I have two databound dropdown list controls...on a data entry form.
The catch is that i want the user to select only one....
I thought that a dropdownlist behaves like a combobox in winforms.....only to find that there is always a selected item...
And asp.net has no native combobox control...
I need to validate that a user makes a selection from a select list OR they enter text into a textbox. I'm trying to figure out which validator to use. Is there a way to make a CompareValidator do this? Or would I need to write a custom validator? If custom, do I write one for each of the form elements, or does the validation happen upon submit?

I suspect one validation control can't handle both.

I want when people select All, the checkboxes for Q1, Q2, Q3, and Q4 are cleared and the "All" box remain checked. How to do it ?
"Radio Buttons Are Not Mutually Exclusive When Used in a Repeater" according to KB #316495 http://support.microsoft.com/kb/316495. This bug also exists with ListViews, and I am having a hard time developing a workaround. Is there a solution or workaround available? I'm using Visual Studio 2010.
(Here is my ASPX. I want rbGroupedSession and rbFees to be mutually exclusive. Databinding and setting controls visible attribute to true/false is done in the code-behind. I'm also setting the RadioButtons "GroupName" property correctly in the code-behind, but it gets changed when rendered in the browser -- which is bug KB #316495)..

I have 5 checkbox columns in my grid .. like

I have a form in which I have two drop downs. A decision in one fires the other. The basic rule is:
Drop Down A -> select items 1,2 or 3. Drop down B loads list 1
Drop Down A -> select items 4,5 or 6. Drop down B loads list 2
This works fine on first load and save of the form. The problem is when I edit. Lets say I selected and saved item 3 in Drop Down A. On Editing: If I change Drop Down A, the select changed event fires every time I change it except when i reselect what was saved. It leaves me in a situation where I can choose 3 in Drop Down A but are left with the wrong list in Drop Down B as the event doesn't refire on that selection.
I've tried every trick I can think of but I can't seem to get around this issue. (We've tried radiobutton lists and its the same issue. Setting the value in a variable and attempting to reset the control to clear what it thinks the original value is doesn't work either.)

I'm pretty new to ASP.Net and I came across a problem using Ajax AutocompleteExtender. Currently I'm trying to update the database table through ListView. More precisely - I'm trying to update foreign key (PARTNER_ID). Basically I need the DropDown functionality out of a Autocomplete Extender because I have a very long list of partners. I managed to get key/value pairs back to Autocomplete Extender but I can't insert the value into a hidden filed that I use to update the table. This is as far as I got - the error I get from compiler is:
Compiler Error Message: CS0103: The name 'ACEValueEdit' does not exist in the current context
Here is the code:
<%@
Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="OdgovorneOsobe.aspx.cs" Inherits="Farmex_CRM.WebForm3" %>
I have a javascript object which is converted from json to java script object. i want to display its values like after each key value pair, i want to insert new line. but i dont know exactly how to do that. below is my code, how i should insert a new line. i tried but its not inserting a new line is display.
[Code]....
I am trying to use the key value pairs with the AutocompleteExtender to allow a user to select a name of a buyer from an autocomplete list and then insert the pkId of the buyer from the database into a hidden label for later use. I can get the Autocomplete part to work; however, when I fire my btn_click event to save my form information I lose the value of the pkId. Also if I try to hide the label I get javascript errors as if the control isn't even there. I have tried hiding the control by using the visible attribute as well as style="display:none;"
View 1 Repliesi generated a private key like- keytool -genkey -alias mview -keypass mviewpass -keystore /keystore
then exported it in form of certificate file as- -export -alias mview -keystore /home/d261733/keytool_keys/keystore -rfc -file testcert.cer this gives me two files sitting in c:
1) testcert.cer (which is the certificate)

View 4 RepliesI have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)

The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:

But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist
