DropDownList SelectedIndexChanged event not fired when programatically setting SelectedValue

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :ASP.Net

In our asp.net web application we load the dropdown list boxes in the page load.  We than set the SelectedValue of each dropdown list box to an object from session.  We have event handlers for many of the SelectedIndexChanged events of the drop down lists boxes, but these do not get executed when we set the selected value programmatically.


Someone else mentioned this is by design, and only when a user manually changes the drop down list selected index, will the event get raised.


I would think this is a common scenario of wanting the selectedindexchanged event handled when setting the selectedvalue/selectedindex/listitem's selected property, of a DropDownList.  What is the suggested way to handle this?  Is there a significant drawback of creating a custom control inherited from DropDownList that has the functionality of raising this event when changing the SelectedIndex or SelectedValue?

Questions about setting dropdownlist selection programatically

I don't understand some things about setting the current selection of dropdownlists from code. I have a dropdown list of people's names where the Value is a Person_ID.  This gets loaded from SQL, and I added an Item which is "Please select..." to the top of the list and gave it a value of 0.  AppendDataBoundItems is true.   If I want to select an item from code can I use dropdownlist.SelectedValue=8 (for example)? Do I also have to set the SelectedItem.Text or does tha above do that for me? Can I instead set the SelectedIndex to some number if I happen to know it?  Will that set the SelectedValue and SelecteItem for me? If I want to set the list back so that nothing is selected (and Please select... shows) should I set SelectedIndex=0?  Is that the same as setting SelectedValue=0 in this case (since "Please select" has a value of 0)? I guess I'm confused on which of these 3 properties I should be using, to select an item (or deselect all items) in the list, using code. Thanks.

Strange connection between ViewState and DropDownList's SelectedIndexChanged event


So, I have this code (just for example):

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <form id="form1" runat="server">
        <asp:Label ID="Label1" runat="server" Text="Sort by:"></asp:Label>
        <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" 
            <asp:ListItem Value="A" Text="A"></asp:ListItem>
            <asp:ListItem Value="B" Text="B"></asp:ListItem>
            <asp:ListItem Value="C" Text="C"></asp:ListItem>
            <asp:ListItem Value="D" Text="D"></asp:ListItem>
        <asp:GridView ID="GridView1" runat="server" onsorting="GridView1_Sorting">

The Code-behind file looks like that:

Creating a custom drop down field type with SelectedIndexChanged Event

Hi All, I am trying to create a custom drop down field type and I was able to acheive that using the MS link http://msdn.microsoft.com/en-us/library/bb861799.aspx. As per the link, once the custom field is created we can override the "Validate" method to write the Validation logic and that works fine for me too. However I am facing a challenge even before going to Validate . Let me explain my actual requirements here. I need to build a custom drop down field and expose the field to the user in "Edit Properties " Page of a document library. Along with this field, I will be having some OOB site columns in the Edit Properties Page (Ex: Title, Subject etc)  . When user selects a value in the drop down, I need to hide/show few OOB site columns based on certain criteria.  I am facing a challenge of how to capture the "SelectedIndexChanged " event for the Custom drop down field in Sharepoint (Can we wire the SelectedIndexChanged event to a custom dropdown field type) ? Is this acheivable in SP 2010 Custom field type ? If so, how can I do it ? Can any of you kindly help me here?   Regards, Yesh

Drop Down Listbox SelectedIndexChanged Event not firing when I programmatically change selection

I have two drop down listboxes (DDL1 and DDL2).  When DDL1 has an index change, DDL2 then has a refresh of list items based off SQL Server SELECT from a table.  The database isn't the problem.  Everything works perfectly when the user selects a new item manually from DDL1.But in my code, I save the user data from the selection of DDL1 in a separate table.  And then upon rendering of the page (Page_PreRenderComplete), I do a SelectedIndex assignment of the value of what's saved in the db table.  That works just fine, it selects the DDL1 item, but DDL2 is unaffected, as if DDL1's SelectedIndexChanged event isn't called like it would be if manually changed.  How can I get around this?Thanks in advance. :)

Setting printer duplex programatically

How do you programmatcally set a printer to duplex?   The information I've found online indicates that GetPrinter/SetPrinter should do the trick, but so far I've had mixed results.    I'm automating Microsoft Word to print documents.  Some of the documents required to be duplexed.  So far in my research I've found the following web pages that provide somewhat helpful information. http://support.microsoft.com/default.aspx/kb/315720 How to enable and disable a printer by using the SetPrinter function in Visual C# http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q140/2/85.asp&NoWebContent=1 How To Modify Printer Settings by Using SetPrinter http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q167/3/45.asp&NoWebContent=1 How To Modify Printer Settings with the DocumentProperties() Function http://support.microsoft.com/kb/828638  How to set duplex printing for Microsoft Word Automation clients (This article appears to be starting pointing for the CodeProject article) http://www.codeproject.com/dotnet/NET_Printer_Library.asp  Changing printer settings using C# I've included the code I'm using now.  I don't get any errors and everything appears to work, but the Duplex setting on the printer is not set reliably.  My check is to open the printer's properties and the "Pr

