ASP.NET VB KML Generator

由 痴心易碎 提交于 2019-12-09 19:33:27
问题 Here is a handler (ashx) file that generates KMZ files (can generate KML by not using the Ionic compression classes (Ionic = DotNetZip at Codeplex). This handler uses an SQL table to populate the place marks but is a good example of ashx handler use, custom icon use, properly compressing the file, and populating place marks. By using context.Response.OutputStream, this is very efficient within the .NET engine. <%@ WebHandler Language="VB" Class="YourKML" %> Imports System Imports System.Web

How can I apply GA download tracking with Sitecore?

由 和自甴很熟 提交于 2019-12-08 09:19:21

Since the 3rd party GA tracking tool I was using (entourage.js or gatags.js) does not recognize .ashx as a whitelisted download file, it was not adding the appropriate GA tracking syntax to the

Use ASP.Net server control code generation from .ashx

问题 I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via

ASP.NET - Display Images and pdf in a GridView

由 与世无争的帅哥 提交于 2019-12-08 00:38:59
问题 I want to display in an asp:GridView an "Images" column. The idea is to provide a thumbnails of the image with link to real size image. For some rows, this may alternatively be a PDF document.

Multiple image handler calls causing IE to hang in pop-up window

由 北城余情 提交于 2019-12-07 05:45:16
问题 We have an ashx image handler which has performed fairly well over the last few years, but we've recently noticed some odd intermittent behaviour in IE8 and IE9 . We have a gallery page which calls the image handler multiple times as part of an image's src attribute, this page is opened in a pop up window. The page works fine when but when the window is opened and closed in quick succession (before all the images on the page have finished loading) it causes the browser to hang and
