Validating Cell Values with color changes

Hi,

I am using a datagrid in which all editable columns are shown in a different color which i am doing on cell formatting , however when data is entered in cells which is invalid i want to change the back color to Red .

Here i want to make sure that user is taken back to cell in which he was doing editing also when the value he has enetred is correct the back color should change back to editable back color.

Also can't we show errortext in cell directly rather then showing it on grid.

Thanks
Anuj

Auto Hide Docking Panel Min Width

Hello

I have a docking manager with 2 panels. one fixed and one auto hide.
When the auto hide panel is activated I want it to open the full width of the docking manager but at the moment it only opens a 1/4 (ish) the way.
I have tried setting the "minimumsize" and the "minsize" and the "size" attribute but none of them seem to make any difference, although I cannot find any documentation on the "minsize" attrib.

Is it possible to do this?

Thanks

Complete Outlook Style with Expand & Collapse style

Hello,
I am searching to reproduce the outlook pane style in my application. In the radcontrols for winforms I found the panelbar which can be used as outlook bar when the group style is set to OutlookNavPane. It's almost like the official outlook bar.
But I didn't see the button wich allows to collapse the panelbar to a minimal state (icons still visible on the left...)

Can you tell me please If the PanelBar control allows that ? I absolutely need this functionnality..

Thank you

Panelbar (obsolete as of Q2 2010)

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.
