I have a radgrid control (with detail tables) on an aspx page . I have button column on the parent and  the child(detail

tables) as well.

Based on some criteria I have to disable/enable the button column on parent and/or the child.
what is the best way to do it?

To explain further, the parent display the order  and when click on the order it shows the order items for the order.
the button column is to duplicate an order. the button on the parent duplicates the whole order. the button on the child

(order items) duplicates an order with that particular order item.
Please advise the best solution,
Thanks

Hi,

I have one situation where i want to find the header of Grid and apply the custom css. In grid I have following column and want to get the header of this column in code
            <ExpandCollapseColumn Visible="True">
            </ExpandCollapseColumn>
                <telerik:GridTemplateColumn UniqueName="AssociateColumn">
                    <ItemTemplate>
                        <asp:HyperLink ID="Lnktest" runat="server" Text="test"></asp:HyperLink>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

I have follwoing code to get the header and i am able to get that for other columns but not for this above column.

if (e.Item is GridHeaderItem)
            {
                GridHeaderItem item = (GridHeaderItem)e.Item;
                foreach (GridColumn col in GridAttorney.MasterTableView.Columns)
                {
                    if (col is GridEditCommandColumn || col is GridButtonColumn)
                    {
                        item[col.UniqueName].CssClass = "gridsBlankheadercolumn";
                    }
                }
            }

Can anyone tell me How to get this Column header in this above code ? Also please see the attached screenshot for better understanding.

Thanks,

hi,
i'm wanting to use the multiple file upload feature, but instead of the uploadprogress showing above the "input" button. I'd like to move it inside a listbox item row.

ideally if i added multiple files, i'd like to see each progress for each file show up in its own listbox row.

is this possible, and if so can someone give me some guidance?

thanks

Hi,
I am facing issues while converting my application from classic RadControl to ASP.NET AJAX radcontrol.
My requirement is that on row click of one grid (dgProductGroup in the below code snippet, I need to update dgProduct).
Earliler I was using the below code in my ASPX page:



And this was the javascript part.


With the new Rad Ajax, I either get error that object does not support the method (in javascript EnableGrid function) or the grid fails to load and I only see the loading image.
Can you please help me in this upgrade.

Thanks,
Ripunjay

Hi All,
When I display the advanced form in my app (not Modal)...the RadScheduler "breaks up" the form into sections.
See attached image.

Anyone have any idea why this is happening?

I am following the resource example (with changes) and I am getting an error (Microsoft JScript runtime error: Object doesn't support this property or method) when I am in the following function - it is bombing on slot.get_resource();

 

function isRoomOccupied(scheduler, start, end, slot, appointment)

{

//get the "Room" resource associated with the time slot

var currentRoom = slot.get_resource();

//get all appointments for this "room" in the specified period

var appointmentsForThisRoom = getAppointmentsInRangeByResource(scheduler, start, end, currentRoom, appointment);

//if the list of appointments is not empty there are other appointments in this slot

return appointmentsForThisRoom.get_count() > 0;

}

I am not sure what I am doing wrong. Thanks.
