View 17 RepliesI have a Datagrid with 5 columns, one of those columns is the only one to have fixed values.Let's put this in a simple way, that column (lets name it column A) contains rows with values from one to ten.With an API call I get some information, lets say I got this:
1 - Andrew - 1.8
8 - Peter - 2.8
Something like this.The first number is equal to the value on the column A, the other two are name and height. I will note receive all the values (one to ten) with call or full information relating to all the columns.How can I assign the information I receive to the proper row based on one of the value I get with the call? Another thing, I will have to create a lot of rows, do I need to add them row by row?
