I need to bind an ASP.NET control something like so:
<asp:label ID="lblName" Text=<%# GetName()) %>
and in CodeBehind file I have this method:
protected string GetName()
{
...
}
Is this right, or how I can do something like this?
i have a sqldatasource which will return 1 field (1 row) for an ID. I need to get that result and display it on a textbox. I would do it using a stored procedure (this was already made) but i was thinking sqldatasource is easier. Is there a way to bind that result onto my textbox?
<asp:SqlDataSource ID="ds1" runat="server"
ConnectionString="<%$ ConnectionStrings:conn1%>"
ProviderName="<%$ Connectionstrings:conn1.ProviderName %>"
SelectCommand="sp_1"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:Parameter Name="accountID" Type="Int32" />
<asp:Parameter Name="activitydate" Type="DateTime" Direction="Output" />
</SelectParameters>
</asp:SqlDataSource>
I've been looking into how best to do this and wisdom would be appreciated. For read only purposes, I've been happily using LINQ and binding it to a grid. For editing purposes, I've used the LinqDataSource control, enabled the Edit/Delete operations in the process, and I have a nice editable grid bound to some or all of the table's fields.Now I have a situation where I want to edit a few fields in table A, but there are various values in linked table B that I want to display in that grid too (no editing of those). So my query looks like the below. The fields in tblDupes (cleared, notes) are what I want to edit, but I'd like to display those tblVoucher ones.
var theDupes = from d in db.tblDupes
where d.dupeGroup == Ref
select new

A similar but different question LINQDataSource - Query Multiple Tables? sent me looking at scott Guthrie's blog entry http://weblogs.asp.net/scottgu/archive/2007/09/07/linq-to-sql-part-9-using-a-custom-linq-expression-with-the-lt-asp-linqdatasource-gt-control.aspx, where he handles various events to have a LinqDataSource with a custom query across tables. This still seems aimed at explicitly designed classes though, even if the class has only a subset of the fields.
So my question is: is there an easy way to allow committing of the changes made to the anonymous collection (a changes.Submit type action), or just an easy way to 'display' fields from another table while not involving them in the updating?EDIT: Thinking more, it doesn't have to be anonymous really. I'd be happy to define a class to contain the elements in that query, since it won't change often. But, those elements would be across two tables, even though only one needs updating. Not sure if that suggests entity framework would be more suitable - I get the feeling it wouldn't - I don't want the whole 'model' always grouping the fields in this way.

i have just found that i cant create postback triggers on the fly (i had a function that runs onclick that creates buttons and postback triggers)
so i need an alternative or a method to achieve this
what happens is onclick of a button, updatepanel1 is updateded and depending on what button you click in panel1 more buttons are added, these buttons that are added also have an oncllick event that should update a wysiwyg in panel2 with content
heres my code below, if anyone has any ideas or knows of other methods to get this to work it would be great

I would like to show the title and the price of a movie in my Gridview. The title and price are properties from the class Movie and Movie is a property of the class CartItem. Here is the Code of my gridview
<asp:GridView ID="gvShoppingCart" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="Title" HeaderText="Title" />
<asp:BoundField DataField="Price" HeaderText="Price" />
</Columns>
</asp:GridView>
The DataSource of my gridview is List<CartItem>. This are the classes
public class CartItem
{
private Movie _movieInCart;
private int _Count;
public CartItem()
{ }
public CartItem(Movie movie, int count)
{
_movieInCart = movie;
_count= count;
}
public Film MovieInCart
{
get { return _movieInCart; }
set { _movieInCart = value; }
}
public int Count
{
get { return _count; }
set { _count = value; }
}
public double getSubTotal()
{
return _movieInCart.Price * _count;
}
}
public class Movie
{
private string _title;
private double _price;
public string Title
{
get { return _title; }
set { _title= value; }
}
public double Price
{
get { return _price; }
set { _price= value; }
}

Apparently the GridView shows only first level properties, but how do I show these second level properties.
I have several controls on a page that I want to bind the enabled property to a couple of properties in code behind that are set on Page_Load. Here's an example of what I'm using to bind to the properties.
Code:
<telerik:RadComboBox ID="AssignToRadComboBox"
runat="server"
[code]...
This works fine once the page is posted back for the first 4 controls on the page.Here's the 1st control that doesn't get disabled like I expect it to. The expression is the same in the Enabled property so I'm not sure why it isn't working.
Code:
<telerik:RadComboBox ID="CategoryRadComboBox"
runat="server"
Skin="Web20"
Width="225px"
Enabled='<%# IsAdmin && !IsCompleted %>' />
I've got 2 problems with this approach:
1. I need it to happen the first time the page is loaded rather than after a postback.
2. I need it to work for all of the controls on the page having the expression.
It's too late in the development process to rewrite the page so I can't use jQuery & knockoutjs for example to do this all on the client side.

Is it possible to display the result of a function instead of the value of a property in a DetailsView Field?
<asp:Label ID="m_LabelPlantCode" runat="server" Text='<%# Bind("PlantCode") %>'></asp:Label>
<asp:Label ID="m_LabelPlantCode" runat="server" Text='<%# Bind("PlantCode(true)") %>'></asp:Label>
I have build a usercontrol in asp.net, and there is a property like the following.
Everything works fine when the bound value is an integer. However, if the bound field return a null from database, it will return a invalid cast error.
change to a nullable int is not desirable because it changes the how programmer work with the control's property in code-behind.

<asp:DropDownList ID="MonthsList" DataSourceID="MonthsListDataSource" DataTextField="Value" DataValueField="Key" SelectedValue='<%# Bind("OrderDate.Month") %>' Width="100" runat="server" />
I like to bind the selected value to the nested property 'Month' of 'OrderDate' as shown above. The property OrderDate is of type DateTime. The error I'm getting while binding to a nested property is:
A call to Bind was not well formatted. Please refer to documentation for the correct parameters to Bind.

How to bind property visible?
Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn
I am trying to bind a string that contains the ClientID of one user control to the property of another control within a GridView template column. I get the error 'lblVar02' is not declared. It may be inaccessible due to its protection level. How do I do this?

OnClientChange="<%# "toggle('" & lblVar02.ClientID & "');" %>"></uc:CriteriaType>
<uc:Label ID="lblVar02" runat="server" />
I want to do something like this where item is a local variable in the .aspx page:
<p:ProgressBar runat="server" Progress="<%#item.Completed/item.Total%>" Width="100" />
the binding expression isn't detecting the local page level variables. Is there a way I can accomplish this wihtout using RenderPartial?

I have a complicated report that nests six deep and so really hits the database hard. I want to use SqlDataReaders NOT DataAdapters and DataSets because I don't want big tables in memory.
MARS can get me the data fast, all from the one connection. But all the examples show it binding to a treeview.
I want to bind it to nested GridViews (six deep!).
Any examples of MARS binding to nested gridview/list/repeater controls of any kind?

I'm modifying an existing application. I need to be able to bind the Text property of an asp:DropDownList control to one of two fields when the page is rendered. The existing code is like this:

I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.
