Validating Silverlight Xaml With Commandline Tool
Mar 3, 2011
We generate xaml in .net4 framework module with the help of an xmlwriter. We want to be sure that the xaml is working properly in the silverlight application we use it in. To test the generated batch of xaml file we want to have a commandline tool that validates these files. How can we use the xamlreader to validate this, or are there any other ideas how to do this? In the current solution we use the XamlReader but if gives to following exception:
'Cannot create unknown type '{clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls}TreeView'.'

As ASP.NET MVC has a pluggable view engine architecture, and XAML is an object descriptive mark-up that, given the right processor/ parser, can generate an appropriate UI...are there plans/ efforts to create a view engine that can turn XAML into HTML?
Personally, I think this would help to re-enforce the efforts the WPF/ Silverlight people have gone to in providing a means of seperating the view from the model/ business logic between designers and developers (via Visual Studio and Expression Blend)...
Seems like a logical step to me, but not knowing XAML as well as I should, I'm wondering if feasable, or even relevant.

I am trying to understand this example. My issue, is can I save a .xoml/.xaml definition to the database the same way you save an xml file? Or do I have to convert this file to something else?
This is the .xoml that gets re-written with these values. The file that is generated as part of a wizard step.
[Code]....
This .xaml gets generated from this code.
try
{
// Save the workflow first, and capture the filePath of the workflow
this.workflowDesigner.XamlFile = "CustomOutlookWorkflow.xoml";
this.workflowDesigner.PerformSave();
this.xamlFile = this.workflowDesigner.XamlFile;
XmlDocument doc = new XmlDocument();
doc.Load(this.workflowDesigner.XamlFile);
XmlAttribute attrib = doc.CreateAttribute("x", "Class", "http://schemas.microsoft.com/winfx/2006/xaml");
attrib.Value = this.GetType().Namespace + ".CustomOutlookWorkflow";
doc.DocumentElement.Attributes.Append(attrib);
doc.Save(this.workflowDesigner.XamlFile);
compileWorkflowButton.Enabled = true;
MessageBox.Show(this, "Workflow generated successfully. Generated Workflow XAML file:
" + Path.Combine(Path.GetDirectoryName(this.GetType().Assembly.Location), xamlFile), this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch
{
generateWorkflowButton.Enabled = true;
}
public void PerformSave()
{
if (this.XamlFile.Length != 0)
{
this.SaveExistingWorkflow(this.XamlFile);
}
else
{
SaveFileDialog saveFileDialog = new SaveFileDialog();
saveFileDialog.Filter = "Workflow XAML files (*.xoml)|*.xoml|All files (*.*)|*.*";
saveFileDialog.FilterIndex = 1;
saveFileDialog.RestoreDirectory = true;
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
this.SaveExistingWorkflow(saveFileDialog.FileName);
this.Text = "Designer Hosting Sample -- [" + saveFileDialog.FileName + "]";
}
}
}
internal void SaveExistingWorkflow(string filePath)
{
if (this.surface != null && this.loader != null)
{
this.loader.XamlFile = filePath;
this.loader.PerformFlush(this.Host);
}
}
Ultimately a .dll is compiled and will be saved, but I would like to be able to save the xaml definition to the database. I hope this is easily converted to an enterprise solution but it is looking to be alot of work.
// Compile the workflow
String[] assemblyNames = { "ReadEmailActivity.dll" };
WorkflowCompiler compiler = new WorkflowCompiler();
WorkflowCompilerParameters parameters = new WorkflowCompilerParameters(assemblyNames);
parameters.LibraryPaths.Add(Path.GetDirectoryName(typeof(BaseMailbox).Assembly.Location));
parameters.OutputAssembly = "CustomOutlookWorkflow" + Guid.NewGuid().ToString() + ".dll";
results = compiler.Compile(parameters, this.xamlFile);
StringBuilder errors = new StringBuilder();
foreach (CompilerError compilerError in results.Errors)
{
errors.Append(compilerError.ToString() + '
');
}
if (errors.Length != 0)
{
MessageBox.Show(this, errors.ToString(), this.Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
compileWorkflowButton.Enabled = true;
}
else
{
MessageBox.Show(this, "Workflow compiled successfully. Compiled assembly:
" + results.CompiledAssembly.GetName(), this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
startWorkflowButton.Enabled = true;
}

