How to set focus on dynamically created controls using C#.net windows application

txtsrno = new TextBox();
            txtsrno.Name = "a1" + nn.ToString();
            txtsrno.Location = new Point(6, y);
            txtsrno.Size = new Size(59, 20);
            txtsrno.Text = sno.ToString();
            txtsrno.TabIndex = txt_amount.TabIndex + 1; // this is not working. 
            panel1.Controls.Add(txtsrno);

推荐答案

将控件添加到panel1后，请尝试调用Focus方法.

Once added the control to the panel1, try calling the Focus method.

txtsrno.Focus();

简短说明一下Mario的正确答案，只是为了结束这一话题:所有控件总是始终创建并动态添加.如果您认为设计器做了一些不同的事情，请再考虑一下.设计器仅帮助您在设计时创建代码.运行时发生的事情恰好是您在应用程序中所做的事情.查看设计器自动生成的C#代码以查看它.

A short note to the correct answer by Mario, just to close the topic: all controls are always created and added dynamically. If you think the Designer does something different, think again. The designer only helps you to create the code during design-time. What happens during runtime is exactly what you do in your application. Look at the C# code auto-generated by the Designer to see it.
