When the file size exceeds the Internet Explorer cannot display the webpage" error message

Hi,

I have come across a rare bug in the Rad Upload control. when the file size exceeds 5000 KB, not only the upload fails completely but it blocks the page from being posted back, and the "Internet Explorer cannot display the webpage" is shown instead.

I tried to hook the upload error event in "protected void RadUpload1_ValidatingFile(object sender, ValidateFileEventArgs e)"

But break point doesn't reach even there.

Please help me to find a solution for this.

Thanks in advance.

How to insert an image in the header and filter

Hi,

I need to display an image to the extreme right of the header and an image to the extreme right of the filter. This image will not be shown for each column but will be one image for the whole row and placed to the extreme right.
The columns are being dynamically created. The header, filter and item are all template columns.
Is there a way to insert an image into the header and the filter of the grid after the grid has been fully created?
Any help would be appreciated.
Thanks in advance.

RadGrid Resizable columns in a RadDock

Hi,

I have a pretty basic RadGrid sat within the RadDock. I have scrolling enabled on the RadGrid. If there are only a few record displayed in the RadGrid and I resize the columns the RadDock grows, which I don't want, it should remain fixed in size. However if there are a number of records present casuing the vertical scrolbar to appear and I resize the columns the RadDock stays fixed! Very quirky behaviour indeed!

All I want is for this the RadDock to remain fixed in size and the grid scrolls if the columns are resized!

Any help much appreciated!

[Solved] Vista skin horizontal divider display issue in IE6

We are using internal build 2008.2.905.35, which provided a fix for the Vista skin which was too blue in the release version of 2008.2.

In this build, in IE6 only, horizontal dividers in the menu (Vista skin) do not display properly. They render with a 1px width instead of extending the width of the menu.

It looks like this presently:

While it should look like this:

This is not a blocking issue, but I would hope you get it sorted out for your next release. If you do want to release another internal build with this fix, I'll open a support ticket. Thanks!

Highlighting the Selected Day

I am using a Date Picker to allow the user to change the selected date but the only highlighted day showing is the current day. Also when using the Navigation Commands to change periods the Selected Date changes but not the highlighting. Can this be handled through CSS? Code? If so, can you give me an example? Thanks!

How do i change the color of the scheduler?

Hi all,

I want to customize my scheduler, so that the empty time slot will be colored as well.

Currently I can only color the time slot that has been booked for an appointment.

through this code

    
            Protected Sub RadScheduler1_AppointmentCreated(ByVal sender As Object, ByVal e   As Telerik.Web.UI.AppointmentCreatedEventArgs) Handles   EquipmentScheduler.AppointmentCreated
        
                If e.Appointment.Attributes("ForceSaving") = "0"  Then 
        
                    e.Appointment.BackColor =   Drawing.Color.Red
        
                Else
        
                    e.Appointment.BackColor =   Drawing.Color.Orange
        
            Sub

but this code only applies for the time slot that already attached to an appointment, so does anybody know how do i change the time slot color for the time slot that is not attached to an appointment?

PROJECT DESCRIPTION

This project illustrates how to preform Grouping/UnGrouping action in RadGrid on double clicking the column header. The task is achieved by adding an OnColumnDblClick client event for the Grid and performing a PostBack from the client side. Then in the RaisePostBack event Grouping/UnGrouping can be performed.

RadAjaxManager1 grid postback

If I don't use RadAjaxManager1, the page postback and saves the scroll position just fine.

    <ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True">
        <Selecting AllowRowSelect="False"></Selecting>
        <Scrolling AllowScroll="True" UseStaticHeaders="False" SaveScrollPosition="true" ScrollHeight="300" />
    </ClientSettings>

If I use the RadAjaxManager1 as below - it scrolls to the top everytime i select a row on the grid via server side by clicking on the select GridButtonColumn. The scroll position is lost.

                <telerik:AjaxSetting AjaxControlID="rgMain">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="fvDetails"></telerik:AjaxUpdatedControl>
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="rgMain">

Can't send ImageUrl to radWindow

Hi, Im using 'Returning Values from a Dialog Demo' in my project, but i can't get asp:Image.ImageUrl and send it to radWindow. That work fine with textarea, but not with Images. I think that problem its in javascript. There are same way to send this value?

    
                        function showDialog() 
        
                        {                     
        
                            //Force reload in order to guarantee that the onload event handler of the dialog which configures it executes on every show. 
        
                            var oWnd = window.radopen(null, "DialogWindow"); 
        
                            oWnd.setUrl(oWnd.get_navigateUrl()); 
        
                        } 
        
                        //Called when a window is being shown. Good for setting an argument to the window  
        
                        function OnClientshow(radWindow) 
        
                        {                     
        
                            //Get current content of textarea 
        
                            var oText = document.getElementById("ImageFoto1"); 
        
                            //Create a new Object to be used as an argument to the radWindow 
        
                            var arg = new Object();                     
        
                            //Using an Object as a argument is convenient as it allows setting many properties. 
        
                            arg.ImageUrl = oText.ImageUrl;  // This don't work 
        
                            //Set the argument object to the radWindow         
        
                            //radWindow.Argument = arg; 
        
                            radWindow.Argument = arg; 
        
                        }

Thanks for your support.

	function showDialog()
	{
	//Force reload in order to guarantee that the onload event handler of the dialog which configures it executes on every show.
	var oWnd = window.radopen(null, "DialogWindow");
	oWnd.setUrl(oWnd.get_navigateUrl());
	}

	//Called when a window is being shown. Good for setting an argument to the window
	function OnClientshow(radWindow)
	{
	//Get current content of textarea
	var oText = document.getElementById("ImageFoto1");

	//Create a new Object to be used as an argument to the radWindow
	var arg = new Object();
	//Using an Object as a argument is convenient as it allows setting many properties.
	arg.ImageUrl = oText.ImageUrl; // This don't work


	//Set the argument object to the radWindow
	//radWindow.Argument = arg;
	radWindow.Argument = arg;
	}
