Hi, I just started using the splitter control to create a admin page for my website. I have a left pane for my admin menu and a right pane for the content.

If I set the contentUrl to a page like google.com it works great. but if I use any page that has a logon screen when you logon it just flashes and re-loads the screen.

Anything I did internal to my site works fine but any external site with a logon doesn't. For yahoo mail the page loads fine but when I hit logon my entire page goes away and its just the yahoo logon page.

I know im trying to make this work like frames, but I want the user to be able to collapse the left menu if they need more room on the right pane.

Any Thoughts?
Thanks
-Keith

Performance SLOW

I am using a RadGrid with the following settings.

    
            <telerik:RadGrid ID="RadGrid1"   
        
            AllowMultiRowSelection="True"   
        
            AllowSorting="True"   
        
            AllowPaging="False"   
        
            AllowNaturalSort ="True"   
        
            AutoGenerateColumns="False"   
        
            AlternatingItemStyle-HorizontalAlign="Center"                                             
        
            BackColor="#ffffff"   
        
            HeaderStyle-HorizontalAlign="Center" 
        
            ItemStyle-HorizontalAlign="Center"   
        
            GridLines="None"   
        
            GroupingEnabled="True"   
        
            Height="370px"   
        
            OnSortCommand="RadGrid1_SortCommand"                                                       OnNeedDataSource="RadGrid1_NeedDataSource"                                                  OnItemDataBound="RadGrid1_ItemDataBound"   
        
            OnItemCommand="RadGrid1_ItemCommand"   
        
            ShowHeader="True"   
        
            ShowGroupPanel="True"   
        
            ShowStatusBar="True"   
        
            ShowFooter="False"   
        
            Skin="MySkin"    
        
            EnableEmbeddedSkins="False"   
        
            Width="98%"   
        
            runat="server">

It is calling a stored procedure that takes 4 seconds to run in PL/SQL developer. When I hook it up to the RadGrid it takes 40 seconds to load 10 X greater. When I use a regular GridView it takes 8 seconds. What is the RadGrid doing to slow the grid creation and how can I make it faster?

There are anywhere from 10-400 rows being returned.

Chart - ASP.NET AJAX Q2

Hello,

Im using radchart ajax Q2.

well,i have a problem i cant solve,actually its a bit difficult to explain so i will use a specific example.

my chart should display data about a single stock market - rate distribution.

the data can be calculate for different times durations:

1)Past Week (from today) -
   in this case i need to display on the XAxis 7 days = 7 points.
2)Past Month (from today) -
   in this case i need to display 4 weeks = 4 points.
3)Past 6 Months (from today) -
   in this case i need to display 6 months = 6 points.
4)Past Year (from today) -
   in this case i need to display 4 quarters = 4 points.
5)Past 2 Years (from today) -
   in this case i need to display 4 halfs = 4 points.
6)Betwwen 2 dates the user insert.

the user can choose the frequency to calculate the rates:

daily = i get an average rates for every single day between 2 dates(dynamicly).

weekly = i get an average rates for every single week between 2 dates(dynamicly).

monthly = i get an average rates for every single month between 2 dates(dynamicly).

yearly = i get an average rates for every single year between 2 dates(dynamicly).

OK,the problem begin here,for example :

the user can choose to display a chart for the past 6 months in 3 ways of frequency:
1)Daily -
   in this case my data source contains an average rate for each day = 180 points
2)Weekly - in this case my data source contains 4*6 = 24 points.
3)Monthly - in this case my data source contains 6 points for each month.

well,finally,my problom is that the Y values are not correlated to the X values,
i mean:

1)i have 180 Y values and 6 X values.

2)i have 24 Y values and 6 X values

3)i have 6 Y values and 6 X values.

how do i handle it ? is there any solution ?

Thank you in advanced,

yossi.

Strange behaviour when Rendering RadAjaxManager

Hi I am trying to add the RadAjaxManager programmatically to a page and override the Render method on the page. Here is my code:

    
            using System;  
        
            using System.Collections;  
        
            using System.Configuration;  
        
            using System.Data;  
        
            using System.Web;  
        
            using System.Web.Security;  
        
            using System.Web.UI;  
        
            using System.Web.UI.HtmlControls;  
        
            using System.Web.UI.WebControls;  
        
            using Telerik.Web.UI;  
        
            namespace Neetrix.Web.Administration.TempFiles  
        
            {  
        
                public partial class TestRender : Page  
        
                {  
        
                    protected void Page_Load(object sender, EventArgs e)  
        
                    {  
        
                        RadAjaxManager AjaxManager = new RadAjaxManager();  
        
                        AjaxManager.ID = "RadAjaxManager1";              
        
                        HtmlForm form = new HtmlForm();  
        
                        form.Controls.Add(new ScriptManager());  
        
                        form.Controls.Add(AjaxManager);  
        
                        form.Controls.Add(new LiteralControl("hello"));  
        
                        this.Page.Controls.Add(form);  
        
                    }  
        
                    protected override void Render(HtmlTextWriter writer)  
        
                    {  
        
                        writer.Write("<html>");  
        
                        base.Render(writer);   
        
                        writer.Write("</html>");  
        
                    }  
        
                }      
        
            }

After compiled and run it, it repeating itself when it reach the line "base.render(writer)". If you view page source on the page, you can clearly see that it duplicate both "<html>" and </html>" tags. If I took out the line "form.Controls.Add(AjaxManager)", it will behave correctly. So my question is, is it a bug or is there something i have missed? Thanks in advanced.

toolbar display error

my radeditor is not displaying properly. the icons in the toolbar are separated and disoriented. the clickable area is incorrect.. i.e. clicking on the icon sometimes doesn't trigger. I think this is a css problem, but I didn't even mess with the css properties yet..

the icons work properly in firefox but not ie 6 or 7...

[Solved] Calling a javasvript routine from ajax panel OnAjaxRequest server event

Hi

I am having trouble calling a javscript routine from inside the ajax panel server event.

i have an ajax panel which wraps severel controls on the page so that when the server events fire, they all fire through ajax and not postback.
One button in particular needs to do some database processing and then call a javsacript routine that will open a new window.

I have tried the following methods inside the button click routine.

string strBuildUp = "<script type=\"text/javascript\">";
strBuildUp += " PaymentGateway('" + OrderId.ToString() +"')</script>";
Page.ClientScript.RegisterStartupScript(this.GetType(), "paymentgateway", strBuildup);

I also tried
Page.Response.Write(strBuildUp);

and
Page.ClientScript.RegisterStartupScript(this.GetType(), "paymentgateway", " PaymentGateway('" + OrderId.ToString() + "')");

Then I tried to simplify the call with
Page.ClientScript.RegisterStartupScript(this.GetType(), "paymentgateway", "alert('hello'");
and
Page.Response.Write("alert('hello')");

if I remove the ajax panel then these will work fine!! (I like ajax I dont want to remove it)

None of the above worked for me I even replace registerstartupscript with register clientscriptblock (just in case).

I know that I can resolve this by creating an edit box on the page with no value, then creating a timer function that waits for a value to be added to the text box and then fires the javascript event from the javascript timer event.
On the server OnAjaxRequest event i simply put a value in the box and it all will happen.

But i was hoping for something a bit more tidier than that.
Does anyone know how i can achieve this without doing my suggested fudge?
