[Solved] ClientSelectColumn

Consider the following grid ...

<telerik:RadGrid ID="RadGrid1"

runat="server"

AutoGenerateColumns="false"

AllowMultiRowSelection="false">

<MasterTableView>

<Columns>

<telerik:GridClientSelectColumn UniqueName="Select"

Visible="true"></telerik:GridClientSelectColumn>

<telerik:GridBoundColumn UniqueName="Name"

DataField="Name"

HeaderText="Name"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Email"

DataField="Email"

HeaderText="Email"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

Running the page with this definition on it displays a grid with a select column. The select column's header has a checkbox in it. This is all good.

Now, consider the case where the above grid should only display the select column under programmer-defined conditions. Also consider that the grid should be limited to single row selection when the select column is not visible.

The following code sets up an example for this ...

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1"

runat="server">

<telerik:RadScriptManager ID="RadScriptManager1"

runat="server">

</telerik:RadScriptManager>

<telerik:RadGrid ID="RadGrid1"

runat="server"

AutoGenerateColumns="false"

AllowMultiRowSelection="false">

<MasterTableView>

<Columns>

<telerik:GridClientSelectColumn UniqueName="Select"

Visible="true"></telerik:GridClientSelectColumn>

<telerik:GridBoundColumn UniqueName="Name"

DataField="Name"

HeaderText="Name"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Email"

DataField="Email"

HeaderText="Email"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="Button1"

runat="server"

Text="Click"

OnClick="Button1_Click"/>

</form>

</body>

</html>

using System.Collections.Generic;

using System;

public class Contact

{

public string Email { get; set; }

public string Name { get; set; }

}

public partial class Default5 : System.Web.UI.Page

{

protected void Button1_Click(object sender, EventArgs e)

{

bool currentValue = RadGrid1.Columns.FindByUniqueName("Select").Visible;

RadGrid1.AllowMultiRowSelection = !currentValue;

RadGrid1.Columns.FindByUniqueName("Select").Visible = !currentValue;

}

protected void Page_Load(object sender, EventArgs e)

{

List<Contact> contacts = new List<Contact>{

new Contact{Name = "Stuart Hemming1", Email = "sejhemming@gmail.com"},

new Contact{Name = "Stuart Hemming2", Email = "sejhemming2@gmail.com"},

new Contact{Name = "Stuart Hemming3", Email = "sejhemming3@gmail.com"},

new Contact{Name = "Stuart Hemming4", Email = "sejhemming4@gmail.com"},

new Contact{Name = "Stuart Hemming5", Email = "sejhemming2@gmail.com"},

new Contact{Name = "Stuart Hemming6", Email = "sejhemming@gmail.com"}

};

RadGrid1.DataSource = contacts;

RadGrid1.DataBind();

}

Run the page and you have a grid with 2 columns and a single button. Click the button to display the select column and to allow multirow selection. When the grid redraws, it does so with the select column displayed but no checkbox appears in the header.

Is this broken, or am I just missing something?

[Solved] A request

'tis a minor thing, but do you think you could reorganise RadGrid | Client-side API | Subscribing to Client Events | Client Events so that the events are listed in alphabetical order?

RadTootipManager with ImageMap control

Hi,

I'm wonder if it possible to display all radtootipmanager controls in the same time (It is very important for my application), for example, please view the attached image. The radtooltipmnager controls must be displayed together by openeing the page or by executing a method. Of course the user can close the tooltip manually and display it when he comes over it.
The question based on the following demos:
http://demos.telerik.com/aspnet-ajax/tooltip/examples/imagemaptooltipmanager/defaultcs.aspx
or
http://demos.telerik.com/aspnet-ajax/tooltip/examples/usingwithimagemap/defaultcs.aspx

Please, it is possible, can you explain to me how can I do that.
It is very apprecited to send me a modified code based on the above demos.

Regards,
Bader

How: Change the skins at runtime?

HI,

I have a window with content template which contains a button. The button has office2007 theme(using decorator) and the window has sunset theme.
If i specify the style at design, everything is fine. But if I try to assign the theme during run time, for the first page_load the theme does not appear for the buttons. But on later page_load it works fine.

The problem does not seem to occur if the button and the window have the same theme.

I am using the visibleOnPageLoad=true to show the window from server side.

Is there a better way to do this? My requirement is that based on different conditions, I need the appearance of the button and the window to be changed.

Regards,
Saravanan

Localizing Edit Form Labels?

All,

Is there a way to localize the labels within an auto-generated edit form? I would prefer not to have to use a web control to do this if at all possible. I have managed to assign resource file values to the grid headers easily enough, but I do not want to use the same value for the grid headers and the edit form.

Thanks,
jax

Rotator, LINQ data and AJAX Loading Panel

Hello everyone.

I'm using a Window on my page that has a Rotator in it. The Rotator is bound to a LINQ data set. It worked fine,
but then I tried to put an AJAX Loading Panel to show a "loading" image while the rotator is bound and I get the following error:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I tried using a RadCodeBlock without luck.

Here is my code:

(Main .aspx page)

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
    <script type="text/javascript">
    //<![CDATA[
        function openWin()
        {
            var oWnd = radopen("SCARLog.aspx", "RadWindow1");
        }
    //]]>
    </script>
</telerik:RadScriptBlock>

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
ReloadOnShow="true" runat="server" Skin="Hay" EnableShadow="true">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server" Behaviors="Close" NavigateUrl="Log.aspx">

    </Windows>
