Display a javascript alert (or run script) from code behind page.

Using Response.Write from an asp.Net web form might work but has some side effects so using the .Net ClientScriptBlock will allow you to insert your javascript cleanly. Here is a sample from some real code I wrote.

 

// Any any function that runs on PageLoad
string csName = “alert”;
string js = “alert(‘Customer has abuse tickets’);”;
ClientScriptManager cs = Page.ClientScript;
if (!cs.IsStartupScriptRegistered(csName))
{
cs.RegisterStartupScript(this.GetType(),csName, js, true);
}
