HOW TO

Access controls in the advanced form


DESCRIPTION

RadScheduler's FormCreated event allows you to access elements on the advanced form. This is achieved using the FindControl method of e.Container and passing as an argument  the last part of the rendered  control's ID. For example, to access the advanced controls' panel, you need to use e.Container.FindControl("AdvancedControlsPanel")

scheduler advanced panel




The description labels Resources require a different approach since they are WebControls which dynamically add the label. For example, suppose you want to modify the description for the Room's resource:

label for the room resource



You still need to use the FindControl() method. However, e.Container.FindControl("LblResRoom") will return a WebControl. Once you get this WebControl you can clear its children and add a new label dynamically.  


SOLUTION

C#
protected void RadScheduler1_FormCreated(object sender, Telerik.Web.UI.SchedulerFormCreatedEventArgs e)  
{  
    if ((e.Container.Mode == SchedulerFormMode.AdvancedEdit) || (e.Container.Mode == SchedulerFormMode.AdvancedInsert))  
    {  
        //Find and hide the advanced control panel:     
        //Panel advancedPanel = (Panel)e.Container.FindControl("AdvancedControlsPanel");  
        //advancedPanel.Visible = false;     
 
        //Find the Subject textbox and set its Height:     
        RadTextBox subjectTextbox = (RadTextBox)e.Container.FindControl("Subject");  
        subjectTextbox.Height = Unit.Pixel(20);  
        subjectTextbox.Label = "Subject (modified):";  
 
        //Find the RadComboBox control for the Room resource and set its SelectedIndex property.      
        //This is useful if you want to default to a specific resource selection. However,     
        //you should leave only the AdvancedInsert clause from the if statement above.      
        //RadComboBox resRoomDDL = (RadComboBox)e.Container.FindControl("ResRoom");  
        //resRoomDDL.SelectedIndex = 2;  
 
        //Find the TextBox for the Description custom attribute and set its background color and label:     
        RadTextBox attrAnnotationsTextbox = (RadTextBox)e.Container.FindControl("AttrDescription");  
        attrAnnotationsTextbox.BackColor = System.Drawing.Color.Yellow;  
        attrAnnotationsTextbox.Label = "Description(modified): ";  
 
 
        //Change the description for the Room resource:     
        WebControl resWebcontrol1 = (WebControl)e.Container.FindControl("LblResRoom");  
        Label resLabel1 = new Label();  
        resLabel1.Text = "Room(modified):";  
        resWebcontrol1.Controls.Clear();  
        resWebcontrol1.Controls.Add(resLabel1);                         
    }   
} 

VB.NET
Protected Sub RadScheduler1_FormCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerFormCreatedEventArgs) Handles RadScheduler1.FormCreated  
 
        If (e.Container.Mode = SchedulerFormMode.AdvancedEdit) OrElse (e.Container.Mode = SchedulerFormMode.AdvancedInsert) Then 
            'Find and hide the advanced control panel:     
            'Dim advancedPanel As Panel = DirectCast(e.Container.FindControl("AdvancedControlsPanel"), Panel)  
            'advancedPanel.Visible = False  
 
            'Find the Subject textbox and set its Height:     
            Dim subjectTextbox As RadTextBox = DirectCast(e.Container.FindControl("Subject"), RadTextBox)  
            subjectTextbox.Height = Unit.Pixel(20)  
            subjectTextbox.Label = "Subject (modified):" 
 
            'Find the RadComboBox control for the Room resource and set its SelectedIndex property.      
            'This is useful if you want to default to a specific resource selection. However,     
            'you should leave only the AdvancedInsert clause from the if statement above.      
            Dim resRoomDDL As RadComboBox = DirectCast(e.Container.FindControl("ResRoom"), RadComboBox)  
            resRoomDDL.SelectedIndex = 2  
 
            'Find the TextBox for the Description custom attribute and set its background color and label:     
            Dim attrAnnotationsTextbox As RadTextBox = DirectCast(e.Container.FindControl("AttrDescription"), RadTextBox)  
            attrAnnotationsTextbox.BackColor = System.Drawing.Color.Yellow  
            attrAnnotationsTextbox.Label = "Description(modified):" 
 
            'Change the description for the Room resource:     
            Dim resWebcontrol1 As WebControl = DirectCast(e.Container.FindControl("LblResRoom"), WebControl)  
            Dim resLabel1 As New Label()  
            resLabel1.Text = "Room: (modified)" 
            resWebcontrol1.Controls.Clear()  
            resWebcontrol1.Controls.Add(resLabel1)  
        End If 
 
    End Sub
