Hi, I am getting this error<<Procedure or function 'SearchTestName' expects parameter '@TestName', which was not supplied.>>
when trying to search value in my table using a stored procedure and c# code.

T-SQL:

SQL

CREATE PROC [dbo].[SearchTestName]
@TestName nvarchar(50)
AS
  BEGIN
     SELECT * FROM Test where (TestName like '%'+ @TestName +'%');
  END

c# code:

<pre> protected void Seach_Onclick(object sender, EventArgs e)
        {
           sqlcon.Close();
            sqlcon.Open();
            SqlDataAdapter adapter = new SqlDataAdapter();
            DataTable ds = new DataTable();
           
            try
            {
                SqlCommand sqlcom = new SqlCommand("[SearchTestName]", sqlcon);
                sqlcom.Parameters.Add("@TestName", SqlDbType.NVarChar, 50).Value = txtSearchTestName.Text.Trim();
                adapter.SelectCommand = sqlcom;
                adapter.Fill(ds);
                labelSearch.Text = "Data Found!";
                Response.Redirect("ConnectionString.aspx", true);
                 
           
            }
            catch (Exception ex)
            {
                labelSearch.Text = ex.ToString();
            }
             
        }

What I am trying to do is to enter a value in a textbox then when hit on the button Search,I must get the data from the table test.
Please can someone help fixing this

That means you are not sending the parameter to your stored procedure. You need to create an SQLParameter and give it a value and name. See my solution below. You are adding a parameter as if you were doing a query, not using a stored procedure.

Besides I believe parameters.add is deprecated. See if you can try parameters.AddWithValue is preferred (especially if you are using Visual Studio 2012).

I have changed like that but I am getting this error:Procedure or function 'SearchTestName' expects parameter '@TestName', which was not supplied.
This how I have changed:
c# code:
SqlDataAdapter adapter = new SqlDataAdapter();
DataTable ds = new DataTable();

try
{
SqlCommand sqlcom = new SqlCommand("[SearchTestName]", sqlcon);
sqlcom.Parameters.AddWithValue("@TestName", 50).Value = txtSearchTestName.Text.Trim();
adapter.SelectCommand = sqlcom;
adapter.Fill(ds);
labelSearch.Text = "Data Found!";
Response.Redirect("ConnectionString.aspx", true);

}
catch (Exception ex)
{
labelSearch.Text = ex.ToString();
}

Do something like this:

SqlParameter dataParameter = new SqlParameter();
dataParameter.Value = 50;
dataParameter.ParameterName = "@TestName";

SqlCommand cmd = new SqlCommand(("[SearchTestName]", sqlcon);
SqlDataReader reader = null;

cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(dataParameter);

conn.Open();
reader = cmd.ExecuteReader();

Hello,

Replace your with this

C#

SqlDataAdapter adapter = new SqlDataAdapter();
            DataTable ds = new DataTable();
            SqlCommand sqlcom = new SqlCommand("selectdata", sqlcon);
            sqlcom.CommandType = CommandType.StoredProcedure;
            sqlcom.Parameters.Add(new SqlParameter("name", "Juhi Paunikar"));
            ds.Load(sqlcom.ExecuteReader());
            sqlcon.Close();

you are missed the line command type -4th line in my code.

Procedure or function 'SearchTestName' expects parameter '@TestName', which was not supplied.
