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
I'm tyring to bind a list of Dictionary objects to ListView, but for some reason it returns me an error, ItemTeplate
[Code]....
Code Behind
[Code]....
error says
[Code]....
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);
How do I show my Dataset results in checbox list and that too displaying checked checkboxes.Ds will be multiple rows.DS will have two column Firstname that will go to Textbox and CityId that will go checkbox list as checked.The Firstname values will repeat as per number of rows that ds will generate.My Code
BindCheckboxlist();
DataSet ds = BusinessClass.GetDetailes(Convert.ToInt32(grdview.SelectedDataKey.Value));
txtFirstName.text = ds.Tables[0].Rows[0]["FirstName"];
How to use for or foreach loop for checkbox list.
I had a problem in binding the checkbox list. Here I explain I had a database with 3 columns.

I working on a dontnetnuke module, and was wondering how can I bind a selected checkboxlist item into the databse
Now I got it like this, but this if or 'one' selected item.
But the thing I want it, that every one of them has their own Value (abPermission.TabID, TabPermission.PermissionID, TabPermission.AllowAccess, TabPermission.UserID) (tabhome = 6,6,6,6) (tabsupp = 7,7,7,7)
If I select 'one' or 'multiple' they values will be inserted into the database

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))

I have dynamically popute the data in Dropdownlist(Countries) and the On selected index event of Dropdownlist there is noeed to bind /populate the Checkbox list from database depending on the selections made from the Dropdownlist.
For example If I select Gujrata then all the cities of Gujrat should be visible and bounded to the check box list.
2) Once the checkbox list is bounded with data from the database, We need to select the checkbox from the checkboxlist and pass tyhe selected text of all the selected checkboxes fro the checkbox list as comma seperated values to database and then I need to Display in the Grid.
Below is my code for Dynamically populated/Bind DropDown list and get the States:
ASPX:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="MachineCode.aspx.cs" Inherits="SampleApp.MachineCode" %>

I'm curious to know why the database won't update on the click of the Update button:
[Code]....
According to all I've read, the above code should be sufficient. Since CommandName is set to Update, it would seem that no code-behind is necessary.
i want to update a 'name' field in my database. to do this i need user to enter
their name but i need to map their name to id field in order for correct update. i was thinking of using dictionary but not sure how to do this...
I have some class that I am using as profile:

I need to store some Dictionary in aspnet_Profiles table, so I decided to use some SerializableDictionary instead of regular Dictionary.. [Code]....
The question is - how can I rewrite SerializableDictionary class to use custom serialization (not XML)?
I'm trying to execute an aspx page but get this error.

I have 10 000 000 words, I need to use
[Code]....
to search for specific word. It is very quick in finding the word, but when loading that amount of data to my dictionary it takes a while. Could you say what is the efficient way deal with such data? This is not homework or work related, but it is my personal project.
I'm trying to move to a DataList control of a dictionary list
Dictionary <string, List <string>>
where should I insert the key and the list nell'HeaderTemplate nell'itemTemplate, but I do not know how.I tried to create the ItemDataBound event:
[Code]....
but it gives me error code sula first lien and tells me that there is no reference
I'm new to c# and .net but I think what I'm trying to do is fairly simple, however I think I'm getting stuck on variable types.So I have say 6 literal webcontrol myReq1, myReq2, myReq3.... and rather than implicitly setting them line by line I just want to run through a loop and set them dynamically. So to do this I've set up a dictionary that will contain the name of each literal, I can then run through those to add the data. This all works when I set up the dictionary by hand ie
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
myReqDict.Add(0, myReq1);
myReqDict.Add(1, myReq2);[code]...
Obviously the Text inserted would be dynamic too, but you get the idea, so all that works just fine, but I'd like to do the Add part of the dictionary dynamically as well and that's where I'm running into trouble, I want to do something like:
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
for(int cnt = 0; cnt<7 ;cnt+= 1){
myReqDict.Add(cnt, "myReq"+(cnt+1));
}
However this isn't valid, I can see why the "myReq"+(cnt+1) would not be valid as it's a String rather than a literal, but how can I convert the String to the Literal? What I am confused about is why the cnt on Add also isn't accepted, it is typed as an Int so to my mind it should be accepted
I have a Dictionary and I bind it to my Grid view...
[Code]....
But its not paging at all... is it even possibe to page if you are bound to a Dictionary?
how can I specify DataKeyNames for a GridView when using a dictionary as DataSource?
[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
