Find Dynamically Created Table in RadWindow

I have some code that works fine in an aspx page but I would like to use it in a radwindow.
On the page I have numerous input controls but one of the things is a table that has a button that allowas the user to add another row of inputs. When they hit the button it creates another row in the dynamically created table, but since the rows are created each time I need to reload the old data into the past rows.

private void SetPreviousAccountData(int rowsCount)

{

if (Page.IsPostBack)

{

Table table = (Table)Page.FindControl("Table1");

if (table != null)

{

for (int i = 0; i < rowsCount; i++)

{

//Extracting the Dynamic Controls from the Table

DropDownList ddAccount = (DropDownList)table.Rows[i].Cells[1].FindControl("ddAccount" + i + "Col_1");

//Use Request objects for getting the previous data of the dynamic textbox

ddAccount.Text = Request.Form["ddAccount" + i + "Col_1"];

TextBox txtProxy = (TextBox)table.Rows[i].Cells[3].FindControl("txtProxy" + i + "Col_3");

//Use Request objects for getting the previous data of the dynamic textbox

txtProxy.Text = Request.Form["txtProxy" + i + "Col_3"];

}

private void AddAccount(int rowsCount, bool addNewRow)

{

//Sore the current Rows Count in ViewState

if (addNewRow)

{

rowsCount++;

ViewState["AccountRowCount"] = rowsCount;

}

//Creat the Table and Add it to the Page

Table table = new Table();

table.ID = "Table1";

AccountSpan.Controls.Add(table);

for (int i = 0; i < rowsCount; i++)

{

TableRow tRow = new TableRow();

TableCell lblAccountCell = new TableCell();

TableCell tcAccountCell = new TableCell();

TableCell lblProxyCell = new TableCell();

TableCell tcProxyCell = new TableCell();

DropDownList ddAccount = new DropDownList();

TextBox txtProxy = new TextBox();

lblAccountCell.Text = "Account Number:";

lblProxyCell.Text = "Proxy:";

ddAccount.ID = "ddAccount" + i + "Col_1";

txtProxy.ID = "txtProxy" + i + "Col_3";

if (ddClientID.SelectedIndex > 0)

{

ClientDataContext db = new ClientDataContext();

var query = from p in db.ProxyAccounts

where p.ClientID == Int32.Parse(ddClientID.SelectedValue)

select new

{

p.ProxyAccountID,

Account = p.NameOnAccount + ": " + p.AccountNumber

};

ddAccount.DataSource = query.ToList();

ddAccount.DataTextField = "Account";

ddAccount.DataValueField = "ProxyAccountID";

ddAccount.DataBind();

ddAccount.Items.Insert(0, "");

}

tcAccountCell.Controls.Add(ddAccount);

tcProxyCell.Controls.Add(txtProxy);

tRow.Cells.Add(lblAccountCell);

tRow.Cells.Add(tcAccountCell);

tRow.Cells.Add(lblProxyCell);

tRow.Cells.Add(tcProxyCell);

table.Rows.Add(tRow);

}

SetPreviousAccountData(rowsCount);

}

The problem is the line

Table table = (Table)Page.FindControl("Table1");  does not find the table.

I guess if I could find a way to simply just add a new row to the table on the button push this issue would be solved but have not be able to figure that out yet.

CheckBox Columns in RadGrid

Dear Telerik development team,

is there any way to create CheckBox columns in RadGrid fully programmatically in the code-behind?

I have List<string> collection and I would like to add RadGrid (with two columns) to my aspx page. However, I must do this fully programmatically by code-behind. Please, do not ask me why such scenario ;) .
So, the first column should contain items from List<string> collection, and the second one should contain enabled checkboxes.
Finally, a RadButton to get which items from the RadGrid rows are selected, should be added under the RadGrid.

Can somebody help me to accomplish described scenario by code-behind only, please?
Thank you very much.

Miro
