I have a form that has a datagridview. Some columns are bound to the datasource, and some are not. The ones that are not I populate from an event. When a new row is added, I use the CellValidating event to populate these. But if I am displaying the records from the datasource (using a filter), my CellValidating is not firing therefore not populating the columns. What is the best event/method to use to get these values populated when the data is displayed from the datasource.

Thanks

Hi,

Do you mean you want to add the columns when user adding a new row? There are some events fired when adding a new row. For example, DataGridView.RowsAdded event.

void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)

{

if (!dataGridView1.Columns.Contains("test"))

{

DataGridViewTextBoxColumn txt = new DataGridViewTextBoxColumn();

txt.Name = "test";

txt.HeaderText = "test";

dataGridView1.Columns.Add(txt);

}

}

If I misunderstood you, or you have further questions, please feel free to tell me.
