I want to hide the ID column.

Here is the code that i am using, I have already declared this.dataGridView.Columns["ID"].Visible = false , but the ID column is still visible.

private void PrintPreview(object sender, EventArgs e)

            _PrintPreview.Document = printDocument1;
            ((Form)_PrintPreview).WindowState = FormWindowState.Maximized;
            _PrintPreview.ShowDialog();

Any help how do i fix this?

Thank you!

Your answer will be great appreciated!

Answer 1

I think the problem is in printDocument1_PrintPage:

foreach (DataGridViewColumn GridCol in dataGridView1.Columns)
{
    e.Graphics.FillRectangle(new SolidBrush(Color.Aqua), new Rectangle((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight));

    e.Graphics.DrawRectangle(Pens.Black, new Rectangle((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight));

    e.Graphics.DrawString(GridCol.HeaderText, GridCol.InheritedStyle.Font, new SolidBrush(GridCol.InheritedStyle.ForeColor), new RectangleF((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight), strFormat);

    iCount++;
}

You are looping over ALL columns and printing thier values. So you should skip the ID column. Keep in mind that changing particular column Visible property to false will not hide it from the dataGridView1.Columns collection.

Anyway, one easy way to achieve your goal:

foreach (DataGridViewColumn GridCol in dataGridView1.Columns)
{
    if (GridCol.Name != "ID")
    {
        e.Graphics.FillRectangle(new SolidBrush(Color.Aqua), new Rectangle((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight));

        e.Graphics.DrawRectangle(Pens.Black, new Rectangle((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight));

        e.Graphics.DrawString(GridCol.HeaderText, GridCol.InheritedStyle.Font, new SolidBrush(GridCol.InheritedStyle.ForeColor), new RectangleF((int)arrColumnLefts[iCount], iTopMargin, (int)arrColumnWidths[iCount], iHeaderHeight), strFormat);

        iCount++;
    }
}

Answer 2

Try to put your this line this.dataGridView1.Columns["ID"].Visible = false; as the first line of your PrintPreview method, because when you call _PrintPreview.ShowDialog(); will call printDocument1_BeginPrint and hence that column is visible.

Answer 3

As Mo.Ashfaq already answered, you have a logical mistake here

    private void PrintPreview(object sender, EventArgs e)
    {
        ...
        _PrintPreview.ShowDialog();

        this.dataGridView1.Columns["ID"].Visible = false;
    }

make it this way

    private void PrintPreview(object sender, EventArgs e)
    {
        ...
        this.dataGridView1.Columns["ID"].Visible = false;
        _PrintPreview.ShowDialog();
        this.dataGridView1.Columns["ID"].Visible = true; // restore visibility
    }

next thing is what setting column invisible doesn't prevent from enumerating it (as etaiso answered), replace all occurrences

foreach (DataGridViewColumn dgvGridCol in dataGridView1.Columns)
{
    ...
}

with

foreach (var column in dataGridView1.Columns)
    if(column.Visible)
    {
        ...
    }

Answer 4

try not having the parameter of the ID column at all to visible being false or true.

But as etaiso said you are looping through all the columns when you execute your loop through all the rows.

All you need to do is this change

                int iCount = 0;

to

                int iCount = 1;

that way you skip the first column in your for loop and the ID column, column 0 won't appear in your print preview
