Questions on UI for ASP.NET AJAX Forum

Hello,

Can someone please tell me why my datasource is not updating when using the RadGrid? I have read countless forum posts and still have been unable to solve the issue. I wanted to use the AutomaticUpdate/Delete feature, because it appeared to be "simple". I am using the grid to display a user's shopping cart contents. All I want to be able to do is allow them to update the quantity of an item in the cart, or remove it....period.

Below is my code. I have stripped it down to bare bones in hopes to find the problem, but still no luck. This is driving me NUTS!

Any help would be greatly appreciated.

Thanks,
Jim

Show/Hide a Module via Javascript

We'd have a system custom module for the editor that would contain large save/close buttons (not toolbar sizes) we'd like to show only when the editor is in full screen. I can detect the full screen toggling, but need a way to show/hide the module via javascript. Basically the same functionality that the Module Manager button does without the user clicking on that button and selecting/deselecting our module.

Any way to do this?

Controlling RadMenuItem visibility with inline code

I seem to be having a problem controlling the visibility of a RadMenuItem using inline code. I have an "Admins Only" dropdown I want to display only if a session variable test is true. I swear this used to work, but as of 2010Q3 it is not. The sample line is:

<telerik:RadMenuItem runat="server" Text="Admin" Visible='<%# iif(session("UserID") = "1", "True", "False") %>'>

The page loads up fine, but no matter the content of the session variable (empty, "1", "2", nothing), the menu is always displayed.

Any suggestions?

Problems with relationship between master table and detail table.

Need to establish the relationship between the master table and detail tables. I am using "GridRelationFields" but because ajax error. When not using the "GridRelationFields" I click to expand the detail of a record and I get all the detailed tables of all records.

I mention that each detail table differ in the number of columns and their names, each table are aggregated in a programmatic way.
How I can successfully establish the relationship between the master table and detail table?

I noted the examples online and do not help me.
Annex the image of the error in AJAX when using "GridRelationFields. "

This is my code to build the tables in detail:

DataTable datTabDatosDetalle = new DataTable();

if (ViewState["OrdCompraProdDetallesSub" + IdOrdenCompra + Skucode] == null)

{

datTabDatosDetalle = CCSMovimientoProductos.BuscarProdDetOrdenCompra_CEDIS(IdOrdenCompra, Skucode).Tables[0];

ViewState.Add("OrdCompraProdDetallesSub" + IdOrdenCompra + Skucode, datTabDatosDetalle);

}

else

datTabDatosDetalle = (DataTable)ViewState["OrdCompraProdDetallesSub" + IdOrdenCompra + Skucode];

Telerik.Web.UI.GridTableView detailTable = new Telerik.Web.UI.GridTableView(radGriOrdComDetalles);

Telerik.Web.UI.GridRelationFields relationFields_Id = new Telerik.Web.UI.GridRelationFields();

relationFields_Id.MasterKeyField = "Id";

relationFields_Id.DetailKeyField = "Id";

detailTable.ParentTableRelation.Add(relationFields_Id);

Telerik.Web.UI.GridRelationFields relationFields_Skucode = new Telerik.Web.UI.GridRelationFields();

detailTable.ParentTableRelation.Add(relationFields_Skucode);

relationFields_Skucode.MasterKeyField = "prodSkucode";

relationFields_Skucode.DetailKeyField = "prodSkucode";

radGriOrdComDetalles.MasterTableView.DetailTables.Add(detailTable);

detailTable.Name = "tabDetail" + IdOrdenCompra + Skucode;

detailTable.DataKeyNames = new string[] {"prodSkucode" };

detailTable.EnableViewState = true;

detailTable.NoDetailRecordsText = "";

detailTable.Caption = "Detalle del producto Sku " + Skucode;

detailTable.EditMode = Telerik.Web.UI.GridEditMode.InPlace;

foreach (DataColumn dc in datTabDatosDetalle.Columns)

{

Telerik.Web.UI.GridBoundColumn campo = new Telerik.Web.UI.GridBoundColumn();

detailTable.Columns.Add(campo);

campo.UniqueName = "col" + dc.ColumnName;

campo.HeaderText = "[ " + dc.ColumnName + " ]";

campo.HeaderStyle.Font.Bold = true;

campo.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

campo.DataField = dc.ColumnName;

if (dc.ColumnName == "Id")

{

campo.Visible = false;

}

if (dc.ColumnName == "prodSkucode")

{

campo.Visible = false;

}

if (dc.ColumnName == "Talla")

{

campo.ReadOnly = true;

}

Telerik.Web.UI.GridEditCommandColumn campoEdit = new Telerik.Web.UI.GridEditCommandColumn();

detailTable.Columns.Add(campoEdit);

campoEdit.UniqueName = "colEdit";

campoEdit.ButtonType = Telerik.Web.UI.GridButtonColumnType.LinkButton;

campoEdit.EditText = "Editar";

campoEdit.UpdateText = "Actualizar";

campoEdit.CancelText = "Cancelar";

detailTable.DataSource = datTabDatosDetalle;

detailTable.Rebind();

radGriOrdComDetalles.Rebind();

How to create context menu dynamically on client side

Hi,

I want to create context menus on client side dynamically, does telerik context menu support this?

As I know, we can use

var _menu = $find('<%=Menu.ClientID%>');

to retrieve a context menu, this means we have to add a context menu at design time in html or create one at server side runtime, but how we can create a context menu in client side?

I need to create context menus on client side, how I can reach this?

Thanks.

Restartable Uploads

Hi,

I have a web application in which I am currently using Microsoft's standard upload control. However, users are having problems with uploads not completing when they try it from locations with poor connectivity.

Questions:

1. Could your upload control improve the situation?

2. Can your upload be restarted, i.e., if a timeout occurs does it save what was already received so that it can pick up from where it left off?

3. Are there IIS changes that you recommend to better handle upload processing?

Thank you

Upload (Obsolete)
