    I am sending over an array to my MVC Controller and it seems to match the signature. However the array from my data source maps the value as such:


    The model is looking for the following: allocation[0].key=value.

    Is there a way to rewrite the way the array will send out its value to the controller?

    Hello Vincent,

    I am not sure if I understand the exact scenario. If you are using the DataSource to send the data, you can use the parameterMap function to change the way the data is sent. We have a code library which demonstrates how to convert the data when using the Grid DataSource. You can check it on this page.

    As Daniel told you, you should use the parameterMap function of the dataSource:
    dataSource: {
        parameterMap: function(options, action) {
             // your code here
             return options;

    In the options parameter you will have what the dataSource is actually sending to your controller. You should use the action parameter to know when you're reading, creating, ...

    Looking at your requirements looks like your resulting options should be:
    options = [];
    options[0] = {};
    options[0].key = value;

    But be sure to work on another variable before losing the actual data in the options variable.
