Adding web part programmatically : Sharepoint

Dear All,

i'm using the following code to add web parts to a page programmatically,
however i've a problem that after the page is postedback the web part is
not visible on the page, i need to refresh the page to get the web part
visible,

appreciate your support.

SPWeb myWebSite = SPContext.Current.Web;



SPLimitedWebPartManager WebPartMgr =
myWebSite.GetLimitedWebPartManager(Page.Request.RawUrl,
PersonalizationScope.Shared);

SPSite s = new SPSite(myWebSite.Url);

SPList WebPartCatalog = s.GetCatalog(SPListTemplateType.WebPartCatalog);

string serverUrl = ""; //tohandle the root url in case of mapped pathes

serverUrl = myWebSite.Url.Substring(0, myWebSite.Url.LastIndexOf("/") );



StreamReader sr = new StreamReader(new
System.Net.WebClient().OpenRead("http://" + s.HostName +"/" +
WebPartCatalog.Items.GetItemById(Convert.ToInt16(drpWebParts.SelectedValue)).File.Url));

StringReader strR = new StringReader(sr.ReadToEnd());



XmlReader xmlR = XmlReader.Create(strR);

string errMsg = "";

System.Web.UI.WebControls.WebParts.WebPart wp =
WebPartMgr.ImportWebPart(xmlR, out errMsg);

WebPartMgr.AddWebPart(wp, drpZones.SelectedValue , 0);

Have you tried redirecting the page back to itself after your code runs?

Yes i did, but then i get the page in the browse mode not in the edit mode,
actually i posted another question in this group asking about how to
redirect to the page in the edit mode.

Thank you for your reply Bryan

regards,
Mohamed

You can redirect to the same page after u finish all ur functionality. You need not to worry about shared mode or Edit mode.

Since you are redirecting to the same page, u have to specify some condition so that page should not go infinite loop in redirction.

You can simply use Query string for the same.

For Example:

if (Request.QueryString["success"] == null)
{
Response.Redirect("/YourPage.aspx?success=1");
}

SharePoint site security helps manage permissions for different resources within a site by defining the levels of accessibility permissions for different peoples and groups. In SharePoint, always the top-level or the parent level permissions are inherited to it's child contents (e.g. a sub-site inheriting permissions from it's parent site collection).In-order to create unique permission we need to break the inheriting parent permission and create new permission level for the SharePoint content. These permissions can be defined for specific users or groups.

Please add on .
Thanks
