View 1 RepliesI 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.
there is 3 drop down list control in in first dropdown load Districts when page load when we select or index changed in drop down1 items changed or loaded in drop down list2 according to the disrict.According to the item selected in drop downlist2 items changed or loaded in drop downlist3.
View 1 RepliesI 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

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)

View 1 RepliesI 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 user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

We are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.
