No data displaying

Hi,

I am using version 2015.1.401.40 of your asp.net for ajax controls.

I've never used the PivotGrid, but I am experimenting with it now and I don't see any data after binding it.

Here is the markup of the grid:

<telerik:RadPivotGrid ID="AlertsRadPivotGrid" runat="server">

<telerik:PivotGridColumnField DataField="AlertLevel" UniqueName="AlertLevel" />

<telerik:PivotGridRowField DataField="SupplierCompanyName" UniqueName="SupplierCompanyName" />

<telerik:PivotGridAggregateField DataField="AlertID" UniqueName="AlertID" Aggregate="Count" />

</Fields>

</telerik:RadPivotGrid>

Here is my code:

Private Sub AlertsRadPivotGrid_NeedDataSource(sender As Object, e As Telerik.Web.UI.PivotGridNeedDataSourceEventArgs) Handles AlertsRadPivotGrid.NeedDataSource

Dim scAlerts As List(Of SupplierAlert)

Dim scAlertList As SupplierAlertList = New SupplierAlertList

scAlerts = scAlertList.GetHarmonyAlertDetailsData("129052", 8939, New Date(2015, 3, 1), New Date(2015, 10, 1), SessUserCultureCode)

AlertsRadPivotGrid.DataSource = scAlerts

End Sub

So, I'm binding to a Generic List of a strongly typed object (class) that I've created. When the code runs, the NeedDataSource method runs and the scAlerts object above has 240 SupplierAlert items in it.

I see bind to strongly typed lists, so I assume it is possible.

When I run it I see a PivotGrid with my column and row, but there is no data / detail displayed.

Am I doing something wrong?

AlertLevel is an integer

SupplierCompanyID is a string

AlertID is an integer

There are no nulls in any of my data.

Thanks,
Brent

[Solved] Select Row on GridButtonColumn click

Perhaps this is by design, but it seems that if you set the client setting AllowRowSelect="true", the row is not selected when you click on a GridButtonColumn. For example, I have a GridButtonColumn for Delete, and if I select a row, it is selected, but then if I press the Delete button on a different row, the previous row is still selected. When I use ConfirmText, it could be confusing to the user since they might think they are about to delete the selected row instead of the row they clicked the delete button on.

Is there an easy way to have the row selected that the GridButtonColumn was pressed in?

RadGrid1_RowDrop is being Executed on Page Reload Unnecessarily

Hi, I have a page (SiteScheduler.aspx) with a RadGrid and a RadScheduler on it and I followed the online examples of how to drag and drop rows from the RadGrid to the RadScheduler - and it works perfectly. I wired up a RadWindow to open from a ContextMenu - and the RadWindow, which is modal and appears over SiteScheduler.aspx, allows the user to change the assigned staff person to the appointment in the scheduler. Here again, that functionality works great. My staff person reassignment correction is made. When the RadWindow closes, it executes document.location.reload() to refresh SiteScheduler.aspx.

My problem I ran into yesterday and still today is that if I had dragged a row from the RadGrid to the Scheduler prior to right clicking and open the RadWindow to reassign the staff person, the RadGrid1_RowDrop event is executed again on the document.location.reload() (or F5 for that matter). This causes an incorrectly scheduled staff person. It's like the RowDrop is still 'remembering' the prior drop action and even the same row that was dragged before to the RadWindow opening.

If I do not drag a row from the grid to the scheduler before right clicking to open the RadWindow to reassign the staff person, the RadGrid1_RowDrop event is not executed and it works as required.

Here are a couple of things I tried:

1. Thought it might be cache related so I turned off client side caching by placing this in Page_load

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.Now);
Response.Cache.SetNoServerCaching();
Response.Cache.SetNoStore();

2. Because of the way the page works , I had to set EnableAJAX="False" in the RadAjaxManager. I would love to be able refresh just the scheduler but don't know how to do this with EnableAJAX="False" being set.

3. I tried to simulate the click event of a button that refreshes and rebinds the scheduler however the button does not exist in the RadWindow close event (as the form's controls are not present yet) so it does not work.

Is there something I am missing or do you have any suggestions? Is there a way to 'Cancel' or dispose of the prior RadGrid RowDrop event once it is complete so it is not executed again?

Here is my RadGrid definition if it helps:

