How to store and retrieve a Signature content in SQL database?


The Signature control by default records the drawn signature in Base64 string format for later regeneration. Hence we can use this to store and retrieve the signature in SQL database.


To store the drawn signature image in the SQL database follow the steps below:

  1. Define a Signature control and buttons for Save and Restore the signatures from database.
  2. On client side click handler, get the signature content and convert it to the Base64 string value by using the canvas toDataURL() function and then pass it the code behind by using jQuery AJAX or AJAX ScriptManager pagemethods.


  1. Now, establish a connection to the database SQL and then need to store it in the database table.
  2. The same way is required to retrieve the stored canvas string from the database.
