[RESOLVED] DataGridView RowFilter is one keyPress behind

[Netrag]

Hi all,

Im working with DataGridView and trying to apply TextBox(keypress) dynamic filter.
Im using DefaultView.RowFilter with proper parameters. Filter works, but there is problem with "updating" table.

Lets have a search word: bicycle
When I type first letter into textbox "b" , nothing happends. When I type second letter "i", filter is set to "b" and shows appropriate results for "b".

Code that handles textchange

// Assignment
tbox_search.KeyDown += new System.Windows.Forms.KeyEventHandler(this.dynamicFilter_KeyPress);

// Keypress function
public void dynamicFilter_KeyPress(Object sender, KeyEventArgs e)
        {
            Control ctr = (Control)sender;

            (dtgview.DataSource as DataTable).DefaultView.RowFilter = string.Format("{0} LIKE '%{1}%'", dtgview.Columns[ctr.TabIndex].Name, ctr.Text);
        }

Am I missing something? Thank You for any help!

Try using the TextChanged event rather than keydown.

tbox_search.TextChanged += new EventHandler(tbox_search_TextChanged);
 
void tbox_search_TextChanged(object sender, EventArgs e)
{
            Control ctr = (Control)sender;
            (dtgview.DataSource as DataTable).DefaultView.RowFilter = string.Format("{0} LIKE '%{1}%'", dtgview.Columns[ctr.TabIndex].Name, ctr.Text);
}
