I have a RadComboBox setup to display Checkboxes, like this:

					<telerik:RadComboBox ID="cmbLocation" Name="Location" runat="server" DataTextField="Key" DataValueField="Value" TabIndex="18" Width="214"
						OnClientDropDownClosing="OnClientDropDownClosing" MarkFirstMatch="true" AllowCustomText="false">
						<ItemTemplate>
							<asp:CheckBox runat="server" ID="chkLocation" Text='<%# Eval("Key")%>'/> 
						</ItemTemplate>                    
					</telerik:RadComboBox>

The ComboBox is then simply bound to a List<KeyValuePair<string,int>> datasource in code behind.

I need to add an item to the top of the list that simply says "ALL". I really don't need a Checkbox in this item, for what it is worth.

I am currently doing this:

            cmbLocation.Items.Insert(0, new RadComboBoxItem(Common.All, "-1"));

This works more or less. When I run the app, the ComboBox reads "All". But there is also a blank checkbox in the first position. I don't want that to be there. But I do need to be able to tell if All is selected.

WHen I look in the generated HTML code, I see that the first item is only an <input> (type of checkbox). All the rest of the items have both a <label> and an <input>.

What's the right way to add a default item here?

Send both selectedText & Value to requestItems event

Hi all,
Please advise.
After selected 1stCombo, then bind 2ndCombo base on 1stCombo selected value & text.
Thant's why I need to send both selectedText & Value from ClientScript at ClientSelectedIndexChange.

My code is as below

<telerik:RadComboBox ID="Cbo1" runat="server"

CssClass="label" Label="Combox1 :" Skin="WebBlue"

OnClientSelectedIndexChanging="LoadCbo2l"

OnItemsRequested="Cbo1_ItemsRequested"

onclientitemsrequested="ItemsLoaded" ViewStateMode="Enabled"

></telerik:RadComboBox>

<telerik:RadComboBox ID="Cbo2" Runat="server" CssClass="label" Label= "Combox2 :"

Skin="WebBlue" OnItemsRequested="Cbo2_ItemsRequested"

OnClientItemsRequested="ItemsLoaded" ViewStateMode="Enabled">

</telerik:RadComboBox>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function LoadCbo2(combo, eventArqs) {

var 2ndCombo;

var item = eventArqs.get_item();

2ndCombo.set_text("Loading...");

if (item.get_index() > 0) {

Cbo2.requestItems(item.get_value(), false);

}

else {

2ndCombo.set_text(" ");

2ndCombo.clearItems();

}

</script>

</telerik:RadCodeBlock>

With this I only get selected value at Cbo2_ItemsRequested event, when I try to get with Cbo1.SelectedItem.Text directly, the text I selected is not yet there.
How can I get both, please?

Thanks and best regards

Can't find ASP.NET Checkbox in Radgrid row with Client side Javascript

I can't find ASP.NET Checkbox in Radgrid row with Client side Javascript in the RowDatabound event. I would think this would be simple to do. I must be doing something silly.

I am able to find a Telerik control but not a ASP.NET control

function RadGrid1_RowDataBound(sender, args) {

// this works

var radTextBox1 = args.get_item().findControl("LastName"); // find control

radTextBox1.set_value(args.get_dataItem()["Enabled2"]);

// This does not work

var MyCheckbox = args.get_item().findControl("CheckBoxEnabled"); // find control

}

Here is the grid code

<telerik:GridTemplateColumn HeaderText="Enabled" AllowFiltering="False">

<HeaderStyle Width="40px" />

<ItemStyle Width="40px" />

<ItemTemplate>

<telerik:RadTextBox ID="LastName" runat="server" Width="80px" />

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

</ItemTemplate>

</telerik:GridTemplateColumn>

Thanks

Contextmenu on a custom command.

Hi.

Is there a way to make a custom command show a context menu?
Just as if the command icon was the root level of a dropdown menu.

Thank you

Remove Column error - Index was out of range.

Telerik.Web.UI : runtime = v2.0.50727, ver = 2008.2.723.20

Error when removing column from grid.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Process I am going through:

1. user selects add column on the page
2. Post back, add column to datasource
3. rebind grid
(grab data from datasource, clear columns from grid, add all current columns)
4. user selects delete column
5. confirm delete
6. postback, delete column from datasource
7. rebind grid
(grab data from datasource, clear columns from grid, add all current columns)

This works if all of this is done continuously. However, if I navigate off of this page at before step 4 and return to the page and continue, then I receive the error above.

Note: on NeedDataSource event I am setting datagrid.DataSource to the System.Data.DataTable

i dont know if it has to do with the viewstate? i tried to provide as much info as i can, let me know if anything else is required.

$find doesn't find

Hello everybody.
I can't succed in find anything with $find('objectID') method.
I'm using a webapp structure consisting of one page that loads dynamically a couple of UserControls implementing various functions.
On the other hand document.getElementById('objectID') give me back the object, so I'm pretty sure the objectID is correct.
Any idea?

Thanks in advance

Andrea
