RadTreeList does not reflect updated data on UpdateCommand

I am using a RadTreeList with an UpdateCommand, which updates one BIT field on SQL Server via a stored procedure. After the update, I force the RadTreeList to rebind its data source, but it OCCASIONALLY will not reflect the updated data (which I know for certain is getting set on SQL Server). Sometimes it shows the new value, sometimes not.

What I have tried in the UpdateCommand:

protected void rtlRoster_UpdateCommand(object sender, TreeListCommandEventArgs e)
{

//some code eliminated for brevity

//Perform the update via SQL stored procedure
SQL.UpdateStoredProc(params...);

//I have tried sleeping before reloading the data source, which is not preferred
Thread.Sleep(1500);

     //I have tried forcing the data source to clear out explicitly and then resetting it to the proper data source afterwards
     rtlRoster.DataSource = new ArrayList();
     rtlRoster.DataBind();

//I have tried forcing it to reload the data source explicitly
rtlRoster_NeedDataSource(sender, new TreeListNeedDataSourceEventArgs(TreeListRebindReason.ExplicitRebind));

    //I have tried using this code from an online Telerik example (http://docs.telerik.com/devtools/aspnet-ajax/controls/treelist/data-editing/updating-records/using-inplace-and-editforms-modes)
     rtlRoster.EditIndexes.Clear();
     rtlRoster.Rebind();

//And I have tried the brute force way of reloading the page

Response.Redirect(Request.RawUrl);

}

I was hoping there would be some obvious setting that I could control, such as RadGrid's <ClientSettings><DataBinding EnableCache="false">, but I see no such property on the RadTreeList.

Any ideas why this would be happening intermittently and how to fix it?

ASP.NET version: 4.0.30319.34209 (though the .NET Framework is 4.5)
OS: Windows 8.1 Pro
exact browser version: IE11, Chrome 44.0.2403.155 m, and FF 39.0
exact version of the Telerik product: Telerik.Web.UI.dll 2013.2.717.45
preferred programming language (VB.NET or C#): C#

Thanks,

How to make dynamic update popup for dynamic grid in Kendo UI?

Here I have very nasty scenario. I have a grid that populate by using dynamic table.

In that grid i added the edit and delete functionality.

I also have validation requirement for all the columns in the grid.

here is a example...
Think the table have 2 columns(next time it can be 3 columns).

This table's data shows in grid. "ColumnA" (String) and "ColumnB" (float).

In a another table have validation rules for ColumnA and ColumnB.

ColumnA is a email and ColumnB have min and max values.

What I want is, make a custom dynamic popup for update data and bind these attributes to the html tags according to there validations.

How I achieve this ?? Thanks in advance.

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?

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.

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.

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...
