我試圖將默認值添加到已填充數據源的組合框中。檢查圖像下方:C# - 爲填充數據綁定的組合框添加值?
值從Oracle數據庫自動添加。現在我需要做的是再添加一個默認值,它將代表所有類別。
這裏是一個設計師代碼:
this.comboBox2.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.vRSTEPROBLEMABindingSource, "NAZIV", true));
this.comboBox2.DataSource = this.vRSTEPROBLEMABindingSource1;
this.comboBox2.DisplayMember = "NAZIV";
this.comboBox2.FormattingEnabled = true;
this.comboBox2.Location = new System.Drawing.Point(89, 51);
this.comboBox2.Name = "comboBox2";
this.comboBox2.Size = new System.Drawing.Size(173, 21);
this.comboBox2.TabIndex = 4;
this.comboBox2.Text = "Svi";
this.comboBox2.ValueMember = "NAZIV";
在將數據源設置爲綁定源之前,您需要添加默認值。 – msmolcic
