Decided to make a new thread per http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-footer-validation.aspx

Using the ItemDataBound, everything is working except the e.Canceled = true; line. When the values don't match I get the response.write "Cancelled" message on my page as intended but the e.Canceled = true; line doesnt execute and the updates execute . And when they do match, update executes sucessfully and I dont get the message as intended.

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridFooterItem)

{

GridFooterItem fitem = (e.Item as GridFooterItem);

string value1 = fitem["CALENDAR_DAYS_MTD"].Text;

string value2 = fitem["WEEKENDS_MTD"].Text;

string value3 = fitem["HOLIDAYS_MTD"].Text;

string value4 = fitem["BUSINESS_DAYS_MTD"].Text;

int footervalue1;

int footervalue2;

int footervalue3;

int footervalue4;

int.TryParse(value1, out footervalue1);

int.TryParse(value2, out footervalue2);

int.TryParse(value3, out footervalue3);

int.TryParse(value4, out footervalue4);

//to get the value only.

if (footervalue2 + footervalue3 + footervalue4 != footervalue1)

{

e.Canceled = true; // Cancel Update

Response.Write("Cancelled");

}

Problem with DefaultButton in Q2 2012

Did this issue come back to life in Q2? After upgrading to Q2 the issue described here was noticed in my login page which contains two radTextboxes and a radButton placed within an asp panel (default button set to radButton). If you enter a user name then use tab to enter the password, hitting enter on your keyboard (while radTextbox has focus) does nothing. Only after hitting the enter button twice or using the mouse to click back to the first textbox makes the enter key work. I tried setting the EnableSingleInputRendering to false but this did nothing. If I replace the radTextbox with an asp textbox everything works as expected.

Client Side Validation After Exiting Each Cell

I have a spreadsheet-type grid using GridBoundColumn and InPlace edit and I want to do a client-side numeric validation after the user exits each cell. I am not able to use a GridNumericColumn because of issues described here. Is there some kind of OnCellExit event that I can use? Thanks.

Cascading DropDownList's in RadGridView EditForm

So I've been Googling this and have found various articles pertaining to it, but none of the solutions seem to work. The screen I'm working on has a grid view for vehicle listings. When a listing is edited, the user can edit the Vehicle Type, Manufacturer & Model.

When a user selects Vehicle Type, the Manufacturer DropDownList will rebind, when a user selects a Manufacturer, the Model DropDownList will rebind. Unfortunately, I keep getting this error: 'DropDownList2' has a SelectedValue which is invalid because it does not exist in the list of items.

Maybe I have the binding order mixed up. Here is my code:

<telerik:RadGrid ID="radVehicleListingGrid" runat="server" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True" CssClass="AdminGridView" DataSourceID="sdsVehicleListings" GridLines="None" Skin="">
