Hi, I am having problems with getting page sizes reasonable and I would love some input from experienced developers.

Just as an example, I converted an old asp page which displayed data pulled from a database in a small table. The table, plus a static menu, came to 32,455 bytes.

Now I have converted the identical data, but using RadMenu and RadDatagrid. The pages look and function nearly identically (Ok, the rad page looks better) but the size is now 435,873 bytes. That's more than a 10 fold increase in size to make things look prettier. Am I missing something here? Many of my clients are in third world countries and don't have hi speed internet connections. I really need to keep my pages below 200,000 bytes.

Some of the more complex pages using Rad controls are approaching 1 MB, and I don't have pictures on them.

Is there a way of reducing the page size?

I can't seem to find a way to cache the radMenu, which appears on every page (it is in the MasterPage). Because the MasterPage is merged with the other content each time then it is not cached on the client side, so it takes seconds to load each time.

Has anyone found a way to cache the navigation menus (RadMenu)? I guess if I used frames (god forbid going back to ancient history) then I could cache the RadMenu.

I would really appreciate some tips and thoughts from those developing real applications that need to perform.

Do people think that a 500,000 bytes + size page is fine? Am I too old school?

Cheers

Ian.

Hi all:

I have a custom control inside Sitefinity that implements the RadScheduler.  When the page loads, it shows correctly, but when I try to change the selected date, I get this error:

Server Error in '/SiteFinity' Application. DataKeyField, DataSubjectField, DataStartField and DataEndField are required for databinding

This properties are setted in the code behind.  This is the code I used:


And the code behind is 


What's wrong?

HI,

I need to display confirm box (With option ok/cancel) when user clicks on Cancel button inside an edit or insert form.
We are adding edit button in the grid as following :

<

 

 

telerik:GridButtonColumn UniqueName="btnEdit" CommandName="Edit" Text="Edit" ButtonType="PushButton"

 

 

 

Visible="false">

We tried using oncommand and writing some javascript code but that is not an option.
It interferes with required field validators.

The cancel button is autogenerated and we are not writing any code for it.

Please suggest something as it is an urgent requirement.

 

I need copy onkesspress event of txtName the value on txtHumanLabel when user update or insert.


I did this, but does not work

  var txtEditId = $telerik.$(masterTable.get_element()).find('input[id*="txtEId"]')[0];   --IS UPDATE??

                if (txtEditId == undefined) {
                    var txtHeader = $telerik.$(masterTable.get_element()).find('input[id*="txtHeader"]')[0];  -- IS INSERT
                    txtHeader.value = Name.value;
                   
                } else {

                    var txtHeader = $telerik.$(masterTable.get_element()).find('input[id*="txtHeader"]')[0];
                    var value = txtHeader.value;
                    if (value.length == 0) {
                        txtHeader.value = Name.value;
                    }
                }

Hi,

I have four listbox. Three of them contains items that could be transferred to the other. Users change the visible listbox with a radio button. Each listbox contains a different template item, so my listbox that receive items can't have a template item. I've try the client-side transfer mode but it's doesn't transfer the item completly; my item is display is plain text, without any html code. I've seen in the help documentation (http://www.telerik.com/help/aspnet-ajax/listbox-templates-overview.html) that I can't transfer template in client-side mode, only on server-side. I can't use transfer button between the listbox because we want the user to do one-click only to transfer one item, and not select and item and click on the button. I can't put a button element in each item because it will trigger an exception (ThrowIfMaxHttpCollectionKeysExceeded). Presently, I try to simulate a button with a div element, but I can't put an id in my item template because an id have to be unique in a HTML page, so I can't put an function assigned to this div...

Exemple of a listbox:


My question is: how can I transfer an item from one listbox to another, with the item template, without using the transfer button, with a div element (or any other html element that is not an input element) that play the button role in each item?

Thank you

Hi guys. I'm just trying to get the simple export feature to work. I like the demo sample here (Export Demo) where the grid has the export buttons built in. I was able to get the buttons to show up in the grid, however, when they are clicked on, nothing happens. (Well, the data seems to be refreshed against the object data source, which isn't what I want to happen...but I guess that's a separate issue) I've tried it in two different browsers and it doesn't seem to be blocked by pop-up blockers. Is there something I'm missing?

Thanks!

I have a tabstrib and multiview.   Each Pageview ahs a seperate user control.  Several have radgrid on them with an edit column.   When the user clicks edit.  the page postbacks and after the page refreshes the control for multiview with tabindex of 0 is displayed.   TO get back to original tab you need to click another tab then back to originating tab with radgird.   When it is displayed,  the tab is blank.   WHat do I need to do to get the edit to work?

I have a column which contains a date, but I need to return it from my C# model as string so that i can do some special formatting to it first (I need to check for null and for DateTime.Min and then return an empty string in those instances). If it's a string, however, I understand that the sorting won't work correctly. Is there a way to set the data type of the column to DateTime or to get the string date to sort correctly?

Thanks,
Jay

Hi!

I want to localize pager buttons(first,,prev,next,last) in NextPrevAndNumeric pagermode.

In Grid itemCreated I can access GridPagerItem., but I don't know how to access to these buttons.
I have already tried to set localized text in the radGrid.PagerStyle, but it isn't works.

Thx.
