Masterpage has a header, sidebar for navigation and the remainder contains a div that hosts the contentplaceholder. Usercontrols are loaded into the contentplaceholder when the user selects items in a list displayed on the left sidebar area.

    
                <div id="content" class="content" runat="server" > 
        
                    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">  
        
                    </asp:ContentPlaceHolder> 
        
                </div><!-- end content -->

The style for this div is as follows:

    
            .content {  
        
                display:block;  
        
                font-family: Arial, Helvetica, sans-serif;  
        
                font-size: small;  
        
                background-color: #FFFFFF;  
        
                left: 218px;  
        
                top: 85px;  
        
                text-align: justify;  
        
                position: fixed;  
        
                margin: 85px,218px,0,0;  
        
                overflow: auto;  
        
                height: 100%;  
        
            }

The style for the header:

    
            .header {  
        
                display:block;  
        
                top:0px;  
        
                left:0;  
        
                position:fixed;  
        
                text-align:left;  
        
                background:#00453D url(logo.gif) no-repeat fixed 0px 5px;  
        
                height: 85px;  
        
                vertical-align: bottom;  
        
                padding: 0px;  
        
                visibility: visible;  
        
                border-bottom: 10px solid #FDDEA9;  
        
                z-index: 1;  
        
                width: 100%;  
        
            }

Everything works EXCEPT - the scrollbar for the div/contentplaceholder does not appear for the first 85px (the height of the header).
If I remove the .top value for .contentplaceholder, the scrollbar appears correctly, but of course the first 85px of the usercontrol loaded within the Contentplaceholder is clipped.

I've tried numerous different CSS settings w/out success (and a few of the above do not seem to have an impact).
If anyone has suggestions or even links to articles on CSS usage that might cover this, it would be appreciated.

[Solved] Object reference not set to an instance of an object. findcontrol

RadDateInput maxDate

Hi all,

Can anyone tell me why the following javascript is not working?

document.body.onload = function() {

var txtDOB = document.getElementById("<%= txtDOB.ClientID %>");

txtDOB.set_maxDate(new Date('2009/04/15'));

}

The error I get is "Object doesn't support the property or method" on the set_maxDate line.

My aspx markup is

<telerik:RadDateInput ID="txtDOB" runat="server" DateFormat="dd/MM/yyyy">

</telerik:RadDateInput>

I am using Telerik Q2 2009 (2009.2.826.35)

Thanks

Radlistbox - datatextfield

Hi,

I've a radlistbox and I set the datasource:

List<CMListItem> obCMListItem = new List<CMListItem>(); (where CMListItem is a class).

m_radListBox.DataSource = obCMListItem.

This obCMlistItem has ItemName,Itemdescription and Item code as 3 elements.

I need to set my datatextfield of the radlistbox by combining the 2 elements of the class( combining ItemName and Itemdescription).

If I try to do the below approach, I get an error:

            m_radInstitutionLstBox.DataTextField = String.Format("{0},{1}", Properties.Resources.Ttl_Col_ItemName , Properties.Resources.Ttl_Col_ItemDescription);
            m_radInstitutionLstBox.DataValueField = Properties.Resources.Ttl_Col_ItemName;
            m_radInstitutionLstBox.DataSource     = obCMListItem;
            m_radInstitutionLstBox.DataBind();

How can i handle this situation. Pls help me with code in c#

Thanks,
ZR

Problems with custom FileBrowserContentProvider for RadEditor

Hello

I'm trying to implement custom content provider for ImageManager used in RadEditor. I'm facing with some problems and also I've got some questions about its functionality. I'm using 2009 Q3 version of Telerik Controls.

Problem:

1) When I try to perform upload operation I always get an error message (displayed as a javascript-driven window) which says:
%filename% - Cannot write to the target folder! , where %filename% is a name of file which I try to upload. I have tried to debug it and found out that server method FileBrowserContentProvider.StoreFile does not get executed at all, e.g. breakpoint which I place at the beginning of it doesn't get hit.
I have already saw similar message here, but it was posted a while ago and somebody of Telerik support team answered that it was a bug of 2009 Q1 version and it would be fixed in further release.

Questions:
In general, I'm curious about how I may customize the appearance of ImageManager dialog:
1) Can I remove size column of folder browser?
2) Can I specify somehow which folders user is allowed to upload files into and which ones are read-only? For example, I want to disable uploading files into root folder, but to allow doing this with all subfolders of root one.
3) Can I disable renaming folders?
4) Can I disable deleting folders?

Disabling doing something also means for me hiding button or other control, which is used for doing this (delete button, upload button and so on)

Thanks in advance,
Vladimir.

The telerik library version i'm using is 2009.2.701.35. Maybe they are in the Q2 sp1? Can someone answer? Thanks.
