[Solved] Automatic column resize depending on content length
Hi, I would like to know if it is possible to resize a column depending the length on the content.

For example, I have a product that uses several dynamic fields with contents ranging from 1 character up to (think free-text).

Here's the code I use to generate all fields:

        DataTable createDataTableWithCustomFields() 
        { 
            NBKCustomer[] custs = c.GetCompetitors(AuthToken); 
            var theVeryLatestNote = custs.SelectMany(cu => cu.OwnerEntity.EntityNotes).OrderByDescending(n => n.Created).FirstOrDefault(); 
 
            var IamEskimoe = from cuss in custs 
                             select new 
                             { 
                                 cuss.CompetitorID, 
                                 cuss.companyName, 
                                 cuss.countryRegistrationNumber, 
                                 cuss.emailAdress, 
                                 cuss.homepageUrl, 
                                 cuss.headquarterOrBranch, 
                                 cuss.legalFormCode, 
                                 cuss.created, 
                                 cuss.updated, 
                                 cuss.branchesQuantity, 
                                 cuss.OwnerEntity, 
                                 Notes = cuss.OwnerEntity.EntityNotes.Count(), 
                                 HasTheLatestNote = (theVeryLatestNote != null ? (cuss.OwnerEntity.EntityID == theVeryLatestNote.OwnerEntity.EntityID) : false) 
                             }; 
 
            DataTable dt = new DataTable();

NeedDataSource Question
Hey all,

I have been very busy lately working on a new project that uses MVP. We are plugging along and everything was going very nicely until we got to our event viewer page in our admin menu. We are using a custom implementation of the standard .NET 2.0 web event schema that we built using the MVP pattern. I want to use a RadGrid for the main display because it is a nice package for our requirements (toggle, click to expand, etc). This brings me to the problem. With MVP, the user interface is extremely thin. We built the classes and code using TDD best practices, and unfortunately, we didn't do our homework on the RadGrid very well. We mistakenly counted the NeedDataSource event as a standard EventHandler (like most other event delegates that perform data binding). What could we do to resolve this problem? Keep in mind that the obvious solution (adding the Telerik.Web.UI reference to my presenter, and model projects) is absolutely out of the question.

View Interface
public interface IEventViewerView 
{ 
        event EventHandler StartUp; 
        event EventHandler NeedDataSource; 
        object DataSource { set; } 
        object OnNeedDataSource { set; } 
} 

Presenter Class
public class EventViewerPresenter 
{ 
        private readonly IEventViewerView _view; 
        private readonly IEventViewerRepository _repo; 
 
        public EventViewerPresenter(IEventViewerView view) : this(view, new EventViewerRepository()) 
        { 
 
        } 
 
        public EventViewerPresenter(IEventViewerView view, IEventViewerRepository repo) 
        { 
            if (view == null) 
                throw new ArgumentNullException("view may not be null"); 
            if (repo == null) 
                throw new ArgumentNullException("repo may not be null"); 
            _view = view; 
            _repo = repo; 
            _view.NeedDataSource += new EventHandler(_view_NeedDataSource); 
            _view.StartUp += new EventHandler(_view_StartUp); 
        } 
 
        void _view_NeedDataSource(object sender, EventArgs e) 
        { 
            _view.OnNeedDataSource = _repo.List(); 
        } 
 
        void _view_StartUp(object sender, EventArgs e) 
        { 
            _view.DataSource = _repo.List(); 
        } 
} 

Here is where things go sideways. I get the following error in the code below. Cannot implicitly convert type 'System.EventHandler' to 'Telerik.Web.UI.GridNeedDataSourceEventHandler'.
protected void Page_Load(object sender, EventArgs e) 
{ 
        _presenter = new EventViewerPresenter(this); 
        grdEvents.NeedDataSource += NeedDataSource; // Errors here... 
        if (StartUp != null) StartUp(this, EventArgs.Empty); 
} 
 
public event EventHandler StartUp; 
public event EventHandler NeedDataSource; 
 
public object DataSource 
{ 
        set  
        { 
            if (!IsPostBack) 
            { 
                grdEvents.DataSource = value; 
                grdEvents.DataBind(); 
            } 
        } 
} 
 
public object OnNeedDataSource 
{ 
        set { grdEvents.DataSource = value; } 
} 

I am having trouble figuring out how to solve this without breaking the rules for MVP.

I love these engineering challenges, but this one has me pretty well stumped.

Any Thoughts?

Thanks,

John

Potentially Dangerous Request in ASP.NET 4
Hi,

I am getting a popup with "Error 500: Potentially Dangerous Request" when trying to use RadSpell on multiple controls in ASP.NET 4. The error occurs the moment I click "Check Spell".

Reproduction: Create a fresh ASP.NET 4 project (VB) and add the HTTPRequestHandler for RadScriptManager and RadSpell to the web.config through Telerik's SmartTags. Then add the RadScriptManager and RadSpell to your Default.aspx, create two basic text inputs and try hook up both (i.e. ControlsToCheck="TextBox1,TextBox2")

Web.config (excerpt)
        <httpHandlers> 
            <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/> 
            <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/> 
            <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/> 
        </httpHandlers> 
        <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/></system.web> 
    <system.webServer> 
        <modules runAllManagedModulesForAllRequests="true"> 
        </modules> 
        <validation validateIntegratedModeConfiguration="false"/> 
        <handlers> 
            <add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler"/> 
            <add name="Telerik_Web_UI_SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler"/> 
            <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource"/> 
        </handlers> 
    </system.webServer> 


Default.aspx
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false" 
    CodeBehind="Default.aspx.vb" Inherits="RadSpellTest._Default" %> 
 
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
 
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> 
</asp:Content> 
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> 
    <h2> 
        Welcome to ASP.NET! 
    </h2> 
     
     <telerik:RadScriptManager ID="RadScriptManager1" runat="server" /> 
 
     <input type="text" id="TextBox1" /> 
 
     <input type="text" ID="TextBox2" /> 
 
     <telerik:RadSpell ID="RadSpell1" Runat="server" ControlsToCheck="TextBox1,TextBox2" IsClientID="True" SupportedLanguages="en-US,English" /> 
 
</asp:Content> 
 

Attached you can find a screenshot of the error message.

