[woutercop]

I have made a grid Master / Detail
In master i have a checkbox (chkDelete) andin Detail i have a checkbox (chk2Delte, chkVisible)

if i click the submit button i want the checked values to be deleted or set on visible true/false
how can i get the value of the ID, and know if the item is checked yes or no?

here is frontend code

after some try and error ...
here is the solution

 

For Each i As GridDataItem In rdgCategories.MasterTableView.Items

 

 

 

If CType(i.FindControl("chkDelete"), CheckBox).Checked() Then

 

myAdmin.DeleteLeadAffiliate(

CInt(CType(i.FindControl("lblID"), Label).Text()))

 

 

 

End If

 

 

Dim gtv As GridTableView = TryCast(i.ChildItem.NestedTableViews(0), GridTableView)

 

 

 

For Each gdi2 As GridDataItem In gtv.Items

 

 

 

If CType(gdi2.FindControl("chk2Delete"), CheckBox).Checked() Then

 

myAdmin.DeleteLeadAffiliateCampagne(

CInt(CType(gdi2.FindControl("lblID2"), Label).Text()))

 

 

 

'Response.Write(CInt(CType(gdi2.FindControl("lblID2"), Label).Text()))

 

 

End If

 

 

If CType(gdi2.FindControl("chkVisible"), CheckBox).Checked() Then

 

myAdmin.UpdateLeadAffiliateCampagneVisible(

CInt(CType(gdi2.FindControl("lblID2"), Label).Text()), True)

 

 

 

Else

 

myAdmin.UpdateLeadAffiliateCampagneVisible(

CInt(CType(gdi2.FindControl("lblID2"), Label).Text()), False)

 

 

 

End If

 

 

Next
