[Solved] DropDown/Combobox inside MVC Grid - Slow response

[Ashok]

We are using Master / Detail grid. Master grid is "Selectable" and it has Client Side event "OnRowSelect" (based on Telerik Master / Detail) Demo.

We have dropdown list as Template list inside Master. Each time we select row in master grid max record we can have in Detail grid is 20 (no paging). Problem is DropDown list inside master grid has (max 3 value) but is performs very very slow. Also changing row in Master grid loads data in detail grid very slow. We are not going to DB for each row data. We have stored data in Session.

Any idea why DropDown list performance slowly? Why it takes while to load data in Detail Grid? Is there a way to  improve speed?

How do we display (loading.. ) image onRowSelect of master grid?

Hello Tejas,

 
I am not sure where could be the problem before review the implementation. I will ask you to send us a simple test project which reproduces the depicted issue. Thus I will be able to check it locally and advice you further.

As to the second question:
Could you please elaborate more on this? Where do you need to show loading page and when ?

Kind regards,

I will send you sample in a day or two.

Thanks.
