US
when the form is display

i want to display 4th value (India) is selected by default

what is the code

推荐答案

试试这个：



combobx1.Text =印度



但如果您有数据网格视图则不同：

通过代码创建它：

try this :

combobx1.Text = "India"

but if you have a datagridview it's different :
to create it by code :

string[] str = {"Chennai","Bangalore","Trivandrum","India","US"};
 DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn();
                cmb.HeaderText = "Headertext";
                cmb.Name = "name";
                cmb.MaxDropDownItems =str.Count() ;
                foreach (String o in str)
                {
                   cmb.Items.Add(o);
                }
                dataGridView.Columns.Add(cmb);

然后更改你应该使用的文字：

then to change the text you should use :

for (int i = 0; i < dataGridView.Rows.Count - 1; i++)
             {
                             dataGridView.Rows[i].Cells[where the combobx located].Value = "India";
             }

尝试comboBoxLocation.SelectedIndex = 3

Try comboBoxLocation.SelectedIndex=3

在Form加载事件上写下此代码

Write this code on your Form load event

combobox1.SelectedIndex=combobox1.FindStringExact("India");
