Forms Data Controls :: Getting 'System.InvalidCastException' When Assigning A Label Color Via Field Value?
Jan 25, 2010
I have a very simple FormView that has several fields on it. There is a field that either returns a "1" or "0" based on conditions in the database. If the value is "1", I want to leave the label control as is (normal font, in black). However, if the value is "0" I want to change the font to bold and change the forecolor to red. Simple, right?
I am able to change the font-bold property using the code below, but if I use the code to attempt to change the font color, I get the following error message for this line:
An exception of type 'System.InvalidCastException' occurred in App_Web_hoge3m1x.dll but was not handled in user code
Additional information: Specified cast is not valid.

I want to select all the values from a table in my database and then put each value in order into labels that are on the asp page.
I can Select all the values from that database fine but I am rather stuck as how to put the values into the individual labels? Here is the code I have connecting to my database.

How can I put the DateTime value into Label1 and the Decription into Label2??
I have had a nose about but can't seem to find the information I need.

I now can reference a field in the formview, but, assigning it a value is fighting me.
I want to assign the UserName field in the formview with the login name from the Master (HttpContext.Current.User.Identity.Name).
(A) I tried the likes of: FormView1.FindControl("UserName").DefaultValue = username but of course that doesn't work.
(B) Alternatively, I tried to edit the SQL so that I passed it the HttpContext.Current.User.Identity.Name but didn't have any luck.
InsertCommand="INSERT INTO [TechUserName] ([CertName], [CertLevel], [CertLast], [CertFreq], [CertDue]) VALUES (@temp1, @CertLevel, @CertLast, @CertFreq, @CertDue)"
temp1.text=(HttpContext.Current.User.Identity.Name)

The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

System.InvalidCastException iterating through Viewdata
I need to replace the code

for dropdown in the following manner for some reason.
<% foreach (Hexsolve.Data.BusinessObjects.HSPartList item in (IEnumerable)ViewData["Parts"])
{ %>
">
<%=item.PartName %>
<%=item.IssueNo %>
<% } %>
I am getting error converting SelectedList to IEnumerable) Error: Unable to cast object of type 'System.Web.Mvc.SelectList' to type 'System.Collections.Generic.IEnumerable`1[Hexsolve.Data.BusinessObjects.HSPartList]'. Is this the right way to iterate through viewdata[].

I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

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.

Stored procedure:
[Code]....
This code returns MdaID and StateID, I want to assign them in this manner:
MdaIDLabel.Text = MdaID and StateIDLabel.Text = StateID, but I am not sure how to separate the two values and then to assign them as I have indicated above. Since my function has a "void" return -
MdaIDLabel.Text = GetMdaState({0}, 64114);
StateIDLabel.Text = GetMdaState({1}, 64114); - will not satisfy the requirement.
I am working with VS 2008 VWD, .NET 3.5 SP1, C#, SQL Server 2008 Express

I have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?

I have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?

I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
