Open RadBinaryImage from Radgrid as a Popup

Hi,

I refer to this demo: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandradasyncupload/defaultcs.aspx?product=grid

I have tried so many times but i just can't seem to get this done. What I am trying to accomplish, if i use this exact demo, is that when i click on the image in that "Image" column it must popup in a window that contains the image that i clicked on but just in a larger scale so that it can be viewed better. So basically just a quick view of the selected image.

Could someone please help me on this?

Regards,
Anel

Mobile Browsers Causing Menu to Close, Controls in Template Inaccessible

Hi, I'm working with a radmenu that has only one root item. The behavior I want is for a user to be able to click on the menu item, get a dropdown with login controls, and use those to log into the site I'm working on. I already set ClickToOpen="true", and I'm using a ContentTemplate for the textboxes, button, and so forth. I've tested my setup in Chrome, IE, and Safari on desktop browsers, and it works exactly the way I want. The problem occurs on mobile browsers (tested on Safari and Chrome for iOS 8, and Chrome for Android). When I go to my site on a smartphone, for example, and tap on a textbox to start entering login credentials, the whole menu closes. When I tested in Chrome on iOS 8, I noticed that the onscreen keys would pop up for a split second, and then go away along with the menu. This makes it impossible to use the login controls on a mobile device.

The client I'm working with insists that the site be mobile-friendly, so I need to figure this out, and would like to be able to use the radmenu control, though I'm open to other options that will achieve the functionality I need.

Here's my markup for the controls (sorry the formatting isn't great):

01.<div class="login-box">

02. <telerik:RadMenu ID="rm1" runat="server" CssClass="RadMenu" ClickToOpen="true" OnClientItemOpened="ExternalitemOpened" RenderMode="Classic">

03. <Items>

04. <telerik:RadMenuItem runat="server" PostBack="false">

05. <ContentTemplate>

06. <div id="loginDropDown">

07. <h2>Log In </h2>

08. <span class="failureNotification">

09. <asp:Literal ID="FailureText" runat="server"></asp:Literal>

10. </span>

11. <asp:ValidationSummary ID="vdsumLogin" runat="server" CssClass="failureNotification" ValidationGroup="vdgrpLogin" />

12. <div>

13. <fieldset>

14. <legend>Account Information</legend>

15. <p>

16. <asp:Label ID="lblUsername" runat="server" AssociatedControlID="txtUserN">Username:</asp:Label>

17. <asp:TextBox ID="txtUserN" runat="server" CssClass="textEntry"></asp:TextBox>

18. <asp:RequiredFieldValidator ID="rfvUserName" runat="server" ControlToValidate="txtUserN" CssClass="failureNotification" ErrorMessage="Please enter a username" ToolTip="Required field" ValidationGroup="vdgrpLogin">* Required</asp:RequiredFieldValidator>

19. </p>

20. <p>

21. <asp:Label ID="lblPassword" runat="server" AssociatedControlID="txtPassword">Password:</asp:Label>

22. <asp:TextBox ID="txtPassword" runat="server" CssClass="passwordEntry" TextMode="Password"></asp:TextBox>

23. <asp:RequiredFieldValidator ID="rfvPassword" runat="server" ControlToValidate="txtPassword" CssClass="failureNotification" ErrorMessage="Please enter a password" ToolTip="Required field" ValidationGroup="vdgrpLogin">* Required</asp:RequiredFieldValidator>

24. </p>

25. </fieldset>

26. <p class="submitButton">

27. <asp:Button ID="btnLogin" runat="server" CommandName="Login" Text="Log In" ValidationGroup="vdgrpLogin" CssClass="normalButton" OnClick="btnLogin_Click" />

28. </p>

29. </div>

30. <a href="../Register">register</a><br />

31. <a href="../Account/ForgotPassword.aspx">forgot password?</a><br />

32. <a href="../Account/RetrieveUsername.aspx">forgot username?</a>

33. </div>

34. </ContentTemplate>

35. </telerik:RadMenuItem>

36. </Items>

37. </telerik:RadMenu>

38.</div>

Here's the script I'm using:

function ExternalitemOpened(s, e) {

if ($telerik.isIE8) {

// Fix an IE 8 bug that causes the list bullets to disappear (standards mode only)

$telerik.$("li", e.get_item().get_element())

