Hello,
We are getting the following error when we are grouping by one column using UltraWebGrid v 11.2 framework 4.0
“Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.”
We set the maxJsonLength property to a large value in the Web.config file and we get the same error.
We have just 295 records. We are using Virtual Scrolling.
.DisplayLayout.LoadOnDemand = Infragistics.WebUI.UltraWebGrid.LoadOnDemand.Xml
.DisplayLayout.XmlLoadOnDemandType = Infragistics.WebUI.UltraWebGrid.XmlLoadOnDemandType.Virtual
When we group by a column we change these properties (I also tried to comment this two lines and I got the same error):
.DisplayLayout.LoadOnDemand = Infragistics.WebUI.UltraWebGrid.LoadOnDemand.NotSet
.DisplayLayout.XmlLoadOnDemandType = Infragistics.WebUI.UltraWebGrid.XmlLoadOnDemandType.Synchronous
How can we solve this problem?
Thanks in advance.
Hello alfmag,
Thank you for posting in the community.
I have tested this scenario, however so far I am unable to replicate the matter using 11.1.20111.2020. Please note that UltraWebGrid has been retired since 11.2. Are you using the versionless assemblies provided for that volume? A small isolated sample would be greatly appreciated and will allow me to research this in detail.
I would suggest that you consider switching to the WebDataGrid/WebHieararchicalDataGrid. More information regarding these controls is available at:http://help.infragistics.com/NetAdvantage/ASPNET/2011.2/CLR4.0/?page=Web_WebDataGrid_WebDataGrid.html
Additional samples demonstrating the features of these grids can be found at: http://samples.infragistics.com/aspnet/
