Procedure or function ... has too many arguments specified.

[speranza]

i have multiple checkboxes on my form.i am trying to add them with stored procedure but it gives me Procedure or function konut_ekle has too many arguments specified

protected void Button1_Click1(object sender, EventArgs e)
    {

        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString);
        SqlCommand cmd;
        con.Open();
        string cmdstr = "konut_ekle";
        cmd = new SqlCommand(cmdstr, con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@kategori", TextBox1.Text);
        cmd.Parameters.AddWithValue("@tip", TextBox2.Text);
        cmd.Parameters.AddWithValue("@il", TextBox3.Text);
        cmd.Parameters.AddWithValue("@ilce", TextBox4.Text);
        cmd.Parameters.AddWithValue("@semt", TextBox5.Text);
        cmd.Parameters.AddWithValue("@fiyat", TextBox7.Text);
        for (int i = 0; i < CheckBoxList1.Items.Count; i++)
        {
            if (CheckBoxList1.Items[i].Selected)
            {
                cmd.Parameters.AddWithValue("@ozellik", CheckBoxList1.Items[i].Value);
            }
        }
        cmd.ExecuteNonQuery();
        cmd.Dispose();
        con.Close();
    }

ALTER PROCEDURE konut_ekle
@kategori varchar(50),
@tip varchar(50),
@il varchar(50),
@ilce varchar(50),

Here is your problem. Loop adds more than parameters originally a stored procedure has.

for (int i = 0; i < CheckBoxList1.Items.Count; i++)
        {
            if (CheckBoxList1.Items[i].Selected)
            {
                cmd.Parameters.AddWithValue("@ozellik", CheckBoxList1.Items[i].Value);
            }
        }

You should concatenate the checkboxlist item's values and then assign a concatenated string as parameter value.

protected void Button1_Click1(object sender, EventArgs e)
    {
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString);
        SqlCommand cmd;
        con.Open();
        string cmdstr = "konut_ekle";
        cmd = new SqlCommand(cmdstr, con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@kategori", TextBox1.Text);
        cmd.Parameters.AddWithValue("@tip", TextBox2.Text);
        cmd.Parameters.AddWithValue("@il", TextBox3.Text);
        cmd.Parameters.AddWithValue("@ilce", TextBox4.Text);
        cmd.Parameters.AddWithValue("@semt", TextBox5.Text);
        cmd.Parameters.AddWithValue("@fiyat", TextBox7.Text);

       // String for concatenate.
        String s="";
        for (int i = 0; i < CheckBoxList1.Items.Count; i++)
        {
            if (CheckBoxList1.Items[i].Selected)
            {
                s=s + "  " + CheckBoxList1.Items[i].Value;
            }
        }
    cmd.Parameters.AddWithValue("@ozellik", s);
        cmd.ExecuteNonQuery();
        cmd.Dispose();
        con.Close();
    }

your connection string is wrong...

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString

instead use....

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].toString());
