'Okey before doing this create two column namely colCusName and colCusNameID.


Public rsName As New DataTable
 
If rsName.Rows.Count > 0 Then
 
            Me.Cursor = Cursors.AppStarting
            Dim custRows() As DataRow = rsName.Select("CusName like  '%" & (TextBox38.Text) & "%'")
 
            Datagridview1.rows.clear
 
            For Each row As DataRow In custRows
            
            Dim rowIndex as integer = Datagridview1.rows.add
            
            Datagridview1(me.colCusName.index,rowindex).value = row.Item("CusName").ToString().Trim()
            Datagridview1(me.colCusNameID.index,rowindex).value = row.Item("CusNameID").ToString().Trim()
               
            Next
 
            custRows = Nothing
            Me.Cursor = Cursors.Default
 End If

Hi JackOfPH,

i already create two column namely colCusName and colCusNameID.
I have error in below line

 Dim rowIndex as integer = Datagridview1.rows.add
below is the error
Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound.


I have error in below line too.
me.colCusName.index
me.colCusNameID.index

it say
'index' is not a member of 'String'
"colCusNameID" is not a member of "windowsApplication1.form1"

Your grid is bounded...

Please remove this...

Datagridview1.Datasource = rsNAme

Did you have any variable named colCusName , colCusNameID aside from the name columnname?

For example did you declare something like this?

Dim colCusName as string or colCusNameID?


If so please change it to other name...


Also, If you can post your code here, please do, so I can check it out...

Try this,
rsName.DefaultView.RowFilter = "CustName Like '%" & TextBox38.Text & "%'"
DataGridView1.DataSource = rsName.DefaultView
