[Solved] Unable to get property 'parentNode' of undefined or null reference

Hi,

I wasn't sure where to post this so I put it in General. I hope that that's ok! Anyway, I am facing the following issue. The line that is throwing the exception is bolded below. We are on version 2014.1.403.45 of Telerik. We are using a mix of Rad controls but I suspect that the issue relates to a RadComboBox.

Let me know if you require additional information and I will provide it no problem.

Thanks,
John.

disposeDomEvents:function(){var f=this.get_wrapper(),e=this._owner,d=e.get_inputDomElement(),c=e.get_imageDomElement();
$telerik.removeExternalHandler(f,"mouseover",this._onTableHoverDelegate);
$telerik.removeExternalHandler(f,"mouseout",this._onTableOutDelegate);
this._onTableHoverDelegate=null;
this._onTableOutDelegate=null;
if(d.parentNode){$telerik.removeExternalHandler(d.parentNode,"mouseup",this._onInputCellMouseUpDelegate);
this._onInputCellMouseUpDelegate=null;
}if(c){$telerik.removeHandler(c,"click",this._onImageClickDelegate);
this._onImageClickDelegate=null;
}}

Telerik with IE11 & VS2013 - not working

Hi,

Since installing IE11, running our app from VS2013 is problematic if there is a Telerik Grid control on an asp page. When I use VS2012 to run the app, all is fine. Here are the details of my setup:

* Windows 7 Enterprise, 64-bit, all updates installed
* IE 11, 64-bit
* Silverlight 5.1, 64-bit
* VS2012 Ultimate, SP3
* VS2013 Ultimate, SP1

See the attached screenshot.

Does anyone else experience a similar problem with the grid control?
Does anyone have a solution please?

Thanks in advance,
Christo

RadGrid: javascript set_dataSource not working

Hi

I followed the directions on the sample: http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/insert-update-delete-client/defaultcs.aspx, i am using a asmx web service to retrieve data like in the sample. Unfortunately i can not make the RagGrid shows the new data, the RadGrid only changes the width of the columns every time i press update button and keep the old data:

var tableView = $find("<%= rgCuentaGastosDetalle.ClientID %>").get_masterTableView();
            tableView.set_dataSource(result);
            tableView.dataBind();

            var grid = $find("<%= rgCuentaGastosDetalle.ClientID %>");
            grid.repaint();

I have reviewed the content of the result var and it contains the new data, and it does not send any error message. I have Telerik controls version 2014.1.403.40 and using framework v4.0.30319

Any question or comment please let me know. Thank you very much.

RadAjaxManager not updating all controls and not calling events (OnRequestStart/OnResponseEnd)

Hello

I am using the following code to perform Ajax on my ASP.NET Page:

<telerik:RadAjaxManager ID="ramDash" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1" >

<ClientEvents OnResponseEnd="responseEnd" OnRequestStart="responseStart"></ClientEvents>

<AjaxSettings

<telerik:AjaxSetting AjaxControlID="lvGrids">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="lvGrids" />

<telerik:AjaxUpdatedControl ControlID="lvListed" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"></telerik:RadAjaxLoadingPanel>

(...)

<div class="carousel">

<telerik:RadListView runat="server" ID="lvGrids" AllowPaging="true" OnItemDataBound="lvGrids_OnDataBound" DataKeyNames="GridID,Name,GridType" OnItemCommand="lvGrids_ItemCommand" OnNeedDataSource="lvGrids_NeedDataSouce">

<LayoutTemplate>

<ul>

<asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>

</ul>

</LayoutTemplate>

<ItemTemplate>

<li>

<!-- omitted for brevity -->

</li>

</ItemTemplate>

<SelectedItemTemplate>

<li>

</li>

</SelectedItemTemplate>

</telerik:RadListView>

</div>

(...)

<telerik:RadListView runat="server" ID="lvListed">

</telerik:RadListView>

Javascript:

function responseStart(sender, eventArgs) {

alert("test1");

}

function responseEnd(sender, eventArgs) {

alert("test2");

$(".carousel").jCarouselLite({

visible: 7,

scroll: 1,

circular: false,

btnNext: ".next",

btnPrev: ".prev"

});

}

I am using the "jCarouselLite" plugin to create a carousel effect and the "packery" JS component to create a sort of grid but they are not the problem. The problem is that the Ajax request/response is performed correctly as I can see using FireBug but the "responseStart" and "responseEnd" methods are not called and FireBug doesn't show any JS error.

I have tried putting the "ListView" (lvGrids) in an RadAjaxPanel and it works, because I can see the two alerts being: but the other ListView (lvListed) is not even updated (I can see the Ajax response and it doesn't include anything related to "lvListed". How can this be possible?

Thank you

Scroll Bars in Page View

So I think what I have is pretty straight forward. I have a tab strip with page views associated with each one. I have the scroll bars set to auto. They do not show up if the content stretches beyond the page. If I set the scroll bars to vertical they show but there is no way to scroll since the handle stretches the entire length of the bar. What do I have to do to make the scroll bars actually work?

