Rad upload does not work in User Control

Hi,

I have Radupload control in .ascx file some thing like this.

<tel:RadUpload ID="ruConsent" runat="server" AllowedFileExtensions="jpg,jpeg,png,gif,pdf,doc,docx,xls,xlsx"

ControlObjectsVisibility="None" Height="24px" MaxFileSize="10485760">

</tel:RadUpload>

On Submit button's Click event on code behind

i have written liek this:

if (ruConsent.UploadedFiles.Count > 0 && ruConsent.InvalidFiles.Count == 0)

{

// upload file

}

else

{

//Show error message that files are not valid

}

but i always ruConsent.UploadedFiles.Count remains 0. If i put it out side of RadAjaxPanel then it is working fine. But when kept inside it is not working. Any idea why ?

Customizing Tags written by RadEditor

Hello,

Is it possible to customize the HTML tags written by RADEditor when a modification is made in the content (eg. adding comment, adding hyperlink, changing text to bold etc). I need to modify the tags in order to add information about the user who is making the change. This enables me to track changes in a document.

Thanks,
James

fastest way to remove nodes on the client side

what is the fastest way to remove nodes on the client side? I am using

node.get_parent().get_nodes().removeAt(0)

to get this functionality, but it looks to take comparatively more time, like to remove 200 nodes it takes around 2-3 seconds. Is there any other efficient method/way to achieve this.

astest way to insert nodes on the client side

radtreeview has addNodesTo() method for faster adding a treenodecollection to the treeview. Do we have some simillar kind of method even to insert a treenodecollection to the treeview on the client side. Right now we can only insert one record at a time in the treeview, so is there some way to insert a collection of nodes to the treeview on the client side so that the output is fast.

DropDownList by ItemTemplate in RadGrid (Update data and Select item)

Hi,

I have a few questions to ask. I'm not able to update the data and select the item from the dropdownlist.
I have the code here. It is the exact same things i refer from ( http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultvb.aspx# ). Only change the dropdownlist to ItemTemplate
because it is not populate from the databinding.

<telerik:GridTemplateColumn HeaderText="Branch" SortExpression="Branch" UniqueName="TemplateColumn"

EditFormColumnIndex="1">

<ItemTemplate>

<asp:Label runat="server" ID="lblBranch" ><%# DataBinder.Eval(Container.DataItem, "Branch")%></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<asp:DropDownList ID="DropDownList1" runat="server" >

<asp:ListItem Value="KL" >KL Head Office</asp:ListItem>

<asp:ListItem Value="PG" >Penang</asp:ListItem>

<asp:ListItem Value="JB" >Johor Bahru</asp:ListItem>

</asp:DropDownList>

</EditItemTemplate>

</telerik:GridTemplateColumn>

If I put SelectedValue='<%# Bind("Branch") %>' at the EditItemTemplate I can update the data but
I cannot add new record. It will appear this error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException:
'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
And if I remove the SelectedValue, I can add new record but I cannot update the data.
It will appear this error:
User with ID 3 cannot be updated. Reason: Cannot insert the value NULL into column 'Branch', table 'eDMS42.dbo.TblBranchApprover'; column does not allow nulls. UPDATE fails.
The statement has been terminated.
It's been bugging me for a week now. Please help me out.
