What object should I use - Gridview won't work

Posted By:      Posted Date: October 13, 2010    Points: 0   Category :ASP.Net

Hi All.

I would like to create a gridview that gets data from a datasource but doesn't display it in the normal fashion based on my table layout.


Table layout is:

Name     Emp#     Dept#     Booking Code#     AccessId

This is how it looks in the gridview but I would like it to look like:

Name:                     John Doe                               Dept#:                   12

Booking Code#:      1234                                     Booking Code#:     67

How to find specific nested object type in Gridview

Gridview row sometimes has to be selected twice for code to work


I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.

For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.

Can anyone tell me why I have to click twice for some rows? And how do I fix this?

Thank you

    //// Get the currently selected row using the SelectedRow property.
    GridViewRow row = GridView1.SelectedRow;

    txtMonday.Text = (row.Cells[7].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtTuesday.Text = (row.Cells[8].Controls[0] as DataBoundLiteralControl).Text.Trim();

Getting Access Denied when trying to work with PrintQueue object


I have client app that I am working on that is supposed to be able to manage print queues, such as resuming print jobs or purging jobs that have hung up.  The problem I am running in to is that I need to open the queue with appropriate rights to do that management.

I am using the line  below to create the queue.

pq = new PrintQueue(ps, printQueue, PrintSystemDesiredAccess.AdministratePrinter);

However, this line returns an access denied.  I am an admin on the local box, so I can't image why I am having this issue.

If I open the queue like this:

pq = new PrintQueue(ps, printQueue);

The open works find, but when I try to access the jobs in that queue, I get the access denied message.

Any idea what I am doing wrong here?  Any help would be greatly appreciated.

Nested GridView Control returns "Object variable or With block variable not set" when outer GridView


Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.

The Nested GridView Control works as long as the outer GridView returns rows, the following code works:


Protected Sub GridViewReport_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewReport.RowCreated

          If e.Row.RowType = DataControlRowType.DataRow Then

                 Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)
                 If Not e.Row.DataItem("Status_ID") Is Nothing Then
                                  myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
                 End If

Gridview - Object Reference not set to an instance of an object - on rowupdated


I've already found the solution to this problem but I am posting here in case others bang their heads for too long before trying the simple fix. 

I have a gridview that on rowupdated I am capturing in a log the text from 2 columns.  What I tried was:

   Protected Sub IowaCompletedGrid_RowUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdatedEventArgs) Handles IowaCompletedGrid.RowUpdated
      Dim s As String = e.Keys("TaskID").ToString & ": " & e.Keys("Task").ToString

 End Sub

But that throws the 'Object reference not set to an instance of an object.' error.  Here's the weird part:  if you move the e.Keys("Task").ToString to it's own variable and then add them together, it works fine.

   Protected Sub IowaCompletedGrid_RowUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdatedEventArgs) Handles IowaCompletedGrid.RowUpdated
      Dim s As String = e.Keys("TaskID").ToString & ": "
      Dim sT As String = e.Keys("Task").ToString
      s = s & sT

' ...etc
 End Sub

my problem with all of this is why does it matter where I assign the e.Keys reference?  In my first examp

COM Object Interop DLL generated on Visual Studio 2010 does not work on 64-bit system



When I add a COM object Example.dll as reference, it will automatically generate a file called Interop.ExampleLib.dll to my bin folder. It works fine on 32-bit system but when I try it on a 64-bit my program fails to run.

I replaced the Interop.ExampleLib.dll with one that I generated a while ago using Visual Studio 2008, and it works on both 32 and 64-bit system.

Anyone knows what's the problem?

Thanks in advance!

Bind gridview column to nested object



not really sure how to phrase this question.

If I have a list of contacts List<Contact> and a Contact object has an Office object property, I want to display a grid with columns

Contact Id, First Name, Last Name, Office Name

Where the sources of the above columns are respectively:

Contact.ContactId, Contact.FirstName, Contact.LastName, Contact.Office.OfficeName

I'm fine with binding the first 3, but was wondering whether I can bind the OfficeName using either Bind or Eval or whether I need to hook into the events and set the value there.
