Question

I am trying to use the wildcard query to display rows in a gridview but it is not up to the mark…

protected void Button1_Click(object sender, EventArgs e)
{
    SqlCommand com = new SqlCommand("select * from Alphabates where Word 
                     like'"+TextBox1.Text+"'", new SqlConnection("data source=
                     USER\\SQLEXPRESS;initial catalog=vicky;integrated 
                     security=true"));

    try
    {
        com.Connection.Open();
        GridView1.DataSource = com.ExecuteReader();
        GridView1.DataBind();
        com.Connection.Close();
        com.Connection.Dispose();
    }
    catch (SqlException ex)
    {
        Label1.Text = ex.Message;
    }
}

try this:

Change your query to add % around the text box value

wildcard search requires a % sign to get the desired result, other wise it would be same as using an equal to(=) sign

"select * from Alphabates where Word like %'"+TextBox1.Text+"%'"

As per your comment if you want rows starting with given word then:

"select * from Alphabates where Word like '"+TextBox1.Text+"%'"

Ex:

select * from Alphabates where Word like 'Some value'

is same as

select * from Alphabates where Word ='Some value'

so you should change it to

select * from Alphabates where Word like '%Some value%'
