如何在GridView中使用ButtonField打开新选项卡/页面

<asp:GridView ID ="FileGrid" runat="server" AutoGenerateColumns="False" OnRowCommand="FileGrid_RowCommand">
    <Columns>
        <asp:BoundField DataField="OriginalFileName" HeaderText="OriginalFileName" SortExpression="OriginalFileName" /> 
        <asp:BoundField DataField="AttachmentGUID" HeaderText="AttachmentGUID" SortExpression="AttachmentGUID" />             
        <asp:ButtonField Text="Generate PDF" runat="server" HeaderText="Convert To PDF" CommandName="GeneratePDF_Click" />
    </Columns>
</asp:GridView>

Code Behind:

代码背后：

protected void FileGrid_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "GeneratePDF_Click")
    {
        int num = Convert.ToInt16(e.CommandArgument);
        string attachmentGuid = FileGrid.Rows[num].Cells[1].Text;
        Response.Redirect("DisplayImage.aspx?AttachmentGUID=" + attachmentGuid);
    }
}

I see a lot of solutions using OnClientClick with a asp:Button, but I'm unable to use a asp:Button within a column?

我看到很多使用OnClientClick和asp：Button的解决方案，但是我无法在列中使用asp：Button？

You can use ScriptManager.RegisterStartupScript to open up a new window:

您可以使用ScriptManager.RegisterStartupScript打开一个新窗口：

var url = "DisplayImage.aspx?AttachmentGUID=" + attachmentGuid;
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "popup", "window.open('" + url + "','_blank')", true);

or you can also try:

或者您也可以尝试：

var url = "DisplayImage.aspx?AttachmentGUID=" + attachmentGuid;
string redirect = "<script>window.open('" + url + "');</script>"; 
Response.Write(redirect);
