I have tried the combobox example here

but I can't edit anything in the combobox. I have read the documentation and as far as I understand I do write but still it's not possible to write anything

Can somebody give me perhaps a short example what settings I need to have to edit in a combobox

When I select the text outside the editor like headers and select the Font and Size from the HTMLEditorExtender dropdowns, it modifies the selected text's font and size.

For example in http://www.asp.net/AjaxLibrary/AjaxControlToolkitSampleSite/HTMLEditorExtender/HTMLEditorExtender.aspx page, if I select the header "HTMLEditorExtender Demonstration" and then choose the font 'WingDings' from dropdown it changes the heading font, same applies to the font size.

Even the labels 'Font' and 'Size' before these dropdowns can be changed using these dropdowns, which mess up the entire page.

Someone please help me how to resolve this problem.

Thanks.

Hi Folks,

Hoping someone can help me on this:

I am using a maskededit extender on a textbox

I want a user to be able to input a decimal value up with no more than 2 decimal places
In a standard scenario this is fine as I can set the mask="9.99"

But,
I would like the digits before the decimal to be any number of digits, not specific to the mask
Is there a way to make the mask just for the digits after the decimal?

So effectively the mask would be mask="anynumber.99"

Javascript is not really a runner becuase I need to be able to set the mask from code-behind also

Thanks

Paullyie

you can call this function

function RestoreFocus_For_AutoPostBack() {
    var oldId;

    var page = Sys.WebForms.PageRequestManager.getInstance();
    page.add_beginRequest(SaveOldId);
    page.add_endRequest(SetNewFocus);

    function SetNewFocus(source, args) {
        $("#" + oldId).next().focus();
    }
    function SaveOldId(source, args) {
        oldId = args.get_postBackElement().id;$("#" + oldId).next().blur();

Hi,

I use ajax call to upload file, during the upload I want to show a progress bar or ajax-loader image.

The ajax call code follows -

$.ajax({                                url: "fileHandler.ashx",                                dataType: 'script',                                cache: false,                                async: false,                                contentType: false,                                processData: false,                                data: form_data,                         // Setting the data attribute of ajax with file_data                                type: 'post',                                progress: function (e) {                                    if (e.lengthComputable) {                                        $('#stam').html('Uploading...' + Math.round(e.loaded / e.total * 100));                                    }                                },                                complete: function () {                                    $('#waitDIV').hide();                                    alert('Done');                                }                            });

How can I show a progress bar to the user ?

I attached a textbox to an htmlextender, and it works, but certain html tags are rejected.

For instance, I went into source view, and put the following equation:

<p style="text-align:center"><strong>P₁₂ = P₁ + P₂</strong></p>

Submitting the textbox (via a submit button in a form) give me text minus that section (the equation).

Is this a bug?

Thanks,

Hi All,

while it appears simple to create a login interface using AJAX (http://msdn.microsoft.com/en-us/library/bb398896(v=vs.100).aspx), I cannot figure out how to replace the create user wizard with AJAX.

Any suggestion about how to accomplish the above?

I'm trying to use the AsyncFileUpload control along with an UpdatePanel and UpdateProgress but can't seem to get it to work correctly.

What I want to do is use the AsyncFileUpload to select a file to process, click a button, have the UpdateProgress control display an animated gif and message "Processing file...", when the processing is complete some text like "Processing complete" is written to a Label.

Right now with my current code, before the page loads I get an unresponsive script warning.  I click "Stop script" in the window displaying the script warning to close the window.  I can click the AsyncFileUpload button and upload a file for processing, but then when I click the button to process the file, the UpdateProgress does not display.  When the file is finished "processing" the message is displayed in the Label correctly.

Below is my code:

I have an asp-net website that lets people view dialogue.  One way to obtain dialogue is via chat programs like skype. . You just paste the transcript from your skype into the website.  The problem that my co-worker raised is that people might not want to use Skype, because they have their main, known identity, and if they are practicing conversation, they might want to use an anonymous identity.  Skype can allow two identities in one computer, but its a pain to learn how to do this for our users..

So we looked at google chat, which is also quite complicated for users.

So we finally decided to integrate chat into our system.   One advantage is that this would also give our users knowledge of who-ever else was using our system and was willing to chat with them for the purpose of our website.

I went to codeplex, and found an out-dated chat with a database that made no sense - a field that was string was a foreign key of a field that was integer.  'nuget' also was disappointing.   Does anyone know of a good chat for the above purpose?  That doesn't require much programming?  That uses ajax and asp.net?

I ave a modal popup that opoens wheni  user wants to log a ride.  The ride date cannot be in the future or more than 2 weeks past. I use a range validator for this. owever, when i click on the insert button it does not display the error in the validation summary. I have the DiIsplay property set to None and associated with the validation group. If Ichange it to Dynamic it is displayed correctly within the form, but not in the summary. I changed the validation to check if the Page is valid and Show the popup if it is not, but the error is not displayed.

The HTML:

<InsertItemTemplate><table class="auto-style4"><tr><td class="tdlt_50" colspan="5"><asp:ValidationSummary ID="vgrpadd" runat="server" ShowSummary="true" DisplayMode="BulletList" /></td><td>&nbsp;</td></tr><tr><td class="tdlt_50">&nbsp;</td><td class="tdrt_100">Date:</td><td class="tdlt_100"><asp:TextBox ID="tbdate" runat="server" CssClass="tdlt_75"

The code:

 protected void InsertButton_Click(object sender, EventArgs e)
   {
        Page.Validate();
        if (!IsValid)
        {
            RangeValidator Range = (RangeValidator)FormView1.FindControl("RangeValidator1");
            DateTime dtnowdt = DateTime.Today;
            TextBox tbrdate = (TextBox)FormView1.FindControl("tbdate");

            //tbrdate.Text = dtnow;
            string dtmin = DateTime.Today.AddDays(-14).ToShortDateString();

            ValidationSummary vs = (ValidationSummary)FormView1.FindControl("vgrpadd");

            tbrdate.Text = dtnow;

After changing the font size of selected text, if we reselect the text and click on font size dropdown it resets the font size of the selected sext. For example, in the site http://www.asp.net/AjaxLibrary/AjaxControlToolkitSampleSite/HTMLEditorExtender/HTMLEditorExtender.aspx, select hello and change the font size to 7. Now clicking on the font size dropdown again will reset the selection. Same thing happens anytime we select the text with a different font size from default and click on the font size dropdown it resets the size.

Similar behavior happens while selecting Font dropdown also.

Please help me how to resolve this issue.

Thanks.

Hi, 

I am trying to use the Ajax Control Toolkit to implement the HTML Editor control for an application backoffice. 

<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"><title></title></head><body><form id="form1" runat="server"><div><asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager><cc1:Editor ID="Editor1" runat="server" /></div></form></body></html>

I am getting an error as described:

"Unhandled exception at line 168, column 5 in http://localhost/53984/WebForm1.aspx. 0x800a138f - JavaScript runtime error: Unable to get property 'UI' of undefined or null reference"

The error is at the line:

"$create(Sys.Extended.UI.HTMLEditor.ToolbarButton.Undo, {"activeModesIds":"0",downSrc":"/WebResource.axd?d=HaeI...."

I have tried to change the ScriptManager to the ToolkitScriptManager but it doesn't recognize the control 

<ajaxToolkit:ToolkitScriptManagerrunat="server"ID="sm1"/>

Any tips, or work arounds?

Thanks, 

Bruno
