Possible To Bind Data Asynchronously Between Two Dropdownlists In A View?
Mar 23, 2010
I'd like to achieve the following effect using ASP.NET MVC and JQuery. I've got a drop down list displaying a list of Countries. I want to make it so that when I change the value of the country, a new drop down list appears below it, showing a list of companies whose country of origin is the particular selected company. The thing is that I do not want to rely too much on controller actions because I'm using it in a Template Helper which is a "headless" view. Can I bind it somehow?

I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

I have four repeaters, that are all independent to each other. They all bind via web services on page load and then display the results.
There is a noticeable delay however and I would like to know how to achieve the following if possible.
On page load I want to begin asynchronously binding the repeaters so that as soon as the first one is bound, its result display and then the next starts binding.
I looked at update panels but from what I have read they do not have a page load trigger.

I have a field in a details view shown below
<asp:BoundField DataField="DTMON_F" HeaderText="Monday Hours From: " InsertVisible="False"
ReadOnly="True" SortExpression="HOURS" Visible="false" />
<asp:TemplateField HeaderText="Monday Hours From: " SortExpression="HOURS">
<EditItemTemplate>
<uc1:TimePicker ID="tpMondayHours" runat="server"/>
</EditItemTemplate>
<InsertItemTemplate>
<%-- <uc1:TimePicker runat="server" ID="tpMondayHours" />--%>
<asp:TextBox ID="txtMondayHours" runat="server" Text='<%# Bind("DTMON_F") %>'></asp:TextBox>
</InsertItemTemplate>
<ItemTemplate>
<asp:Label ID="lblMondayHours" runat="server" Text='<%# Bind("DTMON_F") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
Before "DTMON_F" is binded to the view I want to cut the string that is returned...Where and how might I do this?

I am working on an application that has two tables (amongst others) that are related by a Guid Foreign key. The parent table for this guid key is the aspnet_users table and the child table happens to be my employees table which has amongst other columns EmployeeID, FirstName, LastName, EmployeeType, NationalID etc. ant the referenced UserId column from the parent table. I have managed to get the dropdownlists (for UserId and Employee Type) displaying in my create view but have failed to have it create an employee since the guid value from the Dropdown list for UserId cannot bind when posting the form data. I am using Entity Framework 4 , VS 2010 and .Net 4

This is probably a simple question, but I can't seem to find an answer. One of my web pages has an ASP.NET FormView and two SqlDataSource controls. I need to show data from both datasource controls in the FormView. Most of the data will come from datasource1, with 2 or 3 items coming from datasource 2. The way I am trying to do this is by adding a label to the formview, then use custom data binding to get the data from datasource2. However, I can't seem to figure out the syntax for the bind statement

I am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?

I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.
Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.