<telerik:RadTabStrip SelectedIndex="0" ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1">

<Tabs>

<telerik:RadTab Text="Today" PageViewID="RadPageView1" runat="server" />

<telerik:RadTab Text="Personnel" PageViewID="RadPageView2" runat="server" />

<telerik:RadTab Text="Availability" PageViewID="RadPageView3" runat="server" />

<telerik:RadTab Text="Schedule" PageViewID="RadPageView4" runat="server" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" ScrollBars="Auto">

<telerik:RadPageView ID="RadPageView1" runat="server">

<uc1:TSTodayAlertControl ID="TSTodayAlert" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView2" runat="server">

<uc2:TSUserInfoControl ID="TSUserInfo" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView3" runat="server">

<uc3:TSAvailabilityControl ID="Availability" runat="server" />

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView4" runat="server">

Change RadPivotGrid header information when data binding information

I have a pivot grid to show some information, kind of a report, where the user can select a dates, From and To, and have to show a master header with the year, and right below the months, depending on what the user select. Now I have the years, and the months showing as I want except that I am showing the month number, not the month year (ex: 1 instead of January). I want to show January instead of 1. Here is the code and I attach some pictures.

<telerik:RadPivotGrid ID="RadPivotGrid1" runat="server" Skin="Glow" OnNeedDataSource="RadPivotGrid1_OnNeedDataSource"

AllowFiltering="False" RowTableLayout="Tabular" AggregatesPosition="Columns" ShowColumnHeaderZone="False"

ShowDataHeaderZone="False" ShowRowHeaderZone="False" AllowPaging="True" PageSize="50" ShowFilterHeaderZone="false"

AggregatesLevel="2" TotalsSettings-ColumnGrandTotalsPosition="None" TotalsSettings-RowGrandTotalsPosition="Last" >

<PagerStyle ChangePageSizeButtonToolTip="Change Page Size" PageSizeControlType="RadComboBox"></PagerStyle>

<Fields>

<telerik:PivotGridColumnField DataField="Year" UniqueName="Year" Caption="Year">

</telerik:PivotGridColumnField>

<telerik:PivotGridColumnField DataField="Month" UniqueName="Month" Caption="Month">

</telerik:PivotGridColumnField>

<telerik:PivotGridRowField DataField="DestinationName" UniqueName="DestinationName" Caption="Destination">

</telerik:PivotGridRowField>

<telerik:PivotGridAggregateField DataFormatString="{0:N0}" DataField="Teus" UniqueName="Teus" Caption="Teus">

<TotalFormat Axis="Rows" Level="0" SortOrder="Ascending" TotalFunction="NoCalculation" />

<HeaderCellTemplate>

<asp:Label ID="lblAggregateCellTEUS" Text="Calculated TEUS" runat="server" />

</HeaderCellTemplate>

</telerik:PivotGridAggregateField>

<telerik:PivotGridAggregateField DataFormatString="{0:C}" DataField="TotalCharge" UniqueName="TotalCharge" Caption="TotalCharge">

<TotalFormat Axis="Rows" Level="0" SortOrder="Ascending" TotalFunction="NoCalculation" />

<HeaderCellTemplate>

<asp:Label ID="lblAggregateCellTotalCharge" Text="Total Charges" runat="server" />

</HeaderCellTemplate>

</telerik:PivotGridAggregateField>

</Fields>

</telerik:RadPivotGrid>

Code behind:

private List<Result> LoadGridData()

{

var result = new List<Result>();

result.Add(new Result()

{

Year = 2014,

Month = 1,

DestinationName = "Miami, FL",

DestinationShortName = "MIA",

OriginName = "Miami, FL",

OriginShortName = "MIA",

TotalCharge = 100,

Teus = (decimal) 1.5

});

result.Add(new Result()

{

Year = 2013,

Month = 1,

DestinationName = "Miami, FL",

DestinationShortName = "MIA",

OriginName = "Miami, FL",

OriginShortName = "MIA",

TotalCharge = 100,

Teus = (decimal)1.5

});

result.Add(new Result()

{

Year = 2014,

Month = 2,

DestinationName = "Houston, Tx",

DestinationShortName = "Hou",

OriginName = "Miami, FL",

OriginShortName = "MIA",

TotalCharge = 80,

Teus = 2

});

result.Add(new Result()

{

Year = 2014,

Month = 1,

DestinationName = "Houston, Tx",

DestinationShortName = "Hou",

OriginName = "Miami, FL",

OriginShortName = "MIA",

TotalCharge = 80,

Teus = 2

});

return result;

}

protected void RadPivotGrid1_OnNeedDataSource(object sender, PivotGridNeedDataSourceEventArgs e)

{

RadPivotGrid1.DataSource = LoadGridData();

}

Any Help??

resizeToFit() in FireFox

Hi.

I am using this JS function on the client to resize the columns in a RadGrid located on a RadMultiPage. It works on FireFox as long as the Grid is "visible" i.e. in the active tab. If I do a post back from another Tab and then change back to the tab containing the Grid the MasterTableView has lost its width and the columns/headers are rendered inside the 0 px MasterTableView so they are not visible but they are there if i look at the html.

It works great on Chrome and IE but not on Firefox. Any ideas?

function ResizeGrid() {
    var grid = $find("<%= RadGrid1.ClientID %>");
    var masterTableView = grid.get_masterTableView();
    if (masterTableView) {
        var columns = masterTableView.get_columns();
        for (var i = 0; i < columns.length; i++) {
            columns[i].resizeToFit();
        }
    }
}

BR
Johan
