Hi Experts.
I'm using Data GridView in VB.net. I add the rows dynamically by using Rows.Add() .
and after adding the row i set the value of last row in the gridView. this works fine for first time but when i add the second row , data from the first row got deleted. How this possible?
At which index Rows.Add() will add the row. if it add the row at last then my program should work fine.

Here is the example of my code (please don't look at syntax error as i have not Studio right now)

datagridview.rows.add()
datagridview.rows(datagridview.rowcount-1).cells(0).value = Somevalue

this will update the only last row every time and previously added row's data got cleared.

Please help

Hi Agnihotri,

I can reproduce the issue on my side. datagridview.rows(datagridview.rowcount-1 ).cells(0).value is the last row (NewRow with star at the row header). You should use
datagridview.rows(datagridview.rowcount-2 ).cells(0).value. That is the actually last row.

Hope you can solve the problem. If you have any question, please feel free to tell me.

Sincerely,
Kira Qian

That is because Row Addition Operation wasnt completed for row at the index RowCount-1

use

DataGridView1.Rows.Add((i + 1).ToString, Nothing,...nothing for all columns) instead of setting single Cell.
