Extjs 4.0.2a breaks grid column hiding?

I am facing same issue in my grid panel. As per my findings, this issue is arising when the number of columns increases.

I am facing same issue in my grid panel. As per my findings, this issue is arising when the number of columns increases. In my grid, I have 41 columns.

When all 41 columns were displayed in the Grid, then the column menu in header was falling at the top and not displaying the list. But when I reduced the number of columns to 23 then the list at column menu was appearing correctly and also at the right position. I guess it has something to do with the entries which the columns menu can accommodate given the height of display area in browser window.

But I am myself looking for some robust solution for this. ExtJS version used by me is 4.0.2a. OS-Win 7.

Browser-MZ 4.0.

My grid has 300+ columns... Thanks for mentioning it's related to the number of column. I was just wondering why my small apps (with small number of columns) work just fine. – Mohd Shakir Zakaria Aug 25 at 4:13 Glad that could share something useful.

Currently I am trying to have a work around for this issue. If succeeded then will post here. – NetEmp Sep 4 at 15:28.

This is a bug, fix is to do the following as explained at: sencha.com/forum/showthread.php?138927-4...)&p=620730&viewfull=1#post620730 I tested using Ext 4.0.2a version, and works.. In the Ext.menu.Menu. DoConstrain function... change: ... delete me. Height; me.setSize(); full = me.getHeight(); ... To: ... full = me.getHeight(); delete me.

Height; me.setSize(); ...

The menu constraining has been fixed since 4.0.2a. When the next public release comes out (very soon) the fix will be in there.

The bug menu from Ext JS 4.0.2a is fixed in the new available version Ext JS 4.0.7.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
