DataGrid Column Width

[Zoot]

Hi,

I am newbie with regards to VB so please be gentle....

I am reading in a text file that I split into four fields using string slicing. I am creating a DataTable in code, and populating it with the data from the text file, and then creating a DataSet in code and adding the DataTable to the DataSet, and then binding these to a DataGrid that I have placed on my form at design time.

It all works wonderfully well, and is as fast as I could ever have wished for. However, I would like to be able to control the individual column widths in the DataGrid, and I can't see a way to do it as the "Preferred Width" Property applies to every column. My fields are something like this:

DAY.........DATE............TIME...........EVENT
Wed........01.07.2004.....10.04.09......The Blackbird Flies South

So I would like to be able to individually control the column widths.

Thanks.

This is what I have used.

ds is my dataset.

colDescription is a previously declared column that is present in the dataset.

'Set the column styles
        Dim t As DataTable
        For Each t In ds.Tables
            Dim myGridTableStyle As DataGridTableStyle = New _
                                                        DataGridTableStyle()
 
            Dim col As DataColumn
            For Each col In ds.Tables("CalcTable").Columns
 
                Dim c As New DataGridTextBoxColumn()
                c.NullText = ""
                c.HeaderText = col.Caption
                c.MappingName = col.ColumnName
 
                If col Is colDescription Then
                    c.Width = 150
                Else
                    c.Width = 75
                End If
 
                myGridTableStyle.GridColumnStyles.Add(c)
            Next
 
            myGridTableStyle.MappingName = t.TableName
            DataGrid1.TableStyles.Add(myGridTableStyle)
        Next t

You sir are, indeed, THE man!

That did the trick. Many thanks.

Further to this issue......

I have my DataTable, and have added the DataTable to the DataSet, and then bound these to a DataGrid that I have placed on my form at design time. Following the excellent help, I have also been able to change the column widths as required.

Now, I have an array (0 to maximum number of rows in the data grid) that contains a color entry that I want to be able to apply to each line (row) on the data grid. Ideally, I would like to be able to change the foreground and background colour of each row in the data grid based on the stored entry in the colour array.

Is this possible? I will eventually want to be able to use searches to filter the data that is displayed, and the colours will need to be consistent.

Many thanks.

Scroll down to the bottom and see if the example is what you are after. I haven't read through the whole thing myself, but it looks like what you are asking for.
