comboBox doesn't work properly

Question

Hello :) I have a datagridview in form 1 and in form 2 a comboBox. I want to select an item from the comboBox depending on a cell from dgv. Here's the code

SqlConnection conn = new SqlConnection();

conn.ConnectionString = "..";

conn.Open();

Acasa main = (Acasa)Application.OpenForms["Acasa"];

DataGridView dgv = main.categdaGridView;

int i = dgv.CurrentRow.Index;

textBox1.Text = dgv.Rows[i].Cells[1].Value.ToString();

textBox3.Text = dgv.Rows[i].Cells[3].Value.ToString();

comboBox1.SelectedItem = dgv.Rows[i].Cells[2].Value.ToString();

conn.Close();

but the comboBox doesn't select nothing :| if i do comboBox1.SelectedItem="discount" it works, and i checked dgv.Rows[i].Cells[2].Value.ToString(); has the same value(discount). Does anybody know what could cause it? Thank u very much.

I don't know anyting about sqlConnections but I've tested it on Private void dgv_RowHeaderMouseClick(object sender DataGridViewCellMouseEventArgs e) { int i= dgv.CurrentRow.Index; comboBox1.SelectedItem = dgv.Rows[I].Cells[1].Value.ToString(); } Or the same code in the button1_Click(...) If I use the first code it change everytime click on a new row

Does: comboBox1.SelectedText = adaos; select adaos? If it doesn't then possibly the value in the comboBox has some whitespace at the end?

Try using comboBox1.SelectedItem instead

I've used SelectedText and it's working but if i select a different row it shows the same value. For exemple: B1 discount 10 B2 adaos 5 B3 discount 10 if i select the first row the cb shows discount but if then i select the second row..doesn't show adaos it's still discount :(

Assuming there are no differences in capitalization the problem might be caused by the strings being treated as different objects even though they contain the same characters. Try setting the comboBox1.SelectedText property instead of the SelectedItem property.

...select an item from the comboBox depending on a cell from dgv... Do you mean that for example if a user type discount in cell[x] the word discount must be selected in the combobox?
