Hello and Happy New Year!

I have a database with a few records. I am using SQL CE. What i would like to be able to do is well you run the application, all the rows in the grid view should be hidden. I dont want the rows to be deleted.

Then when you click on a button, i want all the rows to be visible in the gridview. Is this possible?

I tried to do it myself but i kept getting an error message:

Quote

Row associated with the currency manager's position cannot be made invisible.

  
private void MakeInvisible()
		{
			foreach (DataGridViewRow row in AnimalDataGridView.Rows)
			{
				row.Visible = false;
			}
		}

I have written a method that unhides the rows which is called MakeVisible by using the code above but changing the Visible property to "true".

Could anyone advise how I could go about solving this please?

Thanks in advance.

bool rowsVisible = false;

private void btnHideRows_Click(object sender, EventArgs e)
{
	foreach (DataGridViewRow row in dgvSongs.Rows)
	{
		row.Visible = rowsVisible;
	}

	rowsVisible = !rowsVisible;
}

Hope this helps.

Hi what I have done is put the code that is in the button into a method. I then call that method on the button once clicked and i still get the error message when you click on the button:

"Row associated with the currency manager's position cannot be made invisible."

This error occured on

row.visible = rowsVisible;

I declared the following line at the top of the program.

private bool rowsVisible;

I have declared in the following line the method

this.rowsVisible = false;

Do you know why this could be happening? Is it something to do with currency manager value?

Thanks

Well, I'm never using currency manager, so I really wouldn't know why this exception is thrown. But I do know that it is impossible to hide a new row in your datagridview (this is the last row in grid). Have to go now because I have run out of my laptop batery :-(
