Want to Dynamically Create a RadWindow in External Server-side Code

In my website project I have a top-level file called "Common.cs" that is shared by all the forms in the project. It contains common code that needs to access the Website UI. I'd like to dynamically create a dialog box that will allow the user to enter additional comments in the event of an error.

I've written some code that is not crashing but yet no RadWindow is appearing. Here's the crux of what I have so far:

public static void ShowErrorDialog(string msg, Constants.ErrorCode category, string location, Control parent) { RadWindow rw = new RadWindow(); rw.ID = "rwErrorHandling"; rw.VisibleOnPageLoad = true; rw.CssClass = "errorDialog2"; rw.Behaviors = WindowBehaviors.Move; rw.EnableShadow = true; rw.VisibleStatusbar = false; rw.VisibleTitlebar = true; rw.Visible = true; 

//rw.AutoSize = true;<br>      rw.Width = 300;<br>      rw.Height = 200;<br>      rw.Modal = true;<br>      <br>      // Much more code here to create the contents of the dialog box<br>      <br>      parent.Page.Controls[0].FindControl("form1").Controls.Add(rw);<br>    }

And here's a sample call to the method:

Website.Common.ShowErrorDialog("Test message", Constants.ErrorCode.UnexpectedRecordCount, "buttonTest", Page);

Hoping someone can tell me why the RadWindow is not appearing,

Robert

P.S. In case it helps, here's displayed info from jQuery when I'm stepping through client-side code:

? $('div[id$=_rwNewMuckpile]')[0].id
"ctl00_ContentPlaceHolder1_Mucking_rwNewMuckpile"
 endsWith: function String$endsWith(suffix) {
 /// <summary locid="M:J#String.endsWith" />
 /// <param name="suffix" type="String"></param>
 /// <returns type="Boolean"></returns>
 var e = Function._validateParams(arguments, [
 {name: "suffix"
 startsWith: function String$startsWith(prefix) {
 /// <summary locid="M:J#String.startsWith" />
 /// <param name="prefix" type="String"></param>
 /// <returns type="Boolean"></returns>
 var e = Function._validateParams(arguments, [
 {name: "pre
 trim: function String$trim() {
 /// <summary locid="M:J#String.trim" />
 /// <returns type="String"></returns>
 if (arguments.length !== 0) throw Error.parameterCount();
 return this.replace(/^\s+|\s+$/g, '');
}
 trimEnd: function String$trimEnd() {
 /// <summary locid="M:J#String.trimEnd" />
 /// <returns type="String"></returns>
 if (arguments.length !== 0) throw Error.parameterCount();
 return this.replace(/\s+$/, '');
}
 trimStart: function String$trimStart() {
 /// <summary locid="M:J#String.trimStart" />
 /// <returns type="String"></returns>
 if (arguments.length !== 0) throw Error.parameterCount();
 return this.replace(/^\s+/, '');

So something "appears" to be there but if I make this call: $find($('div[id$=_rwNewMuckpile]')[0].id)
then I get 'null'. :-(

[Solved] Programmatically add a column to an existing detail table in hierarchy

Hi,

I tried this in the DetailTableDataBind event handler

GridBoundColumn b = new GridBoundColumn();

e.DetailTableView.Columns.Add(b);

b.HeaderText = "test";

the column is successfully added, but as soon as a postback occurs, the new column disappears. But adding a column the exact same way to the MasterTableView works as intended.

I am having the same issue as an unanswered question in the second half of this thread (by Bruno):

Thanks,

Problem with Inline Styling

I have defined a RadUpload control:

    <telerik:RadUpload MaxFileSize="512000" OverwriteExistingFiles="true" ControlObjectsVisibility="None"
          runat="server" ID="RadUpload1" OnValidatingFile="uploadMedia_ValidatingFile"
          OnClientFileSelected="uploadMedia_FileSelected" Width="500px" />

But this is rendered as:

<span class="ruFileWrap ruStyled" style="width: 80px;" jQuery171041561896132524767="11">
    <input class="ruFileInput" id="ctl00_MainContent_Edit1_RadUpload1file0" submitName="ctl00_MainContent_Edit1_RadUpload1file0" type="file" size="23" unselectable="on" _events="[object Object]"/>
    <label style="display: none;" for="ctl00_MainContent_Edit1_RadUpload1file0">
    <input class="ruFakeInput" id="ctl00_MainContent_Edit1_RadUpload1TextBox0" type="text" size="22"/>
    <label style="display: none;" for="ctl00_MainContent_Edit1_RadUpload1TextBox0">
    <input class="ruButton ruBrowse" type="button" value="Select"/>

You may notice the style="width: 80px;" property. That's the bit that's causing problems, it's 'cutting off' the right half of the control. I've traced the style using IE's developer tool but all it's telling me is that it's 'Inline.' Where is this styling defined? Is it possible to override the 80px?

Thanks a lot.

EDIT: Please note that this happens regardless of whether I'm setting the EnableFileInputSkinning and InputSize properties, these where just set in attempt to solve the problem, and it didn't work.

EDIT: Please remove this thread, reposted in the right place: http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/problem-with-inline-styling.aspx

Multiple select using shift key

Multiple selection works by using ctrl key, but we have to click 20-30 times if we have to select many items. If the nodes are sorted, is there a way to select them shift style, so that all leaf nodes are selected between 2 clicks.

