Stepping through datagridview rows in code

Hi All

I have a datagridview bound to a datatable

Due to the use of touch screens I need to be able to scroll the grid in code
in response to a button click
i.e each button touch (click) will move the selection up 1 row

How do I do that

Regards
Steve

You need to change the current cell. I don't remember the exact code
but it'll be something like:

DataGridView.CurrentCell = DataGridView.Rows(RowIndex -1).Cells(0)

of course you need to check that it's not less than 0

Hi Steve,

Thank you for posting!

To simply scroll the DataGridView without changing selected rows, you can
use the property FirstDisplayedScrollRowIndex,

To change the selection while scrolling, you can first get the current
selected row's index by "DataGridView1.SelectedRows(0).Index", then you can
determine the index of next or previous row. Then use following code to
change selection:

DataGridView1.Rows(newindex).Selected = True

Though you may need to set the DataGridView's selection mode to single
selection first:

DataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect
DataGridView1.MultiSelect = False

If there's anything unclear, please feel free to post here.

Steve.

Try to avoid for every bounded control to access it direct. Use the
currencymanager, where you than are playing with the position of that.

I hope this helps,

Cor
