I have able to generate several labels and textboxes based on a table in the database during runtime. My problem is that I could not get these values from these textboxes whenever a user changes these values and update them.

View 4 RepliesI have a DataTable where the columns are generated programmatically at runtime. I then bind this DataTable to a GridView. What I'm wondering is how I can create the GridView to accommodate this, and if it's not possible, how I can output the DataTable into nicely formatted HTML.
View 3 RepliesI have a Winforms app which provides the ability for users to create their own reports. At its simplest they design the query which gets encrypted and saved into a database.
The ability to view these reports via the web as now come upon us.
What is the best way to handle this? Ideally I want to use MVC but there will be no model or viewmodel because these queries can return data for any table across the application and so I cannot have hardcoded propeties etc. Obviously I have access to the SQL to execute it.
I wonder if tradtional ASP.Net may perform better in this scenario ie/execute the SQL and put it in a DataTable but was hoping to get some thoughts from the community.
Problem for me is that a tag is being generated that apparently just moves the treview a little bit. So I am thinking I should delete it at runtime. How do I do that?
Code:
<a href="#MainContent_TreeView2_SkipLink">
<img height="0" width="0" style="border-width:0px;" src="/.../WebResource.axd?d=2Lx-Wo-AmOSQUgrfkZW7jw2&t=634209174377343750" alt="Skip Navigation Links.">

View 1 RepliesI have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file. mycontrol.ascx embeds a single reference to a custom control: "MyMenu":
<mM:myMenu id="myMenu1" runat="server" />
This has created a protected reference in the mycontrol.ascx.designer.vb file:Protected WithEvents myMenu1 As Global.CustomControls.MyMenuNow, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:
Me.GetType().GetMembers()
I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible:
Me.myMenu1 Can anyone explain exactly what I'm missing and what I need to do to access designer created properties at runtime through reflection?
I have an aspx page that loads a static graphic and put session strings in it. I used Image1.Save(Server.MapPath("gen_img2.jpg"), ImageFormat.Jpeg), but it's not saved on the server. I thought this was a user permission problem, so I assigned the ASPNET account write permission to the folder, and it still doesn't work. Did I use the wrong account? I use winserver 2003 and IIS 6.

How to print barcode
provide me sample code for me ASAP.
I am learning asp.net using Visual web developer 2008 express.
I have an image control with the html code below
<div class="Header">
<asp:Image ID="image1" runat="server"
ImageUrl="D:/Master/test.jpg" Width="500" Height="300"
AlternateText="UNRA Fort Portal Intranet"/>
</div>
In design view, the image shows but when i run the app, the image is not shown. Only the alternate text is displayed.
The css code code as below.
.Header
{
top:10px;
left:20px;
position:absolute;
width:800px;
background-image:URL(D:/Master/test.jpg);
background-repeat:repeat-x;
}
I have a website on GoDaddy. All permissions are set correctly and the image DOES exist. However when the page loads the image for the item selected does not show. Here is my code
imagepath = "~/spaimages/" + currentSpaModel.Name.ToString() + ".png";
if (File.Exists(Server.MapPath(imagepath)))
{ this.spaimage.ImageUrl = Server.MapPath(imagepath); }
spaimage is an ASP control and thr URL that the image is set to is D:hostingxxxxxxxcalspasspaimagesmodelname.png
I have two scripts inside my webpage
<script type="text/javascript" src="http://somesite/somefile.js"></script> <script type="text/javascript" >somecode('a','1z4j73');</script>
This script is generating a visitor map on my web page, now I don't want my user to click on the script and get redirect to that website. How can I restrict that? Can I make a div tag and make all element inside the div tag to read only? I have make sure that this restriction doesn't falls under company rules, they just want their logo under the map. Can I catch this through any event and again redirect the user to the default page? Like when user click the image, I check the URL and if the URL contains that site name I again redirect to the default page.
I have one ogoing thread [URL]. IN addition to this thread I would like to insert image in newly generated word document. My problem here I can give our hosted server path using Img Source property. I want to copy or embed the imaged in the word document.
Let me know what is the best way to do it using asp.net/C#.
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.
View 2 RepliesI have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

I am converting a web forms site to MVC and there are a lot of pages all with an individual screenshot image on. Rather than have a separate page for each screenshot image, I though a better way to do this would be to have one page, and to pass the image details into a Controller method, and then set the src value of the <img> in my code. Does anybody know how to do this, and even if it is a good idea to be making reference to UI elements in my Controller code?
