Ajaxifying controls in templates

What is the proper procedure to ajaxify controls contained in layout templates of RadGrids or Formviews?

e.g. if RadFormView1 contains an itemtemplate which contains a RadGrid, how does one properly configure the RadAjaxManager to ajaxify the grid?

I tried something like this:

01.<telerik:RadAjaxManager runat="server" ID="RadAjaxManager_ManualRequest">
02.    <AjaxSettings>
03.      <telerik:AjaxSetting AjaxControlID="RadFormView_Customers">
04.        <UpdatedControls>
05.          <telerik:AjaxUpdatedControl ControlID="RadFormView_Customers" LoadingPanelID="RadAjaxLoadingPanel_ManualRequest" />
06.        </UpdatedControls>
07.      </telerik:AjaxSetting>
08.      <telerik:AjaxSetting AjaxControlID="RadGrid_Addresses">
09.        <UpdatedControls>
10.          <telerik:AjaxUpdatedControl ControlID="RadGrid_Addresses" LoadingPanelID="RadAjaxLoadingPanel_ManualRequest" />
11.        </UpdatedControls>
12.      </telerik:AjaxSetting>
13.    </AjaxSettings>
14.  </telerik:RadAjaxManager>

 

Using this definition (where Radgrid_Addresses is a control contained in the ItemTemplate of the Formview), the ajax request seems to work for the first request to the radgrid (for example, moving to the next page) but subsequent requests (moving back or forward a page again) seem to affect the entire formview rather than just the grid.

 

Thanks,

Stacked Column series border and styles

Hi,

We are using a stacked column series for our chart display. We have a single stacked bar in display (as attached). I am trying to add a border to each stack/column but I couldn't find an attribute I can use. I tried the approach defined here but that didn't seem to work.

https://feedback.telerik.com/aspnet-ajax/1373488-add-appearance-options-for-the-series-border-in-radhtmlchart

Another thing that I am having to struggle with is I have the chart title visible set to false but there is a white space in that area that I can't seem to get rid of. Is there somewhere in css i can do that?

Attached is the expected and what I see right now. I gave the chart a black background to show what I mean.

Can you help me figure this out?

Saving RadSpreadsheet freezes when amount of data is big

I have implement a custom provider for RadSpreadsheet as follows:

 

public class MySpreadsheetDocumentProvider : SpreadsheetProviderBase
{
public string FilePath { get; set; }
 
      public MySpreadsheetDocumentProvider(APD apd, out string errorMessage) : base()
{
   errorMessage = string.Empty;
   string folderPath = $"{ConfigurationManager.AppSettings["SpreadsheetFolder"]}";
 
 if (!Directory.Exists(folderPath))
 {
   Directory.CreateDirectory(folderPath);
 }
              
  FilePath = $"{folderPath}/{apd.APDId}.xlsx";
 
  if (!File.Exists(FilePath))
  {               
     Workbook workbook = new Workbook();
     Worksheet worksheet = workbook.AddSheet();                
 
     using (APD_BLL apd_bll = new APD_BLL())
     {
        var apd_data = apd_bll.Get(apd.APDId);
        FillWorksheet(worksheet, apd_data);
     }
 
     workbook.Save(FilePath);
  }           
   }
 
public override void SaveWorkbook(Workbook workbook)
   {
   SpreadsheetDocumentProvider provider = new SpreadsheetDocumentProvider(FilePath);
   provider.SaveWorkbook(workbook);
   }
 
public override List<Worksheet> GetSheets()
   {
    SpreadsheetDocumentProvider provider = new SpreadsheetDocumentProvider(FilePath);
    var sheets = provider.GetSheets();
 
    return sheets;
 }
 
 private static void FillWorksheet(Worksheet sheet, IEnumerable<APDYpallhlou> data)
 { 

  .....

 }

 

So the provider looks for an excel file in a predefined location. If the file exists then it is bound to the RadSpreadsheet, otherwise a new file is created. This part of the provider works well with small as well as with bigger files.

The problem is when I try to Save the RadSpreadsheet by clicking the Save button on the toolbar. Save works ok for a few hundred rows. But it fails for a larger number of rows, e.g. 15000 rows. When the Save button is clicked the page freezes and method SaveWorkbook(Workbook workbook) is never invoked.

Radgrid template column paging get all data

Hi,
I am using the textbox, RadNumericTextBox and RadAutoCompleteBox inside the grid to receive the values and store them in the DB. However, when a lot of data needs to be input, the speed of binding becomes slower, so virtualization and paging are performed. So, there is a problem of turning the loop to get the data of the grid and not getting the entire data.

RadGridItems.AllowPaging = false; RadGridItems.Rebind(); I need to get the data entered in needdatasource at the time, but I don't know how to get it. Please tell me how to get all the data entered on the paged grid. Please help me its urgent issue.please refer code below.

Paging is not working if I rebind the grid.
Hi
I'm using radrgid in my application inside the radpanelbar as one of the radpanelitem.
I need to get the data from database on regular interval of 2 minutes and need to show in grid without need of refreshing the page.
For the I'm using Timer and updating the panelbar using asp:updatepanel with conditional updatemode and calling needdatasource event from pageload for every 2 minutes.
So to have the chages on interval basis I'm rebing the grid.
But paging is not working. If I dnt rebind the grid I'm not able to see the new chages.
 here is my code of needdatasource event
DataTable dtConsole = new DataTable();
       DataAccess accessData = new DataAccess();
       try
       {
           dtConsole = accessData.GetData("select consolename from CONSOLE");
           consloeGrid.DataSource = dtConsole;
           //if I dont rebind new data not showing else paging is not working
           consloeGrid.Rebind();
           if (dtConsole.Rows.Count > 10)
           {
               consloeGrid.AllowPaging = true;
           }
       }
Please help me as early as possible.
