HeaderContextMenu and Custom Grid Context Menu

I've got a custom Context Menu that is accessible from anywhere in my grids for setting gridlines (horizontal, vertical, both, none), or export to excel, which I've gotten to work very well.

I would also like to include the HeaderContextMenu (columns) only, so the users can customize the columns displayed. I've been completely unsuccessful in getting those to work as one item. In short, is there an easy way to add the columns like those shown in the HeaderContextMenu to my custom context menu and have it function like it does from the HeaderContext menu, with persisting the displayed columns after the users makes their column display choices.

As it is now, I have my custom context on the grid and the headercontext columns accessible from the header only.

[Solved] Javascript equivalent of onchange()

I would like to fire a RadComboBox's SelectedIndexChanged event from another function in JS. For a standard dropdown list I would use "onchange()" but for the RadComboBox I get TypeError: RadComboBox1.onclick is not a function. Is there a way to fire a selectedindexchanged event from javascript on a radcombobox?

Example:

function fireSelectedIndexChanged() {

var comboBox = $find("<%=RadComboBox1.ClientID%>");

comboBox.onchange(); <---- fire selectedindexchanged event

}

Kendo MVC (razor) Grid (with Batch Edit) - Lines disappear on Cancel

When my MVC razor Kendo Grid is in:

GridEditMode.InCell

and I click on "cancel changes"
or in:

GridEditMode.InLine

and click on "cancel" Changes,

The lines are dropped from the grid..

Apparently this has to do with the fact that I load my grid on the client ajax call (generated by a treeview). It seems as if the grid is treating the lines as new because they were loaded at a later time then when the grid was created.

What can I do to avoid this problematic behaivior? I have read many users have similar issues but no straightforward solution.

Here is my JavaScript:

01.function onSelect(e) {

02. var node = e.node;

03. var nodedata = $("#tvPH").data('kendoTreeView').dataItem(node);

04. //Fill the Proc Equip Grid

05. if (nodedata.nodeType == "pls") {

06. $.ajax({

07. //url: "/PlantHierArchy/GetProcEquip?plsID=" + nodedata.id,

08. url: "/PlantHierArchy/ForeignKeyColumn_Read?plsID=" + nodedata.id,

09. dataType: "json",

10. cache: false,

11. type: 'GET',

12. success:

13. function (result) {

14. $("#lblPSU").text('Proc. Equipment Managment for Plant Sub-Unit: ' + node.textContent);

15. var procGrid = $("#ProcEqGrid").data("kendoGrid");

16. procGrid.dataSource.data(result.Data);

17.

18. },

19. error: function (jqXHR, textStatus) {

20. alert("Request failed: " + textStatus);

21. }

22. });

23. }

24. }

and here is my Grid:

01.@(Html.Kendo().Grid<PMTWebReconcile.Models.ProcEquipViewModel>()

02. .Name("ProcEqGrid")

03. //.HtmlAttributes(new { style = "height: 480px; margin-left: 260px" })

04. .Columns(columns =>

05. {

06. columns.Bound(P => P.peqID).Width(20);

07. columns.Bound(P => P.peqName).Width(120);

08. columns.Bound(P => P.peqTag).Width(120);

09. columns.Bound(P => P.peqDescription).Width(200);

10. //columns.Bound(P => P.eqtID).Width(30);

11.

columns.ForeignKey(p => p.eqtID, (System.Collections.IEnumerable)ViewData["EqptTypes"], "TypeID", "Type").Title("Eqpt Type").Width(120);

12.

13. columns.Bound(P => P.eqsID1).Width(30);

14. columns.Bound(P => P.eqsID2).Width(30);

15. columns.Bound(P => P.eqsID3).Width(30);

16. columns.Bound(P => P.peqActive).Width(30);

17. //columns.Command(commands =>

18. //{

19. // commands.Edit();

20. // //commands.Delete().ButtonType(GridButtonType.Image);

21.

22. //}).Width(100);

23.

24. })

25. .ToolBar(toolbar => { toolbar.Create(); toolbar.Save(); })

26. .HtmlAttributes(new { style = "veritcal-align:top" })

27. //.Editable(editable => editable.Mode(GridEditMode.InLine)) // Use inline editing mode.

28. .Editable(editable => editable.Mode(GridEditMode.InCell))

29. .DataSource(dataSource =>

30. dataSource

31. .Ajax()

32. .Batch(true)

33. .Model(model =>

34. {

35. model.Id(P => P.peqID); // Specify the property which is the unique identifier of the model.

36. model.Field(P => P.peqID).Editable(false); // Make the ProductID property not editable.

37. model.Field(P => P.Type).DefaultValue(new PMTWebReconcile.Models.EquipTypeViewModel());

38. })

39.

.Create(create => create.Action("ForeignKeyColumn_Create", "PlantHierArchy")) // Action invoked when the user saves a new data item.

40. // .Read(read => read.Action("ForeignKeyColumn_Read", "PlantHierArchy", new { plsID = (subUnitID) }))

41.

.Update(update => update.Action("ForeignKeyColumn_Update", "PlantHierArchy"))  // Action invoked when the user saves an updated data item.

42. )

43. .Pageable()

44. .Sortable()

45. //.ClientDetailTemplateId

46. )

[Solved] How to remove currency symbol in radnumerictextboxradnumerictextbox

Hi,

I am using Radnumerictextbox with type=currency with different cultures set depending on the requirements. Suppose, if I use culture as "en-US" it is displaying the entered amount with Dollar format. And it also displayes $ symbol at the beginning. But I don't want to display the symbol. So is it possible to set the radnumerictextbox to display the amount without the symbol... Ex : If I enter 1234 , it displays $1.234

I want only amount without $ symbol

Thanks in advance for your answer.

Regards,

Puru

Add Dropdown list to Edit Manager Programatically

I have a RadGrid where the data source is set programmatically because the data source will change based on the option the user selects. Some data sources have more columns than the others. When I have the edit item panel displayed to insert a new record I am removing a text box and adding a drop down in its place and populating the drop down from the database and selecting the value that was in the textbox. I can get this to display but when I click the insert button the page blows up because when the page gets to the init event it wants to bind the old one. any advice on how I can get around this?

here is a ajax error that I get every time I try and do an insert/update

Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
