NullReferenceException while opening CRM form

September 19, 2012 Leave a comment

I was getting an exception when I open a “Account” record.

When I verify the CRM server Event Viewer I got this below “NullReferenceException” warning message



After spending some time I came to know that the problem was because of customization change I did recently


  • I deleted and recreated a custom field with same schema name but with different data type
  • I had the new field added on my ‘Account’ form


I can’t say that it is a fix but below step worked for me

  • Removed the field from the Form
  • Publish the customization
  • Add the field back to the Form

Here is a useful article which helped me



Set field values using query string parameters on Form load in CRM

October 11, 2011 Leave a comment


I have got below requirement,

  •  I need to open a CRM form from my custom ‘.aspx’ page.
  • On opening of the form I should populate “name” field with value

After referring MSDN article, I came to know that we can set the field values using “extraqs” query string parameter and it must meet below requirements.

  • You must encode the parameters passed in the extraqs parameter. Use encodeURIComponent to encode the parameters.
  • The names of the query string arguments must match or include the names of attributes for the entity.
  • The value cannot be a script (To prevent script injection)

Below is the sample JScript to open a form and populate “name” field on form load

function openform() {
var encodedString = encodeURIComponent(“new_name=rajeev pentyala”);“http://ServerName/OrgName/main.aspx?etc=10014&extraqs=” + encodedString + “&pagetype=entityrecord”);

  • Here “new_name” is the name of attribute

You get the CRM form as below, when you call the above function

extraqs query parameter

Please refer below useful MSDN articles

Hope it helps 🙂
