Question

我有一个GridView，其中包含一个包含电子邮件的列。我希望用户能够双击该行并激活电子邮件链接以打开电子邮件的Outlook窗口。我有双击部分，但我不知道如何从行中获取电子邮件来创建网址。我将粘贴下面的代码。

<asp:GridView ID="gvAllDOL" runat="server" Visible="False" PageSize="25" AutoGenerateColumns="False" OnDataBound="gvAllDOL_DataBound" DataSourceID="odsDOAll" OnRowDataBound="gvAllDOL_RowDataBound" DataKeyNames="sintDistrictOfficeID" OnRowCommand="gvAllDOL_RowCommand" OnSelectedIndexChanged="gvAllDOL_SelectedIndexChanged">
                <Columns>
                    <asp:ButtonField Text="DoubleClick" CommandName="DoubleClick" Visible="false" />
                    <asp:TemplateField>
                        <ItemTemplate>
                            <asp:Label ID="lblid" runat="server" Text='<%# Bind("sintDistrictOfficeID") %>'></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:BoundField DataField="sintDistrictOfficeID" HeaderText="id" SortExpression="sintDistrictOfficeID" />     
                    <asp:BoundField DataField="vcharDOLOfficeName" HeaderText="DOL Office Name" SortExpression="vcharDOLOfficeName" />     
                    <asp:BoundField DataField="vcharDOLCity" HeaderText="City" SortExpression="vcharDOLCity" />
                    <asp:BoundField DataField="vcharDOLState" HeaderText="State" SortExpression="vcharDOLState" />
                    <asp:BoundField DataField="intBatchCount" HeaderText="Number Batches" SortExpression="intBatchCount" />
                    <asp:BoundField DataField="intCaseCount" HeaderText="Number Cases" SortExpression="intCaseCount" />
                    <asp:BoundField DataField="intExamCount" HeaderText="Number Examiners" SortExpression="intExamCount" />                        
                </Columns>
            </asp:GridView>


protected void gvCE_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onMouseOver", "Highlight(this)");

            e.Row.Attributes.Add("onMouseOut", "UnHighlight(this)");

            // Get the LinkButton control in the second cell
            LinkButton _doubleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];
            // Get the javascript which is assigned to this LinkButton
            string _jsDouble =
            ClientScript.GetPostBackClientHyperlink(_doubleClickButton, "");
            // Add this JavaScript to the ondblclick Attribute of the row
            e.Row.Attributes["ondblclick"] = _jsDouble;
        }
    }


protected void gvCE_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        string email = ((Label)gvCE.Rows[0].Cells[1].FindControl("lblEmail")).Text; (this doesn't work)


        GridView _gridView = (GridView)sender;


        string _commandName = e.CommandName;

        switch (_commandName)
        {
            case ("DoubleClick"):
                Response.Redirect("<a href=mailto:" + email + ">");
                break;
        }

    }     


protected override void Render(HtmlTextWriter writer)
    {

        foreach (GridViewRow r in gvAllDOL.Rows)
        {

            if (r.RowType == DataControlRowType.DataRow)
            {
                Page.ClientScript.RegisterForEventValidation
                        (r.UniqueID + "$ctl00");
                Page.ClientScript.RegisterForEventValidation
                        (r.UniqueID + "$ctl01");
            }
        }


        foreach (GridViewRow r in gvCE.Rows)
        {

            if (r.RowType == DataControlRowType.DataRow)
            {
                Page.ClientScript.RegisterForEventValidation
                        (r.UniqueID + "$ctl00");
                Page.ClientScript.RegisterForEventValidation
                        (r.UniqueID + "$ctl01");
            }
        }

        base.Render(writer);
    }

Answer 1

将您的电子邮件字段转换为模板字段。添加以下代码，然后尝试使用它：

<asp:HyperLink ID="EmailLink" runat="server" Text='Email' NavigateUrl= 
"mailto:" + '<%# Eval("yourBoundEmailFieldNameHere") %>'
</asp:HyperLink>

Answer 2

我会使用Manul的建议通过项目模板添加电子邮件地址

<asp:HyperLink ID="EmailLink" runat="server" Text='Email' NavigateUrl= 
"mailto:" + '<%# Eval("yourBoundEmailFieldNameHere") %>'
</asp:HyperLink>

通过这种方式，您可以访问电子邮件地址，人们可以看到他们将通过电子邮件发送电子邮件。然后将此脚本添加到页面

$("table tr").dblclick(function () {
    var mailto_link = $('a', $(this)).attr('href');
    window = window.open(mailto_link, 'emailWindow');
    if (window && window.open && !window.closed) 
        window.close();
});

然后删除将javascript函数添加到网格中每一行的代码，因为不再需要它。

Answer 3

您可以使用命令参数传递电子邮件地址，从而大大简化了检索地址所需的逻辑。

将Command按钮列更改为TemplateField并在其中添加asp：按钮。然后将属性CommandArgument添加到按钮。

<asp:TemplateField>
    <ItemTemplate>
        <asp:Button ID="dblClick" runat="server" Text="dblClick" 
            CommandArgument="<%# ((GridViewRow) Container).RowIndex %>"
            CommandName="dblClick" />
    </ItemTemplate>
</asp:TemplateField>

然后在

背后的代码中

protected void gvCE_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        string email = e.CommandArgument;

将电子邮件网址添加到gridview行，然后双击打开电子邮件窗口
