具有相同事件的文本框数组(array of textboxes with the same event)

具有相同事件的文本框数组(array of textboxes with the same event)

我正在与c＃的窗体应用程序项目工作，我正在尝试使用相同的事件操作使TextBox数组。 我的意思是需要N个文本框（N与用户分配不同），而所有“TextBox_TextChanged”事件都是相同的。 如果你能帮助我，我会很感激。

I'm working on a windows form application project with c# and I’m trying to make an array of TextBox with the same event action. I mean N TextBoxes are required (N is different as user assign) while all the “TextBox_TextChanged “ event are same. I would appreciated it if you would help me.

请试试这个。

private void frmMain_Load(object sender, EventArgs e) { int userPermittedCount = 4 // You can add user defined permission no : of text box count here; int pointX = 30; int pointY = 40; for (int i = 0; i < userPermittedCount; i++) { TextBox txtBox = new TextBox(); txtBox.Location = new Point(pointX, pointY); this.Controls.Add(txtBox); this.Show(); pointY += 20; txtBox.TextChanged += txtAdd_TextChanged; } } private void txtAdd_TextChanged(object sender, EventArgs e) { }

Please try this.

private void frmMain_Load(object sender, EventArgs e) { int userPermittedCount = 4 // You can add user defined permission no : of text box count here; int pointX = 30; int pointY = 40; for (int i = 0; i < userPermittedCount; i++) { TextBox txtBox = new TextBox(); txtBox.Location = new Point(pointX, pointY); this.Controls.Add(txtBox); this.Show(); pointY += 20; txtBox.TextChanged += txtAdd_TextChanged; } } private void txtAdd_TextChanged(object sender, EventArgs e) { }
