If I have a RADGrid, such as:

                            <telerik:RadGrid runat="server" ID="radGrid" PageSize="25"         
                        AllowPaging="true"          
                        AllowSorting="true"          
                        AutoGenerateColumns="false" >         
                        <PagerStyle Mode="NextPrevNumericAndAdvanced" />         
                        <MasterTableView>         
                            <Columns>         
                                <telerik:GridBoundColumn DataField="ItemNumber" HeaderText="Item number" AllowSorting="true"  />         
                                <telerik:GridBoundColumn DataField="Name" HeaderText="Name" />         
                                <telerik:GridBoundColumn DataField="ShortDescription" HeaderText="Description" />         
                                <telerik:GridBoundColumn DataField="Price" HeaderText="Price" />         
                            </Columns>         
                        </MasterTableView>         
                    </telerik:RadGrid>         

What is the preferred way to localize the HeaderText values ? (Say, if the page is being shown in the Danish culture, I would like to display the danish names as column headers, instead of english ones).

I possible, I would like to do this in the markup. I already have a helper method such as:

                    HeaderText="<%= Translate.Text("ItemNumber") %>"         

But if I try to do this on a Column, I get a parser error: "Literal content ('<telerik:GridBoundColumn DataField="ItemNumber" HeaderText="') is not allowed within a 'Telerik.Web.UI.GridColumnCollection'."

Telerik radGrid demos: Is there any reason you don't explicitly disable vewState for every control in the editTemplate?

q2 2009

hiya,

I can't see any reason why you wouldn't explicitly disable viewstate for every control in a radGrid's editTemplate in the demos.
Let me know if there is a good reason, otherwise, disable it in your demos, the performance will benefit.

If this helps, you know who to credit the points to....

filtering options customizable

Hi,
Please could you tell me if the fitlering buttons are customizable (i.e. can you just show a subset of them and can you rename the options)

Thanx

Suppress ClientEvents on Page_Load

Hello!

I have an ASP.NET-Button shipped with VS. This button is responsible for saving the data the user enters in the form. When the Page is loaded, the button should be disabled. Then I have other controls (standard VS controls), where I have "linked" the client-side onpropertychange() event. When a user for example fills out a javascript-enabled textbox, the javascript-function will enable the Save-Button. Everything is fine.

When I now - for example - use RadTextBox and link the ClientEvents-OnValueChanged with the same javascript-function, the page loads and I can see, that the Save-Button is automatically enabled?!?

Is it possible, that RadControls do not fire javascript-events on Page_Load? Are there any workarounds?

Bye

Michael

RadGrid row events

Hi,

Using the ajaxManager.ajaxRequest method within javascript, is there any way to pass to the server details of the current GridEditFormItem that is the container for the control triggering the postback?

For example one of the sequences of logic requires that if a date in a RadDateTimePicker changes, a routine will pass that date, another date from a further datetimepicker, a reference to an image control and a reference to a combo box to the server. On the server the information from the two dates and the combo box will then determine what image is displayed in the image control.

Now the simplest way of managing this is to grab the GridEditFormItem and get the server to act on that, then I can easily reference it's controls using the FindControl methods.

Been on this page all day and have made great progress but am hitting a brick wall now I'm on the final stage :(

Any help would be greatly appreciated.

Best Regards,

Jon

Window / Java applet

Hi Telerik-Team,

I have two RadWindow add to an RadWindoManager.

First I open a window to show some stuff. On this window you can open another window
thats partly overlayed on the first. THis window shows a java applet (grafic / MAP24TP Routing).

On IE there isn't a probelm. But on Firefox 3.x the content of the second window
will only shown if you move the window out of overlaying the first window. Then the content
is shown correctly or partly.

I habe added a jpg that shows the problem.
Whats the solution for that?

Thanks alot
CHrisitan
