Use the debugger to see what the actual value of ((LinkButton)sender).CommandArgument is. It probably isn't what you expect.

As I said, "use the debugger".

Whatever is returned by ((LinkButton)sender).CommandArgument can't be converted to Int16. Use the TryParse function instead of Parse so you can handle when the text can't be converted.

where i am using TryParse function

F-ES Sitecore 15-Feb-16 11:24am

Instead of Convert.ToInt16 use Int16.TryParse instead.

Read the MSDN documentation!

Boopalslm 16-Feb-16 2:13am

pnlProducts.Visible = true;

int CategoryID = Int16.TryParse((((LinkButton)sender).CommandArgument));
GetProducts(CategoryID);

Now i am use as per your ideas, but same line is error is came, please give me ideas.

F-ES Sitecore 16-Feb-16 4:30am

int CategoryID = 0;

if (!Int16.TryParse((((LinkButton)sender).CommandArgument), out CategoryID))
{
// do something to handle when parse fails
}
GetProducts(CategoryID);

Obviously, Boopalslm, you didn't respond to the proper comment... And you didn't read the documentation.
