View 2 RepliesMake Updownnumericextender User Control To Work Like Autocomplete One?
May 11, 2010I have a user control which encapsulates a NumericUpDownExtender. This UserControl implements the interface ICallbackEventHandler, because I want that when a user changes the value of the textbox associated a custom event to be raised in the server. By the other hand each time an async postback is done I shoe a message of loading and disable the whole screen. This works perfect when something is changed in for example an UpdatePanel through this lines of code:
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
The UserControl is placed inside a detailsview which is inside an UpdatePanel in an aspx. When the custom event is raised I want another textbox in the aspx to change its value. So far, When I click on the UpDownExtender, it goes correctly to the server and raises the custom event, and the new value of the textbox is assigned in the server. but it is not changed in the browser.
I suspect that the problem is the callback, since I have the same architecture for a UserControl with an AutoCompleteExtender which implement IPostbackEventHandler and it works. Any clues how can I solve this here to make the UpDownNumericExtender user control to work like the AutComplete one? This is the code of the user control and the parent:
using System;

using System.ComponentModel;
using System.Text;

{
currentInstanceNumber = CorpAjaxControlToolkitUserControl.getNextInstanceNumber();
}
registerControl(this.HFNumericUpDown.ClientID, currentInstanceNumber);
string strCallServer = "NumericUpDownCallServer" + currentInstanceNumber.ToString();
// If this function is not written the callback to get the disponibilidadCliente doesn't work
if (!Page.ClientScript.IsClientScriptBlockRegistered("ReceiveServerDataNumericUpDown"))
{

str.Append("function ReceiveServerDataNumericUpDown(arg, context) {}").AppendLine();
Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown),
"ReceiveServerDataNumericUpDown", str.ToString(), true);
}
nudeNumericUpDownExtender.BehaviorID = "NumericUpDownEx" + currentInstanceNumber.ToString();
ClientScriptManager cm = Page.ClientScript;
String cbReference = cm.GetCallbackEventReference(this, "arg", "ReceiveServerDataNumericUpDown", "");
String callbackScript = "function " + strCallServer + "(arg, context)" + Environment.NewLine + "{" + Environment.NewLine + cbReference + ";" + Environment.NewLine + "}" + Environment.NewLine;

}
and to create the loading view I use this: //The beginRequest event is raised before the processing of an asynchronous postback starts and the postback is sent to the server. You can use this event to call custom script to set a request header or to start an animation that notifies the user that the postback is being processed.
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(
function (sender, args) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.show();
}
);
//The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser. You can use this event to provide a notification to users or to log errors.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(
function (sender, arg) {
var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior');
modalPopupBehavior.hide();
}
);

How To Make Script Paths Inside User Control Independent Of Page Hierarchy.
Jun 3, 2010My website is organized in the following folder structure
Root
Pages
CustomerManagement
DepartMentManagement
Script
UserControls
Now i have a user control inside userControl Folder. I have to use a external js file. So i use it this way
<script type="text/javascript" language="javascript" src="../Script/slider.js"></script>
My understanding is that since both are under root so i have used a single .. Now what happens is that when this usercontrol is used inside DepartMentManagement it checks for script folder inside CustomerManagement as .. refers to one hierarchy above and script file is not found.Even using a ~ doesnot work.
I want to make this script path independent of the path where this control is used. I don't want to move script reference code to the page as control requires script mot page.
How To Make User Control Partial Classes Aware Of Controls Declared In The Base Class
Mar 5, 2010Do we have to do something special to have ASP.NET partial classes aware of controls that are declared in our user control's base classes? The partial classes keep generating declarations for controls in the base class which mean the controls in the base class get hidden and are null.
View 1 RepliesServer Controls In User Control Are Null When User Control Serves As A Base User Control ?
Jun 4, 2010I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
Web User Control With Javascript Used Multiple Times On A Page - How To Make Javascript Functions Point At The Correct Controls
Apr 12, 2010I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

View 5 RepliesWeb Forms :: Access User Control Properties In Another User Control
Nov 9, 2010I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.
What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.
I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)
How can I get the controls to fire in order and pass values to each other?

View 8 RepliesState Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
Web Forms :: Make 20 Min Countdown After User Pressed Button?
Feb 21, 2010First of all, I'm sorry if I don't describe my problem so well, English is not my first language. I'm working on a project where after the user has pressed a button, the button goes invisible and a label control should say "In 20 mintes you may press the button again". The problem is that if the user presses the button before the current hour is almost over, then he will be able to press the button again. The way I compare the time is by placing th current time, which the user presses the button in a sqldatabase table row for that user. This is my code for the moment for showing the user how long he has to wait:
DateTime TimeSincePressedbutton = Convert.ToDateTime(user.timeSincePressedButton); //value from database
TimeSincePressedbutton.AddMinutes(20.00);
TimeSpan d = DateTime.Now.Subtract(TimeSincePressedbutton);
int dd = Convert.ToInt32(d.Minutes);
int timeLeft = 20 - dd;
ValPointsTitle.Text = "In " + timeLeft.ToString() + " minutes you may press the button again";
and the code I have for comparing time with the time now, is to see if the user may press the button again (which I know is wrong, just cant figure out how to fix it, the reason I compare hour, day, month, year etc is because if the user doesnt show up online the same day, maybe he comes back after a couple of days, or next month, or next year).
if (timeLeft <= 0 && DateTime.Now.Hour == TimeSincePressedbutton.Hour || DateTime.Now.Hour > TimeSincePressedbutton.Hour || DateTime.Now.Day > TimeSincePressedbutton.Day || DateTime.Now.Month > TimeSincePressedbutton.Month || DateTime.Now.Year > TimeSincePressedbutton.Year)
{
//button becomes visible and the user may press it again
}
