It isn't quite hard from turning into 2010 from 2005.

There are very much changes in .Net framework as you may have used 2.0 at last, Currently it's running 4.0 latest.

You will find lots of article published in CP for 2010 from beginning to expert.

Google is always a friend, You will find lots of article on the same world wide too.

it's a very generic question and it can be answered only by ending it to google.

But I am sure It will take some time to adjust, It isn't any drastic change you will soon get adjusted.

Regards,
Hiren.

VS2005 came with .NET 2.0, and all your .net 2.0 code should still work. If you didn't get into generics at the time, they are worth a review.

Changes since 2.0 then have really been add-ons (i.e. not core architecture changes) and language improvements. That's not to say there hasn't been a lot of mostly positive change, but you can apply everything you already know and introduce the new stuff as you go along.
On the ASP side of this there is ASP.NET AJAX, and you should look at WCF in place of WebServices if you use those. You might also want to get your head around ASP.NET MVC3, though I'd personally leave that till last as in lies on top of other new technologies.
As far as the backing-code is concerned the main thing to play with is LINQ in its various guises, and the new LinqDataSource (much cleaner than the SqlDataSource / ObjectDataSource for binding).

.Net 4 has fewer new features, there is good support for parallelism, which is likely to be important as the number of processors goes up.

Hello,
I use this code to upload image and it work very well..

if (!string.IsNullOrEmpty(fupldImage.FileName))
          {
              string savelocationimg = HttpContext.Current.Server.MapPath("~/upload/images/");
              if (fupldImage.PostedFile.ContentLength < 50000)
              {
                  DateTime x = DateTime.Now;
                  string imagename = x.Day.ToString() + x.Month.ToString() + x.Year.ToString() + x.Hour.ToString() + x.Minute.ToString() + x.Second.ToString() + x.Millisecond.ToString();
                  string imgext = fupldImage.FileName.Substring(fupldImage.FileName.LastIndexOf("."));

                  fupldImage.PostedFile.SaveAs(savelocationimg + imagename + imgext);
                  art.ImageURL = "~/upload/images/" + imagename + imgext;
              }
          }

but when I use the same code to upload a video or audio file.. it failure.. this is the code I used..

if (!string.IsNullOrEmpty(fupldVideo.FileName))
{
    string savelocationvideo = HttpContext.Current.Server.MapPath("~/upload/video/");

        DateTime x = DateTime.Now;
        string videoname = x.Day.ToString() + x.Month.ToString() + x.Year.ToString() + x.Hour.ToString() + x.Minute.ToString() + x.Second.ToString() + x.Millisecond.ToString();
        string videoext = fupldVideo.FileName.Substring(fupldVideo.FileName.LastIndexOf("."));

        fupldVideo.PostedFile.SaveAs(savelocationvideo + videoname + videoext);
        art.Video = "~/upload/video/" + videoname + videoext;

}

what is the problem.. and if it is incorrect code for upload video file what is the correct one?
thanks

In neither case do you show any code that is doing anyting with a databas as your subject states.

string videoname = x.Day.ToString() + x.Month.ToString() + x.Year.ToString() + x.Hour.ToString() + x.Minute.ToString() + x.Second.ToString() + x.Millisecond.ToString();

Replace with this

string videoname = DateTime.Now.ToString("ddMMyyyyhhmmssff");

and this

string videoext = fupldVideo.FileName.Substring(fupldVideo.FileName.LastIndexOf("."));

with this

string videoext = System.IO.Path.GetExtention(fupldVideo.FileName);

Please read some books or documentation and learn how to use the language before attempting work with it.

How can I display a pop-up when hovering over a Gridview row?

JTRizos4-Jan-11 6:50

Re: How can I display a pop-up when hovering over a Gridview row?

4-Jan-11 6:50

I have a Gridview application that displays up to 80+ columns showing the various roles a user can have. The first few columns identify the user by name, dept, and job title followed by the various roles each can have, A "Yes" or "No" in a column indicates whether the user has that role. As can be expected, horizontal scrolling means that at some point the columns identifying the user are no longer seen and one gets a grid of Yes and Nos.

BTW, the reason this format is desired is so managers and supervisors can compare users and the roles assigned. As a result, sorting by the columns is important.

I looked into freezing the left most columns but can't find a solution that will work and still allow sorting by any column.

So, I would like to provide a pop-up that displays the user's identity information when one hovers over a row.

I have many possibilites but they use Ajax or have a button in a column to click.

Is this possible? I reviewed lots of articles on this website plus other websites and have not found what I am looking for. I have tried a few things but they do not do what I would like them to do. So, I thought I would ask.

Thanx in advance. Unsure | :~

Of course there are many ways to handle this but essentially you need to add the behavior to the gridcell, either by adding an attribute during rendering, or by JQuery on the client side. Where the info comes from to display is the next point. Again, either construct it and attach it to the grid when being rendered, or perhaps a hidden cell. The popup window is simply a div that is floated on top in the desired location.

Thanx Mark.

This is kinda new to me and I have only used Gridview in the past. I did find an article with a sample program using Datagrid that does what I want it to do. However, I have not yet gotten it to do what I need.

See <a href="http://www.codeproject.com/KB/webforms/Tooltip.aspx?fid=102999&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=26&select=1407335">
[]

My question is should the code used for a Datagrid work for a Gridview? I have editted my application code with code from this article and get no errors but do not know if this article also applies to a Gridview. Confused | :confused:

Thanx again for your advise.

Because all manipulation done through JavaScript so it doesn't matter Gridview or Datagrid. It will work for any control but you have to pass required parameter for javascript function.

