Questions on UI for ASP.NET AJAX Forum

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":
                    string removeFilter;
                    if (HttpContext.Current.Session["equalTo"] != null)
                    {
                        removeFilter = HttpContext.Current.Session["equalTo"].ToString();

                        if (grid.MasterTableView.FilterExpression.Contains("AND" + removeFilter))
                            grid.MasterTableView.FilterExpression =
                                grid.MasterTableView.FilterExpression.Replace("AND" + removeFilter, "");

                        if (grid.MasterTableView.FilterExpression.Contains(removeFilter))

I have a lot of records with 03/05/2012 as date

Steps 1:
filter as 03/05/2012 --> OK

Step 2:
Add Result equal to 4.

Does not work correctly.

in code behind Filter said:
[Date] = '03/05/2012 12:00:00 a.m. --> LOST the custom filter

Progress bar not moving on prod box IIS7. Works on Dev box

I am using the progress area to monitor a file generation. Not using the RadUpload with it. It appears on production, but doesn't move forward at all. Same in Chrome, IE, FF. This is on IIS, but the application is running at full trust and the page is NOT called Default.aspx. What could be the issue? I have a fiddlercap, but it doesn't let me post that file type here. What can I do? Thanks!

Issue in Date picker and time picker

8, IE 9 compatibility issue we are planning to upgrade into newer version (Telerik v2015.2.826.45).

We had a testing with trial version of Telerik v2015.2.826.45, we have faced the UI distortion issue in the RADDatePicker and RADTimePicker control. Below is the sample screen shot.

File Name in the attachment: ScreenShot1.png

We are using the custom css based on our site design, some cssclass is misplaced with the Telerik control along with our custom css classes. Below is the screen shot with one example compared with the older version and the newer version.

Batch Editing support for hierarchical grid

Hi,

We want to enable batch editing in three level hierarchical grid for only the last level child grid. First and second level grid will be readonly. Do Rad Grid support this functionality? if yes is there any sample code which implement this or implements the batch editing in hierarchical grid?

We tried setting Edit mode as batch for all grid but not able to get the client side changed values of last level grid at server side in Batch Edit Command event handler.

Awaiting your quick response, thanks for you help.
