thank you so much !

[@raduluchian7008]

Thanks to the suggestions that appear for the next clip, the area where you write "dv.RowFilter = "NameFirstname LIKE ... ;" is covered.
So please complete this line of code here.
Thank you in advance!

[@raduluchian7008]

That's what I did and it's not ok:
dv.RowFilter = "lastName LIKE '%"+txtLastNume.Text+"%'";
Where am I wrong?
Again, I can't see your entire line because of the windows that pop up to suggest the other tutorials.

How about if you have two colums being search at the same time in the textbox? like for example we have first name and last name. What is the proper way to do it?

[@TKcode]

Hello, If understood you true. There are a few different ways to handle searching for data in a textbox across multiple columns in a DataGridView in a Windows Forms application, but one common approach is to use the DataView.RowFilter property.
First, you would need to create a DataView object for the DataTable or DataSet that is being displayed in the DataGridView. Then, you can use the DataView's RowFilter property to filter the data based on the text entered in the textbox and the column names of the first name and last name columns.
Here's an example of how you might set the RowFilter property in a button click event handler
private void searchButton_Click(object sender, EventArgs e)
{
string searchText = searchTextBox.Text;
string filter = "(firstName LIKE '%" + searchText + "%') OR (lastName LIKE '%" + searchText + "%')";
DataView dv = new DataView(yourDataTable);
dv.RowFilter = filter;
dataGridView1.DataSource = dv;
}

@@TKcode I want to ask some. I think this will work if you have only one textbox intended for typing keyword as such as searchText. right? what if you have two textbox intended for searching namely "First name" and "Last Name", how do I approach that? i dont know how to do it right. this is my sample code but it only reads the last line of code which is the last name. thankyouu in advanced.
private void btnSearch_Click(object sender, EventArgs e)
{
DataView dv = dt.DefaultView;
dv.RowFilter = "FIRST_NAME LIKE '%" + txtSearch.Text + "%'";
dv.RowFilter = "LAST_NAME LIKE '%" + txtSearch2.Text + "%'";
dgwVaccinee.DataSource = dv;

}

[@TKcode]

@@momusicph9304
private void txtSearch_TextChanged(object sender, EventArgs e)
{
DataView dv = dt.DefaultView;
dv.RowFilter = "Name + Country LIKE '%" + txtSearch.Text + "%'";
dgwCustomers.DataSource = dv;
}
The filter is set using a combination of the "Name" and "Country" columns, and the search criteria is taken from the Text property of a TextBox (txtSearch). The filter uses the LIKE operator to match any rows where the combination of the "Name" and "Country" columns contains the search criteria as a substring.

Hi,
Did someone answer your request? Because I would have the same problem.

[@raduluchian7008]

If it's still useful, I'll send you the solution in my case.
So, it looks like this:
DataView dv = dt.DefaultView;
dv.RowFilter = "NameFirstName LIKE '" + txtSearchEmployee.Text + "%'";
dgvEmployees.DataSource = dv;

Projelerin %90 aynı ID yazmak zorundamıyız. ID otomatik artsın.

[@TKcode]

Bir veritabanında, bir kaydı birbirinden ayırt etmek için, genellikle Birincil Anahtar olarak bilinen benzersiz bir tanımlayıcıya ihtiyaç duyarız. Burada ki Id alanı otomatik artan olarak ayarlanmış. Yani benzersiz olması sağlanmış durumda. Benzersiz bir alanın olması tablolar arası ilişki kurma, güncelleme, silme gibi konularda kolaylık sağlar. Mesela bu örnekte Id alanına göre silme ve güncelleme işlemi yapılıyor. Örneğin isme göre silme işlemi gerçekleştirmek istersek adı John olan kaydı sil dediğimizde varsa tüm John isimli kayıtlar silinecektir.
