Feb 5, 2010Is it possible to change the position of the ListItem box on a CheckBoxList? I need to have something like:
[Code]....
I'm creating the ListItems dinamically with data coming from a DB and assigning one value ListItem.Name and another to the ListItem.Value. Probably each entry on the CheckBoxList will need to be something like

Web Forms :: DropDownList - Adding A ListItem In Addition To Using A SqlDataSource?
Jan 25, 2011I have a question about adding a ListItem to a DropDownList that is being bound by a SqlDataSource.
My Intention is to be able to add an item with something like "0" as a value and "--- Choose Something---" as the item.
However, the control is filled using a SqlDataSource for the DataSource.
So, the question is:
Is it possible to insert the value "0" and item "--- Choose Something---" to the control even though the control has a datasource from the database?
Web Forms :: DropDownList Conditional Binding / How To Add The ListItem To The Control In The Code Behind
Mar 4, 2010I have the following Dropdown List
[code]....
My problem is that some of the users that used to be in the list have left the company so we want to mark them inactive. When they are inactive they should not show up in the DDL to be selected to be assigned to. But there are existing records that they are already assigned to. If they are no longer able to be assigned their is a column called IsActive in the db that is set to 0. The Datasource filters for only == 1 when filling the datasource.
When it tries to render the control where a selected value is not in the list the Browser throws an error. I can not seem to find an event where I can intercept and set a value that is legal.
The solution I would like would be to add the listItem to the Control in the code behind then call the bind("AssignedTo") in the code behind instead of in the aspx page. This way linq would still handing the update of the DB record for the update event.
Web Forms :: DropDownList With ListItem To Resource - Files Breaks SelectedIndexChanged?
Jan 12, 2011I am adjusting my DropDownList on my MASTERPAGE to point to resourcefiles - like this:
<asp:DropDownList runat="server" ID="Language1" AutoPostBack="true" OnSelectedIndexChanged="Language1_SelectedIndexChanged">
<asp:ListItem value="0" Text="<%$ Resources:SiteMapLocalizations, DropDownSelect1%>"></asp:ListItem>
<asp:ListItem Value="0" Text="<%$ Resources:SiteMapLocalizations, DropDownSelect2%>"></asp:ListItem>
<asp:ListItem Value="0" Text="<%$ Resources:SiteMapLocalizations, DropDownSelect3%>"></asp:ListItem>
</asp:DropDownList>
Problem now is that my SelectedIndexChanged has broken its funktionality in MasterPage.master.vb:
Protected Sub Language1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim cookie As New HttpCookie("SelLang")
cookie.Value = Language1.SelectedValue
Response.SetCookie(cookie)
Response.Redirect(Request.UrlReferrer.AbsoluteUri)
this is for the redirecting to the referrer page
End Sub
How To Add Default Listitem To Dropdownlist
Sep 25, 2010I have a databound dropdownlist, bound to an object datasource. I want to have a default value of "None" inserted at the top of the list and I would like to do this declaritively if possible. After much googling I came up with the below code. However it does not display my default item. I was under the impression that setting the AppendDataBoundItems to True would solve this, however it hasn't.
<asp:DropDownList runat="server" ID="ddl" DataSourceID="ldsCompany" DataTextField="CompanyName" DataValueField="CompanyId" SelectedValue='<%# Bind("CompanyId") %>' AppendDataBoundItems="True">
<asp:ListItem Value="DefaultValue" Text="DefaultText"/>
</asp:DropDownList>

Custom Server Controls :: Declaratively Adding ListItem(s) To DropDownList In A UserControl?
May 13, 2010[VS 2010 RC1, .NET 4.0, VB.NET]
I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).
Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...
[Code]....
My code-behind looks as follows:
[Code]....
I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.
I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.

Validation Of Viewstate MAC Failed / Change Selection In A DDL

I read a bit abou the problem, still can't figure out why it happens, but it was written that a good workaround is :

and third : I've thought about another solution. If the problem occurred while waiting, perhaps force refresh after certain amount of minutes of user doing nothing with the page. I think that I can perform the refresh using response.redirect, but what about the "WAITING "CERTAIN AMOUNT IF MINUTES OF USER DOING NOTHING WITH THE PAGE" part?

Dec 3, 2010I have two DropDownLists; DropDownListStart displays the hours 09:00 - 19:00 and DropDownListStop displays 10:00 - 20:00. When the user chooses one of the hours in DropDownListStart I want the program to adjust what's shown in DropDownListStop so that the first hour shown is one hour after the hour chosen in DropDownListStart. How can I do that in code behind (c#)? An example: if the user choses 13:00 in DropDownListStart I want DropDownListStop to display only 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00.
