Call a master page Method() from content page using c#

In the Master page code behind file define the method you want to call as Public.

public partial class MasterPage : System.Web.UI.MasterPage
{

public void ShowLicenseErrorImage()

this.IMG_LicenseExceedWarn.Visible =
this.lblLicenseMisuse.Visible =
this.lblDetails.Visible = true;
}

public void HideLicenseErrorImage()
{
this.IMG_LicenseExceedWarn.Visible =
this.lblLicenseMisuse.Visible =
this.lblDetails.Visible = false;
}

}

Now in the content page code befind type the following.

MasterPage master = (MasterPage)this.Master;
master.ShowLicenseErrorImage();

Where “MasterPage” is the class name of class in master page.

Get list of folders inside a sharepoint document library

After doing a long search in net, I found a method to get the folder lists inside a document library. It cannot be achieved using a windows sharepoint webservice instead we should use frontpage RPC methods. List documents is one such method that will return the list of folders and documents inside a document library. But the return value will be in the HTML format. So i filtered only the folder names from it. Below i am giving the code snippet. This might be useful for you folks.
