Brian,

If there are too many rows in the grid and the grid has a scroll bar , how to get that particular row in view? system shud automatically scroll the grid to that row...

Thanks!

Swetha.

Hi ljksui,

What version of the grid are you using? There were some old bugs a long time ago where the appearances on a row weren't properly refreshed so a row might maintain the selected or active appearance even after it was no longer selected/active. 

Showing a MessageBox doesn't have any effect on the ActiveRow or the SelectedRows, by the way. Nor would losing focus on the grid. Showing a MessageBox would take the ActiveCell out of edit mode (if it was in edit mode). But that's not really the same thing.

We are on version 15.2.20152.2023

Well, the bug I was referring to was fixed years ago, so that's not it. 

Can you reproduce the issue in a small sample and post it here so we can investigate? 

Thanks for the quick reply.

It seems that if the MessageBox.Show is in the BeforeRowActivate then

 this is where the issue is happening.  It is prompting to save 

(MessageBox.Show) before changing rows and if the user chooses 

yes then it resets the dataview for the grid.  At the point of 

the prompt coming up, it looks as if the current row is no longer 

selected.

Private Sub grdRequisitions_BeforeRowActivate(sender As Object, e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles grdRequisitions.BeforeRowActivate
        Try
 
            Dim dsEmail As New DataSet
            dsEmail.Tables.Add("dsEmailOptions")
            dsEmail.Tables("dsEmailOptions").Columns.Add(New DataColumn("AttachmentPath", GetType(String)))
            dsEmail.Tables("dsEmailOptions").Columns.Add(New DataColumn("DisplayName", GetType(String)))
 
            Dim drNew As DataRow = dsEmail.Tables("dsEmailOptions").NewRow
            drNew.Item("AttachmentPath") = "Path"
            drNew.Item("DisplayName") = "Display"
            dsEmail.Tables(0).Rows.Add(drNew)
 
            drNew = dsEmail.Tables("dsEmailOptions").NewRow
            drNew.Item("AttachmentPath") = "Path2"
            drNew.Item("DisplayName") = "Display2"
            dsEmail.Tables(0).Rows.Add(drNew)
 
            Dim dv As New DataView(dsEmail.Tables(0))
            If Me.DesignMode OrElse Me.FormIsBusy Then Exit Sub
            Dim intanswer As DialogResult

 'The line below is where the grid is seeming to lose focus
            intanswer = MessageBox.Show("save changes before continuing?", SuGlobal.SystemSettings.ApplicationTitle, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question)
            If intanswer = Windows.Forms.DialogResult.Yes Then
                'This would normally be where the data gets refreshed for the grid if the row has changed
            End If
        Catch ex As Exception
            LogError(ex, System.Reflection.MethodInfo.GetCurrentMethod().Name, "")
 
        End Try
    End Sub

I should mention, I moved the MessageBox.Show into the AfterRowActivate event (so it prompts after the new row gets selected) and then it seems to work fine.  As of now this seems to take care of my issue.

Hi, 

In order to investigate this, I'd need a small sample that I can run and debug which demonstrates the problem. This code snippet isn't really enough, because I don't know exactly which tables you are modifying, which row you are editing, what band it's in, etc. 

I tried using your code snippet to duplicate the problem, but I don't see anything like what you describe happening in my test. The code you have here doesn't really even do anything. The DataSet you are creating isn't even used, so the only significant part is the MessageBox. I have attached my sample here so you can see if you get the same results. Or maybe you can modify the sample so that it shows the problem occurring.
