Populating A Dropdown List Based On Value Selected In Previous List (mvc3)


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.

Populating Dropdown List With Previous Dates?
I have to populate1st drop down list with today's date and 100 datesprior to today. I am trying to use adddays method but in reverse order. With adddays I have today's date and next 100 dates. This code doesn't work:

Dim i
As
Integer
For i = 1
To 100
DropDownList1.Items.Add(date.today.AddDays(i-1))
Next i

The 2nd dropdown should read date selected from 1st dropdown and then populate 2nd dropdown list with 7 days preceeding the selected date.

Web Forms :: Populating Text Boxes Based On Dropdown List Selection From Stored Procedure?
I have a drop down list being populated from a stored procedure. The drop down list contains job titles and there are text boxes that I need to populate with the corresponding pay structures based on the selection from the drop down list. Those pay structure values are also located in my database. Something tells me that I will need a second stored procedure to accomplish this.

Web Forms :: Clicking The Label Of A Dropdown List - Resets The Selected Value To The First Item In The List?
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>.......

Populating A DropDown List With Multiple Items?
I am running into some additional difficulties with dropdown lists, and I'm hoping you can correct my thinking.

I have a table populated with items; ITEM_ID, ITEM_NAME, ITEM_COST.

Here is my code:

[Code]....

With this code I get this error: DataBinding: 'ITEM' does not contain a property with the name '2'.

If I remove the assignment of DataSource to c1, the dropdown generates this error: 'DropDownList3' has a SelectedValue which is invalid because it does not exist in the list of items.

Parameter name: value

How should I code this so that the user is presented with a list of ITEM_NAMES, and that the ITEM_ID is stored in the value field so I can use it when the selection event is fired? I know I could databind the source directly to the dropdown list, but I am trying to understand the behind the scenes working of a dropdown list object.

C# - Populating Dropdown List With Enum Using Reflection?
I am populating a page with controls reading properties of a class using reflection. If the property type is 'String' I will add a text-box. If the property type is enum I am adding a dropdownlist. Now I have to populate the dropdown options with enums. How can this be done?

Both the enum definition class(Assignment) and the class(classOne) using which I am populating the page with controls are in the same Namespace(MySolution.Data). While looping through classOne properties when the property name is 'SkillLevel' I will have to go to assignment class get the members of enum SkillLevelEnum and populate the dropdown.

Same needs to be done for other dropdowns also.

My Code:

namespace MySolution.Data
{
public class classOne : MyAdapter
{
private string _Model;

MVC :: DropDown List Selected Property Not Set?
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.

Selected Value From A Dropdown List Not Displayed?
i have a dropdown list which has three options. The "select" option is displayed by default.

None of the other options work when clicked.

this is the code that i use in vb:

If DropDownListSelect.Text =
"--Select--"
Then
LabelError.Text = "Select an option to continue."
ElseIf DropDownListSelect.SelectedItem.Value.Trim =
"Associate Inventory to PAC"
Then
GridViewConfigure.DataSource = tblAdinvtopac.GetData()
GridViewConfigure.DataBind()
'ElseIf DropDownListSelect.SelectedItem.Value.Trim = "Bench to Bench" Then
'ElseIf DropDownListSelect.SelectedItem.Selected = "Associate Bench to PAC" Then
' MsgBox("1")
End
If

The page displays the select option by default. even when some other option is selected in the DropDown list , there is no change in the page.

The grid that i am trying to display in one of the selected options of the dropdown list is displayed otherwise.

i cant understand why the grid never shows up when i select the corresponding option in the dropdown list.

Web Forms :: Preselect Item In Dropdown List Box Based On Value
I am trying topreselect an item in a drop down list box based upon a value I pass in from a data reader. When Iplace a "Watch" on the drop down list box, the code I am listing belowsays that it does what it is supposed to and sets the "selected item" to the one I want BUT when the page is rendered and comes up the first item is always selected.It is like it loses the set when the page is loaded or something.

Here is the code....
<td style="width:33%"><asp:Label CssClass="formlabel" ID="lblRU" runat="server" Text="Reporting Unit: "> </asp:Label> <asp:DropDownList ID="ddlRepUnitTeam" runat="server"DataSourceID="SqlDataSource1" DataValueField="MR_LU_TEAMS_PK" DataTextField="MR_LU_TEAMS_NAME"> </asp:DropDownList> </td> <%
For Each item As ListItem In ddlRepUnitTeam.Items
If item.Text = myReader.GetString(0) Then ' ddlRepUnitTeam.Visible = False
item.Selected = True Exit For End If Next %>

For giggles, I add the ".Visible = False" in there as a test and commented it out later. That doesnt work either. The item still is visible. I know the IF statement passes as it enters into the if statement using debug mode and hits the "Exit For" so I know the condition is being met. I am at a loss over this one.

DA_Class DAobject = new DA_Class();
ddl.DataSource = DAobject.GetItems();
ddl.DataTextField = "Description";

C# - Cant Set Dropdown List Selected Value In Page Load
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?
