This is probably the same or similar issue to http://forums.infragistics.com/forums/t/69401.aspx
And is also somewhat related to an earlier post I made here http://forums.infragistics.com/forums/t/69426.aspx
So since the grid is taking 2-5 seconds to load the data and since I have a hidden column, the column header that is hidden is appear as undefined until the data is loaded.
Hello Exceed,
I tried to reproduce the issue using the sample attached by Christoff:
http://community.infragistics.com/cfs-file.ashx/__key/CommunityServer.Discussions.Components.Files/499/6165.InfragisticsGridHiddenColumns.zip
The only change that have to be tone is to remove the option
autoGenerateColumns: false,
After this change the sample works as expected.
Hope this helps.
I already have the grid set to false, my sample code for the grid is here: http://forums.infragistics.com/forums/t/69426.aspx posted as slinex replied on Wed, May 23 2012 5:36 PM and Borislav Traikov posted a sample that is similar to mine.
Hi Exceed,I believe I've made my MVC project from that thread (http://forums.infragistics.com/forums/t/69426.aspx) a pretty good replica based on the code that slinex provided.From what I understand, your project actually has more code (a bigger configuration of the igGrid) that slinex mention, am I right?If so, can you let me know what your exact configuration of the grid looks like?If my sample project is indeed good enough, can you please let me know if you can reproduce the problem with the 'undefined' header text of a hidden column in it?Basically, what I'm trying to say is that I haven't seen a development issue like the one you describe so far so I would like to know how the grid is configured - something very tiny may be causing development issue or there could just be a slight mis-configuration.Finally, if possible let us know what volume release (2012.1 for example) are you using and which version (for example build #1023 is the RTM version for 2011.2 while build #2119 is the latest Service Release).Thanks in advance!Will be looking forward to demystifying this scenario.
Hi Borislav,
Your example is pretty much accurate except for a few extra columns we're displaying and that CallID should be set to to true instead of column.For(x => x.CallID).Hidden(false);
What happens is the grid is rendered with the hidden column but once the rows are rendered, the hidden column disappears. And since I didn't give it a HeaderText it shows as a undefined column header.
We are using the latest release jQuery 2012.1 so I believe we have the latest build #2119.
Hi Exceed,Thanks for pointing out that I had set hidden to FALSE for that column. You are correct about the issue - the hidden column is indeed shown with the 'undefined' header text while the grid waits for the 1st 50 records to come.This seems like a development issue, but also one that's very tightly-packed with the way the grid renders column headers when at least one is hidden.I can submit the issue to the RnD team if you wish.However, I can offer you a workaround that should fit right into your scenario - set 0 pixels width to the CallID column and still set hidden to TRUE. It might seem a bit weird, but it gets the job done.Please give this suggestion a go an let me know what's the outcome.Cheers!BorislavPS: Initially I wasn't able to see the problem because my browsers had cached the page data and the server where I host the project had also cached some data so everything was going lightning-fast (even under IE). It was only after a restart of the server and a purge of the browser cache that I was able to see the issue - this is a more of a note to anyone who's looking at this forum thread and has trouble reproducing the scenario.
The workaround indeed works and yes it does seem weird to have to apply it to all the grids.
If you can submit this issue as a bug that would be great.
Thanks.
Hi,Sure thing - I've logged internal bug with ID 113972 about this to our RnD team.PS: Just a suggestion: you can place an empty string for the Header Text of such hidden columns - that way you won't get that nasty "undedfined"
Thank you.
Actually I have tried putting a empty string "" as the header text but then I get a nasty null showing up, I would have to put " " in order for it to show up as a blank.
