I have a grid with grouping enabled and also integrates a context menu to access editing and deleting of items. However, when the records are grouped, the index being returned is incorrect as it takes into account the grouping header rows. After a lot of research, I notice that all the examples in the forums use a different javascript method for the context menu than what is given in the Q1 2009 ASP.NET AJAX examples. The biggest difference is that the row index is retrieved using eventargs.get_itemIndexHierarchial(); So, I tried to implement this method to no avail. When implemented, that line of code actually errors and kicks the user out of the method.
I'm getting a bit frustrated by this and would love anyone's help.
Thanks
| Function RowContextMenu(sender, e) |
| { |
| var index = e.get_itemIndexHierarchical(); |
| document.getElementById("hdnGridClickedRowIndex").value = index; |
| var menu = <%= rmuContextMenu.ClientID %>; |
| menu.Show(e); |
| e.cancelBubble = true; |
| e.returnValue = false; |
| if (e.stopPropagation) |
| { |
| e.stopPropagation(); |
| e.preventDefault(); |
| } |
| this.SelectRow(this.Rows[index].Control, true); |
| } |

Hey all,
I am trying to make a single pie chart, my SQL table with the values for the chart will be only one row, with many columns that hold the data. However, when i add all the columns, it makes a whole bunch of pie charts with the value being 100%. How do i make this all one pie?

I'm trieng to get diffrent colors on diffrent groups.
Set's the color for all.. :-(
Is it possible to get "G 1" Red, "G 2" Blue and "G 3" Green.
| .rsHorizontalHeaderTable th |
| { |
| color: Pink !important |
| } |
| <div class="rsInnerFix" style="overflow:hidden;"> |
| <table class="rsHorizontalHeaderTable" cellpadding="0" cellspacing="0" border="0" style="height:25px;width:100%;"> |
| <tr> |
| <th>G 1</th><th>G 2</th><th>G 3</th> |
| </tr> |
| </table> |
| </div> |
I tried to change in the "OnResourceHeaderCreated" but without any luck.
The only way (not jet tested) that I have is to use jQuery to itterate over th in the table with class rsHorizontalHeaderTable...

Hi,
I am building my treeview in codebehind, with serverside callback. Some nodes contains ButtonLink with CommandName and CommandArgument filled (to allow richer node interaction).
Is there a way to create a "ItemCommand" event to handle the click on those ButtonLink ?
Thanks.

Hi, Telerik. I have a little problem. I'm trying to create a radgrid at runtime take definition of grid from a DB.
I haven't problem to show data, I'm able to create pop edit form but I'm not able to retrive modified data.
These is my code:
- this is ASCX code that define grid control
- This is the code behind that generate grid colums
in particular in this part of code we obtain the folowing error when evaluate this instruction:
e.Item.OwnerTableView.ExtractValuesFromItem(returnValue, editedItem)
Editor cannot be initialized for column: {our_field_name}
- In the end this is class for definition of template fields:
I wait for a response.
Thank you

If I have project which is using RadControls for .Net 2.0 before, what is the migration steps to use the controls for .Net 3.5?
- are all API functions identical between those two sets of controls?
Another question is what are the features differences between those two set of controls besides my list below?

Hello,
I would like to control with a slider a kind of chain. I would like to place a number of div-elements from left to right. Each div contain a picuture and a link and text. With the slider I want to be able to slide the different divs along the chain. Lets assumme the chain will contain 6 divs then i want to be able to see 3 of them on one time. I want to see div1, div2, div3. If i slide to the right i would like to see div2, div3, div4 and so one. Deepending on the zoom level I also want to be able to see more or less then 3 div-elements.
I need a div-element because i want to change the background color of the different div-element according to events.
Does anyone have an idea how I can develop such a control?
I appreciate every help.
Cheers
Chris

Hi,
My upload control is located inside of an AjaxPanel, so I use the ConditionalPostback method.
When the user selects a file, I want it to immediately upload - how do I do this?
I presume I must use the OnClientFileSelected call, but I dunno where to go from here.
Thanks!
Morten
