Hello Telerik Team,

I have searched all forums threads and didn't find relevant answer.

Please could you provide a sample, how to sort radgrid clicking on a non-grouped column that takes the entire dataset into consideration, yet maintains the integrity of the groups ? After click on some column, it should order groups based on column value, as well. 

Here is similar issue http://www.telerik.com/community/forums/aspnet/grid/sorting-a-grouped-grid.aspx without solution...

Consider this example:
GroupA
     Value5
     Value3
GroupB
     Value1

This happens when I click the sort of a column:

GroupA
     Value3
     Value5
GroupB
     Value1

What I'm wanting:

GroupB
     Value1
GroupA
     Value3
     Value5

Thank you

Best regards

Hi,

I have created RadTollTip for RadScheduler appointment on RadScheduler's OnAppointmentCreated event as shown below.

protected void RadScheduler1_AppointmentCreated(object sender, AppointmentCreatedEventArgs e)
        {
LinkButton lnkButtonMore = new LinkButton();                 lnkButtonMore.ID = "lnkBtn" + e.Appointment.ID.ToString();                 lnkButtonMore.Attributes.Add("runat", "server");                    lnkButtonMore.Text = e.Appointment.Subject ;                    lnkButtonMore.ToolTip = "";                 lnkButtonMore.ForeColor = System.Drawing.Color.Black;                 lnkButtonMore.Enabled = false;                 lnkButtonMore.Font.Size = FontUnit.Point(8);                 lnkButtonMore.Height = new Unit(100, UnitType.Percentage);                 lnkButtonMore.Width = new Unit(100, UnitType.Percentage);                 lnkButtonMore.Font.Underline = false; 

RadToolTip radTooltip = new RadToolTip();
                radTooltip.ID = "radAppr"+ e.Appointment.ID.ToString();;
                radTooltip.Attributes.Add("runat", "server");
                radTooltip.Text = strbulToolTip.ToString();
                radTooltip.BorderStyle = BorderStyle.None;
                radTooltip.TargetControlID = e.Appointment.ClientID;
                radTooltip.IsClientID = true;
                radTooltip.AutoCloseDelay = 0;
                radTooltip.ShowDelay = 0;
                radTooltip.HideDelay = 0;
                radTooltip.Position = ToolTipPosition.MiddleLeft;
                radTooltip.RelativeTo = ToolTipRelativeDisplay.Element;
                radTooltip.HideEvent = ToolTipHideEvent.LeaveTargetAndToolTip;  

e.Container.Controls.Add(lnkButtonMore);             
                e.Container.Controls.Add(radTooltip);
            }

Where "strbulToolTip" contains the table which I show as ToolTip of appointment.

Issue occurs when I keep mouse pointer on appointment for 5 to 10 seconds and then remove mouse pointer from appointment, ToolTip does not hide.

If I remove mouse pointer from appointment in less then 5 seconds then it hides ToolTip.

Hello,
I have a RadGrid with an Edit/Insert popup form based on a template. The RadGrid is AJAX enabled programmatically in the Page_Load() method.



In the template there is a RadListBox.


When I click on the Edit or Add buttons nothing happens but a Javascript exception is thrown:

Uncaught Sys.ArgumentUndefinedException: Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: type

1. Error$create ScriptResource.axd:222
   Error$argumentUndefined ScriptResource.axd:346
   Function$_validateParameterType         ScriptResource.axd:130
   Function$_validateParameter ScriptResource.axd:99
   Function$_validateParams ScriptResource.axd:67
   Sys$Component$create ScriptResource.axd:2698
   (anonymous function) TechnicalData.aspx:7
   Sys$_Application$add_init ScriptResource.axd:3991
   (anonymous function) TechnicalData.aspx:1
   ...
   

   
   

   
   

I spent some time debugging the client code to find out what was causing such exception and it seemed that Javascript had no knowledge of the RadListBox (type undefined).

I found a temporary workaround by placing a dummy empty RadListBox in another place of the page.

This is not peculiar to RadListBox controls as it happens also with all other RadControls.

