ASPxCheckBox inside ASPxGridView - The CheckedChanged event is not raised when the grid is filtered

Hi Vest,
Thanks for your inputs. I have given below the complete page now, excluding the master page related stuff.
<dxwgv:ASPxGridView ID="GV_List" ClientInstanceName="GV_List" runat="server"
            AutoGenerateColumns="False" KeyFieldName="ContentKey" Width="100%" >
        <Settings ShowFilterRow="true" ShowFilterRowMenu="true" ShowTitlePanel="true" />
        <SettingsText Title="Manage" />
        <Styles AlternatingRow-BackColor="#efefef" Header-HorizontalAlign="Center"/>
        <Columns>
            <dxwgv:GridViewDataTextColumn Caption="Display" FieldName="DisplayIndicator" VisibleIndex="0" >
                <DataItemTemplate>
                    <dxe:ASPxCheckBox ID="cbDisplayIndicator" runat="server" AutoPostBack="true"
                        ClientInstanceName='<%# string.Format("check_{0}_{1}", Eval("Key"), Eval("Type"))%>'
                        ValueType="System.String" ValueChecked="1" ValueUnchecked="0"
                        Checked='<%# System.Convert.ToBoolean(Eval("DisplayIndicator")) %>'
                        OnCheckedChanged="DisplayIndicator_CheckedChanged">
                    </dxe:ASPxCheckBox>
                </DataItemTemplate>

<CellStyle HorizontalAlign="Center"/>
            </dxwgv:GridViewDataTextColumn>
            <dxwgv:GridViewDataTextColumn Caption="Name" FieldName="Name" VisibleIndex="1">
                <Settings AutoFilterCondition="Contains" />
            </dxwgv:GridViewDataTextColumn>
        </Columns>
        <Settings ShowFooter="true" ShowGroupPanel="True" />
    </dxwgv:ASPxGridView>
.aspx.cs
-----------
     protected void Page_Load(object sender, EventArgs e)
        {
            if ((!Page.IsPostBack) || (Page.IsCallback))
            {
                BuildList();
            }
        }
        protected void BuildList() {

dbAccess dbData = new dbAccess();
            dbData = new dbAccess();
            DataSet dataset = new DataSet();
            dataset = dbData.getDataSetwithStoredProc("IND_List");

GV_List.DataSource = dataset;
            GV_List.DataBind();
        }
     protected void DisplayIndicator_CheckedChanged(object sender, EventArgs e)
        {
            ASPxCheckBox checkbox = (ASPxCheckBox)sender;
            string sCheckValue = checkbox.Value.ToString();
            GridViewDataItemTemplateContainer container = checkbox.NamingContainer as GridViewDataItemTemplateContainer;
            int rowIndex = container.VisibleIndex;
            string _key = GV_IndicatorList.GetRowValues(rowIndex, new string[] { "Key" }).ToString();
            string _type = GV_IndicatorList.GetRowValues(rowIndex, new string[] { "Type" }).ToString();
            // Things to be done w/ _key & _type
        }
Steps to reproduce:
When the grid loads for the first time, setting a break point anywhere in DisplayIndicator_CheckedChanged is always hit. But if i filter the grid by some text and then click on the checkboxes, breakpoints in DisplayIndicator_CheckedChanged is not hit.
Hope this helps… I will also look in to the sample you have linked to. Thanks!

Hello Karthik:
We are working on this problem and will answer you as soon as possible. Please accept our apologies for the delay.
Thanks

Hello Karthik,
In your code snippet, I see that you do not bind ASPxGridView during postbacks. However, according to the ASP.NET Page Life Cycle, you must provide controls with data on each round trip to the server. So, please delete the condition below. It should resolve your issue.

C#
protected void Page_Load(object sender, EventArgs e)    {  
     //if ((!Page.IsPostBack) || (Page.IsCallback))                        << - delete this condition  
                BuildList();  

}  

Moreover, I suggest that you update the ASPxCheckBox value via callbacks rather than postbacks. You can find how to implement this approach in an example suggested by Vest.
Thanks,
Marion
