Forms Data Controls :: How To Combine Some List Items Together
Jan 8, 2011
just want to have a quick question about the value of dropdownlist listitem. I have a gridview which has its datakey value linked to a dropdownlist. In the dropdownlist I have many listitems. So I decided to combine some list items together. Originally, the values of the items are 1,2,3,4,5,6,7,8. But I want to have only 5 items by combining 5,6,7,8 into one listitem called "Others." So if the listitem "Others" is selected, the gridview will show all the records that have value 5 or 6 or 7 or 8. Is it possible? How can that be done?
I hope I made myself clear. Any question, I am happy to clarify.

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 assign a colour to a drop down list item based on it's value?For example: I have a drop downlist where I've got a bunch of items that have integer
values. I would like to highlight the items with values in 1000s in grey.
Here is what the list looks like:
list_item_name list_item_value

HEADING2 1000
HEADING3 1000
item1 1
HEADING4 1000
item4 4

HEADING1 2000
HEADING2 2000
item2 2
item3 3
HEADING3 2000

I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?

using asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.
The code:
[Code]....
So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.

On my website, registered users can make a profile about themselves suchas name, Favoirite color, hobbies, etcI have a DataTable called User which hold this information.also there are other datatables for Hobbies and Colors which list all possible options.To let the user update their choices I have a FormView in Edit mode on the aspx page whichis binded to the UserTable with a GetProfileByUserId Method and objectdatasource.
Within the formview, i have added drop down lists that are binded to the hobbies and Colors tables so they can edit their previous selection.On clicking Uodate update formview calls an Update Method that adds new selections to the User databaseNow I have two questionsIs it possible to show in the dropdown list the selected value that the User has already made?If the user only changes hobbies and not colors when they click update will a null value be passed into the data table for colors that replaces their previous selection?

Working in Access, I need to create a view which takes values from two different records in another table and puts them on one row in the view. I'm having a hard time doing this since both row items come from the same field in the original table (actually in this case, using views instead of tables).
I have two queries I try to join together, but come up with the wrong results:
vwComp1:
SELECT q.CompStatus, q.EQID, c.CompsID, q.LastName, q.FirstNameFROM _EQ AS q, Comps AS cWHERE q.CompStatus=1 AND c.CompsID=q.CompID
vwComp2:
SELECT q.CompStatus, q.EQID, c.CompsID, q.LastName, q.FirstName
FROM _EQAS q, CompsAS c
WHERE q.CompStatus=2 AND c.CompsID=q.CompID
vwAssignment:
SELECT vwComp1.*, vwComp2.*
FROM vwComp1, vwComp2
This does fine in the vwComp2 part of vwAssignment, in the sense that it displays the correct name information, etc.; but for vwComp1, it just takes the name and other fields from the first row of vwComp1 and repeats it on every row of vwAssignment. This is really strange because vwComp1 and vwComp2, when displayed individually, each correctly puts the names in each row; something like this:
Bob White Rhonda Red
Bob White Freda Freschetta
Bob White Linda Lime
Bob White Jean Green
--when it should read something like this:
Bob White Rhonda Red
Fred Redd Freda Freschetta
Jim Brown Linda Lime
Rob Black Jean Green

I would like to use the IEnumerable function Intersect() to combine a few list and get the similar integers from each list. The problem I'm faced with is that I don't know how many list I will need to compare.
Here is an example:
A{1,2,3,4}
B{1,2,3}
C{1,2}
results = A.Intersect(B).Intersect(C)
This works great, but the next time around I may have a D{1,2} next time I come across the function.
I'd like to use the Intersect method, but I'm open to new ideas as well.

I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

I'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.
