Datagrid and Expanded Click to Child ( + and - rows)

[gollnick]

I have a merged datagrid with parent/child relationship. When I double click on the Master (parent) row all is good. When I expand a row to look at the children and double click one of THOSE rows I am not getting the proper row number and data returned (keys and such to get the child record).
How do I determine which row and which table from dataset to look in?

Thanks

What exactly do you mean by "row number"? What exactly are you doing, what exactly are you expecting to get and what exactly are you getting?

[gollnick]

Example -- I have a list on the grid of Apartment Houses by Unit -- this is the parent line
The Child (what you see when you press the + symbol) IS THE 10 OR SO units in that apartment house and who the tenant is.

If I want further information on A tenant in AN apartment I want to double click that child row. What I am returning is actually the ROW of a PARENT level

Say I have 5 Parent rows of different apartment buildings.

I open the 3rd row at the upper level showing me now 12 detail rows rows associated with that parent. Say that this detail row 5 is the child I want more info on. I double click that row BUT I am returned on the doubleclick event that row and data for the FIFTH (5) Parent row -- not the fifth row child of the third parent row

Got it??

thanks

It would help if we could see the code. Clearly you are using the wrong code but if we can't see the code then we can't see what's wrong with it.

I think from what I understand of the question you will need to use a custom datagridview either one from devexpress which already does what you will require or code one yourself.

However as JC points out its difficult to undrstand what you are trying to achieve without an example in any form.

I've already come to the conclusion of Leary222. I'd include the code snippets but have any of you used ASNA and Visual RPG vs vb.net or c#.net?? Different syntax but accomplishes all that the other two .net languages provide.

I think you're wrong but I'm trying to help when you refuse to post your code.

/endRegion Get records for datagrid



Here is the code that loads the datagrid

dsDocuments = TENANTS.Getit_For_Datagrid_TENANTS_Merge("a" , optOrderAscend.Checked , *ByRef ParmYesNo)
dgGrid1.SetDataBinding(dsDocuments , "Upper")



Then this
Example -- I have a list on the grid of Apartment Houses by Unit -- this is the parent line
The Child (what you see when you press the + symbol) IS THE 10 OR SO units in that apartment house and who the tenant is.

If I want further information on A tenant in AN apartment I want to double click that child row. What I am returning is actually the ROW of a PARENT level

Say I have 5 Parent rows of different apartment buildings.

I open the 3rd row at the upper level showing me now 12 detail rows rows associated with that parent. Say that this detail row 5 is the child I want more info on. I double click that row BUT I am returned on the doubleclick event that row and data for the FIFTH (5) Parent row -- not the fifth row child of the third parent row