Note: It does work when TargetFramework of the project is set to 3.5 instead of 4.0 or if RadSpell is given only one ControlToCheck.

Thanks for any help,
Matt

get_masterTableView() error!

I have three radgrids on one aspx page.

If you click on a row in RadGrid1 it will update the results in Radgrid2, and if you click on a row in Radgrid2 it will update the results in Radgrid3. 

 

In RadGrid3 I have a GridTemplateColumn with an ImageButton that opens a new page using the RadWindowManager.  This works great and the window opens, but only for the first row in RadGrid3.  If I click on any other row I get the following JavaScript error.

 

Get_masterTableView(0.get_dataItems()[…] is null or not an object.

 

I have used the same code for other pages and it works flawlessly.  The only difference here is I am using multiple grids vs. one grid on the page. 

 

I think since RadGrid1 had only one row the RadWindowManager is pointing to it, I need the RadWindowManager to use the results from RadGrid3


Code for WindowManager and AjaxManager
 <telerik:RadWindowManager ID="RadWindowManager1" Style="z-index: 8000" Skin="Telerik"

                                     </telerik:RadGrid> 

My CS code is
 protected void RadCustomer_ItemCommand(object source, GridCommandEventArgs e)  
    {  
        RadGrid selGrid = (RadGrid)source;  
        if (e.Item is GridCommandItem)  
        {  
            //ExportPDF button clicks  
            if (e.CommandName == "lnkCustExport")  
            {  
                //Setting the PDF flag to true  
                isPdfExport = true;  
                ConfigureSelectFormsPDFExport(selGrid);  
                selGrid.MasterTableView.ExportToPdf();  
                e.Item.OwnerTableView.Rebind();  
            }  
        } 
So guide me to solve the issue

-Thanks

Export to Excel - exports dataset as well as grid
DataSet dsAdminEventInvites = new DataSet();  
EventInvite.GetEventInvites(databaseName, eventID, ref dsAdminEventInvites, ref errorMsg);  
rgInvitesExport.DataSource = dsAdminEventInvites;  
rgInvitesExport.DataBind();  
 
rgInvitesExport.ExportSettings.OpenInNewWindow = true;  
rgInvitesExport.ExportSettings.ExportOnlyData = true;  
rgInvitesExport.ExportSettings.IgnorePaging = true;  
rgInvitesExport.ExportSettings.FileName = "EventAttendees_Report";  
 
rgInvitesExport.MasterTableView.ExportToExcel(); 

That is my export code....   here is the grid:

<telerik:RadGrid ID="rgInvitesExport" runat="server" > 
            <MasterTableView> 
                <Columns> 
                    <telerik:GridBoundColumn DataField="EventID" HeaderText="Event ID" UniqueName="EventID" /> 
                    <telerik:GridBoundColumn DataField="InviteID" HeaderText="Invite ID" UniqueName="InviteID" /> 
                    <telerik:GridBoundColumn DataField="ProfessionalID" HeaderText="Professional ID" UniqueName="ProfessionalID" /> 
                    <telerik:GridBoundColumn DataField="Title" HeaderText="Title" UniqueName="Title" /> 
                    <telerik:GridBoundColumn DataField="Affiliation" HeaderText="Affiliation" UniqueName="Affiliation" /> 
                    <telerik:GridBoundColumn DataField="Degrees" HeaderText="Degrees" UniqueName="Degrees" /> 
                    <telerik:GridBoundColumn DataField="Specialty" HeaderText="Specialty" UniqueName="Specialty" /> 
                    <telerik:GridBoundColumn DataField="FirstName" HeaderText="First Name" UniqueName="FirstName" /> 
                    <telerik:GridBoundColumn DataField="MiddleName" HeaderText="Middle Name" UniqueName="MiddleName" /> 
                    <telerik:GridBoundColumn DataField="LastName" HeaderText="Last Name" UniqueName="LastName" /> 
                    <telerik:GridBoundColumn DataField="City" HeaderText="City" UniqueName="City" />

                    <telerik:GridBoundColumn DataField="CellPhone" HeaderText="CellPhone" UniqueName="CellPhone" /> 
                    <telerik:GridBoundColumn DataField="Fax" HeaderText="Fax" UniqueName="Fax" />

                    <telerik:GridBoundColumn DataField="DietaryNeedOther" HeaderText="Dietary Need Other" UniqueName="DietaryNeedOther" /> 
                    <telerik:GridBoundColumn DataField="BestContact" HeaderText="Best Contact" UniqueName="BestContact" /> 
                    <telerik:GridBoundColumn DataField="BestContactOther" HeaderText="Best Contact Other" UniqueName="BestContactOther" /> 
                    <telerik:GridBoundColumn DataField="ResponseDateTime" HeaderText="Registered Date and Time" UniqueName="ResponseDateTime" /> 
                    <telerik:GridBoundColumn DataField="Status" HeaderText="Status" UniqueName="Status" /> 
                </Columns>                          
            </MasterTableView> 
        </telerik:RadGrid>
