【Asp.Net】 GridView中CheckBox,RadioButton并存的同时且有相互关

作者:qfb620/ / 发布于2014/1/22/ 604

在GridView中一列存放CheckBox,一列存放RadioButton;并且选择了CheckBox才能激活同行的RadioButton.

前台文件

<asp:GridView ID="GridView1" runat="server" Width="99%" AutoGenerateColumns="False"
 SkinID="GridViewskin"onrowdatabound="GridView1_RowDataBound">
 <Columns>
 <asp:TemplateField HeaderText="编号" ItemStyle-Width="25%">
 <ItemTemplate>
 <%#Eval("ID")%>
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="名称" ItemStyle-Width="25%">
 <ItemTemplate>
 <%#(Eval("Name"))%>
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="设置" ItemStyle-Width="25%">
 <ItemTemplate>
 <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true"
 oncheckedchanged="CheckBox1_CheckedChanged" />
 </ItemTemplate>
 </asp:TemplateField>
 <asp:TemplateField HeaderText="默认" ItemStyle-Width="25%">
 <ItemTemplate>
 <asp:RadioButton ID="RadioButton1" runat="server" />
 </ItemTemplate>
 </asp:TemplateField>
 </Columns>

 </asp:GridView>



<script type="text/javascript">
 var last=null;
 function single(obj)
 {
 if(last==null) //第一次选择RadioButton时赋id值给last
 {
 last=obj.id;
 }
 else //第一次以后的每一次都在这运行，把上此的RadioButton.Checked=false,记下此次的obj.name
 {
 var lo=document.getElementById(last);
 lo.checked=false;
 last=obj.id;
 }
 obj.checked="checked"; //添加checked属性，以便在上边赋值为false
 }
 </script>





后台CS

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
 if (e.Row.RowType == DataControlRowType.DataRow)
 {
 RadioButton rb = (RadioButton)e.Row.FindControl("RadioButton1");
 if (rb != null)
 {
 rb.Attributes.Add("onclick", "single(this)"); //single(obj)为js函数
 rb.Enabled = false;
 }
 }
 }

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
 {
 for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
 {
 CheckBox cbox = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
 RadioButton rbtn = (RadioButton)GridView1.Rows[i].FindControl("RadioButton1");
 if (cbox.Checked == true)
 {
 cbox.Checked = true;
 rbtn.Checked = false;
 rbtn.Enabled = true;
 }
 else
 {
 rbtn.Checked = false;
 rbtn.Enabled = false;
 }
 }
 }
