Within RadEditor if I type words like "test" or "world" the spell checker understands the words and does not show as errors. But If I miss type as "tets" or "wordl" the suggested words list does not have the words test or world in it. But If I type worldd or testt, the suggested words have world or test in it.

for example:

type the below into a radEditor and run SpellChecker....

world worldd wordl test tets testt

Is this a bug or can I tweak the code to do it right?

Filtering/Paging/Finding

I have the following elements on a page: RadComboBox, RadGrid, and an Edit/Insert form. The RadComboBox is used to filter the RadGrid and items selected from the RadGrid populate the edit form. One of the items on the form is the filter value from the RadComboBox.

Scenario #1

Filter the RadGrid

Select an Item from the RadGrid

Edit the item so the Current filter no longer applies.

The result I want:

Reset the RadComboBox to the updated filter value from the form.

Select newly edit item in the RadGrid (Note: This NOT a problem until you add paging to the RadGrid)

Scenario #2

Using the insert form to add a new item

The result I want:

Set the RadComboBox to the newly inserted items filter value.

Select the newly created item in the RadGrid (Note: Again this is NOT a problem until you add paging to the RadGrid)

I guess my basic problem is how to find an item in a paged RadGrid when you don't know what page the item is on. Essentially I want to take an id find out what page it is on, set the correct page index, and select the correct row.

I hope that made sense.

Thanks,

Scott

RadAjaxManager1_AjaxRequest Not Firing

I have RadListBox1 and RadListBox2. They are parked in a RadPageView attached to a RadTab. Either listbox can transfer (move) items from one to the other with the transfer button, 2x-click, or drag-n-drop. Everything is cool. I have a "Save" button, the purpose of which is to update RadListBox2's database table. On button_click I am grabbing the items in RadListBox2 as a collection, parsing the collection, and transforming into a comma-delimited string all on the client in order to pass through RadAjaxManager1_AjaxRequest:

    
            function btnClick() {  
        
                var list = $find("<%= radListBox2.ClientID %>");  
        
                var lstNames = list.get_items();  
        
                var arg;  
        
                if( lstNames.get_count() == 0 ) {  
        
                    if (confirm("blah, blah, blah.\n\nProceed?")) {  
        
                        arg = 0;  
        
                    } else { return 0; }  
        
                } else {  
        
                    arg = lstNames.get_count() + ",";  
        
                    lstNames.forEach( function( item ) { arg = arg + item.get_text() + ","; });  
        
                    arg = arg.substr( 0, arg.length - 1 );  
        
                }  
        
                var ajaxMgr = $find("<%= RadAjaxManager1.ClientID %>");  
        
                ajaxMgr.ajaxRequest( arg );  
        
            }

I have confirmed through JavaScript alerts that all is well here. BUT - ajaxMgr.ajaxRequest( arg ) doesn't fire its associated method in the code-behind. RadScriptManager is set:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

I have Ajax turned on in Page_Load:

    
            RadAjaxManager.GetCurrent( Me ).EnableAJAX = True

I have AutoPostBackOnTransfer turned off on both listboxes because nothing works when switched on:

    
            radListBox1.AutoPostBackOnTransfer = False 
        
            radListBox2.AutoPostBackOnTransfer = False

And the code-behind method looks fine to me:

    
            Protected Sub RadAjaxManager1_AjaxRequest( sender As Object, e As AjaxRequestEventArgs ) Handles RadAjaxManager1.AjaxRequest  
        
                Dim str_Array As String() = Split( e.Argument, "," )  
        
                Dim numRecords = Integer.Parse( str_Array( 0 ))  
        
                Dim lst_Tables As IList( Of String ) = New List( Of String )  
        
                Dim p_data As String = String.Empty   
        
                If numRecords > 0 And numRecords < 10 Then  
        
                    p_data = e.Argument.Substring( 2 )  
        
                ElseIf numRecords > 9 And numRecords < 100 Then  
        
                    p_data = e.Argument.Substring( 3 )  
        
                Else  
        
                    p_data = e.Argument.Substring( 4 )  
        
                End If  
        
                ' sanity check  
        
                RadAjaxManager1.Alert( "numRecords = " & numRecords )  
        
                RadAjaxManager1.Alert( "p_data = " & p_data)  
        
                * * *  
        
            End Sub

But my sanity checks are never invoked.

