You may not know that. Net2.0 Tips

1. After the page is submitted, keep the scroll bar position

You can add a maintainscrollpositiononpostback directive to the page instruction.

The following are the referenced contents: <%@ Page language= "C #" maintainscrollpositiononpostback= "true" autoeventwireup= "true" codefile= "..." Inherits= "..."%>

2. After the page is loaded, move the focus to a control, just specify the form's DefaultFocus property.

The following are the referenced contents: <form id= "frm" defaultfocus= "txtUserName" runat= "Server" > ... </form>

3. Set the default corresponding button for the form through the DefaultButton property, that is, the button that fires when the user knocks in the carriage

The following are the referenced contents: <form id= "frm" defaultbutton= "btnsubmit" runat= "Server" > ... </form>

4. You can use the $ symbol to easily find a control using the FindControl method

The following are the referenced contents: <form id= "Form1" runat= "Server" defaultfocus= "Formvw$txtname" > <div> <asp:formview id= "FORMVW" runat= "Server" > <ItemTemplate> Name: <asp:textbox id= "txtname" runat= "Server" text= ' <%# eval ("FirstName") + "" + eval ("LastName")%> '/> </ItemTemplate> </asp:FormView> </div> </form>

In the example above, use the DefaultFocus property of the form to specify the control in which the focus of the page is loaded, using the $ symbol to easily locate the Txtname

You can also use the following code to easily find the control

The following are the referenced contents: TextBox TB = this. FindControl ("Form1$formvw$txtname") as TextBox; if (TB!= null) { Access TextBox Control }
