Cannot update fields in Gridview when in "Edit" mode, asp validators prevents updating

Question

On my final year project I'm using a GridView that use an ObjectDataSource to show database data. My ObjectDataSource is linked with proper "select", "update", "delete" functions that are part of a N-Tiers application.

I've tested all my functions and they work well.

But when in "Edit" mode of the GridView I cannot update my fields... However I can delete rows well.

Any suggestions?

Thanks!

UPDATE: The problem is that my asp client-side validators are preventing me from submitting the updated field in "edit" mode. I've added them to the code.

Partial code:

<form id="form1" runat="server">
<div>        
    <asp:ObjectDataSource ID="BeersObjectDataSource" runat="server"

        SelectMethod="RetrieveBeers_BLL" 
        UpdateMethod="UpdateBeer_BLL"
        TypeName="BLL" >
        <DeleteParameters>
            <asp:Parameter Name="id" Type="Int32" />

Answer 1

That answer help me: Why asp.net validators prevent all other postback?

I've made a ValidationGroup:

Added the property ValidationGroup="AddBeerValidationGroup" to each CustomValidator

Partial modified Code behind:

protected void Button1_Click(object sender, EventArgs e)
{
    Page.Validate("AddBeerValidationGroup");

    if (Page.IsValid == true)
    {  /* SOME CODE ..... */    }
}
