Hi all,

 

I am using a computed value from a DataSource and displayed in a Grid column.

I discovered that the way to do this is by putting the function in the schema.model

      schema: {
          model: {
                       id: "ID",
                orderValue: function () {
                          // calculate a double value
                          return orderTotal;
                       },

 

And that I put it in my Gird with this ....

 

{ field: "orderValue()", title: "Order Total Value", width: "10&" },

 But if I put a filter on that column, it seems to be assuming it's a string type.

 I may be missing some config.  Normally I would specify the type in the field def in the DataSource but, as seen above, in this case I am using a function (not a plain field def)

 

Any help would be great.  

 Many thanks.

Chris

Hello Chris,

Setting a function for the schema.model is not supported scenario. In order to achieve the described functionality I would suggest you to use the schema.parse and calculate a field. 

Using this approach it is possible to set the type for the custom field.
