First time using a dataset instead of a data reader, and I'm trying to fill both a datalist on my page, and set the selected item value for a drop down list. The datalist on the page is displaying properly, but I get this errorClass 'System.Data.SqlClient.SqlDataAdapter' cannot be indexed because it has no default property. when trying to set the selected value for the drop down list. Why can't I get the selected value for the drop down list to work properly?
What i am having trouble doing is set the current parameter to the current row at a specific column like e.row[column index]
For Each trow As TableRow In table.Rows
cmd1.CommandText = "dbo.directway" cmd1.CommandType = CommandType.StoredProcedure cmd1.Connection = conn [code].... Class 'System.Web.UI.WebControls.TableRow' cannot be indexed because it has no default property.
I have built a site and worked fine for me, when I passed to a collegaue to deploy into another site he gets the message in subject.

I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.

I have a datatable for which i'm defining a dataadapter. I'm specifying an updatecommand with sqlparameters for the dataadapter I set the updatecommand's parameters using the following overload:
[Code]....
The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.
I am having a problem about my gridview when it binds to an accessdatasource.
The error appears:
"DataBinding: 'System.Char' does not contain a property with the name 'Firstname'."
Here's my gridview:
[Code]....
Here's my code behind:
[Code]....
The error occurs when the selected index of the DDL is 1 and I have to bind it in an accessdatasource. First condition is working fine where I will check a value and put all items that matched the date criteria in a data table and then bind gridview in the data table.
The error is just when I bind my gridview in the accessdatasource.
AccessDataSource1.SelectCommand = "Select Firstname,Middlename,Lastname,Jobseeker.IdNo,SchDate,Time,Venue,JobPosting.JobCode,JobTitle from JobPosting INNER JOIN (Jobseeker INNER JOIN ApplicationProgress ON Jobseeker.IdNo = ApplicationProgress.IdNo) ON JobPosting.JobCode = ApplicationProgress.JobCode where PostingHr = " & Session("Id") & " and SchDate = '" & Date.Today.ToString("dd - MMM - yyyy") & "' " GridView1.DataSource = "AccessDataSource1" GridView1.DataBind()

what is wrong with this syntax datatable temp = (DataTable)du.Rows[0]["NAME"] I get the error message Unable to cast object of type 'System.String' to type 'System.Data.DataTable'.
I tried translating this from vb but getting the error on e.Row.DataItem("CustomerID").ToString i tried varios things but no gooddbSrc.SelectCommand = "SELECT * FROM Orders WHERE CustomerID = '" + e.Row.DataItem("CustomerID").ToString + "' ORDER BY OrderDate";
I'm getting started with Astoria/ADO.NET Data Services/WCF Data Services. Looking through a lot of the code samples out there, it appears that the MimeType attribute used to be a method level attribute. After installing the latest update, it is now a class level attribute.
If I have more than one Service Operation that I want to return as a certain MimeType, then it appears now that I have to create a new service for each operation. Is this correct?
Most examples are like this:
[WebGet] [SingleResult] [MimeType("application/pdf")] public IQueryable<byte[]> FooPDF() { var result = from p in this.CurrentDataSource.MyPDFs where p.FooID == 2 select p; return result.Take(1).Select(p => p.PDF); }
I get "Attribute 'MimeType' is not valid on this declaration type. It is only valid on 'class' declarations." when I compile, because now I can't do this.
Now, I have to do this:
[MimeType("FooPDF", "application/pdf")] public class FooService : DataService<FooDBEntities> { public static void InitializeService(DataServiceConfiguration config) { config.SetServiceOperationAccessRule("FooPDF", ServiceOperationRights.All); } [WebGet] [SingleResult] public IQueryable<byte[]> FooPDF() { var result = from p in this.CurrentDataSource.MyPDFs where p.FooID == 2 select p; return result.Take(1).Select(p => p.PDF); } }
What's worse is that I can't add duplicate MimeType attributes to my class.
