    Default Unanswered: Column Header in Grid does not get updated on dropdown selection

    Unanswered: Column Header in Grid does not get updated on dropdown selection


    Hi,


    I was trying to update a Grid Column header based on the values selected from the dropdown (combobox), but it doesn't work for Ext JS 4.1.




    Here is the code that i have tried.
    {
    xtype: 'combo',
    fieldLabel: 'View by:',
    labelWidth: 50,
    store: Category,
    queryMode: 'local',
    displayField: 'CategoryName',
    emptyText: 'Select Category',
    listeners: {
    select: function (field, newValue, oldValue) {
    var store = Ext.getStore('Home.UnreadAlertStore');
    var selectedValue = field.getValue();
    if (selectedValue == 'accession') {
    store.proxy.url = 'Data/value1.json';
     
    var x = Ext.getCmp('AlertGrid');
    x.headerCt.getHeaderAtIndex(columnIndex).setText("New Title");
     
     
    }
    elseif (selectedValue == 'Patient') {
    store.proxy.url = 'Data/value2.json';
    }
    elseif (selectedValue == 'Visit') {
    store.proxy.url = 'Data/value3.json';
    }
    elseif (selectedValue == 'date') {
    store.proxy.url = 'Data/value4.json';
    }
    store.load();
    }
    },
    renderTo: Ext.getBody()
     
    }




    where AlertGrid is the Grid id.


    Thanks in Advance.

    Default


    setText is suppose to update if it's rendered. Have you set a breakpoint and followed the code?
