[CLOSED] 2.3.0 Ext.NET - (Dynamic) GridPanel and Filter

[NaRaine]

After creating a new project yesterday and coping a dynamic GridPanel control (which rendered but no filters) I found the new update broke the code.
Using code peek I could not find "get_TraceWriter()" in the Newtonsoft.Json.JsonSerializerSettings class???

[MissingMethodException: Method not found: 'Newtonsoft.Json.Serialization.ITraceWriter Newtonsoft.Json.JsonSerializerSettings.get_TraceWriter()'.]
Ext.Net.JSON.get_CopyCurrentSettings() +0

This code previously worked BUT the filters DID not get rendered. Hence I created a fresh project FW4.5 to resolve it: using (C#) VS2012 + IIS7.

The code that creates this failure is below. I am creating a GridFilter object and adding to a new GridFilters collection via the addFilter method.
Interestingly; previously when loading the asp page the grid loaded (there were no filters) and when checking the console I found addFilter not defined error (as if the grid filter js script had not been loaded) - there were no load errors on resources. It appeared the method was called before the js fully loaded.

NOTE: DataColumns is based on a DataTable; two properties ColumnName and DataType stored in class object for eneration
Also tried, which failed: gridFilters.AddFilter(new StringFilter { DataIndex = "Test"});

// Iterate the DataColumns object; create GridFilter based on type and add to GridFilter collection

var gridFilters = new GridFilters{ID="GridFilter", Local = true};
            foreach (var gridFilter in DataColumns.Select(s => DataTableToGridFilter(s.DataType, s.ColumnName)))
            {
                gridFilters.AddFilter(gridFilter); // <== Fails when calling this line; adding GridFilter object to Colelction
            }

// Used to generate a Filter object based on DataTable column Type
private static GridFilter DataTableToGridFilter(Type type, String dataIndex)
        {
            if (type == typeof(string)) { return new StringFilter { DataIndex = dataIndex}; }
            if (type == typeof(DateTime))
            {
                var df = new DateFilter { DataIndex = dataIndex };
                df.DatePickerOptions.TodayText = "Today";
                df.DatePickerOptions.MaxDate = DateTime.Now;
                df.MinDate = DateTime.Now.AddMonths(-3);
                return df;
            }
            if (type == typeof(int) || type == typeof(double)) { return new NumericFilter { DataIndex = dataIndex }; }
            if (type == typeof(Boolean)) { return new BooleanFilter { DataIndex = dataIndex }; }
            return new StringFilter { DataIndex = dataIndex };
        }

==================================== Example Code to illustrate =================

.Net 4.0 C#
When this is run it works but does not when the filters are cleared and the recreated (produces the error above)

Uncomment ManuallySetFilters(); to generate the error

<%@ Page Language="C#"%>
<script runat="server">
    
    protected void Page_Load(object sender, EventArgs e)
    {
        if (X.IsAjaxRequest) return;

        var store1 = GridPanel1.GetStore();
        store1.DataSource = GetData();
        store1.DataBind();

        //ManuallySetFilters(); //<== Uncomment to produce the error
    }

    public void ManuallySetFilters()
    {
        GridFilters1.ClearFilters();
        GridFilters1.AddFilter(new StringFilter { DataIndex = "company" });
        GridFilters1.AddFilter(new NumericFilter{ DataIndex = "id" });
    }
    
    public object[] GetData()
    {
        return new object[] {
            new object[] { "3m Co", 1},
            new object[] { "Alcoa Inc",2 },
            new object[] { "Altria Group Inc",3 },
            new object[] { "American Express Company",4 },
            new object[] { "American International Group, Inc.",5 },
            new object[] { "AT&T Inc.",6 },
            new object[] { "Boeing Co.",7 },
            new object[] { "Caterpillar Inc.",8 },
            new object[] { "Citigroup, Inc.",9 }
        };
    }

================= Solution ====================

gridFilters.AddFilter(gridFilter);

produced the error (also previously worked but did not display the filters, the update shows up the issue)

This works and displays the filters correctly

gridFilters.Filters.Add(gridFilter);

Hi @NaRaine,

Strange, I cannot reproduce it.

Though, there is a problem with 2.3.0 which might be related. Here is a workaround.
http://forums.ext.net/showthread.php...l=1#post119136

If the problem persists, could you, please, provide a test case?

As for the AddFilter method. It is supposed to be used with a DirectEvent/DirectMethod only. During Page_Load, please just populate a Filters collection.

The Json.NET exception is also discussed here.

Hence I created a fresh project FW4.5 to resolve it: using (C#) VS2012 + IIS7.

Please clarify what environment were you able to reproduce it with? OS, VS, .NET?

[Daniil]

Could you, please, try the following sample with your old installation which throws the Exception?

We need it to narrow down the problem.

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        JSON.Serialize("test", new JRawValueJsonConverter());
    }
</script>
