convert combobox.selectedItem to int32 c#

My conversion code is as follows: 

para = Int32.Parse(cmbCompany.SelectedItem.ToString());

The data binding code for my combo-box is as so:

string query = "select CompanyID as ID, CompanyName as Name from tblCompany";
comb.ValueMember = "ID";
comb.DisplayMember = "Name";
comb.DataSource = ds.Tables[0];

When I run the above code, I get a conversion error:

How do I solve this problem?

Use comboBox1.SelectedValue

 Int32.Parse(comboBox1.SelectedValue.ToString());

You can use Int32.TryParse if you expect empty value for combo

int number;
bool result = Int32.TryParse(comboBox1.SelectedValue.ToString(), out number);
if (result)
{
     //Your code
}

Another technique is to use Convert.ToInt32

Convert.ToInt32(comboBox1.SelectedValue);
