i have drop down list bound in database and i want to make the first item in drop down list is <--select-->
View 1 RepliesI have a RadioButtonList with three ListItems, like this:
[Code]....
TrueRuleCondition, FalseRuleCondition, and CustomRuleCondition are protected constants in the code-behind file that I want to use as the values for my listitems. Unfortunately, the values get treated as literal values instead of having the values of the variables inserted. Does anyone know of a way to do this or why this doesn't work as I expect it to?

View 2 RepliesIn vsw2005/ASP.Net 2 i have a formview used for project management; i recently added a new set of dates and a dropdownlist for the contact name. It is essentially a duplicate of another set of dates and contact. Both dropdownlists use the same sqldatasource, but the new one is throwing an error when the form changes to edit mode:
"'ddlInstall2Engineer' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"
The error occurs even though I have a static listitem with appenddatabounditems set to true. Here is the markup for both ddl and sqldatasource (as you can see, other than id and name of field being bound to, they are identical):
<asp:DropDownList ID="ddlInstallEngineer" runat="server" AppendDataBoundItems="true"
DataSourceID="sdsInstallEngineer" DataTextField="Name" DataValueField="ID"
SelectedValue='<%# Bind("InstallEngineer_ID") %>' Width="150px">
<asp:ListItem Text="TBD" Value="0"></asp:ListItem>

I have 2 radiobuttonlist in a web forms, each contains of 4 ListItem. So there are 8 ListItems in total. It is initialised such that none of the ListItems is selected. I want to validate that at least one of the ListItems is selected when submit button is pressed. How to do it? i.e. at least 1 ListItem is selected, either from radiobuttonlist1 or radiobuttonlist2.

but when I run it, it doesnt show it, until after i chose something else and it postback then it shows it at the top. I think it has something to do with the process in which things are loading, this being first, then overriden by the sqldatasource, how can i make this load last? or maybe im just not right about this.
Why I can't change my listitem value on my dropdownlist?
View 6 RepliesMy requirement is when user clicks Add button, the textbox value must be added to listbox. The following code works well

Is 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
----------------------------------------------------------------
| label | ListItem with only Value and no Name |
----------------------------------------------------------------
How can I do this?

Remove : Cheese
I have to provide "Remove functionality" , listbox is the easiest to provide remove functionality. I cannot modify above record format. If its not possible, then what is the alternate to overcome this issue.
I 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?
I have an ASP.NET page written in C#:
[Code]....
I want to be able to hide some of the listitems, however there is no option to do this as I am only able to disable them.
I have read somewhere on the web that you can do this but the code is in VB :(
After after a solution in C#.
I 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.
I have a DropDownList on my aspx page and wanted to add ListItem programatically. The item will start from 2 years ago to 1 year later (e.g. from 2009 to 2012) so if the year change, it will be automatic. I also want the current year to be selected by default.
In the code behind, I did this:
For i As Integer = (DateTime.Now.Year - 3) To (DateTime.Now.Year + 1)
DropDownList1.Items.Add(i.ToString())
Next
DropDownList1.SelectedItem.Text = DateTime.Now.Year
As result, I'm having the items in this order: 2011 (selected), 2009, 2010, 2011, 2012. The 2011 is duplicated (I wonder why). When I view the source page on Internet Explorer, I have this:
<option selected="selected" value="2011">2011</option>
<option value="2009">2009</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>
I 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
