问题描述

我的xml文件示例

< xmlScript xmlns.xsi =http // www.w3.org>

< / greeting>



< confirm>

<数据>这是琼斯先生< / data>

< / confirm>



< / xmlScript>

//和等等







以下代码将xmlscripts保存到myscript中



string scriptpath = Server.MapPath（/ xmlScript /+ ddlxmlScriptList.SelectedValue.ToString（））; //显示xml脚本的下拉列表（ddl）

xmlScript myscript = new xmlScript（scriptpath）;

myscript = myscript.LoadFile（）;

if（myscript.greeting！= null）

{





我如何填充*文本框中的myscript问候语*

}

an example of my xml file
<xmlScript xmlns.xsi="http//www.w3.org">
<greeting >
< data > hi how you doing today < /data >
</greeting >

<confirm >
< data > is this Mr Jones < /data >
</confirm >

</xmlScript>
// and so on



the following code saves the xmlscripts into myscript

string scriptpath = Server.MapPath("/xmlScript/" + ddlxmlScriptList.SelectedValue.ToString()); // drop down list (ddl) displaying the xml scripts
xmlScript myscript = new xmlScript(scriptpath);
myscript = myscript.LoadFile();
if (myscript.greeting != null)
{


How do i populate *myscript greeting* in a textbox??
}

推荐答案

确定 - 在代码隐藏中你需要覆盖onInit方法：

Ok - in the code-behind you need to override the onInit method:

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);
    ddlxmlScriptList.SelectedValueChanged += XmlScriptListSelectedValueChanged;
}

然后，当更改下拉列值时，将运行方法'XmlScriptListSelectedValueChanged（object sender，EventArgs e）'。 />


我知道我可能说的有点低于你的水平。原谅我，但我喜欢完全完整的答案，你确实提出了一个非常通用的问题:)



我知道你知道这个，因为这可能是你的代码获取xml生活。



如果不是这样，那么也许你有一个按钮。同样的原则适用。只要您的页面仍然处于加载状态（例如当事件在后面的代码中运行时，即XmlScriptListSelectedValueChanged（sender，e））那么这是 where <和b> 你需要填充文本框。



填充文本框只是将字符串分配给文本框的Text属性：

Then, when the dropdown value is changed, the method 'XmlScriptListSelectedValueChanged(object sender, EventArgs e)' will run.

I know I am probably talking a bit below your level. Forgive me but I like fully complete answers and you did ask a very generic question :)

I know you know this because this is probably when your code to fetch the xml lives.

If that is not the case then perhaps you have a button. The same principle applies. As long as you have the page still in a loading state (such as when an event is running in the code behind, i.e. XmlScriptListSelectedValueChanged(sender,e)) then this is where and when you need to populate the text-box.

Populating the text-box is simply a case of assigning a string to the textbox's Text property:

XmlScriptListSelectedValueChanged(object sender, EventArgs e){
    
    string theValueINeedInTheTextbox = SomeXmlLoadingStuff(ddlxmlScriptList.SelectedValue);
    tbxTheTextbox.Text = theValueINeedInTheTextbox; 
}

如果我已回答你的问题，请告诉我^ _ ^
