How To Set The RowStyle Of A GridView Row Depending On A Property Of The Object
Jan 20, 2010
I'm currently using a GridView and I want to set the CssClass for the Row depending on a property of the object that the row is being bound to.
I tried the following but it does not work (see comments):
[code]...
Now I could simply handle the GridView's RowDataBound event and change the css class of the row there...but I'm trying to keep a clear separation between the UI and the page/business logic layers.

<asp:GridView id="searchResultsGrid" runat="server" AllowPaging="true" PageSize="20" AutoGenerateColumns="false">
<!-- The following line doesn't work because apparently "Code blocks
aren't allowed in this context --> <RowStyle CssClass="<%#IIF(DataBinder.Eval(Container.DataItem,"NeedsAttention","red","") %>
<Columns>
<!--............-->
</Columns>

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

In the original site, master page has code-behind to check a query string parameter value. Depending on this value, code-behind dynamically modify some CSS property to hide / display master page elements.
As MVC2 has no code-behind because we are supposed to perform everything in the controllers, how should I proceed in this case ?
I see this : [URL]
It partially answers my needs but the query string processing is common to all pages. How can I move this processing in a common code section ?

my controller, I'm generically deserializing Xml. The object being deserialized to could end up being any number of different types. This, of course, won't be known at compile time. I've created a number of partial views, each of which are strongly typed to a different object that is a possible outcome of the Xml deserializaton.My problem is that I'm struggling with a good way to return the right view. I could always switch on some property in the object, or use a Key/ViewName Dictionary mapping to get the right view name, but I was hoping for something a little more generic than that.Does anyone know of a way that I could implicitly say, "return the view that is typed off of the object I have."?

I'm trying to change a Label's text property and colour properties depending if an event occurs on the page behind file.
Does anyone have a similar issue?
if (((Label)FindControl("Label1")).Text != null) - //getting Object reference not set to an instance of an object.
{
Label Labelmerchantid = (Label)FindControl("Label1");
Labelmerchantid.Visible = true;
Labelmerchantid.ForeColor = System.Drawing.Color.Red;
}

I've generated an entity framework class to handle my users from a custom db table. Now I'd like to override the password property of the EF object to Encrypt the value when it is set. From what i understand of MVC this should be done in the model where the EF object lives. I am able to do this easily in the controller but that doesn't seem like the most appropriate place as it will lead to duplicate code anywhere that needs to edit this user class. Is extending the partial class generated from EF possible for generated DB column properties?

I have a scenario where and array consists of values of different types.
During runtime I need to cast the current index to its type to get its property value
for eg: I have an array events[100];
the current index events[i] could be of any type say TYPE1.The TYPE1 could have multiple properties.During runtime, while iterating, I need to get all the properties and values of TYPE1 by casting the events[i] to the specific type, which I form as xml string and pass to DB.I'm at loss what way of reflection would achieve this.
P.S: I dont know the property of current index at runtime, which is why I'm collecting all the properties and dumping in DB.

I have a gridview which displays rows and columns all linked to an sql statement... and all works as normal.
I want to include a new column, that displays an image depending on what the value of the column is. If the column has a value - it will display an image. If the column value is null no image whill be displayed.
My sql is something like:
SELECT c.call_id, title, a.call_id as b_attach
FROM calls c
LEFT JOIN attachments a ON c.call_id = a.call_id
GROUP BY c.call_id,title,description, a.call_id
What's returns from this sql is:
Call_id | title | b_attach
1235 | title goes here | 1235
1382 | another title |NULL
So if there's something in b_attach - diplay image in gridview column, else display nothing in gridview column
My Gridview:

I have a business object that looks like this:
[Code]....
What is the value of SomeId after I create an instance of my object? I was testing it with SomeId == 0 but it wasn't working. Then I tried null which gives me an error.
What is the right way to handle this? Am I to assign an initial value to my objects' properties in the object? If not, how do check if my object has any values assigned to its properties -- in particular, int values?

Im trying to change the information on each row depending on the result from the query. Im thinking that at the minute my problem is that I'm only returning the first result from the query into the result.
e.g. query returns row 1 with '1232' row 2 '1243' but result is only ever set to '1232'

In an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum?The cache is set using:
Public Shared Sub CacheSet(ByVal key As String, ByVal value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(key & "_" & userID) = value
End Sub

I am trying to get an asp:SessionParameter of a SelectParameters, to use a property of an object in session
instead of having a string in the session like Session["CustomerID"]
Something like Session["Customer"] where the property is ((Customer) Session["Customer"]).CustomerID)
My code:
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:DBConnectionString %>" xmlns:asp="#unknown"> SelectCommand="SELECT * FROM getStoreCustomers (@customerID,@week,@day)"
ProviderName="System.Data.SqlClient">
<selectparameters>
<asp:sessionparameter name="customerID" sessionfield="Customer" /> ?????? (what is the syntax to pass the property here?)
<asp:controlparameter controlid="ddWeek" defaultvalue="-1" name="week" propertyname="SelectedValue" /> <asp:controlparameter controlid="ddDay" defaultvalue="-1" name="day" propertyname="SelectedValue" /> </selectparameters>
The class I use is like any other class (but serializable)
[Serializable]
public class Customer
{
public int CustomerID
{
get;
set;
}
}

I'm trying to reference a public property from a string. How can this be done in vb.net? I have the text value of "FirstName" stored in strucParam(i).TxtPropertyName.
This is what I'm currently doing:
Dim tmpValue As String
Dim ucAppName As UserControl_appName = CType(Parent.FindControl(strucParam(i).ParentFindControl), UserControl_appName)
tmpValue = ucAppName.FirstName.Text
How can I use the value in strucParam(i).TxtPropertyName so that I can remove ".FirstName" from my code?

I would like to change color of the gridView depending on the value from table that is bounded to the grid. I actually don't show this value on the grid. I tried by using additional field with visible=false, but the cell is string empty in this way. I don't know how to solve this in some other way?
I used this code, but as I said the value is empty:
[Code]....
Is it possible to solve this by getting value directly from bounded table and not from rows cell?
