We were using this code to set a value in the editor from a custom dialog:

Telerik.Web.UI.Editor.CommandList["BackgroundImage"] = function (commandName, editor, commandArgs) {

var argument = Telerik.Web.UI.Editor.CommandList._getLinkArgument(editor);

Telerik.Web.UI.Editor.CommandList._getDialogArguments(argument, "A", editor, commandName);

var callbackFunction = Telerik.Web.UI.Editor.CommandList.getCallbackFunction(commandArgs, function (sender, args) {

if (!args) {

//alert("No args!");

return false;

}

var selectedItem = args.get_value();

var path = args.value.getAttribute("src", 2);

var style = editor.get_contentArea().style;

style.backgroundImage = 'url(' + path + ')';

document.getElementById('<%=hdnBackgroundImage.ClientID %>').value = path;

});

editor.showDialog("backgroundImageManager", argument, callbackFunction);

return false;

};

We upgraded to the latest Rad tools and now get an error on "args.value.getAttribute is not a function".

What can we change to get that path value from the dialog?

RadGrid not opening popup editor when no records

Hi All

I've a radgrid displaying a list of customers. In the grid, I have a command button that's supposed to open a popup editor to add new customers. For some reason, the popup does not open. It shows a small flicker and nothing happens. Strangely enough, if I go into the database, manually add a customer record and refresh the grid, I'm able to open the editor.

Any help is most welcome!

Here is the grid definition in my ascx:
========================================

<telerik:RadGrid ID="CustomerList" runat="server"

GroupingEnabled="False" ShowStatusBar="True" OnPreRender="CustomerList_PreRender"

DataSourceID="CustomerDataSource"

OnItemCommand="CustomerList_ItemCommand" OnItemDataBound="CustomerList_ItemDataBound"

OnInsertCommand="CustomerList_InsertCommand" OnItemInserted="CustomerList_ItemInserted"

OnItemEvent="CustomerList_ItemEvent" >

<MasterTableView DataKeyNames="CustomerId" DataSourceID="CustomerDataSource"

AllowPaging="true" AutoGenerateColumns="False"

GridLines="None" EditMode="PopUp" ShowFooter="True"

InsertItemDisplay="Bottom" CommandItemDisplay="TopAndBottom" >

<CommandItemSettings AddNewRecordText="Add Customer" />

<Columns>

<telerik:GridBoundColumn DataField="CustomerId" DataType="System.Int32" FilterControlAltText="Filter CustomerId column" HeaderText="CustomerId" ReadOnly="True" SortExpression="CustomerId" UniqueName="CustomerId">

<ColumnValidationSettings>

<ModelErrorMessage Text="" />

</ColumnValidationSettings>

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="CustomerName" FilterControlAltText="Filter CustomerName column" HeaderText="CustomerName" SortExpression="CustomerName" UniqueName="CustomerName">

<ColumnValidationSettings>

<ModelErrorMessage Text="" />

</ColumnValidationSettings>

</telerik:GridBoundColumn>

<telerik:GridEditCommandColumn UniqueName="EditCommandColumn">

<ItemStyle Width="20px" Font-Underline="true" />

</telerik:GridEditCommandColumn>

</Columns>

<NoRecordsTemplate>

No customers have been created yet.

</NoRecordsTemplate>

<EditFormSettings EditFormType="WebUserControl" CaptionDataField="CustomerName"

UserControlName="~/UserControls/CustomerEditor.ascx"

>

<EditColumn UniqueName="EditCommandColumn" HeaderButtonType="TextButton">

</EditColumn>

<PopUpSettings ScrollBars="None" Width="581"/>

</EditFormSettings>

<PagerStyle Mode="NextPrevAndNumeric" Position="Bottom" />

</MasterTableView>

</telerik:RadGrid>

Really basic question

Hi All,
I am completely new to AJAX.
This is the first program I have come across and I must say I am confused..

Few of my queries are below:

I wrote below code in a notepad and saved as html. But I don't know where to place the "ajax_info.txt" file. It dint work when I placed it in the same folder as the .html file
Also I don't understand and which response are we collecting through xmlhttp.responseText. Because its only on the next line (xmlhttp.open("GET","ajax_info.txt",true) that we actually mention the url/path to which we are trying to connect. So whom are we trying to get response from in : xmlhttp.open("GET","ajax_info.txt",true

I know its tooooo basic but just cant get a hold of it.

<!DOCTYPE html>
<html>
<head>
<script>
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
    }
}
xmlhttp.open("GET","ajax_info.txt",true);
xmlhttp.send();
}
</script>
</head>
<body><div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadXMLDoc()">Change Content</button></body>
</html>

RadAjaxLoadingPanel without RadAjaxManager

I have a master page with many pages and usercontrols.

I have made great use of RadAjaxManager & proxies on my pages and user controls, however, there are a few events in the master page itself. Since we can only have a single RadAjaxManager on a given rendered page, I cannot place a RadAjaxManager on the master page or I will have to move up all the RadAjaxManager and the OnAjaxRequest events up as well, which is not doable. Further, the OnAjaxRequest needs to be placed in the Manager and not the proxy, which further makes moving to a single manager on the master page not achievable.

How can I leverage a RadAjaxLoadingPanel on the master page for it's events based on this scenario

Thanks in advance

Post Back when closing combobox

I have a radcombobox CheckBoxes="True" and AutoPostBack="True" because I need server side code to execute after the user makes her selections. However, the postback is occurring every time a user checks a box and then it closes the combobox. The user wants the combobox to stay open and I don't want the postback to occur until the user is finished and clicks off of the combobox. I am experimenting with using the combobox's OnClientBlur event and then doing a postback like this: __doPostBack(objName, "ItemChecked"); But I'm struggling to get it to work and not confident that's the right path.

[Solved] Unable to hide Label in RadGrid in Edit Mode

Hi,

Why is it not possible to hide the label during edit mode?

For instance, in the following code, "lblInvoiceDetailID" is not hidden even when visible property is set to false in edit mode....

<telerik:GridTemplateColumn DataField="InvoiceDetailID" HeaderText="InvoiceDetailID" UniqueName="InvoiceDetailID" Display="False">

<asp:Label ID="lblInvoiceDetailID" runat="server" Text='<%# Bind("InvoiceDetailID") %>' Visible="false"> </asp:Label>

</ItemTemplate>

<asp:TextBox ID="txtInvoiceDetailID" Text='<%# Bind("InvoiceDetailID") %>' runat="server" ReadOnly="true" Visible="false"></asp:TextBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Any help is highly appreciated.

Many thanks.

Grid contents not wrapping

Hi,

We are using telerik grid where we display data entered by our users. We have set fixed column widths and enabled wrap.

What happens is if there is a word w/o space it does not wrap, rather it gets cut while being displayed.

What is the solution for this - e.g. any grid tools wraps data automatically

Thanks

Anand

Collapse all docks in a dock zone excepted the dock that fired the OnClientCommand ExpandCollapse

Hi,

i am facing a really trival problem but i am not able to sort this out. I am sure, anyone of you guys can give me a clue!
I have a dock zone that contains 4 docks.
On the initial load all dock are collapsed.
There are some other controls on that page that expand one of the described docks for showing information.

My issue is really simple. At one time, i want to have just one dock expanded. So if another controls expands i.e. dock2, all other docks shall be collpased.

At the moment i am trying the figure this out by using the OnClientComment event to do the necessary stuff, but with no avail.

Thanks a lot..
Marc
