workaround to the issue with the DataSheet View (if you have custom master page)
On creating a new ‘Datasheet View’ in a simple OOB Custom List or Document Library (where System master page is a custom master page) leads to either a hang (IE8) or an infinite loop (IE7)
Leading to ever growing of window height both resulting in a CPU crash.
During the script debugging found that the following are the two functions in Core.js which are going to infinite loop when custom master page with footer is present for the system pages.
GCWindowResize and GCOnResizeGridControl
The workaround is to add counters in these two functions to overcome the infinite loop. The new functions would be as follows.
var win_resize_counter = 0;
var obj_resize_counter = 0;
function GCWindowResize(GCObject) {
win_resize_counter++;
if (win_resize_counter < 3) {
if (TestGCObject(GCObject)) {
glGCResizeCounter = 0;
GCResizeGridControl(GCObject);
}
}
else
win_resize_counter = 0;
}
function GCOnResizeGridControl(GCObject) {
obj_resize_counter++;
if (obj_resize_counter < 2) {
if (TestGCObject(GCObject)) {
if (glGCResizeCounter < cGCMaxGCResizeCount) {
glGCResizeCounter++;
GCResizeGridControl(GCObject);
}
}
}
else
obj_resize_counter = 0;
}
