MVC :: DropDown List Selected Property Not Set?
Mar 9, 2010
I have a main "index" view that has a drop down and a submit button. When a selection is made (CampaignId) and a submit button is pressed a list of items is displayed and filtered based on the selection from the drop down list.
I've added a partial view (on the right rail) of my site that lists a bunch of campaigns. when a link is pressed in that partial view a (CampaignId) is passed to my page and the same thing happends as if you would make a selection from the drop down. The issue is that the dropdown "Campaign Name" should be selected based on the selection from the partial view.

Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.
<p>
<tr> <td ><asp:Label ID="lblContactType" Font-Bold="true" Text="Contract Type: *" ForeColor= "red" runat="server" AssociatedControlID="ddlContactType"></asp:Label> </td> <td > <asp:DropDownList runat="server" ID="ddlContactType" DataSourceID="SqlDataSource2" AppendDataBoundItems="true"
DataTextField="TYPE" DataValueField="ID" SelectedValue='<%# Bind("CONTACT_TYPE_ID") %>'>
<asp:ListItem Text="Select One" Value="0" Selected="True"></asp:ListItem>.......

I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.

I'm trying to keep track of employees in my database. I have two tables, Employees and Departments. The Employees table contains a foreign key relationship with Departments through a column named DepartmentID.
Here's my entity:
[code]....
I have a page that contains a form to add an employee. I'm passing the entity to my view page, and calling <%: Html.EditorForModel() %>
The problem is that the view creates a textbox for the DepartmentID.
How can I force the view to display a dropdown for DepartmentID that contains all the Departments in my database as the dropdown's list items? Is there a way to do this by just adding a metadata attribute to the property in my entity?

I have a list of options (IEnumerable< SelectListItem >) in my model that I want to use in multiple dropdowns in my view. But each of these dropdowns could have a different selected option.
Is there an easy way to simply specfiy which should be selected if using the Html.DropDownList helper?
At this point, the only way I can see is to generate the html myself and loop through the list of options like so:

I'm trying to set the selected value of a ddl during page load ie. before databind.
This causes "selected value does not exist" errors. So I force a databind, and add a new element if it does not exist in the data source.
However it looks like when the databind is performed later in the page lifecycle that my added element(s) are removed/overwritten.
Am I setting the values in the wrong part of the life cycle?

I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.
But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.

I want to stop postback if a certain value from a ddl is selected.
I've used VB to create a page whereby if a certain value from a ddl is selected then a hidden panel becomes visible. The problem is the likely answer to a majority of my ddl's is 'No' (or a no type response), however, even though the panel visibility remains false upon selecting No a postback still occurrs, the page refreshes and moves back to the top. I suppose this is a question with 2 possible solutions (or 2 questions rather)
1: Is there anyway of setting postback to false if selected value = No? A typical example of how my code appears is below
[Code]....
(i've used the value '1' to represenet Yes)
2: Is there a way of setting the page position after postback? As you can see in my code above i've set the focus on the next control (being a Radio Button) but i mean, is there an actual way of defining where the scroll bar is set?