<telerik:RadGrid runat="server" ID="RadGrid1" Skin="Metro" Style="border: none; outline: 0;"
AllowAutomaticInserts="True" AllowAutomaticUpdates="True" Height="800px"
AllowAutomaticDeletes="True" MasterTableView-DataKeyNames="StaffId" OnItemCommand="RadGrid1_ItemCommand"
OnItemCreated="RadGrid1_ItemCreated" OnRowDrop="RadGrid1_RowDrop" OnRowDropped="RadGrid1_RowDropped" AutoGenerateColumns="False" PageSize="30" RenderMode="Lightweight" Width="100%"
RetainExpandStateOnRebind="True" ClientSettings-AllowAutoScrollOnDragDrop="False">
<ClientSettings AllowRowsDragDrop="True">
<Selecting AllowRowSelect="True"></Selecting>
<ClientEvents OnRowDropping="rowDropping" OnRowDblClick="onRowDoubleClick"></ClientEvents>
<Scrolling AllowScroll="True" ScrollHeight="800px" UseStaticHeaders="True" />
</ClientSettings>
<MasterTableView DataKeyNames="StaffId" RetainExpandStateOnRebind="True">
<RowIndicatorColumn Visible="False">
</RowIndicatorColumn>
<Columns>
<telerik:GridBoundColumn DataField="StaffFullName" FilterControlAltText="Filter colStaffname column" Groupable="False" HeaderText="Staff Name" ReadOnly="True" Reorderable="False" UniqueName="colStaffname" HeaderTooltip="skdj">
</telerik:GridBoundColumn>
</Columns>
</MasterTableView>
<FilterMenu RenderMode="Lightweight"></FilterMenu>
<HeaderContextMenu RenderMode="Lightweight"></HeaderContextMenu>
</telerik:RadGrid>

Thanks for any help you can provide.

Open Child Window from dynamically created LinkButton Attributes

Hi

Please bear with me I'm quite new to Teleik. My scenario is I have a RadGrid which is built completely in C# code because the columns can vary. Each data bound field is either a link button or a label. For the link button I want to be able to open a child window which contains a RadGrid displaying the drill down data of the selected link button.

This is the code which builds the main RadGrid:

001.private Control DefineGridStructure(DataTable InGrid)

002. {

003. RadGrid grid = new RadGrid();

004. grid.ID = "RadGridDetail";

005. grid.DataSource = InGrid;

006. grid.Skin = "Outlook";

007. grid.Width = Unit.Percentage(100);

008. grid.AllowPaging = false;

009. grid.AutoGenerateColumns = false;

010. grid.MasterTableView.Width = Unit.Percentage(100);

011. grid.HeaderStyle.Font.Size = 10;

012. grid.HeaderStyle.Font.Bold = true;

013. grid.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

014.

015. try

016. {

017. grid.MasterTableView.DataKeyNames = new string[] { InGrid.Columns[1].ColumnName };

018.

019.

020. GridBoundColumn Col1 = new GridBoundColumn();

021. Col1.DataField = InGrid.Columns[0].ColumnName;

022. //GridBoundColumn Col2 = new GridBoundColumn();

023. //Col2.DataField = InGrid.Columns[1].ColumnName;

024.

025. if (InGrid.Columns[0].ColumnName == "PDESC")

026. {

027. Col1.HeaderText = "Problem Description";

028. //Col2.HeaderText = "Problem Code";

029. }

030. else

031. {

032. Col1.HeaderText = "Region";

033. }

034. grid.Columns.Add(Col1);

035.

036. //Col3 - Query

037. GridTemplateColumn Col3 = new GridTemplateColumn();

038. Col3.ItemTemplate = new MyTemplate("Query", "£'s Val", "In Qry");

039. Col3.HeaderText = "Query";

040. grid.Columns.Add(Col3);

041.

042. //Col4 - 90D

043. GridTemplateColumn Col4 = new GridTemplateColumn();

044. Col4.ItemTemplate = new MyTemplate("D90", 4, "lnk");

045. Col4.HeaderText = "90+ Days";

046. grid.Columns.Add(Col4);

047.

048. //Col5 - Month 3

049. GridTemplateColumn Col5 = new GridTemplateColumn();

050. Col5.ItemTemplate = new MyTemplate("M3", 5, "lnk");

051. Col5.HeaderText = Utils.GetMonth(3) + "-" + Utils.GetYear(3);

052. grid.Columns.Add(Col5);

053.

054. //Col6 - Month 2

055. GridTemplateColumn Col6 = new GridTemplateColumn();

056. Col6.ItemTemplate = new MyTemplate("M2", 6, "lnk");

057. Col6.HeaderText = Utils.GetMonth(2) + "-" + Utils.GetYear(2);

058. grid.Columns.Add(Col6);

059.

060. //Col7 - Month 1

061. GridTemplateColumn Col7 = new GridTemplateColumn();

062. Col7.ItemTemplate = new MyTemplate("M1", 7, "lnk");

063. Col7.HeaderText = Utils.GetMonth(1) + "-" + Utils.GetYear(1);

064. grid.Columns.Add(Col7);

065.

066. //*****Building dynamic number of weeks column******

067. DataTable NumWeeks = Utils.GetDataTable("SELECT * FROM [dbo].[fn_GetNumWeeks]() ORDER BY intWEEK ASC");

068. int numOfWeeks = NumWeeks.Rows.Count;

069.

070. for (int i = 1; i < (numOfWeeks + 1); i++)

071. {

072. int columnNo = 7 + i;

073. GridTemplateColumn Cols = new GridTemplateColumn();

074. Cols.ItemTemplate = new MyTemplate("Wk" + i, columnNo, "lnk");

075. Cols.HeaderText = Utils.GetMonth(0) + "<br/> " + "Week " + i;

076. grid.Columns.Add(Cols);

077. }

078. //*************************************************

079.

