In row validating event I check some values and if is a wrong value I wrote
e.Row.ErrorText = string.empty
if my condition .is not OK
e.Row.ErrorText = "BlaBla"
e.Cancel = true
end if
All very nice but after i validate and this new row is inserted in datagrid , I still have the red error sign besides of the "Click here to add new row" .
What I'm doing wrong ?

Hello Mihai,
Thank you for contacting us.
I tried to reproduce the problem on my side but without success. Therefore I would ask you to prepare a very simple project that demonstrates the issue so that I can debug it and further help you.
I am looking forward to your reply.
Kind regards,
Georgi

Hi !
I don't know how to attach a project.
But Anyway !
In a new winform project drag a rad gridview on the form. Don't change anything in properties .
Add this code :
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadData()
End Sub
Private Sub LoadData()
Dim dt As New DataTable("Test")
Dim dc As New DataColumn("Col1")
dc.DataType = System.Type.GetType("System.Int32")
dt.Columns.Add(dc)
dc = New DataColumn("Col2")
dc.DataType = System.Type.GetType("System.String")
dt.Columns.Add(dc)
Dim dr As DataRow = dt.NewRow()
dr("Col1") = 1
dr("Col2") = "String1"
dt.Rows.Add(dr)
dr = dt.NewRow()
dr("Col1") = 2
dr("Col2") = "String2"
dt.Rows.Add(dr)
RadGridView1.DataSource = dt
End Sub
Private Sub RadGridView1_RowValidating(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.RowValidatingEventArgs) Handles RadGridView1.RowValidating
Dim objRow As GridViewRowInfo = e.Row
If objRow Is Nothing Then
Return
End If
Dim drView As DataRowView = objRow.DataBoundItem
If drView Is Nothing Then
Return
End If
e.Row.ErrorText = String.Empty
If drView.Item("Col2") Is DBNull.Value OrElse drView.Item("Col2").ToString().Trim = String.Empty Then
e.Row.ErrorText = "Col2 Field must be filled in !"
e.Cancel = True
Return
End If
Return
End Sub
Add a new row.
Add a numeric value in column 1. Left click with the mouse on another row.Come back on the new row and press Enter. This row is at the end of the grid and there is still a red error mark on the line with "Click here to Add new row ".
If I put e.cancel = true It should cancel adding the new row to the table, isn't it ? Because in this case it still adds this new row to the grid even I put e.Cancel = true.
Regards,
Mihai

Hi Mihai Velicu,
Thank you for the additional details.
Despite the fact that GridViewNewRowInfo has an ErrorText property (it comes from inheritance), it cannot be used in the same way as with GridViewDataRowInfo. That is because, the "add new row" has some specifics. plus the validation process is different. That means that we still do not support error provider scenarios for adding new row elements, and there is no easy way to show the data error icon and text. We are aware about this limitation and we will improve this feature for some of the next releases.
As to attaching your projects, you need to use the support ticketing system. Attaching code and assemblies in the Forums is forbidden, although you can paste code, if needed.
Let me know if you have any other questions.
