Repeater 中CheckBox实现多选

全选JS

<script language="javascript" type="text/javascript">
function selectAll(f,mode)
{
	if(mode==true)
	{
	    for(i=0;i<f.length;i++)
	    {
		    if(f.elements[i].type=="checkbox")
		    {
			    f.elements[i].checked=true;
		    }
	    }
	}
	else
	{
	    for(i=0;i<f.length;i++)
	    {
		    if(f.elements[i].type=="checkbox")
		    {
			    f.elements[i].checked=false;
		    }
	    }
	}
}
    
    </script>

repeater中<input type="checkbox" name="Checkbox1222" onclick="javascript:selectAll(this.form,this.checked)" />实现全选。

<input id="Checkbox1" name="Checkbox1" type="checkbox" value="<%#Eval("ID") %>"   />

方法一：<asp:CheckBox ID="CheckBox2"  runat="server"  />
                    <asp:Label ID="Label1" runat="server"  Visible="false" Text ='<%#Eval("Photoid") %>' ></asp:Label>

　　LinkButton事件

    protected void LinkButton1_Click(object sender, EventArgs e)
    {
          string checkbox = Request["Checkbox1"];
          if (checkbox == null || checkbox == String.Empty)
          {
                Common.JsUtil.ShowMsgRedirect("请先选择要删除的信件!", "Default.aspx", "1");
          }
          else
          {
                String[] CheckboxArray1 = checkbox.Split(',');
                for (int i = 0; i < CheckboxArray1.Length; i++)
                {
                      Response.Write(CheckboxArray1[i]);
                }
          }
     }

方法二：<input id="Checkbox1" name="Checkbox1" type="checkbox" value="<%#Eval("Photoid") %>"   />

    protected void LinkButton1_Click(object sender, EventArgs e)
    {
          for (int i = 0; i < this.Repeater1.Items.Count; i++)
          {
                System.Web.UI.WebControls.CheckBox checkbox2 = (System.Web.UI.WebControls.CheckBox)Repeater1.Items[i].FindControl("CheckBox2");
                if (checkbox2.Checked == true)
                {
                      System.Web.UI.WebControls.Label labelID = (System.Web.UI.WebControls.Label)this.Repeater1.Items[i].FindControl("Label1");
                      Response.Write(labelID.Text);
                }
          }
    }
