获取文本框的文本是动态创建的 [英] getting the textbox's text which was created dynamically

问题描述

大家好
我在运行时创建了多个TextBox es，还编写了TextBox es的click事件，当我单击TextBox即(在运行时创建的)时，我想获取<TextBox的c3>.

创建TextBox取决于数据库.

Hi to all
I had created a number of TextBoxes in runtime, I had also writen the click event for the TextBoxes, when I click on the TextBox i.e (which was created in runtime), I want to get the Text of TextBox .

Creating the TextBox depends on a database.

TextBox t = new TextBox();
t.Text = dr["temp1"].ToString();
t.BackColor = Color.CadetBlue;
t.WordWrap = true;
t.Multiline = true;
t.ReadOnly = true;
t.HideSelection = true;
t.Size = new Size(610, 50);
t.Name = "temptxt";
t.Click += new System.EventHandler(t_Click);
pan.Controls.Add(t);

我尝试了很多，但没有用.我还尝试过隐藏CheckBox，因为我不应该在那个地方使用CheckBox，但是我无法获得所单击的TextBox的Text.

I had tried a lot but no use. I had also tried by keeping the CheckBox hidden, because I should not use the CheckBox at that place, but I am not able to get the Text of the clicked TextBox.

推荐答案

在Click事件处理程序中，您将有一个参数"sender"-这是导致事件的TextBox:

In the Click event handler, you will have a parameter "sender" - this is the TextBox that caused the event:

TextBox t = sender as TextBox;
if (t != null)
   {
   Console.WriteLIne(t.Text);
   }

在TextBox
的Click事件处理程序中使用以下代码

Use the following code in the Click event handler of the TextBox

void t_Click(object sender, EventArgs e)
{
    TextBox t1 = (TextBox)sender;
    string str = t1.Text; 
}
