我有动态创建的TextBox的这个问题.
当在PageLoad中创建TextBox时,它被TextChanged事件触发.
但是当我动态地删除并重新创建了TextBox时,TextChanged没有触发.
这是代码：
的.aspx
<body>
<form id="form1" runat="server">
<div>
<asp:Table ID="Table1" runat="server">
<asp:TableRow>
<asp:TableCell ColumnSpan="2">Fixed content</asp:TableCell>
</asp:TableRow>
</asp:Table>
</form>
</body>
的.cs
public partial class test：System.Web.UI.Page
{
string myText =“a”;
protected void Page_Load(object sender,EventArgs e)
{
WriteRows();
}
private void WriteRows()
{
TableRow tr = new TableRow();
TableCell tc = new TableCell();
TextBox txt = new TextBox();
txt.Text = myText;
txt.TextChanged += new EventHandler(txt_TextChanged); // Assign event handler
tc.Controls.Add(txt);
tr.Controls.Add(tc);
tc = new TableCell();
tc.Text = txt.Text;
tr.Controls.Add(tc);
Table1.Controls.AddAt(1,tr);
}
private void txt_TextChanged(object sender,EventArgs e)
{
myText = ((TextBox)sender).Text;
RedrawTable(); // Delete the row (incl. the TextBox) and rewrite it
}
private void RedrawTable()
{
Table1.Controls.RemoveAt(1);
WriteRows();
}
}
有没有人有解决方案,以便事件总是被触发？
