JSON Data in Template Column

Hi Peter,

Thanks for contacting Syncfusion Forums.

From your query we understand that you are trying to display array of strings within a grid column using the helper function. But you are getting error "cannot read property filter of null". 

Below is the screenshot of your code:

Screenshot1:

We have validated the reported issue at our end. We are unable to reproduce the reported issue at our end. The reported issue occurs only when the "val" is a  null value. So we suggest you to check if you get any "val" as a null value in "_getVal" method. 

If you get the "val" properly in the "_getVal" method properly as we have shown in the below screenshot, you can render the column template properly

Screenshot2:

You are trying to filter the "ExtraQuantities" by checking whether the UnitDescription value is equal to "Net". If it is equal, then the "Quantity" value will be filtered and set to the column template. But you have used [return p.UnitDescription = property]  instead of p.UnitDescription ==  property]. That is you have just assigned the property to the UnitDescription value instead of checking using "==".
