[英]Bind a List to Data Grid View which contains Check Box Column
我很難將對象列表綁定到具有復選框列的數據網格視圖。
即使我標識TrueValue和FalseValue,這些值也不會顯示。
這是我所做的
public class Tree{
public bool Added{get;set;}
public string TaskName{get;set;}
}
形式就是設計師的樣子
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;
這就是我將列表綁定到網格的方式
var tree= new Tree(){
Added=true,
TaskName="task1"
};
ListOfTrees.Add(tree);
DgvTrees.DataSource=ListOfTrees;
現在,超出這一點,我得到了記錄,但是未選中該復選框。 如果我手動檢查它,它將被檢查,但是一旦刷新網格或對其進行排序,檢查就消失了。 是什么原因造成的?
我通過聽事件“ Row Attached”來解決問題,每次通過排序或過濾將天氣添加到行中時,都將復選框設置為對象布爾值
