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.

Did you bind their selectedindexchanged event to the same event? Also it would be helpful if you can provide some code

I didn't write any code in selectedindexchanged event. only bind these controls with same datasource

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

this.cmbParent.DataSource= dtAgencies;
this.cmbParent.DisplayMember = "agencyID";
this.cmbParent.ValueMember = "conString";

}

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

Solution 3

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

C#

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

Checklistbox selected index change event...

C#

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

Happy Coding!
:)

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";
              
}
