增加标签和单选按钮并从数据库中检索 [英] increment the labels and radio buttons and retriving from database

问题描述

我在数据库中有一张表，想要检索数据并将其显示在网页中
这就是我所知道的

dr = dt.Rows [k];
Label1.Text = dr [0] .ToString();
RadioButton1.Text = dr [1] .ToString();
RadioButton2.Text = dr [2] .ToString();
RadioButton3.Text = dr [3] .ToString();
RadioButton4.Text = dr [4] .ToString();

请告诉我如何给它加油，以便我不应该一次又一次地复制和粘贴它.请给我代码...帮助我...

推荐答案

我是否已经向您解释过您不应该在Designer中创建单选按钮?这是没有道理的-手工无条件的无聊的不可靠的工作.而是用代码创建它们:

Did I already explain you that you should not create your radio buttons in Designer? It makes no sense — manual unqualified boring unreliable work. Create them in code instead:

RadioButton[] RadioButtons = new RadioButton[/*...*/];
for (int index = 0; index < RadioButtons.Length; ++index) {
    RadioButton rb = new RadioButton();
    RadioButtons[index] = rb;
    rb.Text = //... from some data file, resource, date set...
    rb.Left = //calculate it based on index and/or layout measures
    rb.Top = //calculate it based on index and/or layout measures
    rb.CheckedChanged += (sender, eventArgs) => {
        RaduoButton radioButtonSender = (RaduoButton)sender;
        //some handling using radioButtonSender and its status
    };
    rb.Parent = someRadioButtonParent; //some group or panel
}

如果执行此操作，所有操作将变得容易:

If you do this, all operations become easy:

for (int index = 0; index < RadioButtons.Length; ++index) {
    RadioButton[index].Text = dr[index];
    //...
}

尝试使用FindControl.

Try to use FindControl.

for (int index = 0; index < 200; index++) 
{
Control radioButton=yourContainer. FindControl("RadioButton"+i);
if(radioButton!=Null){

radioButton.Text= dr[i].ToString();

}

}
