Hello,

I'm using Infragistics v12.1.

I have a webdatagrid like this:

<ig:WebDataGrid EnableDataViewState="true" ID="wdgPorAlocar" runat="server" Height="100%" Width="100%" AutoGenerateColumns="False" EnableAjax="False" ShowFooter="true">   

<Columns>      

<ig:TemplateDataField Key="Alocar_" Width="20px">         

    <HeaderTemplate>  
       <div style="text-align: left;">               
            <input type="checkbox" onclick="checkAll1(event);" />            
       </div>         
    </HeaderTemplate>         
    <ItemTemplate>       
        <div style="text-align: left;">               
             <asp:CheckBox ID="Key_" runat="server" Checked='<%# Eval("Alocar") %>' />            
        </div>       
     </ItemTemplate>      

</ig:TemplateDataField>      

...    

</Columns>   

<ClientEvents Initialize="intializeGrid1" ="intializeGrid1" />   
<Behaviors>       ...  </Behaviors>

</ig:WebDataGrid>

Here's the javascript code:

<script type="text/javascript">

        var webDataGrid1;

        function intializeGrid1(grid) {            
            webDataGrid1 = grid;        
        }

        function checkAll1(evnt) {

            var chkBox = evnt.target ? evnt.target : evnt.srcElement;

            for (var i = 0; i < webDataGrid1.get_rows().get_length(); i++) {                
                webDataGrid1.get_rows().get_row(i).get_cellByColumnKey("Alocar_").get_element().all(0).all(0).checked = chkBox.checked;            
            }        
         }

 </script>

When I click the header checkbox of column "Alocar_" I want all the checkbox of the grid rows to be selected. This works fine in IE. But it doesn't work on firefox, it says that webDataGrid1.get_rows().get_row(i).get_cellByColumnKey("Alocar_").get_element().all is not a valid funcion. How can I achieve this in firefox?

Thank you
