I have a small vb.net-based page, displaying a booking form with a large dropdown of movies.
now this page can be opened on two ways, one is directly (no preselection=no problem)
the second way is with a link like "page1.aspx?movieid=400" which should open the booking table and preselect the movie with ID 400.
How can I do this in VB.Net?
I am trying to preselect an item in a drop down list box based upon a value I pass in from a data reader. When I place a "Watch" on the drop down list box, the code I am listing below says that it does what it is supposed to and sets the "selected item" to the one I want BUT when the page is rendered and comes up the first item is always selected. It is like it loses the set when the page is loaded or something.
Here is the code....
<td style="width:33%"><asp:Label CssClass="formlabel" ID="lblRU" runat="server" Text="Reporting Unit: "> </asp:Label> <asp:DropDownList ID="ddlRepUnitTeam" runat="server" DataSourceID="SqlDataSource1" DataValueField="MR_LU_TEAMS_PK" DataTextField="MR_LU_TEAMS_NAME"> </asp:DropDownList> </td> <%
For Each item As ListItem In ddlRepUnitTeam.Items
If item.Text = myReader.GetString(0) Then ' ddlRepUnitTeam.Visible = False
item.Selected = True Exit For End If Next %>
For giggles, I add the ".Visible = False" in there as a test and commented it out later. That doesnt work either. The item still is visible. I know the IF statement passes as it enters into the if statement using debug mode and hits the "Exit For" so I know the condition is being met. I am at a loss over this one.
Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:

I have drop down list in my page that contain cities name i bind it from city table
city id
Paris 1

I had a bunch of controls (radiolistboxes, checklistboxes, dropdownlists) and each one had a pre-render to preselect a value from the database, but since most of them got the value from different fields from the same record in a database, I decided to put everything together in the page pre-render and make it more efficient. Problem is, it seems the controls don't have their items yet in the page pre-render, while they do have them in the respective control prerender. I thought page and control prerenders didn't have any difference except that page prerender fires before the controls prerenders, but is there some databinding happening somewhere that I am missing?

THE SELECTED DROPDOWNLIST DATA IS REQUIRDE TO BE DISPLYED IN A GRIDVIEW.
I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
I need to add an item in a dropdownlist and also modify the value of that item, but im getting an error : "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"here's my Page load
Dim rt as new OleDbCommand("Select * from Question ", con)
dim rd as OleDbDataReader
rd = rt.ExecuteReader
Dim a as new OleDbCommand("Select Count (*) as C from Question" , con)

I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>

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 have a stored procedure which is returning me several rows. I am presenting the rows as item in a repeater. I need to move one of the rows down to the footer template, based on a condition. For instance, if my stored proc is returning a column called A, I need to drop this record to the footer item, if the A column value is Total. I have no idea how to do that.
View 2 RepliesMy Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.
How can I get the regular key name working?
Visual example from the immediate window:
I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
