[Solved] Footer aggregate causes "Specified Cast is not valid." exception

Whenever I try to set Aggregate="Sum" for an integer column, I get the "Specified Cast is not valid." exception. I've tried all kinds of things, but always get the exception. It works fine with Decimal columns.

These cause an exception:

    
            <rad:GridNumericColumn DataField="EstQty" HeaderText="Est. Qty." 
        
                        UniqueName="EstQtyColumn" Aggregate="Sum" NumericType="Number" 
        
                        DataType="System.Int32" DataFormatString="{0:N0}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle Width="6em" /> 
        
            </rad:GridNumericColumn> 
        
            <rad:GridNumericColumn DataField="FinalQty" HeaderText="Final Qty." 
        
                        UniqueName="FinalQtyColumn" Aggregate="Sum" NumericType="Number" 
        
                        DataType="System.Int32" DataFormatString="{0:N0}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle Width="6em" /> 
        
            </rad:GridNumericColumn>

While this works fine:

    
            <rad:GridNumericColumn DataField="Postage" HeaderText="Postage" UniqueName="PostageColumn" 
        
                        NumericType="Currency" DataType="System.Decimal" Aggregate="Sum" 
        
                        FooterAggregateFormatString="{0:C}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle HorizontalAlign="Right" /> 
        
            </rad:GridNumericColumn>

I'm using Q2 2008 SP1, btw.

radtreeview forecolor problem

Hi everybody,

I have a little problem with my treeview.

I populate my treeview on demand, when I open a node I perform a check and if this if true I set the forecolor of the node to red in the following way

RadTreeNode

node = new RadTreeNode();

node.ForeColor = System.Drawing.

Color.Red;

e.Node.Nodes.Add(node);

but as soon as I click on a node or perform an action on my contest menu the forecolor return to black.

Can somebody explain me what I'm doing wrong? or if it isn't possible to set a permanetly another forecolor?

Thank you very much

Style tag

Hi,

We are using Rad Editor and creating articles which will be sent in a mail to all the users.
The articles are viewed the same way created in outlook 2003, but when it is viewed in oulook 2007 its looking very ugly as the style tags are no more recognized in oulook 2007 due to some changes as it doesn't have html engine etc...
one of the main problem is when we are changing the image properties like width, height editor stores in style tag, which is not recognized by oulook 2007 and showing the actual size.
so we want the properies of images to directly under the image tag instead of style.
is there any way to sort out this problem.
Please do reply ASAP, as its creating problems in our production.
Thanks in advance.

Regards,
Bala.

[Solved] Put all rows into edit mode on page load

Hi,

I am trying to convert one of our existing tables into a telerik grid; the table has 5 columns of various types including non editable text, editable text and checkboxes. I need to be able to have every row in edit mode on page load, any changes made will be saved using a save button on the page. I have tried the suggestions in http://www.telerik.com/help/aspnet/grid/grddefaulteditmodeforgriditemsoninitialload.html but can only get the bottom row to go into edit mode.

I also need the checkbox columns to have a "select/deselect" all column, there are multiple checkbox columns so selecting/deselecting should not select or deselect the row, is there a setting that does this?

Many thanks

[Solved] PDF Export - Include Summary

I want to export the RadGrid to PDF and at the top of the PDF I want to show a summary of what the RadGrid contains. The summary is shown above the RadGrid on the web page. I understand how to export the RadGrid to PDF. My problem is that because it only exports what is in the MasterTableView, I can't include the summary in that PDF. Is there anyway to accomplish this?

Thanks,

[Solved] passing data between controls clientside?

Hello,

Is there a way to pass data from one control to another, using clientside JavaScript, without using AjaxManager?

What I would like to accomplish, is to display the child items in a grid control when a node is selected in a treeview control. Vice versa, when an item is selected in the grid, I would like the treeview to display it also.

One way I can think of to go about this is to call a web service from a treeview clientside NodeClicked handler. The web service would get data for the grid, and then will callback the updateGrid function to rebind it with the data.

Is there another, direct way via Javascript, without having to make a web service round trip?

Thanks,
Alex
