跟踪栏指向checkedlistbox中的相同项目 [英] Trackbar point to equal items in a checkedlistbox

问题描述

我有一个checklistbox和一个trackbar，我希望跟踪器点数根据checklistbox中的项目数量而变化。即



如果核对表有5个项目，我希望轨迹栏也只有5个点（最高点）。





这是可能的，我试图通过列表框和清单箱来实现这一点，但两者都无效.... br $> b $ b





trackBar1.Maximum = checkedlistbox1.Items.Count;



我尝试过：



trackbar1.Value = checkedlistboox.Items.Count.ToString（）;

I have a checklistbox and a trackbar, I want the trackers points to change according to the amount of items are in the checklistbox. i.e.

If the checklistbox has 5 items, I want the trackbar to only have 5 points (maximum point) also.


Is this possible, I've tried to carry this out with a listbox and a checklistbox but neither works....



trackBar1.Maximum = checkedlistbox1.Items.Count;

What I have tried:

trackbar1.Value = checkedlistboox.Items.Count.ToString();

推荐答案

您显示的代码有拼写错误，并且（非法）尝试将字符串指定为TrackBar值;这有效：

The code you show has spelling errors, and an (illegal) attempt to assign a string as a TrackBar value; this works:

trackBar1.Maximum = checkedListBox1.Items.Count;
trackBar1.Value = trackBar1.Maximum;

但是......我猜你想要对CheckedListBox中的项目数进行任何更改以反映在TrackBar中...为什么呢你会拥有一个TrackBar吗？很可能，但可能的是，你不知何故想要改变TrackBar值来控制CheckedListBox中的项目数。



为什么不澄清你在这做什么？

But ... I'm guessing you want any change to the number of items in the CheckedListBox to be reflected in the TrackBar ... why else would you have a TrackBar ? Much less likely, but possible, is that you somehow want a change in the TrackBar value to control the number of items in the CheckedListBox.

Why don't you clarify what you are doing here ?
