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. )

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.

Translation of Controls

Hi

I am using the RadGrid control in my website and have a need to translate all the text that the user sees. Is it possible for me to translate the text on the control?

I cant see any way to translate some of the built in text such as "Page Size", "X items in Y Pages" and the search/Filter options that can be accessed by right clicking the grid.

I have attempted to change the culture on the element but this did not appear to make any changes to the language displayed

The Telerik.Web.UI dll version we are using is 2013.2.611.40

Any ideas?

Aggregate="Sum" not working in DetailTable (bug in build 1002)

Hi,

I noticed that Aggregate="Sum" is not working for GridNumericColumn in DetailTables
(build 1002). It gives the error:

Sum is not supported for type "System.Object"

It is working in previous build 724.

Example:

<telerik:RadGrid ClientSettings-AllowDragToGroup="true" ShowGroupPanel="true" ShowFooter="true" runat="server" ID="rg" AutoGenerateColumns="False" GroupPanelPosition="Top">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="id" DataField="id"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="text" DataField="text"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="value" DataField="Value" Aggregate="Sum"></telerik:GridBoundColumn>

</Columns>

<DetailTables>

<telerik:GridTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="id" DataField="id"></telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="text" DataField="text"></telerik:GridBoundColumn>

<telerik:GridNumericColumn HeaderText="value" DataField="value" Aggregate="Sum"></telerik:GridNumericColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

</MasterTableView>

</telerik:RadGrid>

Code behind:

Protected Sub rg_DetailTableDataBind(sender As Object, e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles rg.DetailTableDataBind

Dim dt As New DataTable()

dt.Columns.Add("id", GetType(Integer))

dt.Columns.Add("text", GetType(String))

dt.Columns.Add("value", GetType(Double))

Dim r As DataRow

r = dt.NewRow()

r("id") = "1"

r("text") = "nr. 1 detail"

r("value") = 1.5

dt.Rows.Add(r)

r = dt.NewRow()

r("id") = "2"

r("text") = "nr. 2 detail"

r("value") = 2.5

dt.Rows.Add(r)

e.DetailTableView.DataSource = dt

End Sub

Protected Sub rg_NeedDataSource(sender As Object, e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rg.NeedDataSource

If e.IsFromDetailTable = False Then

Dim dt As New DataTable()

dt.Columns.Add("id", GetType(Integer))

dt.Columns.Add("text", GetType(String))

dt.Columns.Add("value", GetType(Double))

Dim r As DataRow

r = dt.NewRow()

r("id") = "1"

r("text") = "nr. 1"

r("value") = 1.5

dt.Rows.Add(r)

r = dt.NewRow()

r("id") = "2"

r("text") = "nr. 2"

r("value") = 2.5

dt.Rows.Add(r)

rg.DataSource = dt

End If

End Sub
