Questions on UI for ASP.NET AJAX Forum

I am developing from the demo you provided here: http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/shareddatepicker/defaultcs.aspx?product=grid

In the OnItemCommand event handler I am looping through all the fields that have been changed and save or delete them when the "Update4 All" button is clicked. The problem is when the user clicks the "Add new Record" button. In the UI, the row appears and the user can add new values for each column. But when they click "Update All" this new row is not in the RadGrid1.Items collection. I would like to add this while I am updating and deleting the other rows. Is there a way to do this?

    
            protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e) 
        
            { 
        
                if (e.CommandName == "UpdateChanges") 
        
                { 
        
                    ArrayList editedItems = new ArrayList(); 
        
                    foreach (GridDataItem item in RadGrid1.Items) 
        
                    { 
        
                        if ((item is GridEditableItem) && (item.IsInEditMode)) 
        
                        { 
        
                            Hashtable ht = new Hashtable(); 
        
                            //add in delete flag 
        
                            ht["ShouldDelete"] = false; 
        
                            if (item.Selected) 
        
                            { 
        
                                ht["ShouldDelete"] = true; 
        
                            } 
        
                            //add in read only columns 
        
                            ht["ServerID"] = (item.EditManager.GetColumnEditor("ServerID") as GridTextBoxColumnEditor).TextBoxControl.Text; 
        
                            if (item.Selected || presenter.ValuesChanged((string)ht["ServerID"])) 
        
                            { 
        
                                item.ExtractValues(ht); 
        
                                //add in any template columns 
        
                                ht["OrderDate"] = ((TextBox)(item.EditManager.GetColumnEditor("OrderDate") as GridTemplateColumnEditor).ContainerControl.FindControl("TextBox1")).Text; 
        
                                editedItems.Add(ht); 
        
                            } 
        
                        } 
        
                    } 
        
                    if (editedItems.Count > 0) 
        
                    { 
        
                        presenter.UpdateAll(editedItems); 
        
                        XmlDataSource1.Save(); 
        
                        RadGrid1.Rebind(); 
        
                        notificationDisplayMsg.NotificationType = Trizetto.Web.UI.Controls.NotificationType.Information; 
        
                        notificationDisplayMsg.Text = "All changes have been saved."; 
        
                    } 
        
                } 
        
            }

Using RadMenu on MasterPage without Page Refresh

Hi,

I'm trying to design a master page with a RadMenu to navigate the user to the appropriate url without a full page refresh. All the pages share the same masterpage and need to find a way to have a loading panel display in the ContentPlaceHolder while only the ContentPlaceHolder refreshes.

Here is the code:

MASTER PAGE

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="DefaultTest.master.cs" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<

html>

<

head id="Head1" runat="server">

<title>Default</title>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

<link rel="Stylesheet" type="text/css" href="CSS/styleExternal.css" />

</

head>

<

body>

<form runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnableTheming="True">

</telerik:RadScriptManager>

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="ContentArea">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ContentArea" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadMenu ID="rmMain" runat="server" Skin="Default">

<Items>

<telerik:RadMenuItem runat="server" NavigateUrl="~/DefaultTest.aspx" TabIndex="1" Text="Dashboard">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" NavigateUrl="~/DefaultTest2.aspx" TabIndex="2" Text="School Information">

</telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

<

asp:ContentPlaceHolder ID="ContentArea" runat="server">

</asp:ContentPlaceHolder>

<

telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">

<table style="height: 100%; width: 100%" border="0">

<tr>

<td width="100%" align="center" valign="middle">

<asp:Image ID="Image1" runat="server" ImageUrl="~/Images/Loading/loading.gif"></asp:Image>

</td>

</tr>

</table>

</telerik:RadAjaxLoadingPanel>

</form>

</

body>

</

html>

Thanks so much for your help.

Is it possible to load usercontrol in RadMenu OnClientItemClicked?

    
            protected void RadMenu1_ItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)  
        
                {  
        
                    if (e.Item.AccessKey.ToString() == "1")  
        
                    {  
        
                        Control control = LoadControl("home.ascx");  
        
                        control.ID = control.ToString();  
        
                        ContentPlaceHolder1.Controls.Clear();  
        
                        ContentPlaceHolder1.Controls.Add(control);  
        
                    }  
        
                    else 
        
                    {  
        
                        Control control = LoadControl("abt.ascx");  
        
                        control.ID = control.ToString();  
        
                        ContentPlaceHolder1.Controls.Clear();  
        
                        ContentPlaceHolder1.Controls.Add(control);  
        
                    }  
        
                } 
        
The above code works fine. And the refresh is eliminated using RadAjaxManager, but for further development process we need do do the above function in client side. I dnt hve an idea whether its is possible, or is there any better method that can be followed to do this in client side. 

Thanks in Advance.

                grid.MasterTableView.ExportToExcel();
it exports the data in .xls format by default... i have excel 2007 installed in my machine
it also gives the warning messages as below

The file you are trying to open, <pagename>.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"

is there anything i can ovoid the format realted warning message? and also .xlsx file is very lighter than the .xls so we want to use the lighter version.

Thanks

Time picker in Advanced insert and edit form

Hi,

I started using telerik scheduler by downloading trial version - 2008.3.1314.35. In this we will have time picker which allows us to select time from a list - like 9:00 am, 8:30 pm so on. Then I used telerik licenced version - 2008.1.619.35. This has manually entering start time and end time column. Is there any way that I could get automatic time picker in this version?

Thanks

Filtering in a GridTemplateColumn with a LinkButton

My client wants to be able to click on a part number to begin editing the record. He also wants to be able to filter on the PartNumber field.

When I attempt to filter on the following column, I get the error "The query syntax is not valid., near keyword 'LIKE', line 6, column 6." (Using Entity Framework.

How do I get a LinkButton and filtering to work together?

Here's the code:

    
                                <telerik:GridTemplateColumn UniqueName="TemplateColumn4" AllowFiltering="True" Groupable="False" 
        
                                    HeaderStyle-Width="55px" ItemStyle-Width="55px" Reorderable="False" ShowSortIcon="True">  
        
                                    <ItemTemplate> 
        
                                        <asp:LinkButton  runat="server" CausesValidation="false" CommandName="Edit" 
        
                                            Text='<%#Eval("PartNumber") %>' /> 
        
                                    </ItemTemplate> 
        
                                    <HeaderStyle Width="55px"></HeaderStyle> 
        
                                    <ItemStyle Width="55px"></ItemStyle> 
        
                                </telerik:GridTemplateColumn>
