I have a List in which I select users from db each time a sql query runs with certain value and selects one user in the time thus I cannot limit identical users in sql.
I have list with:
list[0] = "jerry"
list[1] = "tom"
list[2] = "jerry"
I want any (first or last doesn't matter in my case) to be removed from the list.
Im Using asp .net with Vb Coding.
I have to remove the list of selected items from listbox .
Dim i As Integer
For i = 0 To listbox1.Items.Count - 1
listbox1.Items.Remove(listbox1.SelectedValue.ToString())
Next
My doubt is If i run the page again the listbox shows the items which i deleted already.
For my site, I have a list of users and a list of events. I will be assigning users to each event. I have a table named EventUsers to hold this data:
EventUsers
EventID | UserID
1 | 123
1 | 456
2 | 789
On my page, I want to be able to add and remove users for a certain event. I could have a dropdown populated with users and an "Add" button next to it, then when I want to add a user, I pick one and click "Add". There would be a grid below it displaying all the users for the event, with "Delete" buttons for each one. The downside to this is that a database call is made for every Add and Delete.
Another option is to have two listboxes on the page - one on the left containing all users in the database, and another on the right which will contain users for the given event, and I can just add or remove from the list on the right. Then when I'm done, I click save, and it makes one database call. The only issue is that if I'm removing and adding, I'll have to delete every record in my EventUsers table for that event, and then add the changes. I've run into this before, and I've always gone with the dropdown method. What's the preferred method here?
I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

Is it possible to set tab index value for list items of ASP.Net RadioButtonList control.
View 1 RepliesI'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
I am getting this error yet I know it to be untrue.This is the code:
ddlPartnerOrganisation.DataSource = agency.AgencyGetListOfEYDN();
string temp = ddlPartnerOrganisation.SelectedValue.ToString();
ddlPartnerOrganisation.DataValueField = "AgencyID"
;
ddlPartnerOrganisation.DataTextField = "AgencyName"
;
ddlPartnerOrganisation.DataBind();
txtquantity.text = lborderlist.Items.Count.ToString(); -> this codes adds how many you have input in the listbox, now i need to know the opposite..
how to remove items from a listbox but it should also counts the how many you have left in the listbox..
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
Is there a way to easily tell which items in my css file are not used on any of my pages? I am trying to avoid going through each page individually.

View 4 RepliesI have a simple web app which contains a page of thumnail images. The user selects one or more of these images, which then appear in a 'lightbox' area on the page (just a div into which the images are cloned, to give a preview of which ones the user has chosen), and clicks a button which zips up the selected images and prompts the user to open or save the zip. I'm wondering what the best way of doing this is, bearing in mind my .NET skills are very limited? I have the jquery working which clones the items into a lightbox div. I also have the ASP.NET side of things generating a zip file and sending it to the user to download - although the zip is just hard-coded as an empty file at the moment. Currently I'm thinking that each click of the thumbnail will call an aspx page via ajax and will add that item (probably the file name of the image) to an array in a session. Then when the download button is clicked, the application will loop through all the session items, zip the files and send to the browser as a downloadable zip.
Is this a good way to do it? If so, could anyone point me towards the best way to save the selected items into an array in a session? I've really no idea how to store a list of items in an array. It would be good also to be able to use ajax to remove items from the session array too.
I would like to know, how to make sure, item with same name do not appeares 2x in the dropdownlist item?
View 1 RepliesI need functionality that will allow to discard objects from session if they are not used in specified amount of time. It is simmilar to Cache timeout functionality.
Is there any session provider (possibly free) or pattern that achieves that?

We have two websites which only difference is in the design (different images, styles, layouts..etc) but the web structure of files and cs code is the same so we want to simplify its maintenance...
The actual structure would be:
DefaultA.aspx
DefaultA.aspx.cs
DefaultB.aspx
DefaultB.aspx.cs
LoginA.aspx
LoginA.aspx.cs
LoginB.aspx
LoginB.aspx.cs
One idea would be changing the design differences at runtime depending of the origin website, but we dont like much this because performance, abstraction in designing them and url confusion...
Another one is sharing the cs (both aspx inheriting and using the same cs) file but we never have done or seen it done in any website before so we wonder if its a good approach...
I have a db table MemberOccasion with two columns: memberID and occasionID where I keep members votes for occasions. A member can vote for several occasions. Every time a vote is inserted I need to check how many members have voted (and compare against the number of registered member in another table, but I do the comparison outside of this query). My question is this: Is it possible to do adjust the query below to accomplish this?
This is how I count all memberID in MemberOccasion:
[Code]....
with the result that the data in the table below would be counted as 8. Instead I need to count each memberID once. The result I want is that five members have voted.
memberID occasionID
1 28
1 30
2 30
3 29
4 30
5 28
5 29

I know the employee's ID and would like to remove it from my List<Employee> listOfEmployees.
The listOfEmployees.Remove seems to require index of the item to be removed.
I want to remove duplicates from this list:
List<Dictionary<string, object>> val = new List<Dictionary<string, object>>();
It does not work if I apply Distinct() in this way:
List<Dictionary<string, object>> result = val.Distinct().ToList<Dictionary<string, object>>()
Update: Problem is now solved. I used the MySQL union command to read table from the database.
I have a class name Holder. I create a List of Holder, then add Holder to it.
