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())%>
Can anyone explain me that what is the diff between DataBinder.Eval Vs DataBinder.GetPropertyValue?
View 2 RepliesI have the code below that works fine, but I need to have more than one field using the same command.

I have a hiddenfield in my datalist .....and its databinded like this
<asp:HiddenField ID="SecondLevelCategory" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "SecondLevelID") %>' />
the problem arise when this datacolumn in my database have a null value, it throws an error ....how can I get this to work so that DataBinder.Eval can take a null value?
Can 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 have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :
[code]...
As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.
I got the difference between Bind and EVal from here. Bind will do both way reading and writing. And Eval do only reading. So any function only for writing?
View 1 RepliesI'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 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.
Error returned by DataBinder.Eval(row.DataItem, "LinkToInvoice").ToString

I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the
tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
