Question

我一直在尝试在第1列的每个单元格之间进行换行：

值1，值2，
价值3

然而，换行符只是在单元格中显示为纯文本：

<asp:GridView ID="dg1" runat="server" AllowSorting="true" OnSorting="Sort" AutoGenerateColumns="false" OnSelectedIndexChanged="dg1_SelectedIndexChanged" CssClass="DGgeneral" HeaderStyle-CssClass="DGheader" RowStyle-CssClass="DGrow1" AlternatingRowStyle-CssClass="DGrow2" >
    <Columns>

     </Columns>
</asp:GridView>

我正在以编程方式执行所有操作，因此我无法将HTMLEncode="false"添加到BoundFields，这是一个巨大的痛苦。

 public void SearchQuery(string sOrderBy, string sOrderByColumn)
    {
        //Create and Clear Datatable and Gridview

        dt.Clear();
        dg1.DataSource = null;
        dg1.DataBind();

        //Initialise Strings
        string sTLTaskID = "";
        string sTitle = "";
        string sForename = "";
        string sSurname = "";
        string sEmail = "";
        string sMobile = "";
        string sHome = "";
        string sDateTime = "";
        string sState = "";
        string sFormName = "";

        //Initialise Column Names

        dt.Columns.Add("Id/Form/State");
        dt.Columns.Add("Title");
        dt.Columns.Add("Forename");

在GridView的RowDataBound事件中添加以下行：

e.Row.Cells[0].Text = e.Row.Cells[0].Text.Replace("\n", "<br/>");

注意：您必须将OnRowDataBound事件添加到GridView，如下所示：

<asp:GridView ID="dg1" runat="server" OnRowDataBound="dg1_RowDataBound">
