Cannot Delete or Update using Custom Content Provider

I am building a custom content provider to allow FileExplorer to use RackSpace CloudFiles. So far, I've been able to get it to list directories and contents flawlessly. However, there seems to be an issue uploading and deleting files (objects).

In my provider class I have the required "DeleteFile" method (really you guys should have a Interface to implement, NOT a class to inherit) however the DeleteFile method is never called when deleting, same goes for the StoreFile method when uploading.

Instead I get the following error: The selected file could not be deleted because the application did not have enough permissions. Please contact system administrator

I have checked and the Delete and Upload paths are set correctly, and ViewState is turned on as well, but no matter what I do, the FileExplorer never actually calls the Content Provider methods...

ISSUE SOLUTION:

The solution is pretty simple... I did not have an overriding method in my provider for "CheckDeletePermissions" method. Unfortunately because these providers are setup to Inherit a base provider instead of Implementing an Interface there is nothing to "force" me as a programmer to implement all MANDATORY overrides... I guess it's a matter of preference but I enjoy using Interfaces, they do a great job of enforcing correct programming for providers.

At at any rate, I have implemented this override method and not instead of calling the base provider class for Deleting it's calling the customer provider on delete instead. I will also assume that overriding "CheckWritePermissions" will also take care of my uploading issue.

Happy Coding, good luck to the rest of you.

Edit column formatted as percentage cannot update

I have a radGrid which displays a couple of GridBoundColumns representing decimal data fields in editmode as a Percentage = DataFormatString="{p:0}", but if I go to edit one of these and click update I generate the following error, since the other textbox is displaying with " %" in the value, ..

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Input string was not in a correct format.

How can I have my cake and eat it too? I want to Display percentages as whole numbers and edit them the same way?
grid is named rdAsset

<

telerik:GridBoundColumn DataField="Target" DataType="System.Decimal" DataFormatString="{0:p2}" HeaderText="Target%" SortExpression="Target" UniqueName="Target">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="TargetRange" DataType="System.Decimal" DataFormatString="{0:p2}"

HeaderText="Target Range%" SortExpression="TargetRange" UniqueName="TargetRange">

</telerik:GridBoundColumn>

In the code behind, I have...

protected void rdAsset_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode )

{

GridEditFormItem item = e.Item as GridEditFormItem;

TextBox target = item["Target"].Controls[0] as TextBox;

target.Text =

String.Format("{0:p2}", (item.DataItem as DataRowView).Row["Target"]);

TextBox targetRange = item["TargetRange"].Controls[0] as TextBox;

targetRange.Text =

String.Format("{0:p2}", (item.DataItem as DataRowView).Row["TargetRange"]);

}

RadGrid Inside RadMultiPage Disappears when paging, sorting, etc...

I've seen a couple other posts about this, but none of them had an answer that actually worked. My problem is that I have a RadGrid inside of a RadMultiPage, and I'm using RadAjaxManager. Whenever I click to go to the next page, or change the page size, or anything of that nature, the RadGrid disappears. When looking at the source code the markup for the RadGrid does not appear, just a couple of div tags in its place. This is the code on my .aspx page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CreateAccount.aspx.cs" Inherits="DADCA.Account.CreateAccount" %>

I have absolutely no idea what I'm doing wrong. I tried to rebind the grid in the page load method, but still no dice. Any ideas?

Pre-populate content if the bound RadEditor is empty.

Hi Everyone,

Problem Statement: Inside of an ASP DetailsView, I have declared a RadEditor.   The content is bound inline with the content property.   When the field is empty, I need to display a stylized (greyed out or whatever..) set of template text.   This is to help the users properly fill in the field.   I can't seem to figure out the best way to accomplish this.

Tried so far:   Bind the content inline, and also put the template text in the content tags within the control declaration.

Is there something I can do in the DetailsView databind to check the contents then post the template text?

Here is the way I am binding this now:

<asp:TemplateField HeaderText="Summary" SortExpression="Summary">

<EditItemTemplate>

<telerik:RadEditor ID="reSummary" runat="server" Height="80" Width="500" ToolsFile="xml\RadEditorToolbars.xml"

Content='<%# Bind("Summary") %>'>

<CssFiles>

<telerik:EditorCssFile Value="Styles/EditorContentArea.css" />

</CssFiles>

</telerik:RadEditor>

<br />

</EditItemTemplate>

<InsertItemTemplate>

<asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("Summary") %>'></asp:TextBox>

</InsertItemTemplate>

<ItemTemplate>

<asp:Label ID="Label3" runat="server" Text='<%# Bind("Summary") %>'></asp:Label>

</ItemTemplate>

<ControlStyle Width="600px" />

<HeaderStyle HorizontalAlign="Right" VerticalAlign="Top" Width="600px" />

</asp:TemplateField>

Thanks,
Daniel

List Content missing in grid and VIew

Hi,

i do have an issue with the webparts delivered by by the SAK. I did a fresh install on our SP Farm (2 Servers with 2010 as Frontend) and everythings seems to work fine.
I activated the features on farm and collection level and were able to put the webparts on a page.
i added a list as shown in your video, but no list is visible.
After this i tried to add the SP List by Designer and this did the job.

Best regards

Move Child Node to different Parent Node?

I just recently purchased the Telerik Ajax RAD controls and I was wondering if it is possible to move a child node from one parent node to a different parent node in the TreeList control? I didn't see a demo for this type of functionality, so I was wondering if it's included. If not, would it be possible to customize the control to allow this functionality? I noticed a forum post "TreeList Drag'n'Drop Example (jQuery)" where someone customized the control to have drag and drop functionlity. Would that customization allow moving child nodes to different parent nodes (I'm not technical, so I can't read the code and try it out)?

Thanks!

RadEditor SearchPatterns

Hi. We're using the RadEditor but it's not allowing the user to upload any PowerPoint files. Having searched the topic it would seem that it should be a fairly simple case of amending the SearchPatterns, but this seems to have no affect. Below are the two variations I have used;
DocumentManager-SearchPatterns="*.*"
DocumentManager-SearchPatterns="*.doc, *.txt, *.docx, *.xls, *.xlsx, *.pdf, *.pps, *.ppsx, *.ppt, *.pptx"

To be precise, this relates to the document manager that you reach if you go to add a hyperlink into the content, then select the attachment icon next to the url finder, then select upload. It always shows the default:

File extensions allowed: *.doc, *.txt, *.docx, *.xls, *.xlsx, *.pdf

Hope you can help.

Thanks,
Chris

How to make RadGrid Cells Wrappable?

I have a RadGrid with 10 columns.

The horizontal scrollbar appears whereas I'd need the column data to be wrappable so that e.g. "FirstName Surname" appears in 2 lines rather than one line so that we won't need to have the scrollbar.

How could it be done?

Many thanks,

Grid
