• .NET Development problem in using DropDownList Control

  Hi All, I am developing a small web application in 1.1 framework. I am using a DropDownList control. I have coded a selected index changed event for that, and set the autopostback property to true. When i select any value from dropdown, it triggers this event alright, but again displays the 0th value from drop down. What could be wrong. Code Snippet: private void DropDownList1_SelectedIndexChanged( object sender, System.EventArgs e) { DataView dv; Students st = new Students(); dv = st.DataLoad(); dv.RowFilter = "Student = '" + DropDownList1.SelectedItem.Value + "'"; // always returns 0th r ...Show All

• Windows Forms DataGridView DisplayIndex doesn't keep positions

  I have a problem with the DataGridView. I place a DGV on a form and add some databound columns. Then I add some non-databound colums. Then I re-order the columns in the column designer using the up-down buttons. Everything ok so far. But when I run the application, the order of the columns are shuffled. How can this be The only workaround so far, has been to set the DisplayIndex of each column in code. But I would expect the designed column order to stay as designed. Regards Claes Brandt Using that property, I won't have any control over the order of the columns, as they will be autogenerated from ...Show All

• Software Development for Windows Vista Beta2: String-Properties in Custom Activities; Custom themes

  Hi, in Beta 1 it was possible to define 'free text'-input string properties with custom activities which enabled the workflow creator to input any text in the corresponding prop of the activity in the workflow designer. Any DependencyProperty with type(string) enabled this. In Beta2 this definition enforces a total different behaviour in the Workflow Designer - it tries to map it to a Workflow member variable ...

• Visual Studio Express Editions DLL Development for the Web

  Which version of Visual Studio Express would I need to create DLL's for use in websites   I prefer to develop using a tiered approach, keeping most processing code in DLL's.  It appears the VB2005 version supports this, but I wanted to make sure. Port of Dreams - You are right that Visual Basic Express is the product you will need to use to create stand-alone DLLs, even if these will be used in websites.  If you are doing significant development across the boundary between Visual Basic Express and Visual Web Developer Express, you will probably want to consider Visual Studio Standard Edition or higher, which make this pr ...Show All

• Software Development for Windows Vista Dynamically load policyActivity ruleSet

  I’ve created a simple sequential workflow using beta 2.2, a windows test application and an interface for data exchange. The workflow has the following elements: HandleExternalEventActivity, CodeActivity, PolicyActivity and CallExternalMethodActivity, and it works fine. A host raises an event and (HandleExternalEventActivity), the workflow does job and the host gets data back through a method (CallExternalMethodActivity). A hart and soul of the workflow is a policy activity. The first step was to design a workflow and reach a point where my policy activity has a well defined ruleSet. Down the road this policyActivit ...Show All

• Visual Studio 2008 (Pre-release) How to config Proxy generation?

  Hi, My service is passing back a common object shared between server and client by a class library. Can I change the generation so the proxy will deserialize the soap into my common objects rather than container objects. Thanks, Mark Liu Can you please give us more info (some sample code to show what you are trying to implement). Just by using channel factory,we can avoid proxy class and both client and service can share data contract and interface definations. sometimes we can modify svcutil generated code,so if you can give us more info with some sample code,we can explore our options to implement t ...Show All

• Software Development for Windows Vista considerations when designing a new custom Activity

  what additional considerations should we have when creating a new "custom" activity for use in both a Sequential AND State driven workflow asked another way: Do we need to create two different Activities one for Sequential and another for State driven -OR- can we have a single Activity that supports both workflow types LaVinci. In general the same activity should work for both types of workflows. However, State Machine workflows do not allow more than 1 (i.e. the first) activity that implements IEventActivity inside the State activity. ...Show All
