Windows中的ComboBox和checkboxList [英] ComboBox and checkboxList in windows

问题描述

我在windows窗体中使用了combobox和checkboxlist，它的值相同。我在改变这些控件的选定值时面临一个问题。如果我在复选框列表中更改选定的值，则组合框选择的值也会在复选框列表中相同更改，反之亦然。我需要限制这个。请帮助我。

I am using combobox and checkboxlist in my windows form and its values are same. I am facing one issue while change the selected value of these controls. If I changing selected value in the checkboxlist, then the combobox selected value is also changed as the same in the checkboxlist and viceversa. I need to restrict this. Please help me.

推荐答案

尝试下面的代码：

Try below code:

DataTable dtAgencies = GetAgencies();
if (dtAgencies.Rows.Count > 0)
{
      this.chkListChild.DataSource = dtAgencies;
      this.chkListChild.DisplayMember = "agencyID";
      this.chkListChild.ValueMember = "conString";
      
      DataTable dtCopy = dtAgencies.Copy();             
      this.cmbParent.DataSource= dtCopy;
      this.cmbParent.DisplayMember = "agencyID";
      this.cmbParent.ValueMember = "conString";
              
}

希望它有所帮助！

Hope it helps!

使用dtAgencies .Copy（）是个好主意。 chkListChild和cmbParent应绑定不同

Using a dtAgencies.Copy() is a good idea. chkListChild and cmbParent should be bound different

你应该添加额外的if条件来控制它...

组合框选择索引更改事件...

you should add extra if condition to control this...
combobox selected index change event...

if (YourComboboxName.Focused == true)
{
 //checkbox selection-index code here 
}

Checklistbox选择的索引更改事件......

Checklistbox selected index change event...

if (YourChecklistboxName.Focused == true)
{
 //Combobox selection-index code here 
}
