Multiselect RadCombobox with Filter issue

Hi,

I have a RadCombobox with Checkboxes and EnableLoadOnDemand features (Telerik Version 2015).

I am trying to use Filter for this RadCombobox but as soon as it filters the combobox values based on the search text, previous selection of the Combobox is not retained.

Please let us know if we can use Filter option of RadCombobox with checkboxes.

[Solved] Set Datepicker from SQL database

Hi, I am using RadDatePicker as follows:

<telerik:RadDatePicker ID="RadDATERECIEVED" runat="server" Culture="English (United States)" >
<DateInput runat="server" DateFormat="MM/dd/yyyy" MaxLength="10">

The picker works fine, you can pick the date, it formats with a maximum length.

I have two questions:

1. How do I set the DatePicker field so that the user cannot enter a date, it has to be chosen from the calendar.

2. I will be loading some records with an existing date from SQL that needs to be loaded into the DatePicker. What property do I use as I see no value property.

Thank you for your time. Dale,

RadGrid + Excel Filtering + AJAX = UpdatePanel Forever

Hi,

I'm using the new FilterType="HeaderContext" with my RadGrid. In this case I am going against a large set of items that may take some time to load when the user filters. So, I have the RadGrid set to register to itself with AJAX which seems to work well in all cases except when a filter is applied from the context menu. Here's what I observe:

1) User opens context menu and enters in filter criteria.

2) User clicks the 'Filter' button on the content menu.

3) The UpdatePanel displays as it should but, although I can see the filter properly applied to the grid in the background i.e. the items update properly, the UpdatePanel never closes. It just sits there forever. Note that other actions in the context menu (sorting for example) work properly and in those cases the UpdatePanel displays and then hides as expected.

I've got a minimal page that exhibits the behaviour (code below). What am I doing wrong? I really love the new excel filtering capability but I need to AJAX'ify it. Help!

Regards,

Greg

RadComboBox display issue

Hi,

I'm using a radcombobox to display a long list of projects for the user to pick from. When I view it in the Visual Studio development environment... or when I run it from visual studio, everything looks great. Unfortunately when it displays from the webserver - it loses the bottom border of the control. It is a minor thing but is annoying to my users.

My guess is that the CSS isn't correct on it but I have no idea where to start. I'm just using standard skins. I'll attach the two different views of the combobox.

Here is how it is defined in my code:

GridDatetimeColumn - Filter by Date Only - Error

I read a lot of this topic, but now I have an error when add other filter on grid.
this is my scenario

steps:
1- filter by date --> filter is OK.
2- filter by date, filter by colum x--> filter does not work because lost custom date filter.

This is my code:
public static void FilterDateTimes(RadGrid grid, GridCommandEventArgs e, string columnName, string actionFilter)
        {
            e.Canceled = true;
            var dateColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe(columnName);
            string newFilter;

            switch (actionFilter)
            {
                case "NoFilter":
