Dynamic column problem

Hello,

I am dynamically adding a GridTemplateColumn to a radgrid but the problem is that on each postback a new empty column is added to the grid with header "Action". Any help?

protected void Page_Init(object sender, EventArgs e)
{

   var col = this.requestGrid.MasterTableView.Columns.FindByUniqueNameSafe("ActionId");

GridTemplateColumn actionColumn = new GridTemplateColumn();
this.requestGrid.MasterTableView.Columns.Add(actionColumn);
actionColumn.ItemTemplate = new ActionTemplate("actionID");
actionColumn.DataField = "ActionID";
actionColumn.HeaderText = "Action";
}

The Indent command brakes the bulleted/numbered list

Hi,

Scenario:

1. Set to the editor the "<ul><li>1</li><li>2</li><li>3</li></ul>" value in the HTML mode.

2. Place the cursor exact after the second element of the list in the Design mode.

3. Click the Indent button.

4. Choose again the HTML mode.

Result:

<ul>

<li>1</li>

<ul>

<li>2</li>

</ul>

<li>3</li>

</ul>

It is invalid HTML as the ul tag may contain only the il child tags.

Expected result:

<ul>

<li>1</li>

<li>

<ul>

<li>2</li>

</ul>

</li>

<li>3</li>

</ul>

or

<ul>

<li>1

<ul>

<li>2</li>

</ul>

</li>

<li>3</li>

</ul>

Do you have a workaround for the issue?

Thanks,

Ivan

Custom Image Manager Dialog Broken

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>

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.
