Hi,
I am using two Rad grids on one of my page. There are some DateTimeColumns created for each of them for DateTime fields. Dates are displayed correctly in DateTime column. 
When I apply filter on DateTime column, it works in one grid but throws exception in another grid, although code is same for both. There is no custom filtering.

For both grids, DateTimeColumn is added programmatically as below:
-------------------------------------------------------------------------------------------------------------------------
GridDateTimeColumn boundColumn = new GridDateTimeColumn();

ProductsGrid.MasterTableView.Columns.Add(boundColumn);
boundColumn.PickerType = GridDateTimeColumnPickerType.DatePicker;
boundColumn.FilterControlWidth = Unit.Pixel(100);
boundColumn.HeaderStyle.Width = Unit.Pixel(110);
boundColumn.DataField = col.SystemName;
boundColumn.UniqueName = col.SystemName;
boundColumn.EnableTimeIndependentFiltering = true;
boundColumn.HeaderText = col.FriendlyName;
boundColumn.DataFormatString = "{0:dd/MM/yyyy}";
boundColumn.AutoPostBackOnFilter = true;
boundColumn.SortExpression = col.SystemName;

boundColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo;
boundColumn.ShowFilterIcon = true;

boundColumn.Display = col.Visible;
-------------------------------------------------------------------------------------------------------------------------

Exception I am getting while filtering by DateTime Column is :

-------------------------------------------------------------------------------------------------------------------------
Exception Type: Telerik.Web.UI.ParseException

Message: Neither of the types 'String' and 'DateTime' converts to the other

Hi,

I am using telerik version 2013.3.1324.35.  I tried to insert appointment without clicking any button. Please see attached image for example. It worked fine if I use tab key after I fill in data. I would like it to be save and show data in schedule when I click on another timeslot after I fill in data. 




 Thanks in advance.

Best regards,
Ei 

I would like a telerik tool not to place blank lines between sections of an editor when the user clicks the 'save' button.
I am new to working with Telerik tools.
I have an existing VB.net 2010 web application that uses telerik tools. This application has a user interface for the users to edit 'templates'. When you hit the save button on the application, blank lines are automatically inserted between various parts of a 'letter' that is being generated.

When the editor is being used, there are tabs for preview, html, and design.

I have gone into the 'html' editor to remove the extra <br></br> tags. However the same tags keep appearing. Thus I am wondering if you can tell me what I can do to keep the blank lines from appearing?

To help me, I thought I would show you some code that is being used so you can see where the telerik tool is being accessed;

Hello there.

I'm rather new to the telerik world so please bare with me.
C#, Asp.net.

Im currently having a RadGrid load my content from some DObjectDataSource.

Now i want to make my own insert template, with a asp textbox.
I've done this like so:

RadGrid > MasterTableView > Columns > GridTemplateColumn > InsertItemTemplate.

Within the InsertItemTemplate i have created a asp textbox:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

From my codebehind id like to be able to acess this to set it's value and later pull the value and save it to the database.

Is anyone able to make me a working example of getting the contents of a asp textbox from within the InsertItemTemplate? 
It would be much appriciated.

Thanks in advance.

I have a radbutton on the right side of the page. When I click on it a vertical scroll bar briefly pops up and then the clientclicked function is called. The problem is that when I click on the right side of the image button the clientclicked function does not get called. When I click on the left it functions as planned. It seems the vertical scroll is forcing the button to move to the left putting the right side of the button out of range of the click.

here is a piece of code and attached are screenshots.

my page structure looks like this:


When any kind of events in the radgrid (Paging, Filtering) the modal tooltip disappears.  Any ideas?

Hi,

I'm using a Rad Grid Control in which I want to display a Rad Context Menu. The Javascript function supposed displaying the Rad Context Menu in RadGrid throws an error message as soon as "menu.Show(evt)" is executed. The error message is "Microsoft JScript runtime error: Object doesn't support property or method 'Show' ".
It seems that the javascript code does not recognize my RadMenu1 control.
Here is the code for the function I'm using:

<script type="text/javascript">
function RowContextMenu(index, e) {
document.getElementById("radGridClickedRowIndex").value = index;
 
var menu = $find("<%=RadMenu1.ClientID %>");
  var evt = e.get_domEvent();

menu.Show(evt);

e.cancelBubble = true;
e.returnValue = false;

if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
this.SelectRow(this.Rows[index].Control, true);
}
</script>

Please, How do I fix this?
Thanks,

Hello, 

I have this in my aspx page:

<telerik:RadAutoCompleteBox

         ID="MyControl" runat="server" Width="400" DropDownHeight="150"

         DropDownWidth="500"

         SelectMethod="MySelectMethod"

         InputType="Text">

     </telerik:RadAutoCompleteBox>

             

In my code-behind, I have this:

01.Public Function MySelectMethod() As AutoCompleteBoxData

02.    Dim data As DataTable = GetChildNodes("a", "139")

03.    Dim result As New List(Of AutoCompleteBoxItemData)()

04. 

05.    For Each row As DataRow In data.Rows

06.        Dim childNode As New AutoCompleteBoxItemData()

07.        childNode.Text = row("field1").ToString()

08.        childNode.Value = row("field2").ToString()

09.        result.Add(childNode)

10.    Next

11. 

12.    Dim res As New AutoCompleteBoxData

13.    res.Items = result.ToArray()

14. 

15.    Return res

16.End Function

17. 

18.Private Function GetChildNodes(ByVal searchString As String, ByVal countryList As String) As DataTable

19.    ' Some code that works

20.End Function

21. 

22.Private Function GetData(selectCommand As SqlCommand) As DataTable

23.    ' Some code that works

24.End Function

MySelectMethod is returning the records that I am expecting, given that the parameters are hardcoded. However this are the problems that I encounter:

1) The list of records is not appearing. 
2) My text-input goes away after getting the list of records
3) MyControl.Text property is empty

Anyhelp on this one? I badly need specifically #3 since it is a parameter that I need to pass dynamically. 

I have a situation where RadMenu, sometimes, on page load shows completely malformed for a split second, after which it shows and works properly. It does not happen all the times, it is most pronounced on new page load (not from cache), but it may happen even when all resources are pulled from local cache.
The RadMenu item is actually inside a Table element, in an include file, used by multiple pages, yet this problem appears exclusively on one specific page

I have recorded the screen and extracted what the menu looks like at the split second when it is malformed. It is big enough to be annoying even though it does not happen all the times. I have also attached what it looks like when it is properly rendered, for comparison.

How do I go about finding what is causing the problem?
