How can i check while treeview node is editing if one of the keys (< > ? * | " / \ ) is pressed?
And in case that one of the keys is pressed how can i cancel edit?

Also it seems that treeview_ValueChanging event is not raised for couple of these characters.

Thanks,
Vladan

[Solved] New version - Can't find old functionality

I just upgraded to 2010 Q2 SP1 and most of my code I have been able to upgrade. The main problem is getting at the Cell's underlying control now that cellelement is gone:

For Each CheckRow In gvData.Rows

If (Not (CheckRow.Cells(5).CellElement Is Nothing)) Then

Dim CheckCell As RadCheckBoxEditorElement = TryCast(CheckRow.Cells(5).CellElement.Children(0), RadCheckBoxEditorElement)

CheckCell.UseDefaultDisabledPaint =

True

CheckCell.Enabled = False

End If

Checkbox column in gridview

Hello,

Am using windows, vb.net
I have checkboxcolumn in Radgridview. Am displaying BIT field from database which is displayed as checkbox in gridview in 3rd column, and first & second columns values cannot be edited.
I have the following problems;

Only one checkbox has to be check at a time. If i select a check box then previously selected check box has to uncheck.
If i press down or up arrow key, then check state of the check box has to be changed.

It's an urgent requirement, awaiting for the team to help me

Thanx

potentially serious bug in SP1

I have opened a ticket up for the following issue. I am posting it here in the forum to see if others have experienced the same problem.

After upgrading to Q2 SP1, I found that I can no longer "click to add new row" in the child's template of a bound hierarchy data grid without the error message "an entry already exists with that key". The key column is the primary key with an auto-increment property. If there is no hierarchy and only a top level data grid then the click to add a new row it does seem to work okay. However in the children templates it gives that error right away or after adding one row.

I attached the project that Stefan had sent me on the last ticket open. you can try to add new rows to the products table. I used the Northwind database from the examples folder. The only change I made was to make the primary key not a read-only field so that I can try to manually enter a value to see if that would work, which it didn't. Please let me know if you experience the same thing. If so, is there some workarounds? Being able to add new rows to the data grid is obviously pretty basic stuff and my application relies on it heavily.

Thanks,

Eyal

radscheduler Q2sp1 labels not appearing on appointments in month and timeline view

I am curently working on a winforms promotions module and i am using the scheduler control to display all the promotions that are occuring on certain dates for all our locations. The appointments are added to the control when the form that the control belongs to loads.

my code for creating the appointments is as follows

private void getAppointments()

{

radScheduler1.Appointments.Clear();

try

{

DataTable getPromoDates = getPromoTab.Tables["PROMOTION_ADVICE_HEADERS"].Copy();

DataTable getPromoColours = getPromoTab.Tables["PROMOTION_TYPES"].Copy();

for (int i = 0; i < getPromoDates.Rows.Count; i++)

{

Appointment myAppoint = new Appointment((DateTime)getPromoDates.Rows[i]["START_DATE"], (DateTime)getPromoDates.Rows[i]["END_DATE"

]); 

//the summary of the appointment is the promo tables primary key

myAppoint.Summary = getPromoDates.Rows[i]["PA_ID"].ToString();

try

{

                       //lookup the promo type and set the background of the appointment (custom backgrounds are defined elsewhere)

int getColour = int.Parse(getPromoDates.Rows[i]["PROMO_TYPE"].ToString());

var getBackCol = from o in getPromoColours.AsEnumerable() where int.Parse(o.Field<decimal>("PT_ID").ToString()) == getColour select new { colourNum = o.Field<decimal>("COLOR_ID") };

myAppoint.BackgroundId = int.Parse(getBackCol.ElementAt(0).colourNum.ToString());

}

catch (FormatException ex)

{

myAppoint.BackgroundId = 99;

}

string isprocessed = "Finalised";

if (getPromoDates.Rows[i]["Processed"].ToString() == "N")

{

isprocessed = "Open";

}

myAppoint.Visible = true;

