Can anyone explain the below code, which is from a gridview_rowdatabound method

Question

0.00/5 (No votes)

See more:

Dim tblIdTitleHdr = CType(e.Row.Parent, Table)

tblIdTitleHdr.Controls.AddAt(e.Row.RowIndex * 2 + 1, idTitleHdr)

What I have tried:

Here, idTitleHdr is a new GridViewRow.

Basically, what this Code does is to repeat a header for each row in a Gridview. The Code's working fine. I just want to know what the above lines of Code do actually. Any help would be greatly appreciated.

Thanks!

Solution 1

It's adding a control (idtitleHdr) to another control's "child control" collection (probably a "panel" type).

Only you know the context: what controls tblIdTitleHdr and idTitleHdr are; and what OTHER CONTROLS are in the collection that cause the "headers" to be inserted over a "range" (i.e .... * 2 + 1).

The order in which controls are added to a (parent) collection influences to order in which they are rendered.

Thanks for the response @Gerry Schmitz. Yeah, I think I understand what that Code does now. BTW, idTitleHdr is a new GridViewRow. Sorry for not mentioning that in the question. :)

@Gerry Schmitz. May I know what exactly is e.Row.Parent in this case?
