RadTextBox and Enter key will not fire DefaultButton

I have noticed since upgrading my Telerik.Web.UI to 2012.1.215.40 I have not been able to hit enter from a RadTextBox to fire the default button. I have tested it on many pages in my project, and every page is "broken".

I have made a test page, and the problem occurs with the RadTextbox with or without being wrapped in a RadAjaxPanel.

EDIT: RadMaskedTextBox and RadNumericTextBox work properly with the enter key. RadDatePicker, RadTimePicker, RadComboBox do not fire the submit button.

Any idea on how to fix this issue?

Here is my sample page:

<%@ Page Language="C#" AutoEventWireup="true" %>

<script runat="server">

protected void Page_Load(object sender, EventArgs e)

{

for (int i = 0; i < 10; i++)

{

rcb1.Items.Add(new RadComboBoxItem(i.ToString(), i.ToString()));

}

protected void btnSubmit_Click(object sender, EventArgs e)

{

ltlMessage.Text = DateTime.Now.ToString() + " - Postback Fired.";

}

</script>

Help with modifying hierarchical declaritive columns in code behind.

Greetings Telerik Community,

I am currently and successfully using the code block below to turn an edit column into a delete column. I do this because my customer wants in-line add and delete but no edit. My issue now is I need to do this for a column that is nested 1 level deep in a hierarchical grid. The column name is "EditColumn2". The problem is this column doesn't appear to exist when the PreRender is called and throws an exception. My guess is it is created on the fly when the expand arrow is clicked. Which event can I use to add a similar code block to so I can apply the same logic to turn an editboundcolumn into a delete column for the nested table?

protected void GridPreRender(object sender, EventArgs e)

{

foreach (GridDataItem item in MaintGrid.MasterTableView.Items)

{

ImageButton btn = (ImageButton)item["EditColumn"].Controls[0];

btn.CommandName = "Delete";

btn.ToolTip = "Delete";

btn.ImageUrl = "~/Stylesheets/Images/Delete3.gif";

btn.OnClientClick = "javascript:if(!confirm('Are you sure you wish to delete this record?')){return false;}";

}

How to sort by arithmetic result of several fields in client-side grid?

Hello,

I am using client-side binding grid, so all my columns are gridtemplatecolumn type and filled from web-service.
One of the columns is a result of some calculation.

<telerik:GridTemplateColumn HeaderStyle-CssClass='GridHeaderGreen ra' ItemStyle-CssClass='ra'

HeaderText="Start day throughput" SortExpression="START_DAY_DATA.IO_PER_SECOND">

<itemtemplate>

<asp:Label ID="StartPerSecond" runat="server" />

</itemtemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderStyle-CssClass='GridHeaderGreen ra' ItemStyle-CssClass='ra'

HeaderText="End day throughput" SortExpression="END_DAY_DATA.IO_PER_SECOND">

<itemtemplate>

<asp:Label ID="EndPerSecond" runat="server" />

</itemtemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderStyle-CssClass='GridHeaderGreen ra' ItemStyle-CssClass='ra'

HeaderText="Throughput growth">

<itemtemplate>

<asp:Label ID="PerSecondDelta" runat="server" />

</itemtemplate>

</telerik:GridTemplateColumn>

When I put SortExpression="(END_DAY_DATA.IO_PER_SECOND - START_DAY_DATA.IO_PER_SECOND)" into third column - I am getting the exception when trying to sort by this column.

I can't believe I can't solve this problem in a more elegant way than writing something like:
SELECT
END_DAY_DATA.IO_PER_SECOND,
START_DAY_DATA.IO_PER_SECOND
END_DAY_DATA.IO_PER_SECOND - START_DAY_DATA.IO_PER_SECOND
........
and putting SortExpression="3" for third column! :(

UPDATE: Lack of time for experiments: so, I've used the last approach: SortExpression="3" :)

RadComboBox Functionality

We have telerik license of version 2009.3.1314.35.

At one page, we have used radcombobox with ondemand rendering as below,

<telerik:RadComboBox ID="ddlEmployee" runat="server" Width="250px" Height="100px"
EmptyMessage="Select employee " EnableLoadOnDemand="True" EnableVirtualScrolling="true"
OnItemsRequested="RadComboBox1_ItemsRequested" DataTextField="Name" DataValueField="EmpNo"
Skin="WindowsXP" OffsetX="2" AllowCustomText="True" EnableEmbeddedSkins="False"
EnableAjaxSkinRendering="False" EnableEmbeddedBaseStylesheet="False" EnableItemCaching="True"
ShowMoreResultsBox="True">
</telerik:RadComboBox>

My requirement is to enable on demand functionality for employee list. The objective is, at page load I should be able to set selectedvalue item to employee combbox and also to achieve on demand functionality in it

The above scenario works fine if I dont set selectedvalue item to combobox in page load.

My observation while debugging.
The problem with RadCombobox is that if we bind the RadCombobox on page load, and try to click in combobox text area RadComboBox1_ItemsRequested is not get fired. However, if start writing something in RadCombobox text area RadComboBox1_ItemsRequested is get fired.

Please help us to achieve this functionality in combobox.

Thanks in advance.

Postback on mouse drag selection

I need to perform a postback on drag selection. I currently use

OnMouseUp="GridMouseUp(this, event)" on the RadGrid element to call

function GridMouseUp(sender, e) {

setTimeout(function () {

var grid = $find(window.gridId);

if (grid != null && grid.get_masterTableView().get_selectedItems().length > 0) {

__doPostBack(window.gridUniqueId);

}

}, 0);

}

This works for the drag select case but also does postbacks when clicking on the filter textboxes which I do not want. Is there any way in client code to detect OnMouseUp of a Drag select action?

AJAX Grid and Back Button

We want to use all the great AJAX features on the grid for sorting, paging, grouping, etc. Let's assume a user opens a page in our application with an AJAX-enabled grid and sorts on several columns and pages within the dataset several pages. Now the user double clicks a record which results in a navigation to a different page for more detail. Now, the user wants to go back to the grid so they click the Back button in the browser. I want to make sure my user returns back to page 2 with the appropriate sorting criteria applied. Does the Telerik grid place entries in the browser history that record the sequence of events (sorting and paging) prior to drilling down to the different page? Is this sort of functionality built-in to the grid so we don't have to worry about maintaining some session state on the server?

[Solved] Tournament knockout layout

Hello,

I'm trying to use the OrgChart for a tournament table layout. This means that you go from many items to fewer items. I know it is (for now) not yet supported to set the orientation from left to right but i can work around this and use top to bottom. To allow 2 items to melt into 1, i use grouping. This only works for one level though. as soon as the top level is halved, i need the second level to group 2 items together.
So i go from 8 items to 4items to 2 items to 1. This is in my opinion not possible with the current OrgChart.

multiple parents would be a great feature and would solve my problem.

Do you have any idea on when this feature might be introduced? Or do you have a workaround using another control or multiple groupings?

Thank you,

Phill
