Simple server-side row selecting and accessing row data

I've been searching through the documentation to do a simple server-side select and access the data in that row. I found this page here (http://www.telerik.com/help/aspnet-ajax/grid-retrieve-primary-key-field-values-for-items.html) and used a line from the sample code:

RadGrid1.SelectedItems[0].GetDataKeyValue("CustomerID").ToString()

Visual Studio gives me an error of "'Telerik.Web.UI.GridItem' does not contain a definition for 'GetDataKeyValue' and no extension method 'GetDataKeyValue' accepting a first argument of type 'Telerik.Web.UI.GridItem' could be found (are you missing a using directive or an assembly reference?)"

I tried a different route using this:

grd.SelectedItems[0].Cells[1].Text

but this doesn't return anything at runtime, regardless of the index I use for the cells collection.

Please advise. Thanks guys!

[Solved] How to insert a value the RadNumericTextBox to RadSlider?

The project got a RadSlider, a RadNumericTextBox and a Label. Changing values RadSlider the value shown in RadNumericTextBox, Label displays the function result (deposit + interest).

The problem is that I can not create an event that would change the values in RadNumericTexBox (change clients) value delegated to RadSlider.

<script type="text/javascript">

GridTemplateColumn checkbox uncheck another checkbox in row

What I am trying to do is uncheck another checkbox in the same row. I want to have a subscribe and unsubscribe checkbox columns. So when you click on subscribe the unsubscribe checkbox should uncheck and vise versa. I found a lot of entries that are similar in the forums but didnt come across anything in this.

Private Sub grdPubList_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles grdPubList.ItemCreated

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim chk1 As CheckBox = DirectCast(item.FindControl("radchkSubscribe"), CheckBox)

Dim chk2 As CheckBox = DirectCast(item.FindControl("radchkUnsubscribe"), CheckBox)

'Dim chk3 As CheckBox = DirectCast(item.FindControl("CheckBox3"), CheckBox)

chk1.Attributes.Add("onclick", (("checkUncheck('" + chk1.ClientID & "','") + chk2.ClientID & "',')"))

End If

End Sub

Javascript in masterpage. Though i think the ch2.checked should be false in the if and true in the else.

<script type="text/javascript">

function checkUncheck(c1, c2) {

var ch1 = document.getElementById(c1);

var ch2 = document.getElementById(c2);

if (ch1.checked) {

ch2.checked = true;

}

else {

ch2.checked = false;

}

How do I get combobox type in javascript

I have a switch statement in a javascript function that performs different actions based on the type of control that is being passed, however the sender.type of the RadComboBox is null. How do I get the type?

here is my javascript function:

function RefreshCsiOptions(sender) {

switch (sender.type) {

case "radio":

if (sender.checked == true) {

for (i = 0; i < cbxCSI.length; i++) {

var z = rcbCSI[i];

if (rcbCSI[i].get_selecteditem().get_value() != "") { rcbCSI[i].disabled = "disabled"; } else { cbxCSI[i].disabled = true; }

cbxCSI[i].checked = false;

}

lblWithoutCSI.disabled = "";

}

break;

case "checkbox":

var cbxNumber = sender.id.substr(6, 1);

if (sender.checked == true) {

rcbCSI[cbxNumber - 1].disabled = "";

lblWithoutCSI.disabled = "disabled";

rbWITHOUT.checked = false;

} else {

rcbCSI[cbxNumber - 1].disabled = "disabled";

}

CheckWithoutStatus();

break;

case "select-one":

var rcbNumber = sender.id.substr(14, 1);

if (rcbNumber == "_") rcbNumber = "0";

var rcbValue = rcbCSI[rcbNumber].get_selecteditem().get_value();

document.Form1.elements['CSI' + rcbNumber + '_value'].value = rcbValue;

if (rcbValue != "") {

cbxCSI[rcbNumber].disabled = false;

cbxCSI[rcbNumber].checked = true;

if (rbWITHOUT.checked == true) rbWITHOUT.checked = false;

} else {

cbxCSI[rcbNumber].disabled = true;

cbxCSI[rcbNumber].checked = false;

CheckWithoutStatus();

}

break;

default:

//alert(sender.type);

break;

}

Resources and grouping

Hi! There is a radscheduler whose datasource is a list of appointments, each of them having one or more resources. (There is many-to-many relationship between appointments and resources). Also, there is a checkboxlist of resources, used for binding resurce type of a scheduler. How can I group scheduler by that resource type, to look like in your example on http://demos.telerik.com/ASPNET/Prometheus/Scheduler/Examples/ResourceGrouping/DefaultCS.aspx? (I would like it to have as many columns as number of boxes cheked in checkboxlist). As I understod, relationsheep should be one-to-many or I have to set some appointmentProviders in webconfig?

