Hello,
We have a GridView bound to a BindingLIst of custom business objects. The customer has very strict data validation requirements and doesn't want a new row to be added to the data source until the data is clean, so we have implemented RowValidating and perform validations there for both the 'new' row and existing rows. This works well.
The problem is that if a user decides against adding the row, they can't simply click out of the row, they would either have to finish the row entry and then delete the row, or close out of the form and then return to it. These are not elegant solutions. We wish to provide a Cancel button that will simply discard all changes made to the row, be it a 'new' row or an existing row. How can we accomplish this?
Thanks

I had the controls in the toolbox. Then, attempting to create a test project for RadGridView, opening the property builder and clicking on the Build button on the top, VS2010 crashed. When it restarted, the toolbox no longer has RadControls.
BTW, I was not sure what the Build button was for, I just clicked it to see if my column names would appear in the Grid design view.
Thanks,
Gary Davis

I tried to follow the example for cell formating from your tutorial but this functions is not working
Private Sub radGridView1_CellFormatting(sender As Object, e As Telerik.WinControls.UI.CellFormattingEventArgs)
If e.CellElement.ColumnInfo.HeaderText = "column2" Then
If e.CellElement.Text = "H" Then
e.CellElement.RowInfo.Cells("column1").CellElement.ForeColor = Color.Red
Else
e.CellElement.RowInfo.Cells("column1").CellElement.ForeColor = Color.Black
End If
End If
End Sub
If e.CellElement.ColumnInfo.HeaderText = "column2" Then
If e.CellElement.Text = "H" Then
e.CellElement.RowInfo.Cells("column1").CellElement.ForeColor = Color.Red
Else
e.CellElement.RowInfo.Cells("column1").CellElement.ForeColor = Color.Black
End If
End If
End Sub
e.CellElement.RowInfo.Cells(0) doesn't have any CellElement property !
How I can access another cell from another column in order to change the colour?

Hans

I am trying to add checkboxes to a RadTreeView, but I only want the checkboxes to be on one level of the tree. I have discovered that to do this, I need to turn on checkboxes for the entire tree, and then suppress them where I don't want them. As far as I can tell, using the SetPropertyValueCommand in an Execute would do this, but I haven't been able to find any code showing how this would be done. I need to know how to specify which property is being changed, and how to specify that value.
Otherwise, if there is a better way to accomplish the task, I would appreciate hearing the solution. Any advice would be appreciated.
