[Solved] OnValueChanged Cancel

Going crazy here:
I am trying to validate a dynamically created RadNumericInput box. I have wired the OnValueCHanged event as follows:

newControl.ClientEvents.OnValueChanged = "CheckAllocation"

I have a javascript routine as follows (stripped down for example):

function CheckAllocation(sender, eventArgs) {

...(do some checking and if number not good then...)

sender.set_value(eventArgs.get_oldValue());
    eventArgs.set_cancel(true);
     sender.focus();
    return false;
    }

I simply want to put the old value back in the box and return focus to the sender. The event fires fine and code seems to run, but the focus goes to wherever I clicked, and when I put the old value back in the box it fires OnValueChanged event again...

Is there something I am missing? This seems like it should be pretty simple...

Many Thanks
Ford

An issue with the XAxis.DataLabelsColumn

I have a chart that uses a sql stored procedure as a data source.
The issue that i'm having is that I can't seem to set the X Axis DataLabelsColumn.

It seems stuck on just a generic 1,2,3,4,5,6,7.....etc.
I'm using the following line:
RadChart1.PlotArea.XAxis.DataLabelsColumn = "Column1"
with Column1 being a column in the sql stored procedure data results.
It doesn't work.
Is there something that I'm missing or doing wrong? Should i be using a "SELECT statement" rather than a stored procedure?
Thanks.

[Solved] RadGrid vs GridView

I am trying to convert a standard asp.net GridView to a RadGrid.

My set up is Windows XP Pro SP3, ASP.NET AJAX controls 2009 Q1 and Visual Studio 2008 3.5 Framework.

In the GridView I have code that will allow me to edit/update/cancel a record.

Please see below the asp.net code with standard GridView

                    protected void Page_Load(object sender, EventArgs e)         
                {         
                    //Load the categories grid only the first tim the page is loaded         
                    if (!IsPostBack)         
                    {         
                        //Load the categories grid         
                        BindGrid();         
                     
                    }         
                }         
                     
                //Populate the GrdView with data         
                private void BindGrid()         
                {         
                    //Get category from query string         
                    string categoryId = Request.QueryString["CategoryID"];         
                     
                    //Get a DataTable object containing the categories         
                    grid.DataSource = CatalogAccess.CatalogGetCategories();         
                     
                    //Bind the data to the grid         
                    grid.DataBind();         
                }         
                     
                //Enter row into edit mode         
                protected void grid_RowEditing(object sender, GridViewEditEventArgs e)         
                {         
                    //set the row for which to enale edit mode         
                    grid.EditIndex = e.NewEditIndex;         
                     
                    //set status message         
                    statusLabel.Text = "Editing row " + e.NewEditIndex.ToString();         
                     
                    //Reload the grid         
                    BindGrid();         
                } 
            
                    

                    protected void grid_RowUpdating(object sender, GridViewUpdateEventArgs e)         
                {         
                    //retrieve the updated data         
                    string id = grid.DataKeys[e.RowIndex].Value.ToString();         
                    string name = ((TextBox)grid.Rows[e.RowIndex].Cells[0].Controls[0]).Text;         
                    string description = ((TextBox)grid.Rows[e.RowIndex].FindControl("descriptionTextBox")).Text;         
                     
                    //execute the update command         
                    bool success = CatalogAccess.UpdateCategory(id, name, description);         
                     
                    //cancel edit mode         
                    grid.EditIndex = -1;         
                     
                    //display status message         
                    statusLabel.Text = success ? "Update successful" : "Update failed";         
                     
                    //reload the grid         
                    BindGrid();         
                     
                }         
                     

Is there a way to achieve the same thing with the RadGrid? I would appreciate it if anyone could point me in the right direction.

Many thanks

Simon

RadAjaxManager: MANY TO ONE Controls Issue

I have MANY controls on a page that can UPDATE one control, but it will only do one!

This is a sample code:

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" />

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1" >

<telerik:AjaxSetting AjaxControlID="btnBack">

<telerik:AjaxUpdatedControl ControlID="tp"/>

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="btnForward">

<telerik:AjaxUpdatedControl ControlID="tp"/>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Why is it that only the top control works but the Manager ignores the other?

Thanks

Client-side expand after postback shows nothing

After a postback, I expand the splitter to show the top pane and it's blank. I inspected the markup and see that the width and height of the top pane are 0px. This only seems to happen after a postback has occurred. Has anyone else encountered this?

Right align a single RadMenuItem

not sure if I'm missing something obvious here - but is there a way to right align a single menu item?
Basically I have a 100% width menu - where I want most of the menu items to appear normally (aligned to the left) but the last item (a logoff button) to always appear at the right side (end) of the menu.

Possible?

Ajax request not being fired

I have a simple page with a listbox and two buttons. I use a RadAjaxManager and an RadAjaxPanel. I have tried setting the manager to handle the panel requests and I have tried using to the panel itself to handle the ajax requests. Neither method will raise the OnRequestStart event when I click a button and handle the buttons click event.

I have this working in plenty of other places. I cant seem to determine why in this case it is not working. Functionally, they are identical.

any ideas? Is there any absolute method to try which will always cause the event to fire?

Month/Year Picker in a Grid FilterTemplate Issue

We are implementing a Month/Year picker (http://www.telerik.com/community/code-library/aspnet-ajax/calendar/month-year-picker.aspx#944510) in the FilterTemplate of a RadGrid. I have copied the code from the grid below. I have not been able to get the javascript to get a reference to the pickers ClientID - the compiler complains it does not know the TechManListPicker control.

Thanks
