I want to load data from a row that when I select it by means of a button, I upload it in a format.
For this I am doing it with the CommandName, as if they were coordinates, if you click on such a row it will load this data and so on for all.
But I do not know how to do it in rows and cells with textbox.
if (e.CommandName.ToString() == "clic") {
int indexrow = int.Parse(e.CommandArgument.ToString());
int id = (int)this.gvbuscar.DataKeys[indexrow]["Id"];
To be able to assign the fields from DataGridView to TextBox you have to do it in the following way:
Creating a function that fills the TextBox
public static void LlenarTextBox(int IndiceDGV)
{
TextBox1.Text = DataGridView1.Rows[IndiceDGV].Cells[0].Value.ToString(); //TextBox1 = Ap.Paterno
TextBox2.Text = DataGridView1.Rows[IndiceDGV].Cells[1].Value.ToString(); //TextBox2 = Ap.Materno
TextBox3.Text = DataGridView1.Rows[IndiceDGV].Cells[2].Value.ToString(); //TextBox3 = Nombre
}
IndiceDGV would be the current index of the row you want to select in DataGridView . Then the function is called in the event Click of each button in the following way:
private void Button1_Click(object sender, EventArgs e)
{
LlenarTextBox(0);
}
In this case, the zero ( 0 ) is sent indicating the first row.
To make the code more homogeneous, you could do the following:
private void Button1_Click(object sender, EventArgs e)
{
LlenarTextBox(DataGridView1.CurrentRow.Index);
}
But I'm not sure if clicking on the button this property is full.
To select a record in the gridview you have to use the DataKeyNames and DataKeys
[ASP.NET] GridView - Employee Edition
Analyze in the article:
How the grid is defined the name of the field that identifies the entity in the DataKeyNames
The definition of CommandName="Select" to run the SelectedIndexChanging event
The way to take the selected value
int id = Convert.ToInt32(NombreGrid.DataKeys[e.NewSelectedIndex].Value);
with this you can redirect to another screen to edit the entity
