Trying to FindControl on a GridRecord is always getting null
posted

I have following code in my page:

<ig:WebDataGrid ID="AuditDataWebGrid" runat="server"
oncolumnsorted="AuditDataWebGrid_ColumnSorted"
ondatafiltering="AuditDataWebGrid_DataFiltering"
oncolumnmoved="AuditDataWebGrid_ColumnMoved"
oninitializerow="AuditDataWebGrid_InitializeRow"
EnableAjax="false" Width="100%" >
<Behaviors>
    <ig:ColumnMoving>
    </ig:ColumnMoving>
    <ig:Filtering>
    </ig:Filtering>
    <ig:Paging PageSize="25" PagerAppearance="Both" PagerMode="NextPreviousFirstLast">
 <PagerTemplate>
     <uc1:PagingUserControl ID="PagingUserControl" runat="server" />
 </PagerTemplate>
    </ig:Paging>
    <ig:Sorting SortingMode="Multi">
    </ig:Sorting>
</Behaviors>
<Columns>
    <ig:TemplateDataField Header-Text="" Key="IS_SELECTED">
 <HeaderTemplate>
     <asp:CheckBox ID="MultiSelectCheckBox" ToolTip = "Select/Deselect all rows" runat="server" AutoPostBack="true" OnCheckedChanged="MultiSelectCheckBox_OnCheckedChanged" />
 </HeaderTemplate>
 <ItemTemplate>
     <asp:CheckBox ID="IsSelectedCheckBox" runat="server" Enabled="true" AutoPostBack="true" OnCheckedChanged="IsSelectedCheckBox_OnCheckedChanged" />
 </ItemTemplate>
    </ig:TemplateDataField>
    <ig:TemplateDataField Header-Text="Status" Key="STATUS">
     <HeaderTemplate>
  <label>Status : </label>
  <asp:DropDownList ID="StatusFilterDropDownList" runat="server" DataTextField = "DisplayText" DataValueField = "AuditStatusId" AutoPostBack="true" OnSelectedIndexChanged="StatusFilterDropDownList_OnSelectedIndexChanged"></asp:DropDownList>
     </HeaderTemplate>
     <ItemTemplate>
  <asp:DropDownList ID="StatusDropDownList" AutoPostBack="false" runat="server" DataTextField="DisplayText" DataValueField="AuditStatusId">
  </asp:DropDownList>
     </ItemTemplate>                           
    </ig:TemplateDataField>
</Columns>
</ig:WebDataGrid>     

What I'm doing is looping through the WebdataGrid as follow:

foreach (GridRecord gridrow in AuditDataWebGrid.Rows)
{
    CheckBox chk = gridrow.FindControl("IsSelectedCheckBox") as CheckBox;

But I'm always getting chk = null.

What is the way to find this control in the GridRecord? or what should be the way to accomplish this?

Thanks

    Here is what I'm doing to get the control.

    foreach (GridRecord gridrow in AuditDataWebGrid.Rows)
    {
       CheckBox chk = gridrow.Items[AuditDataWebGrid.Columns["IS_SELECTED"].Index].FindControl("IsSelectedCheckBox") as CheckBox;
    }

    Now the problem is following: I know I checked the checkbox but when I got the control it say it is not checked.  Why value is not posted back?
