AJAX :: Use Javascript To Call A SliderExtender (textbox) To Update Its Value?
Oct 18, 2010
I am trying to develop two step size buttons + and - so that when you click either one, the AJAX SliderExtender will magically move itself by one. I have tried implementing the following functions:
here's what happens, I see that the BoundControl textbox works and it gets updated to 5. However, the slider still does not update to its new position. When the slider moves, a postback will occur. The Slider1 is the textbox that is the targetID to SliderExtender1 . The boundcontrolID is Slider1_BoundControl (textbox)
I've tried variations on CSS and layout (such as tables) but haven't been able to solve this problem. I've been able to recreate this with my simple example below on both Firefox 3.6 and IE7. When I load this page, the textbox blinks in for a second and when the slider appears the textbox will disappear. In the case of this example, the slider appears in the place where the textbox tried to load. In other examples I've created the textbox and slider load in different places but the textbox still disappears when the slider appears.
[Code]....
I realize this is an extremely simple example but I'm trying to narrow down the possible places for things to go wrong.
I am using a bunch of SliderExtenders to morph the ASP Textbox into a Slider control. This has worked great. However, I noticed that 1/20 times, occasionally, the sliderextender fails to morph the textbox. So the textbox actually appears during initial page_load. However, you can still drag the slider around because it is also rendered beneath the textbox.
A subsequent page refresh fixes this problem until some other time.
Second thing, this also frequently comes out more when switching between a javascript tab and an updatepanel.
I'm using a Ajax SliderExtender in a UpdatePanel. I set a BehaviorID and call $find('behavorID').add_valueChanged function in the $document.Ready. Everything is fine but when I press F5 and refresh the page, I lose the slider in a 1/3 (wtf) chance. If I set var slider = $find('behavorID'), it recognises slider is null.
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
I added a user control on master page and inside UserControl i add a link. and did some stuff on click of link.
Again i add another Content Page that is using the user control not the master page. Inside the table i add some textbox and save values in database . and the table is in UpdatePanel. and added ad trigger
When i remove the usercontrol entering on table textbox values works fine. and again i put the same user control the link button contol doesn't work for me.
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
I have a sliderextender inside a listview and there is a button that save the sliderextender values inside the listview. My problem is when i am trying to get the value of each slider i do not get the value set. My boundcontrol that i declare on the sliderextender changes but when i try to get its value its "" but there is a value displayed.
function SetScrollEvent() { window.scrollTo(0, document.body.scrollHeight);}
I update update panel from server side like below.
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e){ //HiddenField hiddenId = e.Item.FindControl("hiddenId") as HiddenField;Label lb1 = e.Item.FindControl("Label2") as Label; //Button bt = e.Item.FindControl("Button2") as Button;if (e.CommandName == "myclickevent"){ // your codes here...SqlConnection conn = new SqlConnection(constr);SqlCommand
[CODE] .....
I use repeater and repeater have button on button click i update the update panel. now where i have to call the javascript function so that it execute after update panel fully loaded. I want to call javascript function after page fully loaded.
Right now, the SliderExtender value (when dragged around) will cause a normal postback on TextChanged.
My situation is, the server side code would also like to dynamically change this slider value. When it does this, it changes the sliderextender value by javascript. However, teh problem is, when this happens, another postback occurs raising the OnTextChanged event when a postback occurs.So how can I change the sliderextender value from the server side withotu raising a postback?
I've tried to set autopostback=false, then set teh value, then setting it back to true but this wasn't workign in javascript.
I'm using SliderExtender in content of a Master Page.
It has a JavaScript function that is called in both $(document).ready and Sys.WebForms.PageRequestManager.getInstance() .add_endRequest() .
When I initial the page, the function is not active, it says " $find('BehaviorID') " is null, while other JavaScript function (without behaviourID) works smoothly.
But when I do a postback on the page. The slider function turns to available.
It seems the page didn't generate properly, miss a slider tag with class = "...BehaviorID..."
So I want to build a page with 3 sliders that are linked and limited to 100 total. So if the user slides the 1st slider to 100 then the other 2 wont move. Or they could do 50 / 25 / 25 etc etc...
So I need to limit each slider maximum based on (100 - the other 2 selected values) and I'd like to do it without a postback.
Is there a simple way to turn off form submit behaviour of the page when ENTER is pressed while I am focused to textbox? What I want to achieve is to call a web-service without submiting the page when ENTER is pressed in a specific textbox in my aspx page?
I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.
I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!
when i click on the textbox which is inside the item template of gridview then onclick event should fire and then call the javascript function but my problem is that there no onclick event option in item template's textbox

PROBLEM: So how would i update this using an update panel and timer. Currently when i do it the chart just disappears on update. I believethis is due to the fact that i am calling a dataURL. How would i get this to work javascript?
I have a page with an AJAX TabContainer and 4 AJAX TabPanels and have Save button. On a button click im calling javascript thats make ajax tab disappear why?
I have an updatepanel on the webpage and also the event UpdatePanel1_Load. After the webpage is loaded I will have the possibility to call the javascript function: "CallUpdatePanelLoad()" My question is how it would be possible to exectute the UpdatePanel1_Load in C# from this javascript function?
