Hi Abu,
I have issue with frozen column.
What is different from the example is that, i used column format in it .
A part of code snippet , upto which frozen option is used is:
$col = array();
$col["title"] = "trnid";
$col["name"] = "trnid";
$col["frozen"] = true;
$col["width"] = "10";
$col["sortable"] = true;
$col["search"] = true;
$col["editable"] = false;
$col["hidden"] = true;
$cols[] = $col;
$col = array();
$col["title"] = "istaskshifted";
$col["name"] = "istaskshifted";
$col["editable"] = false;
$col["hidden"] = true;
$col["frozen"] = true;
$col["editrules"] = array("required"=>true, "readonly"=>true, "readonly-when"=>array("==","1"));
$cols[] = $col;
$col = array();
$col["title"] = "year";
$col["name"] = "myear";
$col["width"] = "10";
$col["sortable"] = true;
$col["search"] = true;
$col["frozen"] = true;
$col["editable"] = false;
$col["hidden"] = true;
$cols[] = $col;
$col = array();
$col["title"] = "Week";
$col["name"] = "weekno";
$col["width"] = "70";
$col["sortable"] = false;
$col["search"] = true;
$col["editable"] = false;
$col["frozen"] = true;
$col["hidden"] = true;
$cols[] = $col;
$col = array();
$col["title"] = "dept";
$col["name"] = "deptcode";
$col["width"] = "70";
$col["sortable"] = false;
$col["search"] = true;
$col["frozen"] = true;
$col["editable"] = false;
$col["hidden"] = true;
$cols[] = $col;
$col = array();
$col["title"] = "Task";
$col["name"] = "taskdescription";
$col["width"] = "350";
$col["frozen"] = true;
$col["edittype"]="textarea";
$col["sortable"] = true;
$col["search"] = false;
$col["editable"] = true;
$col["show"] = array("edit"=>true);
$col["editrules"] = array("required"=>true);
$cols[] = $col;
