Kendo UI Grid Server Detail Template Demo Problem

[Anton]

Hi,
When I run the Kendo UI grid server detail template demo downloaded with my trial edition I've noticed a problem. If you open up the detail template for the second customer (Andrew Fuller) then select the 'Go to next page' button on the orders grid that template is closed and the template for the first customer (Nancy Davolio) is opened instead. This doesn't happen for the client detail template demo but I want to use my grid as per the server detail template demo. Is there a work around for this problem?
Regards,
Mark

Hello Mark,

Indeed this how the demo is designed. On every page command, rebind is executed and the following action expands the first item in the page.

.RowAction(row =>
    {
        if (row.Index == 0)
        {
            row.DetailRow.Expanded = true;
        }
    })

Thanks. If I comment out the RowAction and repeat my steps the grid is redisplayed with no detail templates open. This may be no surprise but how do I alter the client code so that the detail template is still open for the second customer as you page that that customer's orders?

Hello Mark,

You can see how to persist expanded item in the Server Hierarchy demo, namely:

.RowAction(row =>
{
 var requestKeys = Request.QueryString.Keys.Cast<string>();
 var expanded = requestKeys.Any(key => key.StartsWith("Orders_" + row.DataItem.EmployeeID) ||
   key.StartsWith("OrderDetails_" + row.DataItem.EmployeeID));
 row.DetailRow.Expanded = expanded;
})
