Warning message when exporting to excel 2007

I am using the newest RadGrid and its export funationlity. THe data is being exported just fine, however, there is this annoying security warning message.

Question 1:

How do I get around this?

Question 2:

I am able to get around this by exporting to CSV. However. now, I am not able to add style attributes to certain cells. I have number cells whos content sometimes start with 0. These leading zeros are automatically removed unless I am able to add a style attribute to that cell. How do I fix that?

Adding item fires image button event on a different page view.

I have a tabstrip with a MultiPage control.
On the first PageView I have an editor control with some text boxes and a couple of image buttons.
On the second PageView I have a couple of GridControls.
On the first grid I use the add new record command item. Only one column is editable.

When I hit the enter key after adding the data in the text box. The image button click event for the first image button on the first page view is called. The sender object is the image button but it is not visible when the enter key is hit. If the check image is clicked the item is added normally.

Since the ImageClickEventArgs x y coordinates are always zero when the event is erroniously called, I have a work around, but it is not apparent what would be causing this problem.

Fire Select button on page load

Can you tell me how to fire the select button on page load? I would like to have the file browse window appear right away when the page loads without the user having to click the select button.

I have attempted to add to the onclientadded handler with no luck. I am trying to configure a simple one file upload within a window control.

Seems like a simple task not sure why I am having so much trouble with it.

Thanks,
Dave

Sys.Webforms.PageRequestManager errors

I keep getting this error. Using 2008 Q2 of radcontrols. Free version (still haven't bought) . This would not be such a big deal if it was not completely random, causing me to look like a friggin idiot every time it pops up and I have to say, " I have no idea why this is happening ". this occurance was not happening with the Q1 release. It is mysterious and confusing when testing. Can someone explain how to get rid of it please. If I drop all the ajax events, it still occur s wherever the dll is referenced.

error 1
Sys.WebForms.PageRequestManagerParserErrorException. The message received from the server could not be parsed. Common caused for this error are when the response is modified by calls to response.write(), Response filters, HttpModules, or server trace is enabled. Details: Error Parsing near '
<!Doctype HTML P' .

error 2
Sys.WebForms.PageRequestManagerParserErrorException. The message received from the server could not be parsed. Common caused for this error are when the response is modified by calls to response.write(), Response filters, HttpModules, or server trace is enabled.

Separator

How can control the look of a radpanelitem that is a separator?

This is how i create the radpanelitem:

Dim rpiSeparator As New RadPanelItem
rpiSeparator.IsSeparator = True
rpiSeparator.CssClass = "subMenuSeparator"
rpiSeparator.Text = "<hr />"
radPanel.items.add(rpiSeparator)

And this is my css:
.subMenuSeparator
{
padding-top:5px;
padding-left:0px;
padding-right:0px;
color:#000000;
}

It does not seem to have any effect.

I am using GroupByFields in the grid. And I want to access the values in foreach GridItem in the code behind page. how can I access that?
Following is the code.

Eg:

<

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

AllowPaging="True" GridLines="None" AllowMultiRowSelection="true" ShowGroupPanel="False"

Skin="Office2007" OnPreRender="personalGridView_PreRender" OnPageIndexChanged="personalGridView_PageIndexChanged">

</FilterMenu>

<telerik:GridGroupByExpression>

<telerik:GridGroupByField FieldAlias="Name" FieldName="Name" FormatString="" HeaderText="" />

</SelectFields>

<telerik:GridGroupByField FieldName="Name" FieldAlias="Name" FormatString="" HeaderText="" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

</RowIndicatorColumn>

</ExpandCollapseColumn>

<telerik:GridClientSelectColumn CommandName="Select">

            <telerik:GridDropDownColumn  
        
                                                     UniqueName="DropDownListCategory" 
        
                                                     ListTextField="Category"

                                                     DataSourceID="SqlDataSource2" 
        
                                                     HeaderText="Category" 
        
                                                     DataField="Category" 
        
                                                     DropDownControlType="RadComboBox" 
        
                                                     AllowSorting="true">  
        
                                                    </telerik:GridDropDownColumn>

But the contents of the dropdown can change depending on a selection elsewhere on the page, so Id like to be able to set the datasource using c#

Jump to Selected Item on Sort w/ Paging

I have a multi-selectable, sortable, paged grid. I'm able to retain the user's selections after a sort/page operation. However, I haven't found a way to jump to the page which contains the user's selected item on a sort operation. For example, if I select a given row on page 1 of the grid and then sort by a given column, I would like to do the following:

sort the grid
jump from page 1 to page n (which now contains the previously selected item)
reselect that item
scroll to that item

How is this accomplished w/ RadGrid?
