[Resolvido] Problemas paginação Codebehind C#

[Cazanova 0]

A paginação é escrita perfeitamente, mas a navegação não funciona e não encontro onde está o erro. Se puderem me ajudar.

 

 

List.aspx

Depois de definir o novo index no evento PageIndexChanging você deve dar um DataBind na sua grid para carrega-la novamente. E normalmente utilizamos o evento PageIndexChanging e não o OnPageIndexChanging. Mas tente o seguinte:

 

 

protected void gvSession_OnPageIndexChanging(Object sender, GridViewPageEventArgs e)
{
	gvSession.PageIndex = e.NewPageIndex;
	gvSession.DataBind();
}
