Hi,

I think I will get points on this also !

The default behavior of System.Windows.Forms.Button control is when it is visible true then only it will fire an event of Escape or Enter/Return key (When Form object's AcceptButton or CancelButton property is set to particular button). And if it is visible false, it will not fire any event.

Now in RADButton, it always fires event even if control is visible false !

Hi,
   i'm using Visual Studio 2008 with SP1 and Telerik Controls fro WinForms Q3 2008 SP2 and i have problems with the Element Hierarchy editor on a form: on every RADControl i chose to 'Edit UI elements' the Editor window appears, but when i move from root node to another node the window disappear and Visual Studio starts to show the message in object (RootRadElement cannot be converted to type 'System.Windows.Forms.Control') and i must restart the IDE. Any suggestion to resolve this problem? i cannot work in this manner....

This is the .Designer.cs files generated from VS



Thanks for any suggestions

hello experts,

When using a sizable RadForm, the Mouse pointer does not change to the double arrow pointer when over the size grip, only when over the border, which is rather inconvenient given that the Office 2007 blue style draws only a very narrow border (1 pixel or so). IMHO the mouse pointer should change when over the Size Grip (and allow re-sizing of the form).

I have created a number of usercontrols that I want to dynamically add to
dockpanels based on user input -

It's all straightforward enough but the users have varying screen sizes
and some of the controls have a fair amount of height.
My problem is I cannot get auto scroll bars when the contents of the docking
panel exceed the boundaries. In your demo apps I see some of the windows
do gain scroll bars when the contents exceed although not all do.

Is there a property / method for the dockpanel that automatically creates scrollbars
based on the contents in the dockpanel ? Or do we have to implement this
ourselves manually ?

I'm trying to figure out a way to have a ContentPanel size itself automatically based on the amount of text in a Label control.  I've tried various ways of automatically sizing the Label in hopes that the ContentPanel would enlarge to accommodate the content, and when that failed I tried programmatically changing the size of the GroupElement to match the size of the label.  None of my attempts has been successful.

Can anyone give me some tips on whether this is possible and if so how to accomplish it?

Thanks,
Josh

Hi is there a way to stop the beeps when tabbing around a gridview?

Hi,
I am using check box column to select row.
In fact when the check box is selected, I am storing the DataBondItem of checked row in an Arraylist.

The constraint here is, at a time only one check box has to be checked.
When the next row is checked. The privious check box should be unchecked.

The above is the total functionality.

I am using, BeginEdit and ActiveEditorValuechanged event to perform the above functionality.

The problem here is I am getting 'Object Reference Error' once in a while.

Can anybody suggest better way to obtain the above functionality ?

Current Code for reference :

 void radGrid_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
        {
            currentRowIndex = e.RowIndex;
            CurrentRowDataItem = this.radGrid.Rows[e.RowIndex].DataBoundItem;

            try
            {
                CurrentRowDataItem = this.radGrid.Rows[e.RowIndex].DataBoundItem;
                if (radGrid.Columns[e.ColumnIndex] is GridViewCheckBoxColumn)
                {
                    //When the editor is clicked properly
                    if (radGrid.ActiveEditor != null && radGrid.ActiveEditor.Value != null)
                    {
                        //create handler for active Editor
                        radGrid.ActiveEditor.ValueChanged += new EventHandler(ActiveEditor_ValueChanged);
                    }
                }
            }
            catch { }
        }

        void ActiveEditor_ValueChanged(object sender, EventArgs e)
        {
            //Only when the value is not null
            if (radGrid.ActiveEditor != null && radGrid.ActiveEditor.Value != null)
            {
                //remove the handler, because next time when the editor is clicked new handler wil be created
                radGrid.ActiveEditor.ValueChanged -= new EventHandler(ActiveEditor_ValueChanged);
                try
                {
                    //Here check the any row's check box selected in the Grid or not.
                    if (this.selectedRows != null && radGrid.ActiveEditor != null)
                    {
                        //current data item
                        object item = radGrid.CurrentRow.DataBoundItem;

                        if (radGrid.ActiveEditor.Value.ToString().ToLower() == "true")
                        {
                            this.selectedRows.Clear();
                            this.selectedRows.Add(item);

                            if (PreviousRowDataItem == null || previousCheck == -1)
                            {
                                //previousCheck = currentRowIndex;
                                PreviousRowDataItem = this.radGrid.CurrentRow.DataBoundItem;
                            }
                            
                            //set current index of previously selected row. It has to be checked and set because while sorting index may change
                            previousCheck = GetActualCheck(PreviousRowDataItem);

                            //Uncheck the previously selected
                            if (previousCheck != -1)
                            {
                                //set false if its true
                                if (radGrid.Rows[previousCheck].Cells[0].Value.ToString().ToLower() == "true")
                                {
                                    radGrid.Rows[previousCheck].Cells[0].Value = Boolean.FalseString;
                                }
                            }
                            //change the previous rowdata to current dataitem
                            if (currentRowIndex != -1)
                            {
                                PreviousRowDataItem = this.radGrid.CurrentRow.DataBoundItem;
                            }

                            if (OnSelectionChange != null)
                            {
                                OnSelectionChange();
                            }
                        }
                        //if uncheck clear the selected rows
                        else
                        {
                            this.selectedRows.Clear();
                        }

                        //if the Edit is finished, have to call this Default function otherwise the edit should not be commited
                        bool b = radGrid.EndEdit();
                    }
                }
                catch (Exception ex)
                {
                    Nexus.UI.BaseMdiParent.RaiseException(this, ex);
                }
            }
        }

I am using checkbox column in my grid.
At a time only one checkbox can be in selected state.
how can i do that?

I need to have a windows program display a crawl across the bottom of the window. Would RadRotator do this? I need to have the crawl just run without any human intervention.

TIA - Jeff.
