Hi all,

Can anyone suggest me how to write the confirm box in code behind
and i want to get the return value whether the user clicked 'ok' or
'cancel',
Depending on that i need to process further using if else .
"I want to pass one value which is from database to confirm message."
for ex: return confirm(10 elements)
This 10 in the message is getting from database
Thats y i am using this calling from code behind.

Thanks in advance,
Deepthi

If I understand, You need bellow
in your aspx page write following

XML

<script language="javascript" type="text/javascript">
    function confirmSearch() {
        if (confirm("Are you sure you want to search!"))
            return true;
        return false;
    }
</script>

and in Button do the followings

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return confirmSearch()" OnClick="searchfromDate" />

Hope it help

write the script inside the aspx page, you can write it in heading or body.. if you design a simple page having one button and the code i write, that definitly works because i checked it.

Hey,

Consider the code below :

C#

string messageFromDatabase = "Are you sure you want to do this?";
StringBuilder javaScript = new StringBuilder();
javaScript.Append("<script type=\"text/javascript\">\n");
javaScript.Append("function doConfirm(){\n");
javaScript.Append("\tif (confirm('");
javascript.Append(messageFromDatabase);
javaScript.Append("'){\n");
javaScript.Append("\t\t// code when the user clicks OK\n");
javascript.Append("\t} else {\n");
javaScript.Append("\t\t// code when the user clicks cancel\n");
javascript.Append("\t}\n");
javaScript.Append("}\n");
javaScript.Append("</script>\n");

You can add the script to the page in Page_Load()

C#

Page.ClientScript.RegisterClientScriptBlock(typeof(Page),
    "confirmationScript", javaScript.ToString());

Hope it helps,

Cheers, Eduard

hi Eduard.
I cant get the solution...
My actual requirement is,
In my page, On clicking of search button i need to show this confirmation message.This message is from database.
After that i want to know user clicked is yes or no.
if user clicked yes,i want to retrieve list of items from database

I don't see why you cannot get that working with the code above. Have you tried to implement it?

Deepthi Aravind 22-Apr-11 6:26am

ya..
I hv added this line to my buttin click event
string messageFromDatabase = "Are you sure you want to do this?";
StringBuilder javaScript = new StringBuilder();
javaScript.Append("<script type=\"text/javascript\">\n");
javaScript.Append("function doConfirm(){\n");
javaScript.Append("\tif (confirm('");
javascript.Append(messageFromDatabase);
javaScript.Append("'){\n");
javaScript.Append("\t\t// code when the user clicks OK\n");
javascript.Append("\t} else {\n");
javaScript.Append("\t\t// code when the user clicks cancel\n");
javascript.Append("\t}\n");
javaScript.Append("}\n");
javaScript.Append("</script>\n");

and added the clientscript also..

Did you READ my answer? Add the script in the page load event and add a client script handler that calls the doConfirm function

try this one;

MIDL

ScriptManager.RegisterStartupScript(this,this.GetType(), "Message","confirm('Number of rows ');", true);
