Thanks Ramakrishnappa n sharath,
As per ur ur above post am getting the user clicked cell value in r_param->value(here the user performing link_to_url action on sanction order no(kblp-kblnr))...I need to concatenate this r_param->value with one string like "Sanction order no.is....".
Here the problem is iam unable to convert the r_param->value to char.If i can able to convert it to char.then i caoncatenate this r_param->value to "Sanction oreder no.is..."
Please suggest me it is urgent...thanks in advance.
