Asp.net - Change Onclick Of An Image?
Feb 9, 2011
I have an html img
<img id="btnViewSpec" alt="View Spec Sheet"src="/images/viewspec.jpg" style="cursor: pointer;" />
I need to alter the onclick to target different aspx pages based on what's read from the database. Something like:
If DBRead("Keywords").ToString.Contains("glove") Then
Me.btnViewSpec.Attributes.Add("onclick", ("window.open('/SpecSheet/DisplayPDF.aspx?pa=/SpecSheet/GloveSpec.aspx?pid=" & intProductId & "','wnEmailInfo', 'menubar=no,width=820,height=500,toolbar=no,scrollbars=yes,status=yes')"))[code]....
Problem is I can't get the code behind to recognize the image. I tried to register it in the designer code with Protected WithEvents btnViewSpec As HtmlImage but no luck. I guess I just don't fully understand the issue or what gets registered in the designer code.

How can i load the original image when the tumbnail version of the image has been clicked? Im using ASP.NET in combinaton with javascript.
The original images are big, so they have been scaled on server side. This makes the site load faster. But somehow, both versions (original and tumbnail) of the images are being downloaded.
I'm trying to download only the tumbnail version of the image. And when the user clicks on the image, i want to show the original image.

I'm from Holland (The Netherlands) and new to this forum, I'm not 100% sure if I'm posting this thread in the correct subforum... I don't I have a little experience in Visual Basic .NET 2008 Currently I'm developing a program for my job in which you can follow a checklist for doing a certain procedure. With every step you have to click a checkbox and so on. It's saved in an XLS-file and blahblah, all irrelevant for my question.
I've got to the point that I'm almost pulling my hair here, because everything went fine so far with coding my program, but this simple thing I can't solve What I'm trying to do is, change the BackgroundImage of a Button when you click on it. If it is Image1 at the time of clicking it should change to Image2, and vice versa.

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

How do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.

I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.

I'm wondering if it's possible to make sort of resource to change every button on a form to a resource image
so you make a form and every button on the form loads as a image from a resource you added
I want to make this globally and not by going on all the buttons and changing them one by one

I have an image scanned in 300 dpi. I want to change the DPI of the image to 72 through code. Seems there used to be a function called Image.SetDPI, but I cannot find it anymore. All I can find is Image.SetResolution(xDPI, yDPI), but that actually changes the SIZE of the image, meaning it cuts out a portion of it, without changing the DPI. Anyone know what function will accomplish this in Visual Studio 2008?

I've been looking into creating custom controls, and I can't seem to find a good tutorial on how to do so. Everything I've looked at is extremely complex and I simply don't know where/how to start.
To start out with, all I want to do is change the image of the button (normal, hover, and clicked). No extra methods/events/properties/etc. I've made individual images for each situation with Photoshop.

I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:
- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)
I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.

I'm converting a VB project to C#, and I notice that in vb it will call a function like:[code]on the asp.net source page or it will never hit the function. Is this a necessity in c#, or is there something that I'm overlooking or missing? Basically, is there a way in c# for it to hit that function like in VB without adding the line above in the source page?

Am displaying list of available documents in the data grid which are retrieved from the database. Once we click on a specific one then it will retrieve PDF document from the server and display it in the browser.Currently, if I click a document from the list in the datagrid then it will display the PDF file in a new browser. Here is the code for that :
ds.Tables(0).Rows(i).Item("DOC") = "<font color=blue onmouseover=""this.style.cursor='hand';"" title=""Click for PDF"" " + _
"onclick=""location.replace('index.aspx?Name=" & link & "')"">" & docNum & "</font>"
