Question

我在gridview的rowdatabound事件中使用gridview列进行格式化。但是当我执行代码并使用立即窗口调试它时，我在e.Row.Cells [1] .Text中没有得到任何东西。我正在从数据表中填充gridview。它正在显示记录，但我不知道为什么它没有进入rowdatabound 以下是我的绑定代码

<asp:GridView runat="server" AutoGenerateColumns="False"  
                        ID="gviewTemplate" onrowdatabound="gviewTemplate_RowDataBound" DataKeyNames="F1"
                        onrowcommand="gviewTemplate_RowCommand" 
                        onrowediting="gviewTemplate_RowEditing" 
                        onrowcancelingedit="gviewTemplate_RowCancelingEdit" 
                        onrowupdating="gviewTemplate_RowUpdating">
                        <Columns>
                            <asp:TemplateField>
                                <EditItemTemplate>
                                    <asp:Label ID="lblID" runat="server" Text='<%# Bind("F1") %>'></asp:Label>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label Runat="server" Text='<%# Bind("F1") %>' ID="lblID1"></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="Uploaded Image">
                            <EditItemTemplate>

                                <ItemTemplate>
                                    <asp:Label Runat="server" Text='<%# Eval("Uploaded") %>' ID="lblUploaded"></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="Template Name">

                                    <asp:TextBox ID="txtTemplateName" Width="50" Runat="server" Text='<%# Eval("F2") %>'></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" Runat="server" 
                                    ErrorMessage="You must provide a Product Name." ControlToValidate="txtTemplateName">*</asp:RequiredFieldValidator>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="lblTemplateName" runat="server" Text='<%# Eval("F2") %>'></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="Heading">
                                <ItemStyle VerticalAlign="Top" HorizontalAlign="Center" />
                                <EditItemTemplate>
                                    <asp:TextBox ID="txtHeading" Runat="server" Width="50" Text='<%# Eval("F3") %>'></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator2" Runat="server" 
                                    ErrorMessage="You must provide a Product Name." ControlToValidate="txtHeading">*</asp:RequiredFieldValidator>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="lblHeading" runat="server" Text='<%# Eval("F3") %>'></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:TemplateField HeaderText="Coupon Text">
                                <ItemStyle VerticalAlign="Top" HorizontalAlign="Center" />
                                <EditItemTemplate>
                                    <asp:TextBox ID="txtCouponText" Runat="server" Width="50" Text='<%# Bind("F4") %>'></asp:TextBox>
                                    <asp:RequiredFieldValidator ID="RequiredFieldValidator3" Runat="server" 
                                    ErrorMessage="You must provide a Product Name." ControlToValidate="txtCouponText">*</asp:RequiredFieldValidator>
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label Runat="server" Text='<%# Bind("F4") %>' ID="lblCouponText"></asp:Label>
                                </ItemTemplate>
                            </asp:TemplateField>

这就是我在rowdatabound中所做的事情

protected void gviewTemplate_RowDataBound(object sender, GridViewRowEventArgs e)
{
        if (e.Row.Cells[1].Text != e.Row.Cells[2].Text)
        {
            e.Row.BackColor = System.Drawing.Color.Red;
        }
 }

我无法理解记录是否在网格中显示为什么我无法在rowdatabound中获取

Answer 1

因为你在网格中使用模板字段，所以尝试调试并保持单元格，然后尝试在其中找到文本框，然后读取它的值

Answer 2

试试这个：
你需要检查rowtype，因为在行数据绑定中它还包括页眉，页脚

protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow & (e.Row.RowState == DataControlRowState.Normal | e.Row.RowState == DataControlRowState.Alternate)) {
            //your code here
        }
    }
