to fetch data to popup control dynamically I used webservice [WebMethod]public string getIssueDetails(string contextKey){ } But before that I set ModalPopupExtender1.DynamicContextKey = "1_1_60"; in code behind.But problem is in webmethod "contextKey" is getting passed as null.
I am trying to use the Slideshowexternder control with a contextKey that I've set from a query string. I set the contextKey in the default.aspx.vb Page_Load as I've read in other posts, but I am still getting an error:
The server method 'GetSlides' failed with the following error: System.InvalidOperationException -- Invalid webservice call, missing vaule for parameter: 'ContextKey'
I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
I wantto show up manually a ModalPopupextender without its TargetControlID assigned to anything. Thus I dont need a button or linkbutton that triggers to show it up.
I put a hiddenfield and attached it to TargetControlID and I can call ModalPopup manually by its show() method.
so why should I have to assign TargetControlID ? I dont wantto use a useless hiddenfield to attach as its Target.is there any other Ajax Control Modal Window that no need a Target ?

I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel { //Members: public Gallery _photo { get; set; } public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
and I am calling the webmethod by javascript like this [Code]....
The result is, I get the error function running and I get "undefined error" alert.Am I calling the procedure correctly? I put a breakpoint on the webmethod and it.
I've a problem: I've a GridView, with a folder structure, and an asp.net checkbox for each row in the gridview.Now, when the user clicks the delete button, it should delete all the folder entities where the user checked the checkbox.The problem is, there may not be a postback...So I used to use findcontrol in an ordinary asp.net button codebehind, but in a webmethod, it's impossible to access the page object, because WebMethods need to be static...Now I tried ctype(httprequest.current.request.handler,page) but that doesn't seem to work...
How can I get the page object to use findcontrol ?
I have been struggled for a day without success. Also I am not sure is this possible, since I am not too familiar with Javascript. let me know is there a way to fix my problem. Here is my problem:
What I have is a datalist and at each row it contain an UpdatePanel and inside the UpdatePanel there are a button, a slideShowExtender with related controls and a hiddenField. The hiddenField stored a second contextKey value. At page load time the default contextkey already assigned to the slideShowExtender. What I want to achieve is when user clicked the button the slideShowExtender will switch the Contextkey with the hiddenField value so that the SlideShowExtender will display a new set of images.
So far I can make everything work as I want with server side function, which executed when the button onclick. However this will generate a whole page post back, which I want to avoid. So I was thinking of using client side Javascript to do the contextkey assign and then update the updatePanel, but I am not too familiar with Javascript so I can't get it working :(
I have the following web method , no success on return a correct Json format.
[Code]....
GetAll() return list of type "Company" POCO classes.
The web method complaint type "Company" could not cast to object. However I could not just return the Company type because client side Json only accept its 2 properties -"CompanyName", "ID" and I want to keep it that way.
Of cause, I had tried create a CompanyDTO which only have those two properties, but same error - "Unable to cast object of type..."
How should I modify in my web method to make it able to return a list of partial "Company" type in Json format?
i am using autocomplete extender for three textbox.i want to pass the first two textbox value as a parameter to the webservice.How to do it using javascript?
I have a slideshow extender, I will change the slideshow extender's contextkey value by a button click event. So that after button click the slideshow will display different set of image. Originally with postback everything work fine, but I don't want the whole page to refresh.
So I put the slideshow extender inside an updatepanel with triggers target the button click event. Now the whole page didn't refresh and the slideshow extender's contextkey value did change (same code as before) after button click event. However the image set on the slideshow didn't change.
I think I am missing some sort of slideshow extender reload or refresh call but I am not sure how to do this? I didn't see any related property with slideshow extender...
I have a problem with 3 cascading drop downs. They are on a content page, so I have a Master Page as well. They work just fine but once the user saves the data and then comes back to the same page, I would like to show them what was previously saved. How can I pre-select items in the drop downs that I get from my SQL server db? I tried jquery, javascript, vb code behind and no luck so far. I'm sure i'm doing something wrong. Here is my code:
I've been trying to send my webservice a contextkey for the first drop down. When I debug the webservice, and I manually enter a context key, i get the correct values back with the value that equals my context key having <isDefaultValue>True</isDefaultValue>.
Aspx page:
[Code]....
WebService (part of it that gets data for my first drop down):
[Code]....
[Code]....
Javascript (tried to set the context key here)[Code]....
