I am using RadGrid of AJAX, the grid is in a user control which is add DYNAMICALLY when a button is click, my issue here is that after the user control is loaded, i can do filtering in the grid the first time, but if i filter again, I got JS error :Unable to get value of the property '_showFilterMenu': object is null or undefined. I place RadAJAXManager only in the user control, and in parent page, there is only RadScriptManager. Why does this happen? This works if I add user controls at design time, but in my case, there are several grids i need to load base on different button click and each grid contains hundreds of rows, so concerning about performance, I have to add them dynamically. Please help me out.

Thank you!

 

I need help for the following scenario.

1. In inline edit mode if I double click  a row It has to changed to edit mode.
2. Once again if I doucle click the edited row Or if I select the another row for edit,  it should call the Update and the changes made in the row to be reflected in the datatable.

  Hello, I have enabled grouping on my programatically (dynamic) created RadGrid.  I am persisting the group expressions through cookies and all it working well.  By default, all the groups are expanded.  When I collapse a set of rows they collapse just fine.  However, when I try to expand those same rows nothing happens.  The page appears to be doing a post-back, but not change is made on the screen.  No error, no message at all. 
  I'm guessing that the code is executing a toggle operation and believes (due to it's dynamic nature) that I clicked on an expanded node that needs to be collapsed.  And thus it is doing exactly what it is supposed to.  Is there a way to have the expand/collapse done on the client side so that a post-back does not have to occur?  Or does the fact that the item collapsed needs to be persisted in some manner.  Any direction in either path would be appreciated.

Hello,

We have a slider bound to the RadSlider similar to the demo on http://demos.telerik.com/aspnet-ajax/slider/examples/rangeslider/defaultcs.aspx. sorry project is  on or dev platform which is not accessible.

the difference is at each step in the slider we are passing in content to populate the tool tip that will lead the user to a different page. The issue we have is if the user clicks on ether the rsTrack or the increase/descrease handles, the tool tip appears in different heights at different steps.

How can we keep it so the tool tip is always bound to the rshandle.

here is the code we are using

<telerik:RadToolTip EnableShadow="false" BorderStyle="Solid" BorderWidth="10" OffsetY="5"
            HideDelay="1" ID="RadToolTip1" runat="server" RelativeTo="Element" Position="TopCenter"
            ShowCallout="true" Width="425px" ShowEvent="fromcode" HideEvent="FromCode"
            EnableEmbeddedSkins="false" Skin="SLIDER">
        </telerik:RadToolTip>
        <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

            <script type="text/javascript">
                function OnClientLoad() {
                    ShowRadToolTip(tooltip, sender);
                }
                function OnClientValueChange(sender, args) {
                    if (!isSliding) return;
                    var tooltip = $find("<%= RadToolTip1.ClientID %>");
                    ResetToolTipLocation(tooltip);
                    tooltip.set_text(GetItemValue());
                }

                function OnClientValueChanged(sender, args) {
                    var tooltip = $find("<%= RadToolTip1.ClientID %>");
                    ShowRadToolTip(tooltip, sender);
                    tooltip.set_text(GetItemValue());
                }

                var isSliding = false;
                function OnClientSlideStart(sender, args) {
                    isSliding = true;

                    var tooltip = $find("<%= RadToolTip1.ClientID %>");
                    ShowRadToolTip(tooltip, sender);
                }

                function OnClientSlideEnd(sender, args) {
                    isSliding = false;
                    var tooltip = $find("<%= RadToolTip1.ClientID %>");
                    ShowRadToolTip(tooltip, sender);
                }

                function ShowRadToolTip(tooltip, slider) {
                    var activeHandle = slider.get_activeHandle();
                    if (!activeHandle) return;
                    tooltip.set_targetControl(activeHandle);
                    ResetToolTipLocation(tooltip);
                }

                function ResetToolTipLocation(tooltip) {
                    if (!tooltip.isVisible())
                        tooltip.show();
                    else
                        tooltip.updateLocation();
                }
                function GetItemValue() {
                    return $find('<%= InvestmentsSlider.ClientID %>').get_items()[$find('<%= InvestmentsSlider.ClientID %>').get_value()].get_value();
                }
            </script>
        </telerik:RadCodeBlock>
        <telerik:RadSlider runat="server" ID="InvestmentsSlider" Height="200px"
            style="margin: auto;" IsSelectionRangeEnabled="false" OnClientSlide="OnClientValueChange" OnClientLoad="OnClientValueChanged"
            OnClientValueChanged="OnClientValueChanged" OnClientSlideStart="OnClientSlideStart"
            OnClientSlideEnd="OnClientSlideEnd" ShowDecreaseHandle="true" ShowIncreaseHandle="true"
            ItemType="Item" />

Forget it. The template I was working from was done by another programmer who I don't have contact with ... or trust.

Hello,

the difference is at each step in the slider we are passing in content to populate the tool tip that will lead the user to a different page. The issue we have is we need to the tool tip to appear on page load and be bound to the rsHandle. All effeorts have made the tool tip appear but it shows cenetered on the page rather than above the slider handle.

We are setting the ExportSettings.Rtf.PageHeader property and exporting to rtf using ExportToRtf(). Is it possible to print the rtf version from the editor?

Hi Telerik,

I have a RadSlidingZone which has ClickToOpen enabled. I would like to cancel the opening event (or not fire it) when the user right-clicks. It's weird to have a context menu open with the sliding zone opening up, too.

How can I achieve this? Is it implicitly supported, or do I need to capture the click event and figure out if its a right click in JS?

What is the recommended technique to filter out HTML paste when it contains <form> tag?    It's conflicting with the way submit is working.   The editor supports HTML paste.

I have a self-referencing hierarchical grid set up. I need to have insert functionality available for any hierarchical level. When a row is expanded to show the children records I need to hide the non selected parent records and disable the selected parent. This is working correctly. The issue I need guideance on is that I also need to suppress the option to insert a row into the parent's hierarchical level if a child is open. Otherwise, at each level of hierarchy there is an option to insert a record which is confusing to the users since we are hiding the rows for that hierarchical level. I'm sure looking at the code could make this a little more clear . . .

This is a simple self-refrencing hierarchical grid with automatic inserts enabled:

Here is the ItemCommand which is suppressing the non selected hierarchical rows. There is a block of noted out code in the middle of this which shows a couple of things I have tried without success.


Please let me know if there is a way to do this. My next step was going to be to throw out the self-referencing and add detail tables for each level of hierarchy, but that seems down right silly.

Thanks,
Casey
