Web Forms :: DropDownList Conditional Binding / How To Add The ListItem To The Control In The Code Behind
Mar 4, 2010I have the following Dropdown List
[code]....
My problem is that some of the users that used to be in the list have left the company so we want to mark them inactive. When they are inactive they should not show up in the DDL to be selected to be assigned to. But there are existing records that they are already assigned to. If they are no longer able to be assigned their is a column called IsActive in the db that is set to 0. The Datasource filters for only == 1 when filling the datasource.
When it tries to render the control where a selected value is not in the list the Browser throws an error. I can not seem to find an event where I can intercept and set a value that is legal.
The solution I would like would be to add the listItem to the Control in the code behind then call the bind("AssignedTo") in the code behind instead of in the aspx page. This way linq would still handing the update of the DB record for the update event.

Forms Data Controls :: Select 1st Row In Gridview When Page Index Changed
Jan 14, 2010I have a gridview with paging. I have a style set for a selected row (highlights the row in light orange). What i would like to do is that each time a user chamges the page, the selectedIndex & selectedRow automatically becomes the 1st row of the selected page. So i would like to see the orange highlight on the 1st row of the page to indicate that the row has been selected.
I have tried GridView1.SelectedIndex=0 but this only seems to select the index of the 1st record in the whole datagrid. Does anyone know of how to set the 1st row of the page to the selected row each time the pageindex is changed?
Forms Data Controls :: Way To Select Item In A ListView - How To Get Appropriate Index Number
Sep 7, 2010I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

Custom Server Controls :: Declaratively Adding ListItem(s) To DropDownList In A UserControl?
May 13, 2010[VS 2010 RC1, .NET 4.0, VB.NET]
I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).
Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...
[Code]....
My code-behind looks as follows:
[Code]....
I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.
I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.

View 1 RepliesForms Data Controls :: Setting The Selected Index / Value In A DropDownList?
Feb 8, 2011I 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.
