Forms Data Controls :: How To Capture A DropDownList Selected Index Change Event
Sep 15, 2010
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 "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.

2) Make a row copy, not sure about the syntax here

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
//lblResults.Text += item.Text + "
";
Label1.Text = item.Text;
}
}
No use, no value coming in to label.

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

I am having a label to show success message during the successfully save.
I am having a drop down with the name "Technology".
During on selected index change event of the drop down, i am binding another drop down with the name "Resources".
When the Button is clicked, i am showing the "success message" and on click event of the drop down, i am clearing the message by using the java script.
function ClearErrorMessage() {
document.getElementById('ctl00_ContentPlaceHolder1_lblMessage').innerHTML = '';
}
But when i change the drop down, the message gets reappeared.

I have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true);
list.DataSource = (from ap in edc.Approvers
where ! ap.approverEmail.Equals("")
orderby ap.approverEmail
select new {ap.approverEmail}).Distinct();
list.DataTextField = "approverEmail";
list.DataValueField = "approverEmail";
list.DataBind();
list.Items.Add(li);
list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.

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.
