Maximizing and minimizing RadRibbonForm and resizing its contents

Hello All,
I am using a RadRibbonForm in a desktop application ,inside it there are other control like radgrid, document tabstrip,raddock etc.
I want that on maximizing the RadRibbonForm controls inside it should increase there size such that no empty space is left.and on minimizing the controls come to original size.

Is there any event or any code which matches this condition?

Please do needful.

RadDock obscured by RadMenu

I have a form with a menu (RadMenu) and a docking manager (RadDock).

radMenu is set to "Dock.Top" and radDock is set to "Dock.Fill". That puts both controls on (x,y)=(0,0)...

I want the menu to be above the docking control, obviously. How?

[Solved] Questions about ColumnChooser

First of all I want to say that your documentation about the controls is awesome in most cases - but when it comes to RadGridView ColumnChooser there are very few information. So here comes my list of questions ;)

1: Get rid of "Close" button
I want to toggle the visibility of my ColumnChooser only via a ToggleButton, nothing else. So how to get rid of the close button in ColumnChooser form border/header?

2: Hide/remove "How to use" text
I want to remove the text in ColumnChooser which tells the user how to use it. If you have many columns in ColumnChooser this text is slighty visible because of the space between the columns. Looks ugly - see attached image 'question2.jpg'.

3: Drag&Drop
When start dragging a column from ColumnChooser to GridView there is an graphical effect, that seems like I can add the column between rows. This looks really confusing and I want to remove this - see attached image 'question3.jpg'.

[Solved] Selecting text in a TextBox

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!

[Solved] 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, ...)

[Solved] 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
