GridView - How to get row values without sending callbacks to the server

created 6 years ago

Hello,

This code return only keys for current page.
How I can get all keys in all pages?

[JavaScript]
 function CollectGridData() {
            var columnCount = grid.GetColumnCount();
            var rowCount = grid.GetVisibleRowsOnPage();
            var gridData = [];
            for (var i = 0; i < rowCount; i++) {
                var row = new Object();
                for (var j = 0; j < columnCount; j++) {
                    var columnFieldName = grid.GetColumn(j).fieldName;
                     row[columnFieldName] = grid.batchEditApi.GetCellValue(i, j, false);
                }
                row["KeyField"] = grid.GetRowKey(i);
                gridData.push(row);
            }
            return gridData;
        }

Thanks

    Hello,
    It is possible to access only visible row keys on the client side. Would you please clarify why you need to collect all data in Java Script? Describe the whole scenario in detail. This should help me find an efficient solution.

      Hi,

      When user click save, I want to do some check in client side before saving data.
      This is onclick save:

      JavaScript
      function OnClick(s, e) {  
   var arraydata = CollectGridData();  
   var result = abp.services.app.salaryCalculateService.getMaxMonthCalculate(arraydata);  
    result.done(function (result) {  
        if (result == false) {  
            abp.message.error('Process can not be complete, Because......');  
            return;  
        }  
        else {  
                  do save here  
        }  
    }

      Hello,

      Thank you for the clarification. GridView provides only visible key values. To get values from different pages, the grid sends a callback to the server. As a workaround, you can use the approach from the GridView - How to get row values on the client side without callbacks ticket. The idea is to collect required data, save it to the JSProperties collection and then access it on the client side without sending requests to the server.

      Let me know if you need further assistance.

      Thanks,
      Stanley
