    [CLOSED] [2.2 Trunk] Server Side Single Row Selection Problem

    I'm assuming I'm doing it right, but yet, nothing...

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


<script runat="server">
    protected void Page_Load( object sender, EventArgs e ) {
        S.DataSource = new object[] { 
            new { ID = 0, Text = "Test1" } ,
            new { ID = 1, Text = "Test2" } 
        };
        LV.SelectionModel[0].Select( 1 );
    }
</script>

    Hi @michaeld,

    For initial selection, please use:
    <ext:RowSelectionModel runat="server">
    <SelectedRows>
        <ext:SelectedRow RecordID="1" />
    </SelectedRows>
</ext:RowSelectionModel>
    Please use the Select method for selecting during a DirectEvent/DirectMethod.

    Also you need to set up IDProperty="ID" for the Store's Model. Otherwise, the ID ModelField will be a common field, not being a resource for records' ids.

    For completion for others. 

    <ext:RowSelectionModel runat="server">
    <SelectedRows>
        <ext:SelectedRow ID="SelR" runat="server" RowIndex="0" />
    </SelectedRows>
</ext:RowSelectionModel>
    Server side...
    	SelR.SelectedRow.RowIndex=idx;

    There are also the SelectedIndex and SelectRecordID properties.
    <ext:RowSelectionModel runat="server" SelectedIndex="0" />
    <ext:RowSelectionModel runat="server" SelectedRecordID="test7" />
    The SelectedRecordID one supersedes the SelectedIndex one.

    To use SelectedRecordID, don't you need to identify in the model which is the record id field (or primary key or whatnot)?

    If so, please show.

    Yes, it requires to set up a Model's IDproperty (or have a ModelField with "id" Name which is default IDProperty).

    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)
        {
            Store store = this.GridPanel1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { "id1", "test1" },
                new object[] { "id2", "test2" },
                new object[] { "id3", "test3" }
            };
        }
    }
</script>