I need to display current status of a document approval workflow task in asp.net web page with a specific activity highlighted.
I have seen the Visual workflow tracker example (in wf & wcf samples) but I have two issues,
I have to render workflow in asp.net not in a WPF app. I don't need to display current status with workflow running, all activities that need to be highlighted are the ones that require user input. e.g. "waiting for approval from department head" etc.
If I could just convert the workflow XAML to JPG after highlighting a specific activity by activity id "that created a bookmark and waiting for resumption the bookmark" it would do the work.
check the attached file for required workflow image to be rendered on asp.net page:
Workflow with current activity highlighted (that is waiting to be resumed)

I'm following along with Nerddinner making a few changes, and can't figure out why my Create form is not validating. I'm using Linq to SQL and trying to use Modelbinding to map my form data automatically. Using the code below, I do not receive any validation errors on the page, but can't make it past my try{} block. When unhandled, the error I receive tells me I'm unable to insert a Null value for "basetype". This is correct based on Database constraints, but why am I receiving exceptions, and not the nice red error messages and validation?

I'm using a DataGrid with edit functionalities in my project. It's handy, compared to having to edit its source data manually, but sadly, that means that I'll have to deal with validating user input a bit more.
And my problem is basically just that. When I set my DataGrid to EDIT mode, modify the values and then set it to UPDATE, what is the best way to check if a value that I've entered is, in fact, compatible with the corresponding column's data type?
i.e. (simple example)
// assuming
DataTable dt = new DataTable();
dt.Columns.Add("aa",typeof(System.Int32));
DataGrid dg = new DataGrid();

I have a textbox that the user is suppose to enter a valid user name , the valid user names are stored in database. for example the valid user names might be U100, U101, U102 ,U103,U104,U105,U106,U107. so if the user types anything other than that he should get a error message and I dont want to implement a drop down list for that , how to do this in asp or should i explore javascript for this.

I've got a View where I allow input, the fields are set as float in my SQL Server 2008 R2 database and I am using Entity Framwork 4. In the Entity Framework Model the field looks like this private Nullable<global::System.Double> _TestNumber;
And the View uses an EditorField to allow input like this:
<div class="editor-field">
@Html.EditorFor(model => model.TestNumber)
@Html.ValidationMessageFor(model => model.TestNumber)
</div>
I am however getting this error in the Validation Message: The value '13.51' is not valid for TestNumber. I've tried with a comma instead of period, same thing.

I am following this tutorial : [URL]
I am where you "Create" an entry in the table, i have deleted the Id field, as Id is my primary key, and Is Identity = Yes, Identity Increment = 1, Identity Seed = 1.
When i hit the create button, the Id value is being validated, giving an invalid error. If i add the Id column back to the page, and fill in any number and click create, the entry is added to the database, with the Id value incremented (the typed in value does not matter). I believe this must have to do with the Movies.Designer.cs... but not sure how to fix it. Id should not be validated as it auto-incraments, but the model is looking for a Id value..

I developed a screen in which there are fields like first name,username,password and email. I validated these fields using javascript and came to know that javascript is not that safe. So i decided to validate on server side also. My question is whether i can use asp controls like requiredfieldvalidator, regularexpression validator to validate the form or i have to validate through server side coding??

When i use RequiredFieldValidator for Validation FCKEditor ,The first time that the form gonna submit, RequiredFieldValidator prompt (ErrorMessage) and indicate that FCKEditor is empty ,while it isn't .Again if you try to submit the form,It's OK and there is no problem .At this case user have to hit the submit button twice So i have to disable Client Side validation and validate form just in Server Side code which is not good.
