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?
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?
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'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;
}
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 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:-
[Code]....
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

View 2 RepliesLet'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 have a datagrid called studentAddList which is combined by 2 tables. Now I have a reportviewer called ReportViewer1. They are both placed on the same page. Now I would like to bind the datagrid studentAddList to the reportviewer ReportViewer1. The reason why I bind the datagrid to it is because I have some filtration on the data.
