Insert item is available only when grid is in insert mode

I want to populate fields within a radgrid with some phony data when the button is clicked.
The GetInsertItem() statement causes exception:
Exception Details: Telerik.Web.UI.GridException: Insert item is available only when grid is in insert mode.

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<div>

<telerik:RadButton runat="server" ID="RadButton1" AutoPostBack="true" Text="fill data" ButtonType="LinkButton" onclick="RadButton1_Click"></telerik:RadButton>

</div>

<telerik:RadAjaxPanel runat=server>

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"

ShowStatusBar="True" GridLines="None" OnNeedDataSource="RadGrid1_NeedDataSource" OnUpdateCommand="RadGrid1_UpdateCommand"

OnInsertCommand="RadGrid1_InsertCommand" OnCreateColumnEditor="RadGrid1_CreateColumnEditor"

OnPreRender="RadGrid1_PreRender" OnItemDataBound="RadGrid1_ItemDataBound" OnItemCreated="RadGrid1_ItemCreated">

<MasterTableView DataKeyNames="id" CommandItemDisplay="Top">

<Columns>

<telerik:GridBoundColumn HeaderText="Emp" DataField="emp" UniqueName="emp">

protected void RadButton1_Click(object sender, EventArgs e)

{

GridEditFormInsertItem i = (GridEditFormInsertItem)RadGrid1.MasterTableView.GetInsertItem();

RadTextBox r = (RadTextBox)i.FindControl("emp");

r.Text = "Johnny";

}

How to bind a Grid on client side to JSON Data WITHOUT WebService or WebMethode?

I’m currently working in a SharePoint 2010 environment and need to bind a telerik ASP.Net AJAX Grid (latest version) to some JSON data that is created by an ASHX handler.

Prerequisites:

I need to use the JSON output from the ASHX handler and can’t build/deploy my own WCF Service
I need to wrap the Grid in a SharePoint 2010 WebPart (ascx) so I do not want to use WebMethods from an ASPX page

I have searched the forum and the web but was not able to find a sample that does not use a WebMethod or a WCF service. Can someone please point me in the right direction for this scenario?

Thanks in advance
Dirk

DropDownList Causing Full Postback Inside RadAjaxPanel

Good morning,

I've done my fair share of searching for the past hour and haven't been able to solve what seems to be a simple mind boggling issue.

Please find below the following simple front end code.

<Rad:RadAjaxPanel ID="RadAjaxPanel1" EnableAJAX="true" runat="server">
            <asp:DropDownList ID="ddlFirstDDL" AutoPostBack="true" OnSelectedIndexChanged="ddlFirstDDL_SelectedIndexChanged" runat="server" />

    </Rad:RadAjaxPanel>

Pretty basic, I know. When changing the index of the DDL, the page is performing a full postback. Swapping a different control in, like a CheckBoxList, works as expected with a partial postback.

What am I missing?

File Filter Doesn't Work

Hi,
I need to filter the files displayed in the browse dialogue window based on file types. I am using RadAsyncUpload control to
accomplish this.

When I browse in FF, I can see two browse button displayed. Clicking on first browse button doesn't open dialogue with file lists. Attached the image. I want a simple file upload control with single browse button. I had a similar issue in IE but resolved by adding the following. But issue still persists in FF.

<TeleControl:RadStyleSheetManager runat="server" ID="RadStyleSheetManager1"> </TeleControl:RadStyleSheetManager>
When I browse with applying file filter for Image files(jpg,png), It shows all files in the open dialogue window instead of showing only those files with extension .jpg or .png. Attached the screen shot. But when I refresh the page it works fine.
Can you please explain how does this file filter works in RadAsyncUpload w.r.t browsers. As far as I know, It depends on upload module. IE prefers silver light first where as FF prefers flash. Is that possible to make filters work in IE with having only flash (not silverlight)?. In which scenario does this combination (IE or FireFox with only flash) fails?.

Please find the aspx code:

<TeleControl:RadStyleSheetManager runat="server" ID="RadStyleSheetManager1"></TeleControl:RadStyleSheetManager

<TeleControl:RadAsyncUpload ID="RadAsyncUpload1" runat="server"

<Localization Select="Browse"

/>

</TeleControl:RadAsyncUpload>

C# (asp.net page behind):

protected void Page_Load(object sender, EventArgs e)

{

var filter = new FileFilter();

filter.Description = "GftxFiles(gftx,jpg)";

filter.Extensions = new string[2];

filter.Extensions[0] = "gftx";

filter.Extensions[1] = "jpg";

RadAsyncUpload1.FileFilters.Add(filter);

}

Drop Down issue on Mobile Browsers

Hi,

We've been testing cross platform compatibility of our website and have encountered an issue with the positioning of the drop downs on mobile (android & ios) browsers.

As the attached screenshots show; when the page is zoomed to fit the screen, the drop downs of the right hand items no longer expand in the correct place. It appears that they being positioned where the edge of the screen would be if the page was in an un-zoomed state.
Is there a work around to this issue?

If you would like more information please let me know.

Cheers,

Rob

Screenshot 1: Shows the last menu item (insurance) that expanded correctly
Screenshots 2 & 3: show the next menu items (Apply & About Us) that are incorrect

[Solved] Add New Record, but no Edit Column

Hi there,
I am new to RadGrid so please excuse.
I need to have users Add New Records or Remove records only. This is inline editing mode written in VB.

The issue I face is on click of the Add New Record from the CommandItem menu creates a new row, but does not allow a user to Submit or Cancel. If I enable the Edit Column, I see the red X for cancel and green Checkmark for submit.
However if I add the EditColumn to the grid, and click Add New Record these options are displayed.
How can I provide Add New without allowing enabling Edit of existing rows?

Thank you

Numeric Textbox Not Decorating Correctly

I have a web page that uses a Form Decorator in a master page. All is working fine, except for the Numeric Textbox. It is not accepting the RoundedCorners setting of the Form Decorator. A screen capture showing the page is attached.

The source code for the Decorator is:

<telerik:RadFormDecorator Skin="Office2010Silver" Enabled="true" ID="QsfFormDecorator" DecorationZoneID="rfd-demo-zone" runat="server" DecoratedControls="All" EnableRoundedCorners="true" EnableEmbeddedSkins="true" />

The source code for the numeric textbox (Line #) is:

<telerik:RadNumericTextBox ID="MPlanActLine" runat="server" TabIndex="1" Width="100px" Type="Number" NumberFormat-DecimalDigits="0"></telerik:RadNumericTextBox>

You will notice there is a second numeric textbox (N Days After Contract Signing) on the page. It also does not show rounded corners.

<telerik:RadNumericTextBox ID="MPlanActCPDaysAfterSigning" runat="server" TabIndex="4" Width="100px" Type="Number" NumberFormat-DecimalDigits="0"></telerik:RadNumericTextBox>

All other text boxes on the page are standard MS asp:TextBoxes. Also, you will see that the Rad ComboBox (Letter) has correctly displayed rounded corners.

Is there something I am doing incorrectly or is there a problem with the numeric textbox?

Thanks in advance for assistance!

Lynn
