im wanting to open a radwindow from a hyperlink in a grid. the window provides a way to update the row item, so populates a form within a window with the existing field values.

previously it was being done on rowclick so just worked with loading the fields from the GridDataItem and opening the window via

Me.pBlocks.VisibleOnPageLoad = True

this now needs to be done via a hyperlink on one of the columns.

the hyperlink column is added in the code behind

hlc =

New GridHyperLinkColumn

Me.uxBlocks.Columns.Add(hlc)

hlc.HeaderText = GetCaption(p.Name)

hlc.UniqueName = p.Name

hlc.DataTextField = p.Name

hlc.DataNavigateUrlFields = {p.Name}

hlc.DataNavigateUrlFormatString =

"linktowindow?q={0}"

hlc.Display = True

hlc.HeaderStyle.Width =

Unit.Pixel(170)

hlc.ItemStyle.Wrap =

True

could i still call the existing method by getting the GridDataItem when the link is clicked?

Access RadComboBox from GridTemplateColumn

I can't seem to figure out how to get the selected value or text from a RadComboBox in a GridTemplateColumn. Actually seems like I can't find the control at all. The edit Form is a popup. The grid is in a user control.

Here is my column

<telerik:GridTemplateColumn UniqueName="ProdWorkstation" HeaderText="ProdWorkstation">

<ItemTemplate>

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

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="RadComboBox_SelectWorkStation" Height="300px" Width="750px" DataSourceID="LCM_UserWorkstationList" EnableLoadOnDemand="true"

ItemsPerRequest="20" EnableAutomaticLoadOnDemand="False" DataTextField="Workstation" DataValueField="Workstation"

style="margin-bottom: 0px" AutoPostBack="True" HighlightTemplatedItems="true" CausesValidation="False" Skin="Office2007"

OnItemsRequested="RadComboBox1_ItemsRequested">

<HeaderTemplate>

<ul>

<li class="col75">user_id</li>

<li class="col200">Workstation</li>

<li class="col200">Name</li>

<li class="col200">Profile</li>

</ul>

</HeaderTemplate>

<ItemTemplate>

<ul>

<li class="col75"><%# DataBinder.Eval(Container.DataItem, "user_id")%></li>

<li class="col200"><%# DataBinder.Eval(Container.DataItem, "Workstation")%></li>

<li class="col200"><%# DataBinder.Eval(Container.DataItem, "Name") %></li>

<li class="col200"><%# DataBinder.Eval(Container.DataItem, "Profile")%></li>

</ul>

</ItemTemplate>

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Here is the codebehind where I try and get the text:

if (e.CommandName == "PerformInsert")

{

GridEditFormInsertItem EditForm = (GridEditFormInsertItem)e.Item;

RadComboBox combo = EditForm["ProdWorkstation"].Controls[0] as RadComboBox;

string ProdWorkstation = combo.Text; //NULL value

How can I do this?

Thanks!

MinutesPerRow not well refreshed

Hello,

I would like to allow the users to select the number of minutes per row of the Scheduler themselves.

I'm trying to reproduce a small part of the Scheduler customization demo page available there:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/customization/defaultcs.aspx

In my very simple example, I only have a drop down list to select the number of minutes and a Scheduler component with no datasource.

Page:

    
                    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" /> 
        
                    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                        <AjaxSettings> 
        
                            <telerik:AjaxSetting AjaxControlID="Panel1">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="Panel1" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
                    </telerik:RadAjaxManager> 
        
                    <telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" /> 
        
                    <asp:Panel runat="Server" ID="Panel1">  
        
                            Minutes per row:   
        
                            <asp:DropDownList runat="server" ID="MinutesPerRow" AutoPostBack="true">  
        
                                <asp:ListItem Value="60" Text="60"></asp:ListItem> 
        
                                <asp:ListItem Value="30" Text="30" Selected="true"></asp:ListItem> 
        
                                <asp:ListItem Value="15" Text="15"></asp:ListItem> 
        
                                <asp:ListItem Value="10" Text="10"></asp:ListItem> 
        
                            </asp:DropDownList> 
        
                        <telerik:RadScheduler runat="server" ID="RadScheduler1"   
        
                             ShowFullTime="true" OverflowBehavior="Expand" 
        
                             DataKeyField="ID" DataStartField="Start" DataEndField="End" DataSubjectField="Subject" >                 
        
                        </telerik:RadScheduler>

Code behind:

    
                protected override void OnPreRender(EventArgs e)  
        
                {  
        
                    base.OnPreRender(e);  
        
                    RadScheduler1.MinutesPerRow = int.Parse(MinutesPerRow.SelectedValue);  
        
                }

This example completely failed.
When I select a value in the drop down list the Panel is refreshing but the Scheduler is still displaying the previous selected value.
I have to do a second post back to obtain the correct layout.

Did I forget something?

Thank you for you help.

can the suggestion tool learn or be improved?

Hi,

I am just trying RadSpell for the first time. So far, I am rather un-impressed by the suggestions that the spellchecker makes.

A basic example is 'teh'. Everyone knows that this is a typo for 'the'. Every spellchecker in the land will suggest 'the' as the best replacement. With RadSpell, 'the' comes up at around TENTH in the list. The top suggestion is 'tea'.

This is not going to cut it for our end-users. Is there a way to improve the suggestion tool so that it is more like other spell-checkers? Or can the tool at least learn from what words have been changed to by other users?

Thanks,

Craig

Passing Values from a "RadGrid" to a "Filtering Template Column"

I'm using the example provided in Filtering Template Columns to use a RadComboBox as a filter instead of the standard TextBox. I have followed the example and it is working as expected. Now I need to know how to pass a value to the RadComboBox so I can dynamically change its DataSource. The DataSource for the RadComboBox should change depending on the value of a column in the RadGrid. Can I somehow access the DataKeyNames of the parent RadGrid to get this value or is there a property of the GridTemplateColumn that I can set in my code-behind? I'm stumped.

protected override void SetupFilterControls(TableCell cell)

{

RadComboBox rcBox = new RadComboBox();

rcBox.ID = this.GetType().Name + "ComboBox";

rcBox.AutoPostBack = true;

rcBox.DataTextField = this.DataField;

rcBox.DataValueField = this.DataField;

rcBox.SelectedIndexChanged += rcBox_SelectedIndexChanged;

rcBox.Items.Add(new RadComboBoxItem("Show All", ""));

rcBox.DataSource = DataSource; //<-------- I need to change this DataSource depending on what data is in my RadGrid.

//How can I pass a value here from my aspx page

rcBox.AppendDataBoundItems = true;
