If a user select all items in a .NET 2.0 ListView, the ListView will fire a SelectedIndexChanged event for every item; rather than firing an event to indicate that the selection has changed
If the user then clicks to select just one item in the list, the ListView will fire a SelectedIndexChanged event for every item that is getting unse...
I've found many posts where people try to work around the problem of SelectedIndexChanged not working when EnableViewState='false'.
Im a little confused why control state doesnt kick in and allow it to work, but thats bonus points if anyone can explain that too.
Some of the 'hacks' are pretty 'hacky'. Like setting a value on the views...
I did follow the article TRULLY Understanding ViewState (great article btw) and populating my drop down list is working great. I've even setup a OnSelectedIndexChange event which fires almost as great.
The problem I've found is the SelectedIndexChanged event won't fire when selecting the 0th index. It does all other times however.

I'm creating a server control that basically binds two dropdown lists, one for country and one for state, and updates the state dropdown on the country's selectedindexchanged event. However, it's not posting back. Any ideas why? Bonus points for wrapping them in an UpdatePanel (having rendering issues; maybe because I don't have a Page t...
How can one programmatically fire the SelectedIndexChanged event of a ListView?
I've intended for the first item in my ListView to automatically become selected after the user completes a certain action. Code already exists within the SelectedIndexChanged event to highlight the selected item. Not only does the item fail to become hig...
I have a dropdownlist and a textbox with a button on a form. When a button is clicked it does not go to my onclick even in the code but it goes to my dropdownlist's selectedIndexchanged event. How can I fix this?

Hi,
foreach (Book b in o.list)
{
ListBox_Items.Items.Add(b.Title);
}
After I do this, the titles are now showing up in the listbox.
When I make a selection (Single Mode), ListBox_Items (Screen) is highlighting the row selected, but event SelectedIndexChanged is not triggering.
protected void ListBox_Items_SelectedIndexChanged(obje...
Code example:
private void comboBox_SelectedIndexChanged(object sender, EventArgs e)
{
if(some condition)
{
comboBox.Text = "new string"
}
}
My problem is that the comboBox text always shows the selected index's string value and not the new string. Is the a way round this?

Hi there,
What I'm looking for is a way to mimic the MS-Access style continuous form within asp.net. In one particular case, I want a control, bound to a datasource which returns a dropdownlist for each row, bound to the value within the datasource. Any change to any of the dropdownlists' would perform an update to the database insta...
My selectedindexchanged event is not firing when I select values in my dropdown lists. These dropdown lists are implemented dynamically in the following code. I have tried changing autopostback and enableviewstate settings to no avail. I am using a static panel. Does anyone see how I can cause the selectedindexchanged event to fire?

I am creating a control that loads three related dropdownlists at runtime, and all three bind their data from a database. when the first list changes value, the 2nd one should rebind based on that value, by default selecting the first item. However, as a result, the third list should ALSO rebind based on the selected first value of the 2...

Hi,

I'm developing in VB.NET with Visual Studio 2005.
I have a ComboBox (myCombo) on a form that gets populated within the Load method.
I also have handled myCombo.SelectedIndexChanged to change a label on the form.
Edit: The way I added the event handler was by double-clicking on the combo box on the designer. Skeleton code then came up...
Good morning,

I am returning the jobs found into a DataBound GridView (namely gvwJobs), and within the HeaderTemplate I have a DropDownList named ddlSortDirection which specifies the direction...
I am generating a dropdown list in codebehind and cannot get the selectedindexchanged event to fire automatically. It works fine when put directly into the ASPX page, but I need it to be in the codebehind.
This doesn't work -
var deptList = new DropDownList
{

It's a small thing but I was just wondering...

I have a master-detail form with databound controls. When user selects the record in a listbox, all the details are updated in multiple databound controls on the form.
As it happens, they kind of 'flash', or blink, when repopulated with new data and it's sort of li...
