Templates - Populate List Items In Dropdown List From Placeholder?

Feb 24, 2010

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.

I have a dropdown list with the names of the months listed in it. These names are stored as int values but converted to string for display purpose.

Dropdown List Won't Populate Values From Database?

Oct 4, 2010

I'm stuck with a problem to populate a DropDownList control with values from the database using item field template in read only mode. since I'm new to ASP.NET. Below is the code and the error I'm getting:

'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: 'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

The code for this is :

ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand ="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId)">
<SelectParameters>

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category".

Populating A DropDown List With Multiple Items?

Apr 30, 2010

I am running into some additional difficulties with dropdown lists, and I'm hoping you can correct my thinking.

I have a table populated with items; ITEM_ID, ITEM_NAME, ITEM_COST.

Here is my code:

[Code]....

With this code I get this error: DataBinding: 'ITEM' does not contain a property with the name '2'.

If I remove the assignment of DataSource to c1, the dropdown generates this error: 'DropDownList3' has a SelectedValue which is invalid because it does not exist in the list of items.

Parameter name: value

How should I code this so that the user is presented with a list of ITEM_NAMES, and that the ITEM_ID is stored in the value field so I can use it when the selection event is fired? I know I could databind the source directly to the dropdown list, but I am trying to understand the behind the scenes working of a dropdown list object.

Forms Data Controls :: Populate Dropdown List With Special Character

Nov 1, 2010

Using a gridView to read some data from a SQL database. The user can select a record in the gridview. On the SelectedIndexChanged property I populate this to a couple of text boxes & drop down list; txtCountry,ddlProvince,ddlCity.

I have special characters in France ( accent marks) and when I populate it to the drop down list it fails giving out the error message "SelectedValue which is invalid because it does not exist in the list of items".

Example of items that I try to populate are as follows. ( separated by commas) ÎLE-DE-FRANCE , PROVENCE-ALPES-CÔTE D'AZUR , RHÔNE-ALPES, DRÔME,ISÈRE ........ When I looked in the drop down lists for Province and Cities I see those Provinces there in the item list. When I debug line by line the word ÎLE-DE-FRANCE comes out like LE-DE-FRANCE which is not there in the drop down list. Got to know the Î is typed by pressing down ALT+206 and lloks like this is what is coming in at the start of the string above.

Security :: Multiple Role Membership / How To Populate A Dropdown List With Users

Oct 13, 2010

I need to populate a dropdown list with users who match certain role criteria. For example, if I have the following roles: Manager, Employee, Supervisor I would like to populate the list with only the Manager and Employee roles. Some individuals have multiple roles and they should be excluded if they also have the Supervisor role as illustrated below:

Name: A , Role(s): Manager, Employee, Supervisor

Name: B, Role(s): Employee

Name: C, Role(s): Manager, Employee

The final list should only contain names B & C.

I can use Roles.GetUsersInRole("Employee") but I am not sure if this is efficient or not.

Jquery - Removing Items From Dropdown List (client Side)

Feb 10, 2011

So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:

a
b
c

Second one:

c
d
e


Third one:

d
e
h

and so on.

So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.
