hello,

i have a datagrid w/ a TemplateColumn in it, like so:

<asp:TemplateColumn HeaderText="Select">
<ItemTemplate>
<asp:CheckBox ID="chkSelected" Runat="server"/>
</ItemTemplate>
</asp:TemplateColumn>

....in my c# code-behind, how do i access the checkbox? i need to add a
javascript onClick attribute.

thanks!

perhaps i should clarify -- i want to access from Page_Load and add the
javascript Attribute to *all* the row's checkboxes. this way, each row
of grid has a server-side CheckBox w/ a javascript attribute tagged on.

tho maybe... i should do this from the grid's ItemDataBound or
ItemCreated events, and try to use a syntax like the one youve
provided.

this is what i was looking for:

public void Item_Bound(Object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
CheckBox chkSelected = (CheckBox)e.Item.FindControl("chkSelected");
chkSelected.Attributes.Add("onClick",
"setCheckboxClickCount(this.checked);");
}
}

In this blog, it shows you how to create "Select All" check boxes in
datagrid (I guess you are trying to do the same thing here.)
It attaches "onClick" event to the checkboxed in a datagrid using mostly
client side Javascript.
