How to get asp.net return drop down list to return value as int
I want to pass the value to a stored procedure as an integer. But the default appears to be as a string which is not what the store procedure is expecting.
Is there a good way to return the list values as ints?
I suspect I can you set the value on the change selection event, is there another way?
I have a dropdownlist and a save button on my form.All i want to do is return the value in the dropdown and show it on a textbox in the same form.I am new the mvc by the way
View 8 RepliesI have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
How to get the value from the dropdown to return to the TextBox? The following does not work. You can select the item from list though.
<body>
<form id="form1" runat="server">
<script type="text/javascript">
function pageLoad() {
//Same Width
$get('ListBox1').style.width = $get('TextBox1').clientWidth;
}
</script>
<ajax:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajax:ToolkitScriptManager>
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<ajax:DropDownExtender ID="TextBox1_DropDownExtender" DropDownControlID="ListBox1"
runat="server" DynamicServicePath="" Enabled="True" TargetControlID="TextBox1"
HighlightBackColor="WhiteSmoke">
</ajax:DropDownExtender>
</div>
<asp:ListBox ID="ListBox1" runat="server" AutoPostBack="True">
<asp:ListItem>Item 1</asp:ListItem>
<asp:ListItem>Item 2</asp:ListItem>
<asp:ListItem>Item 3</asp:ListItem>
</asp:ListBox>
</form>
Can my WebMethod return an XmlDocument as return type?
When I try to consume the web service I'm still not getting XML. It appears as though a reference to the method is being returned rather than say a string containing XML.
<WebMethod()> _
Public Function CustomerSearch(ByVal lastName As String, ByVal firstName As String, ByVal companyName As String, ByVal city As String, ByVal state As String, ByVal email As String) As XmlDocument
' Create XML doc
Dim doc As XmlDocument = New XmlDocument()
' some more code
Return doc
End Function

View 1 RepliesHow can I assign a value to the methods return var BEFORE I return the final value?
Example:

In the web servce I say
public List<Customer> GetCustomers()
{
PR1Entities dc = new PR1Entities();
var q = (from x in dc.Customers
select x).ToList();
return q;
}
(customer is a entity object)
Then I generate the proxy when I add the service.. and in the reference.cd it say
public wcf1.ServiceReference1.Customer[] GetCustomers() {
return base.Channel.GetCustomers();
}
WHY IS IT AN ARRAY? I asked for a List.
I want to return List<ClassName> & count(int) from code-behind(C#) to javascript. How can i do this?
View 2 RepliesASP.NET 3.5 C# I am joining two tables using Linq. Table names are MapAssets and ExitPoint. In Database they are related with 'has a relationship'
I am writing a function in my BLL to return the joined table
public List<ExitPoints> GetExitPointDetailsByProjectID(int iProjectID)
{
ctx = new CoreDBDataContext();
var exitPointDetails = from ma in ctx.MapAssets
join ep in ctx.ExitPoints
on ma.MapAssetID equals ep.MapAssetID
where ma.ProjectID == iProjectID
select new
{
//would like to have data from both tables here
ctx.MapAssets,
ctx.ExitPoints
};
return exitPointDetails.ToList();
}
This obviuosly doesn't work. And I dont know what to return at all. All constraint I have for the return is to be able to be bound to a gridview. is this the correct way? Or else whats the correct way?
how would i go about returning a generic list in json format, can anyone point me to any good examples.
View 2 RepliesI have a Google spreadsheet that I am reading data from and I want to load the data into a list object so I can use but I am having some issues.

View 2 RepliesI have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10.
I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to).

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

View 1 RepliesI have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?

Simply put, I'd like someone to be able to click a link, and get a one-time-use pdf. We have the library to create PDF files, so that's not an issue.
We could generate a link to an aspx page, have that page generate the pdf, save the pdf to the filesystem, and then Response.Redirect to the saved pdf. Then we'd somehow have to keep track of and clean up the PDF file.
Since we don't ever need to keep this data, what I'd like to do instead, if possible, is to have the aspx page generate the pdf, and serve it directly back as a response to the original request. Is this possible?
(In our case, we're using C#, and we want to serve a pdf back, but it seems like any solution would probably work for various .NET languages and returned filetypes.)
