RegEx for URL validation

[Malcolm van Staden]

Hi,

I'd like to use the masked edit for basic URL validation but I'm unsure how to go about doing so with the limited mask characters that the SfMaskedEdit allows.

Could you please assist?

Thank you

Hi Malcolm, 

 

Greetings from Syncfusion. 

 

We have prepared a simple sample for the simple Regex mask. Please refer the below code snippet. 

 

<maskededit:SfMaskedEdit x:Name="maskedEdit" MaskType="RegEx" Mask="(https?:\/\/)?([\w\-]+\.{1}([a-zA-Z]{2,63})([\/\w-]*)*\/?\??([^\n\r]*)?([^\n\r]*)"/>

Output: 

 

 

We would like to let you know that the reported query it’s general query. Based on your requirement to validate the url, you can give Regex to set value for the Mask property. we have provided support for limited Mask. Please refer the following user guide link for more information about regular expression that supported by MaskedEdit.

Hi

I tried your regex and it shows invalid URL because of the dot

Please see the attached sample

Hi Jassim Rahma, 

We have checked your query and screenshot. We would like to inform you that, we must provide any letters or hyphens (-) before the dot as per the previous Mask, then only it is the valid Url. Otherwise, it is invalid. In your screenshot, you didn’t provide any letters or hyphens before the dot. So only it returns as invalid. Please refer to the screenshot below 

 

(https?:\/\/)?([\w\-]+\.{1}([a-zA-Z]{2,63})([\/\w-]*)*\/?\??([^\r]*)?([^\r]*) 

The [\w\-]+ denotes, you must type any number of letters or hyphens. 

Also, as we have mentioned in our previous update, the regular expression is a general concept of C#, and our MaskedEdit supports it to specify the rules for accepting inputs. So, you have to create a regular expression based on your requirement. 

Please find the below guidelines for generating the regular expression mask
