Problem Postingback in IE7

I am having a problem posting back in ie7 when a row is selected from a grid. I am using the following code:

<

telerik:RadGrid ID="grdDropBox" runat="server" AutoGenerateColumns="False"

GridLines="None" onselectedindexchanged="grdDropBox_SelectedIndexChanged"

Skin="Office2007" Width="827px"

ondeletecommand="grdDropBox_DeleteCommand" AllowAutomaticDeletes="True"

DataSourceID="SqlDropBoxDS" AllowAutomaticUpdates="True"

onneeddatasource="grdDropBox_NeedDataSource">

<MasterTableView datakeynames="Email,UploadedBy,UploadDate"

datasourceid="SqlDropBoxDS">

<telerik:GridButtonColumn CommandName="Select" HeaderText="Download"

Text="Download" UniqueName="SelectRow">

</telerik:GridButtonColumn>

<telerik:GridBoundColumn DataField="Email" HeaderText="Email"

UniqueName="Email" ReadOnly="True" SortExpression="Email">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FileName" HeaderText="FileName"

UniqueName="FileName" SortExpression="FileName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FileType" HeaderText="FileType"

UniqueName="FileType" SortExpression="FileType">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UploadedBy" HeaderText="UploadedBy"

UniqueName="UploadedBy" ReadOnly="True" SortExpression="UploadedBy">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UploadDate" HeaderText="UploadDate"

UniqueName="UploadDate" DataType="System.DateTime" ReadOnly="True"

SortExpression="UploadDate">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="EmailNotify" HeaderText="EmailNotify"

UniqueName="EmailNotify" SortExpression="EmailNotify">

</telerik:GridBoundColumn>

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete"

HeaderText="Delete" Text="Delete" UniqueName="DeleteColumn"

ConfirmText="Are you sure you want to delete this item?"

ConfirmTitle="Delete Confirmation">

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</ClientSettings>

</telerik:RadGrid>

The strange part is this works fine in firefox, in VS development server, and on the same network as the Webserver. It doesn't postback when outside of the network (Both the Download and Delete don't). Any ideas?

Itemteplate / Skin

Hi Telerik-Support,

I use a RadContextmenu and set the skin to "default". Than I build up an menu with an submenu. On this submenu I use asp:Checkboxes in an item template.

My probelm is that the "default" style isn't inherit. If i hove over an root menu item it gets an gray colored background image. If i hove over an submenu template item nothing happens? Why and how can I solve this behavour?

Thanks a lot.

CommandItemTemplate

How can you create two separate CommandItemTemplate on the grid, so that one can be on the top while the other at the bottom and they are function differently? For example, one use to clear all filters and the other one use to export to excel etc.

Thanks for the help.

Question about setting row expanding to false...

I am using the heirchary model and have gotten my detail talbles to correctly display using the DetailTableData bind event. My question is if the parent row doesnt have any children is it possible to not show the expand row icon to the left of the parent row? Would I accomplish this in the itemdatabound event?

problem trying to display "No records to display" on page load

Hello

I am having problems trying to display the message (or a custom message) "No records to diplay" in the radgrid when my page first loads.

I have tried putting in this code on the page load event:

If Not IsPostBack Then

rgListingWithImages.DataSource =

New Object() {}

'rgListingWithImages.Rebind()

End If

but I get this error.
Both DataSource and DataSourceID are defined on 'rgListingWithImages'. Remove one definition.

RadEditor ImageManager Paths

I am developing an internal web application and when I upload an image using RadEditor Imageupload, it successfully gets uploaded to a virtual directory in the web application. The application creates a document and it can be viewed by anyone outside the network.

So when I insert the images, it reference the virtual directory which is only accessible internally.
So when people outside the network views the document, they are unable to see the images in the document since the image reference is set to the virtual folder.

I can copy the images in the virtual folder to a folder that is accessible from www. In that case how can I change the image reference to point to the external image.

for example.
Image upload folder in only Internal
~/images/a.jpg

I can copy this a.jpg to another server which is available externally.
Say I copy access the image using
www.test.org/images/a.jpg

How can I change the image reference from ~/images/a.jpg to www.test.org/images/a.jpg/

please let me know.
thanks

editor.pasteHtml is inserting <STRONG> tag before Paragraph

Hi,

I want to set styles to Paragaraph, I am able to set the styles but after setting style the selected paragraphs are becoming bold. Editor is adding <Strong> tag to the selected Paragraphs. Please tell me any work around for this, or is it issue in Editor when we do PasteHtml with P tags. This happens for P tags

My Code is as below:

var cssTextFormed = "text-align:"+textAlign+";line-height:"+lineSpace+";text-indent:"+hanging+"; margin: "+ beforePara+ " "+ rightindents +" "+ afterPara +" "+ leftindents +";";

var editor =$find("RadEditor1");

//if more than one paragrah is selected then replace p tag with applied style
var selection = editor.getSelectionHtml().replace(/<P/g,'<P style='+cssTextFormed);
editor.pasteHtml(selection);
