How to assign a value to texbox inside a gridview as itemTemplate

Question

i have a gridview with a item Template with a textbox, so i create a datatable in memory and assign to the gridview, but the values doesn't assign to the textbox in the item template.

How i assign a value of my datatable to the control inside grid.

grdNotas.Rows(numero).Cells(2).FindControl("txtf1")

Dim tbnotasAlumnos As New DataTable

    For Each fila As DataRow In tbAlumnnoCurso.Rows
        tbnotasAlumnos = conexion.consultaNotaMateriaAQP(tbAlumnnoCurso.Rows(numero)(0).ToString, ddlmaterias.SelectedValue, txtQuimestre.Text, txtparcial.Text)
        'fill the textboxes
        grdNotas.Rows(numero).Cells(2).FindControl("txtf1")
        numero = numero + 1
    Next

how i can do it?

You need not only to find the control, but also to cast it to specific type. That will give you an access to textbox's properties

Dim txt As TextBox = CType(grdNotas.Rows(numero).Cells(2).FindControl("txtf1"), TextBox)
txt.Text = "value"
