Get the Text of dynamically created button in C#?

Question

I am dynamically creating buttons in C# with this logic

for (int i = 1; i <= vap; ++i)
{
    newButtons[i] = new Button();
    newButtons[i].BackColor = Color.Gray;
    newButtons[i].Name = "Button4" + i.ToString();
    newButtons[i].Click += new EventHandler(NewButtons_Click);

    newButtons[i].Location = new System.Drawing.Point(width,height);
    newButtons[i].Size = new System.Drawing.Size(76, 38);

    tabPage5.Controls.Add(newButtons[i]);
}

This is creating a button and the click event is also working but my problem is I don't know how to get the text of the newly created button. On form load I am putting the text of button from database and this also happening correctly, but I want to know how to get the text of dynamically created buttons.

Answer 1

You won't be able to get the text until after you populate it from the database (careful not to try and get the text too early).

But this should work:

string buttonText = FindControl("Button41").Text;

Update

Since you want the button text from within the click event, you can access the sender object:

Button button = sender as Button;
string buttonText = button.Text;

Answer 2

您只需在添加按钮时设置按钮的Text属性。

Answer 3

Using something along the lines of...

string BtnTxt = FindControl("ExampleButton1").Text;

should work fine.

This may cause problems later on however if you are trying to pull text content of buttons in a random order.
