Hi,

I am grouping a ListView in DetailsView on a databound DateTime column. I can format the CellElement.Text for the column using the cell formatting event:



But how can I format the group header to display the long date format as well?

Dear Sir/Madam,

1)How to Manage Rad from  on Tile click event Not user control as In DemoHub?

2)How to show sub tiles on Tile click event?
[When clicking a Tile 1 from Group 1 want to show All Tiles from Group 2 at same Location may contain more Tiles or less]

Thank You,
Dipan

Hi,

I'm working on an application in WinForms which uses a RadGridView to display information.
I have run "out of space" and want to display further information as tooltip.
When I databind the grid, I place this information in a column with Visible=false.

I have tried two ways withoug success.
First I tried he CellFormatting event as described in the Help Section on www.telerik.com.
I only want to display the tooltip, if there is information to show (FieldB is in the hidden column), but I get values everywhere, and the values are often wrong.

Then I tried to do it manually by using the DataBindingComplete and the CurrentCell property also described in the Help Section on www.telerik.com.
  My problem is that CurentCell is always null.

I hope you can help me how to do this.


Best regards
Henning

Hello,

Trying to catch the 'SortChanging' event.

My first guess is that in GridViewCollectionChangingEventArgs
.NewItems, I'm going to fing the new 'SortDescriptor', and in GridViewCollectionChangingEventArgs
.OldItems

But I see that the behavior is different from what I exepected

Initial state: the gridview is not sorted.
Action : I click on the column titles.

1° Click on columne A : First time, the grid is not sorted, in NewItems, I find one 'new item' corresponding to what expected.
 NewItems : A Ascending; [as expected]
 OldItems : null; [as expected]
2° I click on the same column again
 NewItems : A descending; [as expected]
 OldItems : A descending; [not as expected : I expected A Ascending]
3° I click on another column
 NewItems : A descending; [not as expected : I expected B something]
 OldItems : A descending; [as expected]

(NewItems and OldItems are always = 1.)

Which means that I can when changing sort, I can not distinguinshed what exactly has changed from the EventArgs.

Or am I not doing this the right way ?

Thank you for your help.



And in case here the code I'm using to test it right now:

            object o;
            SortDescriptor newSortDescriptor, oldSortDescriptor;
            string newItemString, oldItemString;

            for (int i = 0; i < e.NewItems.Count; i++)
            {
                o = e.NewItems[i];
                if(o.GetType().Equals(typeof(SortDescriptor))) {
                    newSortDescriptor = (SortDescriptor)o;
                    newItemString = newSortDescriptor.PropertyName + ' ' + newSortDescriptor.Direction;
                }
                
            }

            for (int i = 0; i < e.OldItems.Count; i++)
            {
                o = e.OldItems[i];
                if (o.GetType().Equals(typeof(SortDescriptor)))
                {
                    oldSortDescriptor = (SortDescriptor)o;
                    oldItemString = oldSortDescriptor.PropertyName + ' ' + oldSortDescriptor.Direction;
                }
            }

Hello Team
i have a table with 2 columns  
FieldName       FieldValue
                                                

AD	12.01
AD	13.01
AD	14.01
AD	15.01
BD	23.01
BD	24.01
BD	25.01
BD	26.01
CD	27.01
CD	28.01
CD	29.01
CD	30.01
DD	27.01
DD	28.01
DD	29.01
DD	30.01
Main	10
Main	20
Main	30
Main	40

from the above table i need to create  a pivot table structure like

MAIN	AD	BD	CD	DD
10	23.01	27.01	27.01	12.01
20	24.01	28.01	28.01	13.01
30	25.01	29.01	29.01	14.01
40	26.01	30.01	30.01	15.01

and from here i need to generate a line chart with series MAIN vs AD
                                                                                          MAIN vs BD
                                                                                          BD     vs CD
                                                                                          AD     vs  DD

all the data values are in double datatype

there are some thousands of records in the table more than 100,000 records

i dont want to create a for loop for each series addind and (x,y) insertion to it

is there any possibility to add datacolumns as x,y axis in line chart from datatble,????

for example for the above example X axis is MAIN column and Y-Axis is AD column for series-1
something like fastest way, of binding datacolumns to chart Axes

Please suggest

 

Hi
I have a problem in filter of radmulticolumnCombobox .
when i used this code for filter in radmulticolumn ، I have a error (invalid expression filter ).

MulCmb.EditorControl.FilterDescriptors.Add(Id, FilterOperator.StartsWith, 0);
But if i uesed this code ، i don't have problem .

MulCmb.EditorControl.FilterDescriptors.Add(Id, FilterOperator.IsGreaterThanOrEqualTo, 0);

But I must used FilterOperator.StartsWith.
How can i fix this problem?
Could you help me?

 

I'm working my way through a problem and am trying to understand the flow of creating or updating a row.

I have a test app with a RadGridView that displays hierarchical data based on 2 related datatables. The form has 3 buttons: Add Parent Row, Add Child Row, Modify Parent Row.

As near as I can tell, adding a parent row fires a CreateRowInfo event, followed by a RowValidated event. On the CreateRowInfo event, there is no data in the cells, their values are all null until I get to the RowValidatedEvent.

However, modifying the parent row causes a CreateRowInfo event, but not a ValidateRow. Checking inside the CreateRowInfo event, the cell values are still all null, so where/when are these values being loaded?

Is there a quick way to center groups similar to the attached picture? Or do i have to do the calculations manually in the resize event?

I have gridview also binded  with DataTable. In the end of the right side, i have a pencil image to edit  By default the gridview will not allow Editing.




If i click the pencil image then the row should allow editing (that selected row only).

How to do this?

How to enable editing for the current row?

Thanks
