I'm trying to inherit the GridView such that I can add a collection of filter properties which can be shown at design or altered at run time which would be like:-
Is there a way to do this in asp.net 2.0 GridView.
I need to bind a bunch of properties over my model entities. All of them uses the List<T> class. I already managed to write a model binder that can treat individualy types derived from that class, but i can't set the value of this property on the model. every time i check the model afer the bind process i see a list with 0 itens.
Here's how it runs.
After i post the values the model binder catchs up the types for bindingAt the custom model binder i check if this property is a List<T> typeIf it is then i perform the bind like it have to be, if not i let the default binder do the job.Finally i return the object binded. What happens next is the issue i've mentioned "i see a list with 0 itens" on the Model property.
Here is the code of Custom Model Binder:
[Code]....
Note: I'm working with MVC3 RC and Razor views.I've got this model:
[Code]....
I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:
[Code]....
What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.
I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.
There are some objects contained in each of those objects... for instance there is an Address object.
object.Address.Line1;
object.Address.Line2;
When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:
"A field or property with the name 'xxx.xxxx' was not found on the selected data source."
here is the requirement:
i have a lable a textbox, and two buttons(+ and - button) on my asp.net page.
so when i click on the plus button it should add the the whole collection of controls to the page(i.e. lable, textbox and two buttons). And when i click on minus button it should remove the collection.
This should go on.meaning whenever i click on any plus button the control collection should get added to the page.
I am wondering what will be the best approach to do it.
I'm trying to have a View where the user can add items in a collection without having to go to a new View (the scenario is a sort of CV site where the user adds info about work experience, skills, etc, and it would seem absurd to go to a new View to add each little thing).
So I have an edit View that shows a number of text boxes for the already added items, and there's an ajax call to go to a method to fetch the collection fresh if the user adds an item.
Here are the methods in question:

I have a list item collection. How to add this list item collection to a datatable.
The list item collection has the following fields:
Student Name, Maths Mark
John 20
Mac 30
John 35
I want to create a html table from the data table, which is grouped on the Student Name field.
I have an object with a couple of DateTime properties:
public DateTime Start_Date { get; set; }
public DateTime? End_Date { get; set; }
I would like to set a format for each of these, along the lines of
Start_Date.ToString("M/d/yyyy hh:mm tt")
Do I have to code the get, or is there an elegant way to do this?

I'm having difficulties with adding sub-properties into Property sheet.
for example:
let's say I've created a web-control with a textbox in it. I can add to my web-control a new property such as:
public TextBox MyTextBox
{
get
{
return m_TextBox;
}
set
{
m_TextBox = value;
}
}
and this will be enough for me to add the TextBox into the property sheet of the web control each time i use this web-control.
My problem is with adding the TextBox properties into the property sheet with the sign "+" next to the "MyTextBox" property.
I'm using VS2008 if it's make the difference.
I'm looking for a good way to add arbitrary properties to the objects in a strongly typed list, based on the principle that I shouldn't pass a DataTable from my business layer to my presentation layer.For example, I might have a Category class with the properties CategoryId and Title. On one page I would like to fetch a list of all categories (ie. List<Category>) together with the most expensive product in each category.A while ago, I would have just returned a DataTable with some additional columns in it with the product data in, but I'm trying not to do that -- it would be trivial to set up it's not good practice. One option is to add a MostExpensiveProduct property to my Category class, but I might want to display the most recently added product in another case, or the cheapest product, so I'd end up adding a lot of properties to cover all the options. This just doesn't feel right to me.Am I missing a trick here? What is the best way of doing this? Or should I just be returning a DataTable to which I can add as many columns as I need and not worry about it?
View 3 RepliesI have a c# v3.5 framework site that I am doing some maintenance on. I wish to use Automatic Properties but whenever I try to add one, the compiler fails [as below]. I have added the System.Core.dll (and it is in the web.config ok) but still no joy.

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs.
As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup. The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using...
ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False)
... which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?
I want to know that how i use the collection class for storing some data and save it letter in the data base.
View 4 RepliesI have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:
[code]....
In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?
I have GridViews in mostly all web-pages. If data rows are too much then by scrolling down the grid, header misses.

I have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.
These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:
(in case of updating textbox.text):
[code]....
However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.
I have GridView bound to some List. In layout I created following template field:
<asp:TemplateField HeaderText="Phrase">
<ItemTemplate>
<asp:TextBox ID="phraseTextBox" runat="server" Text='<%# Bind("Phrase") %>'/>
</ItemTemplate>
</asp:TemplateField>
But after changing the content of any TextBox in column "Phrase" my List doesn't reflect that changes.
I've got a GridView on a ASP.Net page. I would like to set the DataSource of the Gridview to a trackable collection of Entity Framework objects. I though the code should look like this:
this.gvMyGridView.DataSource = entity.MyDetailedItems;
this.gvMyGridView.DataBind();
But this doesn't display any data.
I am using self tracking entities and the MyDetailedItems is a navigation property to rows from another table.
public void bindgrid()
{
MembershipUserCollection users= Syste.web.security.Membership.GetAllUsers();
Gridview1.datasource=users;
Gridview1.databind();
}
when I hover over the users using break point I have this userlist->non-public members->Values->[0] bill,[1] ian,[2] jeff-> comment,creation date,email,is approved, is locked out, is online, last activity date, name ...etc I want to bind name,creation date, email to my grid.

I have a new VS2010 .NET 4.0 Web project and the Properties Folder has gone wierd on me. It has lost teh "Open" under the right click. There is no way to get a Settings file created now.
I am unable to get to the Settings grid and no Settings file is created. I tried the help and it has the normal trip of select Properties, Open (right click), Settings Tab, etc. etc.
I'm trying to databind my GridView to a custom datasource where one of it's members/fields is a collection.
Custom object Entry
public List<EntryHour> Hours { get; set; }
In practical terms, one row consists of some normal text fields which is easy to handle. However, the Hours field is the nut to crack.
How do I, in the GridView markup bind my textfields in question to the Hours field (which consists of 7 items allways)?
