I have a DataBound DropDownList that is loading fine, but i'd like to insert another item that says "--Select--" or something instead of having the first DataBound item automatically display.
Is there an easy way to do this or do I need to manually add a dummy item?
Here is my code:
MyContext fc = new MyContext ();
ddl.DataSource = fc.SomeTable;
ddl.DataBind();
I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
Can i get a multiselect dropdownlist with option to select all and select none. I need it urgently....please send the control to arup.bhattacharya@[URL].

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

I'm trying to use ADO .NET to select data from this table in excel. I'm not sure at this point if I need to modify the table to make it more easy to select data from it. Here's what the excel table looks like
I guess I don't know where to really start. I'm pretty much trying to grab the numbers in the middle(design pressure) based on Mull length in inches and opening width. so the user will input the height and width of window. then if it's going into concrete or wood.. if it;s wood then in the clip to opening row if he uses (2)A or 3(b) he will have a DEsign pressure of 170 if mull length is 42 and opening width is 70. in the same 70 column if he uses (3)a 0r 3(b) his DP will be also 170 in this case.. So I will have a user interface and ask the user for a width of window and height of window which will be the Mull Length and what substrate(wood or concrete) based on that I want to display if u use this amount of screws A or B u will get this DP.

View 4 RepliesTo demonstrate that I could even use a Class attribute on an option elem I tried adding class attributes to options of a select elem in a static page and that works fine. I noticed that not many online resouces documented this so I figured I would explicitly set the record.

New information, I found the reason nothing occured was a simple mistake in the value being passed in for compLev. However, now it runs through the code for the correct case and does nothing to the color of the item.
I have a dropdownlist on my page that when a user selects an item sets the list for another dropdownlist. My problem is that no matter what the user selects in the 1st dropdown it resets itself to the first item in the list. I have autopostback=true and nableviewstate= true. Is there another setting i'm missing or is it my code?

So I am using a formview that gets in Update mode with a bunch of values from a sqldatasource --- but I want to fill a couple dropdowns with data from the database --- but I cannot figure out how to bind the data to the dropdown box FIRST and then select the value in that dropdown box... but I keep getting an error that the Selected value is not a part of the dropdown (I assume because the sqldatasource is trying to bind BEFORE I can get the dropdown box bound).
IE -- when I load my values, lets say a 'Crop' comes back as 'Corn' ... I want to download the available crops from the database (ie. corn, beans, wheat, okra, etc.) and then set the selected value as CORN.... SO HOW do I get the dropdown filled BEFORE I try and bind the selected value?

Using .net 3.5 and c#
have a dropdownlist (ddl2) which is dependent on the selected value of another dropdownlist (ddl1).I have set the appendatabounditems to "true" for ddl2 and have added a "Please Select" and a "Select All" options. The Options show in the list when the page first loads. When ddl1 is selected the page refreshes and ddl2 is populated, however the "Please Select" and "Select All" options have disappeared.

Let's say I have DropDownList ddlRooms bound to the datasource which returns list of available rooms from table tblRooms. On the other hand I have users, and their info is stored in table tblUsers. Using FormView frmUsers can be inserted, edited and updated... frmUsers is be bound to separate datasource. To each user, I would ilke to assign a room, so the value of txtUserRoom will be populated based on the selected value from ddlRooms. How can i pass the selected value of ddlRooms to txtUserRoom while keeping txtUserRoom stil bound to user datasource? Do I need two separate fileds or can i just put value of ddlRooms into datasource user?

I have a databound dropdownlist hooked up to a table and the query has the returned items show up in order. I also have some default items that are _DataBound like so:

I've build a Modal Popup extender with a DataBound DropDownList. The only problem I've got is that the DropDownList is being filled in the Page_Load. Even when I put the binding in the Load of the Modal PopUp extender there is no data inside my Dropdownlist.What am I doing wrong here? Because everything should work when I hit the TargetControlID.
View 3 RepliesSo, I have 3 table adapters in my dataset, and trying to configure the objectDataSource will not give me the option to select the correct table adapter.
I set up a temporary website to illustrate what I am talking about, along with pics, not much, just 4 pics.
https://sites.google.com/site/configuringobjectdatasource/
The first 2 pics are irrelevant but just in case anyone thinking I don't have it set up properly. The other table adapters are working fine, which I have gridviews being populated etc.
why it will not give me the option to select aspnet_GetRecordDatesTableAdapter?

How to display the total number of records returned in a GridView in asp.net? I want to display it in a label or if possible next to the page index in GridView... And how to provide a select option in a GridView to select all records (It should select not only the record shown in one page in GridView but all records that were returned to the GridView) or one by one record that was returned? These things (for e.g., Number of selected rows) should also be displayed in the label which I mentioned before.
