Dear all,

is there any chance to reindex my DataGrid without exporting/importing the Datas?

I ask because after I fill this DataGrid I am using
to sort the information with the item mobile_sortieren. Then I am able to click on a entry in my DataGrid and open the informations in another card. From there I want to "Swipe" forward / backward. But my problem is that the Index is now sorted (e.g. 5,2,4,3,1) and I have no Idea how to access the information for e.g. before/afterwards index 4 because I can not work with 4-1 or 4+1.

Q1: How can I reindex the DataGrid after the sorting
Q2: How can I read out the keys from the Index of a DataGrid (e.g. 5,2,4,3,1) , is there any command?

Thanks
Stefan

Hi.

Q1: How can I reindex the DataGrid after the sorting

I never do. I massage everything in either the dgText or the dgData and reload. Much more comfortable for me than to fool around with the data grid API.

Q2: How can I read out the keys from the Index of a DataGrid (e.g. 5,2,4,3,1) , is there any command?

The dgData is an array containing the entire contents of the DG. You can work directly in there, no?

Hi Stefan,

can't you use LINE instead of INDEX?
With "dghiliteslines", "dgIndexOfLine", "dgDataOfLine", "the dgline of grp xyz" etc.?
