获取页面加载时选择的RadioButtonList项 [英] Get RadioButtonList Item selected on page load

问题描述

我有一个带有两个项目的RadioButtonList:值为"1"的"Administrator"和值为"2"的"User".我想基于存储在数据库中的值获取要在页面加载时选择的单选按钮列表项. RadioButtonList所选项目的值存储在数据库中，并且位于int变量"ug"中.我已经尝试了以下代码:

Hi,

I''m having a RadioButtonList with two items: "Administrator" with value ''1'' and "User" with value ''2''. I want to get the radiobutton list item to be selected on page load based on the value stored in the database. Value of the RadioButtonList selected item is stored in the database, and it is there in the int variable ''ug''. I''ve tried the following codes:

if (ug == '1')
                //rbl1.SelectedItem.Text = "Administrator";
                //rbl1.SelectedItem.Value = "1";
                rbl1.SelectedIndex = 0;
                //rbl1.Items[0].Selected = true;
            else
                //rbl1.SelectedItem.Text = "User";
                //rbl1.SelectedItem.Value = "2";
                rbl1.SelectedIndex = 1;
                //rbl1.Items[1].Selected = true;

但是，它对我不起作用.有人请帮助我...

谢谢

But, it is not working for me. Anyone please help me....

推荐答案

<asp:RadioButtonList ID="rb" runat="server">
       <asp:ListItem Text="Administrator" Value="1"></asp:ListItem>
       <asp:ListItem Text="User" Value="2"></asp:ListItem>
   </asp:RadioButtonList>

string ug = "1";
        if (ug == "1")
            rb.SelectedValue = ug;
        else
            rb.SelectedValue = ug;

if(ug == "1")
{
    rbl1.selectedvalue = ug;
}
else
{
    rbl1.selectedvalue = ug;
}

我尝试过:

Hi,
I''ve tried:

rbl1.SelectedValue = ug.ToString();

工作正常.

谢谢.

It''s working fine.

Thank You.
