I enabled the ShowButton property to the radtextbox, but while writing and the words reach the button I can't see the final of the text. 

<telerik:RadTextBox ID="RadTextBox1" runat="server" ShowButton="true"></telerik:RadTextBox>

If I disable the ShowButton and write something in the radtextbox, I can see the final words. 

How I can fix this?

The code in the ASPx file is 

 <DataCellStyle CssClass="cfDataCell" Width="9%"/>

The expected output in the client browser is

 <tr style="height: 35px;">
        <td class="rpgDataCell cfDataCell" style="width:9%;">823</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">2,488</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">7,518</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">10,851</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">13,017</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">13,069</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">13,253</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">12,799</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">9,861</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">4,543</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">2,038</td>
        <td class="rpgDataCell cfDataCell" style="width:9%;">592</td>

However the generated Html is as below:

 <tr style="height: 35px;">
        <td class="rpgDataCell" style="width:9%;">823</td>
        <td class="rpgDataCell" style="width:9%;">2,488</td>

We are using the Telerik tabStrip ASP.NET AJAX control.

We have set PerTabScrolling="true" on the tabStrip.

Then we have hidden a tab on the client side that is apart of the tabstrip.

Now when we scroll to the end of the list we receive a JavaScript error: Sys.InvalidOperationException: Cannot serialize non finite numbers.

This only happens when we hide a tab.

In Classic RenderMode, Windows7 skin, TreeView nodes are higher when inside ContentTemplate of RadPanelBarItem:

In the RadEditor we have the NewLineMode set to Div
We are also using a ToolsFile xml document to control the tools available in RadEditor.
The problem is the InsertParagraph tool now inserts <div> tags instead of <p> tags.
We want to keep the NewLineMode behavior as DIV while still having a tool that can insert a paragraph (i.e. a <p> tag).

To replicate this problem:

On the RadEditor demo page, first set "NEW LINES AS" to "Divs".
Then, in the editor content area just above the "Destinations" table, Type in three lines:

If you then toggle to the HTML tab, you will see that the Comment1 line is (incorrectly) bracketed by a <p> tag while the Comment2 and Comment3 lines are (correctly) bracketed by <div> tags.

Next, go back to the Design tab and position yourself at the beginning of the Comment3 line then click the [Insert Paragraph] button.

In the newly inserted "paragraph" type "Comment2b".

If you then toggle to the HTML tab you will see that Comment2b is incorrectly bracketed by a <div> tag.  It should be a <p> tag.

Currently the property LargeChange of RadSlider controls the following behaviors:

 - The interval for displaying value numbers in a slider with ticks;

 - The interval for moving the drag handle when an item in the slider is clicked. For example when LargeChange is set to 10, the currently selected value is 30 and the item with value 50 is clicked, the drag handle will be moved to 40;

Separating these functionalities will allow directly moving the drag handle to a clicked value on the slider track and displaying value numbers in the slider at the same time.

For the time being the DateTime object can be set to the AxisCrossingPoint on the client. For example:


			function OnLoadHandler(sender, args) {
				var kendoChart = sender.get_kendoWidget();
				var opts = kendoChart.options;
				opts.categoryAxis.axisCrossingValues = [0, new Date("2014, 11, 05, 19:15:00")];
		<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="600px" Height="400px">
			<ClientEvents OnLoad="OnLoadHandler" />
					<telerik:LineSeries Name="Product 1" DataFieldY="SellQuantity">
				<XAxis DataLabelsField="SellDate" BaseUnit="Minutes">
					<LabelsAppearance Step="15"></LabelsAppearance>
					<MinorGridLines Visible="false" />
						<telerik:AxisCrossingPoint Value="10" />
			<ChartTitle Text="LineSeries"></ChartTitle>

	protected void Page_Load(object sender, EventArgs e)
		if (!Page.IsPostBack)
			RadHtmlChart1.DataSource = GetData();

	protected DataTable GetData()
		DataTable dt = new DataTable();

		dt.Columns.Add("ID", typeof(int));
		dt.Columns.Add("SellQuantity", typeof(int));
		dt.Columns.Add("SellDate", typeof(DateTime));

		dt.Rows.Add(1, 2, new DateTime(2014, 11, 05, 18, 22, 22));
		dt.Rows.Add(2, 5, new DateTime(2014, 11, 05, 18, 56, 22));
		dt.Rows.Add(3, 6, new DateTime(2014, 11, 05, 19, 14, 22));
		dt.Rows.Add(4, 4, new DateTime(2014, 11, 05, 19, 48, 22));
		dt.Rows.Add(5, 7, new DateTime(2014, 11, 05, 20, 12, 22));

		return dt;

