Resource for dynamically created controls?

I looked up the web and there are plenty of issues/workarounds with handling the viewstates for dynamically created controls and statically designed elements. However they are more like hacks and I'd prefer to avoid going to that route.

What is the best approach and gotchas if I need to create RadEditor, RadCombo, RadTextbox dynamically?

My page would have some static elements on the top and bottom of the page, and the center of the page would have some dynamically created controls based on what the user has selected from a dropdown.

It will have a RadUpload statically created and a button to validate during postback.
After postback if validation fails, the values the user entered in the dynamically created controls (RadTextbox/Combo/Editor) should remain.

I don't see VS2010 to mention any additional feature to the dynamically created control's viewstate issue.

Feature Date Validation For RadDatePicker

Hello ALL,

I have used RadDatePicker into my web page, Now i want to restrict feature date selection to user.

So i had set the max date property as today's date from code behind.it's working properly, user can't able to select feature date from calender.

In case if user try to add feature date manually, then date picker highlighted with warning symbol with yellow color.

But when i click on save button and checked Page.IsValid property, it will always give me true and i got the date picker selected value as null.

How can i validate RadDatePicker for feature date? Please help me.

Here is my code :

aspx :
<telerik:RadDatePicker ID="dpCompletedDate" Calendar-ShowRowHeaders="false"
Skin="Office2007" runat="server" />

Page Load cs :
dpCompletedDate.MaxDate = System.DateTime.Now;

Inserting an item Client-Side using insertItem()

Hello;

I'm trying to add a new row to a Radgrid client-side using insertItem() and then update all inserted items in a single batch.

I've got several questions:

1) What's the correct way to use the client-side API call insertItem() ?

2) Can insert operations be batched like edit operations?

Thanks...

Edit Caption Behavior

I am using a usercontrol for my grid edit form and have editmode set to popup.

When I edit an item in my grid, the popup edit form shows along with a caption bar along the top with a big "X" close-button at the right end of the caption bar.

I read here:

http://www.telerik.com/help/aspnet-ajax/grdcustomeditforms.html

"Please note that all settings related to the edit form caption are applied only if the EditFormType is "AutoGenerated". Otherwise a caption is not rendered automatically by RadGrid, however, you can add a custom caption in the edit form template or user control edit form."

I thought this meant that having my EditFormType set to "WebUserControl" would suppress the rendering of a caption on the popup edit form.

I don't mind having a caption (I am able to put change the caption content via the captiondatavield and captionformatstring) but I am having trouble controlling its appearance. The caption bar that renders is only about half as wide as the usercontrol that I have created as my edit form and any of the formatting I apply to *it* seems to only render as wide as the caption. That is, I put a border around my edit form control and when it pops up, the border only shows around the left half of the form (showing only as wide as the rendered caption).

Is there a way to force the caption to be as wide as my control? If not, is there a way to specifically suppress the rendering of the caption?

Thanks,

Mike

Calling web service from popup

Hello,
I open popup window which displays a page. When I try to call web service from pageLoad() function, I always get a message "Insufficient stack space". When I put function to main window and call if with wnd.BrowserWindow.MyFunction(), I get no errors and everything works fine. Does this mean I cannot call web service directly from RadWindow?
Thank you.

RadGrid Inplace editing with standard Update/Cancel buttons but without edit column

Hi

I have a rad grid that shows a list of names and a delete column. I do not want the user to be able to edit the names, they should only be able to delete (using the delete column) and insert (using the EditMode="InPlace" built in elements).

How do I get the standard built in Update/Cancel command buttons to appear without having to have an Edit column in my grid?

Thanks
Corina

Getting credentials prompt when trying to upload file

Hello,

I am using Rad Ajax controls version 2011.2.915. Whenever a user running Windows XP and IE 7 tries to upload a file from My Documents or another network location they get prompted with a windows credential box. If they enter their credentials IE 7 locks up.

The RadAsyncUpload works fine in windows 7 IE8. If the IE 7 users try a file from their C drive, that functions correctly as well.

I have tried to allow Anonymous Access to the website in IIS (5) but this does not make a difference. Placing these lines of Javascript before the upload control also do not help.

<script type="text/javascript">

     

   if (Telerik.Web.UI.RadAsyncUpload != null && Telerik.Web.UI.RadAsyncUpload.Modules != null) {

         Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function() { return false; };

         Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function() { return false; };

</script

How do I either disable the flash and silverlight, or how do I fix the permissions problem?

Here is how I am using the uploader in a RadGrid, once as an attachment column for inserting, and once as a control in a template column for editing.

<telerik:GridAttachmentColumn AttachmentDataField="Data" FileName="Name"

FileNameTextField="Name"

HeaderText="View Attachment" UniqueName="Data" DataTextField="Name"

AttachmentKeyFields="FormSequenceNr" EditFormHeaderTextFormat="">

</telerik:GridAttachmentColumn>

<telerik:GridTemplateColumn HeaderText="File" DataField="Name" FilterControlAltText="Filter TemplateColumn column"

UniqueName="Name">

<ItemTemplate>

<asp:Label runat="server" ID="lblName" Text='<%# Eval("Name") %>' />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadAsyncUpload runat="server" ID="AsyncUpload1" OnClientFileUploaded="OnClientFileUploaded"

OnValidatingFile="RadAsyncUpload1_ValidatingFile">

</telerik:RadAsyncUpload>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Thanks

Resize RadTreeView, based on .aspx Size

I'm working with the RadTreeView, within an HTML table;

An objective for this .aspx web page is to have the RadTreeView resize, according to the resizing of a .aspx web page;

For example, if the width or height of the .aspx web page is resized to a point where the .aspx web page has less width or less height than the RadTreeView itself - the RadTreeView will resize accordingly with scroll bars;

Hopefully the description provides a clear understanding; Best regards - Rob

<table style="width: 100%;">

<tr>

<td align="left" valign="top">

<telerik:RadTreeView ID="RadTreeView1" runat="server"

OnNodeExpand="RadTreeView1_NodeExpand" ForeColor="Black"

Font-Names="Microsoft Sans Serif" onnodeclick="RadTreeView1_NodeClick"

Height="600px" Width="400px" Font-Size="Medium">

</telerik:RadTreeView>
