AJAX :: Setting Focus On 2.psotback With Ajax And Usercontrols?
Aug 13, 2010
I have a problem setting focus on a usercontrol in asp.
I have a masterpage with a script manager and a few contentpages. On two of the contentpages I have a usercontrol. Inside this control I have a updatepanel that has another usercontrol that has a asp:textbox, aka TheTextBox. I need those pages to set the focus to TheTextBox.
The innermost usercontrol sets focus in page_prerender: ScriptManager.GetCurrent(Page).SetFocus(TheTextBox);
Now this works on the first pageload, and the second. But not on the third load! And i cant really understad why, but I'm guessing that its because the 2nd postback is renderd inside an updatepanel and somehow that cause the setfocus to not trigger propperly after the 2nd postback.

I have wierd situation on my side. I have a page that uses a user control driven by ajax. When I enter a code in txtbox. Corresponding questions for that code are brought into the middle section of page basically in user control. I have requirement of setting the focus on the controls so that I can tabout the field with feel of questions being a part of same page.
I have to manually set the focus for the first question and after going thru all the questions I get control lost. Basically it dont come back to the actual page. I have tried to manually put the focus on the button but I couldnt.

I used Ajax collapsible extenders (1 to 9) with formviews in each of them on a web form.
They are all collapsed by default. If the user enters data in collapsible 5 formview and submits data, the page refreshes back to the top of the page (where the collapsible 1 is positioned). I would like the focus to stay in the region the user is working (even after insert/submit operations). How can I do this.

I have figured out a method for displaying a modal popup using the ACT ModalPopupExtender from the server side.This is really important because there is a fair amount of server side initialization that I require prior to showing the dialog.
Basically, I assign a dummybutton as the TargetControlID. Then I define a link button such that when clicked it fires an OnClick event. The handler then does whatever initialization is necessary and uses the show() method of the ModalPopupExtender. This is not rocket science. However, what appears to be rocket science is getting a control within the MPE to get the cursor focus. The problem as I see it is that because I am manually showing the dialog, the JS add_shown function never fires. Of course the add_shown function is attached through JS by using the behavior ID of the MPE. It appears to be the standard way to set focus within a MPE dialog. It appears to only work if the targetcontrolid is a real button that shows the MPE dialog when clicked.
Is it possible to set the focus within a MPE dialog when you are programatically showing the dialog and not attaching a real button press event to the MPE Target Control ID? Obviously the Page.SetFocus or Control.Focus() do not work either before or after the modal dialog is shown:
protected void SignIn_Click(object sender, EventArgs e)
{
Session["InTimeOut"] = true;
Session["logintries"] = 0;
SI_user_login_id.Focus(); /// ---> This does not set the focus either before or after the show method
this.ModalSignOn.Show();
}

I'm having a bit of an issue in my ASP.Net application moving focus from a textbox in one user control to a text box in the next user control on the page after postback. I've searched high and low over the last several days to find a solution but, for whatever reason, have been unable to do so.
I have a page that has user controls loaded dynamically to allow a user to enter data.The number and type of user controls loaded to the page is determined at run time based on a database query.It is possible than many controls of the same type can be loaded. Each user control has its own update panel. Within the update panel of each control is a regular asp panel. Inside of the regular panel there are at least 2 server controls (any other controls that may exist in the user control are not affected by this issue) - a text box and a button.The defaultbutton property of the regular panel is set to the ID of the button within the user control. The desired behavior is to allow the user to enter data into the textbox on one user control hit enter to save the data on that user control the application will set focus to the textbox of the next user control on the page after the data from the "current" user control has been saved. Other considerations;
The application uses master pages. We make extensive use of ajax and the ajaxtoolkit in the application. I am using Visual Studio 2010 and .Net 4 The issue - when first entering the page, one can enter data into the first textbox and press the enter key. Data from "current" user control is correctly saved and focus is correctly moved to the next user control on the page.
Data can be entered into the textbox of "new" user control and when the enter key is pressed, the data is correctly save. The focus appears to move correctly to the next user control on the page.Data cannot be entered into the textbox of the control. Pressing the enter key will not save the data (because none was entered) but the focus will move to the textbox of the next user control on the page.
Data can be entered into the textbox of the user control. When the enter key is pressed, the data is correctly saved and the focus appears to move correctly to the textbox of the next control on the pageBasically, steps 3 and 4 are repeated until the end of the user controls on the page, alternating between being able to enter data and not. Other items of note When one is able to enter data into the textbox of a user control, one can correctly tab through the textboxes of each user control until the end of the page When one is not able to enter data into the textbox of a user control, pressing the tab key will take the focus to the address bar of the browser.
I created a much simplified example of the scenario described above and was able to consistently reproduce the "bad" focus behavior. All of the ajax toolkit controls and code where stripped out of the sample to rule the toolkit out as a cause. The behavior still occurs without the toolkit.
I am including the code for default.aspx and WebUserControl1.ascx.

