I am creating a batch grid.  One of the cells in this grid is telerik:GridTemplateColumn ("Value" in the code below)  The EtidItemTemplate contains different objects.  Depending on the selected field type, only one of the objects is displayed.  So, if the field type is date, a calendar will be displayed and the other types - hidden.

Here are the issues I am coming across at the moment:
1. if the field type is text, the first time the user enters text into the box and moves out, the selected value is displayed as blank.  If I re-open the text box and enter the value once more, it shows up.
2. If field type is telerik:RadComboBox, I would like the ItemTemplate to display a comma delimited list of descriptions but the best I can do is a comma delimited list of IDs.  I need to be able to save the selection as list of IDs but display a list of descriptions to the user.
3. if I am editing an item that was saved earlier, the change is not processed.  I only see delete and insert being processed.

Here is the code for the aspx and code behind.
Thank you!

Hi I'm new here and I'm currently working with ASP.NET WebForms.

I had some issues trying to bind sources to a RadMediaPlayer that's inside a ASP Repeater:



The repeater source is provided by a stored procedure which is called in code-behind and then I use the "OnItemDataBound" event of the repeater to format each ItemTemplate. I'm doing all this steps because I'm working on a social network and I want to manage different posts (images,videos,songs,etc).

Here is the code-behind of the repeater event:  


The data bind of the repeater is working fine, for example the images binding is perfect but not the audio binding. You can see the player there but when you press play nothing happens, it seems like the source isn't there but i checked with the javascript console of google chrome and the source is there.

Here is also the static class that provides the path to the project local folder where the files (images,songs,videos,etc) are stored:


I hope you can help me.

Thanks in advance.

John.

Hi All,
I have a RadDatePicker control and I need to validate the date. The user must enter a valid date and I have to check the date is not greater that the DataTime.Now value.
I am trying to build a method to handle both cases and send the corresponding error message. It looks I do not have the choice to call a method from the RequiredFieldValidator control.
Do you have any suggestion to handle this case?
Thanks
Yuri.

I've got an expandable grid that I'd like to fill the child as a Floated Tiles ListView.  Each of the cells (or tiles) in the listview have set widths and are rows/records from a datasource.  Depending on the right margin it would be good if the cells could wrap, but if not a set number of columns would be fine.  Whats the best way to achieve this?  

+ Row 1
   [1][2][3][4][5][6]
   [7][8][9][10][11]
   [12][13][14][15]
   [16][17][18][19]
- Row 2
- Row 3

Reducing the width would wrap the cells
+ Row 1
   [1][2][3][4]
   [5][6][7][8]
   [9][10][11]
   [12][13]
   [14][15]
   [16][17]
   [18][19]
- Row 2
- Row 3

cheers

I'd like to add separators in the editor context menu - is this supported? The Tools section uses <telerik:EditorSeparator /> but this is not recognized inside the <ContextMenus> section.

No matter what I do, the dropdown arrow for the combo box only shows up on mouse over.  I have removed ALL css from the page to eliminate that as an issue and it still happens.  I've tried using a RadFormDecorator and selecting a different style theme as well but the same display issue persists.



See attached images.

Anyone have an idea?

We use your RadWindow controls quite a bit in our application. They are invoked using the following JavaScript convention…

 

var oWnd = radopen("EditWBSEast.aspx", "WBSRadWindow");

oWnd.setSize(830,300);

oWnd.Center();

 

We define WBSRadWindow as follows:

 

<telerik:RadWindowManager

    ID="RadWindowManager1"

    runat="server"

    Behavior="None"

    InitialBehavior="None" Left=""

    Skin="Outlook"

    style="display: inline;"

    Top=""

    DestroyOnClose="True">

    <Windows>

        <telerik:RadWindow

            ID="WBSRadWindow"

            Modal="true"

            runat="server"

            Behavior="None"

            DestroyOnClose="True"

            InitialBehavior="None"

            Title="”

            ReloadOnShow="true"

            Left=""

            NavigateUrl=""

            style="display: inline"

            Top=""

            Behaviors="None"  

            OnClientShow="OnClientShow">

        </telerik:RadWindow>

    </Windows>

</telerik:RadWindowManager>

 

This code provides us with a rather generic window with very little functionality but vastly better looking than the corresponding Window(Open) or Javascript alert. Our one problem is that we would also like to suppress the horizontal and vertical scrollbars.

