Error during serialization or deserialization using the JSON JavaScriptSerializer.

[Manish]

Hi,

I am using Grid - Virtualization. But when I try to load huge data getting an error "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property." where as also I am using  "OnNeedDataSource"

As per my requirement I need to create Grid columns at run time as don't know how many columns and rows we be there as query output.

I have also used below code in my config file but don't get any success

 <system.web.extensions>
    <scripting>
      <webServices>
        <jsonSerialization maxJsonLength="2147483647" />
      </webServices>
    </scripting>
  </system.web.extensions>

 

Can any body help me out in this.

Thanks

Hello,

The reason for the serialization error is that too much data is serialized at once. Therefore I suggest you try lowering the InitiallyCachedItemsCount on your end (set lower number - 800 for example) and see if maxJsonLength error still appears. Also make sure that paging is enabled.
