Hello,
I've been looking a simple way of obtain something similar to this http://www.extjs.com/deploy/dev/examples/grid/array-grid.html and get a column menu to select which columns to display and the column ordering.
Will Telerik WebGrid support this in the next future? is any way to implement it in a simple way with the actual webgrid control?
Thanks a lot for your answer!

Hi Kementeus,
One work arround will be to show the ContextMenu on clicking the ColumnHeader. Add one CheckBoxList in the ContextMenu and populate it with the column name. Hide the columns from client side on clicking the CheckBox.
Thanks

Does somebody knows if this feature would be available "in the box" in the near future? someplace where could I post it as a feature wishlist?

Hello kementeus,
We will definitely consider exposing context menu on a per-column basis for the upcoming version of RadGrid for ASP.NET AJAX. At this point you may consider implementing such functionality using RadContextMenu explicitly as demonstrated in the project from this code library thread:
http://www.telerik.com/community/code-library/submission/b311D-tkhat.aspx
I updated your Telerik points for the valuable feedback.

The Visibility of column made visible from client side is not displayed once there is a post back like column sorting.
Any suggestions on this would be appreciated.

Hi Siddharth,
Can you replicate the abnormality in the project from the code library thread I linked? I tried to reproduce the erroneous behavior but unfortunately to no avail. Also verify that you are using the latest release 2008.2.1001 of RadControls for ASP.NET AJAX in your project.

Hi,
Can you use the code below to replicate this scenario
Hi,
I was able to achieve point 2 and 3 and i am attaching sample for the same.
I am facing two problems in attached sample.
1. When a hidden column is made visible for first time then footer is not of correct size.
Steps to reproduce using Sample:
a. Run Application
b. Right Click on header and click Show Columns -> Subject.
c. Footer width is not 100%
2. When two columns are made visible and then sorted the columns dont get displayed.
Steps to reproduce using Sample:
a. Run Application
b. Right Click on header and click Show Columns -> Subject.
c. Right Click on Subject header and click hide Column
d. Right Click on Score header and click hide Column
e. Right Click on header and click Show Columns -> Subject.
f. Right Click on header and click Show Columns -> Score
g. try to sort on Subject column then only column which was not hidden previously is seen.
Can you please look into this issue ASAP.
