I have a dropdownlist that is being populated using linq. The code for linq is below
[Code]....
When the page is viewed the dropdownlist show the following;towels, shoes, etc. What I would like is the default item to be nothing. That is when the page is viewed then the drop down list should show something like this "select category". Right now it is starting by showing towels, which is quite irritating, since if I want to see towels I first have to select something else and then go back and select it!
I have a dropdown list which I bind through a datasource. How can I inject a default value to it? My db doesn't have a default value and changes are not permitted!
I have a field that is a DropDownList. When in the insert mode I want that field to be blank - It currently is displaying the first record in the table it pulls from. I was expecting to see an initial value setting in the DropDownList properties but do not. For example - suppose I have a field named locations that consist of 4 location (below). In "Insert" mode, location currently displays Dallas. I want it to be set to blank initially and the user select one. What am I mssing?
I have a dropdownlist that is not bound to a datasource, I have hard coded a few items in the list cause the list is always constant and will never grow and there are only 4 entries init. Anyway, after i load the page and make a selection from the dropdownlist and do a postback, the dropdown always returns to the default selection...which tells the users to make a selection.How do I get the dropdown to keep the selected value after the postback? I want to be able to display the selected value all through until another selection is made.
Protected Sub LoadViewer() ddl_viewer.DataSource = SQL_Viewer() ddl_viewer.DataTextField = ("view_group") ddl_viewer.DataValueField = ("view_ID") ddl_viewer.DataBind() ddl_viewer.Items.Insert(0, New ListItem("-- Choose --", "-1"))

this is my class
Dim sqlCmd As SqlCommand = New SqlCommand("Insert_News", ClsDBConn.GetDBConn) sqlCmd.CommandType = Data.CommandType.StoredProcedure Dim sqlParameter As SqlParameter sqlCmd.Parameters.Add(New SqlParameter("RETURN_VALUE", SqlDbType.Int)) sqlCmd.Parameters("RETURN_VALUE").Direction = ParameterDirection.ReturnValue

and this is my stored procedure
ALTER PROCEDURE [dbo].[Insert_News] -- Add the parameters for the stored procedure here @News_Title VARCHAR (500), @News_Viewer VARCHAR (500), @News_Message VARCHAR (300), @News_Author VARCHAR (100),
what i have a is a dropdownlist and what i have done is set the datasource to be "select top 10 * from Orders"I have only displayed the OrderID , CustomerID and the Freight i would like to display in a dropdownlist. But what is happening is that for all 10 rows the dame value in the dropdownlist is shown. The dataset that is bound to the dropdownlist initially is all that items in the database.i would like the freight for that particualar Orderid to be displayed even if it is lets say item number 5 in the dropdownlist or itemn number 2 .
The intension is to get the all text file names in the drop down present in a particular location. When a user selects any filename from the drop down, it will show the data which is in that particular text file in a GridView.
I've done both the steps and it's almost complete but i stuck on a small issue. Probably because of non-usage of ASP.NET for a long period of time. The problem is, the drop down only selects the default value not other values.Here's my code for DropDown Selected Index Change
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { DirectoryInfo di = new DirectoryInfo(@"C:myLogs");
I have gridview that has month as a column. When the user clicks a row's edit button, that row goes into edit mode. I have created a drop-down list for month in edit mode with the values 1-12. Right now, the drop-down list shows 1. I would like it to show the current value for that row. How do I do this? Here's the code for my gridview:
How do i make the default entry in a dropdownlist not selectable? Right now I have a drop down and the users are able to select the default option that says (Select one)...here is what my code look like. I hard coded my options in there cause the list is really short and won't change ever. Right now, users can select the default entry and add it whatever list they are generating on the page...and I would like to make that default visible but not selectable.
I have a column called regdate datetime default getdate() , the column is notnull.I am using linq to sql.I have created instance of that table and when i try to insert record into the table, I am getting daterange exception.(range should be 1/1/1753 to 31/12/9999).In that object I am not setting any value to regdate property as that would be taken care by sql server.If i set regdate = datetime.now.date then record is inserted successfully.I dont want to set any value from front-ent.I want sql server to do that for me like we do it using stored procedure.
I have a Dynamic Data Website that I created after watching the video tutorials on this website (I'm new to programming, but not computers).I have a SQL Table named 'Adult' that has a 'DOB' column. I would like to add an asp:label to the Default.aspx that does a LINQ to SQL query to determine if it's someones birthday today and if so display their name and age.
I have a databound dropdownlist, bound to an object datasource. I want to have a default value of "None" inserted at the top of the list and I would like to do this declaritively if possible. After much googling I came up with the below code. However it does not display my default item. I was under the impression that setting the AppendDataBoundItems to True would solve this, however it hasn't.
i want the code to disable default selection in dropdownlist in asp.net and also on selection of a particular data field the values are displayed in the txtbox below.the dropdown should be filled with system related data like eg c:drive, d ... etc dynamically at run time.
I have several pages linked together that I want to maintain drop down selections for. I've seen a number of ways to do this with session values, etc, but I want to set the default value while still having the option of selecting other values.
Effectively, users will make selections on page 1 and then on page 2 they will use those same selections, but also potentially want to change their selections. My thought was that I could load the selections into a table in SQL in page 1 and then in page 2 call that table and set the values as variables. My question, then, is how I would set the default dropdown value to be a variable as opposed to a set value.
I am using VisualStudio2010 with ASP Webforms using C#.
