Hi, happy new year.

I wonder if it's possible to load image nodes from a stream retrieved from a Database, or I always have to use a valid URL image.

Best regards

Close RadWindow - Behaviors="Close"

We have a problem with the close of the RadWindow about Telerik-function (Behaviors="Close").

We use a RadWindow with the Attribute "Behaviors=Close"

<telerik:RadWindow ID="RadWindowProgramCategory" EnableShadow="true" Behaviors="Close" runat="server">

......

<asp:Button ID="ButtonCloseWindow" runat="server" Text="Close" OnClick="OnCloseWindow" />

.....

</telerik:RadWindow>

The RadWindow open with the button "ButtonOpenRadWindow".

<asp:Button ID="ButtonOpenRadWindow" Text="Hinzufügen" ToolTip="Hinzufügen" runat="server" OnClick="OnOpenRadWindow"></asp:Button>

protected void OnOpenRadWindow(object sender, EventArgs args)

{

AllVirtualCategories.SelectedIndex = -1;

UpdateCatagoryFields();

RadWindowProgramCategory.Title = App_LocalResources.CategoryDataControl_ascx.RadWindow_TitleAddCategory;

RadWindowProgramCategory.VisibleOnPageLoad = true;

RadWindowProgramCategory.Enabled = true;

RadWindowProgramCategory.Modal = true;

RadWindowProgramCategory.AutoSize = true;

String radWindowScript = JavaScript.GetJsOpenWindowIncCloseWindow(RadWindowProgramCategory, "");

ScriptManager.RegisterStartupScript(RadWindowProgramCategory, this.GetType(), "RadWindowProgramCategory", radWindowScript, true);

}

Thge Radwindow must open after the Postback. That works with

RadWindowProgramCategory.VisibleOnPageLoad = false;

We can close the Window about a another button and a server-side function.



protected void OnCloseWindow(object sender, EventArgs args) 
{ 
  RadWindowProgramCategory.VisibleOnPageLoad = false; 
  RadWindowProgramCategory.Enabled = false; 
}



When we close the RadWindow about icon on RadWindow Behaviors="Close" an we again a postback then opens the window again. 



how can we change this?



Best regards

Mixed readonly and read-write rows?

I am populating a RadGrid from a DataTable. Each of the DataRows in the DataTable has a "readonly" column with a value of true or false.

The grid currently has a GridEditCommand column, and a GridButtonColumn that triggers the "Delete" command.

What I need is for rows that display records for which "readonly" is true to be read-only. I need the icon in the GridEditCommand column to be different, and for clicking it to bring up a view-details form, instead of an edit form. And I need the link in the "Delete" GridButtonColumn to be absent.

It looks like it'd be pretty straightforward to create a table that doesn't allow the user to edit or to delete records, but I need to be able to have some rows editable and some not.

Where should I start?
