Dear experts,
each time I collect data from database, I have more than 500 records and each data need to be digested before I populate in customised datagridview. By using "For Each" looping, it took 10 - 15 seconds, so I decided to use datasource to add the data into datagridview.

But how can I make some of the existing columns become DataGridViewButtonColumn if I am using datasource to add data into datagridview?

Solution 1

Manually define you column at runtime.

VB

Datagridview1.DataSource = MyDatatable

With Datagridview1
 .Clear
 .AutoGenerateColumns = False

'Textbox Column
 .Columns.Add("ColumnName1", "Column Name 1")
 .Columns(0).DataPropertyName = "FileName"'Datatable column Name
 .Columns(0).DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft

'Checkbox column
 Dim m_Active As New DataGridViewCheckBoxColumn
 m_Active.HeaderText = "Active"
 m_Active.DataPropertyName = "Active"
 .Columns.Add(m_Active)
 .Columns(1).DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft

'Button Column
Dim m_ButtonColumn As New DataGridViewButtonColumn
m_ButtonColumn.HeaderText = "SomeValue"
m_ButtonColumn.DataPropertyName = "SomeValue"
.Columns.Add(m_ButtonColumn)

End With

Winston Madiano,
For the Button Column, is this method adding a new column or changing the existing column to button column?

Since we set AutoGenerateColumns = False the Datagridview1 has no columns, we have to manually add them and set the properties on how we want to display the data.
This will add a column with header text(SomeValue) and the cell values would be buttons.

I have customized the datagridview with textboxcolumn and buttoncolumn.... but when I apply the datatable to the datasource... I got blank record

dgvList.AutoGenerateColumns= False
dgvList.Datasource = ds.Tables(0)

make sure that the DataPropertyName has the same column name on your datatable column.
