In my ASP .Net web application, the customer has the following requirement. Whenever user tries to close the browser by using the X at the top (the hard close), I want to throw a message popup to user saying that they have not logged out of the application. Are you sure to close? And I want to give them Yes/No options so that if they click on yes, I will let them close otherwise the browser stays open. How can I acheive this?

follow the steps
step1 - In HTML body tag add event onbeforeunload = "CloseX();"

step2 - In HTML header tag add the following Script function.

function CloseX()
{
if(event.clientY < 0 && event.clientX > 100)
{
event.returnValue = "Are you sure to close window?";
}
}

If you use master page add these two steps to master page only.

Hi all,

I am displaying a list of Image thumbnails in a datalist control.
I'm creating the data souce in codebehind (C#) then binding it to my datalist.
The datasource is retieving a list of thumbnail names (strings) from my SQL dB.
This is roughly what my ItemTemplate looks like:(It works fine in IE)

<ItemTemplate>
<a href="linktomypage">
<img src="..\image\<%# DataBinder.Eval(Container.DataItem, "ImageThumbStr") %>" alt="" border="0" />
</a><br />
</ItemTemplate>

This dislays the image as intended in IE but in Firefox, Opera etc. it displays no image. If I put just the text in there (no img tag) it displays that fine.

When I view source code in FF it shows in there the completed img tag with the correct path, but nothing appears on the page?

Is there something obvious I am missing? The databiding for the control is happening on page load.

Any help would be much appreciated.

Many thanks in advance.

Mark

Try displaying the image outside of the link tags and see if that works

Yes,
I have tried that and got the same result, I have tried doing it ousite of the Datalis too in an ASP:Image tag. The image needs to be written to a control from the codebehind idealy.

If you have any suggestions it would be appreciated, I shall keep looking, just hope its not me being stupid...

i download the source file of "ImportExportCSV_src" from codeproject and run this coding to import my excel to sql server. its working fine. but the thing is, i have a description column and user will enter more than 2000 characters. when i m importing, only 255 characters are uploading to the database (i declared in database as nvarchar and length 3000). whats the problem? how to resolve it? - KARAN

coding :

DataColumnCollection tableColumns = dsCSV.Tables[0].Columns;
DataRowCollection tableRows = dsCSV.Tables[0].Rows;
OpenConnection();
foreach (DataRow row in tableRows)
{
primary_key = row.ItemArray[1].ToString();
string sqlinsert = "INSERT INTO " + strTableName + "(";
string sqlvalues = "VALUES (";

object[] rowItems = row.ItemArray;
int ctrColumn = 0;
foreach (DataColumn dc in tableColumns)
{

if (ctrColumn < tableColumns.Count)
sqlinsert += "[" + dc.ColumnName.ToString() + "]" + ",";
if (ctrColumn < tableColumns.Count)
sqlvalues += "'" + rowItems[ctrColumn].ToString().Replace("'", "''") + "',";

ctrColumn++;
}

sqlinsert = sqlinsert + sqlvalues;
cmd = new SqlCommand(sqlinsert, conn);
try
{
rowscreated += cmd.ExecuteNonQuery();
strreturn = rowscreated.ToString();
}
catch (SqlException ae)
{
textbox1.Text=ae.ToString();
}
cmd.Dispose();
}
CloseConnection();

the thing is, when i check the row value (row.ItemArray) it can hold only 255 characters. so i cant upload the full 2000 characters. how to proceed this? help me ! - KARAN

You can link to it in your page instead of putting script in your page, but if the file is not available to an end user, then they can't use it. So, you cann't hide it.

even if u give the path instead of putting js code in the aspx page, when u save the page that .js file also get saved in the disk.

i dont want even this.

Thanks For the Reply.

Well, as I said, you are screwed. Welcome to web development. If you don't give the user your js code, they can't run it. You can't protected it. You can obsfucate it, but that's about it, people can still reuse it.
