Hi there, another ListObject woe I'm afraid.

I've a listobject, I bind it to a System.Windows.Forms.BindingSource which has an array of objects as its datasource. I have a test setup so that when I click a button it changes the array the bindingSource is bound to. So it alternates between an array of size 5, and an array of size 1000 (so if I keep clicking the button the listobject alternates between having 5 rows of data and 1000 rows of data).

However, when it binds to the 1000 rows the scrollbar at the side gets smaller, as you'd expect. When it binds on the next button click to 5 rows the scrollbar stays the same size, thus making it hard to scroll precisely. If I bind to 1000 rows again (another button click) the scrollbar gets even smaller. In fact the more times to bind to the 1000 rows the smaller and smaller it gets, such that if you bind to say 100 rows that needs alittle scrolling its very difficult to do this with any accuracy as the scrollbar by this point is very sensitive.

I can't think why it keeps getting smaller, or find any way of resetting its size. I've tried deleting all rows from the bottom of the listobject to the bottom of the Worksheet, but it doesn't change anything.

Strange problem, hope someone might have some idea.

Thanks very much.

Hi,

I have an object called Product and that product as a property of type List<Photo>. Photo is an object with an URI and a few more properties. What I want to do is in the DataTemplate access the first Photo of each product. I have something like this for the other properties in the Product Object:

<GridView x:Key="gridView" AllowsColumnReorder="True">
<GridViewColumn Header="Tipo de negocio"
DisplayMemberBinding="{Binding Path=TypeOfBussiness}"/>
<GridViewColumn Header="Tipo de imovel"
DisplayMemberBinding="{Binding Path=TypeOfProduct}"/>
<GridViewColumn Header="Tipologia"
DisplayMemberBinding="{Binding Path=Typology}"/>
</GridView>

And I wanted to define another GridViewColumn to show the photo, that will be in a data template. The problem here is binding to the path provided in the first Photo object of the List<Photo> in Products.

Thank you

Hi,

I got problems with connector inheritance (i'm using the RTM bits).

Suppose I start from the Task Flow template.

I add a connector MasterConnector that becomes the base class for the CommentConnector.

When I create an instance of the CommentConnector (I associate a comment to a task), save the diagram and reopen it, the instance of the CommentConnector has doubled (two lines appear instead of one).

Has anybody noticed the same problem

Thanks!

Mike

help urgently required.

I have attempted to run a CognosController.Msi file but the installation failed with the following error: "There is a problem with this windows installer package. A script required for this install to complete could not be run."

I currently have .NET framework 1.1 including SP1 installed.

Any tips on how I can resolve this problem.

Thanks

I created a report that works and displays properly in both the preview tab in the IDE and when previewing it in the running application (using the crystal report viewer control in a windows form).

I wanted to use the same report in another project. So, I chose to add an existing item and found the report. The report was added to the project just fine. However, if I run the application and preview the report, bold text and lines are not displayed in it. Oddly enough, if I resize the preview window using my mouse, they suddenly appear, so they are there. If I scroll or do anything else, though, they disappear again. They also don't appear in the preview tab in the IDE.

Any ideas How can I use the existing report

By the way, I'm using VS2005 for this.

Thanks!

Hello,

I have an ItemControl which have its ItemsSource set to a List instance. The ItemsControl's ItemsPanel property is set to StackPanel.

How can I draw a line between the two elements

Thank you,

What should I do to solve this problem. Is there any example of a Entity Framework being called by WCF Service

I'm making a sales contract with the report control, what I want to do is: each time the report is generated, it will import a rtf file ( for terms and conditions ) to the report and show it correctly with the report.

Is there any way I can do this with the report control

Thanks in advacne.