ItemAdded event not getting fired

Hi, I have ItemAdded event created. I have added a function in that. The function counts the number of files in the subfoldes of the list. I have build the class file, and created it as a feature and activated the feature. I am not sure if my code is being hit. This is the code i have used. [CODE] namespace ItemCountEventHandler {     class Constants     {         public const string url = "Server Name";         public const string listname = "list name";     }     public class ItemCounting : SPItemEventReceiver     {         public override void ItemAdded(SPItemEventProperties properties)         {             //   base.ItemAdded(properties);             GetOpenItems();         }                   public static void GetOpenItems()         {             using (SPSite site = new SPSite(Constants.url))     

What event (if any) is fired on calling ShowDialog on hidden window

I initialize a window at the launch of my application and hide it, so that when the user needs to launch it I can quickly show it. I am using showDialog to show the window. I use this window at multiple places. So when the user is done using the window I again hide it. My question is how does the window know that it is visible. 'Loaded' event is no longer fired when I can ShowDialog to show the window. ('Loaded' event is fired the first time I create the window and hide it). Is there any other event that is fired on calling 'ShowDialog' on a hidden window? Thanks for your response.

Dropdownlist not firing SelectedIndexChanged on first item with autopostback true

Hi: Has anyone ever found a work around for the well documented and well known bug, the dropdownlist bug? Specifically where the SelectedIndexChange event does not fire on the first listitem, althought both autopostback and enableviewstate are true? In other words, if the first three items in the dropdownlist are red, blue, green, if you select green, the SelectedIndexChanged will fire, but if you then select red, the first item in the ddl, the event will not fire. All listitems will fire the SelectedIndexChanged event, except for the very first listitem. The HACK has always been to include a dummy item as the first list time like"Select a Color" to get around the first item bug. I have got a situation where I cannot use that hack. Ideas?  TIA, Bill  

How to Capture a DropDownList Selected Index Change Event

I have a gridview that receives data based on selection from a primary dropdownlist object. Works. Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works. Problem. How do I force the used to  change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "Please make a selection". Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.   Thank you.   Ayomide 

Dynamic DropDownList ListItemCollection - Event Handler

Hi and thanks in advance. Description: I am building drop downs dynamically then adding them to a panel, when postback occurs it does not hit my event handler. However I CAN get the event handler to be hit if I remove(comment out) the properties DataTextField and DataValueField while I am rebuilding the dropdownlist within OnInit on eachpostback. However when the dropdownlist is in this condition the sender to the eventhandler does not have it's properties like SelectedValue[Index] set. Step 1: Build and load a drop down. The following is the event handler for selectedindexchanged on the lists.  The drop down list is bound to a ListItemCollection that represent a few fields from a datatable. This dropdown is loaded into a panel and the panel in turn is loaded into a div. All of this functions as intended.protected void AnswerDDL_SelectedIndexChanged(object sender,EventArgs e) { int _nextQuestionID; DropDownList _ddlSender = new DropDownList(); _ddlSender = (DropDownList)sender; _nextQuestionID = Convert.ToInt32(_ddlSender.SelectedValue); DropDownList _newAnswerDDL = new DropDownList(); _newAnswerDDL = GetAnswerDropDown(_nextQuestionID); this.m_panel.Controls.Add(_ne

Radiobuttonlist SelectedIndexChanged When Changing dropdownlist



I have a radiobutton list that changes the contents of a dropdownlist when the selected radiobuttonlist index is changed using the SelectedIndexChanged event. Both controls are within the same updatepanel and both have autopostback set to true.

For some reason when I change the dropdownlist and cause a postback, the radiobuttonlist change event fires and repopulates the dropdownlist which effectively cancels the selection made in the dropdown.

I know something simple must be causing this behaviour but I cannot think what and my debugging efforts are not shedding any light thus far. I have tried putting a breakpoint on every procedure in my form and the first event that fires is the radiobuttonlist SelectedIndexChanged event so nothing in my server side code seems to be doing this which suggests it is something in the markup but I can't think what. 

Does anyone have any idea what may be causing this infuriating but obviously simple problem?
