I am using a MasterPage site. in default.aspx code-behind, i create many container DIV (ie. each DIV is a SQL result):
HtmlGenericControl div = new HtmlGenericControl("div");
div.Attributes.Add("id", "div_" + postid);
Then create more DIV in code behind (divBottom) programatically and add it to the container DIV, with the following controls inside it:
LinkButton lnkConfirmo = new LinkButton();
lnkConfirmo.ID = "lnkConfirmo_" + postid;
lnkConfirmo.Text = "Foo";
lnkConfirmo.Click += (sender, e) => { UpdateLabel(sender, e, postid); };
Label lblConfirms = new Label();
lblConfirms.ID = "lblConfirms_" + postid;
lblConfirms.Text = "<small><a href=\"javascript:;\">" + GetConfirmTotal(postid) + " pessoas</a> confirmam.</small>";
lblConfirms.Attributes.Add("runat", "server");
And finally add the bottom div to the container.
div.Controls.Add(divBottom);
On the UpdateLabel() method, i am not being able to change Label text when LinkButton is clicked.
public void UpdateLabel(object sender, EventArgs e, int postid)
{
object ctl = (this.FindControl("ContentPlaceHolder1_lblConfirms_" + postid.ToString()) as Label);
HtmlGenericControl ctl2 = (HtmlGenericControl)this.FindControl("ctl00").FindControl("ContentPlaceHolder1").FindControl("lblConfirms_" + postid);
//I tried more combinations of this.
}
I tried Label and HtmlGenericControl because Label is rendering as a span. How can i access that span to change its text, or make this an available control to be accessed? Some controls are available on this.Page.Form (such as some divs, ContentPlaceHolder, ScriptManager and many "Literal), but not the Label as it isn't being rendered as a Control, i guess.
This is the Html output:
<div id="divConfirms_24"><span id="ContentPlaceHolder1_lblConfirms_24" runat="server"><small><a href="javascript:;">190 users</a> confirmam.</small></span></div>
