Change page size for all detailgrids in hierarchical grid

I have a 2-level hierarchical grid. MasterTableView doesnt have paging. The detail grids do. If I change page size in one detail grid, I want that new page size to be applied to the rest of the detail grids. HierarchyLoadMode is "ServerBind" with DetailTableDataBind method. I tried to call MyGrid.Rebind() in PageSizeChanged event but DetailTableDataBind is only fired once for the grid that I switch the page size manually. How do I apply the new page size to all detail grids?

RadGrid OnSortCommand event triggered by Enter Key

Hi there,

The OnItemCommand, OnSortCommand got triggered unexpectly when pressing enter key in a textbox. Here is my scenario:

1 Click in a textbox below a RadGrid.

2 Press Enter key, OnItemCommand, OnSortCommand wil be triggered.

However, as soon as I remove the HeaderImageUrl property in telerik:GridTemplateColumn, everything works perfectly.

Please see the demo code below:

TestEnterKey.aspx:

Default a RadComboBox Filter

When I try to set a default filter on combobox filter the grid filters correctly but checkboxes in the filter do not display correctly. The filter says "All Items" instead of the two selected items.

01.protected void gridviewRequests_PreRender(object sender, EventArgs e)

02.{

03. gridviewRequests.MasterTableView.FilterExpression = "(ErrorStatus = 'Critical Errors' OR ErrorStatus ='Non-critical Errors')";

04.

05. GridFilteringItem filterItem = gridviewRequests.MasterTableView.GetItems(GridItemType.FilteringItem)[0] as GridFilteringItem;

06. RadComboBox combo = (RadComboBox)filterItem.FindControl("ErrorStatusFilter");

07. combo.Items.FindItemByValue("No Errors").Checked = false;

08.

09. gridviewRequests.MasterTableView.Rebind();

10.}

Rad Page Layout with SharePoint 2010/2013

Is RadPageLayout compatible with SharePoint 2010/2013 master-page and layouts?

I used below code in SharePoint project , it's working in desktop browsers but in mobile devices i got same desktop view not mobile view.

<telerik:RadPageLayout ID="RadPageLayout1" runat="server" HtmlTag="None" GridType="Fluid"

In times when the sales of tablets and smartphones exceed the sales of desktop PCs,

No surprise “responsive web design” has become such a buzzword—it’s what enables

Editform culture issue

Hi,

I'm currently working on a project where I need a radgrid with a couple of date columns. When the grid is in edit mode, the culture of the Datepickers however is always en-US. I need the culture to be nl-BE.

My columns are implemented as follows:

<Telerik:GridDateTimeColumn HeaderText="Start Date" UniqueName="StartDate" DataType="System.DateTime" DataFormatString="{0:dd/MM/yyyy}"></Telerik:GridDateTimeColumn>

I have tried setting the page culture, setting the culture of the grid in code and as suggested elsewhere on these forums the approach below

GridEditableItem item = e.Item as GridEditableItem;

RadDatePicker dpStartDate = item["StartDate"].Controls[0] as RadDatePicker;

dpStartDate.Culture = new CultureInfo("nl-BE");

All the datepickers on my form are correctly set to correct culture, except for the ones in the grid.

Am I doing something wrong?

RadContextMenu - iPad Safari (Right Click?)

So some of our end users have brought to light that they can't access our context menus via Safari on the iPad. I'm assuming this is an issue with no Right Click being available. I've attempted to figure out how to right click (double tap, two finger tap, long hold tap, etc.) but nothing seems to work... does anyone know how to perform a Right Click? If not, any ideas on how to resolve this? I guess we could simulate a long tap check with Mouse Down and Mouse Up...

IE gets unresponsive on image selection in RadEditor

Hi support,

We have upgraded our Telerik RadEditor to 2015.1.401.45 version.

We are facing issue in IE as mentioned below:
In IE when we select an image and change from Design to HTML mode or try to apply any paragraph style to it, the browser gets unresponsive.

I am able to reproduce the same behaviour with the Telerik demo: http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx?skin=Default

Can you please help us in solving this issue ?

Regards,
