[英]Bind a List to Data Grid View which contains Check Box Column
我很难将对象列表绑定到具有复选框列的数据网格视图。
即使我标识TrueValue和FalseValue,这些值也不会显示。
这是我所做的
public class Tree{
public bool Added{get;set;}
public string TaskName{get;set;}
}
形式就是设计师的样子
private System.Windows.Forms.DataGridViewCheckBoxColumn ClmnCheckBox;
private System.Windows.Forms.DataGridViewTextBoxColumn ClmnName;
this.DgvTrees.Location = new System.Drawing.Point(0, 26);
this.DgvTrees.MultiSelect = false;
this.DgvTrees.Name = "DgvNoneTasks";
this.DgvTrees.RowHeadersVisible = false;
this.DgvTrees.SelectionMode =System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect;
this.DgvTrees.Size = new System.Drawing.Size(505, 145);
this.DgvTrees.TabIndex = 27;
this.DgvTrees.CellContentClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.DgvTrees_CellContentClick);
this.DgvTrees.CellValueChanged += new System.Windows.Forms.DataGridViewCellEventHandler(this.DgvTrees_CellValueChanged);
this.ClmnCheckBox.DataPropertyName = "Added";
this.ClmnCheckBox.FalseValue = "false";
this.ClmnCheckBox.HeaderText = "Add/Remove";
this.ClmnCheckBox.Name = "ClmnCheckBox";
this.ClmnCheckBox.TrueValue = "true";
//
// ClmnName
//
this.ClmnName.DataPropertyName = "TaskName";
this.ClmnName.HeaderText = "Task Name";
this.ClmnName.Name = "ClmnName";
this.ClmnName.ReadOnly = true;
这就是我将列表绑定到网格的方式
var tree= new Tree(){
Added=true,
TaskName="task1"
};
ListOfTrees.Add(tree);
DgvTrees.DataSource=ListOfTrees;
现在,超出这一点,我得到了记录,但是未选中该复选框。 如果我手动检查它,它将被检查,但是一旦刷新网格或对其进行排序,检查就消失了。 是什么原因造成的?
我通过听事件“ Row Attached”来解决问题,每次通过排序或过滤将天气添加到行中时,都将复选框设置为对象布尔值
