Hide duplicate values /repetitions in (hierachy) grid

Hey folks,

I figure if there is any way to hide repeated cell values in my grid. I attached a screenshot and want to hide the redundant information in the first 3 columns. I am wondering if there might be an intelligent way of doing with the grid control.

Has anybody of you guys a cool idea to me?

I attached a screenshot which shows my actual grid and a grid which looks like it should be.
At this moment I do not have any idea except of iterating thorugh the rows. Additonally the difficulty is that this is a hierachy grid which is bound to the childtemplate by the first thre rows. So the best way should be formatting the cells with the fore color white, right?

Any thought?! ;)

Thanks in advance.

Best

How to expand specific group in code?

Hi,

I have hierarchical RadGridView where MasterGridViewTemplate.AutoExpandGroups is set to False. Code for binding is like this.

                    PatientGridView.DataSource = currentPatientList;         
            GridGroupByExpression patientExpression = new GridGroupByExpression();         
            patientExpression.Expression = "FullName as FullName format \"{1}\" Group By OrderID";         
            PatientGridView.MasterGridViewTemplate.GroupByExpressions.Add(patientExpression);         

After binding I want to programatically expand some groups by certain condition. I have tried with following code but it doesn't work:

                                foreach (GridViewRowInfo row in PatientGridView.Rows) {         
                            if (someCondition == true) {         
                                row.IsExpanded = true;         
                                row.IsSelected = true;         
                                PatientGridView.GridNavigator.SelectRow(row);         
                            }         
                        }         

Can you advise how to programmatically expand specific group in RadGridView where all groups are collapsed by default?

Regards,

Tomislav

upgrade problems

I've migrated a winform project to the 2009.3.9.1203 version of your controls and I have several issues:

- I can't open a form in VS designer, it says:
System.InvalidCastException: Unable to cast object of type 'Telerik.Charting.Styles.Unit' to type 'Telerik.Charting.Styles.Unit'.
The error occurs with these lines:

chartMarginsTitle1.Bottom = ((Telerik.Charting.Styles.

Unit)(resources.GetObject("chartMarginsTitle1.Bottom")));

- my RadGrids lose their Size property, their width takes big big values, and I need to reset them manually....

Unable to select entire row when checked the checkbox of that row

Hi All,
I have check boxes in the gridview for each row. When i checked a particular row's checkbox the enrire row should be selected. It is working but when i checked another checkbox, the previous checked row is not selecting. Only current row is selected. I need to select all the rows which i have checked.

I tried in this way,

private void GridView_MouseUp(object sender, MouseEventArgs e)

{

for

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

{
if (GridView.Rows[i].Cells["chk"].Selected == true) //CellElement.RowInfo.IsSelected)

{

//GridView.Rows[i].Cells["chk"].RowInfo.IsSelected = true;
GridView.Rows[i].Cells["chk"].CellElement.RowElement.IsSelected = true;

}

else //if (Convert.ToBoolean(GridView.Rows[i].Cells["chk"].RowInfo.IsSelected))

{

//GridView.Rows[i].Cells["chk"].RowInfo.IsSelected = false;

GridView.Rows[i].Cells[

"chk"].CellElement.RowElement.IsSelected = false;

}

}

i tried with mousedown and mouse click also. It is not working.
note: The checkbox column is added to grid programatically.

"The operation completed successfully" exception

I'm getting an exception in a RadForm based class with the following call stack:

The operation completed successfully
   at System.Drawing.BufferedGraphicsContext.CreateCompatibleDIB(IntPtr hdc, IntPtr hpal, Int32 ulWidth, Int32 ulHeight, IntPtr& ppvBits)
   at System.Drawing.BufferedGraphicsContext.CreateBuffer(IntPtr src, Int32 offsetX, Int32 offsetY, Int32 width, Int32 height)
   at System.Drawing.BufferedGraphicsContext.AllocBuffer(Graphics targetGraphics, IntPtr targetDC, Rectangle targetRectangle)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

BackgroundWnd is a very simple window that just shows a solid background color. It is based on RadForm. Unfortunately, I can't provide a simple code sample to make this happen. It can occur after many hours of operation doing lots of different things. I found the following discussion on this type of error:

http://nomagichere.blogspot.com/2008/03/systemcomponentmodelwin32exception-is.html

However, I don't know if it's applicable. I couldn't find a call to CreateGraphics in your source code in the RadForm project. I don't call CreateGraphics in my code either. Have you seen this issue before or have any idea what could cause it (or fix it)?

Dynamically add and select ribbon bar tab problem

I am building an MDI application, in which i want to add tabs specific to the active mdi window to the ribbonbar.
I got this working by capturing the window's activated event. When a window is activated it removes the tabs associated with the previous active window, and adds new tabs which are associated with the new window. After the new tab(s) are added I activate one by using the tab.IsSelected property.

This works, however for some reason the title of the tab isn't highlighted if i switch between MDI windows.
For example, I open a window which lists orders for example. The associated tab gets added, selected, and is properly highlighted. If I then click on an order, it opens a detail window. The detail window gets activated, so the tab associated with the "order list" window gets removed, and a new tab gets added. Again, the tab is properly added, selected and highlighted. If i now select the "order list" window again, the "order detail" tab gets removed, the "order list" tab is added, and gets selected. However, for some reason it doesn't highlight the tab title.

Any ideas what might be causing this peculiar behaviour? As far as i know i'm not capturing "lost focus" events which might cause problems.
