I've used an early binding of a dictionary<string, string> to a gridview to show Urls Text and its HRef as key-value and it works like a charm. But since I want to replace the dictionary with this one :
dictionary<string, LinkInfo>
the binding goes wrong! Should I handle some events like as onItemDataBound or something?
and the LinkInfo structure is:
public struct LinkInfo{
public string href;
public bool Enabled;
}
Is it possible to automatically bind a Dictionary to a Gridview? The closest I've got is:
Dictionary<string, myObject> MyDictionary = new Dictionary<string, myObject>();
// Populate MyDictionary here.
Grid1.DataSource = MyDictionary.Values;
Grid1.DataBind();
This binds the properties in myObject to the gridview, but I'd like to get the key as well. If it's not possible, is there an alternative, e.g. use a repeater?
My DataTable is programatically generated, and contains objects of type JobInstance in the cells.
[Code]....
When I bind this DataTable to an ASP GridView, it only displays the first column. But if I remove the "typeof(Job)" when creating the column (the line with // !!!), the GridView displays all the columns by showing the result of JobInstance.ToString() in the cells. However, I have no access to the underlying JobInstance object, only the string values that are being displayed.
I need access to the JobInstance object when displaying the GridView (for example in the OnRowDataBound), because I want to access the fields inside JobInstance for each cell to determine formatting options, and add other links in each cell.
I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object.
However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key?
I was wondering why this doesn't work:
Is it possible to declaratively bind to an Object's property.
<asp:DropDownList id="ddl" runat="server"
DataValueField="Key"
DataTextField="Value.DisplayName" />
Code Behind
var d = new Dictionary<int, MailAddress>();
d.Add(0,new MailAddress("foo@bar.com", "Mr. Foo");
d.Add(1,new MailAddress("bar@foo.com", "Mr. Bar");
ddl.DataSource = d;
ddl.DataBind(); // Error. It doesn't like "DisplayName"
I'm binding a Dictionary to a drop down list.
Say for example I have the following items in dictionary:
{"Test1", 123}, {"Test2", 321}
I'd like the drop down text to take the following format:
Test1 - Count: 123
Test2 - Count: 321
I was going along the following path with no luck:
MyDropDown.DataTextFormatString = string.Format("{0} - Count: {1}", Key, Value);
I have a dictionary with a bunch of keys and values. Keys are - descrip, department, category and item. Every key has an associated value.
Now I am trying to bind them to a check box list and I am not sure how to do this
foreach (Dictionary<string, object> dict in mods)
I have written a web project using Visual Web developer 2008 and SQL 2005. I need to create a complex query and bind it to a repeater.
I have 3 tables
Table 1 - Department
Dept_Id (int) primary key
Dept_Name (vchar)
Include_Unavailable (bit)
Table 2 - Employee
Employ_Id (int) primary key
Dept_Id (int) foreign key
Employ_Name (vchar)
Table 3 - Schedule
Sched_Id (int) primary key
Employ_Id (int) foreign key
Date (datetime)
My query is as follows:
SELECT Department.Dept_Name, Employee.Employ_Name, Schedule.Date
FROM Department, Employee, Schedule
WHERE ??
In my query I want all departments and employees listed who work on a particular date. In addition, if the Department.Include_Unavailable is 'true' I want to create a row with the department and employees who work in that department even if they are not schuled to work. I will eventually list these employees as 'unavailable' but do not want to list all unavailable employees as unavailable. Only employees that work in departments that have Department.Include_Unavailable set to 'true'
I found a example of this but it wont work for me. So I will do a clean question by asking how do I bind a dictionary to a repeater?
I work with code behind so its for the OnItemDataBound. My Dictionary look like Dictionary<string, string>();
I've got a Dictionary<string, string> object I'm creating:-

and I wanted to bind this to a dropdownlist. I know this is possible in code-behind, but is it possible to do this directly on the asp: control, something like

I have a class that maintains a static dictionary of cached lookup results from my domain controller - users' given names and e-mails.My code looks something like:

{
if (emailCache.ContainsKey(accountName))
{
return(emailCache[accountName]);
}

View 1 RepliesI have a data object where one of the properties is a collection of another data object. I never really figured out how to map this to a GridView, but I came up with a workaround. Now I am stuck and cannot figure out any way to do this in a ReportViewer.
Here is how I solved the GridView issue:
Say we have these objects:
public class BoysWithToys : List<BoyWithToy>
{
}
public class BoyWithToy
{
string FirstName { get; set; }
string LastName { get; set; }
int BoyNumber { get; set; }
List<Toy> FavoriteToys { get; set; }
}
public class Toy
{
int BoyNumber { get; set; }
string Toy { get; set; }
}
What I wanted to do was to map BoysWithToys to the GridView and present one GridView row per BoyWithToy record. Where there was more than one FavoriteToys record I wanted to list them in a bulleted list in the FavoriteToys column. I accomplished this by calling RowDataBound() for the GridView, casting the e.Row.DataItem to BoyWithToy, then looping through all of the FavoriteToys and adding each Toy to a bulleted list, then setting the column's text to that list.
I have no idea how to accomplish anything similar in ReportViewer. If I simply drag the BoysWithToys DataSource to the designer and run it, the FavoriteToys column shows '#Error'.
We know that using something like Bind("CustomerName") can be used in the Text property of a label control inside a gridview, where CustomerName is a property of the object whose collection is bound to the gridview. If that property is of a complex type (object of another class), how do we use a property of that inline object as a binding for the gridview column?

how can I specify DataKeyNames for a GridView when using a dictionary as DataSource?

In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.

,@PageSize INT = 5
,@RecordCount INT OUTPUT
[Code]....
And for my datalist2 i need these column

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.
