Using Alert In Response.Write Function In C#

Feb 23, 2011

I have database code like this

try
{
string strConnectionString = ConfigurationManager.ConnectionStrings["SqlServerCstr"].ConnectionString;
SqlConnection myConnection = new SqlConnection(strConnectionString);
myConnection.Open();
string hesap = Label1.Text;
string musteriadi = DropDownList1.SelectedItem.Value;
string avukat = DropDownList2.SelectedItem.Value;
SqlCommand cmd = new SqlCommand("INSERT INTO AVUKAT VALUES (@MUSTERI, @AVUKAT, @HESAP)", myConnection);
cmd.Parameters.AddWithValue("@HESAP", hesap);.......

It works fine but what I want, in the catch function, is to call the javascript alert function.

I've tried this

Response.Write("<script language=javascript>alert('ERROR');</script>);

But there is an error

How can I show error message in javascript alert function?

MVC :: Razor Function And Lambda Functions / Write A Function To Reuse Some Functionality?

Mar 8, 2011

I would like to write a function to reuse some functionality that I repeat over and over...

For example:

[code]....

What's changing, in every field, is only the lambda function to get the current field to edit (Name, City, Address, etc...).

What is the best method? Or better: is there ANY method to extract a generic function?

Combine Alert Popup In Save As File Function In C#?

Jul 17, 2010

I'm tring to write a function that need to save a file (in csv) and has a condition.

it's something like that:

If the file is small then 1MB then I want to pop up an alert in javascript and then continue with the save as file commands.

What I did was:

if(...)
{
}
else
{
ClientScript.RegisterStartupScriptBlock(...alert('aaa')...);
}
Response.ContentType = "text/csv";
Response.AppendHeader("Content-Disposition","attachment; filename=file.csv");
Response.TransmitFile("FILE.csv");
Response.End();

the save as works fine. but the alert wont popup in the else case. I tried RegisterStartupScript. I tried many options. But it seems that the response.end is stops the clientscript from happening.

I am writing in c# asp.net (ajax enabled website, but not in use), visual studio 2005.

C# - Can I Zip Response.write

Jan 21, 2010

Let me explain better than what the question state. I dynamically generate a KML file from an aspx page and use routing to change the url so I can access myapp.com/mykml.kml and the download starts. I use Response.write() in the aspx page to send the data and it work flawlessly. But there is a zipped version for KML files which is KMZ and I am wondering if I can still use my aspx page to serve a KMZ instead of a KML. Since I do not use a file I cannot "zip" it. Is there a way to zip the stream and output it in the Response.Write()?

Response.Write JSONP Using JQuery And WCF?

Nov 18, 2010

UPDATE:

The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

when i try to access wcf service i get this error: the reason is HttpContext.Current is null, what should i do in this case?

Object reference not set to an instance of an object.

System.Web.Script.Serialization.JavaScriptSerializer s = new System.Web.Script.Serialization.JavaScriptSerializer();
Person p = new Person() { FirstName = "First name", LastName= "last name" };
string json = s.Serialize(p);
System.Web.HttpContext.Current.Response.Write("jsoncallback" + json);} //error

Correct Usage Of Response.Write() In C#?

Jan 3, 2011

I am trying to force a download of an XML file when the user visits a page.

This is the code I am using

public partial class GenerateTemplate : LayoutsPageBase
{
protected void Page_Load(object sender, EventArgs e)
{
//.............
//Going about generating my XML
//.............
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=template.xml");
Response.Write(xmlDoc.InnerXml);
Response.Flush();
Response.Close();
}
}

I am facing a problem that my download window hangs indefinitely, without ever completing the download/Open of the file.

What am I doing wrong? Am I not disposing any objects or closing any connections here?

Web Forms :: Response.Write Breaking CSS?

Jan 5, 2010

I have an aspx page and when the user clicks a button the following code runs:

Write Binary Data As A Response In MVC Web Control?

Apr 28, 2010

I am trying to get a control (not a controller -- a subclass of System.Web.UI.WebControls.WebControl), that can be used that I wrote for ASP.NET to work in an ASP.NET MVC environment. Normally, the control does the normal thing, and that works fine

Sometimes it needs to respond by clearing the response, writing an image to the response stream and changing the content type. When you do this, you get an exception "OutputStream is not available when a custom TextWriter is used".

If I were a page or controller, I see how I can create custom responses with binary data, but I can't see how to do this from inside a control's render functions. To simplify it -- imagine I want to make a web control that renders to:

<img src="pageThatControlIsOn?controlImage">

And I know how to look at incoming requests and recognize query strings that should be routed to the control. Now the control is supposed to respond with a generated image (content-type: image/png -- and the encoded image). In ASP.NET, we:

Response.Clear();
Response.OutputStream.Write(thePngData); // this throws in MVC
// set the content type, etc
Response.End();

How am I supposed to do that in an ASP.NET MVC control?

AJAX :: Can Use Response.write In Conjunction With An UpdatePanel

Feb 11, 2010

I want to bring up an Alert messagebox if a user does not fill in a field on my webform before clicking a submit button on the form. I also want to use an UpdatePanel because it makes it a smoother user experience. But I am experiencing a conflict with

response.write("<script>alert('fill in Comment before submitting');</script>");

and the UpdatePanel. If I remove the Updatepanel then I can use my Alert message above but it loses the page temporarily until the user clicks "OK" on the messagebox. My alternative - using the UpdatePanel - was to add a label to the webform where if a user does not fill in the requested info - a label would display text giving the same message - very smoothly with the UpdatePanel. But the label is not modal like the Alert message.

Is there a way I can use response.write in conjunction with an UpdatePanel? The webform is fairly basic. It has a couple of asp.net textboxes and labels and an asp.net button control. I guess I could use a "required" label, but I like the modal property of the Alert message better.
