I have a RadCombobox and I use webservice datasource. Combobox could bind data and it show checkbox items.

When I click save button, I couldn't get combobox checkeditems collection. My code is here;

<telerik:RadComboBox ID="cmbNotificationUsers" runat="server" CheckBoxes="true" EnableCheckAllItemsCheckBox="true" Width="100%" OnClientItemsRequesting="OnClientItemsRequestingForUser"

EmptyMessage="Select" MarkFirstMatch="true" EnableLoadOnDemand="true">

<WebServiceSettings Path="../../WebServices/ControlObjects/ComboBoxes.asmx" Method="GetUsersByCompany" />

</telerik:RadComboBox>

foreach (Telerik.Web.UI.RadComboBoxItem item in cmbNotificationUsers.CheckedItems)

{

messageUsers.Add(item.Value);

}

Thanks,
Gökhan

MultiSelect filter for Dynamic Rad Grid

We are using Telerik Grid control in our application.
The Grid is getting constructed dynamically, i.e the columns to be shown in the grid is dynamic so we have created custom ItemTemplate and CustomFilterTemplate to implement this.
We have also implemented Column filtering in the Grid with combo box option.
Now, we need to make the filtering to have multiselect option. i.e. the Filter dropdown will show check box items so that user can choose multiple items to filter the Grid.
Could you please assist in this regard.
Attached file contains the screen shot of what we are trying to achieve.

Appreciate your assitance here.

Couple Things

I am trying to set the background color on the thumbnail area. Its BLACK, i tried css but it didn't work.

.RadImageGallery .rigThumbnailsList {

background-color: white;

}

I also get an error once lightbox is loaded from the thumbnail click event.

Say i have 6 images in the thumbnail and i click any thumbnail to open LightBox. It pops up with the correct image and showing say "Image 4 of 6" then i click one of the buttons to navigate and i get an ".../store/fake" - file does not exist. We dont have a fake directory, all files are loaded with advanced databinding. So confused why its looking for a file.

Also when i click again in the gallery after closing the lightbox, it seems its still loaded in memory. The image 4 is still showing from last click then it suddenly switches to say "2" which i just clicked to reopen the light box. Do i have to destroy lightbox after its closed?

Nested PageLayouts Padding Issue

It appears that nesting PageLayout controls (for example parent in Master page and child in Content page) causes the child control to be padded on all sides by roughly 20-30 px. What is the cause and a solution?

"Specified cas is not valid" Error when assigning Date variables to RangeSeriesItems

I have a RangeBarChart where the X Axis represents the time of the day from 6am to 10pm. The Y Axis represents a number of events. Each event consists of a StartTime variable and an EndTime variable (both are DateTime datatypes). I am adding the Series programmatically in ASP.NET VB.

The data is pulled from an SQL Database. When I assign the variables, I get a "Specified cast is not valid". Presumably, the RangeSeriesItem is looking for a different datatype than DateTime.

While UserReader.Read()

Dim AdjudicatorSeriesItem As New RangeSeriesItem(UserReader("fldNotesDateStart"), UserReader("fldNotesDateEnd"))

AdjudicatorSeries.SeriesItems.Add(AdjudicatorSeriesItem)

End While

Any ideas?

RadGrid Skin for controls in edit mode

I have a RadGrid which uses a SqlDataSource for adding, editing, deleting records.

When I click edit all the controls are standard asp.net controls (texboxes, checkboxes, etc) which means I cannot apply the Skin attribute.

How can I change those controls to telerik controls so I can style them like the rest of the grid view?