Currently, to make the MultiColumnComboBox control work in an EditTemplate of a Grid in Batch EditMode, custom implementation is needed as explained in Batch Editing Working With Templates and demonstrated here: Show short date, edit full date with batch editing

I have a few instances where I need OnClientSelectedIndexChanging inorder to stop the listbox selectedIndexChanged event from posting back in certain cases. In those cases I stop it from posting back by setting the e.set_cancel(true);

function CheckForListBoxReorder_OnClientEvent(sender, e) {
    if (ListboxReordered()) {
        alert('Please save changes to the bus order.');

This works very nicely, but I'm getting many errors because although it looks like it's still selected to the proper row in the listbox the selectedIndex is now -1.

Using CommandItemTemplate (Grid - Command Item) for Editing DetailTable records and selecting an item after filtering or from another page, one item from the first page is put for editing instead. Open the attached GIF animation (EditSelectedEditWrongItem.gif) to see it in action.


Currently the workaround we offer is to handle the EditSelected command manually for all the DetailTables Except for the Master.


Grid markup:


        <telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" Width="100%" PageSize="3"
            <MasterTableView Name="MasterTable" AutoGenerateColumns="true" DataKeyNames="OrderID">
                    <telerik:GridTableView Name="ChildTable" DataKeyNames="OrderID" AutoGenerateColumns="true" CommandItemDisplay="Top">
                            <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected" CssClass="btn btn-default">Edit Selected</asp:LinkButton>
                <Selecting AllowRowSelect="true" />


C# - ItemCommand


    protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
        // Logic applies for all the tables (detail tables) which are not named "MasterTable"
        if(e.Item.OwnerTableView.Name != "MasterTable" && e.CommandName == RadGrid.EditSelectedCommandName)
            e.Canceled = true;

            GridTableView detailTable = e.Item.OwnerTableView;

            if (detailTable.OwnerGrid.SelectedIndexes.Count == 0)

            foreach (GridDataItem selectedItem in detailTable.OwnerGrid.SelectedItems)
                selectedItem.Edit = true;



VB - ItemCommand

Protected Sub RadGrid1_ItemCommand(ByVal sender As Object, ByVal e As GridCommandEventArgs)
    If e.Item.OwnerTableView.Name <> "MasterTable" AndAlso e.CommandName = RadGrid.EditSelectedCommandName Then
        e.Canceled = True
        Dim detailTable As GridTableView = e.Item.OwnerTableView

        If detailTable.OwnerGrid.SelectedIndexes.Count = 0 Then
        End If

        For Each selectedItem As GridDataItem In detailTable.OwnerGrid.SelectedItems
            selectedItem.Edit = True

    End If
End Sub

ImageEditor keeps in the undo stack a reference to the last written text, but not last inserted one. 

Video: https://www.screencast.com/t/z6z5gwA6

Steps to reproduce:

1. Open https://demos.telerik.com/aspnet-ajax/imageeditor/examples/overview/defaultcs.aspx
2. Click the add text tool and insert "One"
3. Click the add text tool and insert "Two"
4. Click the add text tool, write "Three" and cancel/close the dialog
5. Click "Undo"
6. Click "Redo"
Result: The last written "Three" string is inserted instead of the expected "Two"

When I load the radspreadsheet from an excel file, the foreground color is not loaded.

A workaround is to use the Kendo Spreadsheet widget directly which imports fore color: https://demos.telerik.com/kendo-ui/spreadsheet/server-side-import-export

Repro steps 
    go to https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/import-export/defaultcs.aspx
    add some text with specific fore color
    save the excel file
    import the excel file

Expected: there is no change

Actual: the fore color is not imported. Also, font size changes, but see the related item for that
