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

[Parwej Ahamad]

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.

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.

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 ";
    } \*/

}

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

Good Start :) 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');");

Tried this and got the "JScript runtime error:Object expected" message on each row hovered.

Agreed but I don't have a messenger here. I changed the and the ShowTooltip(message) worked. No runtime error. However, when I put the code back to the way it was I don't get the runtime error but I do get a webpage message with a number in it. When I press the OK button, it goes through a series of three messages having different numbers as I press OK after each one. Hovering over a row starts the series of messages over again. Any idea? I know this is abstract and you probably have better things to do but you have been a big help.</x-turndown>

Your last message is broken so send me direct email with your last message on my person id: ahamad.parwej@gmail.com

I'll try this again I changed the "" to "<script type="text/javascript">" and I do not get the runtime error anymore for the ShowTooltip(message). So, I changed it back to the original code and no longer get the runtime error. However, I get a webpage message window with a number in it. Pressing OK brings up another webpage message with another number in it. This happens about 3 times. Hovering over a row restarts this series of messages with a different number in each. Any ideas? I know this is abstract but you have been a big help on this. I do not have a messenger here and I know this is cumbersome.</x-turndown>

Can you send me print screen of that error message so I can take a look?

With help from this forum (Thanx Parwej Ahamad) I got what I needed. I am including the code here in case it can help others. The application has 119 columns and this Popup displays the employee name, job unit and job description by hovering over any row as the user scrolls horizontally. This was based on A Simple DataGrid Row Tooltip For Beginners.[^] .aspx

<!-- Script and Div to set up the Popup with Employee Info -->
<script type="text/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.documentElement.scrollLeft;
y=event.clientY + document.documentElement.scrollTop + 5;
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 for Popup with Employee Info */
public void gvRoles_RowDataBound(object sender, GridViewRowEve
