Hi,

 I have a RadWindow which opens up on the click event of a rad button present in each row of a RadGrid.

The RadWindow doesn't open on the single click for the first time (it takes double click for the first time) and opens in single click the next time.

Please see the code below and not sure if I am missing some thing.

Thanks!

ASPX:

<telerik:GridTemplateColumn HeaderText="Order Now" AllowFiltering="false" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="10%" ItemStyle-Width="10%">
                            <ItemTemplate>
                                <asp:LinkButton ID="gvlnkbtnViewMenu" runat="server" Text="View" CommandName="VIEW" CausesValidation="false" ToolTip="Open PDF" ForeColor="#B72B3C" Font-Bold="false" Font-Underline="true"></asp:LinkButton>
                            </ItemTemplate>

</telerik:GridTemplateColumn>​

  <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
            <Windows>
               <telerik:RadWindow ID="UserListDialog" runat="server" Modal="true" OnClientShow="setWindowsize" VisibleStatusbar="false" Title="" >
                </telerik:RadWindow>
            </Windows>
        </telerik:RadWindowManager>

 function ShowEditForm(id, rowIndex) {
                var grid = $find("<%= radGridPrintStatus.ClientID %>");
                    var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
                    grid.get_masterTableView().selectItem(rowControl, true);
                    window.radopen("Viewer.aspx?ID=" + id, "UserListDialog");
                    return false;
             }

ASPX.CS :

 protected void radGridPrintStatus_ItemCommand(object sender, GridCommandEventArgs e)
        {
            if (e.CommandName.ToUpper().Equals("VIEW"))
            {
                GridDataItem item = (GridDataItem)e.Item;
                string rowId = item["MenuId"].Text;
                LinkButton editLink = (LinkButton)item.FindControl("gvlnkbtnViewMenu");
                editLink.Attributes["href"] = "javascript:void(0);";
                editLink.Attributes["onclick"] = String.Format("return ShowEditForm('{0}','{1}');", rowId, e.Item.ItemIndex);              
            }

I have some cascading comboboxes.  No matter where I am when I start, when I select the first and the other is updated, the 1st keeps focus, but the page scrolls up so that the ​1st control is at the very bottom of the browser window.  What can I do to change this?

 

The autocomplete box is rendered in a div element, other controls just in a span. ​If I ​assign a label to a Telerik control, the control is placed right of the label, but the auto complete box is placed underneath (as it's a div, not just a span).

 

Can I somehow change that behavior?

On my radgrid, I have EditFormSettings EditFormType set to WebUserControl.  Inside that WebuserControl, I have a submit button and a delete button.  And I know that you can close these by setting the CommandName to Update or Cancel.  However, this is not working when I have the another control nested inside that control. 

Can I close these windows explicitly either through js or the codebehind?  I'm not sure but I think my problem is that I have a control nested inside another control. Both have the commandnames set to Update and Cancel.  There must be some conflict?

Thanks in advance.

In the ListBox ItemTemplate Demo, a numeric textbox is included to allow users to enter order Quantity. No problem creating a similar item template. No problem passing item.Value to SqlParameter and inserting to database. But I cannot figure out how to grab a value from a textbox and pass that as another parameter.

Code below passed an empty string or NULL to @Quantity: 

 

 foreach (RadListBoxItem item in collection)
                {
                    cmd4.Parameters.Clear();
                    cmd4.Parameters.AddWithValue("@Product_ID", item.Value);
                    cmd4.Parameters.AddWithValue("@Quantity", Convert.ToInt32(item.FindControl("RadNumericTextBox1.Text") as TextBox));
                    cmd4.ExecuteNonQuery();
                }​

A few articles I found suggest textbox values are lost during postback? Anyone else run into this problem? Advice appreciated.

 

                              

1. How do I set RadDatePicker to ReadOnly mode so that it prints better (Enabled = False prints light).
2. How do I hide the calendar icon in ReadOnly mode?    RadComboBox has .ShowToggleImage = False but not RadDatePicker.
