repeater的几个用法

   

1.在Repeater的ItemDataBound事件中绑字数据项的值

 

protected void rpt_list_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        DataRowView gv = (DataRowView)e.Item.DataItem;
        Response.Write(gv["RoleName"].ToString());
    }

 

2.遍历checkbox项

        foreach (RepeaterItem ritem in rpt_list.Items)
        {
            CheckBox chk = (CheckBox)ritem.FindControl("chkRoleID");
            Label lbl = (Label)ritem.FindControl("lblRoleID");

            if (chk.Checked)
            {

                TextBox1.Text += lbl.Text;
            }

        }

 

3.全选checkbox

<input id="chkAll" type="checkbox" onclick="SelectAllCheckBox(this)" />

 

function SelectAllCheckBox(e)
{
    var form =document.forms[0];
   
    for(i=0;i<form.elements.length;i++)
    {
        if(form.elements[i].type=="checkbox")
        {
            form.elements[i].checked= e.checked;
        }
    }
}
