I forgot my read action and i think the problem is when i use server pagination with a read action with addionaldata
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public ActionResult Read([DataSourceRequest]DataSourceRequest request, int companyId)
{
List<TravelPreferenceVM> lstVM = new List<TravelPreferenceVM>();
if (companyId > 0)
lstVM = travelPreferenceService.GetByCompany(companyId);
return Json(lstVM.ToDataSourceResult(request));
}
Thank you for providing the code.
After inspecting it, it looks good and it should work as expected. Still, in order to determine what may be causing the issue, please share with us what is happening when the Excel export button is clicked? For example, is there any JavaScript error in the console, or if the ExcelExport action is hit in the controller.
Also, providing a fully runnable example will be very helpful as it will allow us to inspect the application and provide a suggestion best suited for it.

Hello Stephan,
Thank you for your reply but i forgot to post the solution. The problem was from the length of JSON sended to the grid for serialisation, I delete the field from my object (ViewModel) and it works. But i have a question, How we handle long Json-String?
Thank you for the clarification.
If the JSON length is too large, I can assume that there is an error on the server.
I can suggest checking the following questions on StackOverflow as they demonstrate how to change the JSON max length and provide more information on the different JSON length limitations that can be hit:
https://stackoverflow.com/questions/1151987/can-i-set-an-unlimited-length-for-maxjsonlength-in-web-config/1151993#1151993

Hi Rajiv,
As far as I understand the issue you are facing is related to the Kendo React, thus I would suggest submitting your question in the dedicated forum:

If this is not the case and you have questions related to the Kendo UI for jQuery components, please let us know.
