Getting a Parameter Value from a TextBox Control<\/strong><\/h4>\n\n\n\n

In ASP.NET, you can get the value of a parameter from a TextBox control by accessing its Text property. Here’s an example of how to get the value of a parameter from a TextBox control and use it in a SQL query:<\/p>\n\n\n\n

string connectionString = ConfigurationManager.ConnectionStrings[“NorthwindConnectionString”].ConnectionString;<\/p>\n\n\n\n

string query = “SELECT CompanyName, ContactName, ContactTitle, Address, City, Region, PostalCode, Country, Phone, Fax FROM Customers WHERE CustomerID = @CustomerID”;<\/p>\n\n\n\n

using (SqlConnection connection = new SqlConnection(connectionString))<\/p>\n\n\n\n

{<\/p>\n\n\n\n

    SqlCommand command = new SqlCommand(query, connection);<\/p>\n\n\n\n

    command.Parameters.AddWithValue(“@CustomerID”, TextBox1.Text);<\/p>\n\n\n\n

    connection.Open();<\/p>\n\n\n\n

    SqlDataReader reader = command.ExecuteReader();<\/p>\n\n\n\n

    if (reader.Read())<\/p>\n\n\n\n

    {<\/p>\n\n\n\n

        string companyName = reader.GetString(0);<\/p>\n\n\n\n

        string contactName = reader.GetString(1);<\/p>\n\n\n\n

        string contactTitle = reader.GetString(2);<\/p>\n\n\n\n

        string address = reader.GetString(3);<\/p>\n\n\n\n

        string city = reader.GetString(4);<\/p>\n\n\n\n

        string region = reader.IsDBNull(5) ? null : reader.GetString(5);<\/p>\n\n\n\n

        string postalCode = reader.IsDBNull(6) ? null : reader.GetString(6);<\/p>\n\n\n\n

        string country = reader.GetString(7);<\/p>\n\n\n\n

        string phone = reader.GetString(8);<\/p>\n\n\n\n

        string fax = reader.IsDBNull(9) ? null : reader.GetString(9);<\/p>\n\n\n\n

        \/\/ Do something with the retrieved data<\/p>\n\n\n\n

    }<\/p>\n\n\n\n

    reader.Close();<\/p>\n\n\n\n

}<\/p>\n\n\n\n

In this example, the Text property of the TextBox control is accessed and passed as the value of the “@CustomerID” parameter using the Parameters.AddWithValue method of the SqlCommand object. This allows the user to enter a value into the TextBox control, which is then used as a parameter in the SQL query.<\/p>\n\n\n\n
