我對自動排序的datagridview有問題。 當我點擊列標題一次,它的值被排序,但三角形標記保持不變,所以它指向錯誤的方向。 第二次點擊時,它的三角形發生了變化(它現在將指向不同的方向,但在與datagridview中的值進行比較時是正確的) 然後,排序過程重複 - 因此,如果我想對列進行排序,則必須單擊標題兩次:首先要更改方向標記/字形,然後再排序值。爲什麼datagridview需要雙擊來對列進行排序

我並不認爲這很重要,但是對於這個DGV,我使用了BindingList作爲數據源。

設計師代碼:

 // 
     // dgv 
     // 
     this.dgv.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; 
     this.dgv.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] { 
     this.monthColumn, 
     this.colorColumn}); 
     this.dgv.Location = new System.Drawing.Point(22, 127); 
     this.dgv.Name = "dgv"; 
     this.dgv.Size = new System.Drawing.Size(468, 164); 
     this.dgv.TabIndex = 0; 
     this.dgv.CellBeginEdit += new System.Windows.Forms.DataGridViewCellCancelEventHandler(this.dgv_CellBeginEdit); 
     this.dgv.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgv_CellClick); 
     this.dgv.CellEndEdit += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgv_CellEndEdit); 
     this.dgv.RowsAdded += new System.Windows.Forms.DataGridViewRowsAddedEventHandler(this.dgv_RowsAdded); 
     // 
     // monthColumn 
     // 
     this.monthColumn.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.AllCells; 
     dataGridViewCellStyle3.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter; 
     this.monthColumn.DefaultCellStyle = dataGridViewCellStyle3; 
     this.monthColumn.HeaderText = "Miesiące"; 
     this.monthColumn.Name = "monthColumn"; 
     this.colorColumn.ValueType = typeof(int); 
     this.monthColumn.Width = 72; 
     // 
     // colorColumn 
     // 
     this.colorColumn.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.Fill; 
     dataGridViewCellStyle4.Alignment = System.Windows.Forms.DataGridViewContentAlignment.MiddleCenter; 
     this.colorColumn.DefaultCellStyle = dataGridViewCellStyle4; 
     this.colorColumn.HeaderText = "Barwa"; 
     this.colorColumn.Name = "colorColumn"; 
     this.colorColumn.SortMode = System.Windows.Forms.DataGridViewColumnSortMode.NotSortable; 
     this.colorColumn.ValueType = typeof(System.Drawing.Color); 

綁定過程:

 dgv.AutoGenerateColumns = false; 
     monthColumn.DataPropertyName = "Months"; 
     colorColumn.DataPropertyName = "Color"; 
     colorColumn.ReadOnly = false; 
     dgv.DataSource = bcolors;//BindingList 
     dgv.Sort(monthColumn, ListSortDirection.Ascending); 

事件方法用於應用的backgroundColor行和禁止編輯colorColumn(只讀不工作,但是這不是問題的關鍵?這裏)

你可以嘗試改變列的sortmode?

改變這一點:

this.colorColumn.SortMode = System.Windows.Forms.DataGridViewColumnSortMode.NotSortable; 

到這一點:

this.colorColumn.SortMode = System.Windows.Forms.DataGridViewColumnSortMode.Automatic; 
+0

這並不在我的情況下改變什麼,我也真的不想此列可排序,這就是爲什麼我用NotSortable設置。 –
