Asp.net Mvc - DropDownListFor Does Not Set Selected Value
Sep 9, 2010
I have a view that is displaying a Drop down list using the HTML helper DropDownListFor
[Code]...
I'm having an issue with the view setting the selected value on the drop down list if we are reloading the Search View. I've checked the View Model (ItemSearchViewModel) when it comes into the Search function and the Manufacturer is populated with the proper selected value and successfully passes that value back to the Search View. At some point the data passed to the view doesn't seem to populate the selected value, was wondering if anyone had some ideas on why this is happening and what I can do to fix it.

I am using Html.DropDownListFor to build a select list. It is a simple list of numbers from 1 to 100. One of the parameters - selectList As System. Collections.Generic.IEnumerable(Of SelectListItem) - is the list's options, which I have usually built manually, like this: [code] But this time I want a list from 1 to 100. And I refuse to manually create it :)Is there some sweet LINQ magic to build a list for me?

In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

I've mainly been doing ASP programming up 'til now, and I have a pretty simple question.
I'm creating a program that will copy a selected file to a selected directory, and I want to store recent files/dirs so that they can be selected from a combo box. I was planning to just create a settings with "files" and "dirs", and just store the strings as | separated values (since that's an illegal file character).

I'm trying to get this to work so I can return only a list of items, instead of a list of items and the selected value. Is there a way to make the DropDownList select the selected ListItem from the ListItemCollection (or any other type of collection)?

I am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.

I want to have my current row stand out as the current row by virtue of the background color.I also want my current cell stand out from the row color.
in other words i want to controll the background of the current cell as well as the current row, and have these colors different from each other as wel as the background from the non current cells.
I am getting confused with the notion of the current row vs the selected row.I have tried messing with the default row style.selectedbackgroungcolor as well as the same for the default cell style, but cant get it to work the way i want.
i can almost get it if i set the selection mode to full row, but then cannot get the current cell to have a different background color.

If I try to get a value from a static DropDownList, <asp:listitem> works.

i am building an application which sum column of datagridview based on the row you are in .
when i try to get the current row using RowEnter event ... i found out that this event occurs when a row receives input focus but before it becomes the current row....
when i try to get the current row using SelectionChanged event it returns current row but it also slows down my app because this event activates when you move from one cell to another ...
so what i need is an event or some code that gets me the current row after the selection has changed but to work only when user changes a row

I have an IfThen Statement that states if a row is selected, then execute, else, display message. The code runs fine if I select a row, however when I try and proceed without selecting a row I get an error instead of the message I want to display.
Here is an example of what I'm trying to do:
Protected Sub btnReplace(ByVal sender As Object, ByVal e As EventArgs)
Dim row As GridViewRow = device_list.SelectedRow
If (row.RowState Or DataControlRowState.Selected) > 0 Then
Message.Text = "You selected " & row.Cells(1).Text & "."
Else
Message.Text = "Please select a device."
End If
End Sub

I have a problem keeping a selected value in a combox. I select a row in a datagrid and load another form, based on this selection the form and combobox is prefilled with data. When I close this form it sets the selected value on the combobox back to 0 and gives me an error 'There is no row at position 0', how can I maintain the initial selected value to work around this error
