Hi! how can i clear all the cells of the datagridview (when are bounded) this is my scenario:

i use a DataGridView to register products for a sale ticket, but if i decide cancel the ticket i have to clear the products, there is an event, datagridview.clear but it returns "the list cannot be cleared" something like that

If you set the RowCount property to 0, all rows will be removed from the DataGridView. This is equivalent to calling the DataGridViewRowCollection.Clear method.

I tried the above two suggestions, but neither worked. I tried setting the DataSource of the DataGridView to null and that worked.

dataGridView.DataSource = null;

DataGridView1.RowCount = 1

DataGridView1.Rows.Clear()

Cuando cambio el DataGridView1.RowCount se ejecuta automaticamente

Grid_CurCellChange de DataGridView1, tiene que tener encuenta este evento

When change the DataGridView1.RowCount, executes Grid_CurCellChange in DataGridView1 automatically, this event must have

Okay, say you have a table adapter called someTableAdapter and a data set called someDataSet that has a table called someTable.Try something thatlooks like this:

someTableAdapter.FillByClearDataset(someDataSet.someDataSet)

i found a solve for this trick
follow the steps if you deal with the data like this way

first you regally have a connection to some database

2- you got this data into datatable to the datagrid view

like that

con as connection

cmd as command

dr as datareader

tb1 as datatable

now you opened the connection

and put the data into the data table like that

cmdon.Connection = cn
        cmdon.CommandType = CommandType.Text
        cmdon.CommandText = "Select * from table "
        dr = cmd.ExecuteReader
        tb1.Clear()
        DataGridView1.DataSource = tb1
        tb1.Load(drgrid)
        DataGridView1.DataSource = tb1

it'll work with you
