiceFailures.Rows
        dgrdServiceFailures.Rows(i).HeaderCell.Value = (1 + i).ToString
        i += 1
Next
dgrdServiceFailures.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToFirstHeader)

Dim row2 As DataGridViewRow
Dim j As Integer = 0
For Each row2 In dgrdAcceptedSF.Rows
         dgrdAcceptedSF.Rows(j).HeaderCell.Value = (1 + j).ToString
         j += 1
Next
dgrdAcceptedSF.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToFirstHeader)

Dim row3 As DataGridViewRow
Dim k As Integer = 0
For Each row3 In dgrdOutOfTimeSF.Rows
        dgrdOutOfTimeSF.Rows(k).HeaderCell.Value = (1 + k).ToString
        k += 1
Next
dgrdOutOfTimeSF.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToFirstHeader)

 Dim row4 As DataGridViewRow
 Dim l As Integer = 0
 For Each row4 In dgrdRejectedSF.Rows
       dgrdRejectedSF.Rows(l).HeaderCell.Value = (1 + l).ToString
       l += 1
Next                    
dgrdRejectedSF.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToFirstHeader)

Dim row5 As DataGridViewRow
Dim m As Integer = 0
For Each row5 In dgrdOutstandingSF.Rows
            dgrdOutstandingSF.Rows(m).HeaderCell.Value = (1 + m).ToString
             m + 1
 Next
dgrdOutstandingSF.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToFirstHeader)

Update:

I just cut and pasted the DataGrid from the second tab to the first tab where the DataGrid is that is getting the row numbers.  I sized them both smaller so I could could see the DateGrid that is getting RowNumbers and the the second DataGrid that is not getting RowNumbers.  

Without changing anything else, the second DataGrid now gets RowNumbers!
Then I cut and pasted the second DataGrid back to the second Tab  and now no RowNumbers!

Very interesting...

Seems like a .Net bug... I think I can't help you.

Good News!

 While I could load the last 4 tabs DataGrids with data while sitting on the first tab, I needed to be on the tab with the DataGrid that I wanted to set the RowNumbers on in order to be able to set the RowNumbers.  

So I use the following before code that sets the RowNumbers:

tabServiceFailure.SelectedIndex = 1

Anyway, it's a strange behaviour.

Congratulations!
