Web Forms :: How To Set Value Of Button In Drop Down List
Sep 20, 2010
I want to make a button that changes the value in a dropdown list (dropdown populated from SQLdatasource)This sounds strange i know but i have 4 dropdowns each hidden by panels, unless the preceeding dropdown's value is changed from it's initial value. So i make a selection from my first dropdown list & a postback occurrs triggering the next panel (and as such
the dropdown list) to become visible, this occurs again until eventually my users will see 4 drop down boxes...(all required field vals etc)

n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript">
function NextClicked() {
var _ddlStatus = document.getElementById("<%=ddl.ClientID%>");
var _selectedIndex = _ddlStatus.selectedIndex;
var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) {
_btn.ValidationGroup = "G1";
}
if (_selectedIndex == 2) {
_btn.ValidationGroup = "G2";
}
}

But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.

I have a Drop Down List which I need to bind to the database. Here is the situation. I am not using a SQLDataSource. It is built on the n-tier application. The datasource of the dropdown is referring to a method in the C#class. That method has a generic array list which populates information into the arraylist. The Arraylist is the parameter that is returned to the DropDown List.
I have also set the Text property of the Drop down list
Text='<%DataBinder.Eval(Container.DataItem,"Employee_ID")%>'>
However, it is not populating the DropDown list, what should I do?

I am trying to write a web page where i have to select an item form a drop down list.
I am using linq to sql to get the data from the database.the strange thing is that i can register the data to the drop down list but when i select one of them the drop down list lets me to the first item. I set post back = true because i want to update the page every time an item get selected. I wrote a really simple code to check what was going wrong but still...no success. Below i am bringing the code i wrote.

I have combined my SQL result to display in drop down list in such manner:
" SAV 123-423-231 "
" CUR 234-234-212"
User selects which account to view. So if the user selects SAV 123-423-231, I have to pass in the bank account number. How do I do that?
By split? I tried doing this:
ddlAcc.text.split(" ")

Iam working on a web based form where I have a DDL to which I have attached a field validator which is not working. It should function in such a way that whenever the DDL is left to blank, it gives user an error. I have introduced that BLANK in the DDL using ListItem as I found that as the easisest way out.
<asp:DropDownList ID="DropDownList4" runat="server"
DataSourceID="AccessDataSource4" DataTextField="myState"
DataValueField="myState" AppendDataBoundItems="true">
<asp:ListItem Selected = "True" Text = "" Value = ""></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="reqState" runat="server"
ErrorMessage="RequiredFieldValidator" Text="Required Field"
InitialValue="None" ControlToValidate="DropDownList4" Display="Dynamic">

How can I make the first item in a drop down list non selectable. I want this first list-item to show up when the page is opened and want to populate the rest of the DDL from a backend DB. I don't want this default first item in the list to be selected (just want to show it as a default value)
I want it to look something like this.
Choose a State: (Appearing on the top of DDL, but cant be selected)
