Dear friends,

I have the following code block in my program-

dim RowPostion as integer 
If dt.Rows.Count > 0 Then
  MsgBox(dt.Rows(RowPostion)(0).ToString) 
  MsgBox(dt.Rows(RowPostion )(1).ToString) 
  dt.Rows.RemoveAt(RowPostion) 
End If

Problem is, i am able to read values, but fail to delete. It returns "There is no row at position(..)" while trying to remove the row.

I cound not find any solution.
Would you please help me regarding this issue?

SKPaul.

How can you see it "fails"? Did you run it under debugger? Are you sure this fragment of code is executed only once? Why you call it only if there is only 1 row?

Dear SAKryukov,
Thank you for your reply. Well, rewrite it-

dim RowPostion as integer
If dt.Rows.Count > 0 Then
MsgBox(dt.Rows(RowPostion)(0).ToString)
MsgBox(dt.Rows(RowPostion )(1).ToString)
dt.Rows.RemoveAt(RowPostion)
End If

Problem is, i am able to read values, but fail to delete. It returns "There is no row at position(..)" while trying to remove the row.

I hope the problem is because you didn't specified a starting value for the row position

try this

VB

Dim RowPosition as integer = 0
If dt.Rows.Count > 0 Then
  MsgBox(dt.Rows(RowPostion)(0).ToString)
  MsgBox(dt.Rows(RowPostion )(1).ToString)
  dt.Rows.RemoveAt(RowPostion)
End If

(First check the value of data row count and Row position then try to set the value of Row position one step back to its original position, if the RowPosition is starting with 1)
