The RadTextbox accept only numbers and decimail. How to use this validation expression for only accept 2 digits after decimal point. Example: 12.12, 123.23, 1234.12, 12345.67 like this.
I tried 2 ways.
1. ^((?:[1-9]\d*)|(?:(?=[\d.]+)(?:[1-9]\d*|0).\d+))$ --> This expression working fine but i need to accept only two digits after the decimal point.
 public void Textbox1_OnTextChanged(object sender, EventArgs e)
{
if (Regex.IsMatch(Textbox1.Text, @"^((?:[1-9]\d*)|(?:(?=[\d.]+)(?:[1-9]\d*|0).\d+))$ "))
{
 CalculationSummary();
}
else
{
 RadAjaxManager1.Alert("Please enter only numerics.");
}
}
 

****or****

^(\d+)?+([\.]{1})?+([\d]{1,2})?$ --> This expression working good. It accepts only two digits after the decimal point. but i got error below condition.
 
public void Textbox1_OnTextChanged(object sender, EventArgs e)
{
if (Regex.IsMatch(Textbox1.Text, @"^(\d+)?+([\.]{1})?+([\d]{1,2})?$"))
{
 CalculationSummary();
}
else
{
 RadAjaxManager1.Alert("Please enter only numerics.");
}
}

Can anybody please let me know the possible solution. Thanke in advance.

Hello everyone,

This problem is killing me so I have to ask...

I have an external form that I am using pretty much just like the example shown here: Grid / Editing with External Form

Of course I have different fields. I have 3 dropdowns all of which have data items that are available/filtered by whats been selected in a previous control cascading.

So for example: Select DD1 -> DD2 fills -> Select DD2 -> DD3 fills.

Now if I am inserting something this works fine, but if I go straight to edit an item from the grid, then the values in the grid can't be found in the dropdowns. The dropdown controls can be found, but not the items as if they were not binding or firing the selectedValue_Changed event so that the list option values can get populated. However if I go to insert something first then try to edit anything it all works like it's supposed to.

I am using OpenAccessDataSource's for the dropdowns. they look something like this:



So on the grids side of things. When I do the DisplayEditForm(GridDataItem selectedItem).... which looks like so:


if I haven't displayed the external form before using insert for instance, it fails at PlaceHolder.FindControl("cmbMapNames"). Always.
It throws a need to create new object error... and I have checked to confirm that it's not the dropdown but the list item that it can't find.
 
Now after displaying the form via insert... even if I cancel and don't do the insert... just displaying it, when I come back to update or edit anything in the grid it works beautifully.

Someone please help before I throw my desktop out the window.

Thanks! :D

Currently it seems that the ASP.NET Validators only work in server mode when used in the RadAjaxManager, but they work in client and server mode when in an UpdatePanel.

We currently converting our from ASP.NET UpdatePanels and are wondering if we are missing something simple?  If not can we plan on client side validation in RadAjaxManager in the near future?

Thanks,
Chris

I am having difficulties getting the links to show up on the scheduler(See attached file).  I tried putting a scheduler on a page, just loading a few "Appointments" of the Telerik type, then binding them to the RadScheduler.  They are kind of appearing on the correct date, but they are VERY skinny...Not sure what I am doing wrong...Below is the code I used to create the Appointments.

thanks

mark

 List<Appointment> appointments = new List<Appointment>();

            Appointment app1 = new Appointment();
            app1.Subject = "Appt1";
            app1.Description = "App Desc";
            app1.Start = new DateTime(2012, 12, 17);
            app1.End = new DateTime(2012, 12, 17);
            app1.ID = 1;

            appointments.Add(app1);

            Appointment app2 = new Appointment();
            app2.Subject = "Appt2";
            app2.Description = "App Desc";
            app2.Start = new DateTime(2012, 12, 20);
            app2.End = new DateTime(2012, 12, 20);
            app2.ID = 2;


            appointments.Add(app2);

            RadScheduler1.DataSource = appointments;
            RadScheduler1.DataStartField = "Start";
            RadScheduler1.DataEndField = "End";
            RadScheduler1.DataSubjectField = "Subject";
            RadScheduler1.DataKeyField = "ID";
            RadScheduler1.DataBind();


Here is my markup for the RadScheduler...
<telerik:RadScheduler ID="RadScheduler1" runat="server" AppointmentStyleMode="Default" Height="600" SelectedView="MonthView" ItemType="Telerik.Web.UI.Appointment"></telerik:RadScheduler>

My controls are from Q1 of THIS year...License ran out so I can't upgrade...ugh...

HELP???

thanks

Hello,
I have a template column in grid and RadAsyncUpload control created in template's InstantiateIn method. I assign image file extensions to AllowedfileExtensions property.
_uploadControl = new RadAsyncUpload()                                     
   {                                           ID = Item.user_name + "_upload",
                                               TemporaryFolder = HostingEnvironment.MapPath(Static.Config.Paths.UploadsFolder),                                                AllowedFileExtensions = _allowedExtensions,
                                              TemporaryFileExpiration = new TimeSpan(0, 0, 30, 0)
        }

That's what I do next:
1. Click "Select" button.
2. When open file dialog opens, there's no file mask on it.
3. I select any file and upload it.

4. Click "Remove" link
5. Open file dialog again and see the file mask is set correctly.
What should I do to fix that?

Changing forecolor doesnt seem to work in AppointmentDataBound...
The backColor changes just fine..
The ForeColor stays black..

There are, say 2 items in a combobox. How do I set first item (visible for the user with icon and text) and prohibit selecting another item? So combobox should not expand and be "Read-only".

Hi Guys!

I'm beginner in .NET development. But I've learned how to save time with this technology. I'm very impressed with the power of Telerik too.
Well, here is my trouble for now:

I've a grid that show many columns. I need show all the content columns without wrap lines with horizontal scrool activated, like this.
But when I'll configure a grouped column, the horizontal scrool bar disappears and the column content are cropped, like can see here.

Here the grouping code:
         

<GroupByExpressions>

  <telerik:GridGroupByExpression>

    <SelectFields>

      <telerik:GridGroupByField FieldAlias="Evento" FieldName="Evento" FormatString="{0:D}" HeaderValueSeparator=": ">
        </telerik:GridGroupByField>

    </SelectFields>

     <GroupByFields>

      <telerik:GridGroupByField FieldName="EVENTO" SortOrder="Ascending"></telerik:GridGroupByField>

     </GroupByFields>

   </telerik:GridGroupByExpression>
</GroupByExpressions>

Can anybody help me?

Hi,

I am trying to add checkboxcolumn to support selection of rows in the RadGrid Control

I have tried both client and server side approaches but have issues with both the approaches. I have ran throught the samples provided
 the server side approach seems to work fine.

My Requirement is to be able to  capture the selected rows on the server side apart from selecting and deselecting the rows
on the grid. let me know the suggested apprach.

I have tried the Server side approach but the Toggle events are getting fired in wrong order.
For example if I select the Checkbox in the HeaderRow the ToggleSelectedState gets fired on first check but on unchecking the
same CheckBox ToggleRowSelection gets fired henceforth whihc is not what the expected behaviour should be. Please see attached file for the radgrid aspx code.

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn">
<HeaderTemplate>
<asp:CheckBox ID="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True" runat="server"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" OnCheckedChanged="ToggleRowSelection" AutoPostBack="True"
runat="server">


If I had to use the Client side approach how will I be able to capture the selected rows on the server side. If you can provide us some sample as attahced project It would be of great help!

<telerik:GridClientSelectColumn UniqueName="grdClinetSelectCol"></telerik:GridClientSelectColumn>

</asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>

Thanks
Kumar