//set the location attribute of the appointment to some meaningful string describing aspects of the promotion

myAppoint.Location = getPromoDates.Rows[i]["DESCRIPTION"].ToString() + " - " + ((DateTime)getPromoDates.Rows[i]["START_DATE"]).ToShortDateString() + " - " + ((DateTime)getPromoDates.Rows[i]["END_DATE"]).ToShortDateString();

myAppoint.Location = myAppoint.Location + " " + isprocessed;

myAppoint.Description = myAppoint.Location;

radScheduler1.Appointments.Add(myAppoint);

}

radScheduler1.AutoSize = true;

radScheduler1.BackColor = Color.LemonChiffon;

radScheduler1.Update();

radToolStripLabelElement2.Text = radScheduler1.ActiveView.StartDate.ToLongDateString() + " - " + radScheduler1.ActiveView.EndDate.ToLongDateString();

}

catch (Exception ex)

{

}
radScheduler1.ActiveViewType = SchedulerViewType.Month;


// radScheduler1.ActiveViewType = SchedulerViewType.Week;
 


 

 

SchedulerMonthView myMonthView = new SchedulerMonthView(DateTime.Now, true);
 
myMonthView.EnableWeeksHeader = 

 

false;
 
myMonthView.WeekCount = 1;
myMonthView.HeaderFormat = 

 

"dd-MM-yyyy";
 
myMonthView.ShowHeader = 

 

true;
 
myMonthView.ShowWeeksHeader = 

 

false;
 
radScheduler1.ShowAppointmentStatus = 

 

true;
 
 
 

 

//myAppoint.Location
 


 

 

//SchedulerWeekView myMonthView = new SchedulerWeekView();
 


 
radScheduler1.ActiveView = myMonthView;
 
radToolStripLabelElement1.Text = 

 

" ".PadRight(400, ' ');
 
radToolStripLabelElement2.Text = radScheduler1.ActiveView.StartDate.ToLongDateString() + 

 

" - " + radScheduler1.ActiveView.EndDate.ToLongDateString();
 
radScheduler1.Width = 

 

this.Width - 10;
 
radScheduler1.Height = 

 

this.Height - radToolStrip1.Height - 15 - radDateTimePicker1.Height;
 
radSplitContainer1.Width = 

 

this.Width - 10;
 
radSplitContainer1.Height = 

 

this.Height - radToolStrip1.Height - 15 - radDateTimePicker1.Height;
 
radGridView1.Width = 

 

this.Width - 20;

}

So when i run this program, the appointents are created correctly with the right background colours but the appointments have no labels. See attached screenshot. capture.png. The exact same code on 2010Q2 produced screenshot capture2.png.
Any ideas on how i can fix this? Also i could prefer to use the timeline view, the reason i used the month view was because in the Q1 release, i had the same issue as described above, but the monthview labeling worked but the timeline view didnt.

Deserializing and new/removed dockpanels

Hi,

I'm using SaveXML and LoadXML to restore the layout of dockpanels. Let's say we release version 1 of our application with 2 dockpanels. In version 2 we need 3 dockpanels but using LoadXML will only load the 2 dockpanels from version 1. Also if we remove a dockpanel from version 1 it will still show up in version 2.

Is there a way to make the LoadXML NOT overload new/removed dockpanels?

Thanks,
Brian

Show full datetime in column but group by date only

I'm using a databound gridview, binding to a custom list of "entity" type. The datetime field I want to group by is called Created.

public partial class frmSearchResults : Form

{

private List<Entity> Results;

public frmSearchResults(List<Entity> SearchResults)

{

InitializeComponent();

Results = SearchResults;

gridSearchResults.DataSource = Results;

gridSearchResults.BestFitColumns();

}

I've found some related posts in the forum but none have solved my issue yet (I'm new to rad controls so I may very well be missing or misunderstanding something). One post mentioned CellTemplates but I'm not sure to go about that and that solution was in the context of a non bound grid.

Thanks,
John

[Solved] Is each ScreenTip cached?

Hi,

I have a GridView and when someone hovers over a cell a ScreenTip is displayed with some more informations. Works good, but now there was a need to add a button where the user can turn off these ScreenTips. And surprisingly even after turning them of some ScreenTips are still getting displayed. For us it seems that all ScreenTips which have been already displayed seems to get displayed without calling the ScreenTipNeeded Event.

How can I change this behaviour?

Thanks,
Michael
