Question about datagridview component in vs 2005

I want to know how make an error icon display in the cell of the unbound datagridview.

I've read where this is possible but I can't find code that shows how to make it appear/disappear. I also believw you can set an error tooltip also.

Thanks

Thanks but I've tried that and I don't see any msg. Also, how do you show the error icon?

What is the setting for ShowCellErrors? If it is set to True, when you set Error text, you should get an icon.

ShowCellError is set to true. Here is the code I'm using:

Private Sub grd1_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles grd1.CellValidating

If grd1.IsCurrentCellDirty Then
grd1.ShowCellErrors = True

Dim cell As DataGridViewCell
cell = grd1(e.ColumnIndex, e.RowIndex)
If IsNumeric(cell.Value) Then
Exit Sub
End If
cell.ErrorText = "Invalid Data"

End If

End Sub

What are the cell bounds? What are the cell icon bounds?

Hey,

That's why I'm asking the question. I don't know how you do this!

Bob Learned

How wide is the column?

I see another problem:

If you are checking grd1.IsCurrentCellDirty, then the data hasn't been saved to the grid yet, and so you can't query the cell for the value with cell.Value.

You need to query cell.EditedFormattedValue instead of cell.Value.

I guess it would be beneficial to maybe see this function coded correctly. The cells are wide enough to display 5 digits but only 4 is allowed. I'm unsure as to how the error icon is displayed in the cell, if you can position it, or how much wider the cell needs to be to accomadate it.

so does this allow for room in the cell for the error icon?

Bob Learned

Yes, since you were never reaching the code that was setting ErrorText, since you were checking cell.Value. With that code that I showed you, you be able to cell the error icon now.
