View 5 RepliesI 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.

I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:
[Code]....
Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).
Is there a way to click on the previous or next button to change the value of the DropDown list? Do we need to use the javascript?

I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).Here's my code:
<asp:DropDownList ID="DropDownMake" runat="server"
DataSourceID="SqlMakes" DataTextField="Make" DataValueField="Make"
AppendDataBoundItems="True" EnableViewState="False" AutoPostBack="True">
<asp:ListItem Selected="True" Value="All">All</asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="DropDownModel" runat="server"
AppendDataBoundItems="True" AutoPostBack="True" DataSourceID="SqlModels"
DataTextField="Model" DataValueField="Model" EnableViewState="False">
<asp:ListItem>All</asp:ListItem>
</asp:DropDownList>
<asp:SqlDataSource ID="SqlMakes" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Make] FROM [Parts]">
</asp:SqlDataSource>
<asp:SqlDataSource ID="SqlModels" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT DISTINCT [Model] FROM [Parts] WHERE ([Make] = @Make)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownMake" Name="Make"
PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
'And in the VB file:
Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
DropDownMake.SelectedValue = Request.QueryString("Make")
DropDownModel.SelectedValue = Request.QueryString("Model")
End Sub
If I remove the line "DropDownMake.SelectedValue = Request.QueryString("Make")" it doesnt produce duplicates anymore. What is going on?? I swear I've spent more time developing entire iphone app.
I have a dropdownlist that contains items from a database. The set of items are unlikely to ever change. At the moment, whenever a user tries to access the View with the dropdownlist, the code retrieves the data each time from the DB. I would like to change this so that the set of items are cached and load on the application start only.
Could somebody indicate the best mechanism for this scenario? I have read up on Enterprise library which is my current preference, though any alternatives (with reasons) would be welcome.
How can I copy items hardcoded from one dropdown box to another keeping the keys and values?
drpTypes.Items.Add(new ListItem("Tipos de Acções", "1"));

drpTypes.Items.Add(new ListItem("Tipos de Condutor", "3"));
drpTypesCreateEdit.Items.AddRange(drpTypes.Items);
I have a dropdownlist in a formview that looks like this:
<asp:DropDownList ID="DropDownList5" runat="server" AppendDataBoundItems="True"
DataSourceID="SqlDataSource6" DataTextField="StaffName"
DataValueField="StaffName" SelectedValue='<%# Bind("LetterName") %>'
Width="155px">
<asp:ListItem Value=""> </asp:ListItem>
</asp:DropDownList>
I am trying to add the value from a textbox which is also in the formview into the dropdownlist as a list item. I currently have this code for it:
Protected Sub Formview1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView1.PreRender
Dim dropdown As DropDownList
Dim listvalue As TextBox
dropdown = FormView1.FindControl("dropdownlist5")
listvalue = FormView1.FindControl("textbox1")
dropdown.Items.Add(New ListItem(listvalue.Text, listvalue.Text))
End Sub
This code works and adds the new item to the dropdownlist if I have no SelectedValue set for my dropdownlist. However when I set the selectedValue I get the error message:
"'DropDownList5' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"
This is the bit I dont understand because the value does now exist in the list of items as it was added in from the textbox value. Does it try to do the selectedValue before adding my list item? If so how can I add the list item first, or do I need to set the selectedValue in the code after adding the list item?

I have a cascading dropdown list on my page. The first dropdown contains a list of events. The second dropdown contains a list of attendees. When an event is selected, an AJAX call is made to get the list of attendees for that event, and populate the second dropdown.
My problem is that for the attendees dropdown, I want the user to be redirected to a URL on the SelectedIndexChanged event, with the selected value in the query string. But on the SelectedIndexChanged event, all the items in the second dropdown are reset. Here's my code:
<script type="text/javascript" language="javascript">
$(document).ready(function()
{
$('#<%= ddlEvents.ClientID %>').change(function()
{
$.ajax({
[Code]....
When the SelectedIndexChanged event is hit, ddlAttendees is empty.
Does anyone know how I can keep the items in ddlAttendees?
