<telerik:RadButton ID="btnUSDelete" runat="server" Skin="Sunset" Text="Delete"

ValidationGroup="UserSettings" onclick="btnUSDelete_Click" OnClientClicking="OnClientClicking123">

</telerik:RadButton>

<script type="text/javascript">

function OnClientClicking123(sender, args)

{

var callBackFunction = Function.createDelegate(sender, function(argument)

{

if (argument)

{

this.click();

}

});

var text = "Are you sure you want to delete this record?";

return confirm(text, callBackFunction, 300, 100, null, "Title");

args.set_cancel(true);

How to disable and hide a single checkbox?

I am receiving a dictionary which I am binding to the combobox control. I wrote a loop that iterates through the items collection and changes some flagged items to a separator item. The problem is, if checkboxes are enabled, the seperator also receives a checkbox which sort of defeats the functionality. Is there something I could add to my loop that will disable the checkbox on these items?

Here is an example of the code that I'm using to create the seperators:

public static void FormatList(ref RadComboBox assignees)

{

for (int i = 0; i < assignees.Items.Count; i++)

{

if (assignees.Items[i].Text == "people")

{

assignees.Items[i] = new Telerik.Web.UI.RadComboBoxItem("Assign to Person:");

assignees.Items[i].IsSeparator = true;

}

if (assignees.Items[i].Text == "group")

{

assignees.Items[i] = new Telerik.Web.UI.RadComboBoxItem("Assign to Group:");

assignees.Items[i].IsSeparator = true;

}

Unable to update underlying datasource

Hello,

I am using a RadGrid and I am binding an Arraylist of type "myClass" (name property, id Property and several boolean properties). I am using this arrayList as my datasource for the grid and I am using checkbox columns for the boolean properties.

public interface IMyClass

{     

           int EntityID{get; set; }

string Name { get; set; }

bool IsPrivateReader { get; set; }

bool CanShare { get; set; }

}

The issue I am having is that when I check a checkbox it does not update the object it is bound to. Please help. Here is my grid:

<telerik:RadGrid ID="dg"

runat="server"

AllowSorting="True"

AllowAutomaticUpdates="True"

Skin="WebBlue"

EnableAJAX="true"

EnableOutsideScripts="true"

GridLines="None">

<ClientSettings>

<Selecting CellSelectionMode="None" />

</ClientSettings>

<MasterTableView AllowAutomaticDeletes="true" AutoGenerateColumns="False"

CommandItemDisplay="None" DataKeyNames="EntityID" Width="100%">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn>

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn>

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="EntityID" HeaderStyle-HorizontalAlign="Center" HeaderText="Entity ID" ItemStyle-HorizontalAlign="Left" SortExpression="EntityID">

<HeaderStyle HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Left" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Name" HeaderStyle-HorizontalAlign="Center" HeaderText="Name" ItemStyle-HorizontalAlign="Left" SortExpression="Name">

<HeaderStyle HorizontalAlign="Center" />

<ItemStyle HorizontalAlign="Left" />

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn headertext="Private Reader" uniquename="PrivateReaderColumn">

<itemtemplate>

<asp:CheckBox ID="cbxPrivateReader" runat="server" checked='<%# Eval("IsPrivateReader") %>' />

</itemtemplate>

<edititemtemplate>

<asp:CheckBox ID="cbxPrivateReader" runat="server" checked='<%# Bind("IsPrivateReader") %>' />

</edititemtemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn headertext="Share" uniquename="SharedColumn">

<itemtemplate>

<asp:CheckBox ID="cbxShare" runat="server" checked='<%# Eval("CanShare") %>' />

</itemtemplate>

<edititemtemplate>

<asp:CheckBox ID="cbxShare" runat="server" checked='<%# Bind("CanShare") %>' />

</edititemtemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn AllowFiltering="true" HeaderText=" "

Reorderable="true" ShowSortIcon="true" SortExpression="Name">

<ItemTemplate>

<asp:ImageButton ID="btnDelete" runat="server" CausesValidation="False"

CommandName="DeleteSelected" ImageUrl="~/Images/Delete.gif"

OnClientClick="return GetUserConfirmForItemDelete(event);"

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableTheming="True" Skin="WebBlue">

<CollapseAnimation Duration="200" Type="OutQuint" />

</FilterMenu>

</telerik:RadGrid>

This is my datasource:

protected void Page_Load(object sender, EventArgs e)

{

if(!Page.IsPostBack)

{

ViewState["DataSource"] = new ArrayList();

SetInitialJavaScriptFunctions();

}

private ArrayList DataSource { get { return (ArrayList)ViewState["DataSource"]; }





private
 
 
 void BindDataGrid(string strSortExpression = "", SortDirection eSortDirection = SortDirection.Ascending)
 
{
     dg.DataSource = DataSource;
     dg.DataBind();
}

What am I missing?

Thanks

OnClientDropDownClosed and EnableCheckAllItemsCheckBox Properties

I am using multiple RadComboBoxes to cascade selectable values. I am using the OnClientDropDownClosed client-side event to fire the server-side ItemsRequested event to populate the next combobox in my sequence. Data for each combobox loads properly, but if I set the EnableCheckAllItemsCheckBox property to true, when I select the next combobox and before the ItemsRequested server-side event fires, I receive the following error:

"Microsoft JScript runtime error: 'this.get_checkAllCheckBoxDivElement().0.offsetHeight' is null or not an object"

Does anyone have any ideas how I can make all of these parts work together?

Thanks for any help.....

Image editor doesn't show image

Hi, I have just upgraded to the last asp.net ajax Q1 2012.215, but now I have some problem with the image editor inside to the radeditor.

With the Q3 2011 version everything was working well, but with the new version when I call Image editor from radeditor, the image it is not shown.

It is something like that the Image name is not set, infact if I click on refresh button I will get error because there is not any name on image reference.

It is changed somenthing from Q3 2011? because I can't find any solution to solve this problem.
