Web Forms :: Capture Signature Using HTML5 Canvas And Save To Database As Image
Oct 21, 2015
I need to capture and save user signature to database on asp.net webform.
I found this plug-in: [URL]
I downloaded the example project and it is very simple, it has only fews file but I could not understand.
demo here: [URL]
How do I use this on a web-form page, let say on "save" button click postback event, it will save the imageurl of the signature under this format:
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAApIAAAE+CAYAAAA+
vvBuAAAgAElEQVR4Xu3de6w1XV0f8K8WvIEiFTAKXhBrab0AxUraaFET0xYxSGrrpSb
UahsjbcUoXhKtIiaaSFSSojHRUP7w0rQGKbZJ00ahN.........
to a string variable so I can save this string to database?
Also how do I use 2 signature fileds in a same page, because I want to capture signature of 2 users.

On my aspx page I am trying to capture user input and then tried to save them in database and also trying to post them onto another page. Now I am using the following code on the button click event:ASPX CODE:
<asp:Button runat="server" ID="cmdPress" Text="Save"
ValidationGroup="ValidateId" Height="26px" onclick="cmdSave_Click"/>
CODE BEHIND:
SaveCustomer();
SaveRequest();
cmdPress.Attributes.Add("onClick", "update(" + ID.Text + ");");
Now when I click save button then it the page waits and then I have to click again to close the page automaticallly and move to the next page. Can anyone tell me why I will have to click Save button twice to activate the button.
