Do you have an example of how to pass in an argument (for example an image name) from a javascript function to a radlightbox when it opens?  I want to do something like the below, where the onmouseover in the <img src opens the lightbox if I hard code the value in the <asp:Image.
I need to load different images on different img src tags so I thought passing the image name via the funcion was the cleanest way to do so. 

Is this the best way to do this:

The disadvantage is that it looks like every image is loaded when the page is rendered, I was hoping it load the image dynamically.
Thanks for your help!



<script type="" >
function loadlb(imageName) {
        var rbx = $find('<%= rlbBox.ClientID %>');
        rbx.show();
}
</script>

<telerik:RadLightBox Modal="true" RenderMode="Auto" ClientIDMode="Static" ID="rlbBox" runat="server" ShowCloseButton="true">
        <ClientSettings><AnimationSettings></AnimationSettings></ClientSettings>
        <Items>
            <telerik:RadLightBoxItem>
                <ItemTemplate>
<asp:Image runat="server" ImageUrl="<image_from_loadlb>"/> 
                </ItemTemplate>
            </telerik:RadLightBoxItem>                 
        </Items>
</telerik:RadLightBox>


<img src=<some image> onmouseover="loadlb('imageToLoad'.jpg')" >

I have the following two RadListBoxes defined to allow switching items between them. All was well until I defined OnInserted and OnDelted, which fail to fire.

I  need to take action when anything is added to or removed from the right list box. This is they only way I'm aware of doing it, but like I said the events don't fire.

Here's the associated code:

 

 

Any help would be appreciated

Hi, 

I have Activity object which has childActivity which is a dynamic data type.

DataSource to grid is list of Activity.

How can assign few columns of grid with values of child object.

I was trying like below code.

 col.UniqueName = item.Name;

col.HeaderText = item.DisplayName;
(col as GridDateTimeColumn).DataField =  Activity.childActivity.Name;

 

Here is my code:

 

                   //var itemIndex = args.get_commandArgument();

I can't get the row index from get_itemIndexHierarchical() (JS error function does not exist). Also get_commandArgument() is blank if  I try that.

 

Can anyone help?

Hello!

i try to use the Colorpicker inside a FormView and want to bind property SelectedColor to SqlDataSource using the following code:

<telerik:RadColorPicker ID="colpickschedule_color" runat="server" Preset="Standard"
 ShowIcon="True" SelectedColor='<%# Bind("color") %>'>
</telerik:RadColorPicker>

when opening the form it says "specified cast is not valid".. this happanes when field in database contains some hex-color as string (#cacaca) and for DbNull-Values...

also tried something with ColorTranslator, but this only works for displaying data, null values throws some other errors..

can someone please explain how to do this? thank you!

What i want is to add a custom filter to one column that will takes the date from this column as first date and a date in another column as the second date to do a between like filter with these two dates.

I added a custom filter with  FilterListOptions="VaryByDataTypeAllowCustom".

then i added an handler like this (my second date is in "Col2") but this isn't working. What am i missing?:

Protected Sub gvAbsence_ItemCommand(source As Object, e As GridCommandEventArgs) Handles gvAbsence.ItemCommand
        If e.CommandName = RadGrid.FilterCommandName Then
            Dim filterPair As Pair = DirectCast(e.CommandArgument, Pair)
            If filterPair.First.ToString() = "Custom" Then
                Dim colName As String = filterPair.Second.ToString()
                If colName = "Col0" Then
                    Dim tbPattern As TextBox = TryCast(TryCast(e.Item, GridFilteringItem)(colName).Controls(0), TextBox)
                    Dim values As String() = tbPattern.Text.Split(" "c)
                    If values.Length = 1 Then
                        e.Canceled = True
                        Dim newFilter As String = "(([" + filterPair.Second + "] <='" + values(0) + "') AND ([" + "Col2" + "] >='" + values(0) + "'))"
                        If gvAbsence.MasterTableView.FilterExpression = "" Then
                            gvAbsence.MasterTableView.FilterExpression = newFilter
                        Else
                            gvAbsence.MasterTableView.FilterExpression = (Convert.ToString("((" + gvAbsence.MasterTableView.FilterExpression + ") AND (") & newFilter) + "))"
                        End If
                        gvAbsence.Rebind()
                    End If
                End If
            End If
        End If
    End Sub

Hi,

I'm attempting to print a RadGrid via JavaScript in Chrome.  I'm getting one of two results:

1. A blank preview window appears and prints a blank page.
2. An error stating "Print preview failed" appears.

Everything works as intended in IE 11. 

Here is my code.  Thanks!

I am having an issue with the data binding associated with expanding/collapsing items as well as with sorting.  For my RadTreeList data source, I am setting the data source to an ArrayList with information that is parsed from a web service. Whenever I expand/collapse an item or attempt to sort the items by a column, the data in the ArrayList is lost, and the RadTreeList refreshes to be empty.  Is there a way to save the data stored in the ArrayList between data bindings?  Extracting the data takes some time, so communicating with the web service each time is not very feasible.  Tell me if I need to provide any more detail.

Thanks!!
