如何使用按钮滚动FlowLayout面板 [英] How to Scroll a FlowLayout Panel with Using Buttons

问题描述

伙计们，

如何使用两个按钮滚动FlowLayout面板。我的FlowLayout面板包含带有图片框的UserControls。我想用两个按钮向上滚动它们&下。我就是这样，

 私人  void  BtnProdUp_Click（ object  sender，EventArgs e）
 {
  this  .FlowProducts .VerticalScroll.Value =  this  .FlowProducts.VerticalScroll.LargeChange  -   1 ; 
 FlowProducts.PerformLayout（）; 
 
} 
 
  private   void  btnProdDown_Click（< span class =code-keyword> object  sender，EventArgs e）
 {
 
  this  .FlowProducts。 VerticalScroll.Value =  this  .FlowProducts.VerticalScroll.LargeChange +  1 ; 
 FlowProducts.PerformLayout（）; 
 
} 

我不想要FlowLayout Panel中的滚动条。我的COED不能正常工作请帮助我非常紧急。

解决方案

1。使用设置插入FlowLayoutControl：



Dock = DockStyle.None;

AutoScroll = false;

AutoSize = true;

WrapContents = true;

FlowDirection = TopDown



2.进入面板大小按要求

  private   const   int  VerticalStep =  40 ; 
 
  private   void  BtnProdUp_Click（ object  sender，EventArgs e）
 {
 FlowProducts.Top  -  = VerticalStep; 
} 
 
  private   void  btnProdDown_Click（ object  sender，EventArgs e）
 {
 FlowProducts.Top + = VerticalStep; 
} 

我想考虑的另一个选择是通过鼠标点击拖动使FlowLayoutPanel移动到它位于的面板中......但是，这需要......时间。

I dont want Scroll Bar in FlowLayout Panel. My COde Dosen't Work Properly Please Help me Its Very Urgent.

解决方案

1. insert the FlowLayoutControl with settings:

Dock = DockStyle.None;
AutoScroll = false;
AutoSize = true;
WrapContents = true;
FlowDirection = TopDown

2. into a Panel sized as required

private const int VerticalStep = 40;

private void BtnProdUp_Click(object sender, EventArgs e)
{
    FlowProducts.Top -= VerticalStep ;
}

private void btnProdDown_Click(object sender, EventArgs e)
{
    FlowProducts.Top += VerticalStep ;
}

An alternative I would consider would be to make the FlowLayoutPanel movable by mouse click-drag in the Panel it is sited within ... but, that would take ... time.
