hello, I have retrieved a cell value(eg. CustName Peter) from gridview(eg. grdView). Then I want to compare it with the rest of the records in gridview(using loop). How can I do it. Any help would be appreciated.

Solution 1

Use a foreach loop
ex: (in VB.Net)

VB

Dim name As String = "CustName"
Dim columnIndex As Integer = 1
'this is the column index which contains the value to compare

For Each dr As DataGridViewRow In DataGridView1.Rows
    If name = dr.Cells.Item(columnIndex).Value Then
        'do anything
    End If
Next dr

Hope this helps..
Regards

0 is the first column, 1 is the second column and so on.

after I have typed the grdView.Rows, it prompt me the Rows is not a member of Datagrid, what is meant by that?

Check the Updated one, use "dr.Cells.Item(columnIndex).Value" and "dr As DataGridViewRow"
I have tested it.

dr.Cells.Item(columnIndex).Value, the system says that Value is not a member of TableCell so i replace it with Text but it cannot get the value.
