当前页面的AspxGridView更改数据表列值

Question

Problem : DataTable (50K+ Rows) is binded with Aspxgridview, now we want to change DataRow column Values... for example instead of UserId display UserName. I can enumerate 50K rows and update userid with username at runtime but i want to enumerate AspxGridView current page DataRows and update their values only.

Can anyone guide me ? which event to use to update dataRow values of current page only for Aspxgridview ?

Answer 1

You should NOT iterate through the 50K records an update the UserId with the UserName.

One, you probably cant because UserId sounds like a numeric field (or at least it should be) and UserName is a string field. You can't put a string in a number.

Two, You should change the way you get your data, likely from a database, to JOIN the table you have here to the table that has the user names, and bring in the data you want. This way, it is done, and done fast.
