Using a datagrid to show dataset. I'd like to add a column to my table. I've looked into the code already present, and the only way i've found so far was to play into the Windows Form Designer generated code


Any better idea ? some quick editing tips to add a column. Coze adding it this way can be long.

Dim dsDataset As New DataSet

dsDataset.Tables(0).Columns.Add("NewColumn")
dsDataset.Tables(0).Columns("NewColumn").DataType = GetType(Integer)
dsDataset.Tables(0).Columns("NewColumn").ColumnName = "MyNewColumn"

For a checkbox, you simply need to change the Datatype of the column.  A checkbox can have values of True/False, which is a Boolean, so:

 dsDataset.Tables(0).Columns("NewColumn").DataType = GetType(Boolean)

Here how is it working:

I have a column named "Resp" using :
    Friend WithEvents dsHistoricRespCol As System.Data.DataColumn
and
    Friend WithEvents dgtbHistoricRespColStyle As System.Windows.Forms.DataGridTextBoxColumn

When I do resizing or similaire stuff, i do the modifications on the datagridtextboxcolumn.


So far i have added the column via the .NET interface and it creates a datacolumn. But how do I set a style via the interface ?


        Me.dgtbMeasLimitMaxColStyle.Format = ""
        Me.dgtbMeasLimitMaxColStyle.FormatInfo = Nothing
        Me.dgtbMeasLimitMaxColStyle.HeaderText = resources.GetString("dgtbMeasLimitMaxColStyle.HeaderText")
        Me.dgtbMeasLimitMaxColStyle.MappingName = resources.GetString("dgtbMeasLimitMaxColStyle.MappingName")
        Me.dgtbMeasLimitMaxColStyle.NullText = resources.GetString("dgtbMeasLimitMaxColStyle.NullText")
        Me.dgtbMeasLimitMaxColStyle.Width = CType(resources.GetObject("dgtbMeasLimitMaxColStyle.Width"), Integer)
 

Knowing the defenition of the style column, it is using the resources files, so it gotta be created via some "tools". I dont think its efficient to edit all this stuff manually.

Through the interface, you can define a DataGridBoolColumn by pulling down the drop-down list:
