AJAX :: Tab Panels Causing Undesirable Mark-up Reformatting?

Sep 15, 2010

I am using VS 2010 and making extensive use of tab panels with gridviews inside of each. I very often am required to reformat the whole document as it seems that the gridview mark-up gets completely reformatted in one continuous line. In the act of reformatting unwanted things get inserted such as linebreaks. When I was using VS 2008 this behavior was even worse. Does anyone have a suggestion to fixing this issue? I am wasting time because things are changing visually and tested work is getting automatically changed.

Feb 28, 2010

Is there a way to give the selected range of a SliderControl a differrent color/image?

heres an example from Telerik.

As fare as I have worked with the Slider and MultiHandleSlider i dident find a way to create a slider looking like the one above (again: i need the selected range in a different color then the rest)

I tryed creating a MultiHandleSlider with only one slider, but as an effect the style for the part between the sliders is not used.

The normal Slider control has no option to create the wanted look

So how to create a slider with marked selected rang using the ASP Toolkit?

AJAX :: Collapsible Panels With Extender

Jul 6, 2010

I have 2 collapsible panel. The first panel is expanded by default and second panel is collapsed. When I insert a user control in the first panel (about 650px height) it displays it but the content overflows into second panel header. I have autosize to none and height to 0px in the cssclass.

The content section in panel is not expanding to fit. However if any place any amount of static text it works perfectly. Also when I collapse the first panel the rest of the panel is disappearing when an user control is used. Am I missing something. The same problem when I tried to used ajax accordion

AJAX :: Use Collapsible Panels With Nested Repeaters?

Oct 8, 2010

I have a page that has 3 nested repeaters. For the first two repeaters, the repeater's ItemDataBound event binds the next lower repeater. This works fine for the data that I have, but causes a large amount of data to load all at once on Page_Load. Is it possible to use collapsible panels with nested repeaters in such a way that the data only loads when the user clicks a particular linkbutton?

Javascript - Validation Using AJAX Without Update Panels

Dec 15, 2010

I'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:

1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.

2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.

3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.

Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?

AJAX :: Disable Tab Panels On Page Load

Feb 24, 2010

I'm using ajax 3 tab panels on my web page, whenever my web page is loaded i need to disable rest 2 tabs (to grey out with no click events).

when i tried to do this from server side, the tabs are completely hidden instead of disabling. My actual requirement is to use tab container as asp wizard control.

i'll be having form fields in my first tab with submit button, when the submit button is clicked, then the disabled second tab will be enabled and in the the second tab when submit button is clicked the third tabpanel needs to be enabled just as a wizard control.

i can use wizard control but, i'vent found any styled asp.net wizard control. How can i disable rest of the 2 tabs when the page is loaded.

AJAX :: Modalpopup Displaying Behind Panels Randomly?

Oct 7, 2010

I am working on a project at work and have been trying to implement the modalpopup extender. I have it set to display when invalid criteria is entered and the user tries to save the item. The problem that happens is that it will display correctly for about the first 3-5 times, but then after that the entire popup (messagebox/background) displays behind the content behind all the content, which are within panels. I have tried changing the z-index amongst the popup to something really high and keeping the panels' z-index very low, yet it still does not seem to work.

AJAX :: Update Panels, Repeaters And Lists?

Jun 3, 2010

I realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.

AJAX :: Detecting Cause Of Slowness In Update Panels?

Jan 27, 2010

I have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.

If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.

If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.

I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.

AJAX :: Gridview With Newsted Update Panels Slow?

Mar 19, 2010

I have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.

AJAX :: MultiHandleSliderExtender Not Causing Event Trigger?

Feb 4, 2010

I created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:

The code is as follows:

[Code]....

[Code]....

[Code]....

The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.

Now when I add another sliderextender below it for a different value, the code throws an error:

Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

I found this example on this site and tried implementing it but to no avail.
