The length of the string exceeds the value set on maxJsonLength property

[Stan]

There is a known problem with maxJsonLength property:

However, this hotfix did not work. Maybe because it is for the MS UpdatePanel?

If so, how can this be resolved? This error comes up when grid tries to pull too many rows.

Hi Stan,

The hotfix you have linked to applies to the UpdatePanel control only. Essentially, the UpdatePanel looks for a key in your <appSettings> and sets the MaxJsonLength property of the internal JavaScriptSerializer object accordingly. The fix, however, is not applicable to any of the RadControls. Microsoft provide the maxJsonLength setting in web.config, but it seems the JavaScriptSerializer class is not affected by this setting.

Given that, we do not have a global means of increasing the MaxJsonLength of the general-purpose JavaScriptSerializer class we use. However, if you open a formal support ticket and send us a test project demonstrating your particular scenario, our support staff may be able to provide a specific solution for your scenario.
