Hi...

I want to search multiple records in AxMSFlexGridLib but following error is happening..

Cross-thread operation not valid: Control 'dateTimePicker1' accessed from a thread other than the thread it was created on.

below is code.

public void SearchCode_Method()
        {
            this.flex1.set_ColWidth(0, 0x177);
            this.flex1.set_ColWidth(1, 0x3e8);
            this.flex1.set_ColWidth(2, 0x9c4);
            this.flex1.set_ColWidth(3, 800);
            this.flex1.set_ColWidth(4, 600);
            this.flex1.set_ColWidth(5, 0x44c);
            this.flex1.set_ColWidth(6, 0x44c);
            this.flex1.set_ColWidth(7, 0x3e8);
            this.flex1.set_TextMatrix(0, 0, "S#");
            this.flex1.set_TextMatrix(0, 1, "CCode");
            this.flex1.set_TextMatrix(0, 2, "Name");
            this.flex1.set_TextMatrix(0, 3, "Invoice#");
            this.flex1.set_TextMatrix(0, 4, "Qty");
            this.flex1.set_TextMatrix(0, 5, "Bkg Date");
            this.flex1.set_TextMatrix(0, 6, "Dlv Date");
            this.flex1.set_TextMatrix(0, 7, "Amount");
            this.flex1.set_ColAlignment(1, 5);
            this.flex1.set_ColAlignment(3, 5);
            this.flex1.set_ColAlignment(4, 5);
            this.flex1.set_ColAlignment(5, 5);
            this.flex1.set_ColAlignment(6, 5);
            this.flex1.set_ColAlignment(7, 5);
            this.colno = 3;
            if (this.deliverd)
            {
                this.table = this.dsdata.Tables[6];
            }
            else if (this.nondelivered)
            {
                this.table = this.dsdata.Tables[7];
            }
            else
            {
                this.table = this.dsdata.Tables[3];
            }
            int num2 = 1;
            int num3 = 1;
            foreach (DataRow row in this.table.Rows)
            {
                if (num3 >= this.flex1.Rows)
                {
                    this.flex1.Rows++;
                    this.flex1.set_ColWidth(7, 750);
                }
                this.flex1.set_TextMatrix(num2, 1, Convert.ToString(row["CCode"]));
                this.flex1.set_TextMatrix(num2, 2, Convert.ToString(row["Name"]));
                this.flex1.set_TextMatrix(num2, 3, Convert.ToString(row["InvoiceNo"]));
                this.dateTimePicker1.Text = Convert.ToString(row["BookingDate"]);
                this.flex1.set_TextMatrix(num2, 5, this.dateTimePicker1.Value.ToShortDateString());
                this.dateTimePicker1.Text = Convert.ToString(row["DeliveryDate"]);
                this.flex1.set_TextMatrix(num2, 6, this.dateTimePicker1.Value.ToShortDateString());
                foreach (DataRow row2 in this.dsdata.Tables[0].Rows)
                {
                    if (row["Invoiceno"].ToString() == row2["InvoiceNo"].ToString())
                    {
                        this.flex1.set_TextMatrix(num2, 4, Convert.ToString(row2["Quantity"]));
                        this.flex1.set_TextMatrix(num2, 7, Convert.ToString(row2["Amount"]));
                    }
                }
                num3++;
                num2++;
            }
            for (int i = 1; i < num3; i++)
            {
                this.flex1.set_TextMatrix(i, 0, Convert.ToString(i));
            }
            this.searchDataset(this.table, this.dsdata.Tables[0], "CCode");
            this.btnPrint.Enabled = true;
