I have a databound label control (i.e. Label 3) inside an Item Template that's in a DetailsView control. I just need to get the value of those label and compare it to some string. I tried several ways (i.e. Find control, DetailsView.Row) but nothing seems to work. I don't know if I'm using the FindControl methos correctly or if I need to access the Row first and do the findcontrol method.

I am trying (unsuccessfully) to pre-select a radiobutton control (within a DetailsView control) based on a value found in a database.
There are only two values: "Yes" and "No". A field in the database has one of the values in it and I want the correct item selected when the record is displayed in Edit mode.
All my other record fields are displayed correctly--this is the only one giving me issues. I am using vb.
i've a fileupload control <asp:fileupload> called (UpImage) inside the <EditItemTemplate> called (dtlAlbums) of a <asp:DetailsView> which is inside a <asp:GridView> called (grdAlbums), when i use the below code to find the control (UpImage) i get an error at the RED line that, (Object not set to a reference of an object)
// code begins here
bool CheckFileType(string fileName)
{
string ext = Path.GetExtension(fileName);
switch (ext.ToLower())

i am saving color as a string in database
i have a gridview control
[Code]....
i need when this control bindes i want to change the color of label control ,
I have a boolean / bit value in the database called "is_paid". Depending on this value I want to Disable a button. (the same would go for example to set a textbox not Visible, but anyway)
What I want is to Disable the button, if my boolean is 1 (true).
First I tried to convert my boolean value to text:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Convert.ToBoolean(Eval("is_paid")) ? "False" : "True" %>'
/>
But got an error:
CS0030: Cannot convert type 'string' to 'bool'
However, if I use it one a Label it works fine: <asp:Label
ID="lblIsPaid"
runat="server"
Text='<%#
Convert.ToBoolean(Eval("is_paid")) ? "True" : "False" %>'></asp:Label>
So another trial I did was to CAST the data from the database to be the text that I want, like so:
SELECT not_paid = CASE WHEN is_paid = 0 THEN 'True' WHEN is_paid = 1 THEN 'False' END ....
And my code changed to:
<asp:Button
ID="btnCalculatePayment"
runat="server"
Text="Submit"
onclick="btnCalculatePayment_Click" Enabled='<%#
Bind("not_paid") %>'
/>
But got this error:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.

So I wonder, is it possible to change the "Enabled" property based on by boolean value?
I am trying to figure out a way to change the color of the text display in a label control or span inside a user control. The text needs to be displayed in a different colour based on the value returned.
<asp:Label ID="NameLabel" runat="server" Text='<%# Eval("Name").ToString()=="Flying Bats" ? "Display the text in green" : "Display the text in red" %> '/>
The text value would be one of the two. The font color needs to be ether red or green based on whats been returned.I cannot figure out how to do it.
I have been used to using non enabled textboxes (with multiline as textmode option) in the past as a way to display multiple lines in a detailsview template. However, what I want to achieve is a scenario where I can use a label with a multiline option instead of a textbox. The reason for this is that I am outputting the content in the detailsview to pdf format and I do not want all the text in a label/textbox bunched up.

I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:

I have a label inside a formview that is not bound to anything.
Lets say I have a table of customers (with a key field called CustomerID), and then another table that has all their orders (with amount spent per order (OrderID) - based on CustomerID)
On the FormView there is a key field (CustomerID) (this is to be used as an INPUT parameter to a SP - which is to return the SUM of all the customers (Order_Totals). I could nest a view within a view I suppose to get this result, however, I just want a label to simply show this ScalarValue.
Basically, I want the label to show the aggregate (SUM) total amount each customer has spent on all orders. I have a SP called SumCost with two Fields (one a grouped by field CustomerID and the other a Summed Total of each customer's orders SumCost)
SELECT [SumCost] FROM [SumCost] WHERE ([CustomerID] = @CustomerID)
I test my SP and it works great, returning the value based on CustomerID - no problem.
My problem is getting the CustomerID passed into the SP on runtime (do I put it in FormView2_Databound) and putting the value into the label (CustTotalLbl) which is inside this form.
I have a addform where I maually have placed a confirm label inside the formvieww.

This is my code down here for the outside label, which do well.

{
