Hi,
I have a EO.web.grid on page and added one TextBoxColumn to it, for some reason the TextBoxColumn is locked, not allow me to edit, even I set property ReadOnly = false and always return true in client ClientSideBeginEdit. I have no idea where's wrong in my code.
Can you help out for this?
Thanks in advance
William

Hi,
You have already mentioned the two things that should be checked. So we do not know what else to tell you to check. You can try to compare the non-working code with a working sample to find out what's wrong.
Thanks!

Hi,
Can you tell me how many max columns we can create in EO.Web.grid?
Thanks

Hi,
No. The Grid does not restrict number of columns. However the Grid is optimized for rows, not for columns, so using more columns will quickly degrade the performance ---- we don't have an exact number because it depends on a lot of factors such as the size of the Grid, how complex the contents in the cell is and how fast the computer on which it runs is. In any case, we do not recommend you to use a lot of columns.
Thanks!

Hi,
I found if I use a lot of columns like 140 columns, the first 40 columns will be locked and the rest are unlocked, and then I reduced columns to less one like 5 coulmns it is all fine, so far I tested those less than 100 columns are all fine!
Is there anything you could advise me?
Thanks
William

We are not aware of such issues. But you definitely want to reduce the number of columns. The Grid is not designed with that many columns in mind.
Thanks!
