Batch Editing doesnt work with ajax

Hey guys,

im trying to follow the example from http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx but i am unable to follow. I removed the datasource part becuase im not having the demo database installed and tried to use some static data instead but it seems like somehow neither my events nor the ajax stuff is fired. Anyone 

 

Codebehind: 

using System;

RadGrid Aggregation

Hi,  

We have a RadGrid control called "RadGrid1" and have it defined as follows in our ASPX page

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="Both">
</telerik:RadGrid> 

In our Vb.Net codebehind, we are using an aggregate function as follows to display the sum in the footer of the grid.

boundcol(index).Aggregate() = GridAggregateFunction.Sum

We do not want all the row items to be included in this sum.

Is there a way to only include the last 2 records in the summation?

I tried to configure RadGrid1_CustomAggregate using the follow code in the ASPX file

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="Both" Aggregate="Custom" OnCustomAggregate="RadGrid1_CustomAggregate">
</telerik:RadGrid> 

The vb.net file looks like the following for CustomAggregate configuration:

Protected Sub RadGrid1_CustomAggregate(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCustomAggregateEventArgs) Handles RadGrid1.CustomAggregate

End Sub

However, this event is not being fired.

I am using Telerik DevCraft version 2013.3 1014

Please advise how we can only include the last 2 records in the summation.

Thanks!

Display Server Error Page with Aajaxified Controls
I have a page with lots of different inputs that I'm using RadAjaxManager to Ajaxify. The problem is that if there is an error, it is thrown like a Script error and users are not noticing an issue and not reporting it to be fixed. I would like to throw a standard ASP.Net Server Error screen but can't seem to figure out how to accomplish or find an answer. Any help is appreciated.

RadGrid delete\update child grid

For grid  - update\delete\insert hierarchy I am not able edit\update child grid. I am able to edit\update parent grid but not the child grid though both are using the same code behind. I checked with the sql queries too. For child grid, when I click on edit button, it enables editing but when I click on update after changing the values, it is not updating in UI nor in database table. It is not giving any error though. Below is my code behind. Please if anybody can help me!

String format issue in RadGrid

Hi Team,

 While i'm trying to bind the string data to the Rad Grid it is not binding exact value which i have pulled from Data Base.

For Example i'm pulling the Data    : -   "A     BC         E F G"      and binding the same data to the Rad Grid, the problem here is the rad grid column is trimming out all the spaces and displaying like     :-  "A BC EFG"    

Here i need to bind the exact data which i'm pulling from Database.

Could you please help me out from this issue.

 

Thanks in Advance

A.Shrujan

RadListView Linq and Cache

I am trying to keep the latency to a minimum when using a Radlistview which grabs it's data from sql with linq. Example of how data is currently retrieved is as follows:-

<telerik:RadDropDownList ID="RadDropDownListSort" runat="server" Skin="MetroTouch" CssClass="sortCtrl" DefaultMessage="Sort by..." Width="175px" AutoPostBack="False" OnClientItemSelecting="sortSelecting" >
            <Items>
                <telerik:DropDownListItem Text="Sort by Price" Value="SalePrice" />
                   <telerik:DropDownListItem Text="Sort by Year" Value="YearOfMan" />
                <telerik:DropDownListItem Text="Sort by Location" Value="Location" />
                <telerik:DropDownListItem Text="Sort by Make/Model" Value="Make" />
                <telerik:DropDownListItem Text="Sort by Category" Value="Category" />
            </Items>
        </telerik:RadDropDownList>

