This is my Code.

<telerik:RadGridView x:Name="rgvExpenseBased" ShowColumnFooters="True" ShowGroupFooters="True" AutoGenerateColumns="False"
                             CanUserFreezeColumns="False" Grid.Row="1" DragElementAction="None" ShowGroupPanel="False" IsFilteringAllowed="False" >
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Income}" Header="Income" IsReadOnly="True" Width="0.22*" >
                    <telerik:GridViewDataColumn.Footer>
                        <TextBlock Text="Total"/>
                    </telerik:GridViewDataColumn.Footer>
                </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding PrevMonthExpenses}" Header="Previous Month Sep Expenses" IsReadOnly="False" FooterTextAlignment="Right" TextAlignment="Right">
                    <telerik:GridViewDataColumn.Footer>
                        <TextBlock x:Name="tbkTotalPrevMonthPer" Text="50000"/>
                    </telerik:GridViewDataColumn.Footer>
                </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding CurrentMonthExpenses}" Header="Current Month Oct Expenses" IsReadOnly="False" FooterTextAlignment="Right" TextAlignment="Right" >
                    <telerik:GridViewDataColumn.Footer>
                        <TextBlock x:Name="tbkTotalPrevMonthAmt"  Text="50000"/>
                    </telerik:GridViewDataColumn.Footer>
                </telerik:GridViewDataColumn>
                <telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding Email}" Header="Email Alert" IsReadOnly="False" FooterTextAlignment="Center"  TextAlignment="Center"></telerik:GridViewCheckBoxColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

This is how i'm Binding in Code Behind

List<ExpenseBasedData> data = new List<ExpenseBasedData>();
            data.Add(new ExpenseBasedData("Food", "5000", "2500", false));
            data.Add(new ExpenseBasedData("Groceries", "5000", "5000", false));
            data.Add(new ExpenseBasedData("Fuel", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Vehicle maintenance", "1500", "1500", false));
            data.Add(new ExpenseBasedData("Entertainment", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Transportation", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Education", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Books & Magazines", "1000", "1000", false));
            data.Add(new ExpenseBasedData("Clothes / Apparel", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Health & Medicine", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Medical/Health Insurance", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Personal care", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Rent", "3750", "5000", false));
            data.Add(new ExpenseBasedData("Telephone", "1000", "1000", false));
            data.Add(new ExpenseBasedData("Mobile", "1500", "1500", false));
            data.Add(new ExpenseBasedData("Electricity", "2500", "2500", false));
            data.Add(new ExpenseBasedData("Home expenses", "5000", "5000", false));
            data.Add(new ExpenseBasedData("Other Expenses", "5000", "3750", false));

            this.rgvExpenseBased.ItemsSource = data;

Hello Srini,

Unfortunately I was not able to reproduce the issue you described.
Can you verify that all dll's are located in the Bin directory of your project?

Please follow these steps:
1.Create a new Silverlight project.
2.Right click on it and choose the option RadControls For Silverlight --> Convert to Telerik Silverlight Application and add the references you need from the Installation folder as it is shown in the attached picture.
3.Paste the snippet you provided.
4.Build and Run your application and edit any cell.

Try the approach above and let me know if the issue still exists.

Best wishes,
Vanya Pavlova
