DataSourceRequest is null (Passing too much data?)

[Ricky]

I have a multiselect that I am using to filter the data for a graph. When I select a small number of items from the multiselect everything is working properly. However, when I select 1100 items from the multiselect, the DataSourceRequest is null. Is there a data limit that I have hit? Can I get pass it and actually pass all 1100 item?

I have attached screenshots for context. And here is the .Read call

.Read(read => read.Action("SampleMethodTest", "MyController").Data("MultiSelectFilterValue"))

 

Thanks,

Ricky

Please see attached sample project. Selecting all items will cause a null datasourcerequest. FYI. The data refresh happens after closing the multiselect (i.e. click "select all" -> open and close the multiselect -> fires the event to send data).

Thank you,

Hi Ricky,

Thank you for the provided details. When submitting FormData there is a limit in the number of fields submitted with the form - 1024. The issue occurs as the amount of fields is being exceeded. You can read more about the issue in this StackOverflow thread:

https://stackoverflow.com/questions/38357108/form-submit-resulting-in-invaliddataexception-form-value-count-limit-1024-exce

To resolve it you can try and set the RequestLimitsForm attribute for the count of values per form and configure the MaxModelBindingCollectionSize to increase the size of the collection to bind to a model.

I hope the above helps resolve the issue.
