Hi,

I have created a web page that contains 4 fields and a filter button.
Based on the values entered in the textboxes a report will be generated.
The report is a grid view.This a report that contains issues.

When I click on any issue in the report it will show you all the details of that issue it has a close button.
When I click on a close button it will close the issue,(means it will delete the issue from the report).

And now the problem is I want to put an alert on a close button so that it will show an alert when the issue is closed.

I have tried the following way.

1)Response.Write("<script>alert('Issue has been closed')</script>");

When I tried this it is showing me the alert message but I cannot see the screen backside.
It is showing me a white blank page when the alert pops out.

I have tried the following javascript funtion,but no use.

XML

public static class Alert
{
/// <summary>
/// Shows a client-side JavaScript alert in the browser.
/// </summary>
/// <param name="message">The message to appear in the alert.</param>
public static void Show(string message)
{
// Cleans the message to allow single quotation marks
string cleanMessage = message.Replace("'", "\\'");
string script = "<script type=\"text/javascript\">alert('" + cleanMessage + "');</script>";
// Gets the executing web page
Page page = HttpContext.Current.CurrentHandler as Page;
// Checks if the handler is a Page and that the script isn't allready on the Page
if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert"))
{
page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script);
}
}
}

Can any one please help me regarding this .
~~Its very urgent.~~

Thanks in advance

Solution 1

attach a script to your aspx file with an alert function like this

function ShowMessage(message)
{
   alert(message);
}

call the function on the clientclick event of the close button

<asp:button onclientclick="ShowMessage('Issue will be deleted')" xmlns:asp="#unknown">

You can also try this for confirmation of delete issue.

XML

<script language="JavaScript">
      <!--
            function confirm_delete()
            {
                  input_box=confirm("Are you sure you want to delete this issue?");
                  if (input_box==true)
                 {
                     // Output when OK is clicked
                      return true;
                  }
                  else
                  {
                       // Output when Cancel is clicked
                      return false;
                  }

            }
      -->
</script>

And then call the function on the clientclick event of the close button

C++

<asp:button onclientclick="return confirm_delete ()" xmlns:asp="#unknown">
