grid.ItemContainerGenerator.ContainerFromIndex(index) returns null for the newly added row in code

I was hoping of obtaining the GridViewRow object of the newly added Item (or GridViewRow) by code. The Telerik GridView's ItemSource is bound to Customers ObservableCollection holding Customer object. On the constructor of the window, I populate the Customers collection with 10 items. This shows up fine on the grid. When I click on the button to add 5 more customers, I can see them been added on the grid, however when I try to access the 11th row using grid.ItemContainerGenerator.ContainerFromIndex(10), it returns null.
Is there a different way of obtaining the newly added row's index.

how to make horizontal bar chart with each bar labeled

Hi,

I'd like to make a simple bar chart like the image I've attached. It's really very basic bar chart (not sure Telerik's name for this sort of chart) with a single series. Each of the bars should be labeled with it's value.

Please point me to any examples or snippets that would help me create it. I prefer to do as much of it using MVVM as possible.

Thanks!

problem using readonly vs not readonly slot

Hi,

I create a control using a RadScheduleView and a weekview definition. People using my control pass me a collection of not readonly slot and I want to set the rest of the view as readonly. I want to know if there is a mechanism for doing this in the control.

[Solved] No cell validation UI shown?

http://www.telerik.com/help/wpf/gridview-managing-data-validation.html

Hello, I would like to achieve the red validation pop-out message as shown in the 2nd picture from the link above. All my other codes are working, except for red pop-out message. Is there anything I'm overlooking? Below are my codes:

private void GridCommsEqp_OnCellValidating(object sender, GridViewCellValidatingEventArgs e)

{

switch (e.Cell.Column.UniqueName)

{

case "SSN":

if (e.NewValue.ToString().Length > 30)

{

e.IsValid = false;

e.ErrorMessage = string.Format("{0} must not be longer than 30 characters. " +

"Current length: {1}", e.Cell.Column.Header,

e.NewValue.ToString().Length);

}

break;

case "OfficialDesc":

case "CommonDesc":

.

}

OnRowEditEndedCommandCommandExecuted Not Running

I have a datepicker in a grid column, and when the cell changes, it does not call my grid event "OnRowEditEndedCommandCommandExecuted". How do I make this happen? Thanks.

          <telerik:GridViewDataColumn Header="Date Filled" Width="100" >
                    <telerik:GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadDatePicker SelectedValue="{Binding DateFilled, Mode=TwoWay}"/>
                        </DataTemplate>
                    </telerik:GridViewColumn.CellTemplate>
                </telerik:GridViewDataColumn>