Got any clues, guys?

Cheers!

RadTabStrip / RadMultiPage state lost when inside nested control in SharePoint web part

Embedding a RadMultiPage / RadTabStrip directly into a SharePoint web part works fine, but for code organization I would like to nest them into a separate control. Once I do this, the control re-creation doesn't work (at least, not the ways I have tried it :)). Specifically, when the RadMultiPage / RadTabStrip are part of the WebPartWithTelerik class (which inherits from System.Web.UI.WebControls.WebParts.WebPart), the RadGrid controls on each page allow editing correctly; however, when they are moved down into the WebPartPanel class, clicking Edit on the RadGrid on either page causes the entire page to re-load, and the controls are not in edit mode as their state has been lost.

Scenario:
* RadTabStrip / RadMultiPage combo with two RadPageView objects.
* Each RadPageView contains a single RadGrid which retrieves data via LinqToSql data sources.
* MOSS web site using VSEWSS 1.3 to build the web part in VS 2008.

I've tried a few iterations of this (attemping to serialize the container object, etc.) with no success. Here's hoping there's a simple fix out there.

Thanks,

William Cook

[Solved] DataSet into RadGrid

Dear friends,

Take a look at the following code:

                    webappteste.WebReferenceX.Service1 sd = new webappteste.WebReferenceX.Service1();         
            DataSet ds = new DataSet();         
            ds = sd.getClientes(); //Get full list of customers from a web service        
            DataTable dt = new DataTable("clientes");         
            dt = ds.Tables[0];         
            RadGrid1.DataSource = dt;         
            int asd = dt.Columns.Count; //Returns 58 columns - CORRECT        
            string tableName = ds.Tables[0].Columns[0].ToString(); //Returns the column name "CLIENTE" - CORRECT        
            int b = ds.Tables[0].Columns.Count; //Returns 58 columns - CORRECT        
            int a = RadGrid1.Columns.Count; //Return 0 columns - WRONG - Why not 58 columns???        

Can you tell me why this is happening?

Is there any other way to load a DataSet into a RadGrid?

Thanks in advance!!

WebService:

[WebMethod]
                    public DataSet getClientes()         
            {         
              SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM CLIENTES ORDER BY    NOME",connections.retConn())         
              DataSet dataSet = new DataSet();         
              dataAdapter.Fill(dataSet);         
              return dataSet         
            }

Turning off Item Data Labels and moving x axis labels

I am having trouble finding the magic setting that disables the item data labels for a line chart, and can't seem to get the x axis label's y position to change to try and move the labels closer to the axis.

ComboBox _ItemsRequested Problem

Hi All,

Here i had used RadComboBox with _itemsrequested property and also total count of the items(i.e Items 1-5 out off 20) in the combobox at the bottom, Their is an issue regarding that (i.e on page load when i click on the combobox for the first time i am unable to get the total count of the combobox items but when i click on the area where i get that message then i will be getting the items message (i.e Items 1-5 out off 20) this message is been placed in the _itemsRequested so i am able to get the items message at the bottom of the combobox so how do i get the items count message on page load when i click on the combobox for first time.

Here is the code

protected void cmbPlatformName_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e){DataTable data = objTaskmanLib.GetData(e.Text); //GetData(e.Text);

//objTaskmanLib is the library file from where i get the count.

RadComboBoxItem item = new RadComboBoxItem();int itemOffset = e.NumberOfItems;int endOffset = Math.Min(itemOffset + ItemsPerRequest, data.Rows.Count);e.EndOfItems = endOffset == data.Rows.Count;for (int i = itemOffset; i < endOffset; i++){cmbPlatformName.Items.Add(new RadComboBoxItem(data.Rows[i]["Platform_Name"].ToString(), data.Rows[i]["Platform_Name"].ToString()));}e.Message = GetStatusMessage(endOffset, data.Rows.Count);}private string GetStatusMessage(int endOffset, int total){if (total <= 0)return "No matches";return String.Format("Items 1-{0} out of {1}", endOffset, total);}

Here i had used this GetStatusMessage function only in the _itemsRequested event so i am able to get the items message(i.e Items 1-5 out off 20) when i click on the area where items message is been displayed. so can any one help me how to use this function on page load also.

Thanks in advance.
