DataGrid issues

Hi.

I have a RadGrid with the following settings:

<telerik:RadGrid ID="genericGrid" runat="server" AutoGenerateColumns="false" AllowAutomaticDeletes="false"

AllowSorting="true" AllowAutomaticInserts="false" AllowAutomaticUpdates="true" OnDataBound="DataBoundGenericGrid"

AllowCustomPaging="true" PageSize="100" AllowPaging="True" AutoGenerateEditColumn="true"

AllowFilteringByColumn="true" AllowMultiRowSelection="true" OnUpdateCommand="ItemUpdatedEvent"

OnCancelCommand="ItemCanceledHandler" OnInsertCommand="ItemInsertedEvent" OnEditCommand="ItemEditHandler"

OnItemDataBound="ItemDataBoundEvent" OnNeedDataSource="GridNeedDataSource" Style="height: 600;

width: 100%">

<ClientSettings AllowDragToGroup="true" AllowGroupExpandCollapse="true">

<Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

<ClientEvents OnRowDblClick="RowDblClick" />

</ClientSettings>

<MasterTableView AutoGenerateColumns="true" AllowAutomaticDeletes="false" AllowFilteringByColumn="true"

AllowAutomaticInserts="false" AllowAutomaticUpdates="true" GridLines="Vertical"

TableLayout="Fixed" GroupLoadMode="Client" EditMode="InPlace" />

</telerik:RadGrid>

When we autogenerate columns from a DataTable everything works as expected:

genericGrid.DataSource = table.DefaultView;

http://dl.dropbox.com/u/4552022/workinggrid.png

But when i try to add the columns in code:

foreach (var gridColumn in _gridColumns)

{

genericGrid.Columns.Add(gridColumn);

}

genericGrid.DataSource = table.DefaultView;

I get this:

http://dl.dropbox.com/u/4552022/notworkinggrid.png

And also, doubleklicking a row is supposed to give editmode:
http://dl.dropbox.com/u/4552022/edit.png

But when adding columns manually it gives this error:
http://dl.dropbox.com/u/4552022/error.png

When manually creating columns, they are created like this:

var dropDownColumn = new GridDateTimeColumn()

{

DataField = tableDefDto.ColumnId

};

The reason for doing this manually, is to enable the possiblity for dropdownColumns.

Any ideas?

Declaring RadWindow on BasePage class

Hello,

I have the following code which declares a radwindow in BasePage class, its works fine in aspx pages, but I can't use it in User Controls and Master Pages:

string BaseRadWindowID

{

get

{

return "UniqueBaseRadWindowID";

}

RadWindow window = new RadWindow();// Create a enw Window

RadWindow BaseRadWindow

{

get

{

return window;

}

protected override void OnInit(EventArgs e)

{

this.window = new RadWindow();// Create a enw Window

window.ID = BaseRadWindowID;// the id of the RadWindow;

this.Form.Controls.Add(window);// Add it to the page

base.OnInit(e);

}

public void ShowBaseRadWindow(bool visibleOnPageLoad, string navigationUrlQueryString)

{

BaseRadWindow.Width = Unit.Pixel(450);

BaseRadWindow.Height = Unit.Pixel(150);

BaseRadWindow.VisibleOnPageLoad = true;

BaseRadWindow.VisibleStatusbar = true;

BaseRadWindow.ReloadOnShow = true;

BaseRadWindow.Modal = true;

BaseRadWindow.Behaviors = WindowBehaviors.Close;

BaseRadWindow.Style.Add("z-index", "10000");

BaseRadWindow.NavigateUrl = "~/Pages/Messages/Default.aspx" + navigationUrlQueryString;

BaseRadWindow.VisibleOnPageLoad = visibleOnPageLoad;

}

I call the window in the aspx pages in this way:

this.ShowBaseRadWindow(true, string.Empty);

Please, I need your help in order to call the window and show it in User Controls and Master Pages.
It is very appreciated to send me the modified code.

Regards,
Bader

Pop-up Modal Edit Form Isn't Very Modal

Hello,

I'm not sure if this is intended behavior, but it appears the pop-up modal edit form isn't so modal. When in modal mode, you can actually tab through all the page controls. If the control is a link and you press the enter key and it will post to the link.

You can try it out on the demo site:

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/popupeditform/defaultcs.aspx

I've attached an image of two modal windows open at the same time.

Next and Previous month navigation not working after changing theMultiviewColumn =2

Hi,

We are using Radscheduler in our project. We need to show the dropdown calendar near the Header "Today" with 2 months column in a row. so we made the following changes.

RadCalendar popupCalendar = RadScheduler1.FindControl("SelectedDateCalendar") as RadCalendar;
popupCalendar.AutoPostBack = true;
popupCalendar.MultiViewColumns = 2;

This code shows 2 months but the problem now is, we are not able to navigate to next, previous, fast next and fast previous navigation.
When we click the next button nothing happens. It seems the Autopost back is not working even we gave that in our code.

Please help us to resolve this issue.
