AJAX :: Alternative To Postbacktriggers Or A Method To Achieve Result?
Feb 1, 2011
i have just found that i cant create postback triggers on the fly (i had a function that runs onclick that creates buttons and postback triggers)
so i need an alternative or a method to achieve this
what happens is onclick of a button, updatepanel1 is updateded and depending on what button you click in panel1 more buttons are added, these buttons that are added also have an oncllick event that should update a wysiwyg in panel2 with content
heres my code below, if anyone has any ideas or knows of other methods to get this to work it would be great
I am trying to freeze my gridview header for last 2 days and got this link and many other links too provided to me on Stackoverflow as well as from googling. This worked fine when i used it on IE 6,7 and under compatibility mode in IE8 but in normal mode, this code is not working.
This line is giving me an error. I want to implement this functionality.
I have a table with 4 columns: ID, signId, storeNum, quantity with ID, SignId, and storeNum as composite primary keyif storeNum is -1, that means the quantity is the default quantity. If a store has a store-specific quantity, the storeNum is this store's number.
I need to show all rows that have specific quantity for a store, and all rows that have default quantity and of which the store does not have store-specific quantity
currently I use table-value function with storeNum as parameter to return the list. first, I get all rows that have specific quantity for a store; then, I use cursor to loop through all rows that have default quantity and check each row if the store has a specific quantity. It takes 9 seconds to run the function for a store.
The function is called within a stored procedure, which in turn is called by a function in a class, which in turn is called by a aspx code behind file. It takes about 20 seconds to load the page. 20 seconds to load a page is too long. I am trying to improve the performance.
I wonder if there is an alternative method to the cursor to get the second part of the list.
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?
How can I achieve hover effect for the ajaxtoolkit combobox. I just need an outline for the entire combo i.e. outline for combo-textbox and combo-button when hovering over the combobox otherwise it should return to the normal outline color.
I could only get the hovering effect for combo-textbox alone and that too an outline creates at outer of the existing combo-textbox outline.
In my MVC view (page) having one link button while clicking the button I need to refresh the data in two div. I have converted my link button to AjaxLink button ie
<%=Ajax.ActionLink("AjaxRefersh", "Index", new AjaxOptions { UpdateTargetId = "div1" })%>
It's providing option to give one div to refresh but I want to refresh the data in two div. Do I able to achieve this through AJAX.
I build website with asp.net and c# .I have the following method
public List<string> GetAllNameDoc(List<int> ids) { List<string> Names = new List<string>(); foreach (int r in ids) Names.Add(GetNameDoc(r)); return Names; }
I want to view the result of this method in DataList or Listview or Gridview component.MayBe the Kind of data source of component is object But the problem How can I pass the parameter "ids" into these comonents. I try
I have a page with a ScriptManager, a generic HTML drop-down list (<select>), and an UpdatePanel. The UpdatePanel contains a PlaceHolder (for now). During Page_Load, a number of user controls are added to the PlaceHolder (really, it's several instances of the same user control). The number to add is not known until the page loads, so they do need to be loaded dynamically. The drop-down list is populated with the same number of menu items, and there is javascript on the page also (using jQuery) to show only one of the controls at a time depending on the state of the drop-down list.
Each user control has two buttons that should generate an asynchronous postback, a drop-down list that should generate an asynchronous postback on a change in selected value, and a button that should generate a synchronous postback. If I was not generating the controls dynamically, and if there was only one control, the structure would be something like:
[code]....
Of course, all the controls inside the ContentTemplate would actually be part of each user control.
Adding the triggers on the server side does not seem to work because no ControlID seems to the UpdatePanel find the relevant controls. I can use either the control's ID or the control's UniqueID, and it does not work, and I get an error along the lines of
A control with ID 'ctl00$ContentPlaceHolder1$ctl01$asyncButton1' could not be found for the trigger in UpdatePanel 'myUpdatePanel'.
So, I wonder if I need to register the triggers in the client instead using ASP.NET Ajax. I found this page that basically explains how. However, I do not know how to get the EventName taken into consideration. The examples I have seen so far have merely been adding button clicks, but I don't know how to handle the SelectedIndexChanged event from the DropDownList.
Are there examples out there I have missed? It doesn't , of course, that the method in the link I gave appears to be "unofficial," so I don't see any MSDN documents on the subject.
I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer) en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams) en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters) en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams) en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
In my Application I am using one Modal popup extender. I have one Grid View with Item Template containing Link button. I want to set Target Control Id of Popup extender to link Button of the Item Template. As it is inside the Item Template I can not access it directly in the page.
So Is there any alternative to achieve the same functionality.
I have this ListView that has a Drop Down List.Everything works fine (I think/hope) except that the drop down list are not showing its result correctly.This is the code.

The code behind consist of the page_load and the ItemDataBound [Code]....
I'm having a problem with my Linq to XML query. I'm getting the result data I want, but it's nested so deep that there must be a better way.Here is my XML:
[Code]....
I'm trying to get a list (simple string[]) of all Item IDs where Category Names contains "Other".Here is my Linq:
[Code]....
[Code]....
Here is a snapshot of my result from Visual Studio:The results I want are there ("item100", "item400", "item500"), but buried so deeply in the results var.
i have a web service that i use for the AutoCompleteExtender, let the below code show you what i'm trying to do: [Code]....
this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?
I am writing an application that renders a list of "Job" objects from an AJAX JSON response.
What is the best way to Render the markup from the returned data. Now I'm pretty convinced that its a bad idea to generate HTML markup on the server side and return that from the AJAX call. From experience it makes the HTML hard to maintain and re factoring the content is a nightmare, so I am returning a collection of Job objects as JSON.
The question, then, is how to render the HTML based on user input? I've seen some examples of having your markup template on the page then use JQuery to clone it and populate with the relevant data the insert it into the DOM.
The problem with this is that the template contains visible content (images and suchlike) and the application needs to degrade, so I have a repeater on the page that the severside code and populate on page load if JS is not available.
I have a client side code that creates an AJAX request to the server (using jquery). My problem is that one of the json results called 'name' gets spaces appended to the value.
For example: In the DB the value is "Hello" but when i get the request back using ajax it comes out as "Hello "
It is ALWAYS the one value that gets spaces appended, even on calls to different functions in the web service. Ive tried changing its name on the AJAX response, but the same thing happened.
Ive gone and ran queries directly against the web service by navigating to its address using my browser, and executed the query manually, and it comes back properly ("Hello").
Ive also tested this in IE, FF, Opera, Chrome and using different computers with the same results.
I don't see a property that would help define the location where matched items should be displayed. I have a strange behavior where if there are multiple matches, AutoComplete extender displays the list of matches nice right below my TextBox. However, if there's only one match, it's displayed some 30 or so pixels above the TextBox. Strangely, I find myself hitting the up arrow key because the suggestion is displayed above but looks like the expected behavior is down arrow.
