Re: How to find the row in the gridview that was selected - JavaScript Discussion Boards

Actually, I wasn't aware about that. Anyway, people learn from their mistakes, right? Big Grin | :-D

Help people,so poeple can help you.

Fair enough - we all learn things we didn't know (I won't embarrass myself by pointing out the "beginners mistake" I made a few days ago!)

There are two useful fields on the response you get back from an Ajax call - responseXml (which you've already discovered), and responseText. Now if you are indeed sending Xml back, then responseXml will be correctly filled in, and responseText will contain exactly the same.

However, if in your server side code, you do a simple Response.Write("Hello World"), then IIRC responseText will contain this, responseXml will be empty (you'll need to check that last empty point - been a while!)

What this means is that you can write ANYTHING you want back and pick it up out of responseText - one neat trick I've employed in the past is to make DataGrids render as part of an ajax call, write the Html back on the response, pull it out of the responseText and slap in into a div's innerHtml property.....

can u help on this?

You'll likely have to write a webservice and then catch the return results. Look for a 3rd party tool or search google.

I have a gridview of employee jobs.
One job row gets selected and some items from the row and some items from the database populate a space below the Gridview on an aspx page.
total hours is in the gridview row. The user enters the payrate into one of the fields on the aspx page. user enters another field for overtime rate. There is a DropdownList that has hourly and Hourly+. Stakeholder does not want the total hours displayed below the gridview.

After the amounts are entered the operator selects from the dropdownlist.
from a client side Javascript I need to find the row in the Gridview that was selected, get the total hours from the column of that row, then compute the total pay.

The problem is I don't know how to locate the row that was selected from the Gridview.

It is not the opject that is firing the current event.

Can you help with a small snippet.

Thanks..

Try using this Example :

<%@ Page language="C#" %>

void CustomersGridView_SelectedIndexChanged(Object sender, EventArgs e)
{

// Get the currently selected row using the SelectedRow property.
GridViewRow row = CustomersGridView.SelectedRow;

// Display the company name from the selected row.
// In this example, the third column (index 2) contains
// the company name.
MessageLabel.Text = "You selected " + row.Cells[2].Text + ".";

}

void CustomersGridView_SelectedIndexChanging(Object sender, GridViewSelectEventArgs e)
{

// Get the currently selected row. Because the SelectedIndexChanging event
// occurs before the select operation in the GridView control, the
// SelectedRow property cannot be used. Instead, use the Rows collection
// and the NewSelectedIndex property of the e argument passed to this
// event handler.
GridViewRow row = CustomersGridView.Rows[e.NewSelectedIndex];

// You can cancel the select operation by using the Cancel
// property. For this example, if the user selects a customer with
// the ID "ANATR", the select operation is canceled and an error message
// is displayed.
if (row.Cells[1].Text == "ANATR")
{

e.Cancel = true;
MessageLabel.Text = "You cannot select " + row.Cells[2].Text + ".";

}

}

Hi!
I've given the source code for a web site. I've to host it to localhost(in XAMPP) and test the site. I've installed XAMPP and copied whole source code to htdocs folder of XAMPP installation. Now I've to run the website from localhost. For this I need to know which file I've to call from the browser. Where will it be embedded? Sorry if this is a silly question. I don't know anything about web programming.

Look for any file marked Index or Default.
That will be the start page that the browser looks for.

Sorry Dave, but I can't just let that one slide....

I think you're getting a little confused by the default document (which is indeed usually called index or default, or even login!) - this is set in IIS / Web server to determine which file to send to the client when none is specified, so if your start page is http://blah.de.nobbs/default.aspx then entering http://blah.de.nobbs is sufficient - IIS then looks at what the default doc is and serves that back to the client.

Has nothing at all to do with the browser above and beyond making a request and recieving a response.

Hi
I have an array of objects that store information. call it guests. Lets say I have 5 guests added and I delete guest[2] then there will be 4 guests left. The array index does not auto correct in JavaScript. The values that are left are stored as:

guest[0]
guest[1]
guest[3]
guest[4]

Confused | :confused:

how can I correct this to:

guest[0]
guest[1]
guest[2]
guest[3]

I thought of using a temp array, copy it over to a correct index the copy the array back to the original, but this seems wrong somehow.

Ethius - I think you are looking for "splice()". A good, short, and to the point article was posted on StackOverflow: http://stackoverflow.com/questions/5237387/algorithm-to-re-index-an-array-of-objects-after-insertion-or-drag-n-drop-order

Using Splice you can insert and delete array elements with the added benefit of auto-reindexing.

Thanks. I used splice() and it worked Big Grin | :-D

       {
         return;
        }

        for(var n=i;n<(ar.length-1);n++)
        {
            ar[n]=ar[n+1];
        }

         ar.pop();
    }

How would I alert the user if they selected more than one COP1000 and in another instance alert the user if they selected more than one COP 2830. Right now it notifies the user if they selected more than one class.

JavaScript

<script type="text/javascript" charset="utf-8">
    var p = 0;
    $(document).ready(function () {
        $('input:checkbox').click(function () {
            var COP1000 = $(this).attr('data');
            if ($('input:checkbox:is_checked').attr()) {
                p++;
            }
            if (p >= 2) {
                alert('You can only select this class once');
                return false; 
            }
        });
    });
<script>

Below are checkboxes with data being the name of the class

HTML

<input name="class[]" data="COP1000" value="<tr><td>COP1000 <td>8:00AM-9:00AM 
</td><td>MWF </td><td>Sanford </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>
<input name="class[]" data="COP1000" value="<tr><td>COP1000 <td>11:30AM-12:00PM
</td><td>TTH </td><td>Altamonte </td><td>3</td></tr>" type="checkbox" class="auto-
style88" />

<input name="class[]" data="COP2830" value="<tr><td>COP2830 <td>11:00AM-12:00PM 
</td><td>MWF </td><td>Sanford </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>
<<code><code></code></code>input name="class[]" data="COP2830" value="<tr><td>COP2830 <td>6:00PM-8:45PM 
</td><td>T </td><td>Altamonte </td><td>3</td></tr>" type="checkbox" class="auto-
style88"/>

What's the question? The posted code looks like it should work (though I don't really know jQuery).

I'm not sure about putting markup in the value attribute of a checkbox, that looks dodgy, though not relevant to this issue.

XML

<script type="text/javascript">

$(function(){

    $("input:checkbox").click(function(){

       var data=$(this).attr("data");
        var count=$("input:checkbox:checked[data="+data+"]").length;

        if(count>=2)
        {
            alert(data+" select more than one");
            $(this).removeAttr("checked");
            }
        });
    });

</script>

what are the very basic, common commands of JavaScript. Give with exercises.
