I have 30 buttons and I am trying to implement context menu on each button click by using following method.

void OnButtonClick(object sender, EventArgs e)
    {
        Button btn = (Button)sender;
        btn.ContextMenuStrip.Show(btn, new System.Drawing.Point(0, btn.Height));
    }

I have 2 context menu strip items, Add text Label and Add colour

private void addTextLabelToolStripMenuItem_Click(object sender, EventArgs e)
{
foreach (Control item in panel2.Controls)
{
Button btn = (Button)item;
if (string.IsNullOrEmpty(btn.Text.Trim()))
{
frmAddText form = new frmAddText();
form.ShowDialog();

                if (frmAddText.IsTextMod)
                {
                    return;
                }
                btn.Text = form.TextInfo;
                btn.Tag = 0;
            }				} }

Wen i try to do this it is implementing on last button itself. Here Ia m returning Here foreach is not acceptable.

private void addColourToolStripMenuItem_Click(object sender, EventArgs e)
{
colorDialog1.ShowDialog();
DialogResult dResult = colorDialog1.ShowDialog();
foreach (Control item in panel2.Controls)
{
Button btn = (Button)item;
string strBtnName = btn.Name;
if (string.Equals(btn.Name, strBtnName, StringComparison.OrdinalIgnoreCase))
{
if (dResult == DialogResult.OK)
btn.BackColor = colorDialog1.Color;
} } }

It is applying color to all buttos. But it should apply for only specific clicked button. Here foreach is not acceptable.

dtpFromDate & dtpTodate are DateTimepickers and a TextBox txtNoofDays

private void dtpFromDate_ValueChanged(object sender, eventArgs e)

}

Here I got the error at--> //double value ---- Input string was not in correct format How to resolve It.
