Scroll position not well maintained after ajax call

I have some cascading comboboxes. No matter where I am when I start, when I select the first and the other is updated, the 1st keeps focus, but the page scrolls up so that the 1st control is at the very bottom of the browser window. What can I do to change this?

<table>

<tr>

<td>

<asp:Label ID="lblPosition" runat="server" CssClass="Label"></asp:Label>

</td>

<td>

<CW:ComboBox ID="rcbPosition" DataTextField="PosName" DataValueField="PosNum" Width="204px"

runat="server" OnSelectedIndexChanged="rcbPosition_SelectedIndexChanged" AutoPostBack="true"

CausesValidation="false" AppendDataBoundItems="true" OnClientSelectedIndexChanged="SelectSaveChangesToAllSessions">

<Items>

<Telerik:RadComboBoxItem Text="<%$Resources:LanguageResource, AllPositions%>" Value="0" />

</Items>

Rendering of RadAutoCompleteBox

The autocomplete box is rendered in a div element, other controls just in a span. If I assign a label to a Telerik control, the control is placed right of the label, but the auto complete box is placed underneath (as it's a div, not just a span).

Can I somehow change that behavior?

how to close RadGrid's EditForm?

On my radgrid, I have EditFormSettings EditFormType set to WebUserControl. Inside that WebuserControl, I have a submit button and a delete button. And I know that you can close these by setting the CommandName to Update or Cancel. However, this is not working when I have the another control nested inside that control.

Can I close these windows explicitly either through js or the codebehind? I'm not sure but I think my problem is that I have a control nested inside another control. Both have the commandnames set to Update and Cancel. There must be some conflict?

Thanks in advance.

Getting values from textbox in item template

In the ListBox ItemTemplate Demo, a numeric textbox is included to allow users to enter order Quantity. No problem creating a similar item template. No problem passing item.Value to SqlParameter and inserting to database. But I cannot figure out how to grab a value from a textbox and pass that as another parameter.

Code below passed an empty string or NULL to @Quantity:

foreach (RadListBoxItem item in collection)
{
    cmd4.Parameters.Clear();
   cmd4.Parameters.AddWithValue("@Product_ID", item.Value);
cmd4.Parameters.AddWithValue("@Quantity", Convert.ToInt32(item.FindControl("RadNumericTextBox1.Text") as TextBox));
   cmd4.ExecuteNonQuery();
}

A few articles I found suggest textbox values are lost during postback? Anyone else run into this problem? Advice appreciated.

RadDatePicker ReadOnly

1. How do I set RadDatePicker to ReadOnly mode so that it prints better (Enabled = False prints light).
2. How do I hide the calendar icon in ReadOnly mode? RadComboBox has .ShowToggleImage = False but not RadDatePicker.

Radconfirm doesn't get the focus

Hi, I have a problem with radconfirm dialog. I open the dialog from C# code by:



ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirmQuantity", "confirmQuantityCorrection();", true);

My function is very simple in javascript:

function confirmQuantityCorrection(){

var oConfirm = radconfirm('Are you sure', confirmCallBackQuantity, 280, 150, null, 'Confirm');

return false;

}

It works fine, but I noticed that I have no focus in confirmation dialog so it is not possible to use only keyboard for confirmation. Focus remains in the main window. I find this post , but it doesn't work and I cannot get the focus.

It looks other people has the similar problem with window opening, but the solution doesn't work for dialog.
Do you have similar problems? Did you find any solution for it?

Thanks a lot,
Petr

Can I get lat/lon with address?

I assume if I need to get the lat/lon from a given address I need to use another service for this right? I need to place a marker with the given address. I was just checking here anyways.

Thanks,
