Evaluate Checkboxes entered at Runtime

Michael Haberfellner · Mar 5, 2007

hi folks,

i do have the following problem (that nearly drives me nuts

1. within body-tags i call a void <% void_buildlist("lstService"); %>
2. this void connects to a database and creates code for a selfmade-grid
3. this is posted in the void by response.write and put on the website

up to here everything works fine!

now i added a checkbox for each gridline by adding this code to the text
created in the void in front of each gridline:

<input id=\"chkTimeDisplay" + varReader + "\" class=\"checkboxStd\"
type=\"checkbox\" name=\"chkTimeDisplay" + varReader + "\" />

4. this creates perfect checkboxes named chkTimeDisplay[+index] in every
gridline

works fine too!

5. but now i want to evaluate all checkboxes, using for example

foreach (Control locCtrl in this.Controls)
{
lblchecker.Text += locCtrl.FindControl + "; ";
if (locCtrl is CheckBox)
{
....do something
}
}

and here is the problem: no result! even if i use findcontrol with the
one correct checkboxname from the pagesource, there is no result

the controls can't be found. is it because they were produced during
runtime?

can anybody help me out?

thanx and nice greetings from vienna/austria

if you create html controls, the page will know nothing about them. you
should create controls or use the Request.Form collection to get values.

hi again,

sorry for not clearly writing what i really need

if i have the following in the aspx file

<body>
...
<asp:CheckBox ID="chkMe_One" runat=server/><br />
<% void_write_checkbox(); %>
...
</body>

and in the aspx.cs file

public void_write_checkbox()
{
Response.Write("<asp:CheckBox ID=\"chkMe_Two\" runat=server/>");
}

the second checkbox is not appearing.

the problem is, i need to put it onto the page via response.write()

can anybody help me please?

big thanx

mike
