How to disable previous date in Rad Date Picker

if you want to disable the Previous date selection, you may use SelectableDateStart property of RadDatePicker.
Here is a sample code:

txtStartDate.SelectableDateStart = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);
txtEndDate.SelectableDateStart = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);

Or

// txtStartDate.SelectableDateStart = DateTime.Today;

//txtEndDate.SelectableDateStart = DateTime.Today;

Client Side

Load RadGridView

 

public void bindCallFoward()
{
//this is show busy icon
this.rbiActivity.IsBusy = true;

//we use service to get record you use which way to access data
ServiceManager manager = ServiceManager.GetServiceManager();
SetMyLeadsWebServiceSoapClient ServiceClient = manager.ServiceClient;
ServiceClient.GetCallForwardcompanyNumberCompleted +=new EventHandler<GetCallForwardcompanyNumberCompletedEventArgs>(ServiceClient_GetCallForwardcompanyNumberCompleted);
ServiceClient.GetCallForwardcompanyNumberAsync(CompanyId, manager.User.Login, manager.User.Password);
}

void ServiceClient_GetCallForwardcompanyNumberCompleted(object sender, GetCallForwardcompanyNumberCompletedEventArgs e)
{
if (e.Error == null)
{

if (e.Result != null && e.Result.Count() > 0)
{

rgdCallForwerding.ItemsSource = e.Result;

}
else
{

rgdCallForwerding.ItemsSource = null;
}

this.rbiActivity.IsBusy = false;
}

}

which check if fowerdnumber cell empty then save button show disable

private void rgdCallForwerding_RowLoaded(object sender, RowLoadedEventArgs e)
{
if (e.Row.DataContext != null)
{
callinnumber cbf = e.Row.DataContext as callinnumber;
var button = e.Row.ChildrenOfType<RadButton>().Where(b => b.Name == “btnSave”).FirstOrDefault();

if (cbf.FowardNumber.Length<=0)
{

button.IsEnabled = false;

}
else
{
button.IsEnabled = true;

}

}
}

 

private void rgdCallForwerding_RowEditEnded(object sender, GridViewRowEditEndedEventArgs e)
{

}

// if you click on empty Call forwerd Cell then enable Save button

I have a RadGridView in which one of the columns contains only buttons.

Depending on the value of a boolean variable linked to a specific record in the grid, I enable or disable the cell containing the button. This is how I achieve this:

private void rgdCallForwerding_SelectionChanged(object sender, SelectionChangeEventArgs e)
{
foreach (callinnumber items in rgdCallForwerding.SelectedItems)
{
//if (rgdCallForwerding.Items.IsEditingItem)
//        {
var    row = this.rgdCallForwerding.ItemContainerGenerator.ContainerFromItem(items) as GridViewRow;

if (row != null)
{

var button = row.FindChildByType<RadButton>();

button.IsEnabled = true;

//var cell = (from c in row.Cells
//            where c.Column.UniqueName == “btnSave”
//         select c).FirstOrDefault();
// if (cell != null)
// {
//     if (items.FowardNumber.Length<=0)
//     {
//         cell.IsEnabled = true;
//     }
//     else
//     {
//         cell.IsEnabled = false;
//     }
// }
}

}

}

 

 

// Save

void btnSave_Click(object sender, RoutedEventArgs e)
{
string _CompanyNumber = “”;
RadButton btnSave = sender as RadButton;
if (btnSave != null)
{

_CompanyNumber = (string)btnSave.CommandParameter;

foreach (callinnumber item in rgdCallForwerding.SelectedItems)
{

Regex regex = new Regex(“^[0-9]*$”);
if (regex.IsMatch(item.FowardNumber))
{
//    if (item.FowardNumber != string.Empty)
//{
if (rgdCallForwerding.Items.IsEditingItem)
{
int _forwardid = item.forwardid;
string _Number = _CompanyNumber;
string _FowardNumber = item.FowardNumber;
int _Companyid = item.Companyid;
ServiceManager manager = ServiceManager.GetServiceManager();
SetMyLeadsWebServiceSoapClient ServiceClient = manager.ServiceClient;
ServiceClient.SaveCallforwardCompleted += new EventHandler<SaveCallforwardCompletedEventArgs>(ServiceClient_SaveCallforwardCompleted);
ServiceClient.SaveCallforwardAsync(_forwardid, _Number, _FowardNumber, _Companyid, manager.User.Login, manager.User.Password);
break;

}

//}
//else
//{
//    MessageBox.Show(“Empty not allowed to Save”);

//}

}
else
{
MessageBox.Show(“Only numbers may be entered here”);

}

}
}

}

private void ServiceClient_SaveCallforwardCompleted(object sender, SaveCallforwardCompletedEventArgs e)
{
if (e.Error == null)
{

MessageBox.Show(“CallFoward Save Successfully.”);

}
bindCallFoward();
