I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

I have one table which contains branch codes(primary key), Branch name and bank name columns. I have 3 dropdownlist boxes. the first dropdownlist is for the branch codes. When i select the a branch code i need the second dropdownlist box to populate with the appropriate branch name and the third dropdownlist box to populate the bank name at the same time.
Is it possible to have one table like mine and acheive this, if so how do i go about doing this?
I did read up on this but only came across ones with 3 tables.
I am using Visual Basic to do this.
I am getting a problem while working with the Dropdownlist in VS2008. I am trying to populate the DDL using c# codding instead of creating DataSource in GUI. The DDL is getting populated as expected, but then I've added a label that will show the current selected item; for this I've written a code in DropDownList1_SelectedIndexChanged() :
Label1.Text = DropDownList1.SelectedValue.ToString();
I hae also enable AutoPostback for the DDL.
I have placed the PopulateDDL() method inside of the Page_Load();
But whenever I select a item, it's always giving only the first item's name as the Lebel.Text.
But when I use GUI and ceate a SqlDataSource and attach that to the DDL all works fine.
What to do??
I am populating a data bound control DropDownList with file names from a local folder that resides within a ListView control.
I am able to populate as expected, in testing list is generated - all good in that regard.
However once I set to databind by adding SelectedValue='<%# Bind("ImageFile") %>'the following error occurs
ERROR:Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I'm currently building my website and have hit a brick wall. I've not begun coding anything fro this yet as I am unable to get my head around it and not sure where to start.
I've got a database table with a list of town/ county names ( columns are id, town, county).
What I'd like to do is have a template page with set places for town/ county names and then when a particular area is searched for in google/ bing etc my template page with the relevant town/ county name is shown.
I know that's a bit vague so if you have any questions, let me know. One thing I don't want to do is manually create a page for each individual town/ county!
I am making an application that deals with vehicles. I need two DropDownLists:
Makes: All Vehicle Makes
Models: Models that belong to the selected value of the Make DropDownList
How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);
I want to populate my treeview with the values from database. How can i do it.

To speed things up for the visitor of my web page, I put a personalised dropdownlist in a session variable (as below).
The idea is that if the user is logged in and the ddl session variable is Nothing then it should be set here, and the next times the dropdownlist should be set from this session variable.
The session seems to be populated ok, but the resulting dropdownlist (ddlMenu) doesn't (it just becomes blank). I suspect that it has soemething to do with the way I try to assign it. No matter what I try I run into problems, saying that one thing is a one-dimensional array and the other thing a listitemcollection, or the like. What should I write in the last line?
If Session("aid") IsNot Nothing And Session("ddl") Is Nothing Then
Dim ddlny As New DropDownList
ddlny.Items.Add(New ListItem(vstr, ""))
ddlny.Items.Add(New ListItem(kontrstr, "PageA.aspx"))
ddlny.Items.Add(New ListItem(bstr, "PageB.aspx"))
If dt IsNot Nothing Then 'dt is a datatable, populated elsewhere
For i As Integer = 0 To dt.Rows.Count - 1
ddlny.Items.Add(New ListItem(dt.Rows(i).Item("name"), dt.Rows(i).Item("did")))
Next
End If
Session("ddl") = ddlny
End If
ddlMenu.Items.Clear()
ddlMenu = Session("ddl") 'THIS IS THE LINE THAT SHOULD BE REWRITTEN.

is there an way to populate this dropdownlist dynamically from a calendar or date function so it can cater for dates up to 18 months ahead?i dont really want to populate it from database entries or hard coded list items if there is a less laborious way.
Here is a snippet of my code...
<ItemTemplate>
<asp:LinkButton
ID="lbEdit"
runat="server"
CommandName="Edit"
>Edit</asp:LinkButton>
<asp:LinkButton
ID="lbNew"
runat="server"
onclick="lbNew_Click"
CommandName="New">New</asp:LinkButton>
</ItemTemplate>

Handles gvPunches.RowEditing
Dim i
As
Integer = e.NewEditIndex()
Dim ddl
As DropDownList =
CType(gvPunches.Rows(i).FindControl("ddlDiv"), DropDownList)
the question I have is when i enter this procedure in the code behind, ddl is nothing. what am I doing wrong in populating the dropdown for the row I am editing?
I have 3 dropdownlist controls for use with capturing birth dates. One captures the month, the next the day and the next the year. Rather than having to use 3 different xml files to populate the controls I want to be able to use just 1 xml file, but I haven't been able to work things out. I thought this would work:
<dates>
<date month="1"/>
<date month="2"/>[code]....
I thought I'd be able to assign the datatextfield of month, day or year to a given control, but this isn't working. They show up in the datatextfield dropdown in properties, but when I try to view the page in a browser I get an error that tells me the field (i.e., day) does not exist. Is there a way I can accomplish this? I am developing an ASP.NET 2.0 site in VS 2005.

I have a form with a dynamically generated checklist:

<SelectParameters><asp:Parameter DefaultValue="true" Name="ShowWaitingList" Type="Boolean" /></SelectParameters>

The following code-behind is supposed to check those boxes that correspond to values stored in a database. It fails and I don't know why.

z'm trying to create a webpage for ticket purchases. When selects an option from a dropdown list and clicks a button, I want them to be taken to the next page where a textbox will be auto-populated with their choice from the dropdown list. For some reason, I can't figure out how to get them to communicate. On Form1 I can get Form2 to open onclick but for some reason, when I put code into pageload for Form2 to pull data from Form1, it won't work. For example, on Form2 I would put the following code under pageload: textbox1.text = Form1.textbox2.text
View 5 RepliesI have the following ListView (extra code removed for clarity) :
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?
On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.

On my webform, i have one grid, 2 dropdownlist and one datepicker control.
When i select items from my both dropdown and date from datepicker control, i want to populate my grid based on above mention control selections.
1. textbox (Search for staff)
2. Dropdownlist( Search for department)
3. Listbox( Populate staff name based on textbox or dropdownlist)
I am able to populate the staffs indenpendantly according to what is written in textbox or dropdownlist. Whar i wanted to do is mix the population of staffnames from textbox and dropdownlist. In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.
