Web Forms :: Validator Not Working For Drop Down List?
Mar 9, 2010
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">
</asp:RequiredFieldValidator>

I am trying to get the required field validator to work. I have given it an initial value of the first index value in the dropdown list. I is just not working. Will my contrrols residing on a View of a Multiview control effect anything. I am using all drop down lists?

I've got a form with 3 drop down lists. If I choose a report on the Actions DDL, which displays a sql report as a pdf, then select an item in one of the other DDL's, the SelectedIndexChanged event for the Actions DDL is fired again. I can't get the other DDL's SelectedIndexChanged event to fire.

I'm struggling with a web form where I have created one date field and couple of drop down lists. These drop down lists populate themselves from a backend MS ACCESS database file. My problem is that I am not able to make the two drop down menus dependent in a manner that when the first drop down menu is selected the second should be populated accordingly?
This is the code for the website form:

I am using Visual Studio 2008 and created a simple ASPX page with two drop downs in it. I am using the Update Panel so that when any item is seleted in drop down 1 the second drop down selected item will change accordingly.
I was hoping the update panel will not fix the page refreshing but I am not sure what is wrong since I still see the Page refresh.
see the code below I am using.

I am having a text box and a drop down where the drop down list is binded with database values as follows
mlocal_strStoredProcName = USADAO.StoredProcNames.PayFrequency_uspPayFrequencySelect;
oEmployee.Select(out mlocal_ds, mlocal_strStoredProcName);
ddlPaymentType.DataSource = mlocal_ds;[code]....
What i need is if the text box is left empty on ddlPaymentType_SelectedIndexChanged i would like to fire the validator

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. 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've read quite a few posts here on this issue, but none of the solutions seem to be working for me.
I have a list box and a custom validator that is using a client side function to validate.
There is also a required field validator on the page.
Here's the markup:
[Code]....
So in any case, i should have an error message on the page and it should not post back, correct?

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 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)
