Passing custom data to SPWebProvisioningProvider class?

    Hi All,

    How can I pass custom (dynamic) data to a custom provisioning provider? I cannot use ProvisionData because my data is not static which can be stored in an XML file. I need to pass data from a custom application page that provisions site using custom provisioning provider programmatically.

    Any ideas/pointers?

    Thank you!

    Hi

    You should be able to do this by creating a class derived from SPWebProvisioningProvider and override the Provision method.  In Provision(),  you pass in your custom data using the SPWebProvisioningProperties parameter's  Data property. After having called  ApplyWebTemplate inside the Provision method   you can add your   custom logic from SPWebProvisioningProvider to activate features, create lists, sub sites etc. You probably have to do this with elevated privileges.

    Can you please elaborate?

    I need to pass data to my custom provisioning provider which is derived from SPWebProvisioningProvider. In the provision method, I am activating a feature whose receiver expects to find a property in SPWeb object. So, somehow I need to set this property before activating the feature. Another important thing is, the property that I am trying to set should be passed in from an application page which invokes custom provisioning provider.

    Application Page ---> Custom Provisioning Provider ---> Feature Receiver

    So, there is a drop down list in the application page whose selected item's ID I need to pass to application page, then to provisioning provider and then to feature receiver.

    Any pointers?

    Unfortunately, the link that you provided doesn't answer my question on how to pass custom data to provisioning provider from an application page. Am I missing something?

    You should be able to set a querystring variable from your custom application page. Then possibly check in the provision method for HttpContext.Current.Request.QueryString for the ID.

    Can you please let me know how I can set a querystring variable from application page? There is a drop down list in app. page that I would like to pass to custom provisioning provider. Do you mean that I need to set query string after the postback of app. page?

    Can you let me know how you are invoking the Custom Provisioning Provider from your application page. Usually the SPWeb is created first and the template is applied. So are you creating the SPWeb first in your application page?

    THanks the quick reply, Steve. Here is my code snippet which provisions a new site by calling custom provisioning provider's site definition:

    SPWeb newSite = oWebsiteRoot.Webs.Add(clientAccountName, clientAccountName, "Client Account Site for " + clientAccountName, nLCID, "ClientAccountSiteDefinition.CustomProvisioningProvider#0", false, false);

    newSite.Title = this.ClientsDropDown.SelectedItem.Text;
//store clientid in SPWeb property bag for later retrieval in the provisioning process
newSite.SetProperty("clientid", this.ClientsDropDown.SelectedItem.Value);                
newSite.Update();

    As you can see above, I am trying to set a property in the new site but that property is not preserved or I am unable to find that property from custom provider.

    Please let me know if I am not clear.

    Thanks!

    You should be persisting and retrieving SPWeb properties using the AllProperties collection.  You can just add or update a property like this,

    newSite.AllProperties["clientid"] = this.ClientsDropDown.SelectedItem.Value;

    newSite.Update();

    This should be available from your provider by looking at newSite.AllProperties["clientid"]

    My other confusion:

    Line 1 is where provision method of custom provisioing provider is invoked and that is where I am accessing the property. But I am not setting the property until Line 3 by which time provision method would already have been executed? Is my assumption right? I am confused about the order of execution. Provision method is executed on line 1?

    The SharePoint UI provisions the web with a null argument for the template, then calls SPWeb.ApplyWebTemplate

    Still no luck Steve. This is how I am checking for property from Provision method:

                //retrieve current clientid from property bag
            if (props.Web.AllProperties.ContainsKey("clientid"))
            {
                oWebsite.SetProperty("clientid", props.Web.AllProperties["clientid"].ToString());
                oWebsite.Update();
            }
            else
            {
                WriteLogEntry("there is no key");
            }

    In ULS logs, the log message "there is no key" is being logged. Am I missing something?

    This is how I am setting the property:

    newSite.AllProperties["clientid"] = this.ClientsDropDown.SelectedItem.Value;                
newSite.Update();

    Thanks!

    Did you use SPWeb.ApplyWebTemplate and not send in the template argument when calling Web.Webs.Add?

    No, I didn't.

    So, the sequence would be:

    1. add web with null argument.

    2. set property

    3. apply web template

    Does that look right to you?

    Yes, the ApplyWebTemplate method invokes the custom provider and web should have the property persisted by then.

    Steve - I tried the way you suggested but I get an error: A site template has already been applied to this site. Once a template has been applied, the site must be deleted and recreated in order to apply a different template

    Below is the code snippet:

    SPWeb newSite = oWebsiteRoot.Webs.Add(clientAccountName);
newSite.Description = "Client Account Site for " + clientAccountName;
newSite.Title = this.ClientsDropDown.SelectedItem.Text;
//store clientid in SPWeb property bag for later retrieval in the provisioning process
newSite.AllProperties["clientid"] = this.ClientsDropDown.SelectedItem.Value;
newSite.ApplyWebTemplate("ClientAccountSiteDefinition.CustomProvisioningProvider#0");
newSite.Update();

    Please use the code you used before except send in null for the template, Webs.Add(clientAccountName) appears to apply the default template.

    Also, call newSite.Update after calling newSite.AllProperties and before calling newSite.ApplyWebTemplate.

    I am confused Steve. How can I send null for the template? I get compile-time error when I am using the below code:

    SPWeb newSite = oWebsiteRoot.Webs.Add(clientAccountName, clientAccountName, "Client Account Site for " + clientAccountName, nLCID, null, false, false);

    Pointers?

    Sorry, the SharePoint UI calls an internal Add method which can take a null. Instead of null try using string.empty.

    That worked Steve! Thank you so much for being patient and guiding me in the process. Appreciate that.
