I have a webform application in ASP .NET with C # and I want to fill a gridview from the webform.aspx.cs. There is some way to fill it "only" when entering the page, or it must be only with a click event. Could you tell me how to do it? I will greatly appreciate your help Thank you Greetings
This is my Table or Grid in aspx (delete some columns because I use a lot and they are from my work ..)
<asp:GridView ID="dtg_CutWeek" runat="server" AutoGenerateColumns="False" OnRowCommand="dtg_CutWeek_RowCommand">
<Columns>
<asp:BoundField DataField="Year" HeaderText="AÑO">
<HeaderStyle HorizontalAlign="Center" />
<ItemStyle Width="50px" HorizontalAlign="Center" />
</asp:BoundField>
<asp:BoundField HeaderText="MONEDA" DataField="TC">
<HeaderStyle HorizontalAlign="Center" />
<ItemStyle Width="60px" HorizontalAlign="Center" />
</asp:BoundField>
</Columns>
and to do the bindeo of the data I do the following:
dtg_CutWeek.DataSource = ""; // ELIMINO LOS DATOS QUE CONTENGA
dtg_CutWeek.DataSource = dt; // ASIGNO NUEVOS DATOS QUE ESTAN EN MI dt
dtg_CutWeek.DataBind(); //HAGO EL BINDEO DE LA INFORMACION ..
dtg_CutWeek IT IS THE NAME OF MY GRID IF YOU REALIZE IT IS THE ONE I USE TO REFERENCE ON THE BACKEND
In the webform.aspx you should have something like this, where dgvData is the identifier of your GridView.
<asp:GridView ID="dgvDatos" runat="server" AutoGenerateColumns="True">
</asp:GridView>
In your codebehind webform.aspx.cs you should do something similar to this.
protected void Page_Load(object sender, EventArgs e)
{
dgvDatos.DataSource = new Persona().Listar();
dgvDatos.DataBind();
}
You can pass a Dataset from a BD, or direct a data collection as in this example.
