asp messagebox

i'm not sure whether you could use yes/no without a js library but you might try wuth confirm

ScriptManager.RegisterStartupScript(this, this.GetType(), "confirm", sScript, true);

Select allOpen in new window

ok how can i code so when the user clicks the yes or no button?

Check this

protected void showMessageBox(string message)
    {
        string sScript;
        message = message.Replace("'", "");
        sScript = String.Format("confirm('{0}');", message);
        ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", sScript, true);
    }

Select allOpen in new window

use a library like jQuery. here is a demo

that works and display the yes and no, is they way when the user clicks yes that i can code in c# for that button or javascript?

i need to code in c#

Yes you can do that

sScript = String.Format("if(confirm('{0}')) { alert('Code goes here if user click on YES');} else {alert('Code goes here if user click on NO/CANCEL');}", message);

this code fine:

protected void showMessageBox(string message)
    {
        string sScript;
        message = message.Replace("'", "");
        sScript = String.Format("confirm('{0}');", message);
        ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", sScript, true);
    }


now in c# code how do i code if the user click on yes or no?

can i have i redirect to a page if yes?

sScript = String.Format("if(confirm('{0}')) { alert('Code goes here if user click on YES');} else {alert('Code goes here if user click on NO/CANCEL');}", message);

You can not do this. You need write the code in javascript as I mentioned above

Yes you can redirect

sScript = String.Format("if(confirm('{0}')) { window.location='your_page.aspx';} else {alert('Code goes here if user click on NO/CANCEL');}", message);

ok how can i do a redirct in java when the user clicks the yes button?

and if the user select no nothing must happen

got an erorr:

rror: Sys.WebForms.PageRequestManagerServerErrorException: Input string was not in a correct format.

Show your showMessageBox function

   protected void showMessageBox(string message)
    {
        string sScript;
        message = message.Replace("'", "");
        sScript = String.Format("if(confirm('{0}')) { window.location='/login/home.aspx';} else {}", message);  
        ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", sScript, true);
    }

Try below code. I am just checking the error you are getting is bocoz of "/' and then let me know
protected void showMessageBox(string message)
{
        string sScript;
        message = message.Replace("'", "");
        sScript = String.Format("if(confirm('{0}')) { window.location='home.aspx';} else {}", message);  
        ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", sScript, true);
}

still erorr :(

erorr here

sScript = String.Format("if(confirm('{0}')) { window.location='home.aspx';} else {}", message);
