Hello Vaibhav,

Thank you for your patience while I was looking into this matter for you.

This issue is not related to the remote pagination or the external button. The reason for this behavior is because you are reinitializing the grid. What I would suggest you is to initialize the grid only one time and if you need to change its data sorce you can do it through the external button using the dataSource option of igGrid:

function reloadData() {
  var url = "https://mocki.io/v1/f7970ac8-9f6e-4a87-b260-c2f2ed352e8c";
  ds = new $.ig.DataSource({
    type: "remoteUrl",
    dataSource: url,
    schema: oDataSchema,
    responseDataKey: "items",
    responseDataType: "json",
    responseContentType: "application/json; charset=utf-8"
  }).dataBind();
  $("#grid").igGrid("option", "dataSource", ds)
}

Here you can find a small sample demonstrating my suggestion. Please test it on your side and let me know whether you find it helpful.

Looking forward to hearing from you.
