I am using Repeater to display the data.
to get the data from database i am using
<%# DataBinder.Eval(Container.DataItem, "datafield") %>
when i build it... it build successfully but in error list i found
Name 'DataBinder' is not declared.
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?

In my project i am was getting error:
error:requiredPermission attribute not declared
to resolve this i did Google [URL] and then i found that i will have to add "xmlns" in my webconfig's configuration tag and i did that:
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
but then i got new error:
Could not find schema information for the element [URL].NetConfiguration/v2.0:configuration'. and to resolve this i did google again and found a [URL] which is saying to remove that "xmlns" to get error resolved.
In my production environment i am getting below error

i have a fileupload control from which i need the path of a text file. After selecting the file,i need to open the file for reading the data from the text file.For this, i used the following code to open the text file.
fp=File.OpenText(FileUpload2.PostedFile.FileName)
This is working fine in my system.The FileUpload2.PostedFile.FileName statement gives the path of the file.The File.OpenText method opens the selected file.But when i run my project in IIS,it gives the following error:
"File.OpenText is not declared."
The FileUpload2.PostedFile.FileName statement is not retrieving the path, it retrieves only only the filename.what could be the reason?
I try to follow the MVC tutorial: [URL] but in section "Listing 2 - ViewsHomeIndex.aspx"

View 3 RepliesCan you do something like :
<%# DataBinder.Eval(Container.DataItem,"Column1").ToString().Replace("_",<%# DataBinder.Eval(Container.DataItem,"Column2") %> %>
Can a DataBinder.Eval be nested within another DataBinder.Eval?

I am trying to access column value by using DataBinder.Eval on RowCommand event of Gridview. It always return NOT SET TO ANY INSTANCE error for eveytime. I know how to do this by employing a label control in ItemTemplate, but am trying to find a way to bypass.

I'm working on converting the TailspinSpyworks shopping cart Joe Stagner wrote in C# to VB using an evaluation version of VS 2010. I have the following public function:
Public Function GetShoppingCartId() As [String]
If Session(CartId) Is Nothing Then
Session(CartId) = If(System.Web.HttpContext.Current.Request.IsAuthenticated, User.Identity.Name, Guid.NewGuid().ToString())
End If
Return Session(CartId).ToString()
End Function
For Session in Session(CartId) I'm etting the following error: 'Session' is not declared. It may be inaccessible due to its protection level. For User in User.Identity.Name I'm getting the same error: 'User' is not declared. It may be inaccessible due to its protection level
Maybe I'm going crazy or I need some sleep, but I'm trying to use the brilliant membership feature in ASP.NET, and I want to check if the user is currently logged in. The code I got from the book is:
[Code]....
I keep on getting this error: " 'User' is not declared. It may be inaccessible due to its protection level." I noticed it's not even in the code hints that Visual Studio provides. Maybe I need to import a namespace or something, but right now I'm at a loss.
So I have a matser page with a few images that I added using a normal tag <img src="../../Content/logo.jpg" alt="" />. This works fine while debugging on localhost, but the images won't show up when I view the page from the live application. Someone mentioned using URL.Content, but when I added that to my tag I received a "Name URL is not declared" error.
View 9 RepliesI'm working at the aspx page, and the following code is inserted in a Repeater control:
<%# ((System.Collections.Generic.List<double>)DataBinder.Eval(Container.DataItem, "BookPrices")).Max() %>
Brings up the following error: 'System.Collections.Generic.List<double>' does not contain a definition for 'Max'
List does have an method of Max(), so I'm possibly messing up my code somehow. What is my problem?
BookPrices is a list<double> object, which I'd like to print it's maximum value.
I've a asp.net linkbutton inside asp.net repeater control which renders multiple link buttons. I want to set the style of each and every linkbutton dynamically.
I'm trying
style="color:#6D7B8D;font-size:<%# DataBinder.Eval(Container.DataItem, "Title")%>;"
But i'm getting "The server tag is not well formed" error.
I have the following object:
CrossTabDataObject
{
string RowName{get;set;};
int RowId{get;set;}
List<string> CellContents = new List <string>();
//Constructor..... etc.
}
I'm building a dynamic crosstab grid using GridView in asp.net 3.5
I wish to bind to CellContents[0] for dynamic column 1, CellContents[1] for dynamic column 2 (dynamic column 0 is the RowName field from the CrossTabDataObject) etc. I am using:
object boundValueObj = null;
Control ctrl = (Control)sender;
IDataItemContainer dataItemContainer = (IDataItemContainer)ctrl.NamingContainer;
boundValueObj = DataBinder.Eval(dataItemContainer.DataItem, strSelectedID);
This code is in the InstantiateIn function of the gridview as I'm creating drop down list templates in each cell of the crosstab.
I have code (not shown) that sets strSelectedID depending on the column being created.
When strSelectedID is equal to "RowName" for dynamic column [0] the DataBinder.Eval function works fine and sets boundValueObj as expected. The problem comes when strSelectedID is set to "CellContents[n]" where n is the Column Index.
DataBinder.Eval only works with properties and fields of objects. How do I get around this?
i have one hidden field and i want to bind it with two values of my data base separated by an coma. some thing like
->asp:HiddenField ID="hfRstidDate" runat="server" Value=<%# DataBinder.Eval(Container.DataItem, "tsk_ID"),DataBinder.Eval(Container.DataItem, "Date_Worked").ToString())%>
<asp:Label ID="lbl_date" runat="server" Text='<%# Convert.ToDateTime(Eval("dt_pub")).ToString("dd/MM/yyyy") %>'
check for systax error
It show me server tag not well formed error
