问题描述

从sql server数据库填充数据。



ASP代码

Data is populated from sql server database.

ASP Code

<asp:Repeater ID="rptProfession" runat="server">
  <itemtemplate>
    <asp:RadioButton id="rdbUser" runat="server" />
  </itemtemplate>
</asp:Repeater>

C＃代码：按钮后面

C# Code:Behind button

public void Submit_Evaluation(Object s, EventArgs e)
{
  foreach (RepeaterItem item in rptProfession.Items)
  {
    if (item.ItemType == ListItemType.Item)
    {
      RadioButton rb = (RadioButton) item.FindControl("rdbUser"); 
  
      if (rb.Checked)
      {
        lblMessage.Text = "Good";
      }
      else
      {
        lblMessage.Text = "Bad";
      }
    }
}

推荐答案

已完成......

< asp：repeater id =rptProfessionrunat =serverxmlns：asp =＃unknown>

< itemtemplate>

< asp ：radiobutton id =rdbUserautopostback =truerunat =server>







C＃代码：与上面相同。



只需

将DataBind代码放入Page_Init过程，这样无线电按钮的状态将是在到达Page_Load程序时设置。

并设置单选按钮的AutoPostBack =true。

Its done ...
<asp:repeater id="rptProfession" runat="server" xmlns:asp="#unknown">
<itemtemplate>
<asp:radiobutton id="rdbUser" autopostback="true" runat="server">



C# Code: Same as above.

Just
Putting DataBind code in the Page_Init procedure, that way the state of the radiobuttons will be set by the time it reaches the Page_Load procedure.
and Set AutoPostBack="true" of Radio Button.
