Handling context menu client side

in the OnClientItemClicked event the clickedMenuItem is null and the hidden form field which is set in the RowContextMenu is null? Am i using the right event?

in RowContextMenu "hiddenClientID" is correctly set to the ClientID key field

// process content menu

function RowContextMenu(sender, eventArgs) {

var colIndex = eventArgs.get_domEvent().target.cellIndex;

var rowIndex = eventArgs.get_itemIndexHierarchical();

var masterTable = sender.get_masterTableView();

cell = masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[rowIndex], "ClientID");

var ClientID = cell.innerHTML; //

document.getElementById("hiddenClientID").value = ClientID;

var radGridClickedRowIndex = document.getElementById("hiddenClientID").value;

var menu = $find("<%=RadContextMenu1.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

function contextMenuItemClicked(sender, args) {

var clickedMenuItem = args.get_item().get_value();

var radGridClickedRowIndex = document.getElementById("hiddenClientID").value;

var grid = $find('<%= RadGrid1.ClientID %>');

var masterTableView = grid.MasterTableView;

var row = masterTableView.get_dataItems()[radGridClickedRowIndex];

var cell = masterTableView.getCellByColumnUniqueName(row, "ClientID");

if (clickedMenuItem == "Edit") {

editClient();

}

if (clickedMenuItem == "Calendar") {

AddAppoint(cell.innerHTML);

}


<telerik:RadContextMenu ID="RadContextMenu1" runat="server" OnClientItemClicked="contextMenuItemClicked"             EnableRoundedCorners="true" EnableShadows="true" Skin="Metro">

Reference control in NestedViewTemplate

I have RadTreeView control inside a NestedViewTemplate of a RadGrid.

I want to reference this control in code behind so I can bind data to it, however I'm unsure of how to do this.

I was thinking it is something along this line:

Dim

RadTreeView1 As RadTreeView = CType(RadGrid2.MasterTableView.GetItems(GridItemType.NestedView.FindControl("RadTreeView1"), RadTreeView))

But this is incorrect. Can someone point me in the right direction

[Solved] Autogenerate numbers in RadGrid column based on group in GroupByExpressions RadGrid

I am having a trouble in implementing below requirement.
Current RadGrid: Attached (Snapshot 1) is the RadGrid in which I am using GroupByExpressions to display/show data grouped with "Business Unit" column.
In RadGrid column 2nd(InvoiceLineNo) and 3rd(InvoiceNo), I am auto generating the numbers using Stored Procedure.

i.e., for "InvoiceLineNo" column, Autogenerated No's are: 01,02,03,04,05,06,07,08.......n
for "InvoiceNo" column, Autogenerated No's are: 15100001, 15100002, 15100003........n
where, 15 is a "year" and 100001 are "running numbers"

Requirement is: I want to show the "InvoiceLineNo" column data as Group wise.
Example:
for 1st "Business Unit" group (i.e., SUNWAY LEISURE SDN BHD (CARNIVAL)), InvoiceLineNo shall be: 01,02,03,04,05,06,07,08
for 2nd "Business Unit" group (i.e., SUNWAY MALL PARKING SDN BHD), InvoiceLineNo shall be: 01,02,03,04,05,06,07,08

Similarly, I want to show the "InvoiceNo" column data as Group wise.
Example:
for 1st "Business Unit" group (i.e., SUNWAY LEISURE SDN BHD (CARNIVAL)), InvoiceNo shall be: 15100001,15100001,15100001,15100001,15100001,15100001,15100001,15100001
for 2nd "Business Unit" group (i.e., SUNWAY MALL PARKING SDN BHD), InvoiceNo shall be: 15100002,15100002,15100002,15100002,15100002,15100002,15100002,15100002

"InvoiceNo" column data will always be unique for different "Business Unit".

I want output to be like attached snapshot 2.

I can autogenerate the numbers serial wise but I am not getting how to autogenerate the 2 column values based on Group and show them like that.
Please help me to achieve it. Please do reply.
Thanks in advance.

Tristate image background-position incorrect after Telerik version upgrade

After upgrading Web dll's from version 2012.n to 2015.n the CSS property for the tristate.png is being set to incorrect values regardless of the .rtChecked, etc values are being set to (and have been set to). The values in the TreeView.css file are:

.RadTreeView .rtChecked { background-position: 0 0; }
.RadTreeView .rtUnchecked { background-position: 0 -13px; }
.RadTreeView .rtIndeterminate { background-position: 0 -26px; }

The values are being overridden from the now being set to:

.RadTreeView .rtChecked { background-position: 0 -40; }
.RadTreeView .rtUnchecked { background-position: 0 0; }
.RadTreeView .rtIndeterminate { background-position: 0 -80px; }

The dom explorer (in IE) is saying that this setting is held in the WebResource.axd file, which is a file dynamically created by the runtime.

Does anyone have any idea where these background-positions values are being set from so I can correct it, or help me understand what happened during the upgrade that caused these settings?

Thank you!

How to update all the successor tasks when updating the task

Hello,

I have a Gantt chart with tasks and dependencies.

Can anyone tell me how can I update "Start" and "End" of the tasks if it's parent task's "End" date is updated.

I tried doing the following code (@screenshot) in the TaskUpdate event, but it just refreshes the page, nothing else.

Any help will be appreciated. Thank you.

Ajax Control not whole grid

Hi Telerik,

We have a grid with an ItemTemplate code that contains a RadComboBox

<telerik:RadComboBox runat="server" ID="RadComboBoxEventNotAttending" Width="155px" CheckBoxes="true" DropDownAutoWidth="Enabled" AutoPostBack="true" EmptyMessage="Select Not Attending" EnableCheckAllItemsCheckBox="true"

OnItemChecked="RadComboBoxEventNotAttending_ItemChecked" OnCheckAllCheck="RadComboBoxEventNotAttending_CheckAllCheck" OnDataBinding="RadComboBoxEventNotAttending_DataBinding"

Label='<%# Eval("EventSubId")%>' LabelCssClass="myLabelHide" >

<Localization AllItemsCheckedString="Family not attending" CheckAllString="Select All" ItemsCheckedString="Member(s) not attending" />

<CollapseAnimation Type="InExpo" />

<ExpandAnimation Type="OutExpo" />

<HeaderTemplate>

<asp:Label runat="server" Font-Size="8" Text="Not Attending" />

</HeaderTemplate>

</telerik:RadComboBox>

Every Item for the grid could have different drop down items and checks for their respective repeating RadComboBoxes depending on the scenario, which is all handled fine with the OnDataBinding for each record in the grid datasource. When the user checks an item in the dropdown it does a whole postback for the grid. We would like it to only do a postback for the RadComboBox and show a LoadingPanel around the RadComboBox itself instead of showing around the grid.

Our grid is wrapped in a ASP Panel and is used in the RadAjaxManager. The RadComboBox could be wrapped in a ASP Panel and used the same way. We are not sure this is possible for it to be used inside a grid like this.

Could you supply some information or some code snippet for this type of situation?

Thanks!!!
