推荐答案
这样的事情如何:
How about something like this:
protected void Button1_Click ( object sender, EventArgs e )
{
IEnumerable<TextBox> tboxes = this.Controls.OfType<TextBox> ();
TextBox txtbx = tboxes.First<TextBox> ( t => t.ID == "txt1" );
txtbx.Text = "something";
}
请尝试:
在aspx.cs中:
Please try:
In aspx.cs:
public void addButton()
{
//setText() is a javasript function to set to 10 textboxes, examples
/*
* function setText()
* {
* txt0.value = 'textbox0';
* txt1.value = 'textbox1';
* txt2.value = 'textbox2';
* txt3.value = 'textbox3';
* //Etc...
* }
*/
Response.Write("<input type="button" önclick="setText();" value="Click Me" /> <br />");
}
public void addTextBoxes()
{
for (int i = 0; i < 10; i++)
{
Response.Write("<input id="txt" + i.ToString() + "" type="textbox" /> <br />");
}
}
在aspx中:
In aspx:
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript">
function setText(){
form1.txt0.value = ''textbox0'';
form1.txt1.value = ''textbox1'';
}
</script>
</head>
<body>
<form id="form1" runat="server">
<%addButton(); %>
<%addTextBoxes(); %>
</form>
</body>
问候.

[textboxID] .Text ="whatever";
将其放在按钮单击事件处理程序中.
没有看到ASP.Net标记. :doh:
由于这些是动态创建的控件，因此AFAIK您必须在回发时重新创建它们.重新创建时，您可以检查回发是否是由于单击按钮引起的，如果是，则设置文本.
[textboxID].Text = "whatever";
Put this in button click event handler.
Did not saw ASP.Net tag. :doh:
Since these are dynamically created controls, AFAIK you will have to recreate them on post back. While recreating, you can check if the postback is because of button click and if yes, set the text.
