I try to postback my page to the server using ctrl+Enter sequence.Without UpdatePanel it works well, but it works only two times inside updatepanel and then my control loses the focus. So I have some questions:
1. Why my control loses the focus if it is located inside updatepanel?
2. What is the best way to use ctrl+Enter sequence to post the page to the server?
Here is my code:

I noticed that with some of the data controls (like gridview and listview) the page loses focus when you click edit, update, etc. So if your data control is somewhere lower on your page, you'd have to scroll down to get to it again. Is this normal or is there a way to keep the focus or location on where you were previously?
View 2 RepliesI have a webform that the user inputs a date via a javascript popup calander, then it auto populates a textbox with 45 days after the inputed date.
My question is is there a way to have a postback once the input date loses focus. Here is my page.

I have a GridView that has approximately 800 records. I have a search feature that finds a record and focuses to it. When I click Edit for that record, the Gridview flashes and goes back to the 1st row. If I search for the record again it is in edit mode. Is there some setting to keep focus where it is? I added the following code to try and keep focus, but it doesn't work.
[code]....
I have control like below
<textbox1>
<textbox2>
<dropdownlist1>
<radiobutton1> <radiobutton2>
<checkbox1>
<textbox3>
<button1>
I want to change focus on enter key press.
I basically want to show a dialog box with confirm or cancel options on it.
Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.
$('#buttonInUpdatePanel').live('click', function (event) {
event.preventDefault();
var item = this;
var title = 'Confirm';
var msg = 'Please confirm something';
var $dialog = $("<div id='myDialog'></div>")
.html(msg)
.dialog({
modal: true,
buttons: {
"Confirm": function () {
$(this).dialog("close");
__doPostBack('Button1', null); //tried this and .submit() on the button
//return true;
},
"Cancel": function () {
$(this).dialog("close");
//return false;
}
},
title: title
});
});
My UpdatePanel:
<asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:TextBox runat="server" ID="TextBox1" />
<asp:Button
ID="Button1"
Text="Add"
OnClick="AddExtraVehicle_Click"
runat="server" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
UPDATE:
I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.

View 3 RepliesI'm having a little problem with my file uploading. Does anybody know how to maintain the value in the FileUpload control between server posts?
I have a form which, among other things, uploads a file. I am using an ileUpload control (created dynamically) to let a user browse their PC for a file and then using the SaveAs method to upload the file to the server.When I'm selecting a file and Click on Next button for processing then selected file is lost.
Same is happening with me with HtmlTextArea (dynamically generated) , the problem was that I was not again re-initializing the controls after postback. What I did is re-initialized it in Init method of placeholder (as I have created/placed all dynamic controls in placeholder ).
But this thing is not working for fileupload control. I found solution in one of the forum is that "use hiddenField Control to transfer the selected file from the client to server"but this mechanism will only help to retain the name of file
in a hidden variable and the FileUpload1.PostedFile.SaveAs(filename) will not work bcz of absense of object (fileupload1).
here is code:

I am using VS2008 SP1 targeting .Net 2/3.5SP1 web site.
I am trying to set the focus to the user name TextBox which is inside an ASP.NET Login control.
I have tried to do this a couple of ways but none seem to be working. The page is loading but not going to the control.
Here is the code I've tried.
SetFocus(this.loginForm.FindControl("UserName"));
And
TextBox tbox = (TextBox)this.loginForm.FindControl("UserName");
if (tbox != null)
{
tbox.Focus();

In my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50);
After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus.
Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.

I have a repeater that has a LinkButton in the Item Template. The LinkButton displays a UserControl that consists of a FormView. The UserControl has an HTML Element that when clicked hides the UserControl by simply change the display of the control from 'block' to 'none'. If the 'Close' span is clicked, the UserControl is successfully hidden, but afterward, the 'Edit' linkbuttons no longer postback.
View 1 RepliesI have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)
But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.
how do I do that?
I have vertical image slidslow using datalist. on left side i have vertical scrolling thumbnail items. if we click the thumbnail i need to load all
related fullsize images on right side of the thumbnail. i need to load all full size images without posting the page.coz if i post the page my thumbnail images position get reset and starts from begining. so i need to avoid this.
Since we can't post data to cross domains, I want to post the data to my aspx page and a code-behind code will take the data and submit to cross domain (which is not being operated by me, so I don't have permission to modify source code for jsonp) and also the website to which I pass my post data is also returning a cookie which includes shopping cart info and I need to store it on my local browser cache as well.
What I know is I need to use WebResponse and WebRequest classes for that manner.
I have an ASP dropdownlist with AutoPostBack="true" and I want to do some javascript client side which can stop the postback if necessary. However, I can't get it to stop the postback.
<script type="text/javascript">
$(document).ready(function()
{
$("#ddl").bind('change', function() {
return false;
});
});
</script>
<select id="ddl" onchange="form.submit()">
<option value="">Item 1</option>
<option value="">Item 2</option>
<option value="">Item 3</option>
<option value="">Item 4</option>
<option value="">Item 5</option>
</select>
so i have a lightbox in which pops up an aspx page with textboxes and two buttons (submit - disabled and cancel - enabled). I wanted to enable my submit button ontextchange. it works fine when opened separately (not as a lightbox) but when i let it run normally with the lightbox function everytime ontextchange gets triggered the whole page refreshes disabling the lightbox.
<asp:TextBox ID="textBox1" runat="server" OnTextChanged="OnTextChanged_AttributesEdited" autopostback="true">
protected void OnTextChanged_AttributesEdited(object sender, EventArgs e)
{
btnSubmit.Enabled = true;
}
now if i take out the "autopostback=true" it then will not trigger the the ontextchanged. was wondering if is it better if javascript will be the way to go for enabling the button or is there a way where i can prevent the postback when ontextchanged is triggered?
when any Button control is clicked generally it Postback the page to itself, and the same page is regenerated.This is the usual defination of postback in context of a Button Control. But my dear friends i am confused that what is the actual mechanism behind this.Okey say for definition the above statement is fine but believe me i not not getting the actual meaning.What is posting back the Page? What is Page in browser's context? There is only html markup, JavaScript and CSS codes in browser's page.These make up the html page. I think there is no any relation of this Browser's page with ASP.NET Page class. What does it mean that browser's content is posted back to the Page itself ?
View 1 RepliesIve added checkbox to each gridview row like this:
[Code]....
I grab value of selected checkboxes like this:
[Code]....
So. It works fine, but when i change page of gridview, previous page loses selection and set all checkboxes to false.
Probably this is because paging causes postback, but still, is there an easy solution to rewrite my code, so it will work with paging?
Maybe theres a way to disable postback on page change?
I have gridview. In my griview, i have Fileupload template field.
but, problem is whenever my page get postback fileupload loses its content or selected file.
I have a javascript function on my Master page, how do I access it with a dropdownlist of a content page. Not from codebehind, I can do that, but from the control itself such as the onSelectedIndexChanged event.
