So here is the deal. I am making my own program for fun, and I have this road block. Basically I have a 'Parent Form' which we'll call 'frmMain' and I also have another form which we'll call 'frmSchedule' (work with me here)

I'm using Visual Studio 2005 and ASP. NET 2.0 with this program. This is written in VB.net
Right now, we've got a Gridview that is embedded and databound into another gridview. The 2nd Gridview is hidden by default and expanded by the user. Within the 2nd gridview are several DropDownLists. The problem is that these DropDownLists are not firing the OnSelectedIndexChanged functon nor AutoPostback whenever I change the selecteditem.[code]...
I would like to change the dropdown list and whenever I make some changes it should auto post back and triggers a selectedindexchanged event for drop down list. I am having problem where it does auto post back but doesnt remember what I selected, it refreshes my page and item that i selected gets lost. I would like to do this without AJAX call. But, if AJAX is the only option, I am open to it.
<asp:DropDownList ID="ddlProjectEditor" CssClass="ddlProjectEditor" Autopostback="true" runat="server" >
</asp:DropDownList>
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim F As facility = utilities.lookForFacility
'Option to add Project information in editor

In my project when someone logs in I refresh the overhead and side menus. My overhead menu is an extended menustrip component that I have made. I am able to clear the menu, reload it dynamically but I am not able to add/insert the open windows which are managed by the mdiwindowlistitem property. These are the items named "1 - form name " "2 - form name" etc.
I have been able to copy the whole dropdown list, and with some very hacky loop work I can take out everything but the items related to the forms. But when I add them back in, they are not on my list. The related forms are still open and if you click the maximize button to shrink a open child window, and then re-maximize that same window...the items magically show up in the list.
This ManageMenus sub is called during a login change. If you breakpoint on "openwindowslist" after it is returned with data, it has the proper entries and nothing extra. It just seems that the for/each add loop does not actually add the items. Or, if it does add them, I can't see them.
Tried both insert and add functions, same results both ways.
CODE:
In my xmlMenuStrip component this is the function that removes everything but what follows the seperator. It returns them in a list.
The format of the full window menu is:

i am getting the datas from database and storing in a collectionobject. The collectionobj contains the Datas 'Name' and 'ID'.

for intloop as integer in Collectionobj.Count.Rows-1
dropdown.Items.Add( Collectionobj.Items(intloop).Name)

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.

View 4 RepliesI have created a dropdownlist which I choose wizard way to fill data in it. and its property like:
DataTextField=Item
DataValueField=ItemCode
I go to properties of this dropdownlist and then I add Items property as the following:
Enabled=true
Selected=false
Text=---choose---
Value=-1
And the code behind is that:
dim strItem as string= ddlItem.selectedItems.text
if ddlItem.selectedItems.text.trim="---choose---" then
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.
I would like to set the selected item in the combo box. It is working, If the dropdownstyle is dropdownlist. But not working, If the dropdownstyle is dropdown. How to make it work when the style is dropdown?

I have a dropdownlistbox in a webform. When the page loads, it displays the initial text, that is ok. When selection is made, it works ok. But when i tried using the text property ie msgbox(cbomodel.text), what shows in the previous text. The newly selected item is never recognized. Is there a way to bind the text to the listbox after a selection is made?

View 5 RepliesI inherited a site which I am in the middle of updating which has a DropDownList and a RangeValidator assigned to it. The data is bound to the dropdown on Page_Load. The values are retrieved from the database so the value property of each item is set to the unique ID of the item in the DB.
The RangeValidator looks something like:
<asp:rangevalidator id="ddRangeValidator" runat="server" ControlToValidate="ddMenu" ErrorMessage="Please select value in range" MinimumValue="1" MaximumValue="100000" Type="Integer">*</asp:rangevalidator>
I have a method which automatically populates this value in jQuery e.g.
$("#ddMenu").val("An Option"); This works, however, when I try to post the page the range validation fails. Then even if I manually select that value, or select another valid value it still won't validate. The only way to make it validate is to select non-valid value and then re-selecting a valid one.

I have two dropdownlist, one is State and one is City. When a State is selected, the City dropdownlist becomes populated. At that point you can select a city, however if you select a city and go back and select a different state, the city dropdownlist is populated by the cities for both states. How do I get it clear the cities for the first state?
Here is the code behind

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

I have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?
If you do a search for "ie8 back button disabled" you'll see a number of blogs with people having difficulties with the Internet Explorer version 8 back button becoming disabled. This now happened to one of my ASP .Net pages. The page uses a user control, aspx page, and a master page. It uses no redirects and seems to be happening when I click the back button and then the forward button (after the forward button is clicked, it does not fire the Load event and the back button becomes disabled).
