How do you handle Server Side Exceptions on the Client Side?

The RadGrid offers a clientside event called OnDataBindingFailed which gets fired on the clientside (javascript) when there is a server side exception.

What is the equivalent for the RadAjaxPanel and RadAjaxManager? I want to be able to handle all exceptions as gracefully as possible.

Controlling Footers with Multiple Level Grouping

I want to have only the second level grouping have a footer with aggregate values. Not sure how to go about it.

________________________________________________________________________________

Group1 - need total in header

----- Grouping 2

----- Grouping 3

++++++++++++++++++++++|++++++++|+++|+++++|+++|++++++|+++|+++++++++++++

==Footer for 3 (need blank) ============================================

=============Footer for 2 ========================(NEED SUMS HERE==============

================Footer for 1 (need blank)============================================

================Footer for Grid (need blank)==========================================

Chart Subset Selections

Is there an easy way to implement a "Chart Subset Selection" feature? Rather than trying to explain what I mean, let me show you. Take a look at this Flash control (after you choose a city from the dropdown). While this implementation is slightly unresponsive and somewhat crude, it's actually a very nice UX for the user besides the unresponsiveness.

See this page for the example I'm referring to:

https://retaile-suite.energenuity.com/OPERATIONSDESK/Public/Weather/WeatherDashboard.aspx

Ultimately, they goal is to have a very high-level granularity chart to select a starting and ending point to view a much lower-granularity chart.

Is this currently possible or is there any chance of having some feature added so we can ultimately get to such a functionality? I can't tell you how many times (on date range-based charts) something like this would have been MUCH nicer than having two DatePickers specifying a Start Date and Stop Date.

Thanks!

GridClientSelectColumn/CheckBoxColumn

I am not sure of the suggested method on how to accomplish this. Any assistance would be greatly appreciated.

I have a grid bound to a boolean field. If the item value is 1, I want he checkbox checked and read only (GridCheckBoxColumn would work here). If the item value is 0, I want the checkbox enabled (GridCheckBoxColumn doesn't seem to work for this) and a postback when the user checks the box so I can update the database and rebind the two grids on the page.

In short, I want it so checks can never be removed, only added, and only one item checked per postback. Grid is bound with NeedDataSource event.

Any suggestions?

Here is what I have now. When it is done, I only want to have one column of checkboxes, the three below are all tests.

    
                        <telerik:RadGrid runat="server" ID="RadGrid1" AutoGenerateColumns="false"

Selecting All Records in a Paginated RadGrid

Hello,

I have a RadGrid on my webpage which has paging enabled, I also use the GridClientSelectColumn in order to select all displayed records. Here is an example:

    
            <telerik:RadGrid ID="radgrdEvaluator" AutoGenerateColumns="False" AllowPaging="True" AllowMultiRowSelection="True" PageSize="10" runat="server">  
        
                <MasterTableView DataKeyNames="EvaluatorID" ShowHeadersWhenNoRecords="True">  
        
                <Columns> 
        
                    <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn">  
        
                    <HeaderStyle Width="30px" HorizontalAlign="Center" /> 
        
                    <ItemStyle Width="30px" HorizontalAlign="Center" /> 
        
                    </telerik:GridClientSelectColumn> 
        
                    <telerik:GridBoundColumn DataField="EvaluatorID" HeaderText="EvaluatorID" UniqueName="EvaluatorIDData"></telerik:GridBoundColumn> 
        
                </Columns> 
        
                </MasterTableView> 
        
                <ClientSettings EnableRowHoverStyle="True">  
        
                <Selecting AllowRowSelect="True" /> 
        
                </ClientSettings> 
        
                <pagerstyle mode="NextPrevAndNumeric" AlwaysVisible="True" /> 
        
            </telerik:RadGrid>

In this example let's say I have 30 records that are returned but I have set the PageSize to 10 which would give me 3 pages of results. When I click the "select all" checkbox it only selects the 10 records of the displayed page. How can I get it so that the "select all" checkbox selects all 30 records, and not just the 10 displayed records without having to increase the PageSize property?

Thanks!
Jason

Changing Target Property - looks like a bug

Hi!

This looks like a bug - try to add a link in Rad editor and set the Target property to open in “Same Window”, link works fine (opens in new window).

Now when if you add another link to same page and set its Target property to any of the options, the Target property of previous link is set to “#” (which opens a new window).

Similarly on adding links to that page, sets the Target property of all previous links to “#” (Open in new window).
