    [OPEN] [#26] Grid panel grouping and sorting from code-behind

    Two questions for grouping and sorting in a grid panel:

    1. How do I group a grid panel from code-behind? I can set it in the markup but need to change it at run-time.

    2. How do I sort a grid panel from code-behind?
    I tried to use the SetDefaultSort method but I get a message that Ext.Net.Store does not contain a definition for SetDefaultSort. I also tried setting the store's SortInfo property in the markup but it does not accept it.

    Hi @Manny,

    As I can see there are no server counterparts for the sort and group methods.
    http://docs.sencha.com/ext-js/4-1/#!...re-method-sort
    http://docs.sencha.com/ext-js/4-1/#!...e-method-group

    I will discuss with the colleagues a possibility to add these server methods.

    For now please use:
    Store1.Call("sort", /* arguments */);
Store1.Call("group", /* arguments */);

    That works.

    Thank you very much, Daniil!

    Following up on code-behind for grouping: I am trying to close the grouping via 

    Grouping1.CollapseAll()
    in the page load event. Is this too earlier? Or is this the wrong method?

    I am aware of the client-side solution https://examples2.ext.net/#/GridPane...eous/Grouping/.

    Ultimately, I would like to show the groups collapsed when the page is loaded.

    Yes, you are right, it is too earlier. A GridPanel should be rendered before. So, please use this method (and similar ones) during a DirectEvent or a DirectMethod.

    Please set this option
    StartCollapsed="true"
    for the Grouping feature.

    The Group and Sort methods has been added for the StoreBase class.

    Here is an example of usage the Sort ones.

    Thank you again for the request.

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            this.Store1.DataSource = new object[] 
            { 
                new object[] { "1", "b" },
                new object[] { "3", "c" },
                new object[] { "1", "a" },
                new object[] { "3", "d" },
                new object[] { "2", "f" },
            };
            this.Store1.DataBind();
        }
    }

    protected void Sort1(object sender, DirectEventArgs e)
    {
        this.Store1.Sort("test1");
    }

    protected void Sort2(object sender, DirectEventArgs e)
    {
        this.Store1.Sort("test1", Ext.Net.SortDirection.ASC);
    }

    protected void Sort3(object sender, DirectEventArgs e)
    {
        this.Store1.Sort(new DataSorter() { Property = "test1", Direction = Ext.Net.SortDirection.DESC });
    }

    protected void Sort4(object sender, DirectEventArgs e)
    {
        
        DataSorter[] sorters = new DataSorter[]
        {
            new DataSorter() { Property = "test1", Direction = Ext.Net.SortDirection.DESC },
            new DataSorter() { Property = "test2", Direction = Ext.Net.SortDirection.DESC }
        };

        this.Store1.Sort(sorters);
    }
</script>
