I've been tasked with writing a scheduler for football pitches. Each pitch can also be divided into two half pitches. Obviously if a half pitch is booked then the full pitch cannot be booked at the same time and I need to add a 15 minute interval between every booking. So if a half pitch is booked for 2pm the full pitch cannot be booked until 3.15pm (1 hour + 15 minutes). However, someone could book the other half for 2.15pm which means the full pitch would not be available until 3.30pm (2.15 + 1 hour + 15 minutes). I have tried to do this using resources but I cannot work out how to create a resource (pitch) which could be 1st half or 2nd half or full depending on the other bookings (appointments) around it.
Any help / ideas / pointers would be very much appreciated.
Thank you!
Hi,
I've got an issue where the RadGrid is hiding columns that it shouldn't do when Google Chrome has hardware acceleration disabled. We're not seeing the same behaviour on Edge or Internet Explorer, and it doesn't seem to happen every time.
I'm trying to work around it in JavaScript by raising RadAjaxManager.ajaxRequestWithTarget and raising the scroll event, but this just duplicates columns.
Can you give me a bit of guidance how to work round this?
Thanks

I have this Rad Grid setup

The Radgrid works fine to display the data. The problem is I cannot add, delete or edit any records. If I click the delete button or edit icon nothing happens. If I click the Add new comparison link all of the controls used to add a new record are displayed. The drop down list shows the first record for the list, but I cannot get the drop down list to open and show other selections, I cannot click into the text box to add new text.
But for some reason I can select a date for the date picker. If I click the Insert or cancel links nothing happens. What have I done wrong with this setup.
I am using a SQL Server view as my datasource for this grid. I have used views in the past without this problem.
Hello, have good time
I have a page where it's a grid.
In this grid one of the columns is hidden where the user ID is and in the other column it fills the user name with another table in the event ItemDataBound
But when grouping it shows the user ID while I need the name to show it.
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)// to access a row
{
GridDataItem item = (GridDataItem)e.Item;
if (RadGrid1.GroupingEnabled)
{
item["UserFLName"].Text = LstUser.FindAll(x => x.User_ID_ == int.Parse(item["User_ID"].Text))[0].User_FName + " " + LstUser.FindAll(x => x.User_ID_ == int.Parse(item["User_ID"].Text))[0].User_LName;
}
}

<telerik:RadToolBar runat="server" Width="100%" ID="RadToolBar1" EnableRoundedCorners="true" OnClientButtonClicked="javascript:if(!PageValidation()){return false;}" OnButtonClick="RadToolBar1_ButtonClick" EnableShadows="true" Skin="Office2007" Height="27px" AutoPostBack="false"> <Items> <telerik:RadToolBarButton Text="Export" Value="1" PostBack="true" /> <telerik:RadToolBarButton IsSeparator="true" />function PageValidation() { var IsValid = false;
var error = document.getElementById("errorMsg"); var mastertableView = $find("<%= RadGrid1.MasterTableView.ClientID %>"); var count = mastertableView.get_selectedItems().length; if (count < 1) {
error.style.display = "inherit"; IsValid = false; } else {
error.style.display = "none"; IsValid = true; } return IsValid; }OnClientButtonClicked="PageValidation" ", the client side validation works with the error msg pop up but it cannot stop the post back. Hello Guys
