Hi there.

Hi:

I'm totally new to Rad WinForm controls. 2 hours into it, I have a question:

I have a GridView on an RadMDI parent form.  There's also a button. Clicking the button calss a child form:

 

Dim child1 As New Form()

 

child1 = FrmStdEdit    'where FrmStdEdit is the child form I designed.

 

Dim ChildSize As New System.Drawing.Size(580, 200)

 

child1.Size = ChildSize

child1.Text =

"JTK Form"

 

child1.MdiParent =

Me

 

child1.TopMost =

True

 

child1.Show()

When the child form opens, however, it does so underneath the gridview - even though TopMost is set to true.  Is there a way to change that?

Justin

I get the following error when I am closing the form.  The only operation I have done is to assign a datatable to the grid's datasource.

Hi,
How to disable the right menu in RadSchedule?

Hello

How can I set WPF Look of GridView while runtime ?

I have set DataSource like:

this

.radGridView1.DataSource = local_DataSet.Tables[0];

I like to have the same look like the Grouping sample.

Thanks and best regards
Frank Uray

 

Hi all,

I'm in need of localization for the radgridview contextmenus and the version of telerik used on the project is Q3 2007 SP1. I found how I could change the filteroptions and the filteroperations but I can't seem to get a hold of the sorting ones. I guess you all know what menu I mean if I say it contains the following items: Sort Ascending, Sort Descending, Conditional formatting, etc...

Is it possible to alter the strings for these somewhere or somehow?

Thank you in advance,
Ivan

Hi,
        I am working on rad gridview for winforms. I have a grid with four columns. The first columns is an id field, second column a display field. The third column is a hidden field that has two possible values(lookup, user entry). Based on this the fourth column should show a drop down list or a text box. If the value of the third column is "lookup", we have to get the id value from the id column, query a table with the id and fill the drop down with the resultant values. If the value of the third column is "user entry", we have to show a text box there where user can enter values. Upto this i have done but the problem is, the text box seems to be in locked mode initially when tried to enter data in it. If we try to enter the data after clicking some other columns , then it works fine. I am listing the code below.

public

partial class Test : Form

 

 

{

 

DataTable dtMain;

I am new to RadGrid for WinForm, and have some basic questions:

1.    Upon adding a new row to the grid, I want to write the value in code in one of the 10 cells. I tried by writing this code in the RowChanged event but did not work:  radGridView1.CurrentRow.Cells["WeekNumber"].Value = radSpin1.Value;
How I can achieve this.

2.    I don't want to use spinbutton Editor with a Decimal type column. Please let me know how to change the default Column Editor of a Decimal Type column?

Hello Everyone,

I am using Visual Studio 2008 and telerik rad controls Q3 2008. Inspite of all successful installations when i open my VS 2008 IDE I do not see toolbar with Telerik Controls. I see general microsoft .net toolbars/controls.

Can anyone tell me what I need to do so that I can see all telerik rad controls in a toolbar. I would appreciate any help.

Thank you,

Regards,

I have a RadForm Dialog that sometimes does some lengthy operations.
In this case, the Form does not always repaint, is that the expected behaviour?
Do I always have to implement some Worker Thread pattern when working with RadForm?
