The users want the TextBox to select its contents when the user clicks into the TextBox.

I tried this code:

Private Sub RadTextBox1_Enter(sender As Object, e As System.EventArgs) Handles RadTextBox1.Enter

Dim tb = TryCast(RadTextBox1.TextBoxElement.TextBoxItem.HostedControl, TextBox)

tb.SelectAll()

End Sub

This works when the user Tabs into the TextBox, but not when the user clicks into the TextBox.

Is there a way to select the text when the user clicks into the TextBox?

Thanks!

Refreshing self referencing grid causes error

I have a grid that shows data that is self referencing. The data is a simple List<> based collection of objects that have an Id and ParentId properties (among others). [Using Telerik.WinControls.UI.RadGridView version 2012.3.1211.40]

Below is the error information:

Object reference not set to an instance of an object.

Does anyone have any ideas on how to troubleshoot this?

Thanks!

RadMenu and RadRibbon

Hi

Is there a way to use a plain old RadMenu and a RadRibbonBar (but not with its own menu and title bar and everything) at the same time?

I would like to have the look of the Ribbon bar (mix of large and small images) but my users are not ready to give away the traditional menu at the top of the form (not the one hidden like the RadApplicationMenu!).

I have tried the RadCommandBar and I can't get everything I want (mixed of images sizes, section caption, ...)

RibbonBar

How to load Controls from RadDock using WebUserControl?

I am having a hard time trying to load my controls inside a RadDock that uses ascx.\

This is my code (it is same as the Portal Demo)

protected void ButtonAddDock_Click(object sender, EventArgs e)

{

RadDock dock = CreateRadDock();

RadDockZone dz = RadDockZone1;

RadDockLayout1.Controls.Add(dock);

dock.Dock(dz);

CreateSaveStateTrigger(dock);

dock.Tag = "Templates/NewQuiz.ascx";

LoadWidget(dock);

}

private void LoadWidget(RadDock dock)

{

if (string.IsNullOrEmpty(dock.Tag) || dock.Closed)

{

return;

}

Control widget = LoadControl(dock.Tag);

widget.EnableViewState = false;

dock.ContentContainer.Controls.Add(widget);

}

protected void btnSaveDraft_Click(object sender, EventArgs e)

{

string[] questions = {};

int x = 0;

foreach (RadDock dock in RadDockLayout1.RegisteredDocks)

{

RadTextBox txtQuestion = (RadTextBox)dock.ContentContainer.FindControl("txtQuestion");

questions[x]= txtQuestion.Text;

x++;

}

And here is my ASCX

<center style="padding-top: 15px;">

<table style="text-align: justify;">

<tr>

<td style="width: 15%;">

Question:

</td>

<td>

<telerik:RadTextBox ID="txtQuestion" runat="server" Width="100%">

</telerik:RadTextBox>

</td>

</tr>

<tr>

<td style="width: 15%;">

Help Text:

</td>

<td>

<telerik:RadTextBox ID="txtHelp" runat="server" Width="100%">

</telerik:RadTextBox>

</td>

</tr>

<tr>

<td style="width: 15%;">

Mandatory:

</td>

<td>

<asp:CheckBox ID="chkMandatory" runat="server" />

</td>

</tr>

<tr>

<td style="width: 15%;">

Question Weight:

</td>

<td>

<telerik:RadTextBox ID="txtWeight" runat="server" Width="30px" Text="1">

</telerik:RadTextBox>

</td>

</tr>

<tr>

<td style="width: 15%;">

Question Type:

</td>

<td>

<telerik:RadComboBox ID="ddlType" runat="server" AutoPostBack="True">

<Items>

<telerik:RadComboBoxItem runat="server" Selected="True" Text="--Select Question Type--"

Value="--Select Question Type--" />

<telerik:RadComboBoxItem runat="server" Text="Multiple Choice - Radio Button" Value="Multiple Choice - Radio Button" />

<telerik:RadComboBoxItem runat="server" Text="Multiple Choice - Check Box" Value="Multiple Choice - Check Box" />

</Items>

</telerik:RadComboBox>

</td>

</tr>

</table>

</center>

The code in my aspx can't find the txtQuestion textbox.

Unbound PivotGrid

Hi,

Are there any examples of a Unbound PivotGrid? I would like to have PivotGrid that looks like a Property Grid.
I need to use PivotGrid because I need multiple rows. I need to add my own rows.
I would like to have a PivotGrid that has categories (groups) and images in the individual rows.

I have not found any examples for adding rows manually.

Below is an example of what I want the grid to look like.

Thanks
Steve Morrow

ilmerge & Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True

I have a few questions regarding ilmerge & Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True. Any help would be greatly appreciated.

My application startup object is Sub Main. Should Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True still be placed in the static constructor of the first form that is created and loaded?
My first form is a login screen that is disposed once you have successfully logged in. Will this cause issues with Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True?
I am able to successfully merging Telerik.Reporting.dll, Telerik.ReportViewer.WinForms.dll, Telerik.WinControls.dll, Telerik.WinControls.GridView.dll, Telerik.WinControls.RadDock.dll, Telerik.WinControls.Themes.Office2010Black.dll, Telerik.WinControls.Themes.Office2010Blue.dll, Telerik.WinControls.Themes.Office2010Silver.dll, Telerik.WinControls.UI.dll, TelerikCommon.dll and my exe both. The merged and the standalone application run without error when Telerik.WinControls.RadTypeResolver.Instance.ResolveTypesInCurrentAssembly = True. Isn’t the built executable supposed to return an exception?

Determining Line Spacing at Caret Position

When creating or editing a document using the RadRichTextBox control, I've allowed the user to change the line spacing and spacing before and after a paragraph. The user can then select one or more paragraphs and change these settings, which only apply to the selected area.

How can I determine at runtime what the line/paragraph spacing is for the paragraph at the current caret position?

Any help is greatly appreciated.

Problems with Telerik toolbox items

Hi,

I just reinstalled VS2012 due to some strange malfunction (I couldn't add controls to forms from the toolbox), and at the same time, i uninstalled Telerik Winforms controls version 2010_3_10_1215 and installed version 2012_3_1211, which we use in our solution.
My problem is, that in the Telerik controls Toolbox tab, most controls are greyed out, and appears twice.
I have tried the TelerikToolboxCleaner from one of the other posts, but apparently it works with VS2010, not VS2012.
I have also used the Telerik Toolbox Configurator.
I wan't to have all controls available one time.

I'm not too fond of resetting the toolbox, because I fear it might mess up a lot of other things.

How do I fix this?

I hope you can help me resolve this issue.

BR
Henning
