Change webpart properties programmatically

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :SharePoint
I am attempting to modify the properties of another webpart when my webpart's button is clicked. The code compiles and runs, and stepping through it shows that the properties do change. However, they don't stay changed. This example attempts to toggle the visibility state, but other properties won't stay changed either. Any help is appreciated.     SPSecurity.RunWithElevatedPrivileges(delegate() { // get the site in this context using (SPSite SiteCollection = new SPSite(mySiteGuid)) { // get the web in this context SPWeb myWeb = SiteCollection.OpenWeb(myWebGuid); myWeb .AllowUnsafeUpdates = true; // Hide/display another webpart. Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager mgr = null; mgr = myWeb.GetLimitedWebPartManager( "default.aspx", System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared); foreach (System.Web.UI.WebControls.WebParts.WebPart myWebPart in mgr.WebParts) { // If this is the webpart we want to modify... if (myWebPart.Title == "Other Webpart Name") { // Toggle the visibility state. myWebPart.Visible = ! myWebPart.Visible; myWeb.Update(); break; } } } });

Advanced Basics: Set Word Document Properties Programmatically


At the beginning of another lovely day of writing courseware in mad pursuit of unrealistic deadlines, I received a frantic call from a business partner. He was at the end of a long consulting project and had several hundred Microsoft® Word documents, all of which required their document properties to be set identically, except the Title property of the document, which was to be based on the document file name, minus the .

Programmatically delete a .webpart file from wpcatalogs folder from an IIS website


We are using a third party wsp in our solution which directly adds the web parts into the web application store rather than the web part gallery(References to them are present in IIS site's wpcatalog directory). We want to remove these web part files so that the users will not be able to add these web parts to pages directly. Or any other modification so that users will not be able to add these directly. Is there a way we can do this programmatically?

How can I change the height of the rows in a document library webpart view to minimize the space bet

In SP2010 documents listed in a document library view (attached as webpart) are quite far from each other (height of each row is too big). How can I change the height that spaces between the documents are limited to a minimum, hence more documents are visible on my screen. (e.g. if I have many documents in my document library and add a webpart to my page that should show all documents, I would see more documents if the height of the row would be smaller (e.g. 16px) and spaces minimized. Moreover how can I make a smaller height for each row the default height?

Drop Down Listbox SelectedIndexChanged Event not firing when I programmatically change selection

I have two drop down listboxes (DDL1 and DDL2).  When DDL1 has an index change, DDL2 then has a refresh of list items based off SQL Server SELECT from a table.  The database isn't the problem.  Everything works perfectly when the user selects a new item manually from DDL1.But in my code, I save the user data from the selection of DDL1 in a separate table.  And then upon rendering of the page (Page_PreRenderComplete), I do a SelectedIndex assignment of the value of what's saved in the db table.  That works just fine, it selects the DDL1 item, but DDL2 is unaffected, as if DDL1's SelectedIndexChanged event isn't called like it would be if manually changed.  How can I get around this?Thanks in advance. :)
