Web Forms :: Image Buttons Wont Load On Running
Aug 11, 2010
Im using 3 image buttons on a web page, and the buttons, (its either one or two) , will not load when i run it. and i have to close the browser and run it again. theres a 50-50 chance that the buttons will actually appear. Any idea what's causing this to happen? The pictures are in png format. and i saw from this website that I should change "Causes Validation" to false? What does it mean? Image buttons (from left to right):
Reigster - Back - Reset.
On my login page, i only have one image button which is Login and its always there. btw, im using visual studio 2005 =)

Have a look at below link. In that page if you mouse over on any thumbnail image a div opens with that image details with larger size. But there is a point to notice usually when an image gets downloaded in the browser we see that the image loads in parts from top to bottom. In this case the whole is loaded but in blurred state and gets cleared after fully downloaded.

I just wanted to know how this is achived? Does it require to code something or it is any javascript or dhtml?

I have an unknown number of image buttons inserted into a Placeholder at runtime during a webpage's Init stage. I would like to use a single event handler routine in C# language to determine which control was clicked and process any one of them differently. How do you create an event handler to process whichever image button that is clicked?

I need a control which can hold an image and two radio buttons, like the one we have when we upload a pictures on fb / orkut. 1. Image 2. Delete radio button. 3. Cover radio button. [Set this image as cover of album]
i have created a user control with these three things. On my aspx page on click of a button i need to add this user control. Means, user will select the image using FileUpload and when he clicks on the button this user control should be loaded. I am able to load the control. Check the following code.
[Code]....
1> All images come on new line i want them next to each other.
2> How to detect which radio button is clicked as i have more than one images, and all have radio buttons.
3> How to capture click of radio button from aspx page?
4> If there is some other way to achieve this let me know.
Searched on google but could not find a solution for this.

Got a problem that I spent all last night working on and still couldn't get it. I create this table dynamically. Then I have a text box and a button. You enter the name of a table in the text box and then click the button and that will call the MSSQL server and load the corresponding table. That works fine no problem.
Then I decided to create another table that lists the tables that are on the SQL server and create a hyperlink on each name of the table. So now all the user has to do is click the name of the table save the name of the table they clicked in the querystring and it will call the same procedure as the button. I'm getting a Findcontrol error that's telling me that two id's have the same id's when I click the hyperlink and then try to load through the button. It's duplicating the controls. I've tried clearing the viewstate, and session states and that still doesn't work. Has something to do with how hyperllinks and buttons work.

I have had a project called Articles and the project complies fine. I have it running as a seperate site on my machine and it works like a charm under IIS7. When I start the project from VS2010 in debug mode (by pressing F5) it lands on a page that says: "Parser Error Message: Could not load type 'Articles._Default'."
I i however change the path in the browser from [URL] Home it works fine again, indicating that my routing table is bust but it was working yesterday and I did not change any route, The error page also says: "Please do not delete this file. It is used to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request to the server." That idicates to me that it went to default.aspx...right?

I am trying to load the following JS method:
<script type="text/javascript">
function initialize(lon,lat) {
var myLatlng = new google.maps.LatLng(lon,lan);
var myOptions = {
zoom: 14,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
}
</script>
In my code behind in VB.NET I then want to load such as:
initialize(53.349803617967446, -6.260257065296173)
I need to load in code behind since I have to get the longtidude and latidude from DB.

I have a piece of inline java script which is within an AJAX updatepanel. The code works perfectly on 1st load but not when the updatepanel is updated.
My script is as follows:
<script type="text/javascript">
var flashvars = {};
flashvars.galleryURL = "Photo_gallary/personal.xml";
var params = {};
params.bgcolor = "000000";
params.allowfullscreen = true;
params.allowscriptaccess = "always";
swfobject.embedSWF("Photo_gallary/simpleviewer.swf", "flashContent", "100%", "250", "9.0.124", false, flashvars, params);
</script>
As this is not a function how do I put it in the ScriptManager.RegisterStartupScript - which is I think what i have missing.

I'm trying to create a list of image buttons dynamically, but I'm having trouble displaying the images. I'm using the Directory.GetFullPath method, but I don't think its the right thing to do.I've viewed the page, and the image path is showing as
'd:Hosting6238630htmlPropertiesCedarsext%20front.jpg'. I know this isn'r right and that it needs to be something like www.annereevelettings.co.uk/property/images..., but the question is, how do I do it?The page can be seen at the following address
www.annereevelettings.co.uk/property.aspx.

I'm working on an ASP.net web application. I'm getting errors on some of my pages where I get runtime JavaScript errors. I've narrowed the problem down to a single ASP Menu control on the master page. I created a blank page with just the ASP Menu control. The ASP Menu control is bound to Web.sitemap. The page intermittently gives runtime errors. However, if I refresh the page, the error may or may not appear on any given page load. Sometimes, it works; sometimes, the browser throws runtime errors when loading the page or when I mouse over the ASP Menu control.
When I catch the error in Visual Studio, the message is "microsoft jscript runtime error 'sys' is undefined". When I Google for this message, I find that it is usually associated with AJAX. However, the ONLY thing on the page is a single ASP control. There is absolutely no Javascript on the page except for what gets generated by the .net framework. What could be causing this problem? UPDATE I've found out that my environment actually has load balancing with a web farm of three servers servicing the URL. When I access the application on any one of the servers individually by IP address, everything works fine.
To clarify, I understand that when a user hits the public-facing URL, it resolves to x.x.x.1. x.x.x.1 is the address for a switch which routes the request to either x.x.x.2, x.x.x.3, or x.x.x.4. When I use the public-facing URL, I find that some of the axd file requests are intermittently rerouted to Error.aspx! WTF? I'm told that this is the result of a security feature that is meant to protect me from cross-site scripting and other assorted bad stuff. What can I do? Update After taking out some error page auto-redirects, I get a more meaningful error message: ASP.NET Ajax client-side framework failed to load.

I have a search textbox and two image buttons on a page I created with ASP.NET.
When I look at the page with either IE8, Google Chrome or Opera, the textbox does not align with the two image buttons. The buttons appear higher than the textbox and I can't tell why.
Here is the key markup:
<div id=searchbar>
<div id=Panel1
onkeypress="javascript:return WebForm_FireDefaultButton(event, 'btnSearch')">
<input id=txtSearch type=text name=ctl00$txtSearch>
<input id=btnSearch title=Search src="Test_files/search.png"
type=image name=ctl00$btnSearch>
<input id=btnAdvanced title="Advanced Search" src="Test_files/adv.png"
type=image name=ctl00$btnAdvanced>
</div>
</div>
NOTE: I realize there are a few strange things here such as no quotes around the ids. But there ARE quotes around them in my source. The above snippet is from saving the content from IE and it made a number of changes to the markup.
I also posted the same code at [URL} if anyone would be willing to take a look. The issue is with the search controls to the right of the black bar near the top.

3. if the user is happy with the preview then click the GO button to load the image to the Image folder.Does anyone have any good examples or sample code of how to do this?

watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

I'm still a basic user of ASP.NET and i'm trying to figure out how can i use the FileUpload control to give an uploaded image to the Image control.
The FileUpload control doesn't have an OnClick() event so when i hit Upload i don't know what happens with the uploaded file in the back.
what i'm trying to do is choose a file with the FileUpload control, preview it in the Image control and then save it in an SQL Server 2008 database in an "image" field.
