Hi; I am using the released version of AJAX Controls and I am working on a Web Application with a Masterpage. 
What I would like to do is, I have two Radiobuttons and two TextBoxes inside an update panel; When the user clicks the RadioButton1, I would like to set the focus to TextBox1 and if the user clicks the RadioButton2, I would like to set the focus to the TextBox2. I have googled for it and found couple of similar solutions that works with the beta AJAX assembly "Microsoft.Web.Atlas" but it doesn't work with the ASP.Net AJAX which I am using in my current project.

The following code works just fine when I use the Microsoft.Web.Atlas so please let me know if anyone knows a solution that works with the released version of AJAX Controls; Thanks in advance.

//***************************************************************************************

    //Code behind

    protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
    {
        SetMyFocus(ref TextBox1);
        TextBox1.Focus();
    }

    private void SetMyFocus(ref TextBox txtBox)
    {
        string focusString = "setTimeout(\"$('" + txtBox.ClientID + "').focus(); \", 100);";
        ClientScript.RegisterStartupScript(this.GetType(), "focusString", focusString, true);
    }
    protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
    {
        SetMyFocus(ref TextBox2);
        TextBox2.Focus();
    }

 The following code is from the source view of the page

 
<%@ Page Language="C#" MasterPageFile="~/Test.master" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" Title="Untitled Page" %>
<%@ Register Assembly="Microsoft.Web.Atlas" Namespace="Microsoft.Web.UI" TagPrefix="cc1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="CPHTest" Runat="Server">
    
   <cc1:ScriptManager ID="ScriptManager2" runat="server" EnablePartialRendering="true">
   </cc1:ScriptManager>
    <cc1:UpdatePanel ID="UpdatePanel1" runat="server">
      <ContentTemplate>
          <asp:RadioButton ID="RadioButton1" runat="server" AutoPostBack="True" OnCheckedChanged="RadioButton1_CheckedChanged" GroupName="Group1" /><br />
          <asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="True" GroupName="Group1" OnCheckedChanged="RadioButton2_CheckedChanged" /><br />
          <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
          <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
          <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br />

    </cc1:UpdatePanel>
</asp:Content>
 

Hi,

I am using the new SetFocus method of the ScriptManager class.

Example:

ScriptManager1.SetFocus(TextBox2);

I works with the last release of Microsoft AJAX.

Hope this helps,

David

ScriptManager1.SetFocus(TextBox2);

I just have the

ScriptManager1.Focus() method. please help.

Thanks in Advance

Use the latest version of ASP.NET AJAX

Thanks lot

I also having same prob and search the web for solution. This is tha only place that I found a resolution.

Thanks lot again

When using masterPage system, i can't access the "ScriptManager1" object within the codebehind of ContentPage file..

Is there any solution for this ??? 

You access the scriptManager from a content page using the static GetCurrent method:

ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);

Good post,

But I found another issue. The text box I am using is wired up to a  AutoCompleteExtender control. This works fine but as soon as I set focus using the above code this autocomplete does not work anymore.

 Any ideas?

Thanks to all contributor,  Its been three days i have been googling. Finally

Feels good, for a newbie in AJAX

I am using GridView and there is a textbox in that on which i need my focus but this code is not working in my case. where i have to write the ScriptManager1.setfocus() code

please tell me ASAP 

Dim sm As ScriptManager = ScriptManager.GetCurrent(Me)

'Find the textbox in the grid,  I have done for the footer row but you can do row index to get the right row and the control

Dim UserIDTexbox As TextBox = CType(Me.uxGridView.FooterRow.FindControl("UserIDTextBox"), TextBox) 

Hi All,

I need one help from you. I am trying to set focus to different controls after my different PostBack events, but this.ScriptManager1.SetFocus(myControlName.ClientID); is not working.

In my ASPX page I have RAD CONTROLS (RadComboBox and RadCalendar) and also I am using AjaxControlToolkit Controls (ToolkitScriptManager and ModalPopupExtender) also.

In my page, RadComboBox is in UpdatePanel - ContentTemplate area and on its SelectedIndexChanged function I am trying to set focus to another Control using the above code:

this.ScriptManager1.SetFocus(myControlName.ClientID);

but this is not working... Do anyone know any solution for this?

Hi All,

I got solution for the above issue. I was trying to set focus using the code 

this.ScriptManager1.SetFocus(myControlName.ClientID);

and I wrote this code in my SelectedIndexChanged Event Function. That time this code didn't work.

 Now I changed this code to Page Load Function i.e.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
                 this.ScriptManager1.SetFocus(myControlName.ClientID);
        }
        else
        {
                this.ScriptManager1.SetFocus(GetPostBackControl(this.Page).ClientID);
        }
    }

Here I am using a function GetPostBackControl() to identify the current postbacking control and I am setting focus to the same control. If you want to move focus to any other control, just use a Switch Statment.


    public static System.Web.UI.Control GetPostBackControl(System.Web.UI.Page page)
    {
        Control control = null;
        string ctrlname = page.Request.Params["__EVENTTARGET"];
        if (ctrlname != null && ctrlname != String.Empty)
        {
            control = page.FindControl(ctrlname);
        }
        // if __EVENTTARGET is null, the control is a button type and we need to
        // iterate over the form collection to find it
        else
        {
            string ctrlStr = String.Empty;
            Control c = null;
            foreach (string ctl in page.Request.Form)
            {
                // handle ImageButton controls ...
                if (ctl.EndsWith(".x") || ctl.EndsWith(".y"))
                {
                    ctrlStr = ctl.Substring(0, ctl.Length - 2);
                    c = page.FindControl(ctrlStr);
                }
                else
                {
                    c = page.FindControl(ctl);
                }
                if (c is System.Web.UI.WebControls.Button ||
                         c is System.Web.UI.WebControls.ImageButton)
                {
                    control = c;
                    break;
                }
            }
        }
        return control;
    }

Thank you,
