C# - How to Removing Not Visible Rows From DataGridView

Hello everyone.

My environment: Windows 7 Ultimate, C#, VS2010 Ultimate, WinForm.
Target: Windows from XP to 7.
My application adds a line to a DataGridView in 1 minute intervals.
My DataGridView has 15 rows and 8 columns.
In the 16th to add data; first the DataGridView will roll up, insert a blank line and then add the data in this new line.
My question: The rolled up line of DataGridView is still in memory?
If yes, how to remove this line of the DataGridView, keeping in DataGridView memory only the data that are visible?

Thanks in advance, ocaccy

Hi,

Can you tell us how do you bind the data/new line to DataGridView?

Hi,

private void tmr_GET_Tick(object sender,EventArgs e)
	{
	string[] row= { a_i_ler[i_C_AR, 0], a_i_ler[i_C_AR, 1], a_i_ler[i_C_AR, 2], a_i_ler[i_C_AR, 3], a_i_ler[i_C_AR, 4], a_i_ler[i_C_AR, 5], a_i_ler[i_C_AR, 6], a_i_ler[i_C_AR, 7]};
	dataGridView1.Rows.Add(row);
	}

Open in new window

Thank you,

Hi,

I don't know the internals of how DataGridView works but as and when the row has been added, the blank like will not exist any more. You can check this by taking a row count.

There is no need to explicitly remove the blank new line. The control itself will manage these changes.

Hi, Then those rows that are not seen and have no scrollbar have been deleted freeing memory?
