[Solved] Saving drag drop changes back to database

Hi,

We are using radtreeview to display data from multilple related tables. We have followed the example application at http://www.telerik.com/help/winforms/tree_datarelational.html. By following the steps data is correctly displayed. Further we need to save the changes made by drag drop back to database. What is the best way for doing this? On DragEnded I am trying to see the changes made to the underlying dataset but HasChanges() method when called in dataset returns false.

kindly, suggest me the way to achieve this.

Thanks,

Programmatically select a PageView page

I am migrating my code from using RadPanelBar to using RadPageView. In my code, I was able to select a given Panel by setting a boolean:

myRadPanelBarGroupElement.Expanded = true;

What is the equivalent call for a RadPageView page? I scrolled through all commands, and tried a few, and nothing worked. I admit I didn't try them all, though.

Any advice will be appreciated.

AppointmentInsert Missing

Hi,

I am working with a manually bound scheduler.

Once an appointment is added, deleted or changed I need to add or adjust the database. I can find the AppointmentDeleted event on the scheduler but cannot find either the appointment insert or update events. Reading through the forum it appears that this may have been made availalbe through some other method but I cant seem to to work it out.

I can see some reference to the Appointments.CollectionChanged event, but I can't see that either.

Can you please point me in the right direction?

Dynamic items added to start menu?

I'm trying to populate the right site of the start menu on the rad ribbon bar with recently access documents. I see how I can load items into there, but how do I handle the events for the clicks if they are being added at run time? Here is my code for adding an item:

Dim Item As New Telerik.WinControls.UI.RadMenuItem

Item.Name =

"TestItem"

Item.Text =

"This is a test menu item"

RadRibbonBar1.StartMenuRightColumnItems.Add(Item)

So now how do I programaticly handle the click even for that menu item? Usually I add a click handler through the visual studio IDE for items that already exist... Any help would be appreciated!

Chart Controls New to Telerik. Running Trail version

I'm new to Telerik controls. Two days back only I dowmloaded the control. I'm trying to create the report
I'm calling the Stored Procedure which will retrun Status Desc and the count
(Completed - 2 , Pending - 3 Inprocess - 5 Submitted - 10) I need to create the Chart to give overview of the status.

Dim

cmdSQL As SqlCommand = New SqlCommand("ExecutiveReportOverView", sqlcon)

cmdSQL.CommandType = CommandType.StoredProcedure

cmdSQL.Connection.Open()

Dim da As SqlDataAdapter = New SqlDataAdapter(cmdSQL)

Dim ds As DataSet

ds =

New DataSet

da.Fill(ds)

I tried the Following Statements for RadChart it doesn't work.

RadChart1.DataManager.DataSource = ds

RadChart1.DataManager.DataBind()

What should I do to get the values in the chart?

[Solved] Apply conditional formatting to another column

Hi,

I need to change the font colour of a cell value when I don't have access to CellElement (I understand that in the new version of the grid, this is a problem)

Is it possible to apply conditional formatting to a column based on the value of a different column?

For example:
If in Row 1, the value of Cell X = 123 then add a conditional formatting object to Cell Y

Thanks
Richard

AutoFilter Bug?

Hey guys,

Not sure if this is a bug or if I'm just doing something wrong.

I'm using a multiColumnComboBox with AutoFilter set to true.

Open the drop-down box (optional, see 3)
Type some text into the box.
Open the drop-down box (optiona, either 1 or 3 is same)
Select an entry with mouse or keyboard - same effect
Try to type new text into the box.

After step 5, my box is looking up for each individual character I type, and selecting the first entry on each return..

After step 5, if I open the box first and then type, the box will select and close after I hit a single character.

After step 5, if I hit the semicolon, no character will appear in the box - but the fiddly behaviour goes back to normal.

Not sure if this is to do with my code or not. Here's the section where I bind to the multiColumn:

                                        internal void FillDropDowns(bool bRefill)         
                                {         
                                    string sSuburbText = this.mcboSuburb.Text;         
                                    // string sTownText = this.cboTown.Text;         
                                 
                                    if (bRefill)         
                                    {         
                                        this.LocationsSentTo.Clear();         
                                        this.LocationsSentToTableAdapter.Fill(this.DataSet, "LocationsSentTo");         
                                    }

                                    {         
                                        FilterExpression filter = new FilterExpression(

                                            GridKnownFunction.Contains, GridFilterCellElement.ParameterName);

                                }         

Note that the FillDropDowns is not being called by any events while the typing or opening is taking place.
