web forms and signature control

Thread ID:

Asked On January 5, 2017 08:44 PM UTC


Firstly, I would like to thank you for the controls you have created.  Some of the best ones I've come across.

I'm currently attempting to implement your signature control on an ASP.net Web Forms applications. 

The form has a few fields that are filled out, verified with the use of JavaScript and then passed back to the server side.

On the client side click event, I can easily verify if  a signature is there, however when I go to the back end I cant access the image, or at least, I don't know how.

I tried checking for documentation/forum posts, but none are available.

More or less, what I want to do is take the signature, convert it to a byte[] and store it in a sql database where it can later be retrieved and viewed.

Any help and directions will be greatly appreciated.

Forgot to mention that I am using c# in the back end.

Hi Donald,   
Thanks for contacting Syncfusion Support.   
Query1:” what I want to do is take the signature, convert it to a byte[] and store it in a sql database where it can later be retrieved and viewed”   
We have provided a sample by sending the canvas Base64 string value to the SQL database and save it in a table and retrieve the same value from it. Please find the attached sample below.   
Query2:” I tried checking for documentation/forum posts, but none are available”   
We are sorry for the inconvenience. Currently, we are working on the documentation and it be will refreshed in online soon. 
 If the shared sample doesn’t fulfill your requirement, please share us with additional details. It would be helpful to provide an alternate solution.

Hi Arun,

Thank you for taking time to create this solution!

It works great!  I started down this road last night but didn't realize I was going in the right direction and i ultimately turned around and gave up.
