Hi,

I am new with JS. I have an ASP.Net web app that uses JS to check and uncheck checkboxes inside a gridview. The gridview is in a separate page, and the JS function is in a separate file. The JS function has a code

TotalChkBx = parseInt('<%= this.grdIndustry.Rows.Count %>');

...i get an error in this line, and in other lines that has a

this

function. What should i put to replace the this functions?

Thanks,

Franco

The gridview is in a separate page, and the JS function is in a separate file
If so, then the below code would not work.

HTML

TotalChkBx = parseInt('<%= this.grdIndustry.Rows.Count %>');

In order to use the server delimiter <%= %>, you need to be on the same page.

so how do i count the number of rows in the gridview from a separate JS file?

One possible way: pass the gridview id to the Javascript function. Find the gridview in JS using getElementById and then it's row count.
