Hi
I am trying to generate telerik controls dynamically on a page using xml and xslt.
I am getting "unknown server tag telerik:RadTextBox" error while trying to create the control.
Below is my aspx code:
<%@ Page language="c#" Codebehind="XmlTransformerForm.aspx.cs" AutoEventWireup="false" Inherits="PubsWeb.XmlTransform.XmlTransformerForm" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

        </FORM>
   </BODY>
</HTML>
Xslt Code:
<xsl:element name="telerik:{@type}">
                                        <xsl:attribute name="runat">server</xsl:attribute>
                                        <xsl:for-each select="./PROPERTIES/PROPERTY">
                                            <xsl:attribute name="{@name}"><xsl:value-of select="current()"></xsl:value-of></xsl:attribute>
                                        </xsl:for-each>
                                        <xsl:for-each select="./LISTITEMS/LISTITEM">

                                        </xsl:for-each>
                                    </xsl:element>

Xml Code:
<FIELD type="RadTextBox" label="Requestor:" required="true">
          <PROPERTIES>
            <PROPERTY name="ID">txtRequestor</PROPERTY>
            <PROPERTY name="ReadOnly">True</PROPERTY>
          </PROPERTIES>
        </FIELD>

RadDatePicker PopUp Position

Can anyone suggest a solution to our problem?

We have a number of nested container divs set at 100% height. This is causing the popup from the RadDatePicker to be positioned incorrectly at the top of the page or sometimes off the screen.

WebResource.axd getting Vulnerabilities on IBM App Scan test

I have did app scan on a ASP.Net Application developed with Telerik Controls,

I received following vulnerabilities related to telerik Controls

1. Catchable SSL Page Found

2. Client Side (Javascript) Cookie References

3.Query parameter in SSL Request

As per our Security feedback , these issues should be rectified, I had already explained that these are just assemblies which doesnt do any database operation and can be treated as false positive. But they suggested to refer Australian Cyber Security Centre report on Advisory: Vulnerable versions of Telerik
UI being actively exploited by APT actor.

Please support in order to resolve the issue.

Node.Controls.Clear() not working for dynamically created/added controls

I have the following treeview

<telerik:RadTreeView ID="tvProcInst" runat="server" CheckBoxes="True" CausesValidation="False"

DataTextField="LEVEL_NAME" DataValueField="LEVEL_CODE" RenderMode="Lightweight"

CssClass="Left" MultipleSelect="True">

</telerik:RadTreeView>

that is loaded from a linq query once in the page load. That all works fine. Each time a user checks a node I add a combobox with the following code

Private Sub tvProcInst_NodeCheck(sender As Object, e As RadTreeNodeEventArgs) Handles tvProcInst.NodeCheck

Dim cb As New RadComboBox

Dim cn As New RadTreeNode

If e.Node.ParentNode IsNot Nothing Then

Return

End If

If e.Node.HasControls Then

If Not e.Node.Checked Then

e.Node.Controls.Clear()

End If

Return

End If

Dim row As New RadComboBoxItem

row.Value = "R"

row.Text = "Recurring"

cb.Items.Add(row)

row = New RadComboBoxItem

row.Value = "N"

row.Text = "Non-Recurring"

cb.Items.Add(row)

cb.ID = "cb" & e.Node.Value

cn.Controls.Add(cb)

cn.Checkable = False

e.Node.Nodes.Add(cn)

e.Node.Expanded = True

End Sub

it will add the combobox no problem, but will not clear it upon unchecking the checkbox, and when checking another checkbox it will create the new one, but the previously created combobox goes away or goes invisible I can't figure out which because the controls.count is still 1 but yet I can't see it.

Hopefully this makes sense. If screen shots will help I can supply them if needed.

Problem opening file from RadGrid GridButtonColumn

I am having a problem that I have been trying for a while to figure out.

I have a RadGrid that has a GridButtonColumn connected to c# function that I use to pull path and file info from a database and open the file from a file server.

If I use this on an ASPX page by itself, it works like a charm.

If I include this same RadGrid control and code in another RadGrid Edit Form, the function runs and appears to complete successfully.

I debug it and it runs and completes just the same, the file.FullName is right, just like when it tuns in the other form, but the Response.Flush does not open the file.

When the Response.Flush runs in the debugger, I see the focus go back to the browser for a flash and back to the debugger, but no file open dialog or anything else.

I bet someone out there knows what is going on. Help!

Thanks!

Here is my ItemCommand call:

protected void OpenAttchTable_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "Open")// CommandName of LinkButton

{

GridDataItem item = e.Item as GridDataItem;

String filePath = @item["filePath"].Text;

String fileName = item["fileName"].Text;

String FullFilePath = @filePath + fileName;

FileInfo file = new FileInfo(FullFilePath);

String fileExt = file.Extension;

switch (fileExt)

{

case ".csv":

Response.ContentType = "text/csv";

break;

case ".doc":

Response.ContentType = "application/msword";

break;

case ".docx":

Response.ContentType = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";

break;

case ".gif":

Response.ContentType = "image/gif";

break;

case ".jpeg":

Response.ContentType = "image/jpeg";

break;

case ".jpg":

Response.ContentType = "image/jpeg";

break;

case ".pdf":

Response.ContentType = "application/pdf";

break;

case ".png":

Response.ContentType = "image/png";

break;

case ".ppt":

Response.ContentType = "application/vnd.ms-powerpoint";

break;

case ".pptx":

Response.ContentType = "application/vnd.openxmlformats-officedocument.presentationml.presentation";

break;

case ".txt":

Response.ContentType = "text/plain";

break;

case ".xls":

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

break;

case ".xlsx":

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

break;

default:

Response.ContentType = "application/octet-stream";

break;

}

if (file.Exists)

{

if (file.Length > 30000000)

{

String Message = "The file exceeds the Maximum length of 30 Megabytess.";

ClientScript.RegisterStartupScript(this.GetType(), "Warnings", "alert('" + Message + "');", true);

}

else

{

Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);

Response.AddHeader("Content-Length", file.Length.ToString());

Response.ClearContent();

Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);

Response.AddHeader("Content-Length", file.Length.ToString());

Response.TransmitFile(file.FullName);

Response.Flush();

Response.End();

}
