I am using tabstip in master page and chilf page holds contents.

Now, on change on Tabs i need to check whether i need to navigate or not, hence i am using OnTabSelecting and OnTabSelected event with "AutoPostback" = false and using __doPostback if i need to navigate.

Now ,sometimes if we click on tabstrip tab then tab opens but page is not posted back to the server through __doPostback is used.

Request you to please suggest.

"Date is out of range" alert for divehi(maldives) culture

Hi,
An alert with the message "Date is out of range" pop-ups when clicking on the "open the calendar" button.
I'm using the ASPNET AJAX Q3 2008, cannot change to the latest version nor the way of setting the culture.

You can reproduce it in this way:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="Test.WebForm3" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title></title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server"> 
        
                    </asp:ScriptManager> 
        
                    <telerik:RadDatePicker ID="RadDatePicker1" runat="server"> 
        
                    </telerik:RadDatePicker> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

    
            using System; 
        
            namespace Test 
        
            { 
        
                public partial class WebForm3 : System.Web.UI.Page 
        
                { 
        
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("dv-MV"); 
        
                    } 
        
                } 
        
            }

Thanks in advance

Access DetailTable Columns

I am using Rad Controls 2008 Q3 with Visual Studio 2008, C#, and .netFramework 3.5.

I have two issues:

I have a MasterTableView and two DetailTables. I need to programmaticially control the display of Edit and Delete columns based on a user's permissions. For example, I am using Grid.Columns.FindByUniqueName("MasterDelColumn") to locate the Delete column in the MasterTableView. However, when I try Grid.Columns.FindByUniqueName("DetailDelColumn") to locate the Delete column in the DetailTables, the program displays the following error: Cannot find column with UniqueName 'DetailDelColumn'. How do I locate the columns in the DetailTables programmatically?

I also need to display/hide the "Expand" icon, also based on a user's permissions. Is there any way to set the "Expand" icon Visible = false programmatically?

Thank you,
Jack

[Solved] Only first line is displayed in a multiline textbox

Hello,

I am trying to load data into a multiline textbox from a dataset. The RadTextBox shows only the first line of text. The same code using an ASP TextBos works fine. Any tips?

ASPX:
<telerik:RadTextBox ID="tb1" runat="server" Enabled="true" TextMode="MultiLine" Rows="4" Wrap="true" Width="100%" Columns="100"></telerik:RadTextBox>

<asp:TextBox ID="tb2" runat="server" Enabled="true" TextMode="MultiLine" Rows="4" Wrap="true" Width="100%" Columns="100"></asp:TextBox>

Code Behind:

tb1.Text =

"";

foreach (DataRow dr in ds.Tables[0].Rows)

{

if (tb1.Text == "")

tb1.Text = dr[

"Title"].ToString();

else

tb1.Text += Environment.NewLine + dr["Title"].ToString();

}

tb2.Text =

"";

foreach (DataRow dr in ds.Tables[0].Rows)

{

if (tb2.Text == "")

tb2.Text = dr[

"Title"].ToString();

else

tb2.Text +=

Environment.NewLine + dr["Title"].ToString();

}

Thanks!

Dropdown contents hidden

I recently installed RadEditor on a DNN site (2008.3 1314 on DNN 4.8.3). When I use the editor, the dropdowns (paragraph style, font name, real font size, etc.) are not displaying all of their content. In looking at the styles, the height of the dropdowns is set to 200px, but the dropdowns to not offer a scrollbar to access content below the 200px mark.

The following 2 styles are affecting this:

    
            .rade_dropDownBody {  /*WebResou...031489673 (line 267)*/ 
        
                overflow-x:hidden; 
        
                overflow-y:auto; 
        
            } 
        
            .rade_dropDownBody {  /*WebResou...031489673 (line 915)*/ 
        
                overflow:hidden !important; 
        
            }

If I disable the second style, the scrollbars appear as expected. Is there a setting or a fix for this that I am missing? Thanks.

[Solved] Check/uncheck bug in context menu

I'm trying to make it so that only one menu item can be checked at any one time. Sort of like radio buttons. But when I uncheck menu items programmatically the change doesn't show until I mouse over the items. Below is some sample code that demonstrates the bug. To recreate:

Click the button to open the menu
Check the first item, then check the second
Mouse over the first item to see check mark disappear

Find DetailTable Columns

I am using Rad Controls 2008 Q3, Visual Studio 2008, C#, and .netFramework 3.5.

I have two issues:

I have a MasterTableView and a DetailTables with two tables. I need to display or hide the Delete and Edit columns programmatically based on a user's security. For example, I have set the ID property for the telerik:radgrid control to G. I can control the columns in the MasterTableView with G.Columns.FindUniqueName("MasterEdit").Visible. However, when I try to access the DetailTables columns as G.Columns.FindUniqueName("Detail1Edit").Visible, I get the following error: Cannot find column with UniqueName 'Detail1Edit'. How do I access the columns in the DetailTables programmatically?

I also have the requirement to display or hide the "Expansion" icon that expands the grid to display the the DetailTables, also based on a user's security. Is there a way to programmatically display/hide this button?

Thank you,
Jack
