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 am using Asp.net 3.5 listview control. In item_updating event I am using this code...
dim country as string = Dim country As String = e.NewValues("country_name").ToString.Replace(" ", "")
It's updating record correctly. for example if I update USA to USA 1 1 then it's updating like as it. But I want it to be USA11
All the date values on my website (whether from DB or returned by DateTime.Now) are represented in the format of mm/dd/yyyy hh:mm:ss AM/PM, even though the database values of the dates are not that way at all.I want to change the format of all the dates to dd/mm/yyyy hh:mm:ss without AM/PM.
How can I do that?
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'm using a CascadingDropDown in my page and I need to do the following things :
- Getting the list of elements in the dropdown
- Setting a specific value to the dropdown if it exists in the list
I am a total noob in webservices and javascript so I would like to do this in the codebehind but when I try to get the items of my dropdown, the only one returned is the one that is selected on the client side.
Is there a way to get the full list from the codebehind?
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.
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 ?
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'm working with a simple MultiSelectList on C#.
I just want to populate this MultiSelectList with some string values (not a pair such as <"Key", "Value"> just <"Value">) and set some selected items.
Here's my code:
IEnumerable<string> ubicaciones = new string[] { "NEGOCIOS", "TERRITORIOS",
"LOCALIDADES" };
IEnumerable<string> ubicacionesSelected = Ubicaciones.Split(',');
UbicacionesPermitidas = new MultiSelectList(ubicaciones, ubicacionesSelected);
IEnumerable<string> transacciones = new string[] { "CARGA: ACCESORIOS",
"CARGA: EQUIPOS", "ASIGNACIONES", "DESINCORPORACIONES",
"PRÉSTAMOS", "TRASLADOS", "SALIDAS" };
IEnumerable<string> transaccionesSelected = Transacciones.Split(',');
TransaccionesPermitidas = new MultiSelectList(transacciones,
transaccionesSelected);
However, is not working... (it shows all the values on the MultiSelectList but it doesn't show any item selected) what am I missing
i am creating inintalizing a viewmodel with the following code in an create action;
[Code]....
the class applications is a LINQ to SQL Class and it has a property called VacancyID.
I want to default this VacancyID to '3'. From within this Action..
i have a usercontrol with two public properties
public DateTime fromdate
{
get;
set;
}
public DateTime toDate
{
get;
set;
}
I am setting this values in my code behind. After setting the values i want to reload the usercontrol so that it fires a get method which will use these dates ...how will i reload the usercontrol
Not sure if this falls under security but I figured since its about logging in it might. Anyway. I would like to know if my approach is good. I have set up a login, the Login method is under the User Class which uses validation to my own database (not ASPNETDB). I would also like to set values to that user to use on each page such as a simple label on the home page that says "Hello [UserName]". Code is below, should I separate the User values into a different class? Also once i go to another page (called Home.aspx) I would like to set an ASP Panel to have the username in it. I created a new instance of the User class in Home.aspx but unsure what I would need to go to get this to work. Should I have some LoadUser method after a successful login?
View 1 Repliesi have a page where i have a search area for users and a blank table. When a user performs a searcg,im creating in the cs the rows for the table and adding in the cells textboxes with values from DB. The textboxes ID´s are also being retrieved from the DB. Then, the user can change values from the textboxes. I also have an asp button that´s supposed to save the changes BUT i cant manage to persist the ids and last values between postback. Ive tried something ClientScript.RegisterArrayDeclaration but the array comes up empty. Then i used a hiddenfield but does the same trick.
what am i doing wrong?I add the hiddenfield,i try to add all the controls ids to an array but seems impossible,and there is no way i am getting the last values in another array. Im loosing everything between postbacks, but if i manage to save these ids and values, ill re-make the table in a sec.
I have a form with a checkbox list, the values of which are value = "1" value = "2' ...etc (amount of boxes not fixed). These values correspond to an id field in a database and are stored when a new user is entered. When reloading this info I want to populate the checkboxes according to how the user originally checked them.
What is the correct way to do this?
while (reader.Read())
(
i = Convert.ToInt16(reader["Id"]);
CheckboxList1.Items.FindByValue[i].Selected = true;
}
doesn't work....
I have some user controls which have properties which need to be set from a form on the page
<uc1:MyPlugin
ID="MyPlugin2"
runat="server"
Property1="Hi"
Property2="0" Property3="<%=Property3%>"
Property4="<%#Property4
%>"
/>
Property3 and Property4 anre both public properties of the page I am on and the user control
Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)
I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over
I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
I am trying to build a web user control and set some default values for its properties in the code-behind like this:
[DefaultValue(typeof(int), "50")]
public int Height { get; set; }
[DefaultValue(typeof(string), "string.Empty")]
public string FamilyName { get; set; }
[DefaultValue(typeof(Color), "Orange")]
public System.Drawing.Color ForeColor { get; set; }
When I add the user control to the page and call it without any properties:
<uc1:Usercontrol ID="uc" runat="server" />
the default values are not set and every property is 0 or null.
Background: I open a page that has a detailsview control using Accessdatasource. It is automatically opened with the row I want to update as I get there by passing the key as a URL parm. The update works for all fields except 2 template fields I added. I added a field for update date and updated by which I want the code to populate in the code behind so the user does not enter it. I have the same login on another page using an insert and it works fine. I cannot figure out what is wrong on the update and I tried everything. The code behind is in the OnItemUPdating event. code behind:
protected void set_update_date(Object sender, EventArgs e)
{
TextBox tbdate = (TextBox)DetailsView1.FindControl("TextBox_update");
[code]...
