I want to focus on cell which contains pressed characters.

Assume datagridview which contains two column Name and Address.
Now in Name column there is lot of records Like Nims, john, kan, rocks, rita, etc...

Now if I am entering character 'K','A','N' then cell will be focus on kan.

I have google for this but I get solution as below code which didn't satisfied my question.

Because it is focus cell which contains pressed character as starting character of cell value.

Thanks in advance.

What I have tried:

private void dataGridView1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (Char.IsLetter(e.KeyChar))
    {
        for (int i = 0; i < (dataGridView1.Rows.Count); i++)
        {
            if (dataGridView1.Rows[i].Cells["Name"].Value.ToString().StartsWith(e.KeyChar.ToString(), true, CultureInfo.InvariantCulture))
            {
                dataGridView1.Rows[i].Cells[0].Selected = true;
                return; // stop looping
            }
        }
    }
}

Another option would be to use LINQ wildcard search, here is an example:

Solution 1

You can define a public variable to hold the typed characters and use that in your dataGridView1_KeyPress(). For KeyCodes see: Keys Enumeration (System.Windows.Forms)[^]

C#

public string typedChars = string.Empty;

private void dataGridView1_KeyPress(object sender, KeyPressEventArgs e)
{
    if(e.KeyCode == Keys.Left || e.KeyCode == Keys.Right || e.KeyCode == Keys.Up || e.KeyCode == Keys.Down)
    {
        typedChars = string.Empty;
        return;
    }

    if (Char.IsLetter(e.KeyChar))
    {
        typedChars += e.KeyChar.ToString();

        for (int i = 0; i < (dataGridView1.Rows.Count); i++)
        {
            if (dataGridView1.Rows[i].Cells["Name"].Value.ToString().StartsWith(typedChars, true, CultureInfo.InvariantCulture))
            {
                dataGridView1.Rows[i].Cells[0].Selected = true;
                return; // stop looping
            }
        }
    }
}

Thanks RickZeeland,
I want to reset it on when user press 'UP', 'DOWN', 'LEFT', 'RIGHT' arrow key.
So what should to do?

I updated the solution to reset the variable. Another crazy idea would be to reset the variable after a period of x seconds of no keyboard activity.

Thanks Bro,
Now its all clear.
I have done this before you comment, but I have done with by creating individual dataGridView1_KeyDown method.
By the way it has solved now.
Thanks again.

I m Trying your this code public string typedChars = string.Empty; private void dataGridView1_KeyPress(object sender, KeyPressEventArgs e) { if(e.KeyCode == Keys.Left || e.KeyCode == Keys.Right || e.KeyCode == Keys.Up || e.KeyCode == Keys.Down) { typedChars = string.Empty; return; } if (Char.IsLetter(e.KeyChar)) { typedChars += e.KeyChar.ToString(); for (int i = 0; i < (dataGridView1.Rows.Count); i++) { if (dataGridView1.Rows[i].Cells["Name"].Value.ToString().StartsWith(typedChars, true, CultureInfo.InvariantCulture)) { dataGridView1.Rows[i].Cells[0].Selected = true; return; // stop looping } } } }

but when i excute else part get error or i comment else part so if i type another value which is not exist ge null exception error
