C# - ASPxGridView - Simply Add Example Values With Only A DataSource Property?
May 19, 2010
I have a ASPxGridView. In it(for the uninformed) is only a DataSource property for telling it what data to load. My problem is that I'm simply trying to mock up an example and don't need to tie it to an actual database. How would I do this? I basically just want a few rows and some columns but since it only takes a datasource I'm not sure how to do it. Would ObjectDataSource be what I'm looking for?

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

I am currently trying to import a value from an SQL database and simply add it to another predefined value.
The problem I am having is that upon trying to add the two values together I am receiving a type mismatch error.
neww = 0
values = objRS1("Amount Including VAT")
neww = neww + values

I am developing a web dashboard under a deadline. We are interested in making a demo release before the dashboard has been fully developed. It does not currently have the concept of a logged in user.
The state of the web dashboard is currently saved into Session. All my classes are serializable, and I was able to set my SessionState Mode to SQL Server and write Session to a SQL Database. I would be able to use this to serve my purposes, but I have been unable to figure out how, if possible.
The goal is this: "Represent the saved state of the web dashboard as text and be able to load the state of the dashboard on another computer." The method to me was to write XML to a text file and be able to move that text file to another computer, point at it, and load my state again.
My issue with writing Session State to a SQL Server is that when the Session expires (browser closed/time out) I am unable to load the old data up onto the page. If there was a way to say "Take the data from session state _ and load it onto the page" I would be golden. As far as I can tell this isn't possible.

What am I missing here. I just want to pull the first one returned from row.detail in an MVC2 view, how would i do this without a foreach loop? This code currently works, but i just want the first one listed. I know this may be simple, but i am drawing a blank.
if (Model.App != null)
{
foreach (var row in Model.App.Instructions)
{
<input type="hidden" value="<%= row.Detail %>" id="ixd" />

I have a custom control that inherits from .NET's CompositeControl class. This control overrides the CreateChildControls in order to build its child controls dynamically. I need the page to post back after a couple different javascript events occur on the client side.
In order to accomplish this, I create two hidden controls on the page so I can set their values with javascript, submit the page, and read the values out on server side. Here's is the code I use to create these two hiddens:

As what other member said in this community, the data assign a public variable may be shared among users, therefore, how am be able to declare a property that will accept an array of values using List<string>? The variable will be use in about fifteen pages...if I am going to declare this on each of the page, this will result to difficulty in maintaining the code of my program.

I have a very simple user control with 5 radio buttons on it, and 3 properties (ID, RatingSetID, and Rating). On the initial load of the page they are on, the code acquires data and places the data into the 3 properties. However, when the submit button is clicked the page reloads and the 3 properties get reset to 0, they are in the !IsPostBack as well.

What is the best way to get a number of property values of a business object from the View to the Presenter in a WebFormsMvp page?
Bearing in mind this issue with DataSources: [URL]
Here is what i propose:
The scenario is, I have a business object called Quote which i would like to load form the database, edit and then save. The Quote class has heaps of properties on it. The form is concerned with about 20 of these properties. I have existing methods to load/save a Quote object to/from the database. I now need to wire this all together.
So, in the View_Load handler on my presenter i intend to do something like this:

this is about ASP.NET, ViewState, UserControls and loosing the values of my properties. It is an classic question by know, I know, and even though I have searched here and on Google for a resolution to this problem, I havent succeeded. On the contrary, the more I test different things, the less I understand it seems.
On top of this I am using ext.net and their so called DirectMethod's but I dont think that has much to do with this problem. There are numerous questions I have and I hope that this text will be fairly readable and understandable =)
The UserControl
I have a UserControl, Customers.ascx, that contains some Properties. The "most" important is *_CustomerId*. The _CustomerId is set in code-behind, in ext.net's "DirectMethod" like this (code below from the Page Customers.aspx):

I am working on a page whereby all the controls within the page get translated to another language.
This is handled within the master page prerender event and generally works fine.
However my page consists of a multiview control that is made up of 2 views. By default the INSERT formview is displayed so the user can enter form detials. This translates fine.
On clicking the save button the multiview active index is set to 1 and the EDIT formview displayed so as the user can update any of their details. This view does not get translated.
It would seem this is due to the controls not being available at this point in the page cycle or when this button event fires.
So i opted to do the translate process within the prerender event of the EDIT formview, and the method does have access to all the controls within this formview and runs after the master page prerender event. So all should be good.
However it seems that all th epage properties at this point in time are cleared. So the translation doesnt work. At the point of master page prerender i have verified they are populated with the values, but as soon as i hit the formview prerender all the page properties get cleared to nothing...

I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.
To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.
But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.
This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.

I am using Visual Studio 2010 and therefore have RDLC 2010 so developed couple of reports but when I run the project within developer machine and tries to export in Excel it works fine.

Verify that the file is not corrupted and is from a trusted source before opening the file."then it ask do u want to open anyway...when you select YES then it comes simply blank.

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.

The following action in my controller does not update the Model property which is bound by a radio buttons group (all are named "ListType") when the form is submitted. On the Edit.ASPX form, I used JQuery to reset the radio buttons group. When setting other type of input elements on the form to blank or checked=false, those Model properties are set accordingly upon submission. Does anyone know how to set radio buttons to unched state?
Also I am trying to get the SqlException to show up in my form where I have Html.ValidationSummary helper. My ModelState helper captures the know business rules violations, but I am unable to pass any SqlException and its Message property to this helper class due to unexected exception.

1: I have a .html file that has some markup with some placeholder tags.
[code]...
4: PersonInfo.aspx is literally empty since I am injecting html from code-behind.
When the PersonInfo.aspx is called the html-template markup with appropriate values in the placeholder will be displayed. Also there are chances I would like to send the final markup in an html email (though that is not part of the question as I know how to email).
Is this the best way to fill values in my html-template or is the any other better alternative?
Note: This is a very simple sample example. My class is very complex involving objects as properties and also my html template have 40-50 placeholders.
So code in my step 3 will need 40-50 Replace statements.

I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:
public int ContractIdx
{
get
{
return Convert.ToInt32(this.Attributes["ContractIdx"]);
}
set
{
this.Attributes["ContractIdx"] = value.ToString();
}
}
I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.
Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.
Where am I mistaken in my understanding? How should I change things to get this mechanism to work?
