i have the following piece of code:

if (lgSentTo.length > 0) {
var temp = new Array();
// this will return an array with strings "1", "2", etc.
temp = lgSentTo.split(",");
for (a in temp) {
var site = temp[a].toString().trim();
GetRadTreeView().findNodeByText(site).disable();
GetRadTreeView().findNodeByText(site).checked = false;
}
}

while "disable()" works fine, i can't seem to uncheck anything.

i've also tried: GetRadTreeView().findNodeByText(site).uncheck(); but am also getting nowhere. please assist.

Getting text in javascript function

I have a RedEditor with the ID radEditor1 and the following javascript function:

// Character and Word Counter for Telerik RadEditor

// Parameters:

// ID of the RadEditor

// Maximum number of words allowed

// Returns false if maxWords is exceeded, true otherwise

function LimitWordCount(editorId, maxWords)

{

var content = $find(editorId).get_text();

var words = 0;

var chars = 0;

LimitWordCount = true;

if (content) {

punctRegX = /[!\.?;,:&_\-\-\{\}\[\]~#'"]/g;

content = content.replace(punctRegX, "");

if (content) {

splitRegX = /\s+/;

var array = content.split(splitRegX);

words = array.length;

chars = content.length;

}

if (words > maxWords) {

alert("Cannot exceed maximum word count.  Please shorten text.\nTo undo a paste, click the undo button at the top of the text area.")

LimitWordCount = false;

}

I call this function from the following link in a formview:

<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update" Text="Save" CssClass="linkbutton" OnClientClick='LimitWordCount("RadEditor1", 30)' />

When the javascript is hit, $find(editorId) returns null.

How would I get the text in this instance? I have tried all the examples I can find, but all return null or give some other error.

Help is appreciated!

Parent Node Selection

Hi,

I have the latest dll version. Currently we are facing issues with the Treeview control.

When a parent node is selected, all the child nodes get selected but not the Parent node. I have tried with "TriStateCheckboxes = True", unfortunately when I deselect all the child nodes the parent is deselected.

Ex: I have departments and Sub-Departments and I assign employees at all levels. I have to filter on Employees belong to Parent department alone. I select only the Parent Department from the treeview for my filter.

This control was working as expected before we deploy the current dll.

Please treat this on priority.

Thanks.

AJAX not firing up for the first time in SharePoint 2010 Visual webpart

Hi,

I try to create a simple application using Telerik AJAX manager and below is my code:
VisualWebpart.ascx

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server" >

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btn">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="lbl" LoadingPanelID="load1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:label ID="lbl" runat=server />

<asp:Button ID="btn" runat=server Text="press" onclick="btn_Click" />

In my VisualWebpart.ascx.cs

using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

namespace DPA.DPINET.ResourceBooking.View.CalendarVW
{
    public partial class CalendarVWUserControl : UserControl
    {
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            EnsureChildControls();
        }
        protected void Page_Load(object sender, EventArgs e)
        {


        }

        protected void btn_Click(object sender, EventArgs e)
        {
            System.Threading.Thread.Sleep(3000);
            lbl.Text = DateTime.Now.ToString();
        }
    }
}

In my Master Page:

<asp:ScriptManager id="ScriptManager" runat="server" EnablePageMethods="false" EnablePartialRendering="true" EnableScriptGlobalization="false" EnableScriptLocalization="true" />

Inplace Update Not Functioning

Using the various examples of doing inplace editing/updating, I'm running into issues. I have a radgrid that autogenerates the columns depending upon a question the user selects. The page unto itself works fine. The grid gets populated correctly and the inplace editing columns come up just fine. Just nothing updates when I click the "update" button........

FYI - all columns are numeric double values.

The issue I've seen is that at the "For Each Column In e.Item.OwnerTableView.Columns" loop in the update subroutine, it does not cycle, catch, identify, know that, etc. there are columns in the grid. I can have 44 autogenerated columns and this For/Next loop only executes once and then moves on.

Any and all suggestions are more than welcome!

Here is the code on my aspx page:

<telerik:RadGrid ID="rg_GrowthRates" runat="server" AllowSorting="True"

CellSpacing="0" GridLines="None"

AllowFilteringByColumn="True" Width="100%"

AllowPaging="True" PageSize="15"

EnableViewState="False" ViewStateMode="Disabled" Skin="Metro"

AllowAutomaticUpdates="True" AutoGenerateEditColumn="True">

<MasterTableView DataKeyNames="ID_SurveyInstitutional" EditMode="InPlace" >

<CommandItemSettings ShowAddNewRecordButton="False" />

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn1 column" UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

<EditItemStyle BackColor="LightSteelBlue" BorderColor="Black" BorderStyle="Dashed" BorderWidth="1px" HorizontalAlign="Center" VerticalAlign="Middle" Width="50px" />

<PagerStyle AlwaysVisible="True" PageSizes="15;30;45;60;All" />

<CommandItemStyle BackColor="#FFFFC0" />

</MasterTableView>

<PagerStyle AlwaysVisible="True" PageButtonCount="15" PageSizes="15;30;45;60;All" />

</telerik:RadGrid>

In my code behind I have this as my grid source:

Private ReadOnly Property GridSource As DataTable

Get

Dim obj As Object = Me.ViewState("_gds")

If (Not obj Is Nothing) Then

Return CType(obj, DataTable)

Else

querystring = "SELECT ID_SurveyInstitutional, " & getDatabaseColumns(Session("selectedQuestion")) & " " & _

