ASP.NET将多个页脚行添加到Gridview(ASP.NET Adding Multiple footers rows to Gridview)

ASP.NET将多个页脚行添加到Gridview(ASP.NET Adding Multiple footers rows to Gridview)

也就是说，我正在向网格视图中添加一个页脚行，如下所示

Protected Sub gvShoppingCart_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvShoppingCart.RowDataBound ' If we are binding the footer row, let's add in our total If e.Row.RowType = DataControlRowType.Footer Then e.Row.Cells(5).Text = "<strong>Total Cost:</strong>" e.Row.Cells(6).Text = ShoppingCart.Instance.GetSubTotal().ToString("C") End If End Sub

如何添加更多页脚行，即总折扣，总保存等同样如上所述

i.e at the moment I am adding a footer row to my gridview as follows

Protected Sub gvShoppingCart_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvShoppingCart.RowDataBound ' If we are binding the footer row, let's add in our total If e.Row.RowType = DataControlRowType.Footer Then e.Row.Cells(5).Text = "<strong>Total Cost:</strong>" e.Row.Cells(6).Text = ShoppingCart.Instance.GetSubTotal().ToString("C") End If End Sub

How can I add more footer rows i.e. Total Discount, Total Saved etc likewise as above

最满意答案

这是一些基于页脚行插入新行的代码。 您可以修改它以插入多行。

Protected Sub gvShoppingCart_DataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvShoppingCart.DataBound Dim grid as GridView = CType(sender, GridView) ''gets the current footer row to clone Dim footer As GridViewRow = grid.FooterRow Dim numCells = footer.Cells.Count Dim newRow As New GridViewRow(footer.RowIndex + 1, -1, footer.RowType, footer.RowState) ''have to add in the right number of cells ''this also copies any styles over from the original footer For i As Integer = 0 To numCells - 1 Dim emptyCell As New TableCell emptyCell.ApplyStyle(grid.Columns(i).ItemStyle) newRow.Cells.Add(emptyCell) Next newRow.Cells(5).Text = "Total Discount:" newRow.Cells(6).Text = "55.00" ''add new row to the gridview table, at the very bottom CType(grid.Controls(0), Table).Rows.Add(newRow) End Sub

Here's some code for inserting a new row, based on the footer row. You could modify it to insert multiple rows.

Protected Sub gvShoppingCart_DataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvShoppingCart.DataBound Dim grid as GridView = CType(sender, GridView) ''gets the current footer row to clone Dim footer As GridViewRow = grid.FooterRow Dim numCells = footer.Cells.Count Dim newRow As New GridViewRow(footer.RowIndex + 1, -1, footer.RowType, footer.RowState) ''have to add in the right number of cells ''this also copies any styles over from the original footer For i As Integer = 0 To numCells - 1 Dim emptyCell As New TableCell emptyCell.ApplyStyle(grid.Columns(i).ItemStyle) newRow.Cells.Add(emptyCell) Next newRow.Cells(5).Text = "Total Discount:" newRow.Cells(6).Text = "55.00" ''add new row to the gridview table, at the very bottom CType(grid.Controls(0), Table).Rows.Add(newRow) End Sub
