样本数据。

Hi,

I am using datagridview.

i just want to update the combobox cell value. i cell value should update based on my condition.

But, the problem is, combobox value displaying which is last executed value only always. the remining condition is updating the cell.

what is the problem in my code.

sample data.

EMPNO	STATUS (Dropdown)
101	1-EXCELLENT 2-MODERATE
102	1-EXCELLENT 2-MODERATE 3-GOOD 4-AVERAGE
103	1-EXCELLENT 2-MODERATE 3-GOOD 4-AVERAGE
104	1-EXCELLENT 2-MODERATE
105	1-EXCELLENT 2-MODERATE 3-GOOD 4-AVERAGE
106	1-EXCELLENT 2-MODERATE 3-GOOD 4-AVERAGE

我试过的：

What I have tried:

List<string> Emplist = new List<string>(); 
foreach (DataRow row in dt.Rows)
 {
         Grid1.Rows.Add();
         Grid1[0, cnt].Value = row["EmpNO"].ToString();
         Grid1.UpdateCellValue(0, cnt);
         DataGridViewComboBoxCell cbobox = (DataGridViewComboBoxCell)Grid1[1, cnt];
	 
	 if (cbobox.Items.Count == 0)
         {
		// Conditions
	   
	 if ((Mark1 != 0) && (SUB == "H1"))
         {
             Emplist.Clear();
             Emplist.Add("1-EXCELLENT");
             Emplist.Add("2-MODERATE");
             cbobox.DataSource = Emplist;
             Grid1.UpdateCellValue(3, cnt);

         }
	 else if ((Mark2 != 0) && (SUB2 == "H2"))
         {
             Emplist.Clear();
             Emplist.Add("1-EXCELLENT");
             Emplist.Add("2-MODERATE");
	     Emplist.Add("3-GOOD");
             Emplist.Add("3-AVERAGE");
             cbobox.DataSource = Emplist;
             Grid1.UpdateCellValue(3, cnt);

         }


	 }

	 Grid1.UpdateCellValue(1,cnt);
         Grid1.Refresh();
         cnt++;

  
 }

推荐答案

Thanks.

i tried one more ideas.

I have added different list item to map the combo box cell. it's also working.

Example

List<string> Emplist1 = new List<string>(); 

List<string> Emplist2 = new List<string>(); 

foreach (DataRow row in dt.Rows)
 {
         Grid1.Rows.Add();
         Grid1[0, cnt].Value = row["EmpNO"].ToString();
         Grid1.UpdateCellValue(0, cnt);
         DataGridViewComboBoxCell cbobox = (DataGridViewComboBoxCell)Grid1[1, cnt];
       
       if (cbobox.Items.Count == 0)
         {
            // Conditions
         
       if ((Mark1 != 0) && (SUB == "H1"))
         {
             Emplist.Clear();
             Emplist.Add("1-EXCELLENT");
             Emplist.Add("2-MODERATE");
             cbobox.DataSource = Emplist1;
             Grid1.UpdateCellValue(3, cnt);

         }
       else if ((Mark2 != 0) && (SUB2 == "H2"))
         {
             Emplist.Clear();
             Emplist.Add("1-EXCELLENT");
             Emplist.Add("2-MODERATE");
           Emplist.Add("3-GOOD");
             Emplist.Add("3-AVERAGE");
             cbobox.DataSource = Emplist2;
             Grid1.UpdateCellValue(3, cnt);

         }


       }

       Grid1.UpdateCellValue(1,cnt);
         Grid1.Refresh();
         cnt++;

  
 }


This is also working and simple
