AJAX :: Multiple Updatepanels Are Independent Of Each Other?

Oct 9, 2010

I just want to make sure that I got this right. If I have two update panels, and updatepanel1 has 10 dynamic controls created from an external button that resides on the page by default.. and then i have a second button which also is on the page by default but is an asynctrigger to updatepanel2...

then when the first updatepanel1 is populated with dynamic controls, then when I click button2 to update the second updatepanel2 with some data, the dynamic controls in updatepanel1 wil;l still remain there right? but does it persist by itself on postback? And if so why?

because when I click button2 to update updatepanel2, it does a partial page postback. So when it does a partial page postback, does that mean it does not destroy updatepanel1's dynamic controls?

C# - Make Independent Update Panels?

Jan 19, 2010

As far as I understand UpdatePanels, they should be invalidated separately, i.e. triggerring one UpdatePanel should not touch the controls of the other panel. It does work so for controls outside of any UpdatePanels, however those which are inside ANY UpdatePanel are touched by triggering ANY UpdatePanel:

<form id="form1" runat="server">
<asp:ScriptManager ID="SM1" runat="server"/>
<div>

Is The Cache Independent For Each Host Header Set In IIS7

Dec 22, 2010

I have a site that dynamically loads website contents based on domain host name, served from IIS7. All of the domains share a cached collection of settings. The settings are being flushed from the cache on almost every page request, it seems. This is verified by logging the times at which the Cache value is null and reloaded from SQL. This codes works as expected on other servers and sites. Is it possible that ASP.NET Cache is being stored separately for each domain host name?

Date Or DateTime Object To Be Independent Of Page Culture

Dec 28, 2010

Dim strTime as String = FomatDateForSave("28/12/2010")
Public Shared Function FormatDateForSave(ByVal strDate As String) As Date
FormatDateForSave = Date.ParseExact(strDate,'dd/MM/yyyy', System.Globalization.CultureInfo.InvariantCulture)
End Function

I am expecting strTime to be "12/28/2010" .... But its getting converted to "28/12/2010" The thing is when the operation is performed by FormatDateForSave ... it converts it to "12/28/2010" But when it is returned it is again converted to "12/28/2010"

I have set the Date for Page.Culture to be "dd/mm/yyyy" and want the value to be "mm/dd/yyyy" to be saved in DB.

Forms Data Controls :: Filtering Using Three Independent Dropdownlists

Jan 28, 2010

I need to filter data in a View using three dropdownlists that are populated independently of one another. The items in the second ddl are not based on the items in the first, etc. Each ddl is populated using its own sql statement. I want to be able to use each of these dropdownlists independently of the other two, but I want the data that is returned to be based on the values already in the other dropdownlists when I make a selection change.

For example: DDL1 is populated with Horsepower values from its own SQL statement.

DDL2 is populated with Gallons per Minute from its own SQL statement, unrelated to what is chosen in DDL1.

DDL3 is populated with Diameter values from its own SQL statement, unrelated to either of the other DDLs.

I want to be able to make a selection from any of the DDLs and filter data based on the selection, and whatever the current value is for the other two DDLs.

I'm coding in C# and I think I may need to create a delegate and an event to listen for when the SelectedIndexChanged event fires on any of the DDLs. This is slightly more complicated than anything I've coded up to this point, I'm a beginner, and I'm not even sure I'm aiming in the right direction for a solution.

Forms Data Controls :: Create Multiple Independent Gridvews In Runtime?

Dec 27, 2010

I'm trying to create multiple gridviews for a number of individuals based on a selection from a dropdownlist. The user will select his choice from the dropdownlist and from there a query is run to find the number of gridviews to create. Each gridview will also have its own data to bind. I believe I have most of it, I just can't get the gridview to show up. My thinking is to create the labels, then insert a gridview, bind it, and then repeat the process all over.

Asp MVC Validation - Dependent Fields?

Jan 5, 2010

I'm currently trying to work through MVC validation, and am coming up against some problems where a field is required depending on the value of another field. An example is below (that I haven't figured out yet) - If the PaymentMethod == "Cheque", then the ChequeName should be required, otherwise it can be let through.

