Question

Using VB.Net

I want to make a datagird cell value zero instead of null

For example

Datagridview1

Id value1 value2 value3

01 null null 0
02 0 null 10
03 100 null 100
...

Expected output

Id value1 value2 value3

01 0 0 0
02 0 0 10
03 100 0 100
...

I have more than 80 columns and 100 rows, instead of checking the cell one by one any other method is available

Tried Code

    Private Sub dataGridView1_CellFormatting(sender As Object, e As DataGridViewCellFormattingEventArgs)
        If e.ColumnIndex = 0 AndAlso e.Value IsNot Nothing Then
            If CInt(e.Value) = 0 Then
                e.Value = ""
            End If
        End If
    End Sub

The above code is not working properly, when i add the details in datagridview from database, showing null cell also.

How to make zero instead of null. Any other method or suggestion

Need VB.Net code help

Answer 1

• Right-Click the DatagridView and click on Properties.
• In the Property window, locate DefaultCellStyle
• Click on the Tab
• In the Dialog that appear, specify the NullValue

You can also set it from code

dataGridView1.DefaultCellStyle.NullValue = 0;

Gets or sets the System.Windows.Forms.DataGridView cell display value corresponding
to a cell value of System.DBNull.Value or null.
