Questions on UI for ASP.NET AJAX Forum

1. I have Dropdown controls that get styled with the decorator. When the user clicks on the down button, the dropdown list expands, but then clicking the button again will not contract the list. This is breaking the correct operation of the dropdownlist.

<asp:DropDownList ID="AddressDropDownList" runat="server" DataSourceID="AddressSqlDataSource" DataTextField="adrFullname" DataValueField="adrIdx" AppendDataBoundItems="True" AutoPostBack="True">

<asp:ListItem Value="" Text="--All--"></asp:ListItem>

</asp:DropDownList>

2. The styling doesn't match a RadCombo on the same form. The RadCombo has the text box area shaded, the dropdownlist doesn't. Makes it pretty obvious where one or the other was used and provides inconsistent UI. Is there a way to get them to match?

<telerik:RadComboBox ID="xrcarCarIdxRadComboBox" runat="server" DataSourceID="CarrierListSQLDataSource" DataTextField="carName"

DataValueField="carIdx" SelectedValue='<%# Bind("xrcarCarIdx") %>' Width="300" HighlightTemplatedItems="true">

<ItemTemplate>

<asp:Label runat="server" ID="CarrierListLabel" >

<b><%# Eval("carName") %></b><br /><%# Eval("carAddress")%><br /><%# Eval("carCSZ")%>

</asp:Label>

</ItemTemplate>

</telerik:RadComboBox>

In the master page:

<telerik:RadFormDecorator ID="FormDecorator1" runat="server" DecoratedControls="all" >

</telerik:RadFormDecorator>

No property or field 'ParentID' exists in type 'DataRowView' In Self Referencing Heirarchy

Hi,
I am trying to get a Datagrid to work using Self Referencing heirarchy, but I get the error: No property or field 'ParentID' exists in type 'DataRowView' when I add the FilterExpression:

RadGrid1.MasterTableView.FilterExpression =

"ParentID is null "

The code is modeled after the sample here

I can get it to work without the FilterExpression, but all items show up under the main grid, and then again as children. It seems very simple, but I must be missing something.

Cannot access cell value in ItemDataBound

Hello, I´m using a RadGrid for displaying data bound using the "NeedDataSource"-event. It works almost perfectly. Since I want a combobox in one of the columns, i have a GridTemplateColumn which looks like this:

<telerik:GridBoundColumn DataField="CommunicationModule" HeaderText="CommunicationModule" UniqueName="CommunicationModule" ></telerik:GridBoundColumn>

<telerik:GridTemplateColumn DataField="Module" HeaderText="Module" UniqueName="Module" ItemStyle-Width="400px">

<ItemTemplate>

<%#DataBinder.Eval(Container.DataItem, "Module")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="cboModule">

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

The first column holds the database value (int) and the second column contains the combobox. My plan is to use the first column (which in the end is supposed to be hidden) to set the SelectedValue of the combobox.

I´m using the ItemDataBound event to detect when to populate the combobox and set the selected item. The problem is that every time I try to access the cell value of the "CommunicationModule" cell, it contains &nbsp. I try to do this using the e.item["CommunicationModule"].Text.

Since I populate the grid using entity framework and a anonymous list created by a query, I cannot directly cast the e.Item.DataItem either. In that case I need to create a helper class that matches the signatures of my query and that would create much more work for me since I´m doing several pages with grids populated with different data. The Grid is in "EditForms" Editmode

So:

protected void RadGridCU_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.IsInEditMode)

{

if (!(e.Item is IGridInsertItem)) //Is this a new item?

{

GridEditFormItem item = (GridEditFormItem)e.Item;

RadComboBox cmb = (RadComboBox)item.FindControl("cboModule");

cmb.DataSource = //Here I have logic to set the datasource (works);

cmb.DataTextField = "Name";

cmb.DataValueField = "OID";

//I tried to use

//item["CommunicationModule"].Text.ToString();

//But to get it to work, I needed to create helper class and then cast the dataitem..

cmb.SelectedValue = ((MyGridHelperClass)e.Item.DataItem).CommunicationModule.ToString();

cmb.DataBind();

}

How can I really access the cell value without the need of accessing the DataItem?

When using EditForms, I can access the value using
item.ParentItem["CommunicationModule"].Text.ToString();

But when using InForms edit, I cannot access the value using item["CommunicationModule"].Text.ToString().

RadEditor page properties dialog background image upload

Hello !

I am using Page Properties dialog in order to set background color or background image of RadEditor window. What I have noticed is there is not any control for uploading background image from local computer. We can just specify path of directory where images are exists on server using ImageManager's ViewPaths property. Is there any solution if I want to upload the image from local computer and set it as background image?

Awaiting for your valuable response.

Thanks

PostbackTrigger control in another usercontrol (LOD)

I have a RadAsyncUpload control in one usercontrol, loaded dynamically (wizard-style using RadTabStrip and RadMultiPage). I don't want to trigger the FileUploaded event until the Save button is clicked in the last panel of the wizard. Is this scenario supported? There will be a button in each PageView that will share the same ID--not a problem given that they are in different naming containers, of course, but perhaps a problem for RadAsyncUpload? How does it resolve the Control IDs contained in the PostbackTriggers property?

Thanks in advance for your help,

Larkin

How to force 12 hour clock

Is there a property to force a 12 hour clock for the RadScheduler... when I select the times for the event from the Start Time and End Time dropdowns it displays 24 hour clock times. I'd like this to be 12 hour clock only.

Wrong rendering with Doctype 4.0

Hi,

I'm using the RadSplitter together with RadSlidingPanes in a rather big project.
Everything worked fine (with version 2012.1.215.35) until recently in IE 10. In IE10/Win 8 the panes would not move.

I've upgraded to version 2012.3.1205.35 and the panes are working again, but there's a rendering error (also in IE9). When I open and close a pane, the pane displays on the bottom of the screen.

I've tested this with the demo found here: http://demos.telerik.com/aspnet-ajax/splitter/examples/sp_firstlook/defaultcs.aspx

The problem is our DocType. In our project we must use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

I know everything works fine with Doctype 4.01, but I can't use this for now in this project.

Is there any workaround or a fix?

Thanks in advance!