 

We have seen elsewhere in your documentation that a JavaScript method similar to the one below should accomplish this…

 

    function OnClientShow(radWindow)  

    {   

 

       var delScrollbar = radWindow._name;

       document.getElementsByName(delScrollbar)[0].setAttribute("scrolling", "no");

 

 

       var oTop = document.documentElement.scrollTop;  

       document.documentElement.scroll = "no";  

       document.documentElement.style.overflow = "hidden";  

       document.documentElement.scrollTop = oTop;  

 

       if(document.documentElement && document.documentElement.scrollTop)  

       {  

           var oTop = document.documentElement.scrollTop;  

           document.documentElement.scroll = "no";  

           document.documentElement.style.overflow = "hidden";  

           document.documentElement.scrollTop = oTop;  

                

       }

       else if(document.body)  

       {  

            var oTop = document.body.scrollTop;  

            document.body.scroll = "no";  

            document.body.style.overflow = "hidden";  

            document.body.scrollTop = oTop;  

        }  

    }  

  

This method does not suppress the scrollbars for us. Could you advise us as to how to best accomplish this?

 

 

Thanks

 

 

 

 

 

I've been fighting with this issue for hours and hours now and I'm about ready to throw Rad controls out the window, it's so counter-intuitive.

I have a Radgrid called MyGroupsRadGrid01.  This grid displays a list of groups I'm in.  When I click on the Edit command of one of the rows, it displays the details of the group as well as a RadGrid of the other members in the group called GroupMembersRadGrid all within a FormTemplate.  I want to be able to add or delete an entry in GroupMembersRadGrid using GroupMemberRadGrid_DeleteCommand() and GroupMemberRadGrid_InsertCommand().  I tried using GroupMemberRadGrid_NeedDataSource() but the method itself cannot find GroupMemberRadGrid.  I then tried populating GroupMemberRadGrid within MyGroupsRadGrid01_ItemDataBound but after deleting an entry, the GroupMemberRadGrid showed up as empty (which seems to me necessitate's the GroupMemberRadGrid_NeedDataSource() that I can't get to work.  




It's 9:00pm and I've been working on this since noon.  I can't fight with this all night and it's due in 11 hours.  I need help.

Data in the file exported to excel is incorrect plz help me

After hours of research, I have figured out my own solution to some issues I reported earlier. So to summarize all my issues and solutions:

I experienced two major BINDING issues with fields under <EditFormSettings EditFormType="Template"><FormTemplate>:

1. DropDownList - Setting the SelectedValue property to <%# Bind("security_webpage_id") %> caused an error when clicking on the Add New Record button. The error was 'ddlWebPages' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value.

Fix: I added a blank listitem. My Dropdown tag looked like this after fix:

<asp:DropDownList ID="ddlWebPages" DataSourceID='sqlDataSourceWebpages'
                                               AppendDataBoundItems="True" DataTextField="webpage_name" DataValueField="ID"
                                               SelectedValue='<%# Bind("security_webpage_id") %>' runat="server"> 
                                      <asp:ListItem Text=" " Value=""></asp:ListItem>
                                          
</asp:DropDownList>
 
2. Checkbox - I had three checkboxes that received an error when I clicked on the Add New Record button.
The error was "Specified cast is not valid".

Fix: I created a User Control for the CheckBox and handled the passing of null value to the Checked property which is what was happening when the Add New Record button was clicked. Below is my code for the code behind and markup of the checkbox control.

Code-Behind:



Mark-up:


Registering User Control in markup file that contains the standard Checkbox;

Your Checkbox and/or Drop Down List will look like this now under the FormTemplate:

Hopefully this will help someone else not have to go through days of pain that I did over there two issues
