如果没有图片的话，也能明白，就是，我的页面上放了textBox，这些textBox是手动在后台中自动生成的，然后，现在需要给这些textbox添加TextChanged事件，注：这是服务器控件，让我的页面上的每个生成的TextBox都具有TextChanged事件
解决方案1: protected override void OnInit(EventArgs e)
{
base.OnInit(e);
TextBox box = new TextBox();
box.TextChanged+=new EventHandler(box_TextChanged);
Page.Controls.Add(box);
}
protected void box_TextChanged(object sender, EventArgs e)
{ }
解决方案2: protected override void OnInit(EventArgs e)
{
base.OnInit(e);
TextBox box = new TextBox();
box.TextChanged+=new EventHandler(box_TextChanged);
Page.Controls.Add(box);
}
protected void box_TextChanged(object sender, EventArgs e)
{ }
解决方案3:
TextBox txtRemark2 = (TextBox)e.Row.FindControl("txt_Time2");
txtRemark2.TextChanged += new EventHandler(....);
解决方案4: protected void Page_Load(object sender, EventArgs e)
{
TextBox tb1 = new TextBox();
TextBox tb2 = new TextBox();
tb1.AutoPostBack = true;
tb1.TextChanged += new EventHandler(tb1_TextChanged);
tb2.AutoPostBack = true;
tb2.TextChanged += new EventHandler(tb2_TextChanged);
div_txt.Controls.Add(tb1);
div_txt.Controls.Add(tb2);
}
protected void tb2_TextChanged(object sender, EventArgs e)
{
Response.Write(((TextBox)sender).Text);
}
protected void tb1_TextChanged(object sender, EventArgs e)
{
Response.Write(((TextBox)sender).Text);
}
正解
解决方案5: TextBox txt=new TextBox();
txt.ID="txt";
txt.TextChanged +=new EventHandler(textBox_TextChanged);
this.Controls.Add(txt);
private void textBox_TextChanged(object sender, EventArgs e)
{
TextBox tb = (TextBox)sender;
}
解决方案6:
protected void Page_Load(object sender, EventArgs e)
{
TextBox tb1 = new TextBox();
TextBox tb2 = new TextBox();
tb1.AutoPostBack = true;
tb1.TextChanged += new EventHandler(tb1_TextChanged);
tb2.AutoPostBack = true;
tb2.TextChanged += new EventHandler(tb2_TextChanged);
div_txt.Controls.Add(tb1);
div_txt.Controls.Add(tb2);
}
protected void tb2_TextChanged(object sender, EventArgs e)
{
Response.Write(((TextBox)sender).Text);
}
protected void tb1_TextChanged(object sender, EventArgs e)
{
Response.Write(((TextBox)sender).Text);
}
