Hello,

I have a problem getting my sort operation to work properly. I have set up a grid with viewstate disabled.
The grid is used for viewing only and all row-actions are done clientside, so no need for the grid to remember its data

I use custom paging and sorting and in the NeedDataSource event I supply the grid with data.
The LINQ query in that event also applies sorting. When i have viewstate enabled the SortCommand event is fired before the needdatasource, so i can determine the desired sorting and fetch the data all at once in the NeedDataSource event.

But when i disable the viewstate, the SortCommand event is fired after the NeedDataSource event. So i need to execute the LINQ query twice.

So my question is this
Is there any way to determine on posback/callback if the grid is going to fire the SortCommand? and can i use that info to passthe sorting info to the query in the NeedDataSource event implementation?
Or is there a way to force the SortCommand to be fired before NeedDataSource at all times?
When i try to intercept the NeedDataSource event and execute it after the sortcommand, i get no data.

I use 2009 Q2 for Ajax

Thanks

TextChange not fireing

Hi

I have a combobox that uses LoadOnDemand

<

telerik:RadComboBox ID="rcCostLocation" AutoPostBack="true" CausesValidation="false" SkinId="RadCombo" Runat="server"

DropDownWidth="318px" Height="190px" Width="318px" EmptyMessage="Please select" EnableLoadOnDemand="True"

DataValueField="Id" ShowMoreResultsBox="true">

</

telerik:RadComboBox>

If I click on a item in the list, the SelectIndexChanged and TextChanged fires okey, but if I clear the text from the DropDownBox and then click anywhere on my page, the default text "Please select" is shown but the TextChange even never fires.

I need to check if the user has cleared the text in the combobox and then disable another control on the page.
Any suggestions on how I can accomplice this ?

Regards
Per

same text, same editor, different html & different spacing

I'm using the "Paste from word" function and am running into a couple of issues. (see attached for screenshots)

1. sometimes the same line with a soft return in Word is generating an in the editor HTML and sometimes it's a . I've copied and pasted from Word from the same clipboard instance, in the same editor within the same session and seen different results.

2. when I do get the tags... sometimes that is rendered in the design view as no returns, one return, two returns or three returns. Togelling back and forth between design and HTML changes it until it settles at the one return and then it seems to hold consistently.

Grouping - where is the functionality ?

Hello,

I think that some functionality in RadListView is missing.

Regarding grouping. Where is that functionality ?

Why in the world I would like to group my products in pairs ? or by 3 - 4 items ?
I would expect to be able to set grouping expression here, then take advantage of group templates to create "report like" experience.

If would be really nice if we could achieve it.

Now, back to the Repeater :

pdf export problem

Hi,

while exporting to pdf, column alignment is not clear, the alignment always defaults to left for items and centre for headers.

GridItem[] dataItems = grid.MasterTableView.GetItems(GridItemType.Item);

                    // Apply some css style to the data items

                    foreach (GridItem item in dataItems)
                    {

                        foreach (TableCell cell in item.Cells)
                        {

                            cell.Style["text-align"] = "center";

                            cell.Style["vertical-align"] = "middle";



                        }

                    }
foreach (TableCell cell in headerItem.Cells)
                    {



                        cell.Style["text-align"] = "center";

                        cell.Style["vertical-align"] = "middle";



                    }

even i put the coding as like above, it does not affected the document,
actually i set ignore paging =true.If i set it as false, it is reflected the changes in pdf

But i have to set ignorepaging = true

please help me how to align the columns while exporting to pdf with setting ignorepaging = true.

Thanks for any help

RadTextBox not displayed in Asp.net

Hi everyone,
Perhaps someone could help me to find out why a RadTextBox is impossible to display in a acsx form.
Here is the code :

<

td> style="height: 50px; width: 614px;">

<telerik:RadTextBox ID="Objet" runat="server" Width="640px" Skin="Office2007" EnableViewState="False" />

I tried to display a simple <Textbox or an <asp:TextBox but nothing is displayed.
Other control like label, combobox or Radedit are working but no Text.
Last precision, the problem began since i bought the Telerik components, before this worked with free Radcontrol.

Thank you for your help.
Phil
