Fixed Column : Serious Issues

[Nabeel]

Hello Everyone,

Fixed Columns is the basic feature of our application. We need to have fixed columns and multiple merged headers and other complex functionality in your Grid. When we proceeded with your Grid, we encounter serious issues. Some of the documented issues on your site are as follows which clearly states that these are not supported.

Unsupported scenarios

There are several limitations that you should have in mind. They are caused by the complexity and specifics of the frozen columns feature, which is implemented by means of hiding and showing columns, instead of actually scrolling them.

• Resizing with frozen column is not supported.  (We don’t need that)
• Having hidden columns (with Display property set to false) or hiding/showing columns and frozen columns are not supported at the same time. Hidden columns reappear after scrolling.  (Problem)
• Merged headers with frozen columns are not supported. (Big problem for us)
• When frozen columns are used, tabbing between the textboxes in an inline edit form is not supported out-of-the-box, because the frozen columns will be scrolled together with the non-frozen. In selected scenarios, this functionality can be achieved if you subscribe to the textboxes' focus events and scroll a specific <div> with Javascript. This <div> has a client ID of "..._Frozen" where "..." is the RadGrid client ID. When doing this, you should take into account the current scroll position, and the width of the column that should be hidden/shown.
• OnScroll client-side event does not fire when horizontal scroll is used for scrolling. (not a problem for us)
• Frozen columns are not supported for detail tables of hierarchy grid. (we don’t need that)

Please let us know if there are any workarounds for each of the mentioned issues. We seriously need some solution about these issues, specially the ones which have comments in brackets next to it.  We want to know if these issues will be addressed in the next versions. These are Bottleneck for us to use in our application

Thanks and Regards

Hi Nabeel,

Unfortunately there is no way to workaround the problems with hidden columns and merged headers with frozen columns. Please excuse us for the inconvenience.

Regarding the problem with tabbing between the textboxes you can examine the link below:
