Hiding Columns in Grid.

Hi,

We are trying to hide columns (of type NumberField and TextField). The columns can also contain null. But there is a problem while rendering the grid. We are getting "'undefined' is null or not an object" error message.

 

Also we have three grids on the screen. We get this error only when we are trying to load the page and there is no data in the grid.

 

the error "'undefined' is null or not an object" is coming on the page "GridFxResource.axd". Following is the code where it shows error :

It gets the value of $6 as null. Also, the value of $5 = 1 and $4=0.

 

Initially we had kept fixed height and width of the grid. Now we have removed that too. But still we are facing the same problem. Please let us know if we need to change any setting.

 

Thanks for your help.

Have you updated to the latest service pack?  In the latest update we did lots of empty data fixes, which is what this looks like.  You can update through "Check for Updates" in the grid's smart tag wizard in visual studio or at http://support.softwarefx.com/ShowInteractive.aspx?Product=GridFX10&option=0.  Let me know if you still experience the problem with the latest version.
