    [CLOSED] Question about store

    Hello

    I have a little problem.

    I have a lot of data to display. as my data are grouped, I choose to display them in elven grid, representing each one one of the group od data.

    For the moment, I have one store per grid, but to optimize data dransfert, I will try to have only one store and diaplaying only relevant data of each gid with that store.

    The problem seem to be that I can't set the same store for different grid.

    If I try to put it like that :

            
        grdOSA.Store.Add(stoOSA)
        grdMASK.Store.Add(stoOSA)
    I get an error on execution that said taht the store is already assign

    and if I try by the storeID of the grids, I see data in first grid but in the second, all is replaced by "undefined" in value.

    Is there a way to achieve that?

    And after that, I wish to use again the same store to draw charts.

    Hi,

    Yes, the same Store cannot be added to Store collection of two GridPanels.

    So, you are right that you are trying to use StoreID.

    and if I try by the storeID of the grids, I see data in first grid but in the second, all is replaced by "undefined" in value.
    I am unable to reproduce this problem using the example below. Could you provide a sample?

    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[] { "test1", "test2", "test3" },
                new object[] { "test4", "test5", "test6" },
                new object[] { "test7", "test8", "test9" },
            };
            this.Store1.DataBind();
        }
    }
</script>

    What I want to achieve is that:

    <%@ 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[] { "test1", "test2", "test3", "test11", "test21", "test31" },
                new object[] { "test4", "test5", "test6", "test41", "test51", "test61" },
                new object[] { "test7", "test8", "test9", "test71", "test81", "test91" },
            };
            this.Store1.DataBind();
        }
    }
</script>

    I would ensure ModelFields Names and Columns DataIndexes are correct.
