• Windows Forms Default value

  Good Morning: I have a data entry application being developed. I have default values on the input screen whenever the users clicks on the '+' to add a new record. This is currently working now, my defaults are on the SQL Server table, when you add a new record the default values populate the fields on the screen, this is fine. I added another column to the table, set its default value on the SQL Server table side, but when I add a new record, the default does not populate to the table. I think there is another place to set the default value, but I can't remember where or what is involved. Any help appreciated. Mike you can use the Datagridview event: dataGridView1.DefaultValuesNeeded +=new ...Show All

• SQL Server How to: Data Source View diagram export as image?

  Hi, does anybody know if there is simple way in a VS2005 Analysis Services project to export a Data Source View diagram from the DSV designer as an image (.jpg, .png etc...) as can be done via right-click with the class designer I dug through the menu options/customization for this feature but cannot find it. Is this feature available Thanks, Jeff Hi Jeff, Unfortunately, I don't believe an export function exists. The best I've been able to come up with in the past is either using a tool like SnagIt to capture the image or printing it to a file using some sort of image-capture print utility...

• Windows Forms Two-way Databinding does not work with empty Datamember

  I have a List of Strings eg. List < string > myList = new List < string >(); myList.Add( "a" ); myList.Add( "b" ); foreach ( string value in myList) { TextBox tb = new TextBox (); tb.DataBindings.Add( "Text" , value, "" ); this .Controls.Add(tb); } This works fine to display the values of the list in the textboxes. But it does not work for writing back the values to the list. It seems there is a problem if the DataMember property of the DataBinding is empty. If I just use a string object to bind to the text property of a TextBox, it does not work. Only if I have a object where I can set the DataSource and the DataMember for Databinding it also work ...Show All

• Software Development for Windows Vista DynamicPropertiesActivity and Designer Rehosting sample

  Hello, I am trying to host DynamicPropertiesActivity (the one available at http://blogs.msdn.com/ghenap/default.aspx ) inside the Designer Rehosting sample application (presented by Vihang Dalal). The problem I am experiencing is that added dynamic properties do not appear in the property grid. Anyone solved this issue Thanks in advance Edmundas I, too, am interested in a solution to this. I did notice that if you save to an xoml file and then load the file, the DynamicProperties do appear in the property grid. So I am focusing on the differences between adding elements to the collection via serialization and via the dialog. Glenn ...Show All

• Windows Forms Readonly databinding with a business object

  I tried to bind a property of a business object to a TextBox control. I used a BindingSource component to accomplish this task. So far so good :-) The property of the business object is a read only property. I thought that data binding recognize this and set the TextBox control to read only. I was wrong. But it's even worse. If I change the text in the TextBox control I can't leave the focus from the TextBox anymore. The focus is trapped in the TextBox control and the user doesn't get any error message. Is it possible that data binding recognize the read only property and set the bound control to read only Can I prevent the TextBox to trap the focus I think the usability for trapping the focus in a control if the validation ...Show All

• Visual Studio 2008 (Pre-release) Suggestion: Can TextSearch be improved to support to search string of other language?

• Visual Studio 2008 (Pre-release) Importing ZAM 3D model to Sparkles

  Hi I'm just a newbie who recently just started looking into WPF and Sparkles :) I've seen many resources online showing different ways of exporting a ZAM 3D model to Sparkles. One of the very interesting way of doing so is: "Edit > Copy XAML" in ZAM 3D then "Edit > Paste" in Sparkles. Does anyone actually manage to do that successfully I've tried myself but Sparkles wouldn't let me paste my ZAM 3D XAML :( Hi Andy, Please visit the Expression Blend (code name "Sparkle") newsgroup to ask questions about that product: http://www.microsoft.com/communities/newsgroups/en-us/default.aspx dg=microsoft.public.expression.interactivedesigner&cat=&lang=en th ...Show All
