I have an image loaded in a div element. (This image will be added dynamically thru JS, based on the option selected by the user).
I have a requirement to open this image in Word, Excel and Pdf applications when those icons (given in the page) are clicked, respectively.

The same code works fine to render a gridview in excel, but not an image. I also tried placing the image element in a table tag.

I have a aspx.cs page that renders a pdf file directly.
To render the pdf directly i have to use ContentType="applicationpdf" in my .aspx page.
The problem I am facing now is:
I need a time-request field - namely, the user would have to enter the time (from and to) and hit Go and the pdf will be rendered according to the date-requested.
However, I cannot display the time-request (or page option) field and render the pdf simultaneously.
I have set an image control in a web page. The image show correctly in desgin time but just show an "x" in run time.
I am using vs2008 installed in Windows 7. The problem didn't found when I used the vs2008 in windows vista.
I have a complicated user control on a form that's laid out they way the business unit wants it. What they would like is to be able to export this content to excel and/or PDF as an image. Basically I need to be able to render the user control as a static image.
Is there any simple way to do this or is it even possible? Since the user control is HTML, it's not really rendered at all at the server level as it's just HTML, so I would assume that I might need to interface with IE library.
I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?

I am developing a .Net Page that will contain a FileUpload box so a user can upload images to the site. I would like the functionality that when someone chooses a file to upload (before they actually upload the file), they can preview it on the browser. I know I can do this through some javascript magic, but is there anything that can be done using AJAX tools to gain this functionality.
View 3 RepliesI need to export a gridview to excel and am having trouble with the layout. I found a number of good articles that explain the basic mechanics of the export. One simple approach that works is:
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.xls"
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
grdExcelExport.RenderControl(htmlWrite)
Response.Write(stringWrite.ToString())
Response.[End]()
My issue is that the gridview that appears on the screen with all of its added rows, hidden columns, and such does not show properly in Excel - the hidden columns from the header now show; there are missing data rows and so forth.
The RowDataBound event adds rows in the Header - these do not make it into Excel. The sql code does a GROUP BY WITH ROLLUP and the last total rows do not show in Excel, although the intermediate ones do. After my first DataBind of the table, I append 5 rows of special summary information which the RowDataBound processes correctly, but none of this goes to Excel.
So my wonderful Gridview on the screen becomes worthless in the transfer. How do I get my highly custom-formatted gridview into Excel??
I need displaying my image file stored from my database into the image control. I've had read some articles and watch video tutorial which there were perfectly working and I followed it but I wasn't able to make it work. The image control just displayed blank. I used Generic Handler to retrieve the image file from my database based on the articles and tutorials I've got. here are my codes below:
Generic Handler:
Code:
<%@ WebHandler Language="C#" Class="ShowImage" %>
using System;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;
[Code] ....
Asp.Net Code for the Image control:
HTML Code:
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ShowImage.ashx?ID=" + Eval("ID") %>' Height="128px" />
Imagine there's a web (mvc) application, which home directory on the server is the default c:intepubwwwroot. What i need is: user requests [URL] Server responses with a simple page with a random picture on it from a predefined path, which is not iis folder/app, like d:lolcats. This sample is tremendously simplified, of course. My solution is: when /randomPicture/ is requested, copy random picture to APP_Images/current_response.jpg or whatever to application home folder and then simply render <img src="../APP_Images/current_response.jpg" />
View 2 RepliesI am doing a rework on one of my sites and I am attempting to use the asp:menu control.
I am using images in the static and dynamic menus. Hard coded at this point.
On my local machine it works fine but when I upload to the server, the image on the dynamci menus do not appear.
Instead I just get white space where the images should be.
Here is the code:

View 1 RepliesI've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

I have a web service which is accessible from the browser. When I try to access the same web service which is hosted on Windows Server 2008 R2, from an excel Macro, it says
Run-time error '-2147220991' (80040201)':

The excel macro works fine when I try to access the same web service on the other server(Windows 2000 Server)
