ASP:Login : Password not autocomplete after enter Username

I used ASP:Login to take a Login form for my page.
Now I have 2 problem and I try to find a solution but ... #_#.
Now, I enter to login page. Type user, type password, then Enter
Problem 1 : Enter key not focus to Login button. It's mean, I must click to Login button to login. How can to set default button in this case ?
Problem 2 : Ok. Logged in. The browser (Chrome, Firefox ...) ask to save password. Ok. Saved.
And then, when I enter to login page in another time. The password will not autofill when I enter the username (browser still save username and password info).
Did I take a mistake in my setting or my code ? :(
My code :

Solution for Problem 1 is to use Asp.Net panel and use it's Defauenter code hereltButton property.
For example,
<asp:Login ID="Login1" runat="server">
<LayoutTemplate>
<asp:Panel ID="Panel1" runat="server" DefaultButton = "LoginButton">
<table cellpadding="4" cellspacing="0" style="border-collapse:collapse;">

In regards to problem 2, I do not know why your browser is not pushing password back to the text box.

TextBox in the RadGrid control doesn't make partial postback and fills the other controls

I have a TextBox (named as txt_lect_in) in RadGrid and I handled the TextBox changed event so it fills other textboxes (gv_txt_name,gv_txt_mobile,gv_txt_address,gv_txt_email) in the same grid.
The problem is:
The TextBox (txt_lect_in) doesn't fills the other textboxes, I know the reason but I don't know how to fix it.
After I remove the RadAjaxManager, it fills the other textboxes in the grid but it does full post back, how to keep the ajax manager and fill the controls at the same time?

child grid SelectionChanged event does not fire in DevExpress

I have 2 ASPxGridView controls
- gvPatient and
- gvOrder
gvOrder is placed inside detail row template of gvPatient.
the issue i am faciing is i have to get the values of rows of gvOrder(child) on focus row changed or selection changed. I have code for these events but these events do not fire on selection changed of rows and focus changed of child grid . Strange this- here these child grid events fire on gvPatient(parent) row selection and focus changed.

You need to set properties SettingsBehavior.ProcessSelectionChangedOnServer and
SettingsBehavior.ProcessFocusedRowChangedOnServer to true.
From docs: "If the ProcessSelectionChangedOnServer property is set to false, the ASPxClientGridView.SelectionChanged event is handled on the client side without a postback to the server".

Why you are attaching the events in the code behind?
Try change this line:
<asp:LinkButton ID="lnkDeleteCart" CssClass="deletebutton" runat="server"><%=GetGlobalResourceObject("lang", "Delete")%></asp:LinkButton>
To this:
<asp:LinkButton ID="lnkDeleteCart" CssClass="deletebutton" runat="server" OnClick="lnkDelete_Click"><%=GetGlobalResourceObject("lang", "Delete")%></asp:LinkButton>
And comment these lines on your code-behind:
EventHandler handler = new EventHandler(this.lnkDelete_Click);
if (this.lnkDelete != null)
{
this.lnkDelete.Click -= handler;
}
if (this.lnkDelete != null)
{
this.lnkDelete.Click += handler;
}
I made the change only on the delete button, you probably need to change others too ...

If you want your modal popup to be displayed when the user clicks on the btn_Add_Task button, you should set that button as the TargetControlID of the extender:
<cc1:ModalPopupExtender ID="btn_Add_Task_ModalPopupExtender" runat="server"
TargetControlID="btn_Add_Task" PopupControlID="pnl_Add_Task"
BackgroundCssClass="modalBackground" DropShadow="True" />
In your current code, the modal popup is triggered by a button named Dummy_btn, which I can't find in your markup, but which probably isn't what you want.

We had many issues with ajax popup. you might want to try the approach we have been using for past one month or so with out any issues. This approach creates a popup with out need of ajax / jquery / javascript /css/ update panel .
here:
A modal popup with out using ajax, update panel, jquery or javascript- surprisingly this seems to work
