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.
View 2 RepliesI'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.

I realize this is an extremely simple example but I'm trying to narrow down the possible places for things to go wrong.
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.
have a sliderExtender Control over textbox like this
<cc1:SliderExtender
ID="SliderExtender1"
BoundControlID="TextBox1"
TargetControlID="TextBox2"
runat="server"
Maximum="10000"
Steps="500"
Length="200">
</cc1:SliderExtender>
However, when I drag the slider the incremental is not 500. How to ensure it increase by 500 each small drag movement ?
On my page I have the code:

and to set the value in the code behind my Page_Load has

If leave the slider alone or change the value Label1 always says 110. I want it to say the slider value + 10.
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.
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:
document.getElementById ("Slider1_BoundControl").value = 5;
document.getElementById ("Slider1").value =5;
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'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.
View 1 RepliesI 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?!
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.
Is it possible to set a "not set" value for the SliderExtender? For example, I have a SliderExtender defined to take an integer value from 1 to 5. However, until someone sets it, I want the SliderExtender to return a "not set" value, and for the handle/rail to signify that it has not been set (e.g. handle/rail in a different colour). I have tried using the value "0", NULL, Empty, dbNull. In each case I either receive an error (invalid value) or the SliderExtender "cleverly" sets itself to the minmimum value of "1" I have tried the following...
When the usercontrol is initially loaded I set the rail to red colour using RailCSSClass, and set the TextBox to "0" - which is not a legitimate value because the extender expects an integer between 1 and 5. The result, upon initial loading of the usercontrol is that the rail is red in colour (indicating to the user that they need to set it) and the handle appears in position 1. All is reasonably well at this point. HOWEVER, if anything on the web page causes a postback, the SliderControl's TextBox sets itself (as expected, I suppose) to "1", and the TextChanged event fired - making it look as if someone has now selected a value. So.... can the SliderExtender/TextBox be made to "accept" a "not set", value by some other clever means - and to remember that "not set" value between postbacks?
I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?
View 3 Replies I have the modal popup come up for searching something. Inside the popup (panel) I have a txtbox and a search button. I enter text and hit 'search' and the results are shown in a listview within the popup. Now every row in the list view has a button "Select". I want to click on one of those buttons to select a particular value.
Now on click of the button(within the listview), I tried calling a javascript function and doing $find('mdlPopup').hide(); , which makes the popup dissappear. But somehow the debugger takes me straight to Global.asax.Application_Error() and doesn't even give me a stack trace to see wht the issue is. And over that, the popup looks dissapeared, but the rest of the controls on the page are not enabled back. Strange?
I'm assuming, that the popup doesn't close as intended and it errored out (which took me to Global.asax.Application_Error() ), and is not enabling the rest of the controls in the page.So my question is, how do I assign multiple buttons in a listview to the okbutton (or cancelbutton) of a modalpopup extender?
I need to show a popup when the user hover over a Listview item, for this I am using the PopupControlExtender which is placed inside the Listview ItemTemplate. The popup panel always shows inside the Listview item. How can I control the positioning of the popup panel to show outside the Listview ItemTemplate ?
View 4 RepliesI am having a listview control in my aspx page with name "vehicleListView" and i am assigning the datasource from js function. But when i took the listview control by using the following line
document.getElementById("VehicleListView"),
I am always getting "undefined"
Ho can i get the listview control id in javascript function.Listview control is in an update panel.
I have to assign the datasource of the listview control from js only.Because the jd function is getting the datatable from the C# pagemethod.
I have a UserControl with a ListView where I placed a button to upload files. I will like that button to be the TargetControl, however the modalpopup extender has to go outside the listview, because it does not work inside any of the templates, and then it does not recognize the button that is inside the list.I have tried putting ModalPopupExtender1.Show() in the button event but it does not display the popup.I have also tried calling the following script but gives "error: 'null' is null or not an object".
<script
type="text/javascript">
function popUpModal(){
$find("ModalPopupExtender1").show();
}

View 2 RepliesI have a usercontrol with listview control nested inside an UpdatePanel and Panel. Below is the layout:UserControl :: Panel1 -> UpdatePanel -> Panel2 -> ListViewUpdateMode is set to conditional. Panel2's visibility is initially set to false.In the containing page, I load the usercontrol and bind the ListView, turn on the panel2 and call the update method of the updatepanel (since action is initiated by an external button and not a child of updatepanel) which displays the rows successfully. However, none of the edit, select or delete actions execute the intended way. When I click any of those buttons, I can see the
UpdateProgress fine but the events seem to be not firing at all. Execution hits the PageLoad but not into any of those event handlers likeItemEditing, SelectedIndexChanging etc.
I have a ListView and Calendar on the same page. When somen selects a day on the calandar, I want the ListView to be refreshed with new data. However, when I go through the Calendar_SelectionChanged nothing happens until the next page refresh. The function does execute as I have verified through debugging. Going through the code behind everything looks fine, but the ListView just does not change. I can put a timer on the page with no code, and the ListView will not refresh on the calendar event, but does refresh when the timer click event occurs.
View 2 RepliesI have a ListView that does quite a heavy query. I don't want the user to have to wait half a second to a second for the page to load. I would much rather have the page load, display the theme and then have ajax make a call to the server to run the query and bind the listview while a loading icon is displayed.
The only thing i can think of is to use the sys.application.init handler to add some javascript that calls dopostback and passes a command name. I dunno... any thoughts? Anyone do this with aspnet/ajax with update panel? I guess im trying to bind an update panel without requiring a user clicking a button.
Does anybody have recent information on surmounting zorder problems with the PopupControlExtender? Web searches found a few comments that seem directly related to the problem I'm having, but no solutions... Most-suggested solution is to set the z-order to a high value on the panel containing the popup markup, but that is helping me (and didn't seem to fix the problem for others either). I'm using popup extenders within the EditItemTemplate of a ListView, and however hard I try I always end up with the other records in the listview (i.e. those using the ItemTemplate) overwriting the popup markup.I had high hopes that this problem might have gone away with release 40412 of the toolkit but it appears not

Does anybody have a working example of a cascading dropdown inside the insertitem and edititem templates of a listview? I have been working on this for a couple of days now with only marginal success, and I fear I will have to abandon work on this due to time constraints.
The areas where I'm having difficulty are:
I just have two dropdowns(dds). In the insertitem row, I am able to have the user choose from dd1 and set a value in dd2. This works fine, but the user must be able to go back and change dd1 and have the proper value set as a selected default item in dd2. I can't get this to work.
In the edititem rows, I'm having difficulty setting the selected value of the dropdowns when displaying the row to be edited, and am running into the same problem as above when the user changes a dd1 value - the dd2 value does not reset to the proper selected default item.
My strategy for the edit items has been to try to get elements from the dataset bound to the listview to flow to the web service routines as contextkeys. I then iterate through the data values to be displayed in the dd and if the value = contextkey value, then set its isDefaultValue to true when adding it to the list of CascadingDropdownNameValue items.
The solution needs to work in the real world. That means Master Pages, so any fancy javascript workarounds need to take this into account.
