position = dttableDetails.Columns[strColumnName].Ordinal;
if (strtype.Contains("CheckBox"))
{
try

GrdDynamicControls.Rows[i].Cells.RemoveAt(position);
chkCheckBox.ID = strControlName;
chkCheckBox.AutoPostBack = true;
tcCheckCell.Controls.Add(chkCheckBox);

View 4 Replieshow to place controls on top of one another in html.
For example. I am trying to place 2 labels on top of eachother. and also I am trying to place a text box under a dropdownList.
I have an imagebox that is on a masterpage. What I want to do is place a label on top of that imagebox. I have that part working, but when I resize my window, the label stays the same size and eventually covers the imagebox. How would I make the image box stay the in the same area of the imagebox no matter what size the window is? Here is a sample of the code I am using now.

I have an ASP.NET web app that retrieves a JSON collection and outputs the content of the collection, via LINQ to a StringBuilder that has a lot of table and other tags in HTML, with my data pieces interspersed.
This is what I mean:
sb.AppendFormat(@"
<table cellpadding=""0"" class=""TableStyle"" style=""width: 70%; height: 100%;"" cellspacing=""5"">
<tr>
<td class=""PicHolder"" style=""width: 151px"" rowspan=""2"">
<a href=""http://twitter.com/{0}"" target=""_blank""><img height=""45px"" width=""45px""
[Code]....
count.First.userName, count.First.imgURL, newdata, count.Count, count.First.userName, count.First.txtDesc, (title != string.Empty) ? title2 : newdata, metaDesc2);
You can see all of the {0} and {1} data place holders I am using in the code above, and the reference to the data required at the end of the StringBuilder method call.
I want to be able to separate the HTML from my app so that I can edit it more easily without having to escape all of the "" quote marks.
So I need a template that has place holder for where my data goes. This is a noob question and I know exactly what want but not how to implement it.
This page is a directory search, it has controls identified by record ID, however there exists a situation where there can be more than one result with the same record ID, thus making .NET barf. I had originally implemented a check that just didn't put the control on the page, if it was already there, but we've been getting negative feedback.
My question is this: Is there a way to put the same control in two places at once, for instance having if a user checks one, the corresponding one checks as well? I'm not terribly well versed in how .NET behaves, but I'll try to provide as much additional context as possible, if needed.
EDIT: Here's the updated code that generates the controls by looping over a datatable of results
Dim cbxSendInfo As CheckBox
Dim strCheckboxID As String = "cbxSendInfo-" & drOrganizer("ID") & "-" & i
Debug.text = Debug.text & " Loading Checkbox (" & strCheckboxID & ")...<br />"
cbxSendInfo = New CheckBox
cbxSendInfo.ID = strCheckboxID
cbxSendInfo.enableViewState = true
And here's the code that finds the controls and builds the contact list:
Dim strCheckboxID As String = "cbxSendInfo-" & drOrganizer("ID") & "-" & i
Dim cbxSendInfo As CheckBox = Me.tblResults.FindControl(strCheckboxID)
If cbxSendInfo.Checked Then
alOrganizers.Add(drOrganizer("ID"))
End If
Where drOrganizer("ID") is the record ID, and i is the result record number.
I know this is a terrible way to do this, at least from my background, but like I said, this is inherited code that's been hacked to pieces.
the developer who wrote this code is no longer with us and there are absolutely no comments whatsoever for us to know whats happening. Me and my other co-worker are just learning .net and hence not that much experts. can some one please tell us what the code does in both the files below and how they are related to each other ( we are very +VE that they both are related) first file. its called products.aspx. the code is below
