Hi Team,

When I try renaming a folder in treeview pane, I am getting following error:

Stack Trace:
at System.String.Substring(Int32 startIndex, Int32 length)
at Telerik.Web.UI.RadFileExplorer.RenameTreeNode(RadTreeNode node, String newName)
at Telerik.Web.UI.RadFileExplorer.RadTreeView1_NodeEdit(Object sender, RadTreeNodeEditEventArgs e)
at Telerik.Web.UI.RadTreeView.OnNodeEdit(RadTreeNodeEditEventArgs e)

at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

However, file rename operation works fine. Can you please investigate the issue?

Radgrid with multi detail tables

I have a radgrid with a 3-tier structure (master -> detail -> detaildetail)

In my ItemDataBound event:

protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

... code referencing e.Item

}

how can I determine which "tier" e.Item is?

The <telerik:GridTableView> markup does not appear to allow me to specify a separate ItemDataBound handler for each "tier".

Thanks,

.

RadGrid, SQLDataSource, and Oracle database

I have an ASP.Net page with a RadGrid which is populated by the SQLDataSource.

I am trying to set up the RadGrid so the user edit some fields in the RadGrid for a record and click on update. But I cannot get it to work. When clicking on update, I get "ORA-01036: illegal variable name/number" error.

I am connecting to an Oracle database.

In looking at your demos, none of them use EditMode = "InPlace". They either use an Edit Form or some custom things like textboxes, comboboxes, etc.

I have tried having a simple update command in SQLDataSource like the following:

UpdateCommand="UPDATE ADMIN.RSDC_SCRAP_CREDIT_RATE SET LAST_UPDATE = CURRENT_DATE"

That statement should update the LAST_UPDATE field with the Current Date/Time for all the records but it is causing the error as well. That statement was just a test to see if the parameters in the SQLDataSource is causing the error and/or the Update statement is causing the error.

Usually I set up a RadGrid to use NeedDataSource but alot of your demos and documentation for editing and updating records in the RadGrid indicate using SQLDataSource instead.

Either way I am trying to find a way for the user to edit fields in the RadGrid and update the record.

Please help!

Here is my ASP.net page:

RadEditor with PageLayout - iPhone

When using the RadEditor and the RadPageLayout together things do not render correctly. As you can see from the image the editor does not push the buttons down far enough and they are in the editor box area. How do we fix this?

Inconsistent Behaviour of Spreadsheet

Hi,

I am currently evaluating Telerik Controls for our next project.

I wish to use spreadsheet for holding data before i paste it into telerik grid.

I have observed that it does not behave as it does in the demo. The keyboard movement is not very smooth and pasting data from excel into it either does not happen at all or happens very late.

Below is the code I have used in aspx file and nothing in cs file. Let me know if i am doing something wrong.

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<div id="divSheet">

<telerik:RadSpreadsheet ID="RadSpreadsheet1" runat="server"></telerik:RadSpreadsheet>

</div>

Potential security vulnerability when using the Telerik RadEditor

Hi guys,

One of the options of the RadEditor is an option to create links using UI (see the attached screenshot RedEditorVulnerability.jpg)

Here is an option to open a new tab when clicking this link on a front-end site.

What I've recently found is this article with an example https://dev.to/ben/the-targetblank-vulnerability-by-example which says that using the "target=_blank" is a potential security hole for any site in any browser for now. Also there are some suggestions regarding on how to prevent this (by adding the rel="noopener noreferrer" attribute to a link).

So I'd like to ask you to add a possibility in the Hyperlink Manager to secure such links (e.g. some kind of checkbox "Protect my link from the target=_blank vulnerability").

This functionality will be very helpful for those clients who are focused on their sites' security.

Thank you!
