Hello Team,

As soon as RadPivotGrid's width increase by 100 pixel, i should have horizontal scroll bar. but am not able to enable it. 

Could you let me know what is the property to be used in C# like:

  RadPivotGrid1.ClientSettings.Scrolling.AllowVerticalScroll = true;

 

Thanks,

Mohan Pal

Hi,

I'm using the following JS in my base page

            function RefreshDiscussionNotesGrid() {
                RefreshGrid("<%=rgDiscussionNotes.ClientID %>");
            }

            function RefreshGrid(ClientID) {
                $find(ClientID).get_masterTableView().rebind();
            }

I'm calling this from an iframe:

            function RefreshDiscussionNotesGrid() {
                jQuery(document).ready(function () {
                    $("input[id*='btnCloseModal']", parent.document).click();
                    window.parent.RefreshDiscussionNotesGrid();
                });
            }

I'm receiving an error in IE11:

Accessing the 'caller' property of a function or arguments object is not allowed in strict mode

Hello,
Is it possible to change the numeric index of the items in a RadGrid and perhaps update them in a similar fashion to the item que on NetFlix? basically changing the number in the index would move the item to that position in the grid.

Thanks

Hi there,

i want to update my DataSource of the RadGrid with the Rebind-Method in a Button_Click-Event. 
In the NeedDataSource i update the DataSource properly but the new DataSource is not shown in my Grid. It just don“t do any update.

Can you me help out here?

Here my Grid:

<telerik:RadGrid ID="radInvoiceOverview"
                                runat="server"
                                AutoGenerateColumns="true"
                                OnNeedDataSource="radInvoiceOverview_NeedDataSource"
                                GridLines="None"
                                Width="650px"
                                AllowPaging="true"
                                PageSize="100"
                                ShowHeader="true"
                                ItemStyle-Height="30px"
                                AlternatingItemStyle-Height="30px">
 
                   <ClientSettings AllowKeyboardNavigation="true"
                                   EnablePostBackOnRowClick="true"
                                   EnableRowHoverStyle="true">
 
                       <Selecting AllowRowSelect="true"/>
                   </ClientSettings>
 
                   <SortingSettings  EnableSkinSortStyles="false"/>
 
                   <PagerStyle  Mode="NumericPages"
                                AlwaysVisible="true"
                                PageButtonCount="10"
                                PagerTextFormat="{4} Page {0} from {1}, Transactions {2} to {3}"/>
 
                   
                   <MasterTableView EnableNoRecordsTemplate="true" AutoGenerateColumns="true">
                       <NoRecordsTemplate>
                           <div style="width:100%;text-align:center;margin-top:10px;margin-bottom:10px;"><b>some Text</b></div>
                       </NoRecordsTemplate>
                   </MasterTableView>
               </telerik:RadGrid>


And here my Events:
protected void btnShow_Click(object sender, EventArgs e)
        {
            radInvoiceOverview.Rebind();
        }
 
        protected void radInvoiceOverview_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
             
            try
            {
                radInvoiceOverView.DataSource = GetUnprintedInvoicesForClient(); //<-- brings a DataTable as Source
            }
            catch (Exception ex)
            {
                //do some logging
            }
        }
Do you know what i“m missing in this scenario?

regards
Luke

Hopefully someone can point me in the right direction.

 

I have a Grid that i populate from a list that i get from my backend. it works great like this. i do have paging that works, but sorting is one i am having trouble with.

 

I set the allowsort property to true, but the columns do not allow me to click on them to sort.

 

Any Suggestions?

Hi

I have a problem with one AJAX call blocking another.  I suspect that I don't really fully understand what's going on "under the hood/bonnet" to know if I can fix this behaviour so would appreciate a full explanation if one exists, or better still a way to fix the behaviour.

Scenario
I have a page that displays a list of products.  Most of the information for these products is quick to get from the database, but stock data requires calls to 3rd party systems.

The solution is to load the page quickly with the majority of the data.  As soon as the page has loaded, an AJAX call is automatically fired to retrieve stock information that takes between 5-10 seconds.

Meanwhile, the Shopper can click on a button that also does an AJAX call back - the call is very quick and the results are displayed in a Tooltip (think that fact is probably irrelevant).

The initial problem was that when the Shopper clicked on the button, it cancelled the call to get stock.  I got around that problem by setting the RequestQueueSize property to be a number greater than 0.

Problem
If the Shopper spends 10 seconds reading the page and then clicks on the button, they see their results load almost instantaneously - this is because the Stock data has been returned.  However, if the shopper clicks on the button as soon as they page has loaded, then they will have to wait until the long-running call to get the stock information has completed.

My understanding ...
I thought that the whole point of being asynchronous was that once the JavaScript engine had sent the Request off to the server, it would then be free to handle other jobs in the queue.  Once the Response was received from the Server, it would then be added to the queue.

This being the case, it should work as follows:
  1. Request for stock sent
  2. Request for button-click sent
  3. Response for button-click received (and processed)
  4. Response for stock received (and processed)

However, it appears that the second Request is not sent until the first Response has been received.
I thought that a "standard" browser could have a maximum of two connections to a single domain (HTTP Limits) so if nothing else is occuring on my page then this should work as expected.

So is Telerik RadAjaxPanel managing a single queue and only firing off a Request if the previous Request has already been returned?

If so, then from the link regarding HTTP connection limits, there really ought to be two queues per domain.

Think I need that explanation....

Many thanks in advance!

Hello, I am using GridClientSelectColumn, and I'm trying to add a javascript onclick event.  I added the following to my ItemDataBound grid event:

 

 

if (e.Item is GridDataItem)

 

{

 

 

GridDataItem item = (GridDataItem)e.Item;

 

 

 

CheckBox chkbx = (CheckBox)item["ClientSelectColumn"].Controls[0];

 

chkbx.AutoPostBack =

 

true;

 

chkbx.Attributes.Add(

 

"OnClick", "return alert('" + chkbx.Checked + "');");

 

}



But every time, the value is displayed as false after I check the box.  I just want to get the value of the checkbox after it is selected.

I have a RadWizard that I would like to have a "loading" function on, when user clicks on "Next" button. However, it only works on the first click. All subsequent clicks on "next" show no loading from the RadAjaxLoadingPanel.

    </telerik:RadGrid>

 

When a user wants to add a new row, he has to select a name ("Nombre") and a connection ("Conexion") from a window that pops up and assigns the selected connection to the selected cell. I can validate the name using the built-in validator for BoundColumns, however, I haven't found a way to validate the Eval("NombreConexion") that is on the ItemTemplate of the GridTemplateColumn so that it is not an empty value (some users forget to assign a connection).

Is there any way of doing this? I can't use a FieldValidator because the Eval field is not a control and if I try to transform it into a radlabel I just get errors.

Thank you.
