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'm attempting to hook up multiple DropDownLists to a single SQLDataSource, but I want the SQLDataSource to return different rows depending on which DropDownList it is populating.
Say I have a table full of names (we'll call it TABLE_NAMES):
[code]....
....and I have two dropdown lists, one with a list of person names and one with a list of dog names.
Is there a way to link up each of these dropdown lists to a single SQLDataSource and use the SelectParameter to differentiate between which records I want returned for each dropdown list?
To make matters worse, these dropdown lists will appear within a GridView control....so there will be multiple instances of each dropdown list depending on how many rows there are in the GridView.
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:
[Code]....
and to set the value in the code behind my Page_Load has
[Code]....
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..."
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.
I have three ListBoxes each representing a single field database table. They are presented side by side on the ASP.NET page. Is there any way to group them so that only a single item from any of the boxes can be selected at a time?edit - ie, if item 3 in box 1 is selected, selecting any item in box 2 must unselect it
View 1 RepliesI'm trying to solve an issue in an elegant way. The problem at hand is I have 2 aspx pages (I'll call then Page1.aspx and Page2.aspx).
Page1.aspx contains an AJAX tab control with 3 tabs (I'll call the control Tab1). Page2.aspx also contains an AJAX control with 3 tabs (I'll call the control Tab2).
My question is, is there an elegant way to have a hyperlink on the second tab of the Tab1 control that links to the thrid tab on the Tab2 control? And, is there a way this linkage can be represented as a web address (example : http:\someserversomeappsomepage.aspx???TabControlIdentifier,???TabNumber.
The current methodology we are implementing is to pass the TabControlID and Tab number as querystring values and the set the focus in the codebehind of the page. But the only way I can think of to implement this across multiple pages is to have all the receiving pages implement the same overriding class that handles the focus issue.
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'm having trouble linking a form view I have on a web page with a drop down list on the same page. Basically, what I need to happen is whenever a new selection is chosen from the drop down list, the details in the form view should also change to represent that selection's criteria.
I have my drop down list connected to SQLDataSource1 and my form view to SQLDataSource2, and these are populating as expected, it's just the problem lies when changing the selection in the drop down list - the form view doesn't follow what is selected.
does anything have to be added in the properties options of either the data source controls or the form view? For example, in the "Events" section, there is a "DataBinding" and "DataBound" selection item that can be used - should anything be entered in this to connect the two?
PS - Here is the code I have in the back end of the page:

i have a job application process where users apply for a job, in the admin section administrators want to be able to see which applications have not been viewed. Now i have one page which lists all the job vacancies and then users can click into that specific vacancy to see which people have submitted an application. This all works fine.
However on the page i display the job vacancies i need to make it so that if there are any applications within a vacancy that need viewing it appears in RED.
The two tables i am using are below:
tbl_vacancies
job_id
job_name
location
voucher
details
availability
region
date_added
tbl_applications
application_id
job_id
fname
sname
other_info
.
.
.
.
date_addedd
viewed
Now the viewed column is in tbl_applications table, the applications relate to a specific vacancy via the job_id.
So what i need to check is IF there are ANY applications where the viewed = 0, if so that means that there are applications that need to be seen, and i want this to appear in RED.
Now i tried this several ways i.e an INNER JOIN etc.. but the full list of vacancies won't appearing.
So i tried this:
[Code]....

This doesnt work at all. I have a datareader which runs through the returns, i don't get any errors, and the applications display correctly but when i use the IF to check it doesnt work..
How do I insert the selections made on several checkboxes into the WHERE clause of a SQL SELECT statement? The scenario is as follows: the user selects one or more checks in different check boxes to determine the rows to be parsed in a SQL table. Then the user clicks on a Submit button and the result fills a Repeater table. How do I do this, and how do I configure the button to launch the SelectCommand?
View 2 RepliesI have a horizontal menu control populated (in static mode: StaticDisplayLevels="1" MaximumDynamicDisplayLevels="0") from a site map.

I'm trying to link a detailview to a gridview. Both are using the same datasource control and it's coming from an Access database. Both are showing data. The gridview is listing products fine and the detailview is listing details of some default product (maybe the first). How can I configure the two so that when I hit my select button on my gridview that it populates the details into detailview with the correct data for the selected product?
View 1 RepliesI have 2 DetailsView controls- dvPerson, dvVehicle - that are bound to datasets at RUN TIME. When a person is selected in dvPerson, dvVehicle should filter to show vehicle info only for that person.
View 7 RepliesBasically I am using gridview to pull data (Question/Question ID) from our SQL server. I am trying to write a program that allows me to check certain rows and a button that sends the checked rows to a seperate form with placeholders.
Is it possible to program a button to send checked rows in gridview to a seperate form with placeholders and if so how would I go about starting?
I'll start by saying that it took me a very long time to find this bug, since it's quite elusive... The Repeater control in the following test case contains two runat="server" DIVs. Each one of them gets a TextBox appened to them through the ItemCreated event of the Repeater. Both of them have AutoPostBack=True, and TextChanged event wired to txt_TextChanged. However, only the TextBox from the first level properly points to the event on the postBack of the page. The second level TextBox also causes the postBack to occur, the its value does not persist in the VIEWSTATE as well as the event does not fire. Here's adirect link to the test case in a .zip file, as well as all the code. The project is built in VS2010 using Framework 4.

hyperlink linking to a file
My website is working but when I host it up, the connection are all screw up. Is it because my connectionString are all linked via SqlDatasource and is for local files only? Whats the coding that I need to put in so that my site will connect to the database via accessing the web.config or server?
