[英]Pass Data from inner grid View to main grid view (gridview in gridview template)ASP.net C#
我在將數據從內部網格傳遞到主網格時遇到了一些麻煩，如圖所示
我嘗試了太多的解決方案，我可以使用 C# 和 Jquery 這是簡單的照片結果
現在這是從數據庫讀取的發票以顯示多個數據，如圖所示，網格包含另一個網格，正常代碼無法訪問 gridview2 來獲取數據
我想要的只是從gridview2獲取“金額”然后計算“sum”然后將其傳遞給gridview1中的“total”我也使用Jquery它什么都不做這是兩個字段的簡單代碼我想用Jquery求和
<script type="text/javascript"> $(function () { var fields = document.getElementsByClassName('clstocal'); var sum = 0; for (var i = 0; i < fields.length; ++i) { var item = fields[i]; sum += parseInt(item.innerHTML); } $("#totalprice").text(sum); }); // this code get it from this site </script>
<asp:TextBox ID="amount" CssClass ="clstocal" autopostback="true" runat="server" Enabled="False" Height="24px" Text='<%# Bind("body_total") %>' Width="98px" OnTextChanged="amount_TextChanged"></asp:TextBox>
和
<asp:TextBox ID="totalprice" runat="server" Enabled="False" Height="22px" Width="145px" OnTextChanged="totalprice_TextChanged" autopostback="true"></asp:TextBox>
有一個簡單的解決方案，但不是一個好的解決方案是將結果匯總到數據庫然后再次讀取，但這根本沒有效率..
老實說，答案很簡單 1. 無法訪問網格內的網格 2. 通過 C# 中的普通代碼解決，如圖所示
protected void GridHead(object sender, GridViewRowEventArgs e)
{
// MAin Grid which is grid number 1
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox textboxPrice1 = e.Row.FindControl("totalprice") as TextBox;
textboxPrice1.Text = i.ToString();
i = 0; // Global double -> protected double i = 0; // THIS LINE TO STOP COUNTING TO OTHER NEXT INVOICE
}
}
protected void GridBody(object sender, GridViewRowEventArgs e)
{
// Inner grid which contain multipe item need to sun then send it to Main grid
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox lblPrice2 = e.Row.FindControl("amount") as TextBox;
i += Convert.ToDouble(lblPrice2.Text);
}
}
以及處理網格的代碼
