retrieving anchor's color on server side

I am retrieving the color of the html anchor control on the server side. following is my tried code
Design:
<a id="lkdelete" onclick="SingleDel(this);" runat="server" style="font-weight:bold ">Delete</a>
Javascript:
function SingleDel(ctrl)
{
var row=ctrl.parentNode.parentNode;//to get row containing image
var rowIndex=row.rowIndex;//row index of that row.
var hsingle_del=document.getElementById('<%hsingle_del.ClientId %>');
hsingle_del.value=rowIndex;
var modalPopupBehaviorCtrl = $find('bmpe');
modalPopupBehaviorCtrl.set_PopupControlID("pnlPopup");
modalPopupBehaviorCtrl.show();
}
Vb.Net:
Dim pid As String = ""
For Each r As GridViewRow In gridview.Rows
Dim lnk As HtmlAnchor = CType(r.Cells(1).FindControl("lkdelete"), HtmlAnchor)
If lnk.Style("Color") = "Red" Then
pid = CType(r.FindControl("lblposid"), Label).Text
End If
Next
here at 1st row of gridview the color is red . but it returns "". any solution?

make few changes on your code. add a hidden field on your page.
function SingleDel(ctrl)
{
var rowIndex=ctrl.offsetParent.parentNode.rowIndex-1;
var hsingle_del=document.getElementById('<%=hsingle_del.ClientId %>');
hsingle_del.value=rowIndex;
var modalPopupBehaviorCtrl = $find('bmpe');
modalPopupBehaviorCtrl.set_PopupControlID("pnlPopup");
modalPopupBehaviorCtrl.show();
}
vb(instead of for loop)
pid = CType(gridview.Rows(hsingle_del.Value).FindControl("lblposid"), Label).Text

Gridview Footer row textbox in JavaScript

I have been accessing the rows of Gridview quite easily using javascript.
But when I try to add a new row and then try to access, then the code is not working.
Is there a way by which I can access the footer row text box?
Below is my code which works well when edit mode text boxes are to be accessed. Please donot post any link.
function OnSelectIndexChange() {
var drpdwn = document.getElementById("ddlSelectUnderwriterCond");
var drpdwnValue = drpdwn.options[drpdwn.selectedIndex].text;
var gridview = document.getElementById("<%= StandardUndewritingGrid.ClientID %>");
for (var i = 1; i <= gridview.rows.length; i++) {
var labels = gridview.rows[i].cells[0].getElementsByTagName("input")[0].value;
var txtbx = gridview.rows[i].cells[0].children[0];
if (drpdwnValue != '-- Select --')
txtbx.value = labels + '<^>' + drpdwnValue + '<^>';
}
}

I have just figured out a way of accessing the footer row and code is working fine so I am posting as it might help someone as well:
var flabels = document.getElementById('<%=((TextBox)gridname.FooterRow.FindControl("controlname")).ClientID %>');
if (flabels != null) {
}

It works by simple logic:
var grid = document.getElementById('<%= GridviewName.ClientID %>');
var FooterTextBoxName = grid.getElementsbyTagName('FooterTextBoxName');

Get edit item value in RadGrid client-side

i'm looking for somone that can help me on this problem:
i've a Telerik RadGrid in edit-mode, after pressing radgrid's update button i do some checks into a javascript file; i want to check the value in some cells that are in edit mode but i don't know how to see the value.
I try to explain better with an example: i have some columns editable and some read-only, for the read-only columns i can view the value but for the editable columns i view all the html of the cell and i don't know how to get only the value, here is the code
function calculate(dgRDO) {
var grid = $find(dgRDO).get_masterTableView();
var righe = grid.get_editItems();
for (var i = 0; i < righe.length; i++) {
var row = righe[i];
//i can view this value, CODART column is ReadOnly
var codart = grid.getCellByColumnUniqueName(row, "CODART").innerHTML;
//i cannot view only the value but i view the entire html of the cell, PREZZO column is editable
var prezzo = grid.getCellByColumnUniqueName(row, "PREZZO").innerHTML;
}
Thanks for any suggestion

RESPONSE FROM TELERIK (IT WORKS)
In order to easily access RadGrid cells client-side you could use the ClientDataKeyNames property. It should contain the DataField names of the columns that will be accessed on the client. Illustration on extracting key values client-side is available in this article.
A sample function for accessing a column that is added to the ClientDataKeyNames collection would look similar to this:
function command(sender, eventArgs) {
var grid = $find("<%= RadGrid1.ClientID %>");
var masterTableView = grid.get_masterTableView();
var editItem = masterTableView.get_editItems()[0];
var cellValue = editItem.getDataKeyValue("Quantity");
}

Try this
var prezzo = grid.getCellByColumnUniqueName(row, "PREZZO").val();

passing dynamically created ASP.NET controls to Javascript

I'm dynamically generating a textbox and a dropdownlist in my ASP.NET web app table row, I want to change value of textbox based on dropdownlist selectedindex using javascript, but I don't know how to pass these dynamically created controls to my Javascript function.
TextBox t = new TextBox();
tc.Controls.Add(t);
tr.Cells.Add(tc);
tc = new TableCell();
DropDownList ddl = new DropDownList();
ddl.Attributes.Add("onChange", "return OnFoodChange(this," + t + ");");
tc.Controls.Add(ddl);
I pass 'this' instead of my combobox, and it works fine, but textbox is not detected in my following javascript function:
function OnFoodChange(myCmb,myTxt) {
try{
var q = document.getElementById('<%= HFFoodPrice.ClientID %>').value.toString();
var q2 = q.split(';');
alert(myCmb.selectedIndex.toString());
alert(document.getElementById(myTxt.value));
for (var j = 0; j < q2.length; j++) {
if (q2[j] != '') {
var q3 = q2[j].split(',');
{
}
}
}
}
catch(err)
{
alert(err.message);
}
}
what is the correct way of passing dynamically created controls to a javascript function? should I set controls ID in my codebehind?

In C#:
ddl.Attributes.Add("onChange", "return OnFoodChange(this," + t.ClientID + ");");
in Javascript, try this:
alert(document.getElementById(myTxt).value);

Fill Array with div elements populated dynamically in codebehind. C#, javascript

I have a report populated as a table with a stringbuilder from the codebehind. The first TD of every row is a checkbox, the id of each checkbox is assigned dynamically:
sb.Append("<td><input type='checkbox' id='chkSelectAll_" + i + "' name='chk_" + i + "' onclick='JavaScript: chkAll_click(this);' /> </td>"
The aspx page uses a master page and
<asp:Content><div id='divMain'></div></asp:Content>
format other than a form to populate. The problem I am running in to is that I am having trouble finding all the elements (or any actually) of the div to work with. Here is the javascript I have been given. (Team project at work, I was just assigned 1 task on the project so changing anything is not an option.)
function divBatchBuild_click() {
debugger
var form = document.forms[0];
var visitList = '';
for (i = 0; i < form.elements.length; i++) {
if (form.elements[i].type == 'checkbox') {
//alert(form.elements[i].id.toString());
if (form.elements[i].checked == true &&
form.elements[i].id != 'chkSelectAll') {
var y = form.elements[i].id;
//alert('id=' + y[1].toString());
visitList = visitList + y[i].toString() + '|';
}
}
}
}
Apparently this worked on a previous project, but when used with this report the process never goes inside the if statement. Any help on what is going wrong is appreciated.

I think you want to first get the div, then get the elements in the div with the checkbox tagname. Something like:
var div = document.getElementById('divMain');
var elements = div.getElementsByTagName('checkbox');
for (i = 0; i < elements.length; i++) {
