[Solved] Using a GridCalculatedColumn with GridTemplateColumns

I would like to use a GridCalculatedColumn in conjunction with GridTemplateColumns. However, all of the samples on the Telerik Demo site utilize GridBoundColumns in conjunction with GridCalculatedColumns. I do not believe that I will be able to use a GridBoundColumn since I am binding to a collection of objects like so:

List<SelectedCourse> lstSelectedCourses = this.SelectedCourses;

//Bind the GridView schedule

gvSchedule.DataSource = lstSelectedCourses;

gvSchedule.DataBind();

When I display the columns in the GridView, I use the following syntax:

<columns>

<telerik:gridtemplatecolumn>

<itemtemplate>

<asp:hiddenfield id="hfCourseID" value='<%#Eval("CourseID") %>' runat="server" />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Category">

<itemtemplate>

<asp:label id="lblCategory" runat="server" text='<%#Eval("Category") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Subject">

<itemtemplate>

<asp:label id="lblSubject" runat="server" text='<%#Eval("Subject") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Days">

<itemtemplate>

<asp:label id="lblDays" runat="server" text='<%#Eval("Days") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Start Time">

<itemtemplate>

<asp:label id="lblStartTime" runat="server" text='<%#Eval("StartTime") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="End Time">

<itemtemplate>

<asp:label id="lblEndTime" runat="server" text='<%#Eval("EndTime") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Term">

<itemtemplate>

<asp:label id="lblTerm" runat="server" text='<%#Eval("Term") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Length (Weeks)">

<itemtemplate>

<asp:label id="lblCourseLength" runat="server" text='<%#Eval("CourseLength") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Location">

<itemtemplate>

<asp:label id="lblLocation" runat="server" text='<%#Eval("Location") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

<telerik:gridtemplatecolumn headertext="Cost">

<itemtemplate>

<asp:label id="lblCourseCost" runat="server" text='<%#Eval("Cost", "{0:C}") %>' />

</itemtemplate>

</telerik:gridtemplatecolumn>

</columns>

Is there a way to utilize the GridCalculatedColumn to sum up the value in the GridTemplateColumn for Cost?

Thanks.

Separate Insert/Cancel Buttons in Insert Mode

Hi

I'm currently developing Tablet based Web Application using Telerik Controls. I'm trying to prevent users from clicking/touching the cancel button when trying Inserting an item into the Grid. Is there a way to move the Cancel Image Button to the right hand side of the items when in Insert Mode?

I'm assuming I could build custom Cancel/Insert Buttons using RadButtonColumns on either side, but was hoping that there's maybe a simpler/cleaner way of achieving this.

Best Regards,

Landon

"Assembly Could Not Load" using New Version Q1 2011

I am using the RadMenu downloaded version Q1 2011 and cannot get the menu to load. The page errors out with the following error:

Parser Error Message: Could not load file or assembly 'Telerik.Web.UI, Version=2011.1.315.1040, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified.

I used the following website to assist me setting up the RadMenu http://www.sharemuch.com/2011/01/20/branding-sharepoint-2010-integrating-telerik-controls-in-sharepoint-site/

I modified the Telerik control to Version to the current build number as listed on this URL http://www.telerik.com/community/code-library/silverlight/general/submit-example.aspx

On the error page it states I am using Version Information: Microsoft .NET Framework Version:2.0.50727.5420; ASP.NET Version:2.0.50727.5420 However, when checking the Server Manager I have installed the Role Service of .Net Framework 3.5.1

Could this be the problem? Do I need to upgrade my .Net Framework Version to more recent copy?

As stated in this post http://www.telerik.com/community/forums/aspnet-ajax/editor/config-telerik-web-ui-dll-version-2010-1-415-35-in-sharepoint-2010.aspx I followed the instructions and placed code into the web.config for <SafeControl> and the <handlers> tags as directed.

What am I doing wrong?

I see in the threaded discussion that I may be using the wrong build:

----------
Posted on Jun 30, 2010 (permalink)

Hi Akhilaa,

I can see that you incorporated ASP.NET AJAX 3.5 in your MOSS site and you are trying to use the 2010.1.415.20 version of Telerik.Web.UI, which is built against .NET 2.0 framework. What you need to do is either use the 2010.1.415.35 version of Telerik.Web.UI, which is built against .NET 3.5 framework

---------

Is changing the build version the only issue? Are there any other roadblocks I should expect to find?

Please help!!!

Thank you.

How to display a Childnode to menu using SiteMapDataSource

We are creating a dynamic menu using a Mega Nav, a multi-column display and static menus. One of the columns holds a drop-down menu which we want to display the LISTS and LIBRARIES for the current SharePoint 2010 site. We want to have no other menu items displayed in this particular drop-down. Can someone help us how to get the results we are looking for? We have been attempting to use the SITEMAPDATASOURCE, however, this returns the entire site map structure which is way too much information. Based on which site a user is at this drop-down menu will only display the lists and libraries for that site only. It would dynamically look at the parent and children in the hierarchy and display the current location. While we believe this is the correct path we don't know the proper steps to code it correctly.

Regards,
Alex Dove

How to Remove root level List Library Discussions from menu

We are creating a dynamically created menu based off the DataSourceID="SiteMapDataSource" property. While this gives us the functionality we wanted it also displays LISTS, LIBRARIES and DISCUSSIONS on the top-level navigation. We only want to have top-level sites on the home page and sibling sub-sites displayed on the landing page of sub-sites. We have removed the Quick Launch to gain valuable real estate and therefore need to display the LISTS, LIBRARIES and DISCUSSIONS underneath a site menu item as a drop-down item. How do we accomplish this? I have attached a screenshot of our current site menu which displays ALL of the sitemap content in the top-level navigation. How do we move the LISTS, LIBRARIES and DISCUSSIONS into a separate drop-down? I have also attached 2 more images called "telerik_menu_dropdown.gif" which displays the menu items we need removed from the root menu and then image attachment named "telerik_menu_subsite_sample.gif" which is a child site of the parent. This top-level navigation is displayed correctly with all of the menu items listed vertically inside a drop-down menu.

Thanks
Alex

return css.ToString();

}

}

In the marble skin, we see two params {image} and {plotarea}. If we do not custom css, chart can show the background. However, I want to custom some its style, its background cannot show.

Please help.

Thanks / Phong Dang.

Invisible RadGrid doing DataBind

We have a very strange problem, we have a RadGrid that is invisible inside an UpdatePanel, that is set as the receiver of AJAX requests (along with other control). When the sender initiates an AJAX request, the RadGrid will try to DataBind, even though it is still invisible, which seem strange. Is this really expected behaviour or is it a bug? In my world, and invisible RadGrid should never try to DataBind by itself (all data operations for the grid is handled automatically).

e.Appointment.BackColor not Working.

hi

This is my code:

<ResourceTypes>
<telerik:ResourceType DataSourceID="sdsUsers" ForeignKeyField="UserID"
KeyField="UserID" Name="User_Name" TextField="User_Name" />
</ResourceTypes>

    Protected Sub RadScheduler1_AppointmentDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerEventArgs) Handles RadScheduler1.AppointmentDataBound
        If e.Appointment.Resources.GetResourceByType("User_Name") IsNot Nothing Then
            e.Appointment.BackColor = DataBinder.Eval(e.Appointment.Resources.GetResourceByType("User_Name").DataItem, "BackColor")
        End If
    End Sub

My user table schema:

UserID
User_Name
BackColor

I still do not get any color for the scheduler. What went wrong with my setting?
