I have a RadGrid that is bound on the client-side. It contains a GridTemplateColumn with a label and a tooltip.
Because it's bound on the client i can only assume that I would need to dyanmically set the tooltip text there as well. My issue is that I cannot get the handle of the tooltip in the OnRowDataBound event. ...Possibly because it lies within the RadGrid. Any ideas on how to accomplish this?

The GridTemplatecolumn:

<telerik:GridTemplateColumn DataField="dataf1" HeaderText="myheading1" UniqueName="dataf1">

<asp:Label ID="Label1" runat="server" Text='hover'>

</asp:Label>

<telerik:RadToolTip ID="RadToolTip1" runat="server" TargetControlID="Label1" Width="150px"

RelativeTo="Element" Position="MiddleRight" EnableShadow="true">

</telerik:RadToolTip>

</ItemTemplate>

</telerik:GridTemplateColumn>

handle to tooltip is null

function OnRowDataBound(sender, args)

{

var tooltip = $find("RadToolTip1");
tooltip.set_text = "something new here"; //this is null!
}

RadButton and ResponseScripts issue

Hi,
I have some issues with the RadButton click event. I have an user control that has a ListView and RadButton. On the main page I set the radbutton clicke event in a declarative way by exposing the radbutton as a usercontrol property. when users click on a some other button on main page I am databinding the listview and adding a responsescript that i want to run after the ajax call. But when I click the radbutton on the usercontrol it doesnt work. But, when I take out the reponsescript it works fine. Please let me know if I am missing something.

Thanks in advance!!!

Clientside advanced forms (reloading form data)

Hello,

I am using the scheduler in a project with a webservice and a custom dbschedulerprovider (all working very nicely).

I am now making a custom advanced form to handle the appointment data. My problem is that I need to reload the controls on my form as the data loaded (in the combo boxes) changes in relation to which appointment has been opened.

I have been looking at the OnClientFormCreated event for a way to do this. This is what is in the example.

function OnClientFormCreated(scheduler, eventArgs) {

// Create a client-side object only for the advanced templates

var mode = eventArgs.get_mode();

if (mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert ||

mode == Telerik.Web.UI.SchedulerFormMode.AdvancedEdit) {

// Initialize the client-side object for the advanced form

var formElement = eventArgs.get_formElement();

var templateKey = scheduler.get_id() + "_" + mode;

var advancedTemplate = schedulerTemplates[templateKey];

if (!advancedTemplate) {

// Initialize the template for this RadScheduler instance

// and cache it in the schedulerTemplates dictionary

var schedulerElement = scheduler.get_element();

var isModal = scheduler.get_advancedFormSettings().modal;

advancedTemplate = new window.SchedulerAdvancedTemplate(schedulerElement, formElement, isModal);

advancedTemplate.initialize();

schedulerTemplates[templateKey] = advancedTemplate;

}

// Are we using Web Service data binding?

if (!scheduler.get_webServiceSettings().get_isEmpty()) {

// Populate the form with the appointment data

var apt = eventArgs.get_appointment();

var isInsert = mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert;

var editSeries = eventArgs.get_editingRecurringSeries();

advancedTemplate.populate(apt, isInsert, editSeries);

}

I would be grateful if you could direct me to more detailed information regarding this or any examples that demonstrate my required functionality.

Best Regards,
Michael

radupload check image width and height

protected void rauIMAGE_ValidatingFile(object sender, Telerik.Web.UI.Upload.ValidateFileEventArgs e)

{

//we will check image height and width

if (rauIMAGE.UploadedFiles.Count > 0)

{

foreach (UploadedFile theFile in rauIMAGE.UploadedFiles)

{

//Stream stream = theFile.InputStream; (when uncomment problem occurs)

//using (System.Drawing.Bitmap myImage = new System.Drawing.Bitmap(stream,false))

//{

// if (myImage.Width > 128 || myImage.Height > 128)

// {

// master.ShowMessage("Image bigger than width :300px by height: 100px not allowed", null, "");

// e.IsValid = false;

