Someone know the answer?. I thought I was right to use Eval.
I am stuck with a problem. I have a product page which consits of 2 content place holders. in one of them there is gridview bounded with produtcs and in the other there will be dynamically generated checkboxes used to filter the grid view. upon clicking a checkbox the gridview is filtered showing the products that match the checkbox criteria AND the checkboxes must also be filtered so that checkboxes which were available for previous products should be deleted.
I am loading the checkboxes in the page load. When I enable viewstate for the checkboxes I get the following error:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
when I disable the viewstate of the checkboxes I get the following error:
An error has occurred because a control with id 'ctl00$refineProducts$ctl04' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

I have created web method for "getting contacts".
My parameters are UNAME,PWD,VerticalID and Filter, now, there is no problem with my uname,pwd and verticalid, but my Filter have value of A,B,etc.in the sense just one character value.
But whenever I entered data,it returns this error:
"Specified Value has invalid CRLF Characters" this error belongs to Filter.
But when I entered ABCD it returns null because Filter is a string type and only one character value. But ASP.NET is not taking this one character value as string.

I have two drop down lists and a upload control. One dropdown allows my user to select a valid contract number, and the second dropdown is populated from a table that has 5 contract document types and id's.
after i use the dropdowns to select the information i want and select the file i want to upload based on that information, I press my upload button and get " Invalid column name 'ContractDocumentType'."
It is very possible that I have extra code in here that is not necessary as I have fixed several issues before this one, such as a convert varchar to int error.
What Contract Number Are These Documents Related To?
<asp:DropDownList ID="lstContractNumber" runat="server"
DataSourceID="dsdContractNumbers" DataTextField="ContractNumber"
DataValueField="ContractNumber">

<asp:SqlDataSource ID="dsdContractNumbers" runat="server"

I've got a detailsview control on a page. The table that it interacts with has a DateTime column in it. This column is nullable, and a lot of the records have null for that value. In the EditItemTemplate I've got a calendar control. When I try to put the DetailsView into edit mode, I get the following error message:
System.InvalidCastException was unhandled by user code
Message=Specified cast is not valid.
Source=App_Web_srpmlyjd
StackTrace:

at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
at System.Web.UI.Control.DataBindChildren()
I am convinced that the problem is the null values in the DateTime column of the table. I've done some web searches on this, and some have suggested placing some dummy values into that column, but that seems more like a kludge, rather than a solution. How do I keep nulls in the table, and yet not have that preceeding error come up when a user tries to edit the selected record?
I have a listivew that is assigned a datasource in the code behind based on query string options. From what i have found out, once there is no datasource assigned in listview html then the sort feature stops working automatically and you must put the code in the _Sorting event. I cannot find a good example of this logic.
good example of the listview manual sort logic?

I have a SQL Server 2005 database which is queried by a web service which is called by an aspx page.
I inherited a messy and inefficient project, and I was working on cleaning up a GridView by making it dynamic and by having consistent field names in the database when I started getting an error of - Sys.WebForms.PageRequestManagerServerErrorException: Invalid column name: 'ASSIGNED_TO'
Assigned_to does not exist in the database, in the web service, or in the website solutions in any place. It was the name of one of the fields in one table, which I changed to USERID so that either of two datasets would fit into a Gridview (all other fields were the same). I then replaced all references of ASSIGNED_TO with USERID, which is when the issues began. The first of the two queries below causes the exception to be thrown, but the second one does not. I have tested both with the WCF Client and with a query within SQL Server to verify that they do work, so the issue has to be on the website side.
sSQL = "select distinct B.BADGE_NBR, a.REGId,B.CYC_RTE, b.USERID, a.MTRREAD,A.NEWMTRNUM, a.COMPTIME, B.FA_TYPE, CASE WHEN A.MTRCOMMENTS <> 'Null' THEN '*' END as Comment,a.MTRLAT,a.MTRLONG,a.WOFAID, b.ADDRESS, a.MTRREADFLAG, b.ROUT_SEQ from MobileDataReturn a,WORKORDERDIPATCHFILL b Where a.RegId = b.REGID and a.WOFAID = b.FA_ID and B.CYC_RTE " & route & "' and b.USERID " & worker & "' and B.BADGE_NBR " & badge & "' and a.MTRREADFLAG " & readflag & "' and b.FA_TYPE " & fatype & "' Order by a.COMPTIME desc"

I have a Customer controller that deals with customer products, information and what not. Some products have specialisations that I want handle slightly differently so need a process of doing that. Currently I have hard coded in if statements to see if a customer has that product or not, and if it has, it'll add the extra navigation elements etc.
What I think might be a better way is to have a Controller that inherits off my customer controller but adds the extra functionality. It'd then be pretty nifty if I could, upon receiving the request, check which Customer derived controller has a function that matches the request i.e. ViewSpecialProduct and then invokes that as opposed to the vanilla customer controller.
Are there easier ways? If not how do I accomplish the above? I don't know enough about routes and the controller initialisation process yet.
