I am using a RadGrid with a UserControl as my EditForm. I am doing some complicated custom validation when the ItemCommand is called on Update (e.CommandName = "Update") when a btn is clicked in the UserControl. I cannot use regular validation via one of the standard .net validation controls. My problem is that when my custom validation process is complete after the btn is clicked, I do not know how to keep the RadGrid in Edit mode with the UserControl / EditForm still exposed. I want to essentially keep the UserControl with the user's initial edits open with instructions for the custom validation, while being able to postback to do server validation.

How do I return to Edit mode within the ItemCommand event for CommandName == "Update"?

I have an ASP .NET 2.0 application using standard asp controls. My project is to replace the asp controls with Telerik controls. We have versions from 2007 to 2012, which version would be the best to use for the update project?

Thanks,

Unable to set RadEditor Default font size

So far as I know I've been following your documentation to the letter. (http://www.telerik.com/help/aspnet-ajax/editor-default-font-for-editable-content.html etc...)

I have a RadEditor with the necessary EditContentArea.css.

In the css I have:
body {
background-color: white;
font-family: Arial !important;
font-size: 10pt !important;
}

But no matter what I do, the editor always comes up in Times-Roman 16pt.

What could I be missing?

Persisting Grid Settings - Save on Column Show/Hide

I have a RadGrid that has several columns. (18 to be precise) though only 6 of these columns display by default. The rest are set to 'display=false'. I'm trying to make it show that when a user changes what columns are displayed that change is persisted through their experience using sessions so that if they navigate away and come back to the page it will retain the changes they made.

I am following the instructions provided: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/savinggridsettingsonperuserbasis/defaultcs.aspx on the demo however I am having issues with modifying this so that it calls my SaveSettings method.

Is there a way to have it so that when the user hides or shows a column that it calls the SaveSettings method?

GridInsertionObject error on hierarchy grid on expand of child grid

I have a hierarchy radgrid that contains "Case Number" parent objects and "Offense" child objects and supports Insert/Update/Delete functionality.

I am getting the following error:

DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'AgencyID'.

To get this error I am performing the following actions:

Click the "Add New Case Number" button (the Case Number form template is displayed)
Fill in the required Case Number fields and click the insert button (upon doing this the "Add New Offense" button is displayed under the Case Number just inserted into the grid)
Click the "Add New Offense" button (the Offense form template is displayed)
Click the expand/collapse button next to the Case Number to collapse the Offense form template
Click the expand/collapse button next to the Case Number to expand the Offense form template

The error occurs at this point!

My question is how do I go about fixing this problem?

I am already supressing a similar binding error in the ItemCommand event handler in the case where an insert is initiated into the "Offenses" detail table that is empty.

I was trying to do something similar in the case of an ExpandCollapse command but had no luck.

Month/Year RadDatePicker inside of EditForm

I'm trying to use a raddatepicker in a radgrid where the user can only select the Month and Year, rather than the date from the RadCalendar.

I have implemented this once before using the javascript from the Code Library at the link below and it has worked fine.

http://www.telerik.com/community/code-library/aspnet-ajax/calendar/month-year-picker.aspx

Now I am trying to apply it to a raddatepicker that is inside of an EditForm and it will not work.

I can pass in the RadDatePicker's client ID and when I debug I see that it finds the object, but it continually tells me that the object does not contain those methods or properties.

The applicable code is below. Please let me know if you can help me or if you need any further information.

    
            <script type="text/javascript">  
        
                    //override the onload event handler to change the picker after the page is loaded

How would I validate checked for a radbutton with ToggleType="CheckBox"

I have one checkbox( ToggleType="CheckBox") and then a regular radbutton(ButtonType="StandardButton") to proceed.

I am using this for "Accept Terms"

Radgrid OnCommand client side makes e.Item.ItemIndex 0

Hi,

I've pasted my code below. I need to know which row caused the itemcommand server side. This works fine in below code as long as the OnCommand client event is not used. When i start using it the ItemIndex is always 0. The same issue is described in http://www.telerik.com/community/forums/aspnet-ajax/grid/itemcommand-why-is-my-itemindex-always-zero.aspx, but the solution does not work for me as the selected row might be different. GetDataKeyValue also does not work it always returns the data key from first row.

Is there a way to find which row caused the itemcommand while have the client side OnCommand?

Thanks!

using System;

using Telerik.Web.UI;

public partial class Default : System.Web.UI.Page

{

public class A

{

public int a { get; set; }

public int b { get; set; }

}

protected void Page_Load(object sender, EventArgs e)

{

RadGrid1.DataSource = new A[] {new A() {a = 1, b = 2}, new A() {a = 3, b = 4}};

}

protected void rg_ItemCommand(object sender, GridCommandEventArgs e)

{

int i = e.Item.ItemIndex;

GridDataItem item = (GridDataItem)e.Item;

int letterId = (int)item.GetDataKeyValue("a");

//GridDataItem dataItem = RadGrid1.SelectedItems[0] as GridDataItem;

RadPanelItem.DataItem is null on DataBind within FormView

I have a FormView hooked into an ObjectDataSource. Inside the FormView sits a RadPanelBar. I have some databound controls within the RadPanelBar and I've had a terrible time getting them to work.

First, I used the suggested method, DataBinder.Eval(FormView1.DataItem, "BillingDate"). This causes the FormView to have an empty oldValues and newValues collection when it updates. That took me days to figure out.

I then tried an alternative method, strongly typing the DataItem from the container.

((Wcsr.ProjectBilling.Business.Data.ProjectTask)

(Container.DataItem ?? new Wcsr.ProjectBilling.Business.Data.ProjectTask())).Code

I am getting a null DataItem here. If I use FormView1.DataItem, the oldValues and newValues collections become empty again. What can I do?

<asp:FormView ID="FormView1" runat="server" DataSourceID="ObjectDataSource1" DefaultMode="Edit" OnItemUpdated="FormView1_ItemUpdated" OnItemUpdating="FormView1_ItemUpdating">
