Security issue in ImageEditor that allows saving the image in an up-level folder

The RadImageEditor control allowed saving image files (.png/.jpg/.gif) to an up-level folder on the server when the built-in storing of files is used. This issue did not affect implementations based on the content provider paragidm. It has been fixed since the Q1 2014 release of Telerik UI for ASP.NET AJAX (version 2014.1.225).

If you are using an older version of the controls and you do not wish to upgrade, there are two approaches that you can take in order to resolve the security issue:

You could replace the path separator from the file name in the event handler of the image editor’s ImageSaving event:

void ImageEditor_ImageSaving(object sender, Telerik.Web.UI.ImageEditorSavingEventArgs e)

{

e.FileName = e.FileName.Replace("/", "");

}
You could use a custom content provider to completely bypass the file handling approaches in the ImageEditor itself. Please check the following demo and help article on the matter for more information:
- http://demos.telerik.com/aspnet-ajax/imageeditor/examples/customcontentprovider/defaultcs.aspx

GridDateTimeColumn causing a weird problem

This issue has me totally lost.

I have a formview with several radcontrols and a UserControl.

The user control has a RadGrid and an ObjectDataSource.

When I call the UpdateItem method on the formview with the following code:

protected void BtnSave_Click(object

sender, EventArgs e)

{

if (Page.IsValid)

{

this.MyFormView.UpdateItem(true);

}

I get the following exception:

InvalidOperationException: Collection was modified; enumeration operation may not execute

Here's the stack trace:

at System.Web.UI.ControlCollection.ControlCollectionEnumerator.MoveNext()

at System.Web.UI.WebControls.DataBoundControlHelper.ExtractValuesFromBindableControls(IOrderedDictionary dictionary, Control container)

at System.Web.UI.WebControls.DataBoundControlHelper.ExtractValuesFromBindableControls(IOrderedDictionary dictionary, Control container)

-------------

The stack trace doesn't say much and didn't help me track the problem, but I ended up figuring out that what was causing the problem is a GridDateTimeColumn defined inside the radgrid (there's only one datetime column) that's inside my user control as such:

<telerik:GridDateTimeColumn DataField="DeadlineDate" UniqueName="DeadlineDate"
DataFormatString="{0:dd MMM yyyy}" HeaderText="Deadline" />

When I remove this column, the call to the formview's UpdateItem method works well. When I put it back, I get the error again. I tried playing w/ the properties, binding to another datetime column, recreating the whole file from scratch, removing everything in the code behind file of the user control, and nothing works. The weird thing is, I have datetime columns in other usercontrols built the same way, and everything works fine there.

Here's the usercontrol definition:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="GridViewTest.ascx.cs"

Inherits="TestSolution.WebUI.UserControls.GridViewTest" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadGrid ID="TestRadGrid" runat="server" AllowFilteringByColumn="True" AutoGenerateColumns="false"

AllowPaging="True" AllowSorting="True" CellSpacing="0" DataSourceID="TestDataSource"

GridLines="None" Skin="Office2007">

<MasterTableView EditMode="InPlace" DataKeyNames="PeriodID">

<Columns>

<telerik:GridBoundColumn DataField="PeriodID" UniqueName="PeriodID"

Visible="false" />

<telerik:GridBoundColumn DataField="SpecificityID" UniqueName="SpecificityID" />

<telerik:GridDateTimeColumn DataField="DeadlineDate" UniqueName="DeadlineDate" DataFormatString="{0:dd MMM yyyy}"

HeaderText="Deadline " />

<telerik:GridBoundColumn DataField="DeadlineDate" UniqueName="DeadlineDate" HeaderText="Deadline" />

<telerik:GridNumericColumn DataField="OutstandingAmountBeforeDeadline" UniqueName="OutstandingAmountBeforeDeadline"

NumericType="Number" HeaderText="O/S Before Repayment" />

<telerik:GridNumericColumn DataField="InterestAmount" UniqueName="InterestAmount"

NumericType="Number" HeaderText="Interest" />

<telerik:GridCheckBoxColumn DataField="ToDelete" UniqueName="ToDelete" HeaderText="Delete" />

<telerik:GridEditCommandColumn ButtonType="PushButton" InsertText="Insert" EditText="Edit"

CancelText="Cancel" UniqueName="EditCommandColumn" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:ObjectDataSource ID="TestDataSource" runat="server" TypeName="TestSolution.WebUI.ObjectDataSource.TestDataSource"

SelectMethod="GetTestTableByCriterias">

<SelectParameters>

<asp:Parameter Name="TestType" Type="Int32" />

<asp:Parameter Name="SpecificityID" Type="Int32" />

</SelectParameters>

</asp:ObjectDataSource>

Any ideas? :(

RadWindow + IFrame Positioning in IE

Looking for some positioning/z-index guidance on the RadWindow. I've played around for probably too much time and haven't budged a thing so I'm hoping an expert can speed me along.

We have a page with multiple user controls and a ton of Rad items (grids, comboboxes, windows, oh my!). In multiple places we are using RadWindows to pop up attachment selection, searches, etc. These RadWindows are not playing well with an Iframe that is a document preview. The RadWindow is appearing partially behind (or fully behind in some cases) an Iframe doc preview when the file type is unsupported (which is just a white box, since the file in question was opened/saved to the native desktop). This is only happening in IE.

The fact that it is only happening in IE and that IE handles z-indexes differently really leads me to believe I'm not handling the z-index correctly. I've attached two example images. Both of these have a large white box in the document preview area because I have chosen a file of type .docx. The first image shows a fully blocked RadWindow. The second a partially blocked RadWindow.

Z-index of fully blocked: 3001
Z-index of partially blocked: 3005

Any advice (even of a non z-index variety) would be greatly appreciated. Thanks!

Question about clicking an Image in a cell...

Hello All,
I have a grid, that in the ItemCommand event handler subroutine I handle the "RowClick" with a call to another sub... Now here's where it gets interesting... In the first cell/column of a row, I have an Image. I would like it so that when the user "Clicks" the image that it fires off a server side event that I can capture and call my same sub that handles the "RowClick" event... I know that if the user clicks the "white" space around the image, that the ItemCommand event is fired for the "RowClick", but NOT for clicking inside the image itself... The image is large enough and takes up a good bit of the cell that there is very little "white" space around it, and that it would seem to be very frustrating that nothing happens when the image itself is clicked...
Right now, how things stand is that it's a plain column, and a plain image in the cell. I have NOT looked at placing an ImageButton in the cell, as I have not used that control before, nor have I looked at a GridImageColumn or a GridBinaryImageColumn yet. the two alternative column types don't quite seem to be want I looking for, as the images are not stored in a database or in a particular URL...
So... Is there anyway to have the Image fire off some sort of server event when it is clicked or not??? That is the question of the day...

Thanks in advance!,

RadGrid DataSource Switching

Hi All,

I have an all code-behind solution where I build out the grid columns based upon the DataView acquired from the SqlDataSource. I'd like to be able to dynamically switch the SqlDataSource for the grid with different drop-down-list options. I'm doing something like this, but it appears that I'm getting vague errors. I am re-using the SqlDatasource variable and re-building whenever the User switches the drop-down-list option. I also re-build my RadGrid's columns using the new DataView from the updated SqlDataSource. I then rebind(); just like in that link, but I do not autogenerate columns.

Can you anyone please help me?

Thanks,
Mark
