Hi,
Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
Migrate C1Window to C1Dialog.
Using C1Dialog from C1.Web.Wijmo.Controls.48.dll

string script = string.Format(@"window.{0}.Show({{ title:'{1}',message:'{2}',icon:{3},buttons:{4}, width:'{5}', height:'{6}' }});", ClientID, Title, System.Web.HttpUtility.JavaScriptStringEncode(Message), (int)Icon, (int)DialogButtons, Width.ToString(), Height.ToString());
clientScripts.Add(script);
call to Show:
window.ctl00_MessageDialog1.Show({ title:‘Error’,message:‘Error buscando tránsitos’,icon:2,buttons:1, width:‘500px’, height:‘250px’ });
height:‘250px’ for c1dialog ? ‘250px’ with unit px or only 250 ?
Show javascript fragment:
w.c1dialog({
title: title,
modal: true
});
if (width) {
w.c1dialog("option", "width", width);
}
if (height) {
w.c1dialog("option", "height", height);
}
w.c1dialog({ position: 'center' });
w.c1dialog("open");
controls.btnAccept.focus();
