Gridview access from Javascript

[marksommerville]

I have a few questions regarding accessing a gridview control from
Javascript which I would really appreciate some help with.

1. The gridview contains a column of checkboxes as a template field. I
have onclick Javascript on the checkbox but can't figure out how to
determine the row number of the checkbox that was clicked.

2. How do I access a control within the gridview's pagertemplate? The
pagertemplate contains a 1 row table with a button in it that I need
to enable/disable.

Thanks.

Regarding for your first question: you can attach client-side script
within RowDataBound event handler:

<asp:GridView id="GridView1"
OnRowDataBound="GridView1_RowDataBound" ...
<Columns>
<asp:templateField>
<itemtemplate><sp:CheckBox id="CheckBox1" runat="server"></
itemtemplate>
</asp:templateField>

protected void GridView1_RowDataBound(object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox CheckBox1 = (CheckBox)e.Row.FindControl("CheckBox1");
CheckBox1.Attributes["onclick"] = string.Format("alert({0});",
e.Row.RowIndex);
}
}

This is for your 2nd?

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.GridViewRowEventArgs) Handles
GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.Pager Then
CType(e.Row.FindControl("Button1"), Button).Enabled = False
End If
End Sub

Thanks but I need to be able to access Button1 from Javascript. The
idea is that if no check boxes are checked then Button1 should be
disabled. My javascript function for the checkbox click will check to
see if all are unchecked then disable the button.
