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
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?
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'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; }
Public Class State Public Property StateId As Integer Public Property Name As Dictionary(Of Integer, String) End Class
Name(x) contains the state name in different languages. I get a collection of State from the method StateManager.GetAllStates() and I want to bind this collection to a DropDownList. The problem is that I can't find how to set the DataTextField property to let's say stateList.Name(1) which is the english name of my state.
Dim stateList As StateCollection = StateManager.GetAllStates() Me.DataSource = stateList Me.DataValueField = "StateId" Me.DataTextField = "Name(1).Value" <-- Problem here Me.DataBind()
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:
private static Dictionary<string, string> emailCache = new Dictionary<string, string>(); protected string GetUserEmail(string accountName) { if (emailCache.ContainsKey(accountName)) { return(emailCache[accountName]); } lock(/* something */) { if (emailCache.ContainsKey(accountName)) [code]...
I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist
I m using the following code to bind dropdownlist using ADO.NET
Code: Protected Sub HeadsData() Dim conn As SqlConnection Dim cmd As SqlCommand Dim reader As SqlDataReader Dim constr As String = ConfigurationManager.ConnectionStrings("ams").ConnectionString conn = New SqlConnection(constr) cmd = New SqlCommand("Select HeadId,HeadName from Heads Order By HeadName", conn) conn.Open() reader = cmd.ExecuteReader() While reader.Read cmbType.DataSource = reader cmbType.DataTextField = "HeadName" cmbType.DataValueField = "HeadId" cmbType.DataBind() End While End Sub
I have 5 records in Heads table, but when i run the project it misses the first record and shows the remaining 4 in dropdownlist. Is there anything worng with this code ?
