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;

}

[Solved] 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?

[Solved] 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

Splitbutton show contextmenu

I have been playing around with the button with splitbutton enabled, trying to show a contextmenu.

having read articles on the subject none seem to do the trick, or atleast not the way i want it to.

setting the target element of contextmenu only applies when user right-clicks, and is catched on the whole button, not the splitbutton.

Using this script i get
"Unable to get value of the property 'relatedTarget': object is null or undefined"

function showMenu(e)

{

var contextMenu = $find("<%ctl00_phHead_pbCaseDetails_i0_i0_RadContextMenu1");

if ((!e.relatedTarget) || (!$telerik.isDescendantOrSelf(contextMenu.get_element(), e.relatedTarget)))

{

contextMenu.show(e);

}

$telerik.cancelRawEvent(e);

}

<telerik:RadButton ID="btnCaseSave" runat="server" EnableSplitButton="True" AutoPostBack="false"

Skin="Windows7" Text="Spara" OnClientClicked="showMenu(event)">

</telerik:RadButton>

<telerik:RadContextMenu ID="RadContextMenu1" runat="server" Skin="Windows7">

<Targets>

<telerik:ContextMenuElementTarget ElementID="ctl00_phHead_pbCaseDetails_i0_i0_btnCaseSave" />

</Targets>

<Items>

<telerik:RadMenuItem Text="Spara och avsluta">

</telerik:RadMenuItem>

</Items>

</telerik:RadContextMenu>

How do i get the contextmenu to show on left-click on splitbutton only, and keep postback method on the main button?

[Solved] Can I have popup edit form and in-place edit on double click within the same grid?

I am currently builting a resource management app. I have a row of data which consists of a resource name and their hours per month for 12 months.

I want the user to be able to edit each month's hours by double click and then edit in place (e.g. http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultcs.aspx) - this works fine.

However, I also want to be able to edit the resource name in a popup window, as I need to have related comboboxes to select the resource name.

Is this possible? I only seem to be able to set the EditMode at MasterTableView level - which means one or the other, but not both.

Any help would be greatly appreciated!
