如何以windws形式向tablelayoutpanel添加新行 [英] How to add a new row to tablelayoutpanel in windws form

问题描述

我创建了一个带有tablelayout面板的win表单应用程序。

点击按钮我想重复一遍上面的行与控件和数据源相同，但选择清楚。

怎么做？

你好NirajZ，

如果你想重复控制，你必须先克隆它，众所周知，控件都是类，所以你也有要深入复制它们，请参考以下克隆类：

 public class ControlFactory 
 {
 public ControlFactory（）
 {
 // 
 // TODO：在这里添加构造函数逻辑
 // 
} 
 
 public static控件CreateControl（string ctrlName，string partialName） 
 {
尝试
 {
控制ctrl; 
开关（ctrlName）
 {
 case" Label"：
 ctrl = new Label（）; 
休息; 
 case" TextBox" ;: 
 ctrl = new TextBox（）; 
休息; 
 case" PictureBox"：
 ctrl = new PictureBox（）; 
休息; 
 case" ListView"：
 ctrl = new ListView（）; 
休息; 
 case" ComboBox" ;: 
 ctrl = new ComboBox（）; 
休息; 
 case" Button"：
 ctrl = new Button（）; 
休息; 
 case" CheckBox"：
 ctrl = new CheckBox（）; 
休息; 
 case" MonthCalender" ;: 
 ctrl = new MonthCalendar（）; 
休息; 
 case" DateTimePicker" ;: 
 ctrl = new DateTimePicker（）; 
休息; 
默认值：
程序集controlAsm = Assembly.LoadWithPartialName（partialName）; 
类型controlType = controlAsm.GetType（partialName +"。" + ctrlName）; 
 ctrl =（Control）Activator.CreateInstance（controlType）; 
休息; 
 
} 
返回ctrl; 
 
} 
 catch（exception ex）
 {
 System.Diagnostics.Trace.WriteLine（" create control failed：" + ex.Message）; 
返回新的Control（）; 
} 
} 
 
 public static void SetControlProperties（Control ctrl，Hashtable propertyList）
 {
 PropertyDescriptorCollection properties = TypeDescriptor.GetProperties（ctrl）; 
 
 foreach（属性中的PropertyDescriptor myProperty）
 {
 if（propertyList.Contains（myProperty.Name））
 {
 Object obj = propertyList [myProperty 。名称]; 
尝试
 {
 myProperty.SetValue（ctrl，obj）; 
} 
 catch（Exception ex）
 {
 //什么都不做，只需继续
 System.Diagnostics.Trace.WriteLine（ex.Message）; 
} 
} 
} 
}

然后在按钮中单击：

 private void button9_Click（object sender，EventArgs e）
 {
 tableLayoutPanel1.RowCount ++; 
 for（int column = 0; column< tableLayoutPanel1.ColumnStyles.Count; column ++）
 {
 Control c = this.tableLayoutPanel1.GetControlFromPosition（column，tableLayoutPanel1.RowCount-2）; 
控制ctrl = ControlFactory.CloneCtrl（c）; 
 
 for（int row = 0; row< tableLayoutPanel1.RowStyles.Count; row ++）
 {
 tableLayoutPanel1.Controls.Add（ctrl，column，tableLayoutPanel1.RowCount-1 ）; 
} 
} 
} 

希望这会有所帮助！

最好的问候，

Hi,

I have created a win form application with tablelayout panel.

On click of button i would like to repeat the same above row along with controls and data source but with clear selection.

How to do it?

解决方案

Hi NirajZ,

If you want to repeat the control, you have to clone it first, and as we all know, the controls are all classes so you also have to copy them in depth, please refer to the following clone class:

    public class ControlFactory
    {
        public ControlFactory()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        public static Control CreateControl(string ctrlName, string partialName)
        {
            try
            {
                Control ctrl;
                switch (ctrlName)
                {
                    case "Label":
                        ctrl = new Label();
                        break;
                    case "TextBox":
                        ctrl = new TextBox();
                        break;
                    case "PictureBox":
                        ctrl = new PictureBox();
                        break;
                    case "ListView":
                        ctrl = new ListView();
                        break;
                    case "ComboBox":
                        ctrl = new ComboBox();
                        break;
                    case "Button":
                        ctrl = new Button();
                        break;
                    case "CheckBox":
                        ctrl = new CheckBox();
                        break;
                    case "MonthCalender":
                        ctrl = new MonthCalendar();
                        break;
                    case "DateTimePicker":
                        ctrl = new DateTimePicker();
                        break;
                    default:
                        Assembly controlAsm = Assembly.LoadWithPartialName(partialName);
                        Type controlType = controlAsm.GetType(partialName + "." + ctrlName);

Then in the button click:

        private void button9_Click(object sender, EventArgs e)
        {
            tableLayoutPanel1.RowCount++;
            for (int column = 0; column < tableLayoutPanel1.ColumnStyles.Count; column++)
            {
                Control c = this.tableLayoutPanel1.GetControlFromPosition(column, tableLayoutPanel1.RowCount-2);
                Control ctrl = ControlFactory.CloneCtrl(c);

                for (int row = 0; row < tableLayoutPanel1.RowStyles.Count; row++)
                {
                    tableLayoutPanel1.Controls.Add(ctrl, column, tableLayoutPanel1.RowCount-1);
                }
