Hello Jack,

The reason responseDataKey: "DataRecords" is not working is because the data returned is an array. That's also the reason for the "Load more data" button not working. You should change your returned data to be wrapped in an object and set responseDataKey: "DataRecords".

Also, your column keys should not contain "DataRecords". Just use the name of the property as a column key.

Last, instead of dataSourceUrl use just dataSource.

Hope this helps,

What exactly do you mean by this? I tried to return the data as a .NET DataTable rather than an array, but the grid throws one of the following exceptions:

Uncaught Error: There was an error parsing the JSON data and applying the defined data schema: The input data doesn't match the schema, the following field couldn't be mapped: ID

- OR -

Uncaught Error: The response type was either not set correctly, or it was not possible to detect it automatically. Please set settings.responseDataType and/or settings.responseContentType.

My DataTable has a column called "DataRecords" whose value is another DataTable with all the correct columns in my grid.

FIXED:

I fixed the problem by simply changing this line in my original post:

recordCountKey: "TotalRowCount"

to

recordCountKey: "0.TotalRowCount"

The "AppendRowsOnDemand" feature now works perfectly. Is this an unusual implementation? I wasn't able to get it working any other way.

Hello Jack,

It's a valid configuration. Your original problem was that the igGrid couldn't find the number of records in the data source, thus it didn't initiate a remote request on "Load more data" click. Setting recordCountKey: "0.TotalRowCount" fixed that.
