Hi..
I have three textboxes where i enter first name, middle name and last name and save and edit button. After i save that into db,i retrive from the database and bind to datagridview. I want to merge those three columns as one. And when i click edit button....first,middle and last names should be filled in the corresponding textboxes.

How can i achieve this.

Solution 1

I don't know what kind of database you use, but can't you do something like

"SELECT (Firstname + Middlename + Lastname) AS fullname from [... etc]"

That way you'll receive all 3 columns into one column directly from the datasource.

Then when you click the edit button just select the data separate again, into the textboxes

Oke, if you really want to "merge them" you could do

C#

private void DataGridView_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    foreach (DataGridViewRow row in DataGridView.Rows)
    {
    row.Cells["Firstname"].value += row.Cells["Middlename"].value.ToString() + row.Cells["Lastname"].value.ToString();
    }
    DataGridViewRow.Columns["Middlename"].Visible = false;
    DataGridViewRow.Columns["Lastname"].Visible = false;
}
