我想知道我是否可以在gridview中更改代码隐藏中的Container.DataItem。我的意思是,如果我想根据条件将Dataitem从“SellingPaymentMethod”更改为“DeliveryPaymentmethod”。
我使用相同的存储过程来获取销售和交付的信息。因此,如果它是销售它应该是SellingPaymentmethod,否则它应该是DeliveryPaymentmethod。这是在使用C#的ASP.Net中。
<asp:TemplateField ItemStyle-Width="70" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label ID="lblSellingPaymentMethod" runat="server"
Text='<%#DataBinder.Eval(Container.DataItem,"SellingPaymentMethod") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
if(Condition1 = "Selling")
{
use sellingpaymentmethod container
}
else
{
use deliverypaymentmethod
}
编辑:
if (e.Row.RowType != DataControlRowType.DataRow)
{
return;
}
foreach (DataRow dtrCurrentRow in (((System.Data.DataView)grdDetail.DataSource)).Table.Rows)
{
//DataRow row = (DataRow)e.Row.DataItem;
Label lblPaymentMethod = e.Row.FindControl("lblPaymentMethod") as Label;
Label lblBalance = e.Row.FindControl("lblTotalSold") as Label;
Label lblBalanceCollected = e.Row.FindControl("lblTotalCollected") as Label;
if (lblTypeofDay.Text == "Selling")
{
lblPaymentMethod.Text = dtrCurrentRow["SellingPaymentMethod"].ToString();
}
else if (lblTypeofDay.Text == "Delivery")
{
lblPaymentMethod.Text = dtrCurrentRow["DeliveryPaymentmethod"].ToString();
}
}
这就是我使用你的代码的方式。我不确定为什么所有行都在paymentmethod列中具有最后一行值。
我在btnSubmit_OnClick函数中有数据绑定代码
DataView myDataView = new DataView();
myDataView = dsnew.Tables[0].DefaultView;
grdDetail.DataSource = myDataView;
grdDetail.DataBind();

创建一个RowDataBound
事件处理程序并在那里进行更改。
.aspx的:
<asp:GridView id="gridView1" runat="server"
OnRowDataBound="gridView1_RowDataBound" />
代码背后:
public void gridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType != DataControlRowType.DataRow)
{
return;
}
DataRow row = (DataRow)e.Row.DataItem;
Label lblSellingPaymentMethod =
e.Row.FindControl("lblSellingPaymentMethod") as Label;
if(condition == true)
{
lblSellingPaymentMethod.Text = row["sellingpaymentmethod"].ToString();
}
else
{
lblSellingPaymentMethod.Text = row["deliverypaymentmethod"].ToString();
}
}