<telerik:RadListView ID="RadListView1" runat="server" DataKeyNames="ListingID,GstOptionID" ItemPlaceholderID="ListingsContainer"
       AllowPaging="True"   PageSize="10" AllowMultiFieldSorting="True" CanRetrieveAllData="True">
                  <LayoutTemplate>
                        <asp:Panel ID="ListingsContainer" runat="server" />
                   <table class="pagerTable pagertiles">
               <tr>
                   <td>
                       <telerik:RadDataPager ID="RadDataPager1" runat="server" PagedControlID="RadListView1"
                           PageSize="10" Skin="MetroTouch" CssClass="dataPager" >
                           <Fields>
                               <telerik:RadDataPagerButtonField FieldType="FirstPrev" />
                               <telerik:RadDataPagerButtonField FieldType="Numeric" />
                               <telerik:RadDataPagerButtonField FieldType="NextLast" />
                               <telerik:RadDataPagerPageSizeField PageSizeText="Tiles per page: " PageSizeComboWidth="62" PageSizes="20 30" />
                               <telerik:RadDataPagerGoToPageField CurrentPageText="Page: " TotalPageText="of" SubmitButtonText="Go"
                                   TextBoxWidth="20" />
                               <telerik:RadDataPagerTemplatePageField>
                                   <PagerTemplate>
                                       <div style="float: right">
                                           <b>Items
                                                       <asp:Label runat="server" ID="CurrentPageLabel" Text="<%# Container.Owner.StartRowIndex+1%>" />
                                               to
                                                       <asp:Label runat="server" ID="TotalPagesLabel" Text="<%# IIF(Container.Owner.TotalRowCount > (Container.Owner.StartRowIndex+Container.Owner.PageSize), Container.Owner.StartRowIndex+Container.Owner.PageSize, Container.Owner.TotalRowCount) %>" />
                                               of
                                                       <asp:Label runat="server" ID="TotalItemsLabel" Text="<%# Container.Owner.TotalRowCount%>" />
                                               <br />
                                           </b>
                                       </div>
                                   </PagerTemplate>
                               </telerik:RadDataPagerTemplatePageField>
                           </Fields>
                       </telerik:RadDataPager>
                   </td>
               </tr>
                          </table>
       </LayoutTemplate>
       <ItemTemplate>
        ....
       </ItemTemplate>
        
       <EmptyDataTemplate>
      ...
       </EmptyDataTemplate>
   </telerik:RadListView>

 

Private Sub RadListView1_NeedDataSource(sender As Object, e As Telerik.Web.UI.RadListViewNeedDataSourceEventArgs) Handles RadListView1.NeedDataSource
    Dim dsTiles As IQueryable(Of ListingResults) = GetLinqListingData
    RadListView1.DataSource = dsTiles
End Sub

Having looked through the documentation and demos for the RadListview, I'm struggling to understand what amount of data is retrieved from sql and/or the server when the page first loads and on subsequent page change or sort on ajax call back.  When using Iqueryable does the Radlistview grab only the data for the page shown to the user?  IE 10 rows for page size of 10 retrieved from sql OR perhaps: All rows retrieved to server, but only 10 rows sent to client (user).

Presuming that it only grabs the rows for displayed items on the page, if I try to implement the usage of a shared (and/or local) cache as follows, the full set of rows would need to be retrieved from sql for first save to the cache. And on each and every page change or sort, the full set of rows is again retrieved from the cache.  A suggested example of using cache:

Private Sub RadListView1_NeedDataSource(sender As Object, e As Telerik.Web.UI.RadListViewNeedDataSourceEventArgs) Handles RadListView1.NeedDataSource
    Dim dsTiles As List(Of ListingResults) = GetCacheData
    If dsTiles is nothing
        dsTiles = GetLinqListingData
        SaveCacheData(dsTiles)
    End If
    RadListView1.DataSource = dsTiles
End Sub

 

Would greatly appreciate any explanation on how data is retrieved and any suggestion of whether cache is beneficial for short-term single user usage and longer term subsequent visitors seeking the same data.

Thank you

telerik dll conflict for SharePoint 2013

We have a commercial SharePoint 2013 web part application for which we license the Telerik.Web.UI dll, etc.

We build the dlls with our own .snk file (e.g. unique PublicKeyToken) and custom initialization (so noone else can use the dlls).

The dlls are installed in the GAC

At a customer site, they have our web part app and that of another company who also installs their version of the Telerik.Web.UI dlls, etc.

Problem - either one app or the other will work, but not both.

While it is possible to specify a specific version of the dll (including PublicKeyToken) in the SharePoint web.config file, there can only be one web.config file for all web part apps (for that SP site collection) and in that web.config only qualifiedEntry element for the dll with the name Telerik.Web.UI.

How to resolve (dynamic load of the specific dll?, build a "private" version of the Telerik dlls, rename the dll file/assembly name? Some other magic we don't know about?)
