Web Forms :: Prevent The Firing Of Index Changed Event In A Dropdownlist When 'NO' Is Selected?

Mar 20, 2011

I have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code

VS 2010 - Accessing Data From Dynamically Created DropdownLists

Dec 20, 2012

I have it setup so that when a user selects an item from a DropdownList, that some DropdownLists are dynamically created, based on the results from the Database that are returned after selecting the item in the first DropDownList.

Then, I have a button that takes the data and saves it to an object I've created for this, and I try to iterate through the Controls of the Placeholder that I added the DropdownList controls to.

However, the Placeholder says there are no controls in it, when I press the button, but I can obviously see them there.

Here is some code:

When a "Pilot" is selected, I get all of the Upgrade Types that that "Pilot" has access to, then I create a DropdownList for each type of Upgrade with all the actual Upgrades of that Type:

VB Code:
For Each u As UpgradeTypeList In upgrades           
Dim lbl As New Label           
Dim ddl As New DropDownList            
ddl.AutoPostBack = False            

[Code] ....

Then, when the "Add Squad Member" button is pressed, I am trying to iterate through the controls, pick out any DropdownLists and get the values from them and add them to a List Of in an object for the Pilot info:

VB Code:
Protected Sub btnAddSquadMember_Click(sender As Object, e As EventArgs) Handles btnAddSquadMember.Click   
For Each c As Control In rowUpgrades.Controls           
If TypeOf c Is DropDownList Then               
Dim DoesExist As Boolean = False                

[Code] ....

But, the controls supposedly don't exist and no values get added to the List(Of).

Forms Data Controls :: Cannot Find Control Within Repeater When Selected Index Changed Event Is Fired

Aug 27, 2010

I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.

What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.

Forms Data Controls :: After Page Index Changed, Only Rows In First Page Are Accessible?

Jan 7, 2011

I have this function:

[Code]....

I set itemsRead and startRowIndex in ViewState:

[Code]....

This is my PageIndexChanged event:

[Code]....

My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.

These tags (named "Criterias") are listed as DropDownLists through the following piece of code:

Web Forms :: ListBox Selected Index Changed In A TabControl?

Oct 25, 2010

As you can see in the picture below i've got a Page control with inital letters which cotains a listbox showing different wood articles. When i click on a Tab, the selected tab page get's a new Listbox control with the wood articels starting with the selected initial letter.

Creating the listbox:

[Code]....

[Code]....

When i click on a item inside the listbox, following code will be executed:

[Code]....

So far, it works fine for me. But when i change the selected Tabpage, the first SelectedIndexChanged in the listbox in the new shown tabpage is not recordnized. That means i have to select a new item and click on Search = the selected Item is still the item i selected before i changed the tab. Then i select the item again and click on search the index changed is recordnized. So why do i have to click two times on search to get the new selected item after a tab page changed?

Here is the full code:
