如何给Datagridview添加一列checkbox，并且第一行设置全选复选框?

GridView1

<HeaderTemplate>
<input id="chkAll1" runat="server" type="checkbox" name="chkAll1" onclick="CheckAll(this,\'GridView1\');" />全选
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox runat="server" ID="cbx1" />
</ItemTemplate>

function CheckAll(oCheckbox,strGvlist)

var GridView1 = document.getElementById(strGvlist);

for(i = 0;i < GridView1.rows.length; i++)

GridView1.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = oCheckbox.checked;

参考技术A 在设置视图里面点击DataGridView右上角那个小三角，点击“编辑列”，“添加”，在弹出的“添加列”选项卡，类型选“DataGridViewCheckBoxColumn”
全选 只能放按钮吧 根webform不一样
this.dataGridView1.EndEdit();
for (int i = 0; i <dataGridView1.Rows.Count;; i++)

dataGridView1.Rows[i].Cells[0].Value = true;
参考技术B <asp:TemplateColumn>
<HeaderStyle Width="5px"></HeaderStyle>
<HeaderTemplate>
<asp:Button ID="Button1" runat="server" Text="全选" CssClass="btnSelect" CommandName="btn_sellall">
</asp:Button>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkAll" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
后台代码:
protected void DataGrid1_ItemCommand(object source, DataGridCommandEventArgs e)

if (e.CommandName == "btn_sellall")

CheckBox cb = new CheckBox();
int i, j = DataGrid1.Items.Count;
if (ViewState["CheckAll"].ToString() == "no")

for (i = 0; i < j; i++)

cb = (CheckBox)DataGrid1.Items[i].FindControl("chkAll");
cb.Checked = true;

ViewState["CheckAll"] = "yes";


else if (ViewState["CheckAll"].ToString() == "yes")

for (i = 0; i < j; i++)

cb = (CheckBox)DataGrid1.Items[i].FindControl("chkAll");
cb.Checked = false;

ViewState["CheckAll"] = "no";



这里的ViewState["checkAll"]保存的是选择的状态 pageLoad里面要加上
ViewState["checkAll"]="no";