My conclusion is that if the edit form template contains RadControls which are nowhere else defined on the page, the associated client scripts and definitions are not properly loaded when using AJAX. Without enabling AJAX behavior everything works fine.

What am I doing wrong? Is there a solution?

Thanks in advance,

Mauro

Hello,

OK, so I have a page that has a radgrid and a form.  When creating a new record via the form and rebinding the grid, it works fine.  When initially binding the grid, it works fine.  Only when clicking a delete button in the grid, handling the custom command, and rebinding, do I get this error.

On the form, there are radtextbox, radcombobox, radspell, and other controls.  I noticed the RadSpell.CreateChildCOntrols in the stacktrace... does that mean that's where the error is?  I also see a reference to ASP.views_shared_header_ascx.__Render__control1, which is a user control and has some controls/AJAX in it.

Also, I'm binding on PreRender - this is not an issue for the rest of the app that does the same thing; and in this page, it only happens on this one spot, not in the other two spots, which are bound on prerender...

Why would this error be happening?

Thanks.

Dear All,

How can I get radfilter selected expression as a string so that I can filter datasource and rebind the grid.

Thank you

Hi,
     We are using RadGrid like this: Using default skin


         <telerik:RadGrid ID="rgdAccts" runat="server" AutoGenerateColumns="False" CellSpacing="0" GridLines="None"
            AllowSorting="True" AllowMultiRowEdit="True"
            OnItemDataBound="rgdAccts_ItemDataBound" OnBiffExporting="rgdAccts_BiffExporting" >
        <ClientSettings AllowExpandCollapse="false" AllowGroupExpandCollapse="false">
            <Selecting EnableDragToSelectRows="false" />
            <Scrolling AllowScroll="true" />
            <Resizing AllowColumnResize="true" AllowResizeToFit="true" ShowRowIndicatorColumn="false" />
        </ClientSettings>
        <MasterTableView DataKeyNames="AcctID">
           .........
              grid bound columns....
              <telerik:GridTemplateColumn DataField="PermissionID" UniqueName="PermissionID">
                    <EditItemTemplate>
                        <asp:RadioButtonList ID="rblPermission" runat="server" DataValueField="Custom"
                            DataTextField="ValueCustom" OnLoad="rblPermission_Load" RepeatDirection="Horizontal"
                            CssClass="grid-radiobuttonlist" />
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>
 
          When the page is loaded and look into html, all the rows are getting displayed as 'rgEditRow'. No alternate row is Shown. So, alternate row colors are not displayed. Entire grid (all rows) are of same color. We need to apply alternate row color style to this grid. When I looked into default skin, I see styles only for rgRow, rgAltRow and rgEditRow. So, how can I apply different colors to alter rows. I prefer to do it in skin rather than doing in the grid locally. Because we have similar requirements on many asp.net pages.

Thanks,
Prathiba

I have spent the couple days researching my issue and have not been able to get it to work correctly.  There are a few topics on StackOverflow that are related to this issue and reading them has helped me but I'm at a bit of a roadblock and would appreciate a push in the right direction.

I wrote a small .NET 3.5 VB.NET web application for a client that allows users to maintain some data.  I'm using the RadGrid and RadComboBox controls and it consists of 3 pages.  One requirement I was not completely fond of was that the user wanted to make all of her changes then hit a save button at the end instead of saving back to the DB each time she applied her changes to the grid.  

I'm using an session object to store a collection of objects on each page and want to prompt the user with a dialog if they attempt to change the value of a dropdown or leave the page when there are pending actions.  After a lot of research here and in other places, I decided to create a hidden field on the page and update its value each time the action collection is updated on the server side.  Then I want to evaluate that value and if it's greater than 0, I want to prompt the user to save changes.

My function:




My hidden field declaration:



My server side code:


When I debug the application and add a record to my grid, the server side code is executed correctly.  I have also verified that the hidden control is found by the javascript function.  What I haven't been able to figure out, though, is why the hidden field value is not found by the function.

Any help is greatly appreciated.  Thank you!
