detect a datagridviewtextboxcolumn resize 1

[Keyth]

Hi All.

I am struggling to find a way of detecting when a datagridviewtextboxcolumn has been resized. The columns are constructed at run time and added to the datagridview. I want to be able to detect when a user has resized a column and then when the form reloads set the columns width to the previously stored value.

Any ideas??

Thanks,

Keyth.

Hi,

you could use application settings to store each column's width.
Load the values when the form load. Save the values when the form closes.

This article can help you on using application settings:

Hope it helps

The problem I have is not with assigning the column width or saving it.

I would like to detect the resize of a column so I can then store the new column width value.

Ok,

then you could handle the ColumnWidthChanged event of you datagridview.

Hi again.

I have tried this and that event fires when the datagridview is being created or painted, not when the user is resizing the column.

Thanks,

Hi,

I've just tried it and it works:

    Private Sub DataGridView1_ColumnWidthChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewColumnEventArgs) Handles [b]DataGridView1.ColumnWidthChanged[/b]
        MsgBox("columnwidthchanged")
    End Sub

Are you sure you didn't handle the ColumnDividerWidthChanged instead of ColumnWidthChanged ?

    Private Sub DataGridView1_ColumnDividerWidthChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewColumnEventArgs) Handles [b]DataGridView1.ColumnDividerWidthChanged[/b]
        MsgBox("columndividerwidthchanged")
    End Sub

A small update:

if your columns are added at runtime, you might want to declare them WithEvents

Cheers.
