Client side delete still shows item on postback

Hi,
I'm probably trying to do something that is achieved in a better way but this is what I'm trying to do.

I have a page with several controls and grids that is used for an edit for something else. The page is populated with data from a business object and certain properties are data bound. What I'm trying to do is making changes on the page and then hit a save button which will then postback and I'll read all the data from the controls and save in one hit.

The issue I have is the grid. I'm able to remove the items in the grid client side

function butConditionRemove_OnClick(grid) {

//grid is the clientid of the grid

var MyGrid = $find(grid);

var MasterTable = MyGrid.get_masterTableView();

var selectedRows = MasterTable.get_selectedItems();

for (var i = 0; i < selectedRows.length; i++) {

var row = selectedRows[i];

if (confirm("Are you sure you want to delete the selected entry?")) {

var table = MasterTable.get_element();

var rowtmp = table.rows[row.get_element().rowIndex]

table.deleteRow(row.get_element().rowIndex)

var dataItem = $find(rowtmp.id);

if (dataItem) {

dataItem.dispose();

Array.remove($find(grid).get_masterTableView()._dataItems, dataItem);

}

MyGrid.repaint();

}

This works fine but when I click on the save button which is just posting back the grid object on the server side still has the objects I have deleted in it. Other controls on the page which I'm changing as well have the updated values so it's just the grid that does not reflect the changes I make client side.

So is there a way I can make the grid pass it's client side state back in the same way other controls do.

RadRotator and RadGrid

I have a RadGrid on my page which pulls in an image name and a date related to the image.

I have also added a filter to the date field.

What I would like to do is have my Rotator display images from the RadGrid depending on what is shown.

So If someone filters the images by a date only those images will show in the RadRotator.

Is this at all possible and if so could someone help me out with a VB example preferably.

Thanks

Automatic Legend Generation for Different Series Types

I am using two different types of Chart Series in my chart i.e. "Bar" and "Line". The auto generated legend gives the same shape for both these series items (Circle,Square etc.) at a time. Is it possible to have the legends of similar shape as that of the series that they represent instead of a predefined shape? For example , for a series of type "Bar", can we get a legend in shape of bar and for "Line"a legend in shape of a line?

Chart (Obsolete)

Can you please update it ?

I could make a change for the firstline :

var panelbar = $find("<%= RadPanelBarUserInfo.ClientID %>");

But it failed for the second line:

var item = panelbar.FindItemByText("AccountInformation");

[Solved] Telerik controls and VS 2010

Hi,

I have ASP.NET AJAX Q3 2009 SP2 controls installed on my computer, and they're integrated with VS 2008.
Recently I installed VS 2010 (in addition to VS 2008). Do I need to install a new version of your controls to use them in VS 2010 or can I somehow convince the existing version to work with both environments?

I have a project that uses ASP.NET AJAX Q3 2009 SP2. I would like to move the project to VS 2010, but keep the same version of AJAX controls.

Tank you,
Andreja
