Try this below or see more at:-

http://www.codeproject.com/aspnet/Multi-select_Dataagrid.asp?df=100&forumid=20837&exp=0&select=1620652#xx1620652xx

function SelectAllCheckBoxes(theBox, gvSelected)
{
var xState=theBox.checked;
var elm=theBox.form.elements;
var strElmID;

for(i=0;i<elm.length;i++)
{
strElmID = elm[i].id;
if(elm[i].type=="checkbox" && strElmID!=theBox.id && strElmID.indexOf(gvSelected)!=-1 )
{
if(elm[i].checked!=xState)
{
elm[i].click();
}
}
}
}

Notice I am now searching for a string gvSelected in the id of the checkbox. Since the .NET naming convention will name all of the checkboxes with concatenation and numbering, all we have to do is specify a different id for each checkbox column, and search for that as we cursor through all the elements on the page.

The following is the code for the first gridview and the beginning of the second:

<asp:GridView ID="gvDefHrs" runat="server" AutoGenerateColumns="false" DataKeyNames="emp_def_earn_uuid"
DataSourceID="SqlDataSource1" OnRowCommand="gvDefHrs_RowCommand" OnRowDataBound="gvDefHrs_RowDataBound">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<input id="chkAllDefHrs" runat="server" onclick="SelectAllCheckBoxes(this,'chkSelectDefHrs');"
type="checkbox" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkSelectDefHrs" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField ButtonType="Button" CommandName="EditDefHrs" Text="edit" />
<asp:BoundField DataField="earn_hrs" HeaderText="Hours" SortExpression="earn_hrs" />
<asp:BoundField DataField="emp_def_earn_uuid" HeaderText="UUID" SortExpression="emp_def_earn_uuid"
Visible="false" />
</Columns>
</asp:GridView>

<asp:GridView ID="gvDefDollars" runat="server" AutoGenerateColumns="false" DataKeyNames="emp_def_earn_uuid"
DataSourceID="SqlDataSource2" OnRowCommand="gvDefDollars_RowCommand" OnRowDataBound="gvDefDollars_RowDataBound">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<input id="chkAllDefDollars" runat="server" onclick="SelectAllCheckBoxes(this,'chkSelectDefDollars');"
type="checkbox" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkSelectDefDollars" runat="server" />