Checkboxes in Tree Acting Like Radio Buttons

I have a treeview with a number of nodes that contain various editing controls that are generated from templates. The problem is that the checkboxes are being treated like radio buttons as it will only allow one at a time to be checked. When I check one, it appears the tree automatically unchecks any others in the entire tree, firing the checkchanged handler for each in its template.

This only seems to be exhibited when a checkbox is clicked, I can generate the tree with multiple check boxes checked, but as soon as you check one I see this behavior.

All the checkboxes have unique ID's.

When I place several checkboxes on the same page with their own checkchanged handlers, but outside of the tree, they do not demonstrate this behavior amongst themselves. Although even checking one of these, the ones in the tree do.

I added some code to the checkchanged handlers in the templates and checked the __EVENTTARGET param and kicked it out of any that didn't match the ID of the sender. This kept the underlying data correct, but when the page regenerates all the other checkboxes are still unchecked. This would seem to imply that the tree is somehow forcing this on the controls when they're rendered.

If not I don't know where else this would be coming from. Any insight is appreciated though.

how to get currently selected tag in editor in WYSIWYG mode

Hi,

I need to get the currently selected tag.
So, i am using editor.getSelectedElement();

in my editor has code in html like

<subelement id="717" type="complementary"><tag type="open" text="complementary" elem-tag="subelement">|</tag><tag type="open" text="p" elem-tag="p">|</tag>

An increasing amount of information on complementary and alternative medicine is becoming available. The scope of the BNF is restricted to the discussion of conventional medicines but reference is made to complementary treatments if they affect conventional therapy (e.g. interactions with St John's wort—see Appendix 1). Further information on herbal medicines is available at

the design mode content looks like below.

[Solved] RadCompression + ashx + Content-Length Header + Flush

After implementing the RadCompression model on a previously working ashx page I was using for secure file downloads, itstopped working in Firefox, Chrome, & Safari, but continued to work in IE (tested v9). I found 2 possible places for the error, but due to time constraints had to stop and simply remove the RadCompression module.

1.    On my development box, Win 7, IIS 7, flushing the data (context.Response.Flush()) between the header and the content caused the browsers listed above to report an invalid compression.

2. On my production server, Windows Server 2003, IIS 6, the browsers just sit there and spin, as if they are waiting for more content. I think this is due to my manually adding a "Content-Length" based on the size of the uncompressed content. Is there a sample showing the correct parameters to set when using RadCompression in this scenario?  My page, based on parameters, may return any of the following, and so I am also setting the content type and content-disposition headers manually:

    a.    HTML (text/html)
    b.    Text (text/plain)
    c.    Zip (application/zip)
    d.    Excel (application/vnd.ms-excel)
    e.    Excel 2007 (application/vns.openxmlformats-officedocument.spreadsheetml.sheet)
    f.    Jpg (image/jpeg)

These files are dynamically generated, so I would also like to specify "no-cache" in the sample as well.

The following is my working (without RadCompression) sample. (Again, it works in IE, but not others.)

Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

'''The following 2 lines do not seem to make a difference, but were added when trying to test

context.Response.Clear

context.Response.BufferOutput = True

'Get the filename

Dim fileType As String = context.Request.QueryString("t")

'Get the project name

Dim projectName As String = Managers.SessionManager.ProjectName(context.Session)

'Get the userId

Dim userId As Integer = Managers.SessionManager.UserId(context.Session)

'Make sure the project and user name are valid

Dim securePath As String = Utilities.IO.GetSecureDirectory(Managers.ConfigManager.SecureOutput, projectName, userId)

'Create the full physical path to the file

Dim fullPath As String = IO.Path.Combine(securePath, fileName)

'See if the file exist

If IO.File.Exists(fullPath) Then

'Open a fileinfo object for the file

Dim currentFileInfo As New IO.FileInfo(fullPath)

Case "zip"

context.Response.AddHeader("Content-Disposition", "attachment;filename=MyZip.zip")

context.Response.ContentType = "application/zip"

Case "export"

'Get the fileextension

Dim fileExtension As String = IO.Path.GetExtension(fullPath)

If fileExtension = ".html" OrElse fileExtension = ".htm" Then

context.Response.AddHeader("Content-Disposition", "attachment;filename=Export.htm")

context.Response.ContentType = "text/html"

ElseIf fileExtension = ".txt" Then

context.Response.AddHeader("Content-Disposition", "attachment;filename=Export.txt")

context.Response.ContentType = "text/plain"

ElseIf fileExtension = ".xls" Then

context.Response.AddHeader("Content-Disposition", "attachment;filename=Export.xls")

context.Response.ContentType = "application/vnd.ms-excel"

ElseIf fileExtension = ".xlsx" Then

context.Response.AddHeader("Content-Disposition", "attachment;filename=Export.xlsx")

context.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

End If

Case "print"

context.Response.ContentType = "text/html"

Case "image"

context.Response.AddHeader("Content-Disposition", "inline;filename=Print.jpg")

context.Response.ContentType = "image/jpeg"

End Select

'''The following line has had inconsistant results in some browsers

'context.Response.CacheControl = "no-cache"

'''Is the following line is another (unconfirmed) problem for RadCompression?

context.Response.AddHeader("Content-Length", currentFileInfo.Length.ToString)

context.Response.StatusCode = 200

''''The following line breaks RadCompression in IIS7