080. //Col13 - MTD

081. GridTemplateColumn Col13 = new GridTemplateColumn();

082. Col13.ItemTemplate = new MyTemplate("MTD", 13, "lnk");

083. Col13.HeaderText = "MTD";

084. grid.Columns.Add(Col13);

085.

086. //Col14 - YTD

087. GridTemplateColumn Col14 = new GridTemplateColumn();

088. Col14.ItemTemplate = new MyTemplate("YTD", 14, "lbl");

089. Col14.HeaderText = "YTD";

090. grid.Columns.Add(Col14);

091.

092. //Col15 - OO/S

093. GridTemplateColumn Col15 = new GridTemplateColumn();

094. Col15.ItemTemplate = new MyTemplate("OOS", 15, "lbl");

095. Col15.HeaderText = "Overall <br/> Outstanding";

096. grid.Columns.Add(Col15);

097.

098. //Col16 - % OS Vs OV

099. GridTemplateColumn Col16 = new GridTemplateColumn();

100. Col16.ItemTemplate = new MyTemplate("Pct", 16, "lbl");

101. Col16.HeaderText = "% Of Outstanding <br/> Vs Overall";

102. grid.Columns.Add(Col16);

103.

104. ShowResult.Controls.Add(grid);

105. }

106. catch

107. {

108. //No records found.

109. }

110. return grid;

111.

112. }

The columns are generated using Templates:

01.Label[] lblVal = new Label[17];

02. Label[] lblQty = new Label[17];

03.

04. LinkButton[] lnkVal = new LinkButton[17];

05. LinkButton[] lnkQty = new LinkButton[17];

06.

07. public MyTemplate(string cName, int typeID, string clinkOrLabel)

08. {

09. ID = typeID;

10. templateType = cName;

11. colname = cName;

12. linkOrLabel = clinkOrLabel;

13. Params = 3;

14. }

And finally, this is the InstantiateIn code which creates the grid and prints it to the screen:

01.public void InstantiateIn(Control container)

02. {

03. Literal lc = new Literal();

04. lc.Text = "<hr style='border: 1px;border-style: dotted;'/>";

05.

06. if(templateType == "Query")

07. {

08. Label lblValQ = new Label();

09. lblValQ.ID = colname + "Val";

10. Label lblQtyQ = new Label();

11. lblQtyQ.ID = colname + "Qty";

12. lblValQ.Font.Size = 9;

13. lblQtyQ.Font.Size = 9;

14.

15. if (Params == 3)

16. {

17. lblValQ.Text = ValCnt;

18. lblQtyQ.Text = QtyCnt;

19. }

20. container.Controls.Add(lblValQ);

21. container.Controls.Add(lc);

22. container.Controls.Add(lblQtyQ);

23. }

24. else

25. {

26. //decided whether the field should be a link button or a label

27. if (linkOrLabel == "lnk")

28. {

29. lnkVal[ID] = new LinkButton();

30. lnkVal[ID].DataBinding += lnkVal_DataBinding;

31. lnkVal[ID].Attributes.Add("OpenWindow", "openChildWindow(4,31,99);");

32. lnkQty[ID] = new LinkButton();

33. lnkQty[ID].DataBinding += lnkQty_DataBinding;

34. lnkQty[ID].Attributes.Add("OpenWindow", "openChildWindow(4, 31,99);");

35.

36. container.Controls.Add(lnkVal[ID]);

37. container.Controls.Add(lc);

38. container.Controls.Add(lnkQty[ID]);

39. }

40. else

41. {

42. lblVal[ID] = new Label();

43. lblVal[ID].DataBinding += lblVal_DataBinding;

44. lblQty[ID] = new Label();

45. lblQty[ID].DataBinding += lblQty_DataBinding;

46.

47. container.Controls.Add(lblVal[ID]);

48. container.Controls.Add(lc);

49. container.Controls.Add(lblQty[ID]);

50. }

51. }

52. }

I am attempting to add Attributes to all the linkbuttons which will send to the javascript displayed below to get the data for the new window.

1.<script type="text/javascript" language="javascript">

2. function openChildWindow(Period, SalesMn, intWeek, ReasCode) {

3. window.open('RadGridExportWebForm.aspx?Period=' + Period + '&SalesMn=' + escape(SalesMn) + '&intWeek=' + intWeek + '&ReasCode=' + ReasCode, 'childWindow', 'width=800,height=600,scrollbars=1,menubar=0,status=0,toolbar=0,resizable=1,titlebar=0', false);

4. };

5. </script>

However what is actually happening is the current page is simply reloading, it's not creating or opening a new window as I want it to.

I hope this makes sense

Any help would be greatly appreciated.

Many thanks!

Drag and drop

is possible to re size RadDockZone to either 320 x 270px or 640 x 270px?

Then, allow the user to add new RadDockZones dynamically when an "add zone" button is clicked?

Column Widths

Hi,

Having recently installed the new Q2 2015 SP1 version of the controls I have noticed that some of my grids behave differently. Before if columns didn't have a specific width they'd expand to fill the width of the grid. Now they don't.

Any suggestion on what change could be causing this behavior?

Regards

Jon
