Cannot Find RadGrid when in a RadPanelBar

I am having difficulty with the Persistence Framework. My application has a master page and the RadGrid is in a content page. When the RadGrid is at the root of the page (i.e. just under asp:Content), I can save/load the grid settings with no issue whatsoever. But that's not where I want my RadGrid. I want it in a RadPanelBar. And when I have it there, the Persistence Framework says it cannot find the control.

Here is some simplified code. This first part works:

<telerik:RadPersistenceManagerProxy
        ID="m_PersistenceManagerProxy"
        UniqueKey="ClaimswebFinancialsPayables"
        runat="server">
        <PersistenceSettings>
            <telerik:PersistenceSetting ControlID="m_rgPayables" />
        </PersistenceSettings>
    </telerik:RadPersistenceManagerProxy>

<telerik:RadGrid
ID="m_rgPayables"
runat="server"

... et cetera. But when I put the RadGrid in a RadPanelBar, the Persistence Manager says that it cannot find the control. Specifically if I put the RadGrid inside the ContentTemplate of a RadPanelItem.

Any ideas? I feel like I'm so close.

Problems after 2017 Upgrade

Hi,

I recently upgraded my application from the 2016 controls to the 2017 R2 controls and now I'm having issues with the Combobox and how it displays on the screen.

My combobox is within an Editform / form template of a RadGrid. It is defined this way:

<code>

<telerik:RadComboBox ID="rddRouteInner" runat="server" DataTextField="route" DataValueField="route"
DropDownHeight="200px" DropDownWidth="350px" AllowCustomText="true" Font-Size="12px" >
</telerik:RadComboBox>

</code

Very simple - no CSS applied or anything else. I added the Font-Size="12 px" because the font in the input was different from the drop down since the upgrade - which seems kind of crazy - but not a big deal.

Attached is what the output looks like. The Input Box is taller than the surrounding drop down box - and I get multiple drop down boxes (at least started). I have no idea how to troubleshoot this - when I just put a combobox on a page by itself - it works correctly.

Help?

Thanks!!!

ComboBox Custom Skin is not working after 2017 Update

We recently upgraded to 2017 Telerik for a project which had 2014 before.

ComboBox has custom skin, and it is not displaying correctly after update. After following a response on a different thread, i applied lightweight render mode for only combobox in config, which fixed the layover of image. But, it is not picking up the custom skin after that fix. Please advise.

Images attached here.

::before being inserted for an unknown reason

For an unknown reason ::before is being auto-inserted on some instances of RadRating but not others. How do I prevent ::before from being inserted when using RadRating?

Attached are screenshots of the user control code and the Chrome element inspector. In the code comparison attachment the code on the left auto-inserts "::before" and the code on the right does not.

RadTimePicker SelectedTime.Value Nullable Object must have Value

I'm reading in values from several TimePickers that may or may not be null. SelectedTime.Value throws the mentioned error when the value is a null and using DbSelectedDate with a (TimeSpan?) cast is invalid. Currently I'm accepting it as a (DateTime?) instead and breaking it down in an extra step. Is there a more elegant solution or is this the standard practice?

Dynamic Editable Grid - Object reference not set to an instance of an object

Hi,

I am creating columns programmatically based on the data return from database.

For example:

In Datatable i have following rows

ColumnHeader      EditorType
ABC                         TextBox
XYZ                          DropDown
AAA                          TextBox

My Grid display format should be

ABC XYZ AAA

Textbox Editor Dropdown Editor Textbox Editor

But i have an error in rgDynamic.Rebind()

Note:

DataBinding of dropdown editor done in ItemCreated event.

protected void rgDynamic_PreRender(object sender, EventArgs e)
{
   if (!rgDynamic.MasterTableView.IsItemInserted)
   {
       foreach (GridDataItem dataItem in rgDynamic.MasterTableView.Items)
       {
           if (dataItem is GridEditableItem)
           {
               dataItem.Edit = true;
           }
       }
   }
   if (rgDynamic.MasterTableView.Items.Count > 0)
       rgDynamic.Rebind();
}

RadGrid filter between dates (+ time)

Hi,

I'm trying to filter a grid between two dates.
It works but when the start- and enddate are the same (filter on one date) no results are shown.
The time is also included in the date so I'm guessing I need to adjust my code but I don't know how.

This is my current code:

    
            <telerik:RadScriptBlock ID="scriptFilterEventDate" runat="server"> 
        
                                                <script type="text/javascript"> 
        
                                                    function FromDateSelected(sender, args) { 
        
                                                        var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>"); 
        
                                                        var ToPicker = $find('<%# ((GridItem)Container).FindControl("dateTo").ClientID %>'); 
        
                                                        var fromDate = FormatSelectedDate(sender); 
        
                                                        var toDate = FormatSelectedDate(ToPicker); 
        
                                                        if (toDate != '') { 
        
                                                            tableView.filter("EventDate", fromDate + " " + toDate, "Between"); 
        
                                                        } 
        
                                                    } 
        
                                                    function ToDateSelected(sender, args) { 
        
                                                        var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>"); 
        
                                                        var FromPicker = $find('<%# ((GridItem)Container).FindControl("dateFrom").ClientID %>'); 
        
                                                        var fromDate = FormatSelectedDate(FromPicker); 
        
                                                        var toDate = FormatSelectedDate(sender); 
        
                                                        if (fromDate != '') { 
        
                                                            tableView.filter("EventDate", fromDate + " " + toDate, "Between"); 
        
                                                        } 
        
                                                    } 
        
                                                    function FormatSelectedDate(picker) { 
        
                                                        var date = picker.get_selectedDate(); 
        
                                                        var dateInput = picker.get_dateInput(); 
        
                                                        var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat()); 
        
                                                        return formattedDate; 
        
                                                    } 
        
                                                </script> 
        
                                            </telerik:RadScriptBlock> 
        
                                        </FilterTemplate>

    
            function FormatSelectedDate(picker) { 
        
                        var date = picker.get_selectedDate(); 
        
                        var dateInput = picker.get_dateInput(); 
        
                        var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, "dd/MM/yyyy HH:mm:ss"); 
        
                        return formattedDate; 
        
                    }

What should I change?
Thanks in advance!
