[CLOSED] GridPanel RowSelectModel donÂ´t working

**supera** · Jan 23, 2012, 3:38 PM

Hi...

I am doing something wrong, probably!

I declare in my GridPanel the Selection Model as follows

<SelectionModel>
   <ext:RowSelectionModel runat="server" Mode="Single" />
</SelectionModel>

I have a button, called btnDetails, when i call with DirectEvent the protect sub ShowDetails

<ext:Button runat="server" ID="btnDetails" Icon="ApplicationEdit" Text="Detalhar">
     <DirectEvents>
         <Click OnEvent="ShowDetails" 
                   Failure="Ext.MessageBox.alert('Load failed', 'Error during ajax event!');">
                  <EventMask ShowMask="true" Target="CustomTarget" CustomTarget="={#{grdSugestoes}.body}" />
         </Click> 
     </DirectEvents>
</ext:Button>

But, in ShowDetail, the collection SelectedRows allways return 0 in count property, although a selected line in the grid

Protected Sub ShowDetails(sender As Object, e As Ext.Net.DirectEventArgs)
        Dim sm As Ext.Net.RowSelectionModel = Me.grdSugestoes.GetSelectionModel()
        Dim row As Ext.Net.SelectedRow
        
        If sm.SelectedRows.Count > 0 Then
            row = sm.SelectedRows(0) 'Pode ter mais de uma selecioanda, mas pego a primeira, sempre
            Me.wndSugestoesDetail.Start(Convert.ToInt64(row.RecordID.ToString), grdSugestoes.GetStore())
        Else
            Dim msg As New Ext.Net.MessageBox
            msg.Alert("REGISTRO NÃO SELECIONADO", "Por favor, selecione um registro na lista para ver o detalhamento!")
            msg.Show()
        End If
                
    End Sub

Hi,

Confirmed, this is a bug. We will investigate.

Thanks for the report.

For now, I can suggest to send required data via an extra parameter.

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[] { "test1", "test2", "test3" },
                new object[] { "test4", "test5", "test6" },
                new object[] { "test7", "test8", "test9" },
            };
            store.DataBind();
        }
    }

    protected void GetSelectedCount(object sender, DirectEventArgs e)
    {
        SelectedRowCollection selectedRows = JSON.Deserialize<SelectedRowCollection>(e.ExtraParams["selection"]);
        X.Msg.Alert("Count", selectedRows.Count).Show();
    }
