ASPX Controls for k2 blackpearl

I'm working on a new control to add to the library called K2Panel.  This control will work with K2Submit.  Add a K2Panel to the page, then you can add standard ASP.NET controls to the panel.  If the ID of the control matches a K2 activity or process level variable, the panel will take care of moving data back & forth between the workflow and controls.

 Design question:

The developer could attach a numeric K2 field, like decimal to a textbox control.  Who should be responsible for validating the user entry?  Should the K2Panel validate the data entered is valid for the datatype?  Or should that be left to the developer?  Remember, the K2Submit control already fires a validate event that allows the developer to do any edit validation.

 Please let me know what you think.

I would agree - leave the developer to validate their own field, especially if there is an event for that anyway.

 Or, I suppose there might be a third option - both. The K2Panel makes sure that the data isn't something really wacky, like text into decimal, but that the developer still has the option to validate that the value is one they'd expect.
 

Saleh,

Are you asking how to start a workflow using the aspx controls for blackpearl project in blackmail?  Sorry, I didn't include that feature in the project.  Right now it can only be used in client events.  That should be a relatively easy feature to add, but I just haven't had time.  Here is some sample code you could use to start a workflow:

  SourceCode.Workflow.Client.Connection  conn = null;

        try
        {
            conn = new SourceCode.Workflow.Client.Connection();
            conn.Open("blackpearl"); //get from web.config

            SourceCode.Workflow.Client.ProcessInstance pi = conn.CreateProcessInstance("HardwareApprovalProcHardware Approval");  //web.config

            pi.DataFields["somefield"].Value = "some value";

            conn.StartProcessInstance(pi);

        }
        catch (Exception)
        {

            throw;
        }
        finally
        {
            if (conn != null) conn.Close();
        }

Hi Geek,

Did you use ADO.NET SqlDataProvider to retreive the actions?

Or you are using code?

I sometimes had problem with the Provider methods and simply use code:

(please make sure web.config has specified <identity impersonate='true'>

and using windows authentications)

  if (!this.IsPostBack)
        {
            string SN = Request.QueryString["SN"].ToString();

            using (Connection k2nn = new Connection())
            {
                k2nn.Open("BlackPearl");

                WorklistItem wli = k2nn.OpenWorklistItem(SN, "ASP", false);

                DropDownList1.DataSource = wli.Actions;
                DropDownList1.DataTextField = "Name";
                DropDownList1.DataValueField = "Name";
                DropDownList1.DataBind();

               //Display K2 datafileds or SmO data here....
                   k2nn.Close();
            }
        } 

I am also having this problem merely running the downloaded source code for this project. It looks like it's looking for a serial number in the URL of the when the project is run, but no serial number is supplied. What number should be put in there?

Thanks,

Kim

Hello Again,

I have a case to use your control again, but this time I'd prefer to not have the screen reload and say "Activity Actioned" down by the control. Instead I would like to redirect the user to another page. I tried putting a redirect in SaveWorkflowFields as you will see below, but the activity does not get recorded if I redirect there. Any advice?
