I have an ASP.NET Web Forms project i am working with and need some help with my grid.

I have a pretty basic grid on my page. i am able to populate it mostly.

i use codebehind to bind a list to it from c#.

I need to figure out how to perform this,

I have the proper data in my list to be bound to the grid. i want to have my rows show some important data to my customer, but when he expands the row the data in the expansion is more data from the same list, for that row.

so when a user is browsing the grid, they can click on any row and it does its thing, but if they click the expander icon they get a bit more data about the row.

I hope i explained this well, im about to break out mspaint and draw it up...

When trying to use the export to excel functionality on my asp.net website the following error is displayed:

Could not load file or assembly 'Telerik.Windows.Documents.Spreadsheet, Version=2015.1.225.45, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Not sure why it is looking for version 2015.1.225.45 when the assembly references version 2016.2.421.40 and it is also set to Copy Local = True.

Have tried rebuild but still nothing. I have no idea where the old version is being referenced as I have searched the whole solution without success.

What is the solution here?

Bug introduced in build 2019.1.115+ causes 3 extra <p>&nbsp;</p> when user presses Enter key in FireFox.  Happens when Editor is in a Wizard with more than one step.  Bug does not occur in builds prior to 2019.1.115.

Try this to reproduce:

 <telerik:RadWizard runat="server" ID="rwMain" BorderStyle="Solid" BorderColor="LightGray" BorderWidth="1px" RenderMode="Lightweight" DisplayNavigationButtons="True">
        <WizardSteps>
            <telerik:RadWizardStep ID="RadWizardStep2" Title="Content Template" StepType="Step">
                <h1>hello!</h1>
            </telerik:RadWizardStep>
            <telerik:RadWizardStep ID="RadWizardStep3" Title="Content Editor" StepType="Step">
                <telerik:RadEditor ID="ContentEditor" runat="server" RenderMode="Lightweight"></telerik:RadEditor>
            </telerik:RadWizardStep>
        </WizardSteps>
    </telerik:RadWizard>

Hope you can fix it. 
Thank you!!

I am using RadWizard steps to make a survey. One step in the Radwizard is to select at least one service they use out of the list of options. When next button is hit, I need to validate that at least one item was checked. If I click next without checking anything, it just goes right to the next step. If I check then uncheck a box, only then does my "Please choose at least one of the options displayed" show up, and it still lets me hit next. What am I doing wrong? I also tried adding the auto postback =false to the Radwizard step, and the Radcheckboxlist itself, and neither helps.  Not sure what I am doing wrong. My code looks like this:

<telerik:RadWizardStep ID="RadWizardStep2" runat="server" Title="Services">
                <div>


                    <h3>Please mark all that apply:</h3>
                    <br />
                    <br />
                    <telerik:RadCheckBoxList ID="RadCheckBoxList1" runat="server">
                        <Items>
                            <telerik:ButtonListItem Text="Residential Services" Value="2" />
                            <telerik:ButtonListItem Text="Vocational Services" Value="3" />
                            <telerik:ButtonListItem Text="Transportation/NMT Services" Value="4" />
                            <telerik:ButtonListItem Text="Recreational Services" Value="5" />
                            <telerik:ButtonListItem Text="Supportive living services" Value="6" />
                            <telerik:ButtonListItem Text="Supported employment services" Value="7" />
                            <telerik:ButtonListItem Text="Other" Value="1" />
                        </Items>
                    </telerik:RadCheckBoxList>


                    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
                        ControlToValidate="RadCheckBoxList1"
                        ErrorMessage="Please choose at least one of the options displayed" />



                </div>
                <div>
                    <telerik:RadTextBox ID="OtherTextBox" runat="server" Visible="false"></telerik:RadTextBox>


                </div>

            </telerik:RadWizardStep>
