I am writing a ASP program which I am going to run on an IPAD. Created a numeric keypad using buttons. Click a button and it adds the value to a textbox. textbox.text = textbox.text + "1"
Having some delay after each button press. I think this is due to postback happening with each keypress.
Is there a way that I can click a button...have it add the value to textbox.text and not do a postback? In other words do everything on the client side. It is my understanding you can run a Java script on client side but I don't know much about java at this point.
I have an Mobile web application. In my application i have Link Button control and Drop Down list control. These controls are not working in BlackBerry devices. Does any come across this problem? Can you give me better solution for this?Iam thinking to implement javascript for DropDownList control?
I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.
I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
I have an application that works perfect in IE and FF but when opened in iPhone Safari the checkbox checked and button onclick functions do not fire. I have looked all over the web for the last few days and could not find a solution to this very frustrating problem. I hope someone has encountered this before and knows of a fix.
I would like to know if the normal procedure for creating text files would work the same on a mobile website?
1. I would like a text file created on the server (not users pc) when user clicks a button on the web page. 2. How do I refresh an image every few seconds, only the image not the whole page.
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I have user mobile image control in object list and bind image to that image control, now i want to resize my image means i want to give height and width to that image control how can i do that I have write below code:
I tried to use the asp.net fileupload control for uploading a picture or music file, from blackberry device to server. But, What happened is ; the file is uploaded , ie, the file is created with 0 bytes in it. That is, file is actually not uploaded. Since blackberry browser doesn't support other fileformats, the device contains only .png & .m4a fileformats in its samples. I have used these sample in blackberry for uploading. The same has occured in the case of .m4a files also... Why is it so...? One more thing... The blackberry browser which I am refering here is the blackberry browser simulator, bold 9700.

wanted to know what is the easiest way to interface a mobile phone device with an online system. I have literally NO knowledge in this domain. However, I am brainstorming on possibility of an online application that will allow me to backup my data in nokia set 3110 such as my Address book in the application and restore it. This I want to achieve without connecting my phone to any PC. I am thinking on some way to achieve this by leveraging mobile phone line only. I beleive it may require my application to connect to mobile phone through mobile phone network. Currently my mobile phone line subscriber is offering Address Book backup/ restore service with some charge. I want to see if I can replicate similar features. I would really appreciate if you can give a direction to my random thoughts.If anything is not clear then please feel free to inquire. I look forward to your kind response.
I have website home page which my client can view well on his blackberry mobile phone but I have link buttons on that page which redirect the users to other pages ..just Response.Redirect ............simple code.... but when he clicks on the link, it requests for enabling javascript..I do that but the home page just does a postback. Links are not working on cellphone........... on regular website they are working fine.
I have a url whose query strings are concatenated based on selected items on a form, I need to do a post to this url, but an imagebutton control has to be clicked for the post to occur. I put the PostBackUrl property of the imagebutton inside the event of the image button, hence causing it to be clicked twice before eventually posting the url... but i really need to click once but this aint working. I know why its clicking twice, tried calling the url with javascript but it wasnt working.
When I click the button to open the modal popup it shows the popup but then continues and forces a postback causing the page to reload and the modal popup to be hidden again.Here is the markup for the control:
In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
Im wondering how to get a label control that is in a header template in a datalist on an aspx page. I need the control text to change when the user checks a checkbox outside of the list on the page somewhere. I tried Itemdatabound, but I dont want to have to rebind the list everytime the user checks the box (lots of slow reaction time)