[Required(ErrorMessage = "Payment Method must be selected")]
public override string PaymentMethod
{ get; set; }

[Required(ErrorMessage = "ChequeName is required")]
public override string ChequeName
{ get; set; }

I'm using the System.ComponentModel.DataAnnotations for the [Required], and have also extended a ValidationAttribute to try and get this working, but I can't pass a variable through to do the validation (extension below)

public class JEPaymentDetailRequired : ValidationAttribute
{
public string PaymentSelected { get; set; }
public string PaymentType { get; set; }
public override bool IsValid(object value)
{
if (PaymentSelected != PaymentType)
return true;
var stringDetail = (string) value;
if (stringDetail.Length == 0)
return false;
return true;
}
}

Implementation:

[JEPaymentDetailRequired(PaymentSelected = PaymentMethod, PaymentType = "Cheque", ErrorMessage = "Cheque name must be completed when payment type of cheque")]

Has anyone had experience with this sort of validation? Would it just be better to write it into the controller?

How To Make Script Paths Inside User Control Independent Of Page Hierarchy.

Jun 3, 2010

My 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.

C# - How To Debug An Application That Is Time-dependent

Nov 3, 2010

I'm working on an application (a web application, asp.net and c#) which is datetime-dependent, so, based on the current date, it will launch forms for the logged user to fill in.

I've been thinking about how we're going to simulate real usage of the application, for debugging and testing purposes.

So I'm talking about replacing all those:

DateTime currentDate = DateTime.Now;

with something like:

DateTime currentDate = MyDateClass.GetCurrentDate();

And then I'll have a class:

public class MyDateClass
{
private DateTime _currentDate;
public DateTime GetCurrentDate()
{
// get the date, which may be different from DateTime.Now
return _currentDate;
}
public void SetCurrentDate(DateTime newCurrentDate)
{
// set the date to the value chosen by the user
_currentDate = newCurrentDate;
}
}

allowing me to set the current data, by invoking the SetCurrentDate method, for example, in the code-behind of a link button and a calendar input.

how should I exactly store the DateTime variable, throughout all the application? I can't work with the session in this class, right? Should I work with the Thread?

Forms Data Controls :: Dependent GridViews?

Mar 15, 2010

I have this "how to" type of question. I have a page where there are four gridviews. Now these four grids pull data from four different tables. The 1st grid retrieves data from table 1 with a where clause in it's query that comes from a hidden fileld value in the page. Till this things are fine. However, the 2nd grid has a dependency on the 1st grid and the where clause in it's query should be the data selected in grid view1. The 3rd depends on the 2nd one..and so on.

GridView RowStyle Dependent On Property Of Item Row Bound To?

Jan 19, 2010

I'm currently using a GridView and I want to set the CssClass for the Row depending on a property of the object that the row is being bound to.I tried the following:

<asp:GridView id="searchResultsGrid" runat="server" AllowPaging="true" PageSize="20" AutoGenerateColumns="false">
<!-- The following line doesn't work because apparently "Code blocks
aren't allowed in this context --> <RowStyle CssClass="<%#IIF(DataBinder.Eval(Container.DataItem,"NeedsAttention","red","") %>
<Columns>
<!--............-->
</Columns>
</asp:GridView>

Now I could simply handle theGridView's RowDataBound event and change the css class of the row there...but I'm trying to keep a clear separation between the UI and the page/business logic layers.

Database Dependent Caching W/ Multiple Databases/SqlServers?

Oct 6, 2010

I'm working in an environment where a single web application (running in a web-farm) dynamically connects to different SQL Server databases (possibly on different servers) based on user selection (this part is non-negotiable, unless you can gift me $1,000,000 and/or some kind of time altering device).

I'd like to cache some of the commonly used data from the database(s) in the application, such as "settings", and am looking for a best practice to use with the SqlCacheDependency class or a related database cache dependent solution (not opposed to a custom implementation of SQL notification or polling; notification is preferred over polling).

So far, I'm thinking of using a collection of SqlCacheDependency objects (one for each database) that can be referenced by connection string name or related key. So when the connection is changed to a different database, the cache can be requested/populated by a key of <databasekey>+<datakey> and use the appropriate SqlCacheDependency object (probably handled by a cache-managing wrapper).Or is it just better to take the hit and always go to the database?

Keeping one stylesheet for all browsers but having browser specific styles if any fixes are required. I know this can be done, i just dont know how.
