在gridView上搜索什么都不做

Question

I have a gridVIew which has a datasource of a table in Access database.

I want to add search functionality on this gridview. I added a textBox and search button. My Code is

protected void btnSearchService_Click(object sender, EventArgs e)
{
    string SearchField = TextBox1.Text;
    string searchSQL = "SELECT * FROM LocalService WHERE ServiceName LIKE '%" + SearchField + "%'";

    SqlDataSource1.UpdateCommand = searchSQL;
    SqlDataSource1.Update();
}

But in browser when I click Search button, I see nothing happens. DO I have to add code on page load or somewhere?

Answer 1

It worked. I have replaced following lines

SqlDataSource1.UpdateCommand = searchSQL;
SqlDataSource1.Update();

with these lines

SqlDataSource1.SelectCommand = searchSQL;
GridView1.DataBind();
