Question

How to rename the columns’ headers of datagridview dynamically?

until now I used this code:

dataGridView1.Columns[0].HeaderText = "my_title";

the problem is that Columns[0] might change with time..

How can I iterate on all the Columns Headers and do something like

if (Column.HeaderText=="customer_id") {Column.HeaderText="my_title"} ?

Answer 1

Just use a foreach to iterate over all columns:

foreach(DataGridViewColumn column in dataGridView1.Columns)
{
    if (column.HeaderText=="customer_id") { column.HeaderText="my_title" }
}

This of course would only change the header text for the one column.
If you want to set custom header text for multiple columns you could use a switch instead of the if.
