I like Telerik TV, I do. But it is, if we're honest, just about showing the latest functionality without actually trying to TEACH you anything. I've said this before, and I'll not be afraid to say it again; Telerik could benefit A LOT from getting together with a firm like Pluralsight. I would love to see Pluralsight standard courses on Kendo, Sitefinity and Open Access.

I have a page that has multiple tabs using the telerik:RadMultiPage and RadTabStrip controls. 
Those tabs are user controls and some have RadGrids, which uses a RadRadToolipManager control to fire a page as a menu.
This works fine from tab to tab. However, it appears that once one tab is loaded and its corresponding grid's toolip is loaded, the previous tab's grid's tooltips no longer fire.

Each tab's tooltip gets wrired up in its RadGrid's ItemDataBound event, of course.
Then The RadToolTipManager's OnAjaxUpdate and UpdateToolTip methods get called.

Again, everything works fine, and when a new tab is clicked its grid tooltip fires fine, but, the previous tab's grid's tooltips doesn't fire if I were to go back and try it.

Addendum:
I noticed that when I click a new tab, the Page_Load of the previously clicked tabs will fire. In the Page_Load of each tab, I have the code:  this.RadToolTipManager2.TargetControls.Clear();

I have this because when the tab's grid is sorted, I have to clear the target controls lest they maintain the wrong data. At least that is the solution I came up with.

So, now I may pose the question, is my solution above (maintain tooltip integrity on a grid sort) the right one? If not, I could remove it ( thus solving my current problem) and implement it the correct way.

Thanks for any info.

Hi!

I have a scenario with a RadGrid binded to a ObjectDataSource ( DataSourceID = "DS")


I've noticed then when I export da grid the  " grid.MasterTableView.ExportToExcel();" fires the GetList() method twice. This doesn't happens when I rebind the grid after the user clicked the search button. This only happens when exporting the grid. What may be causing the GetList method is being called twice each time call the export.?

Best regards

Hi,  I have a dataset that has a column called bold that's a bit.   When it's true I want that row to be bold, otherwise not.  How can I do this in radgrid?  Thanks in advance

I have a grid that I've added a custom CommandItemTemplate to.  The template contains (among other things) a link button with the CommandName of 'InitInsert'.  This button is working great for the purposes of adding new records to the grid.

Dear Friend I will add two Scanerio that will explain you the clear bugs that we have with rad Chart XAxis!

I am using above code and in this I add XAxis DataLabel Column when we use this it will show me result mention in screen shots A.

Now when we comment this XAxis check below code

It will show the result mention in Image B!

SO the problem is When we will use X Axis DataLable Column
1) It will hide the last series 
2) The Label got messup

Plesase suggest good ways to fix it!

Thanks

Hi, I'm currently populating a list of bookings by expanding the taking all the appointments in my scheduler and putting it into a datatable.  However my issue is that I'm unable to retrieve the room_Id or in most causes we refer to it as resource_ID for my bookings.

Is there a way to call my Appointment object to retrieve the resource_Id assigned to the specific booking.

 DataTable tanning_Availiability = new DataTable();

            tanning_Availiability.Columns.Add("Subject");
            tanning_Availiability.Columns.Add("Start");
            tanning_Availiability.Columns.Add("End");
            tanning_Availiability.Columns.Add("room_Id");

            foreach (Appointment a in scTanning_Availiability.Appointments)
            {
                //Occurrences of a recurrence master are not generated untill they      
                //are within RadScheduler's visible range. This mandates the occurrences     
                //information to be extracted from the Master's recurrence rule as follows:     
                if (a.RecurrenceState == RecurrenceState.Master)
                {
                    RecurrenceRule parsedRule;
                    RecurrenceRule.TryParse(a.RecurrenceRule.ToString(), out parsedRule);

                    //If a recurring appointment does not have specified end time it will have     
                    //endless occurrences. In this case you can explicitly put a restriction:  
                    string Date = Request.QueryString["Date"];
                    DateTime ConvDate = Convert.ToDateTime(Date);

                    parsedRule.SetEffectiveRange(ConvDate, ConvDate.AddDays(1));

                    foreach (DateTime occurrence in parsedRule.Occurrences)
                    {
                        tanning_Availiability.Rows.Add(new string[] { a.Subject.ToString(), occurrence.AddHours(-6).ToString(), occurrence.Add(a.Duration).AddHours(-6).ToString(), a.Attributes.Keys.ToString() });
                    }
                }
                else //Get the rest of the appointments     

                    //If the SelectedDate of RadScheduler is set so that the visible range encompasses occurences of      
                    //a recurring appointement, these occurences will be generated now so they will be added once again     
                    //to the DataTable. To prevent this, we use the following check:     
                    if (a.RecurrenceState != RecurrenceState.Occurrence)
                    {
                        tanning_Availiability.Rows.Add(new string[] { a.Subject.ToString(), a.Start.AddHours(-6).ToString(), a.End.AddHours(-6).ToString(), a.Attributes.Keys.ToString() });
                    }
            }

I need to enter elasped time in the format hh:mm:ss

The RadTimePicker is almost perfect except it is designed for time of day, not elapsed time, its not correct how it looks and  behaves for elapsed time.

Using the Masked Text box as shown below is less than ideal, since unless the user completey enters the data correctly(never happens), it will generate an error on the server side.

Any Ideas?

Hi Team,
we have Telerick Q2 2010 license in our project. can we use the same license for chart control's. or do we require any other license.
Advance Thanking you.

Mr.Perfect.

Hello, I am hoping that someone can come to my rescue with this issue.  I have been tearing my hair out and just cannot figure out a solution....  I want a ListView that displays images stored in SQL.  I have a Stored Procedure that returns the data, including a Thumbnail Image that should be displayed.  The data type of the Thumbnail Image is varbinary(MAX).  Locally, it works perfectly.  However, once I publish to the server, it doesn't.  I have three items to display, each with a picture.  The first time, the page loads, it will display image 1, but not image 2 and 3.  If I click Refresh, it will display Image 2 and 3, but not Image 1.  If I click Refresh again, it will display Image 2, but not Image 1 and 3, etc, etc, etc.  I used the code found here:  http://demos.telerik.com/aspnet-ajax/binaryimage/examples/default/defaultvb.aspx?product=listview to create my page.  I even created a blank page, no master page, no tables, no style, etc and literally just copied in the code, changed the DataSource, and the Field Names.  Locally = Perfect.  Server=Same issue.  I'm really at a loss here and would love any insight....  please, please, please, save my forehead from further bruising!
