responsecode from store callback not coming

Hello Folks,

The callback method does not have the server response passes as object. There are many ways to load the data into the store and not all of them have a server response.

For this we have to override the proxy processResponse function in the store withe operation object contains serverResponse.

    Ext.define('', {
            override: '',
            processResponse: function (success, operation, request, response, callback, scope) {
               operation.serverResponse = response;

        callback: function(records, operation, success, response) {
        if(success == false){
              var response = operation.serverResponse;            
            var responseText = Ext.decode(response.responseText);
if(responseText.status == 404){
 Ext.Msg.alert('Service Unavailable');

Difference between renderer and convert

In Extjs everyone has small confusion what is the Difference between renderer and convert.

renderer: renderer is an "Interceptor" method which can be used to transform the data like value, appearence..before it rendered to the browser.

renderer: function (value, metaData, record, rowIndex, colIndex, store, view) {
    // style the cell using the dataIndex of the column
    var headerCt = this.getHeaderContainer(),
        column = headerCt.getHeaderAtIndex(colIndex);

    metaData.tdCls = 'app-' + column.dataIndex;
    return value;

It will returns the HTML string.

convert: convert is a function this converts the value provided by the reader into an object that will be stored into the Model.
This function access the rows information inside the store, based on this we can modify the data.

.Net sorting list with special characters

Sorting using c# .Net  doesn't use ASCII while sorting, It uses Unicode. When we perform a string sort, .Net by default uses the current culture.

Sorting a list in c# with special characters like "-", "/"

1.  Here is the Sample Data before sorting.

We can't get sort String having the special characters, Now we can do with RegExpression.

using System.Text.RegularExpressions;


response.Result = response.Result.OrderBy(f => Regex.Replace(f.Name.TrimStart().TrimEnd(), "[^a-zA-Z0-9_]+", " ")).ToList();


   response.Result = response.Result.OrderByDescending(f => Regex.Replace(f.Name.TrimStart().TrimEnd(), "[^a-zA-Z0-9_]+", " ")).ToList();