.each(function () { this.style.cssText = this.style.cssText; });

}

I'm also setting the text of the root item from code-behind. It tells the user they can click the menu to login or logout, depending on context. If they're currently logged in, then clicking the menu will fire an event handler that will log them out. Selections from that code:

rm1.Items(0).Text = "(logout)"

AddHandler rm1.ItemClick, AddressOf rm1_ItemClick1

rm1.Items(0).Text = "(committee login)"

Protected Sub rm1_ItemClick1(sender As Object, e As Telerik.Web.UI.RadMenuEventArgs)

Response.Redirect("~/Account/Logout.aspx")

End Sub

Also, the CSS from the markup:

.login-box{

width:1024px;

height:50px;

margin:0 auto;

margin-top:8px;

margin-bottom: 8px;

padding:0;

font-size: large;

}

.normalButton:disabled

{

border-radius: 30px;

background-color: #969696;

width: 150px;

height: 30px;

font-family: Arial, Helvetica, sans-serif;

font-style: italic;

font-size: large;

}

And the mobile CSS (where applicable):

@media only screen and (max-width: 768px) {

.login-box{

width:100%;

height:50px;

margin:0 auto;

margin-top:8px;

margin-bottom: 8px;

padding:0;

background-color:#E6E6E6;

text-align:left;

}

.login-box h1{

font-size:1em;

font-weight:normal;

letter-spacing:1px;

margin:0px 0px 0px 10px;

text-align:left;

padding-top:15px;

}

.normalButton

{

color: #FFFFFF;

border-radius: 30px;

background-color: #579767;

border: 2px solid #000000;

width: 150px;

height: 30px;

font-family: Arial, Helvetica, sans-serif;

font-size:medium;

}

.normalButton:disabled

{

color: #686868;

border-radius: 30px;

background-color: #969696;

border: 2px solid #D1D1D1;

width: 150px;

height: 30px;

font-family: Arial, Helvetica, sans-serif;

font-style: italic;

font-size:medium;

}

I have spent several hours playing with the markup and searching online for other instances of this issue, with no fix. I looked into using RenderMode="auto" or RenderMode="mobile", but neither worked the way I needed. I am using version 2015.2.623.40 of the web controls.

Please help me get this working on mobile browsers.

Radcombox checkbox Item selection in foreach loop not working when I use the OnItemsRequested event

Hello,

I use the OnItemsRequested event to get the data from database:

Below are design code:

                                            </telerik:RadComboBox>

And i use the following code in c#:

protected void ddlItem_OnItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
{

//write login code to get the data from database through ItemRequest event.

}

What I want is I use the checkbox to select multiple items or data from drop down and add all the checkboxs true to grid but when i use foreach loop then I can't get the checkbox true items.

Here is the code:

foreach (RadComboBoxItem ComboItem in ddlItem.CheckedItems)
        {
            if (ComboItem.Checked == true)
            {
            }
}

The above loop is not working when i try to get the checked true items.

Please help me as soon as possible.

I hope you understand my query.

Thanks

Bind Multi-column combobox to WebMethod

multi-column RadComboBox via a web method.

ASPX

<telerik:RadComboBox runat="server" ID="RadComboBox1" Width="200px"

        MarkFirstMatch="true"

        EnableLoadOnDemand="true"

        HighlightTemplatedItems="true"

        DroDownCssClass="exampleRadComboBox">

       <HeaderTemplate>

            <tr>

                <th class="col1">Category Name</th>

             <%--   <th class="col2">Some other column</th>--%>

            </tr>

        </ItemTemplate>

          <WebServiceSettings Method="GetCat" Path="Default.aspx" />

</telerik:RadComboBox>

Code Behind

[WebMethod]

       public static RadComboBoxData GetCatType(RadComboBoxContext context)

       {

           var x =

               "[{'CoachingSessionActivityCategoryID':0,'CoachingSessionActivityTypeID':1000005,'Category_Name':'Skills Conditioning','TeamID':0,'ClubID':1,'Type_Name':'Skills Con - Small Sided Games (Attack)'}]";

           var data = JsonConvert.DeserializeObject<DataTable>(x);

           RadComboBoxData comboData = new RadComboBoxData();

           var itemOffset = context.NumberOfItems;

           var endOffset = Math.Min(itemOffset + 10, data.Rows.Count);

           comboData.EndOfItems = endOffset == data.Rows.Count;

           List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(endOffset - itemOffset);

           for (int i = itemOffset; i < endOffset; i++)

           {

               RadComboBoxItemData itemData = new RadComboBoxItemData();

               itemData.Text = data.Rows[i]["Category_Name"].ToString();

               itemData.Value = data.Rows[i]["Category_Name"].ToString();

               result.Add(itemData);

           }

           comboData.Items = result.ToArray();

           return comboData;

       }

The question is:

1) How do I bind the combobox to the web method?

