[RESOLVED] [2005] ToolTip on Gridview

[danasegarane]

Hi all,
I have Datagridview with some columns. All the Columns are TextboxColumn with Readonly=True.The Data in the rows contains details of id,startdate and enddate. When I move the mouse over the id it not displaying any tooptip.But when I move over any cell which shows date(Textboxcolumn), it is showing tooptip.Please see the attachment.Is it bug on Datagridview ?

No it's not a bug. The grid only shows that tip if the cell isn't displaying all the data. As you can see, the values in the StartTime and EndTime columns are too long so an ellipsis is used to indicate that there's more data. Only then will the tip be displayed, specifically so you can see the hidden data. Why would you need a tip if all the data is already visible in the cell?

I think this has to be noted. Thanks for the point

No!!!!!!!!!!!!!!!!1
DatagridView cell can show tooltip for the data which is being fully visible.

there is code for that

'Take Tooltip1 if needed
    Private Sub DataGridView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseMove
        Dim pt As Drawing.Point
        pt.X = e.X
        pt.Y = e.Y

        Dim hti As DataGridView.HitTestInfo
        hti = DataGridView1.HitTest(e.X, e.Y)
        If hti.Type = DataGridViewHitTestType.Cell Then
            DataGridView1.Rows(hti.RowIndex).Cells(hti.ColumnIndex).ToolTipText = DataGridView1.Rows(hti.RowIndex).Cells(hti.ColumnIndex).Value
        End If

    End Sub
