Winform控件操作

Posted 2020-11-24 zhixiaoxiao

对于控件赋值，刚接触客户端(WPF)的时候是一个控件一个控件的传值 ，如：this.xxx.Text ="123",后来，觉得这样太麻烦了，就用循环控件进行绑定值以及得到json格式的值(https://www.cnblogs.com/zhixiaoxiao/p/11897143.html),太好用了。妈妈再也不用担心我因为给N个控件赋值而累死了。

下面是我第一次接触Winform的笔记，笔记粗糙， 没有封装成一个完整的类，后面项目中会整理，记录下来:

循环绑定的代码如下:

 foreach (Control item in this.panel.Controls)
            {
                if (item is TextBox)
                {
                    var tex = item as TextBox;
                    tex.Text = t.Textb;
                }
                if (item is CheckBox)
                {
                    var ch = item as CheckBox;
                    ch.Checked = t.Checkb;
                }
                if (item is DataGridView)
                {
                    var dg = item as DataGridView;
                    dg.DataSource = tests;
                }
                if (item is ListBox)
                {
                    var lis = item as ListBox;
                    lis.DisplayMember = "Textb";
                    lis.ValueMember = "Checkb";
                    lis.DataSource = tests;
                }
            }

　多控件循环取值，放到Json中，代码如下:

Dictionary<string, object> keyValues = new Dictionary<string, object>();
            foreach (Control item in this.panel.Controls)
            {
                if (item is TextBox)
                {
                    var tex = item as TextBox;
                    keyValues.Add(tex.Name, tex.Text);
                }
                if (item is CheckBox)
                {
                    var ch = item as CheckBox;
                    keyValues.Add(ch.Name, ch.Checked);
                }
                if (item is DataGridView)
                {
                    var dg = item as DataGridView;
                    keyValues.Add(dg.Name, (dg.CurrentRow.DataBoundItem as Test).Textb);
                }
                if (item is ListBox)
                {
                    //var lis = item as ListBox;
                    //lis.DisplayMember = "Textb";
                    //lis.ValueMember = "Checkb";

                }
            }
            string jsonStr = JsonConvert.SerializeObject(keyValues);
            MessageBox.Show(jsonStr);
