textbox focus problem

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net

I have a textbox (txtMaiden) and a radio button list (rblGender) in two separate User Controls that I'm using for a registration site. The txtMaiden control appears or disappears depending on whether Male or Female is designated on the radio button. This all works fine but I want the textbox to have focus when it becomes visible. As of now, it only gets focus when the page refreshes. Code follows. Any ideas?

<Prf:gender ID="GenderE" Gender='<%#Bind("Gender")%>' runat="server" />
<Prf:maiden ID="MaidenE" Maiden='<%#Bind("MaidenName")%>' Maiden_Disp='<%#Bind("MaidenName_Disp")%>'
    runat="server" />

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="gender.ascx.vb" Inherits="userControls_profile_gender" %>
<asp:Panel ID="pnlGender" Visible="true" runat="server">
    <div class="label">
        <asp:Label ID="lblGender" Text="Sex:" runat="server" />
    <div class="ctrl">
                <asp:RadioButtonList ID="rblGender" AppendDataBoundItems="True" AutoPostBack="True"

Excel-like experience - gridview focus problem



I'm creating a page where people can order several items from a list without having to press "edit" and "save" in between like you normally would in a gridview. The user writes down the quantity, and finally presses a "submit" button that saves the order.

I want the user to have a windows form (or excel) like eperience, so once the user puts in the quantity and moves on to the next item, either by TAB or by clicking on the TextBox, i make some calculations without the user beeing bothered with a full refresh or having to press a buton to execute the event, so I place the controls inside an UpdatePanel and use TextBox.TextChanged. The event runs code that calculates the sum for the row (price * quantity) and shows that in a column called "Sum", and updates a label in a fixed position with the new order total ("Total").

Any ideas on how to achieve this?

Right now I use a GridView with a templatefield for the Quantity and set the TextBox.TextChanged event to fire to make the calculations. The problem is that the focus then changes.

By using SmartNavigation or the ScriptManager.SetFocus I manage to retain focus on the TextBox that executed the Postback, but the user might have moved on to a textbox far down the gridview (thus causing the postback by leaving the previo

Problem with JavaScript on Textbox

 I have a textbox which is populated by an external javascript file which I cannot alter without affecting another part of the system. What I would like to do is once this textbox has a value to do something with it. The javascript that I want to use is fine, but it won't automatically when a value has populated it i.e. onchange. It will work when the event is onfocus. Is there away in which I can automatically fire off my javascript event when a value has entered the textbox from another piece of javascript code?

Problem with overriding OnPaint method of System.Windows.Forms.Textbox

Hi,   I want to change the border colour of the Textbox. However, when I override the OnPaint method, some strange behaviour occurs.   The new border is drawn, as is the textbox background. However, the text itself appears in bold and only while I actually type something in, afterwards it disappears. I have provided a sample of my code here:         protected override void OnPaint(PaintEventArgs e)         {             base.OnPaint(e);             Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);             ControlPaint.DrawBorder(e.Graphics, rect, _BorderColour, ButtonBorderStyle.Solid);         }   I have also set the style of the control to Userpaint, so that the paint method is actually used. Does anybody know how to solve this issue?

Textbox WebControl Enabled/Disabled problem: Disabled controls looks great in Firefox but in IE they


Hi everyone,

I don't know if you face the same problem when your page logic has to set the enabled textbox's property to FALSE.  If i use FireFox to browse the page, my disbled controls are show with a dark-silver background color (perfect for me), but when i browse with IE, disabled or enabled textboxes are show the same way (no color differences).

Is there a way to manage controls appearance depending on the Enabled property?

I appreciate your support.
