Debugging dynamically loaded controls

Hi
I am working on this legacy VB.NET 2003 application that loads controls dynamically.

Problem is that some of these controls also load nested controls dynamically...and then I can't seem to be able to debug them. The bug I am trying to fix is in one of these controls...lucky me.

Is there something I am doing wrong?

Controls are loaded in the similar way in 2005.. Only thing is that the designer is hidden from the developer. There are .designer file associated with 2005 which holds those.

If the control is added without source, you cant go to the source to debug.. as we cant go F11 to see what is written inside FileInfo object...

If those controls are created by yourself, include the pdb file and add the dll directly with debug symbols. I think you can debug.

Or let us explain what exactly the problem, so that we could help something to fix. Rose | [Rose]

How to insert/update a row/cell in datagrid?

skhan173-Sep-09 7:32

I don't understand how to update the row into the Datagrid to display a specific date format ??

[ds is my dataset]
foreach (DataRow r in ds.Tables[0].Rows)
{
     string dateString1 = r["First_Resurvey_Date"].ToString(); 
    DateTime dateTime=Convert.ToDateTime(dateString1);
    string [] dateStringArray= dateTime.GetDateTimeFormats();

    r["First_Resurvey_Date"]= dateStringArray[6]; [This doesn't work, I cannot just assign the specific value to a datagrid row/cell......I need help on how to do that] [dateStringArray[6], gives the date format as dd-MMM-YY, which is how I want to display my date in the application]
                       
    NotesLabel.Text= dateStringArray[6];
    NotesLabel.Visible=true;
 }
DataView view = ds.Tables[0].DefaultView;
resultsDatagrid.DataSource = view;
resultsDatagrid.DataBind();
resultsDatagrid.Visible = true;

RTFM

This does nothing but attempt to assign the value if the 5th element in the array to the column, it does not do any date formating.

string [] dateStringArray= dateTime.GetDateTimeFormats();<br />
r["First_Resurvey_Date"]= dateStringArray[6];

To format a date you need to do something like DateTime.ToShortDateString or DateTime.ToString(...)

If you have read the code correctly, then you should notice that I have a string type 'dateString1' variable, which holds the string value of a date type data row from the datagrid[string dateString1 = r["First_Resurvey_Date"].ToString(); ]. My understanding could be wrong.

And then there is a DateTime type variable 'dateTime', which holds the DateTime type value of the String dateString1.[DateTime dateTime=Convert.ToDateTime(dateString1);]. And then the string array dateStringArray contains various date formats of the 'dateTime' variable from which I need to display [6].[string [] dateStringArray= dateTime.GetDateTimeFormats(); ] I do understand that the formatting doesn't change the datarow from the datagrid.

Now once I have got a specific format of the date I want to display to the user, I was looking for a way to display that specific format into the datagrid. Please let me know if there is any way to do that, I hope I conveyed correctly what I want to do.

Thanks in advance.

You where not clear in what you were asking for. This appears you are asking how to format a date

skhan17 wrote:
r["First_Resurvey_Date"]=

Nor is it clear for this context that you want a format and not a date. The name seems to imply a date.

Override the DataBind event and set the value of the column directly rather trying iterate through the DataTable and change the value.

AFAIK ASP.NET does not translate ~ into your root web application path when used within the defaultUrl attribute.
You can most likely be able to replace it with /exxnew/PresentationLayer/Forms/Main.aspx (where /exxnew denotes your prod website's virtual root path)

Setting x-microsoftajax: Delta=true header is giving http error 400

Are you using XmlHttpRequest for this??

I think what asp.NET does... from within the updatepanel.. if a request is made. the postback is suppressed and AJAX page creates an XMLHttpRequest object and places the special request with x-microsoft: Delta=true and receives only the part of data which corresponds to the update panel..

This is purely an AJAX request and the output you get from those request will not hold the entire page. If are putting your custom request by making an object of XMLHttpRequest yourself, you need to know what are the other things that the request must contain before this could get an output. This is purely a custom request made by Microsoft. 400 means bad request or Page doesnt exists...

Thus rather than making this type of request, it is always better to expose the data in one page and make a call normally to it. Tweaking between custom forms and viewstate entries is not always good... (At least who knows this internal form structure might change in next version of UpdatePanel)

Hi Abhishek,

Thanks for the reply..
but what about it "but if i remove this header(x-microsoftajax: Delta=true ) i get the page but without that updatepanel which contains the required data for me....."

Yes i am using HTTPRequest object.
so as you said i should try to send httprequest without view source and other stuff but can you explain it a bit more that what i should exactly do.

Thanks A Ton

This really isn't related to ASP.NET, it would probably be more appropriate in the C# or .NET Framework forums.

However, you can try something like this
baContact.BusinesTypeReference.EntityKey = new System.Data.EntityKey("Entities.BusinessType", "ID", businessTypeID);

Edit I think it was because the baContact is null. It hasn't been inserted into the database yet.

SqlData.BusinessAssociateContactChangeRequest baContact = new BusinessAssociateWorkFlow.SqlData.BusinessAssociateContactChangeRequest();

How can baContact be null? It doesn't matter if it inserting into the database or not at this point.
