in a aspx form have a textbox ans three buttons. on clicking each button textbox display different text. and all buttons click event call same function in aspx.cs file.

how do it.. plse help me..

推荐答案

如果要调用相同的函数，则必须传递一个参数来指示哪个button_click事件调用该函数.
那只有我能从您的问题中提出建议

If you are calling a same function then you have to pass one parameter to indicate which button_click event calling that function.
that only i can suggest from your question

那是什么问题?您可以使用按钮的ID进行检查.
试试这个:

Then what is the problem? You can check with the ID of the button.
Try this:

protected void buttonGroup_Click(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.ID == "Button1")
          TextBox1.Text = "Button1 clicked";
    else if(btn.ID == "Button2")
          TextBox1.Text = "Button2 clicked";
    else if(btn.ID == "Button3")
          TextBox1.Text = "Button3 clicked";
}
