Hi,

When the record count is more than 500, the loading time of the appointments on the scheduler, loading time of the unassigned calls & drag & drop the assigned calls on the scheduler is taking more time to load, as we have used for loop function for binding the records.

To reduce the time taken we have used parellel.for threading concept but this is not applicable for the below functions.

=> scheduler.Appointments.Add(appointment)
=> scheduler.PerformLayout()
=> scheduler.Refresh()

It is a big problem for us, Can you please suggest if there a concept/method to reduce the loading time in the radscheduler? 

Video link mentioned below for your reference.

     Hi, I've been researching and trying to understand the custom filtering, but can't seem to understand it. I currently have a gridview with 5 columns.  I plan to have 4 text box and 1 dropdown that I want to use to filter the gridview.   I have tried the custom filtering from (https://www.telerik.com/videos/winforms/filtering-and-expressions-in-radgridview-for-winforms) but this is more on the style and doesn't hide the non-filtered rows.  I have tried to understand the custom filtering row in Demo application >> GridView >> Filtering >> Custom Filtering Row however, this is a bit too complicated with the usercontrols...  I've attached what my page looks like...  I can't seem to get the filtering on this page correct.  Can someone help?

Hi there,

I'm currently working on an application which needs an ImageColumn with two small checkboxes (without any text). The CheckState of the checkboxes is based on cell values. The clue is, that these cell values are hidden.
I've seen in your documentation and in a few other threads, that the override method SetContentCore is to set the content based on the row data. Unfortunately, I couldn't find anything to get the data from hidden cells in the current row.

1.protected override void SetContentCore(object value)
2.{
3.    this.RowElement.VisualCells ... // this contains only the visible cells
4.}

I'm wondering if it's possible to get the hidden cell values as well or if I could pass any data? One way I thought was to show the hidden cells, create my custom cell and then hide the cells again. But I think this is pretty ugly and I'm not even sure if it would work properly.

Is there any solution for this?

Kind Regards,
Roman

Hello:

In our validation forms, we like to preselect the currently choosen item. I have the code written for selecting the corresponding BindingSource.Position. This automatically selects the row. How can I force the GridView to scroll to the currently selected row?

Thanks,
Travis

It seems that I cannot display the exact sum of each group in the radGridView.

I want is to add the sum of the Column A group and the sum of the Column B group belonging to group A,

respectively, and the total at the bottom.

If I want to implement what I want C#, I want to know how to implement it.

I want you to show me how useful RadGridView is.

Please refer to my attached file.

This should be simple, I'm editing the data in the rows and I'd like those changes to be saved back to the database.

 

I have attached a screenshot to make it more clear.

 

In the screenshot i've circle my rows that i would edit and have its changes saved to database.

I'm using c# winforms, and my database is using microsoft SQL server

The below code throws an exception :  'Unable to cast object of type 'System.EventArgs' to type 'Telerik.WinControls.UI.Data.PositionChangedEventArgs'

RadTreeView1.LineStyle = TreeLineStyle.Dot

 

Any solution ?

Thanks for your attention.