"FROM SurveyInstitutional " & _

"WHERE ID_AvailableQuarters = " & Session("selectedQuarter")

RERCDataCenterConnection.Open()

Dim existingCommand As New SqlCommand(querystring, RERCDataCenterConnection)

Dim da As New SqlDataAdapter(existingCommand)

Try

da.Fill(questionTable)

Catch ex As Exception

Finally

RERCDataCenterConnection.Close()

End Try

Me.ViewState("_gds") = questionTable

Return questionTable

End If

End Get

End Property

My "getDatabaseColumns" routing (called above) populates the query depending upon the question the user has selected:

Function getDatabaseColumns(ByVal whichQuestion As Integer)

Dim columnList As New DataTable

Dim columnString As String = ""

querystring = "SELECT DatabaseColumn FROM Const_InstitutionalColumnMatrix WHERE ID_Const_EditableQuestions = " & whichQuestion

RERCDataCenterConnection.Open()

Using getColumns As New SqlCommand(querystring, RERCDataCenterConnection)

Dim da As New SqlDataAdapter(getColumns)

Try

da.Fill(columnList)

Catch ex As Exception

Finally

RERCDataCenterConnection.Close()

End Try

End Using

For Each row As DataRow In columnList.Rows

columnString = columnString & row("DatabaseColumn") & ", "

Next

columnString = Left(columnString, Len(columnString) - 2)

Return columnString

End Function

This is my 'needDataSource':

Private Sub rg_GrowthRates_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles rg_GrowthRates.NeedDataSource

' If they select "Select a Question from the dropdown then clear the grid

If CInt(Session("selectedQuestion")) < 1 Then

rg_GrowthRates.DataSource = New String() {}

Exit Sub

End If

rg_GrowthRates.DataSource = Me.GridSource

End Sub

This is my update routine:

Private Sub rg_GrowthRates_UpdateCommand(sender As Object, e As GridCommandEventArgs) Handles rg_GrowthRates.UpdateCommand

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

Dim currentID As String = item.GetDataKeyValue("ID_SurveyInstitutional").ToString()

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim editMan As GridEditManager = editedItem.EditManager

Dim column As GridColumn

For Each column In e.Item.OwnerTableView.Columns

If TypeOf column Is IGridEditableColumn Then

Dim editableCol As IGridEditableColumn = CType(column, IGridEditableColumn)

If (editableCol.IsEditable) Then

Dim editor As IGridColumnEditor = editMan.GetColumnEditor(editableCol)

Dim editorText As String = ""

Dim editorValue As Object = Nothing

If (TypeOf editor Is GridTextColumnEditor) Then

editorText = CType(editor, GridTextColumnEditor).Text

editorValue = CType(editor, GridTextColumnEditor).Text

End If

If (TypeOf editor Is GridBoolColumnEditor) Then

editorText = CType(editor, GridBoolColumnEditor).Value.ToString()

editorValue = CType(editor, GridBoolColumnEditor).Value

End If

If (TypeOf editor Is GridDropDownColumnEditor) Then

editorText = CType(editor, GridDropDownColumnEditor).SelectedText + "; " + CType(editor, GridDropDownColumnEditor).SelectedValue

editorValue = CType(editor, GridDropDownColumnEditor).SelectedValue

End If

Try

Dim changedRows As DataRow() = Me.GridSource.Select("ID_SurveyInstitutional = " + editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)("ID_SurveyInstitutional").ToString())

changedRows(0)(column.UniqueName) = editorValue

Me.GridSource.AcceptChanges()

Catch ex As Exception

e.Canceled = True

End Try

processEdits(column.UniqueName, editorValue, currentID)

End If

Next

rg_GrowthRates.MasterTableView.ClearEditItems()

End Sub

And finally, my 'processEdits' routine:

Protected Sub processEdits(ByVal columnName As String, ByVal newVal As String, ByVal currentID As Integer)

Dim valueToUpdate As Double

If Not IsDBNull(newVal) And Trim(newVal) <> "" Then

valueToUpdate = CDbl(newVal)

querystring = "UPDATE SurveyInstitutional " & _

"SET " & columnName & " = " & valueToUpdate & " " & _

"WHERE ID_SurveyInstitutional = " & CInt(currentID)

Else

RERCDataCenterConnection.Close()

Exit Sub

End If

RERCDataCenterConnection.Open()

Dim processEditAction As New SqlCommand(querystring, RERCDataCenterConnection)

processEditAction.ExecuteNonQuery()

RERCDataCenterConnection.Close()

rg_GrowthRates.EditIndexes.Clear()

rg_GrowthRates.Rebind()

End Sub

MasterPage causing Server Error

Hi,



I have a Problem with the Telerik AsyncUpload Control. I'm using VS2010 Pro.



When I'm using this control in a single Webpage it works:



<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>

</telerik:RadProgressArea>

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Upload" />

</form>

</body>

</html>

when I'm adding a masterpage it throws me an error (see screenshot).
Here is the Code of the masterpage:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebAppTelerik2.Site1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<div>

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</div>

</form>

and the code of the contentpage:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebAppTelerik2.ChildPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</Scripts>

</telerik:RadScriptManager>

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" ChunkSize="0">

</telerik:RadAsyncUpload>

</asp:Content>

Do anyone have an idea whats the Problem.

I don't understand, why it's throwing the error and why it wants to load a SharePoint assembly...

Edit:
I do have SharePoint Foundation and SQL Express installed on the dev machine, but I think this shouldn't have something to do with this Problem.

Thanks for your help