I have some user controls where I would like to add some javascript that uses Ajax and Jquery technology. Also these scripts should use Sys.WebForms.PageRequestManager.getInstance().add_endRequestand other functions of the Ajax framework.In the past I have added the related code to the hosting aspx page but it becomes a problem when re-using the same control in multiple aspx.

I have usercontrol (called A) and update panel in it
Following are the control in my updatepanel
1. gridview with link button
2. DIV outside the gridview to load the usercontrol (B) from c#
when i hit the link button of gridview i am loading my usercontrol(B) dynamically from code behind and adding it to the DIV which is working fine. I have button inside the the usercontrol (B) and if i hit the button it doesn't trigger the action.
Not sure why it doesn't trigger the click event. i googled and tried enabling ChildrenAsTriggers="true" though it didn't work.
Test.ascx :
<asp:UpdatePanel ID="upList" runat="server" ChildrenAsTriggers="true" >
<ContentTemplate>
<asp:GridView ID="gvList" AutoGenerateColumns="false" runat="server" Visible="true" Width="95%"
OnRowDataBound="gvList" DataKeyNames="Id" GridLines="None"
ShowFooter="false">

On Template_Click event i am loading the user control from code behind and adding it to the div[divContainer]
I tried to investigate in deeper and found that the update panel causing the issue. If i use the below code[rfered one of your article] on the page load event then it works fine. the button triggers it's action. but when i click the button which is in gridview, it should not post back as it is in update panel, but it postback.
private void RegisterPostBackControl()
{
foreach (GridViewRow row in gvList.Rows)
{
LinkButton lnkFull = row.FindControl("Template") as LinkButton;
ScriptManager.GetCurrent(this.Page).RegisterPostBackControl(lnkFull);

I have built a "portal" that displays "widgets" (server side usercontrols). The page contains two columns, each containing an updatepanel. Each widget contains an updatepanel and multiview with the default view showing a "loading" message and the second view contains the actual content.
When a user logs in, I query the database to get a list of widgets the user has access to, along with their column and order number. During page init, I add all of the widgets to the page's columns in the order indicated. Once the page loads, a timer on each widget gets fired and the widget's multiview switches from the "loading" view to the content view and sets the content's visibility to true. This forces the content to load.
Setting up the load this way makes the page load appear faster because it doesn't process any of the widget data until after the initial page load. This all works fine but I have an issue with the order in which the widgets get loaded.
Currently, the page loads and the widgets will start loading from the top of the left column down to the bottom, then it will start loading the top of the right column. The page could potentially have many widgets so I end up staring at a bunch of loading messages on the right side while I wait for the full left column to load. I would really like to be able to load top down across both columns instead of the whole left column and then the right column. For example, load the first widget in the left column, then the first in the right, and so on. This way, the user would have something to look at the top instead of staring at a bunch of loading messages and having to scroll down the page while it loads.

I have the following problem: I have a web form which contains ajax accordion. Each accordion pane contains a usercontrol. Each usercontrol consists of several textboxes and 2 buttons. All the textboxes and 2 buttons (inside these usercontrols) are wrapped in the UpdatePanel. Following updatepanels is the UpdatePanelAnimationExtender for some animation whithin each usercontrol. Each UpdatePanelAnimationExtender has a different animation id from other usercontrols.
Basically when i only put one usercontrol in the accordion pane everythign works. I have my javascript to clear textboxes and the submit button does a postback to server. However, when i put 2 of these controls in 2 different panes only the last one works. Since the last one works i assume it is because it was last to be parsed on pageLoad. So how can i make it that when user clicks on the accordion pane, the usercontrol is ->?re-initialized?<- so that it could work.
Here is 1st UserControl: uctl1.ascx
[Code]....
Here is 2nd UserControl: uctl2.ascx
[Code]....
when i click on pane and fill up the information in textboxes i click on submit and usercontrol should postback to server for processing.

I'm having a really strange issue with the MaskedEditExtnder. I've attached some markup for one of the textboxes. I'm using a MaskedEditExtender and MaskedEditValidator along with a CalendarExtender so the user has the option to type the date or click on an image and pick the date.
So, if I enter/pick a date then select a control that forces a postback (usually a dropdownlist but not always) when the page is returned the focus goes back to the textbox I just entered the date in. So what about the MaskedEdit, MaskedEditValidator, CalendarExtender would cause the page to return focus to the control being extended? See markup below - am I missing something??

Can anyone give me some VB to set focus to a control using the "FindControl" method. MyTextbox.focus() is not good enough because, for instance, I have a textbox called "Username" in the "CreateNewUserWizard" control which is within a Contentplaceholder on a child page so typing in "Username.focus()" does not work on the Page_Load event because Username simply does not have a Focus property.

I have a page that when auto or partial post back happens, focus is set to the address bar rather than the next control. The interesting thing is that when I put an alert in my RadScriptBlock, after the OK is clicked, focus goes to the correct control -or- if I put in an invalid location, focus is returned to the ExpLocation control & when a correct location is input the second time, the tab order/focus command works correctly (see code below).
That has this up top