This is what a have:

<

telerik:RadScheduler runat="server" ID="RadScheduler1" Skin="<%$ AppSettings: SchedulerSkin%>"Width="750px" StartEditingInAdvancedForm="false" SelectedView="MonthView" DataKeyField="ID"DataSubjectField="Subject" DataStartField="Start" DataEndField="End" DataRecurrenceField="RecurrenceRule"DataRecurrenceParentKeyField="RecurrenceParentID" EnableEmbeddedSkins="true" OverflowBehavior="Expand">
<ResourceTypes><telerik:ResourceType TextField="Naziv" KeyField="ResursID" Name="Resurs"/>
</ResourceTypes></telerik:RadScheduler>

I bind scheduler in code behind, and I want to do that with the resource type to, as simplier as it can be. Please help. Thanks,
Ana

[Solved] Apply GridCalculatedColumn's Expression to its Footer

I have a grid that is programmatically created in Page_Load that also includes a varying number of calculated columns. Each column contains an aggregate (count, sum, etc.). However, one of my columns is a percentage that is calculated based on other bound columns. Each row's calculation is done perfectly, but the grid footer should apply the same expression to the rest of the footer's values. The real trick is that the expression being used by the grid is not known at design time so I am unable to manually create a custom aggregate.

Anyone have any ideas how I can use the expression and datafields from the GridCalculatedColumn to evaluate that column's footer?

The way of working is the next, when selecting a item from TaskRadGridView, we load data from the database:

Protected Sub TasksRGriVie_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)

Dim AuxTaskId As Integer

If TasksRGriVie.SelectedItems.Count > 0 Then

Dim item As GridDataItem = TasksRGriVie.SelectedItems(0)

AuxTaskId = CInt(item.GetDataKeyValue("taskID"))

LoadTaskDetails(AuxTaskId)

End If

End Sub

Sub LoadTaskDetails(ByVal selTaskID As Integer)

If TasksRGriVie.Items.Count > 0 Then

Dim auxQual As Integer = CInt(Me.SelQualHidFie.Value)

Dim curContractor As Integer = Session("CompanyID")

Dim objtask As OQCrewItem = listTask.Find(Function(c) c.taskID = selTaskID)

'Loads the list view with the current personnal

Dim ListPerAs As New List(Of OQCrewPersonnel)

'Getting data from the view state

If selTaskID > 0 Then

'listTask a property that gets data from viewState('listtask')

ListPerAs = listTask.Find(Function(c) c.taskID = selTaskID).personnel

PersonnelAssignedRTreLst.DataSource = ListPerAs.Where(Function(c) c.statusID = 1).OrderByDescending(Function(c) c.lastName).ToList()

End If

'Gets list of personnel

Dim listAvailablePer = OQProjectBL.GetAvailableCrewPersonnel()

Dim list = listAvailablePer.Where(Function(c) c.qualified = "Yes").OrderBy(Function(c1) c1.lastName).ToList()

PersonnelToAssignRGriVie.DataSource = list

PersonnelToAssignRGriVie.DataBind()

End If

End Sub

The when we select (highlight) a node from the RadTreeList PersonnelAssignedRTreLst, we get the data for PersonnelToAssignGriView, from the PersonnelToAssignGriView we can select (check) several items then when we click on the button PersonnelAddRBtn
on the header of this item we should add those items to PersonnelAssignedRTreLst, the problem occurs when the list of items related to the PersonnelToAssignGriView is like 500 rows, there is a problem when click on the PersonnelAddRBtn
Button from the header, it does not make a postback I get this error. Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. It doesn't make a postback, I search in the web, I'm not using Response.write anywhere. Thinking that the problem could be that the button is inside the radajaxpanel i set a button Add on the RadToolBar, but i get a similar error, it never goes to the function established on the serverside, i set a debugger on the JS function selBut that executes onClientButtonClicking event, then i got an exception on telerik code on line 6224 see that on image related.
There is another odd behavior of the page, in some computers there isn't any exception, could be a configuration that i'm missing?.

RadChart Month Name on XAxis

Hello there,

I am getting two columns from database (using SQL Data Source) namely points and month, I am summing the points based on month number for example a person gained 500 points in month 6 (which means June). The data appears in this format.

500, 6
1100, 7
900, 8
430 9

and so on...

Now I am binding the points (the first column) to y-axis of rad chart and month number to x-axis. But I want x-axis values to appear as month names instead of numeric values like June or Jun for 6, July or Jul for 7 and so on...

How can I convert xaxis numeric values to month names ?

Thanks.

How to ajaxify a multiview that contains a RadScheduler and GridView?

I have a MultiView control, and on View2 I have several LinkButtons, GridView, RadScheduler and RadListBox with check boxes on every item. I want to be able to update the whole View2 on RadScheduler_AppointmentUpdate event. How can I accomplish that? I've used RadAjaxManager and have set AjaxControlID="RadScheduler" . For AjaxUpdatedControl I've set View2 and got the error: "Controls added to a ViewCollection must be of type View"
On THIS thread you said that I should wrap the whole MultiView with a Panel. But after I do that, I'm not able to check any checkbox inside RadListBox. Edit: Checking RadListBox items is essential for populating appointments in RadScheduler.
Is it possible to refresh a MultiView's view on RadScheduler_AppointmentUpdate event?
