Nothing different...
Like you are calling an inline java script function..

in page load give
Butten1.Attributes.Add("onclick","javascript:ValidateControl()")
thats all

To succeed, we must first believe that we can.

Only, you don't use the "javascript:" protocol when you don't put the code in an url.

Button1.Attributes.Add("onclick","ValidateControl();")

or in framework 2:

Button1.OnClientClick = "ValidateControl();"

Hi,

Everybody post their problem to get help only.

The point here that your subjeline should be clear.

Your subject line should depict your problem briefly.

Your subject line coulde "Implement Sorting in gridview" or "Problem in sorting with gridview".

"Need Help" dosent show anything and many of the people are not keen to open such type of thread and hence the chances you get the solution is less and response time is more.

I hope you got my point.

Thanks and Regards,

The sorting is usually done before the data gets to the gridview. If you are using a sqldatasource or an objectdatasource those controls will sort the data for you. If you are not using those controls you need to sort it when the data is returned from the database.

Hope this helps.

There is a session timeout event in the global.asax, but this is not reliable. Still it is the best you can do. Note it only works if you are using inProc sessions. If you are using session server or sql to store session the event in the global.asax will not fire.

I don't understand why you can't check in Page_load...

If Session.IsNewSession Then Response.Redirect("login.aspx")

I have a simple problem that I need to know either the best solution for or a list of the options.

I need to export data from a database into a an excel spreadsheet. I will more than likely use a stored procedure to create the result set and then use a datareader to bind to whatever object you suggest.

The spreadsheet needs to be emailed to a recipitent so I would prefer it as a memory stream object so I have the flexibility to do this.

Thanks

Hmm looks like a lot more code than I was expecting. Also doesn't look ideal for my situation eg opening instances of excel etc.

Someone else suggested exporting to XML or CSV and then importing to Excel?? Any ideas on this?

In either case, if you want an Excel object in memory, to be attachable in Email, you need to instantiate using interop.

You have to write javascript that captures the keypress, works out what it is, and calls teh script to submit with that button.

<br />
     TextBoxThatIsFocuseWhenEnterPressed.Attributes.Add("onKeyPress", "doClick('" + ButtonToTriggerOnEnterPress.ClientID + "',event)")

Put that in the page load event.

And then this in the page

// Default button code<br />
function doClick(buttonName,e)<br />
    {<br />
//the purpose of this function is to allow the enter key to <br />
//point to the correct button to click.<br />
        var key;<br />
        <br />
        if(window.event)<br />
            key = window.event.keyCode;     //IE<br />
        else<br />
           key = e.which;     //firefox<br />
    <br />
        if (key == 13)<br />
        {<br />
            //Get the button the user wants to have clicked<br />
            var btn = document.getElementById(buttonName);<br />
            if (btn != null)<br />
            { //If we find the button click it<br />
                btn.click();<br />
                if(window.event) event.keyCode = 0;<br />
                <br />
            }<br />
        }<br />
   }

If it were me I would put the javascript code in a sperate js file and then reference it into the page. Why? Chances are you will use this elsewhere once youv'e got the function so it saves posting the code into each page.

If you didn't know you do it like this

<br />
    <script type="text/javascript" src="JavaScript/DefaultButtonScript.js"></script>

Another option, you can define a default button for your page (other containers support this as well) which creates the needed JS for you.

The end result (rendered JS) would look like this:
onkeypress="javascript:return WebForm_FireDefaultButton(event, 'SomeButton')"

It's pretty much what was offered, just an easier implemenatation if it works for your particular situation.
