Unfortunately, there's still a bit of a problem under ASP.NET 2.0. I took the VB.NET example code that on the web site where you also download the control. I placed the code under a directory called "test" under my web site. When viewing the page "HierarGridDemo.aspx" (http://localhost/test/HierarGridDemoVB/HierarGridDemo.aspx) everything works until you do a postback. On a postback you get the error "UserControl could not be loaded: test_authors.ascx ". It looks like ASP.NET 2.0 is still pre-pending the first directory off the server root to the control name. What is the purpose in doing that?

Denis,

First of all, LOVE THE CONTROL!!! I've been a big fan of it and am happy to hear that you have posted a version (2) for ASP 2.0. So, here's my rant...

I copied the DLL over, tested my code, and now, on the first item in my hiergrid, if I click the plus sign, it gives a javascript error. Also, if there is just one item in the grid it gives the same error. But, other items in the list work fine. Any suggestions?

I've noticed that DynamicControlsPlaceholder doesn't work, if the path of user control has '.', e.g. DesktopModules\FSVK.SearchResults.
I fixed it by adding the following line in RestoreChildStructure method after typeNameGarbage assignment:

typeNameGarbage = typeNameGarbage.Replace('.', '_');//if subdir has '.' in the name, it also should be replaced with '_'

But it's likely that other special characters should be replaced with '_' as well.

I've noticed, that your blog shows e-mail addresses in clear text. It's not good for spam prevention.

Hi Michael,

thanks for pointing out. I'll fix that in version 2.1.

Hi

Is there a way to solve the following scenario with your control:

I dynamically create a table which contains text and radioboxes in the table cells. There is an autopostback at the radioboxes.
After the table is generated I add it to a placeholder.

Anyway, I would like to use your dynamic placeholder.
Just replacing the regular placeholder with DCP, causes the DCP_ControlRestored to trigger on only the table (not the radioboxes that I would like).

I understand that I need to add each of the radioboxes to the DCP, but how can I do that when I also need to add and place the radioboxes to tablecells?

Thanks!

I hope you enjoyed my beautiful sunny country!

Hi,

I am using you control, its really great, but I am geting the following error, when I uploded to production server. Can any one please point out, what wrong.

Could not load UserControl '/plugins/Playbill/admin/Templates/plugins_playbill_admin_templates_t_questions.ascx' from VRoot '/' with PersistenceString: System.String[]. Found 0 files that match the pattern e:\inetpub\svc026\plugins\Playbill\admin\Templates\plugins*playbill*admin*templates*t*questions.ascx


Thank you very much.

Hi guys. Courage is the art of being the only one who knows you're scared to death.
I am from Sudan and also am speaking English, tell me right I wrote the following sentence: "Tips when selecting an seo - always check testimonials.” last year, but the truth is that of the seo market is made up of snake oil."

Thanks :-D. Ellema.

Hi Denis Bauer,

First of all thanks a lot for great functionality of getting dynamically added controls and their values.
I am using this functionality in one of my application. It is very useful. I got a little problem. I am
dynamically adding textbox, dropdown list, checkbox list etc.. in placeholder. I can get all these
controls and their values if I added these controls directly in Placeholder. But if I add dropdown list
(or any control) in Table cell inside Table Row inside Table, then I cannot get this control’s value from placeholder.

Here is the code

Working Code:
DropDownList ddlSecond = new DropDownList();
ddlSecond.ID = ControlId;
ddlSecond.Items.Add("--Select Item--");
if (itemList != "")
{
string[] items = itemList.Split(',');
for (int j = 0; j < items.Length; j++)
{
ddlSecond.Items.Add(new ListItem(items[j], items[j]));
}
}
Placeholder1.Controls.Add(ddlSecond);
________________________________________________________________________
Not Working Code:
Table tbl = new Table();
TableRow tr = new TableRow();
tr.Height = (Unit)30;
tr.ID = "tr" + ControlId;

TableCell tcSecond = new TableCell();
tcSecond.ID = "tc" + ControlId;
DropDownList ddlSecond = new DropDownList();
ddlSecond.ID = ControlId;
ddlSecond.Attributes.Add("runat", "server");

tcSecond.Controls.Add(ddlSecond);
tr.Cells.Add(tcSecond);

ddlSecond.Items.Add("--Select Item--");
if (itemList != "")
{
string[] items = itemList.Split(',');
for (int j = 0; j < items.Length; j++)
{
ddlSecond.Items.Add(new ListItem(items[j], items[j]));
}
}
tbl.Control.Add(tr);
PlaceHolder1.Controls.Add(tbl);

If you have any idea of this problem,Please let me know. It is very important and useful for me. Again thanks for this utility.

Thanks and Regards,
Pavan

Hi

The Dynamic control placeholder is really excellent. It saved me allot of time.
