ASP.NET 判断GRIDVIEW的checkbox是否选中

C# 实现

protected void btSubmit_Click(object sender, EventArgs e)
{
List<CheckBox> chkList = new List<CheckBox>();
foreach (GridViewRow row in this.GVReport.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chk = row.FindControl("cbActionFlag") as CheckBox;
if (chk.Checked)
{
chkList.Add(chk);
}
}
}
if (chkList.Count == 0)
{
ClientScript.RegisterStartupScript(typeof(string), "msgChk", "alert('please select active flag!');", true);
}
}

Jquery 实现

<script type="text/jscript" language="javascript" src="<%=ResolveUrl("~/js/jquery-1.5.2.js") %>"></script>
<script type="text/javascript">
var CHK_ACTION_FLAG = function(){
$("#<%=btSubmit.ClientID%>").click(function(){
var arrList = $("table[id$='GVReport']").find("[id$='cbActionFlag']:checked");
if( arrList.length >0){ return true;}
else{ return false;}
});
}
$(document).ready(CHK_ACTION_FLAG);
</script>
