Adding SPTimerJob in a FeatureReceiver

In one of my solutions I wanted to add a SPTimerJob through a FeatureReceiver in the feature. The feature was scoped to “Web”. I got an “Access denied” when I tried to do so. The solution I found, was to create a second feature, which was scoped to “WebApplication”. From within this feature, I was able to create my timer job. But only in FeatureActivated. When I tried to add the job from FeatureInstalled, I got the error that SharePoint did not find the assembly, even if it was installed to the GAC.

Use JavaScript within a SPGridView

The NavigateUrlFormat property of the SPMenuField allows you to specify a Url, which will be called if you click the field in a SPGridView. 1: SPMenuField colMenu = new SPMenuField(); <pre style="padding-right:0px;padding-left:0px;font-size:8pt;padding-bottom:0px;margin:0em;overflow:visible;width:100%;color:black;border-top-style:none;line-height:12pt;padding-top:0px;font-family:consolas, 'Courier New', courier, monospace;border-right-style:none;border-left-style:none;background-color:#f4f4f4;border-bottom-style:none"><span style="color:#606060"> 2:</span> colMenu.NavigateUrlFields = <span style="color:#006080">"WebUrl,AlertID,ListID"</span>;</pre> <pre style="padding-right:0px;padding-left:0px;font-size:8pt;padding-bottom:0px;margin:0em;overflow:visible;width:100%;color:black;border-top-style:none;line-height:12pt;padding-top:0px;font-family:consolas, 'Courier New', courier, monospace;border-right-style:none;border-left-style:none;background-color:white;border-bottom-style:none"><span style="color:#606060"> 3:</span> colMenu.NavigateUrlFormat = <span style="color:#006080">"{0}/_layouts/SubEdit.aspx?Alert={1}&List={2};</pre> 4: colMenu.TokenNameAndValueFields = "</span>WEBURL=WebUrl,ALERTID=AlertID,LISTID=ListId"; With the TokenNameAndValueFields property, you map the grid columns to %xyz%. If you want to use a JavaScript instead, you can do so: 1: MenuItemTemplate editAlertMenu = new MenuItemTemplate("

Configuring Kerberos for SharePoint

Kerberos has some advantages over NTLM. Only with Kerberos it is possible to pass the client credentials (meaning the user who logged himself on to the SharePoint website) to another server. This is important, if you use e.g. my Fileserver Access Webpart and configure it to a share on a server, which is **not** your SharePoint Server. If you want to know more about Kerberos, you can look at Kerberos Explained on the Microsoft Technet pages.

Access Fileserver Data via SharePoint

**Update: ** The Webpart is not (yet) working as expected. Ajax only works for postbacks. The initial load will take longer, if you have many directories. I am working on this… **Update2: ** Almost done! Ajax is working fine. Ajax is registered, so you don’t need to modify the web.config yourself. Todo: Performance. Hang on just a little more. **Update3: ** Done. I have worked on my Webpart. It will now be faster and it is working 🙂

Custom Formatting in a SPGridView

One of the problems with the SPGridView occurs, if you display e.g. the file size of files, and try to sort with this information. The internal value you get from a SPFile of FileInfo Object shows you the length of the file in bytes. This is great if you want to sort this column. But what if you choose to display the long value with the amount of bytes for a file not as the value, but formatted with SPUtility.

Permissions Webservice and the Mask Attribute

With the SharePoint Permissions Webservice you can get the Permissions from a List or Web. The Webservice returns information like this example from the WSS SDK: 1: <GetPermissionCollection xmlns=“ http://schemas.microsoft.com/sharepoint/soap/directory/"> <span class=lnum> 2: </span> <Permissions> 3: "1073741829" Mask="-1" MemberIsUser="False" MemberGlobal="False" <span class=lnum> 4: </span> RoleName=<span class=str>"Administrator"</span> /> 5: "1073741828" Mask="1029638927" MemberIsUser="False" MemberGlobal="False" <span class=lnum> 6: </span> RoleName=<span class=str>"Web Designer"</span> /> 7: "1073741827" Mask="1027801615" MemberIsUser="False" MemberGlobal="False" <span class=lnum> 8: </span> RoleName=<span class=str>"
