推荐答案

< asp：gridview id =gridrunat =serverxmlns：asp =＃unknown>

< columns> < asp：templatefield>

< headertemplate>

< asp：checkbox id =OneCheckBoxAllrunat =servertext =[Check All] previously Assigned >

onclick =checkAll（''oneCheckBox''，this）; />

< / headertemplate>

< itemtemplate>



< asp：checkbox id =oneCheckBoxrunat =servertext =<％＃Eval（one）％> />





< asp：templatefield>

< headertemplate>

< asp：checkbox id =TwoCheckBoxAllrunat =servertext =[Check All] Currently assigned>

onclick =checkAll（''TwoCheckBox''，this）; />

< / headertemplate>

< itemtemplate>



< asp：checkbox id =TwoCheckBoxrunat =servertext =<％＃Eval（two）％> />













以上是有多个复选框的网格



javascript是







< script type =text / javascript>

函数checkAll（fieldsname，field）

{

var n = aspnetForm.elements.length;

for（var i = 0; i< n; i ++）>

{

if（aspnetForm.elements [i] .id.indexOf（fieldsname）！= - 1）

{

aspnetForm.elements [i ] .checked = field.checked;

}

}

}

< / script>

<asp:gridview id="grid" runat="server" xmlns:asp="#unknown">
<columns> <asp:templatefield>
<headertemplate>
<asp:checkbox id="OneCheckBoxAll" runat="server" text="[Check All] Previously Assigned">
onclick="checkAll(''oneCheckBox'',this);" />
</headertemplate>
<itemtemplate>

<asp:checkbox id="oneCheckBox" runat="server" text="<%#Eval("one")%>" />


<asp:templatefield>
<headertemplate>
<asp:checkbox id="TwoCheckBoxAll" runat="server" text="[Check All] Currently Assigned">
onclick="checkAll(''TwoCheckBox'',this);" />
</headertemplate>
<itemtemplate>

<asp:checkbox id="TwoCheckBox" runat="server" text="<%#Eval("two")%>" />






above is grid with multiple checkboxes

javascript is



<script type="text/javascript">
function checkAll(fieldsname,field)
{
var n=aspnetForm.elements.length;
for (var i=0;i<n;i++)>
{
if (aspnetForm.elements[i].id.indexOf(fieldsname) !=-1)
{
aspnetForm.elements[i].checked = field.checked;
}
}
}
</script>

这里有一个我用过的样本检查并根据你的要求修改

here is a sample i''ve used check it and modify as per your requirement

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

            DataKeyNames="empid" DataSourceID="ObjectDataSource1">

            <Columns>

                <asp:TemplateField HeaderText="empid" SortExpression="empid">
                    <EditItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("empid") %>'></asp:Label>
                    </EditItemTemplate>
                    <HeaderTemplate>
                        <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True"

                            oncheckedchanged="CheckBox1_CheckedChanged" />
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="CheckBox2" runat="server" Text='<%# Eval("empid") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="empname" SortExpression="empname">
                    <EditItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("empname") %>'></asp:TextBox>
                    </EditItemTemplate>
                    <HeaderTemplate>
                        <asp:CheckBox ID="CheckBox4" runat="server" AutoPostBack="True"

                            oncheckedchanged="CheckBox4_CheckedChanged" />
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:CheckBox ID="CheckBox3" runat="server" Text='<%# Eval("empname") %>' />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="age" HeaderText="age" SortExpression="age" />
            </Columns>
        </asp:GridView>

C＃代码

C# code for that

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
   {
       CheckBox cb1selall = GridView1.HeaderRow.FindControl("CheckBox1") as CheckBox;
       for (int i = 0; i < GridView1.Rows.Count; i++)
       {
           CheckBox cb1 = GridView1.Rows[i].FindControl("CheckBox2") as CheckBox;
           if (cb1selall.Checked)
           {
               cb1.Checked = true;
           }
           else
           {
               cb1.Checked = false;
           }

       }
   }
   protected void CheckBox4_CheckedChanged(object sender, EventArgs e)
   {
       CheckBox cb2selall = GridView1.HeaderRow.FindControl("CheckBox4") as CheckBox;
       for (int i = 0; i < GridView1.Rows.Count; i++)
       {
           CheckBox cb1 = GridView1.Rows[i].FindControl("CheckBox3") as CheckBox;
           if (cb2selall.Checked)
           {
               cb1.Checked = true;
           }
           else
           {
               cb1.Checked = false;
           }

       }
   }
