將滾動條添加到包含縮略圖圖像的Groupbox

Question

這是我的Designer.cs代碼。

this.gbFacets.Location = new System.Drawing.Point(590, 69); 
this.gbFacets.Name = "gbFacets"; 
this.gbFacets.Size = new System.Drawing.Size(255, 355); 
this.gbFacets.TabIndex = 7; 
this.gbFacets.TabStop = false; 
this.gbFacets.Text = "Facets Found"; 
this.gbFacets.Enter += new System.EventHandler(this.gbFacets_Enter); 

這裏是我的Formmain代碼

private void AddFacetsToPictureBoxes(List<PictureBox> pictureBoxes) 
{ 
    foreach (var pic in pictureBoxes) 
     this.gbFacets.Controls.Add(pic); 
} 

我得到的圖片添加到組合框中，但如果沒有圖片增加的話，那隻能說明一些照片。所以請告訴我如何使這個groupbox滾動查看所有圖片。

Answer 1

由於groupbox沒有可滾動屬性，因此請將圖像添加到面板，並設置可滾動屬性。

然後讓面板填滿組框。

編輯：這樣的事情

private void AddPicturesToGroupBox(List<PictureBox> pictureBoxes) 
{ 
    Panel myPanel = new Panel(); 
    myPanel.Dockstyle = Dockstyle.Fill; 
    myPanel.AutoScroll = true; //this allows the panel to display scrollbars when it needs to 

    foreach (var pic in pictureBoxes) 
    { 
     myPanel.Controls.Add(pic); //put your pictures onto the panel 
    } 

    this.gbFacets.Controls.Clear(); 
    this.gbFacets.Controls.Add(myPanel); //put your panel inside the Groupbox 
}
