Hi,

We are trying to do something like Telerik online purchase check out list where user could update the quality by using combobox and also delete product as they wish.

We only manage to bind the session to the Grid, but, we are not able to bind the delete command and also the edit to the Grid item. The RadGrid1_ItemDeleted will never been fired.

Please advice.

    
            Dim objDT As System.Data.DataTable 
        
            Dim objDR As System.Data.DataRow 
        
            Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource 
        
            objDT = Session("Cart") 
        
            RadGrid1.DataSource = objDT 
        
            End Sub 
        
            Protected Sub RadGrid1_ItemDeleted(ByVal source As Object, ByVal e As Telerik.Web.UI.GridDeletedEventArgs) Handles RadGrid1.ItemDeleted 
        
            ' Some code to delete 
        
            End Sub 
        
            Private Sub makeCart() 
        
            If IsNothing(Session("Cart"))Then 
        
            objDT = New System.Data.DataTable("Cart") 
        
            objDT.Columns.Add("ID", GetType(Integer))

[Solved] Force fastNavigationPopup to close

I got a little problem with a SharedCalendar. The problem is when i open the fastNavigationPopup and use the fastnavigation arrow while the popup is opened if a select a date after(without closing the popup) it give me a javascript error with the following code

this.RadCalendar._serializeSelectedDates();

To prevent that i'm trying to get the fastNavigationPopup (_getFastNavigation()) and close it just before i click somewhere else in the calendar. Is there anyway to close it???

Thank you!

RadNumericTextBox Allowing Decimals

Hello,

I'm trying to prevent numbers like:

500.10

I want only amounts like:

500

entered.

I setup the RadNumericTextbox with:

DecimalDigits="0"
DataType="System.Int32"
MinValue="0"

And even though I have this, it still allows 500.10. Also, ValueChanged seems to fire after the RadNumericTextBox adjusts the value to 500. So User enters 500.10, the ValueChanged client-side event fires, and the value is adjusted to 500 in RadNumericTextBox.

Is there a way to get the value to adjust before this event fires, or is there a better event to tap into?

Thanks.

Access FormTemplate controls from javascript when using UpdatePanel

Hi,
I am using grid with FormTemplate popup for edit or update row and i need to access the FormTemplate controls from javascript code.
I found a way to do that using he forums and documetations and it is working good. the problem is when i add update panel to my page in order to avoid postbacks, i get nulls while accessing my controls on javascript.

This is how i implement finding the controls:

in the code behind:

    
              protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) 
        
                    { 
        
                        if (e.Item is GridEditFormItem && e.Item.IsInEditMode) 
        
                        { 
        
                            GridEditFormItem editFormItem = (GridEditFormItem) e.Item; 
        
                            RadComboBox cmbRoles = editFormItem.FindControl("RoleCombo") as RadComboBox; 
        
                            if (cmbRoles != null) 
        
                            { 
        
                                usersGrid.Controls.Add( 
        
                                    new LiteralControl("<script type='text/javascript'>window['RolesComboId'] = '" + 
        
                                                       cmbRoles.ClientID + 
        
                                                       "';</script>")); 
        
                            }               
        
                    }

and on javascript:

    
            function SetRoleVisibility(item) {           
        
                        var cmbRoles = $find(window['RolesComboId']);  
        
                    }

When the SetRoleVisibility is fired cmbRoles should hold the RadComboBox. it does when not using update panel, but once i use one, the $find method returns null.

Can you please advice?

Thanks,
Ruth

Problem with RadWindow Overlay

Hello,

I'm having a problem with the RadWindow and I.E 7. I have a RadGrid with a column that has a link to launch a modal window and display an edit form of the relevant data. The RadWindow is set to modal and the RadWindow displays fine with the overlay. However, if the size of the browser is wider than the width of the RadGrid content, the RadWindow displays but the RadGrid disappears - this is the only content on the page that disappears. if the width of the browser window is just a touch smaller than the width of the grid - the RadGrid remains visible. This problem is on I.E only and doesn't affect FireFox or Chrome browsers.

Thanks.

Jon

Removing/ Not Displaying/ Disabling the Expand/Collapse button on the Group Headers

I apologize if this was previously inquired. If so, please redirect me to the link accordingly. But as far as I have looked online, I still can't find the answer to this. I'm new to using the RadGrid control and was wondering if there is a property I can set that will not show the Expand/Collapse button on the RadGrid's group headers. If there is Javascript code for this, that will work as well but if this can only be done by server-side code (preferably C#), please let me know as well. Thanks!

Static Headers in Grid

While using StaticHeaders in Rad Grid, for scrolling option, the header of each column is not aligned properly with the grid items. The alignment is proper while not using StaticHeaders. Is there any solution for this?
