2. how can==>column[1].width=10;

Update :

If it is bound column

<asp:BoundColumn onClientClick="javascript:alert('blah blah');" />

If it is template column

<ItemTemplate>
    <div onclick="javascript:alert('Clicked');">
<asp:label text="blah blah" />
</div>
</ItemTemplate>

You mean something like this?

<div onclick="javascript:alert('Clicked');">
<asp:gridview runat="server">
</asp:gridview>
</div>
