How to select a row in kendo grid by data item ID?

You cam mix row itemID and data.uid, I guess.

var grid = $("#Grid").data("kendoGrid");
var dataItem = $("#Grid").data("kendoGrid").dataSource.get(itemID);
var row = $("#Grid").data("kendoGrid").tbody.find("tr[data-uid='" + dataItem.uid + "']");

Going along with what umais has mentioned, the better approach, since there is no built in functionality for this as of yet, would be to iterate through all the records to find the one you need. The function that I built will work even if there are pages of data. The only other way that I can think of doing this would be do do a secondary ajax call; But this works well. Note that i haven't tested it with more than 2000 records.

    var dataGrid = $("#GATIPS").data("kendoGrid").dataSource;
    var numOfRows = dataGrid.total();
    var currentPageSize = dataGrid.pageSize();
    dataGrid.pageSize(numOfRows);
    var dataGridData = dataGrid.data();
    for (var i = 0; i < numOfRows; i++) {
        if (dataGridData[i].uid == e)
            return dataGridData[i];
    }
    dataGrid.pageSize(currentPageSize); // reset the view

e is the UID. However this can be substituted for what ever variable you need just replace the check.
