I am using an old version of RadGridView and from what I see the property EnableHeaderCheckBox properties not exist.

If there are any properties in an older version that I can use to implement select all by selecting column header.

Hi all,

How do you modify (or prevent) the display default "no data to display" text in when no line or column is yet set up ?

All forum answers are very old an do not work anymore, nor gridview.ShowNoDataText = false;

Thanks

Is there a quick was to find out if something has changed in the contents of a sheet?

Ideally, I would like an event 'Something Changed in Sheet', which I can use to, for example, highlight a 'save' control.

Really slow way would be to keep the contents of all cells, paint them, then respond, for each cell, to an event, compare the 'was' and 'is' values, and generate another event if they are different.

Before I do this, I'd just like to check that there isn't a simple way which I can't find.

Thanks

I have 2 grids with drag and drop capability, one of them is just a simple grid with 2 columns, the other grid is a grid with 3 Hierarchical Templates that have 3 associated BindingSources.

How can I, when dragging and dropping from the simple grid to the hierarchical grid, determine which Template I am dragging the row to and add it to that Template/BindingSources?

I used exactly the example code you have here (https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop), and indeed everything works.

I just wanted to understand if it's possible to know which Template the row is being dragged to and add it exactly to that Template.

I tried with scheduler but there is no agenda view maybe somehow with dayview and remove the hours?

I have a custom RadForm class that has inherited over a hundred forms. I have a custom RadTextBox class where I added some validation fired on the LostFocus event. To replace all RadTextBox controls with custom ones are a thousand controls to update, which are not an option.
I am looking for a way to maybe use events on my custom Radform which I can fire on Radtextbox control, it may be a way to update Radtextbox control to a custom one. Maybe other ideas on how I can use custom RadTextBox  control without updating one by one

I have a series of grids on a form, and all but the first one is created at runtime. Each grid has the same ValueChanged event handler attached to it. How can I tell which grid fired it?

private void ValueChanged(object sender, EventArgs e)
{

}

I tried intercepting the CellClick event (since that fires first) and getting the id from the tag property into a form-wide variable but that seems like a major kludge.

private async void CellClick(object sender, GridViewCellEventArgs e)
{
     myTag = (int)((MasterGridViewTemplate)e.Column.OwnerTemplate).Owner.Tag;
}

Any better ideas?

Thanks

I have made a Custom Summary grouper to show summary data "inline" with grouped rows, it will be great if something similar could be done native.

I attach project example if someone is interested

Is there a way, to get the RadCalendar to view similar to the calendar view in OUTLOOK.

This is what I am looking for:

I am using the radScheduler for the first time.  I am trying to bind some data to it (or even add events programmatically) that we are receiving from an RRS feed.   Is there a simple way to do this.  The Help files are more about binging a table/dataset to it.  Note, this control is used as a READ only view of events for my customers. 

TIA for the help
