I have following Rad controls on a user control. I load this user control dynamically. I am doing everything mentioned in general to maintain viewsatate.

Following RadText box is not maintaining a viewstate in between postbacks. Next to Rad I have put regular aspText box and it works fine with viewstate.

<telerik:RadTextBox ID="txtName" runat="server" MaxLength="50"

meta:resourcekey="txtName" Width="300px" EnableViewState="true">

</telerik:RadTextBox>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> --- This one works fine

Following Rad combobox is behaving like locked I can not select values from a dropdown. But next to this one is regular aspdropdown on the same page which works fine with view state as well as with dropdown list selection. Exactly same code I use to load both boxes. Which is also given

<telerik:RadComboBox ID="cboAccount" runat="server" Skin="Vista"

meta:resourcekey="cboAccount" Sort="Ascending" Width="300px" AppendDataBoundItems="True">

</telerik:RadComboBox>

<asp:DropDownList ID="DropDownList1" runat="server">

</asp:DropDownList>

With cboAccount

.DataSource = _piggyBankEligibleAccounts

.DataTextField = "Text"

.DataValueField = "id"

.DataBind()

End With

With DropDownList1

.DataSource = _piggyBankEligibleAccounts

.DataTextField = "Text"

.DataValueField = "id"

.DataBind()

End With

Hello A K,

I followed your description in the attached sample however I was unable to replicate the issue. Can you check it out and let me know what differs in your case?

Thank you for replying Lana!

I have a user control called piggybank on the control there are few controls outside the panel and some are on the panel. On page load of user control I populate all these controls. On parent page I have radpanel bar control. On the page load of parent page I dynamically add panel items ( depending on the count of accounts) with this piggy bank user control. Piggy bank user control has edit button. By default panel on user control is invisible. When user clicks edit I make panel visible. It does make the panel visible but Data on the textboxes and other control is gone. But by default if I keep this panel visible, I do see the data on these controls. In between postbacks if panel is invisible by default viewstate is not maintained. None of the comboboxes on this page works.

If you need any additional information please let me know.

Thanks you!!!