// }

//}

//e.SkipInternalValidation = true;

}

In the above code block I try to determine uploaded image width and height to be able to prevent from uploading image size larger than (128x128)
but when use inputstream to create new image object I come across with strange error. Also

System.Drawing.Bitmap myImage = new System.Drawing.Bitmap(stream,false) error
System.Drawing.Bitmap myImage = new System.Drawing.Bitmap(theFile.InputStream,false) error
System.Drawing.Bitmap myImage = new System.Drawing.Bitmap(128,128) no error when also comment this line--> (Stream stream = theFile.InputStream)

Do you have any idea about that strange error ??

panelbar is not collapsing

I have a panel bar in a user control. I can see all the items in the panel bar and expand it too, but I cannot collapse the panel bar. below is my code

if (!Page.IsPostBack)

{

CSModel.CsMenu menu = new CSModel.CsMenu();

IList<CsMenuSection> getMenuItems = menu.GetAllItems();

foreach (CsMenuSection section in getMenuItems)

{

RadPanelItem newItem = new RadPanelItem(section.Text);

RadPanelBar1.Items.Add(newItem);

CsMenuItem item = new CsMenuItem();

for (int i = 0; i <= section.MenuItems.Count-1; i++)

{

RadPanelItem childItem = new RadPanelItem(section.MenuItems[i].Text);

RadPanelItem InternalChildItem = new RadPanelItem();

// add to the child

childItem.Items.Add(InternalChildItem);

// set the content

InternalChildItem.Value = section.MenuItems[i].Link;

newItem.Items.Add(childItem);

}

My .aspx page is like this

<table>

<tr>

<td>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" ExpandMode="FullExpandedItem" Height="250px" >

</telerik:RadPanelBar>

</td>

</tr>

</table>

My CsMenu section looks like this

public IList<CsMenuSection> GetMenuItems()

{

// go to DB to find menu items.

CsMenuSection section = new CsMenuSection("DataReview","");

section.AddMenuItem(new CsMenuItem("Score rep", "/RepScore/Index"));

section.AddMenuItem(new CsMenuItem("Something else", "/something/something"));

CsMenuSection section2 = new CsMenuSection("Section 2", "");

section2.AddMenuItem(new CsMenuItem("Sample", "/repScoring/Selectreps"));

_menu_item_list.Add(section);

_menu_item_list.Add(section2);

return MenuItemList;

}

How can I disable insert on an item by item basis?

Hello,

I'm using the automatically generated edit and insert controls for the RadTreeView and so far everything is working out fine, except that I'm stuck on one thing.

I would like to limit the number of nested inserts a user can do by disabling and hiding the insert on certain rows (which will be determined programatically in the ItemDataBound Event).

This is just a simple example of what I'd like to do. Basically if the "level" of the item is 4, I would like to disable and hide the insert.

protected void ItemDataBound(object sender, TreeListItemDataBoundEventArgs e)

{

if (e.Item.ItemType == TreeListItemType.AlternatingItem || e.Item.ItemType == TreeListItemType.Item)

{

TreeListDataItem item = e.Item as TreeListDataItem;

int level = (int)DataBinder.Eval(item.DataItem,"Level");

if (level == 4)

{

item["InsertCommandColumn"].Enabled = false;

}

The item["InsertCommandColumn"].Enabled kind of works, but it keeps the control visible and confusing for the end user.

If I hide the Cell entirely, all of the other cells shift over to fill the void.

Is there a more graceful way to disable an automatically generated insert button on a row by row basis?

Q1 2011 - File Explorer. AsyncUpload ??

Hello Telerik,

I read that in the latest release you added AsyncUpload to the File Explorer.

http://www.telerik.com/products/aspnet-ajax/whats-new.aspx
RadFileExplorer - With Q1 2011 release, the Telerik ASP.NET AJAX FileExplorer component adds valuable features, such as AsyncUpload and filter textbox for grid. See demo

I went to the "see demo" page, but all I saw was the new filter.

When are you going to have a demo of the new feature? Do you have any example source code?

Thanks,

-Josh
