    [CLOSED] SortInfo tag in Store



    Hi Im using a <ext:Store that shows data from an array. this store has the GroupField property set. This generates an error if the SortInfo tag is not used. I noticed that the SortInfo only is able to sort one column, I need to sort several columns.
    The error does not apper if I leave the Field="" blank
    

<ext:Store ID="Store1" runat="server" GroupField="Id" >
<Reader>
<ext:ArrayReader>
<Fields>
    <ext:RecordField Name="Id" />
    <ext:RecordField Name="Name1" />
    <ext:RecordField Name="Name2" />
<Fields>
</ext:ArrayReader>
</Reader>
<SortInfo Field="" Direction="ASC" />
</ext:Store>
    How do I solve this?

    Best regards

    Can you post full code of example?
    Do you have column in GridPanel which reference to Id field? You can add this column and make it Hidden

    I can make a full example if needed later on. But my question is simple.
    1. Is it possible to sort on more than one column?
    <SortInfo Field="Id, Name1, Name2" Direction="ASC" />
    2. Why is the SortInfo tag required when using GroupField="Id" in <ext:Store.

    And to awnser you question, No the "Id" is not a column in the grid. the "Id" is the grouping field.

    I asked about your example because it is strange that with blank sort info you have no js error

    1. Local grouping will only work with local sorting as the 2 are intertwined.
    2. Multiple-column sorting doesn't support.

    Hi
    Here comes an example

    


public partial class Test_Default : System.Web.UI.Page
{
    object[] objArray = new object[] { };


    protected override void OnInit(EventArgs e)


    {


        LoadData();


    }


Protected void LoadData()
{
    ArrayList listData = new ArrayList(objArray);
    listData.Add(new object[] { "Group 1", "A", "B" });
    listData.Add(new object[] { "Group 1", "A", "A" });
    listData.Add(new object[] { "Group 1", "C", "B" });
    listData.Add(new object[] { "Group 1", "C", "A" });
    listData.Add(new object[] { "Group 1", "B", "B" });
    listData.Add(new object[] { "Group 1", "B", "A" });
    listData.Add(new object[] { "Group 2", "A", "A" });


    this.Store1.DataSource = listData;


    this.Store1.DataBind();


}


protected void Store1_RefershData(object sender, StoreRefreshDataEventArgs e)
{
    LoadData();
}


}

    RE: [CLOSED] SortInfo tag in Store

    Hi Mikael,

    I investigated your example. Yes, in your example the blank Field in the SortInfo did a trick. But this work-around can't works in all cases (for example, if you add Proxy to the Store then you get js error related with empty Field in SortInfo). I made changes and now if sort info is absent then GroupField using in sorting logic.

    So you must remove SortInfo with empty Field. Now the Grouping can works without SortInfo

    The code in the SVN
