Hello

How is it possible to access the a row/cell of a child grid?

E. g. I have a grid with 20 rows and I want to access from the 10th row the 3rd row of the second nested/child grid.

8th Row
- Grid 1 to 3
9th Row
- Grid 1 to 3
10th Row
- Grid 1
- Grid 2
     Row 1
     Row 2
     Row 3
- Grid 3

Thank you in advance.

[Solved] Dynamically bestfit columns as user scrolls a grid

I would like to bestfit all the columns dynamically as user scrolls a grid vertically.
I don't know if this is at all possible, since there seems no event that is called in grid when user scrolls it vertically.

I am using Q1 2008 SP1 radgridview.

Thanks
Sunil

Validation with business rules in dataset

I've got a simple RadGridView bound to a DataTable (through a BindingSource); standard and easy way to put a gridview on a form dragging it from datasources box.
I've implemented my business rule validation in the datatable, as below:

Private Sub OperazioniDataTable_ColumnChanging(ByVal sender As System.Object, ByVal e As System.Data.DataColumnChangeEventArgs) Handles Me.ColumnChanging

Debug.Print("ColumnChanging: column=" & e.Column.ColumnName)

If (e.Column.ColumnName = Me.impovalColumn.ColumnName) Then

If CType(e.ProposedValue, Decimal) = 0 Then

e.Row.SetColumnError(e.Column, "Inserire un importo diverso da zero")

Else

e.Row.SetColumnError(e.Column, "")

End If

End Sub

When I edit the [impoval] cell and enter 0, moving to another cell/row raises the ColumnChanging event, but no feedback at all on the grid.
Another issue: if I press [Escape] key in the cell, the value is not restored to the old one.
In the standard MS grid I get feedback and restore behaviour.
I would like to know the best practices to enforce data validation (on single cells and on row, moving away from a cell/row and/or trying to close a form, etc.), possibly avoiding to put rules in the gridview events, in order to keep all the business rules validation code in the data transfer objects.
Please don't suggest to create separate business objects, as I want to avoid this coding overhead.
TIA

[Solved] Deployment question

I have the need to deploy multiple applications that use the rad controls. In general, I need to deploy the 2 DLL's telerikcommon and telerikwincontrols. Rather than have them deploy with each application, I want to have a seperate deployment of these 2 dlls to the gnc and then have them marked are pr-requesites for the other application deployments. I am not sure how this can be accomplished. Any help you can provide in this matter will be greatly appreciated.
