    [CLOSED] Select a Row from GridPanel in DirectMethod

    Hi,
    so, after upgrading my user to premium, this is my first question ;-)

    Is is possible like the commit to select a row / or multiple rows after new binding
    from code behind.

    Something like this:

    [DirectMethod(Namespace = "CompanyX")]
public void AfterEdit(String Name)
{
       Store store = this.GPanel.GetStore();

       data.Add(Name);
       ....
       data.Add(Name+Name);

       data.Sort(delegate(SampleClass p1, SampleClass p2) { return p1.name.CompareTo(p2.name); });
       store.DataSource = data;
       store.DataBind();


        this.GPanel.Store.Primary.CommitChanges();

        // SELECT THE NEW ADDED ROWS

}

    Hi,

    Welcome to the Premium support:)

    There is big server API to select rows. I used the SelectRange() method. Intellisense will show you others.

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

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

<script runat="server">
    private List<object> MyData = new List<object>()
    {
        new { test="test1" },
        new { test="test2" },
        new { test="test3" }
    };

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.GridPanel1.GetStore();
            store.DataSource = MyData;
            store.DataBind();
            this.Session["MyData"] = MyData;
        }
    }

    [DirectMethod]
    public void DataBindAndSelect()
    {
        var myData = this.Session["MyData"] as List<object>;

        myData.Add(new { test = "test" + Guid.NewGuid().ToString() });
        myData.Add(new { test = "test" + Guid.NewGuid().ToString() });
        
        Store store = this.GridPanel1.GetStore();
        store.DataSource = myData;
        store.DataBind();
        this.Session["MyData"] = myData;

        int count = myData.Count;
        var selModel = this.GridPanel1.GetSelectionModel() as RowSelectionModel;
        selModel.SelectRange(count - 2, count - 1);
    }
</script>

    Thanks, exactly what I was looking for.

    I found to disable selection at all of the grid panel, but is there also a way of disable
    only multiselect?

    Please use SingleSelect to true.

    Example
    <ext:RowSelectionModel runat="server" SingleSelect="true" />
