How to search in Data gridview in C# Windows Form application?

Question

I have a form in which a simple gridview is populated by a table in database having columns like TicketID, Name, Company, Product etc. Now I want to add a search feature so that user could search by customer name or company or TicketID.

How can I do that ? I want to place a combox box, textbox and a simple "search" button above datagrid. When the user selects TicketID for example, enters "1" in textbox and presses "Search", it should refresh datagrid with entry where TicketID = 1.

Now I don't have any idea on how to implement it. Googled for it but found nothing useful. So any help in this regard will be appreciated.

Regards.

Answer 1

You may look into:

BindingSource bs = new BindingSource();
bs.DataSource = dataGridView1.DataSource;
bs.Filter = columnNameToSearch + " like '%" + textBox1.Text + "%'";
dataGridView1.DataSource = bs;

This will show you records containing text from textbox1 in column of your choice. I did exactly what you are asking for:)

Answer 2

Create a Textbox for search input and use the following code on its TextChanged event

private void txtSearch_TextChanged(object sender, EventArgs e)
{
    (dataGridView.DataSource as DataTable).DefaultView.RowFilter = string.Format("TicketID like '{0}%' OR Product like '{0}%' OR Name like '{0}%' OR Product like '{0}%'", txtSearch.Text);
}
