Hi all,

I am trying to put validation on a textbox it is associated with a checkbox when user checked checkbox then validation should work otherwise not. And this is also related to a validationgroup in asp.net. If I click on the button then it must be checked and one more thing is that i can't put my js code in .aspx file it must be in separate .js file so please tell how can put wright one validation not to waste time in experimenting and it must be at client side.

Thanks!

Hi sat_dev ,

you can use JavaScript for your Validation in a separate file itself , Write a JavaScript in a file and store it as like 'FileName.js' and then include the Javascript file in the header of your .aspx file as mentioned below ,

Hi,

just try this

JavaScript

   function f1()
{
    if(document.getElementbyID("rdb").checked)
{
     //call validation method which is placed in another js file
}
else
{

}
}

All the Best
