IT Hit WebDAV Ajax Browser Custom Columns - ithit-ajax-file-browser

Question

I am looking at a trial of the Ajax Browser Control by ItHit. So far it seems to be pretty responsive when it comes to pulling files across http protocol.
What I want to do at this point is have the details view pull custom properties from my excel workbooks. What is the most efficient way to connect my C# code that gets the custom properties to the Ajax control to display the correct values?

Answer 1

The easiest way to create a custom column is to return custom property from a WebDAV server. In the example below the server returns price in PricesNs:RetailPrice property.
On a client side you will define a custom column and specify custom property name and namespace:
{
Id: 'MyColumn1',
CustomPropertyName: 'RetailPrice',
CustomPropertyNamespace: 'PricesNs',
Text: 'Retail Price',
Width: '150px'
}
Another approach is to return an HTML from a Formatter function specified for column. You have a full control over what is being displayed in this case.
You can find more details and an example in this article: http://www.webdavsystem.com/ajaxfilebrowser/programming/grids_customization/
In case your WebDAV server is running on IT Hit WebDAV Server Engine, to return the requested property, you must implement IHierarchyItem.GetProperties method (or its asynchronous counterpart):
public IEnumerable<PropertyValue> GetProperties(IList<PropertyName> names, bool allprop)
{
if (allprop)
{
return getPropertyValues();
}
List<PropertyValue> propVals = new List<PropertyValue>();
foreach(PropertyName propName in names)
{
if( (propName.Namespace == "PricesNs") && (propName.Name == "RetailPrice") )
{
// Depending on the item you will return a different price,
// but here for the sake of simplicity we return one price regerdless of the item
propVals.Add(new PropertyValue(propName, "100"));
}
else
{
...
}
}
return propVals;
}
