[Andrea Gorin]

protected void btnApplicaFiltro_Click(object sender, EventArgs e)

I have a radgrid within a MS Update Panel.

When I submit with command:

protected void btnApplicaFiltro_Click(object sender, EventArgs e)
{
gridOrdini_DataBind();
}

protected void gridOrdini_DataBind()
{ 
    gridOrdini.Rebind();
}

The first time the grid not update data.

Hi Andrea,

Are you sure that the button performing the postback is also located in the Update panel?
I have also noticed that you set the GridRelationFields in a way that I don't think is supported. Check the paragraph that is above the last code snippet in this link:

I hope this helps.