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 6:25

Thanx to the feedback I've recieved from this forum, I think I am almost there. Viewing the source I can see that the onmouseover and onmouseout controls have been added to each row in the Gridview as intended. However, I get a "Microsoft JScript runtime error: Object expected" error. I cannot figure out why. The code is as follows:

.aspx code

<script type="javascript">
        function ShowTooltip(LName,FName,JUDesc,JTDesc)
        {   
            document.getElementById("td0").innerText=LName;
            document.getElementById("td1").innerText=FName;
            document.getElementById("td2").innerText=JUDesc;
            document.getElementById("td3").innerText=JTDesc;
            x=event.clientX + document.body.scrollLeft;
            y=event.clientY + document.body.scrollTop + 10;
            Popup.style.display="block";
            Popup.style.left=x;
            Popup.style.top=y;
        }
        
        function HideToolTip()
        {
            Popup.style.display="none";
        }
  </script>
    
    
    <div id="Popup" class ="transparent">
        <div style="BACKGROUND-COLOR:#003366"><center><b>Employee Info</b></center></div>
        <div>
            <table width="100%" border="0" cellpadding="0" cellspacing="0">
                <tr>
                    <td id="td0" align="left"></td>
                </tr>
                <tr>
                    <td id="td1" align="left"></td>
                </tr>
                <tr>
                    <td id="td2" align="left"></td>
                </tr>
                <tr>
                    <td id="td3" align="left"></td>
                </tr>
             </table>
        </div>
    </div>

.aspx.cs code

private void InitializeComponent()
    {
        this.gvRoles.RowDataBound += new GridViewRowEventHandler(this.gvRoles_RowDataBound);
    }

public void gvRoles_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.DataItem != null)
        {
            e.Row.Attributes.Add("onmouseover", "ShowTooltip('" +
                DataBinder.Eval(e.Row.DataItem, "EmployeeNameLast").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "EmployeeNameFirst").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "JobUnitDescription").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "JobTitleDescription").ToString() + "');");
            e.Row.Attributes.Add("onmouseout", "HideToolTip();");
        }
        else
        {
            lblError.Text = "Nothing to report ";
        }
    }

Any advise will be much appreciated. Thanx again for the feedback.

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 6:43

It's better to debug the javascript put the alert inside the method, because i am suspecting for following line. so see the value of :

alert(event.clientX);
alert(document.body.scrollLeft);
alert(event.clientY);
alert(document.body.scrollTop);

I believe may error comes from this line because it's varying browser to browser. So test it and let me here.

Thanks

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 7:05

Thanx Parwej,

I tried this and the alerts do not pop up. Something does flash on the screen so I am guessing it might be the alerts. The JScript message pops up when I hover over a row and in the source the correct onmouseover and onmouseout are highlighted for the correct row. So I think I am close.

I should explain I am testing this using the Debug in Visual Studio 2008.

I'll keep trying to get this to work.

Thanx for your prompt reply.

Parwej Ahamad12-Jan-11 7:17

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 7:17

Hi, alert should popup so write those alerts before the all statement. I believe issue is with those statement. For testing purpose show the tool tip without setting the x, and y. See what's happened. Please test it on different browser.

If you can share your screen on TeamViewer then I can help you and see what's going on.

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 7:49

I took out everything from the JScript except the document.getElementByID statements and still get the JScript runtime error when I hover over a row. The error occurs on ShowToolTip and HideToolTip.

I did notice that I get the "Nothing to report " message from the .aspx.cs code if statement. Not sure why.

I am using IE 8 which is standard for the department and am not sure how to test this without VS 2008 or without placing it in the live environment. I've never used TeamViewer and I doubt it would work due to the firewalls used here. The app I am working on will be internal to our department. Sorry I cannot be more helpful.

Parwej Ahamad12-Jan-11 8:09

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 8:09

Ok, Do step by step :

First comment your existing code then test with simple alert and let me know the status that you are getting alert or not:

public void gvRoles_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if ( e.Row.RowType == DataControlRowType.DataRow )
    {
       e.Row.Attributes.Add("onmouseover", "alert('Display some message');");
    }

     /*   if (e.Row.DataItem != null)
        {
            e.Row.Attributes.Add("onmouseover", "ShowTooltip('" +
                DataBinder.Eval(e.Row.DataItem, "EmployeeNameLast").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "EmployeeNameFirst").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "JobUnitDescription").ToString() + "','" +
                DataBinder.Eval(e.Row.DataItem, "JobTitleDescription").ToString() + "');");
            e.Row.Attributes.Add("onmouseout", "HideToolTip();");
        }
        else
        {
            lblError.Text = "Nothing to report ";
        } */
}

Re: How can I display a pop-up when hovering over a Gridview row?

It works. I get the alert message each time I hover over a row.

Parwej Ahamad12-Jan-11 8:24

Re: How can I display a pop-up when hovering over a Gridview row?

12-Jan-11 8:24

Good Start Smile | :)

Now change your code and test with your method:

//Javascript Method
function ShowTooltip(message)
{   
    alert(message);
        /*    document.getElementById("td0").innerText=LName;
            document.getElementById("td1").innerText=FName;
            document.getElementById("td2").innerText=JUDesc;
            document.getElementById("td3").innerText=JTDesc;
            x=event.clientX + document.body.scrollLeft;
            y=event.clientY + document.body.scrollTop + 10;
            Popup.style.display="block";
            Popup.style.left=x;
            Popup.style.top=y;*/
}

//Row bound event
   e.Row.Attributes.Add("onmouseover", "ShowTooltip('Passed Test Message');");
