Dropdownlist Selectedindexchanged Event Inside A Formview?

Apr 25, 2010

I have a dropdownlist inside a formview and I'm trying to do something on the selectedindexchanged event. but I'm getting the following error:

It looks like it can't find the dropdownlist because it is inside the formview. How can I find the event?- if there is such a thing.

C# - Why DropDownList.SelectedIndexChanged Event Does Not Fire

Feb 9, 2011

I have a DropDown which is bounded to an ObjectDataSource. On its data bound event, I am adding "--select--" value on the 0 index. I have a LinkButton on the page and on its client click, i am selecting different item on drop down (using JavaScript). Suppose there are 3 items like --select--, option1, option2 and option3 and now on link button's client click i selected option3, now if I select the default value "--select--", it does not fire the SelectedIndexChanged event. If I select any other value then it fires. Why does it not work for the default value?

Web Forms :: Dropdownlist Control SelectedIndexChanged Event?

Jun 22, 2010

I have one dropdownlist control which populates values to other controls. Means upon selecting item in dropdownlist, related data is populated in other controls. I have also assigned dropdownlist's autopostback to TRUE. Everything is working good as far as dropdown has more than one item.

Whenever there is only one item, selectedindexchanged event is not fired (obviously.....) and eventually the data is not populated to other controls.

How could I get rid of this scenario? I mean which event should I use to avoid this?

At this time, I have just added the first item as something like "---Select Item---" , so when end-user has to select different item and thus the selecteditemindexchanged is fired. no biggie... but just wondering if proper solution is available....

Forms Data Controls :: Populating DropDownList Inside A ListView Inside A FormView

Jan 16, 2010

I have the following (abbreviated) code:

<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>

When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

Web Forms :: DropDownList SelectedIndexChanged Event Not Fired When Programatically Setting SelectedValue?

Oct 27, 2010

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?

Aug 4, 2010

I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :

On the Page_load event of my page i bind the data & recreate the control :

[Code]....

Everything works fine, datas are bound and SelectedIndexes are restore on every postback.

The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...
