DevExpress modify label in templateitem - devexpress

Question

I am working with DevExpress platform.
I have a axGridview that contains an ItemTemplate with a Label, i need just modify in every row with value.
With asp.net and GridView i used to manage FindControl in RowDataboundEvent, but here i really need help. The FindCellTemplate function always returns NULL.
here my code:
<dx:ASPxGridView ID="gvRecapiti" ClientIDMode="Static" ClientInstanceName="gvRecapiti" Width="100%" runat="server" AutoGenerateColumns="False"
OnHtmlRowCreated="gvRecapiti_HtmlRowCreated" >
<Columns>
<dx:GridViewDataColumn Caption="RecapitoTipo" >
<SettingsHeaderFilter>
<DateRangePickerSettings EditFormatString=""></DateRangePickerSettings>
</SettingsHeaderFilter>
</dx:GridViewDataColumn>
<dx:GridViewDataTextColumn FieldName="DescRecapito" >
<DataItemTemplate>
<dx:ASPxLabel ID="lblRecapito" ClientIDMode="Static" runat="server" ClientInstanceName="lblRecapito" Text='<%# Eval("DescRecapito") %>' ></dx:ASPxLabel>
</DataItemTemplate>
</dx:GridViewDataTextColumn>
</Columns>
</dx:ASPxGridView>
using DevExpress.Web;
namespace ProvaGridItem
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack != false)
{
BindGrid();
}
}
private void BindGrid()
{
List<Recapito> R = new List<Recapito>();
for (int i=0;i<5;i++)
{
Recapito Recapito = new Recapito();
Recapito.DescRecapito = "Recapito: " + i;
Recapito.RecapitoTipo="RecapitoTipo: "+i;
R.Add(Recapito);
}
gvRecapiti.DataSource = R;
gvRecapiti.DataBind();
}
protected void gvRecapiti_HtmlRowCreated(object sender, DevExpress.Web.ASPxGridViewTableRowEventArgs e)
{
if (e.RowType != DevExpress.Web.GridViewRowType.Data) return;
ASPxLabel lblRecapitoTipo = (ASPxLabel)gvRecapiti.FindRowCellTemplateControl(e.VisibleIndex, null, "lblRecapitoTipo");
lblRecapitoTipo.Text = "Label Updated by code!!";
}
internal class Recapito
{
public string RecapitoTipo { get; set; }
public string DescRecapito { get; set; }
}
}
}

Answer 1

(ASPxLabel)gvRecapiti.FindRowCellTemplateControl(e.VisibleIndex, null, "lblRecapitoTipo");
This should have column to find control. so that first get column in a variable and then find template control of that column.Please go through with below code.
GridViewDataTextColumn col = gvRecapiti.Columns["lblRecapito"] as GridViewDataTextColumn;
ASPxLabel lblRecapitoTipo = gvRecapiti.FindRowCellTemplateControl(e.VisibleIndex, col , "lblRecapitoTipo") as ASPxLabel;
and then you can change lblRecapitoTipo label properties as you want.In your case it is
lblRecapitoTipo.Text = "Label Updated by code!!";
