Forms Data Controls :: On Dynamic Control The DropDownList SelectedIndexChanged Event Fires Several Times?

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 :

[Code]....

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

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...

Forms Data Controls :: Fire SelectedIndexChanged Event Of DropDownList When SelectedValue Is Coming From Database Table?

Jun 28, 2010

I have a form which has some dropdownlists (ListItems "Yes" "No"). I use my form to Enter data & submit to database and use same form to Edit aswell. Like I redirect to this form from another page with a QueryString. If there is a QueryString then SELECT * FROM Table WHERE ID = QueryString's value & fill all the controls in the form like

[URL]

I have certain things to do when DropDownList.SelectedValue = "Yes" so I can use SelectedIndexChanged event handler & AutoPostBack="true" when submitting form for the first time. Now when I edit the information(Data filled from table as stated above). How can i automatically fire all events like DropDownlist SelectedIndexChanged in the page_Load iteslef so that all the things that are supposed to be done when DropDownList.SelectedValue = "Yes". I'm posting my test code for reference to explain what I'm trying to do. This is just the Idea. I have something else to deal with if i can get this stright. I need to dynamically add controls based on the values of DropDownList. please suggest some thing guys.

Forms Data Controls :: Update Databse With DropDownList In GridView, SelectedIndexChanged?

Nov 20, 2010

I am new to asp.net (I may use some incorrect termology while I explain my issue...) and need some help with DropDownList in Gridview. Currently I have a GridView set up with three Columns bound to a database: Column1 - some kinda of index, Column2 - string, Column3 - DropDownList(called Active). So far when I build the page, all the columns show up and the DropDownList appears and the values are bound correctly. I want to change a value in the DropDownList and automatically update that value in my database.

I have set AutoPostBack = true and I made a DataObject (called UpdateActive) to update the database (it takes 2 inputs, the Column1 index and Column3 DropDownList value).However, I don't know how to find the row that I am changing, is there a way to figure out what row it is (like finding the Column 1 index?). Also, I don't want to have to click a button to update the data.

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....