2) How do I bind multiple columns to the combo box with the web method?

iPod Style Combobox with Filter

Hi,

We're working on an application which has a RadComboBox multiple tiers which can be clicked through.

Similar to https://www.filamentgroup.com/examples/menus/ipod.html#

Menu 1

Food

Drinks

-> Click Food

Menu 2 appears

Starters

Main

Dessert

-> Click Dessert

Menu 3 appears

Ice Cream
Meringue with Orange

All within the same ComboBox?

Is it possible in UI for ASP.NET AJAX to achieve a similar result out of the box?

Additionally one of the requirements is the ability to filter the items based on the path.

So if the user types "Orange" it will bring back results of Meringue with Orange from Food > Dessert menu and Orange Juice from Drinks > Squash menu?

I hope that I've made sense.

Dynamically adding RadButtons

I am trying to dynamically add RadButtons to a page by simply sticking the HTML in on the page load. The buttons are not showing up on the page. I have tried using AddControl which does display the buttons, but after I call AddControl, I can no longer modify the InnerHtml. Any ideas how I can make this work? See Code below.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsCallback)
            return;

        CompSubMenuDiv.InnerHtml = "";

        int ItemNum = 0;
        AddMenuHTML("Item Title 1",
                    "Item Description 1",
                    "~\\Comparison.aspx", "~\\Comparison.aspx", "~\\Comparison.aspx",
                    ItemNum);

        AddMenuHTML("Item Title 2",
                    "Item Description 2.",
                    "~\\Comparison.aspx", "~\\Comparison.aspx", "~\\Comparison.aspx",
                    ItemNum);

    }

    protected void AddMenuHTML(string ModTitle, string ModDesc,
                               string LearnMoreURL, string SampleURL, string CreateIllURL,
                               int ItemNum)
    {
        // Add the html for one menu item.

Server-side column selected event

Hi,

I have a grid where the user will click a column and I want to handle that column-click server-side. I tried handling OnSelectedCellChanged (with EnablePostBackOnRowClick="true") but that only works when clicking cells, not columns headers. How can I achieve this?

Export to PDF performance issues

Hello,

We are using Telerik Grid control and having performance issues with the PDF export.
The details:

Grid control is used in a webpart under SharePoint 2013
Datasource is a SQL table, but accessing via ORM (LLBLGen Pro framework)
It is a Master-Detail view (details are closed by default and not exported to PDF) - source code attached below
It takes 60 seconds to generate a PDF from ~7000rows (it will be a ~24Mb PDF file, ~700pages)

I did some profiling from the C# webpart side and from the DB side too.
As you can see in the attachments there is only one SQL query which takes less than a second (381ms) to get the data.

1.EventClass StartTime EndTime Duration (ms) TextData Reads Writes RowCounts

2.Trace Start 2015-07-14 15:15:33.577

3.SQL:BatchCompleted 2015-07-14 15:15:33.577 2015-07-14 15:15:33.957 381 SELECT xx 1023 0 7632

4.Trace Stop 2015-07-14 15:15:33.957

But the other attachment is about the hot path in the code and it clearly shows that the Grid's internal methods are working hard for 60 seconds (!) to produce the PDF.

Telerik.Web.UI.RadAjaxControl.RenderPageInAjaxMode
Telerik.Web.UI.Grid.Export.TableViewExporter.PrepareForExportInternal

These two methods are running 98% percent of the time.

I've created an excel file with MS Excel 2010 on my local machine with the same data and saved it as a PDF. It took less then 10 seconds to generate and save the file.

Is it possible to increase the export's performance and decrease the necessary time to ~15 seconds?
What can cause this long rendering time? Maybe the master-detail view?

Thanks for your tips in advance!
