Hello all,
Using RadGrid version 2011.3.1305.40 I have a gridcalculatedfield that works until I want a total at the footer.

This is my field:
<telerik:GridCalculatedColumn 
                            DataFields="oneAmt,twoAmt,threeAmt" 
                            Expression="{0}-{1}-{2}"
                            UniqueName="netAmt" 
                            AllowFiltering="False" 
                            AllowSorting="False"
                            DataFormatString="{0:c}" 
                            Groupable="False"
                            HeaderText="Net Amount" 
                            Reorderable="False" 
                            ShowSortIcon="False" Aggregate="Sum" DataType="System.Decimal" 
                            FooterAggregateFormatString="{0:c}">
                            <FooterStyle HorizontalAlign="Right" />
                            <HeaderStyle HorizontalAlign="Right" />
                            <ItemStyle HorizontalAlign="Right" />
</telerik:GridCalculatedColumn>

The error I get when I run this is:
Inner Exception Type: System.Reflection.TargetInvocationException
Inner Exception: Exception has been thrown by the target of an invocation.

Hi All --

I have a templated column in my grid with a checkbox in each row.  Is there an easy way, client-side, to loop through and check/uncheck all of them?

This is not the built in checkbox column for selecting rows, but a separate column altogether.

Thanks!

Hi,

How can I prevent the user from changing the slider value? One way to do this is by disabling the slider, but the look and feel isn't good.

Thanks

Sir,

As hierarchical radgrid not suppor the databind method but is there any support how can we bind the data to hierarchical radgrid 
through webservice through client side.

Hi,

Radgrid details:
- I have setup only one column in the grid as a text box in item template. I need to implement something like excel, where user can enter/edit data in this cell, and press enter or down key to move to the cell on the row below.
- I have registered double click event on the row to redirect the user to a different page.

Can you please help me out with the problems below:
- On pressing enter in the cell (text box), a refresh / rebind happens. How can I avoid it? I tried putting in a default invisible button as well, but even that didn't work.
- On Double click of the cell (text box), the redirect happens. How can I avoid it? I tried having an "ondblclick" return false, but it didn't work.

Regards,
Saumil

Hi All,

Just getting into creating custom skins, and have completed the combobox. All is working well other than the fact the check boxes still use the old skin sprites. How do i change the skin for the check boxes in the combo box? Is there a common gif that needs changing as there is seemingly no reference to anything the ComboBox_{skinname}.css file, and there are no check box sprites in the copied skin folder.

Any help would be appreciated.

Thanks
