Adding Item Only Once In Dropdownlist

May 12, 2012

I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem.

I have created a dropdownlist which I choose wizard way to fill data in it. and its property like:
DataTextField=Item

Label1. text=" You haven't choosen any items yet!"
exit sub
else
Label1. text=" You have choose"
end if

But when I start debugging this:
strItem always gets "---choose---" text eventhough I choosed other items.

Asp.net Mvc - MVC.NET In VB - Select List To Html.Dropdownlist?

Jul 20, 2010

Seems most of the examples I find are c#, so in some cases I'm left scratching my head... to make a long story short, I'm simply trying to output the selectList of items to a drop-down within my view:

My ViewModel:
Imports System.Web
Imports Whitebox.UI
Namespace ViewModels

[Code]...

All I'm trying to do now is simply output my "SelectList" within a HTML.DROPDOWNLIST() in my view.When doing a step through, my list items are showing within my "Return view(viewmodel)" watch, but I'm stuck with performing the output.

Select Multiple Values In DropdownList In Asp.net With VB?

Jan 20, 2012

I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
<asp:ListItem>Value 1</asp:ListItem>
<asp:ListItem>Value 2</asp:ListItem>

[code]....

but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?

Possible To Make List Box Item Height For Item Depending On Amount Of Lines That Item Contains?

Jan 1, 2012

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I am trying to do is select a value from a dropdownlist (ddlname), hit submit (Where the problem lies) and place the results in the redirected page that carries the value in a querystring.

Change Selected Item Of DropdownList On Button Click?

Apr 10, 2012

I have to hidden buttons on my page that I can trigger using JavaScript (__dopostback...). I also have a list of object on my page and a dropdownlist giving the user the possibility to sort those objects on the page. My code checks the current value of the dropdownlist on Databind of the list and applies the chosen sort method to the list. The first button is triggered when the user has selected another sort method from the list.

The second button is triggered when the user adds a new item to the list. Sortmethod "sort2" should be set automatically in the dropdownlist if this happens. So when the second button has been clicked, I need to set the selected item of the dropdownlist dynamically so I can check the value of the selected value later in the DataBind method of the dropdownlist and know what sort method should be applied.

I don't succeed in changing the selected value dynamically. I'm using to controls: First is the objects.vb and the second is the ObjectContainer.vb. Objects.vb contains the two buttons, the dropdownlist and an instance of the objectcontainer. The objectcontainer contains the list with objects that needs to be sorted based on the value selected in the objects control.

Objects.vb:
Private sortMethod As DropdownList
Private container as ObjectContainer
Protected Overrides Sub OnInit(ByVal e As System.EventArgs)
MyBase.OnInit(e)
EnsureChildControls()
End Sub
