Programmatically adding data to SharePoint List’s Choice column

SharePoint has a column type called “CHOICE”. This column will be useful for presenting one of the field from the following

• Dropdown List
• Radio Buttons
• Check Boxes (To Select Multiple Items)

Consider I’ve a list “Resource List” with following columns

Column Name ------ Type
Resource Name --> Single Line of Text
Languages Known --> Choice (C#, VB.NET, Java, C, C++) – Multiselect

“Languages Known” is the CHOICE field (Check Boxes), to select multiple languages known by the resource.When adding new items to the Resouce List, notice that multiple items selected for the ‘Languages Known’ CHOICE column will be seperated by semi colan(‘;’).

I had a requirement to add the list item by code. I have used “ChoiceA;ChoiceB;..ChoiceN” for storing the ListItem’s multi-select CHOICE field. After adding ListItem by code, I have Edited the newly added item in the browser, but no check box has been selected for the item which was added by code.

Then after a little effort I found that the multi-select CHOICE data is stored as “;#ChoiceA;#ChoiceB;#...;#”
See the below code for adding listitem to Resource List.

Below screen shows the newly added Item in the edit mode

Page Hit Counter in SharePoint

You would have seen many sites displaying page hit counters. To display this in SharePoint page, insert the “Hit Counter” web component from SharePoint Designer.

Open your site or your sites Master page to insert this component. For the demonstration purpose, I’ve use my default.aspx to insert the “Hit Counter” component. Once the page is opened in SharePoint Designer, place the cursor where you want to insert the hit counter. Go to Insert --> Web Component.



Click on the Web Component, this will display the available web components. You can find different types of other components readily available.



Click on the Hit Counter component, this will display different counter styles. Select any one style from the list. I have selected the below marked style.



Click on “Finish”, this will open the below Hit Counter Properties window.



You can even create your own Hit Counter. Use “Reset counter to” to reset the counter from a given number. To display fixed number of digits use “Fixed number of digits” property. Click on “Ok”, the hit counter will be inserted to your page. The below code will be inserted in your page to display the counter.



Now, preview your page from SharePoint Designer / a Web browser. You can see the Hit Counter incremented for each hit.



You can see the Hit Counter increments for each hit.

Creating SharePoint List using Office Excel

I had a requirement to create SharePoint lists using Excel sheet data. Luckily I notice that there is an option in Office Excel to create SharePoint list using excel data. Below screen shows the “Employee” data. I have used Office Excel 2003 for publishing excel list to SharePoint.

To create a SharePoint list, select the excel data then go to Data --> List --> Create List. This will create a List in Excel. If you are using Office Excel 2007 then use this reference.

Select the created list in Excel sheet and go to Data --> List --> Publish List. This will brings up a popup for publishing the created list to a SharePoint site.

Use this popup to input information like “Address” of the site, provide list a name and Description.

Click on Next, This will brings up the column and associated data type information. To publish excel data to a SharePoint list, Excel force columns to use certain types.

Click Finish to publish list to SharePoint.

Now, open the published site and add the newly created “Employee” list to the page. Below screen shows the Employee List which is created from Office Excel.

This approach will help to create SharePoint list from Office Excel with minimal effort.

Displaying Pdf document in SharePoint Page

Pdf documents can be displayed in SharePoint site with the use of “Content Editor Web part”. To know more about "Content Editor Web part", I suggest you to read this post, where you will get to know about playing a video in SharePoint site.

Add a “Content Editor Web part” to your SharePoint page, Click on the “Open the Tool Pane”, click on “Source Editor” to place the HTML source.
Place the following piece of code in to the Source Editor



In the above code, “src” points to a source location, the location can be a HTTP or a UNC path. I’ve stored my Pdf document in my document library and used the Http location of my Pdf file. Also Set the Height and Width properties and click on “Ok”.





The above image shows the embedded Pdf document to a SharePoint page.

Calculated column to display month name from a date

I was haing a requirement to display the month name from the selected date like January, February etc. I have created a calculated column and used a formula to display the month name.

Create a custom SharePoint list and a date column, a calculated column to it and other columns to it. For the demonstration purpose, I have created a list “Employee List”, with “Emp ID”, “Employee Name”, “Joining Date”, and “Month Calculated” columns. Here “Month Calculated” is the Calculated Column.



Above image shows the column details of "Employee List".

In the Calculated Column, use the following formula to get the month name from the “Joining Date” column.


=TEXT([Joining Date],"MMMM") -- To Display “January”, “February”, etc
Or
=TEXT([Joining Date],"MMM") -- To Display “Jan”, “Feb”, etc






Above image shows the “Month Calculated” calculated column.


Once the columns added to the List, Add new items by clicking “New”.



After selecting the “Joining Date” Click ok. Now the calculated column will display the month name for the selected “Joining Date”.

Registering Assembly to GAC via Code

Registering Assembly to GAC via Code

As we know to register an assembly toGlobal Assembly Cache, the assembly must be strong named. This strong name is used to prevent spoofing of your code. Use the “gacutil.exe” to install the assembly to the GAC.

Example

gacutil /i MyAssembly.dll

The above command will installs the “MyAssembly.dll” in to the GAC.
See the following code snippet to do the above stuff by C# code.

try
{
string assemblyName = “MyAssembly.dll”;

ProcessStartInfo pStartInfo = new ProcessStartInfo();

//specify gacutil.exe whith which to start the process
pStartInfo.FileName = "gacutil.exe";
pStartInfo.Arguments = string.Format("/i {0}", assemblyName);
pStartInfo.UseShellExecute = false;

//start the process
Process process = Process.Start(pStartInfo);

//wait till the process completes
process.WaitForExit();
}
catch (Exception e)
{
MessageBox.Show(string.Format("Error registering the assembly :
'{0}'.\n{1}", assemblyName, e.Message),
"GAC Installation Error");
}

The “UseShellExecute” property indicates whether to use the operating system shell to start the process. The default is “true”. Set this property to “false” – The process is created directly from the executable file.
