                   BarCodePrint();
			GetQuantity();


            }
        }



        private void BarCodePrint()
        {
            inventoryDS1.BarCode.Clear();
            Connection();
            da = new SqlDataAdapter("select * from DeliveryChallan Where DcNo='"+TbDCNos.Text+"' OR UDcNo='"+TBUDcNo.Text+"'", cs);
            DataTable dt = new DataTable();
            da.Fill(dt);
            if (dt.Rows.Count > 0)
            {
                foreach (DataRow Row in dt.Rows)
                {
                    inventoryDS1.BarCode.ImportRow(Row);
                }
                LoadBcReport();
                ReportBCData();
                string FilePath = Application.StartupPath + "\\BCEndUser.txt";
                XtraReport.BarCoding XRBC = new XtraReport.BarCoding();
                XRBC.LoadLayout(FilePath);
                XRBC.DataSource = inventoryDS1.BarCode;
                XRBC.ShowPreview();
            }
            else
            {
                MessageBox.Show("No BarCode To Print");
            }
            cs.Close();
        }

        private void GetQuantity()
        {
            foreach (ListViewItem Item in listView1.Items)
            {
                for (int BCount = 1; BCount < Convert.ToInt16(Item.SubItems[6].Text); BCount = BCount + 1)
                {
                    DataSet.InventoryDS.BarCodeRow BCR = inventoryDS1.BarCode.NewBarCodeRow();
                    BCR.ModelCode = Convert.ToString(Item.SubItems[1].Text);
                    BCR.ModelName = Convert.ToString(Item.SubItems[2].Text);
                    BCR.ModelSize = Convert.ToString(Item.SubItems[4].Text);
                    BCR.Quantity = Convert.ToString(BCount);
                    BCR.MRPRate = Convert.ToString(Item.SubItems[7].Text);
                    inventoryDS1.BarCode.Rows.Add(BCR);
                }
            }
        }

推荐答案

点击打印后，获取所有标记的项目检查。您可以将它们放在临时数据表中。完成后，使用此临时表打印项目。



逐步尝试。上面的代码是填充而不是选择。在尝试打印之前，您需要找到所选的值。

On print click, get all the items that are marked checked. You can put them in a temporary datatable. Once done, use this temporary table to print items.

Take stepwise and try out. Code above is to populate and not about selection. You need to find selected value before trying to print it.

private void BtnBarCode_Click（object sender，EventArgs e）

{

inventoryDS1.BarCode.Clear（）;



foreach（listView1.CheckedItems中的ListViewItem项目）

{

if（Item.Checked == true）

{

for（int BCount = 0; BCount< Convert.ToInt16（Item.SubItems [6] .Text）; BCount = BCount + 1）

{

DataSet.InventoryDS.BarCodeRow BCR = inventoryDS1.BarCode.NewBarCodeRow（）;

BCR.ModelCode = Convert.ToString（Item.SubItems [1] .Text）;

BCR.ModelName = Convert.ToString（Item.SubItems [2] .Text）;

BCR。 ModelSize = Convert.ToString（Item.SubItems [4] .Text）;

BCR.Q uantity = Convert.ToString（BCount）;

BCR.MRPRate = Convert.ToString（Item.SubItems [7] .Text）;

inventoryDS1.BarCode.Rows.Add （BCR）;

}

}

}

string FilePath = Application.StartupPath +\\\ \\ BCEndUser.txt;

XtraReport.BarCoding XRBC = new XtraReport.BarCoding（）;

XRBC.LoadLayout（FilePath）;

XRBC .DataSource = inventoryDS1.BarCode;

XRBC.ShowPreview（）;

}

private void BtnBarCode_Click(object sender, EventArgs e)
{
inventoryDS1.BarCode.Clear();

foreach (ListViewItem Item in listView1.CheckedItems)
{
if (Item.Checked == true)
{
for (int BCount = 0; BCount < Convert.ToInt16(Item.SubItems[6].Text); BCount = BCount + 1)
{
DataSet.InventoryDS.BarCodeRow BCR = inventoryDS1.BarCode.NewBarCodeRow();
BCR.ModelCode = Convert.ToString(Item.SubItems[1].Text);
BCR.ModelName = Convert.ToString(Item.SubItems[2].Text);
BCR.ModelSize = Convert.ToString(Item.SubItems[4].Text);
BCR.Quantity = Convert.ToString(BCount);
BCR.MRPRate = Convert.ToString(Item.SubItems[7].Text);
inventoryDS1.BarCode.Rows.Add(BCR);
}
}
}
string FilePath = Application.StartupPath + "\\BCEndUser.txt";
XtraReport.BarCoding XRBC = new XtraReport.BarCoding();
XRBC.LoadLayout(FilePath);
XRBC.DataSource = inventoryDS1.BarCode;
XRBC.ShowPreview();
}
