Question

Actually, I have fired an event on DataGridView_CellContentClick which perform an operation relating to datagridview like changing cell’s value But before performing this action i want to make changes(or fire) an another operation on another control i.e. ListView .But this is not gone happens although i place another operation before datagridview’s operation. Anybody please help me out.

And my code goes like this:-

    private void dGridDeviceList_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        //DataGridViewCell dcell = dGridDeviceList.Rows[e.RowIndex].Cells[e.ColumnIndex];
        if (e.RowIndex >= 0)
        {
            ListViewItem litem1 = lvInformation.Items.Add("101");

            litem1.SubItems.Add(string.Empty);
            litem1.SubItems[1].Text = "Connected.";

          ListViewItem litem5=  lvErrorList.Items.Add("check ");
            Cursor = Cursors.WaitCursor;
            List<cException> cxp = new List<cException>();
            cDeviceModel cdm = new cDeviceModel();
            ListViewItem litem = new ListViewItem();
            DataGridViewRow drow = new DataGridViewRow();
            cDeviceUtility cUtil = new cDeviceUtility();
            List<cAction> catn = new List<cAction>();
            drow = dGridDeviceList.Rows[e.RowIndex];
            cdm = (cDeviceModel)drow.Tag;
            if (e.ColumnIndex == 6)
            {

                if (dGridDeviceList.CurrentCell.Value.ToString() == "Connect")
                {
                    litem1= lvInformation.Items.Add("101");

                   litem1.SubItems.Add(string.Empty);
                   litem1.SubItems[1].Text = "Connected.";

                    //lvInformation.Items.Insert(0, "101");
                    //lvInformation.Items[0].SubItems.Add("Connected");
                }
                // connect disconnect button column
                if (cdm.IsConnected)
                {
                    ListViewItem litem2 = lvInformation.Items.Add("102");

                    litem2.SubItems.Add(string.Empty);
                    litem2.SubItems[1].Text =string.Format("Disconnecting from {0} device.",dGridDeviceList.CurrentRow.Cells["colDeviceName"].Value);

                    // then disconnect the device
                    cdm.IsConnected = false;
                    cdm.DeviceInterface.Disconnect();

Answer 1

considering this is winform

 private void buttonCopyContent_Click(object sender, EventArgs e)
{
//do something
}

you can call this event via following line
this.Invoke(new EventHandler(buttonCopyContent_Click));
