How I can loop through all row of my grid and detect only row with checkbox column checked ?

i use this solution and got error :  

-------------------------------------------------------------------------------------------------------

Error:

"System.NullReferenceException: 'Object reference not set to an instance of an object.'Telerik.WinControls.UI.GridViewCellInfo.Value.get returned null."
-------------------------------------------------------------------------------------------------------

Code:

IList<GridViewRowInfo> gridRows = new List<GridViewRowInfo>();
foreach (GridViewRowInfo rowInfo in radGridView.ChildRows)
{
    bool isChecked = (bool)rowInfo.Cells["CheckboxColumn"].Value;
    if (isChecked == true)
    {
        gridRows.Add(rowInfo);
    }
}

How I can search through all row of my grid and detect only row with checkbox column checked ?  ( Note : user change value and select checkbox at run time ... )

i use this code and got an error : 

------------------------------------------------------------------------------------------------------------------------------------

my expected effect is like the attcached picture.

 How can I collapse the Titlebar ?

    this.FormElement.TitleBar.Visibility = ElementVisibility.Collapsed;

    => Not working

Code

Public Function NuevoExport(ByVal Grilla As RadGridView, ByVal Grilla2 As RadGridView) As Boolean

 For fila = 0 To Grilla.RowCount - 1
                For col As Integer = 0 To Ncol - 1
                    exHoja.Cells.Item(fila + 2, col + 1) = Grilla.Item(col, fila).Value
                Next
            Next

So after i update data, gantt resets the position to the starting position, and i want to remain the same position

how to do that ?

Hi

I want to remove the shadow of the ribbontabs if they are drop-downed. Is there a possibility?

I tried the following:

            this.radRibbonBar1.RootElement.EnableBorderHighlight = false;
            this.radRibbonBar1.RootElement.EnableElementShadow = false;
            this.radRibbonBar1.RootElement.EnableFocusBorder = false;
            this.radRibbonBar1.RootElement.EnableFocusBorderAnimation = false;
            this.radRibbonBar1.RootElement.EnableHighlight = false;
            this.radRibbonBar1.RootElement.EnableRippleAnimation = false;

Thank you in Advance

Kind Regards,

Hi

I adapted the height of a radRibbonBar with (radRibbonBarExpand):

            this.radRibbonBar1.RootElement.MaxSize = new System.Drawing.Size(0, 120);
            this.radRibbonBar1.RootElement.MinSize = new System.Drawing.Size(0, 120);

And wanted to change the height of the drop-downed tab the same size and tried (radRibbonBarDropDown):

            this.ribbonTab1.MinSize = new System.Drawing.Size(0, 20);
            this.ribbonTab2.MaxSize = new System.Drawing.Size(0, 50);

but the height stays the same. How is it possible to change this height?

Thank you in Advance

Kind Regards,

Dominik

Hello, 

actually I am testing the RadGridView.

I made a Grid with three columns. One of them as multiline textbox.

So, my problem is to set the row height dynamically with the number of the lines of the multiline cell.

The user should see all the lines of the multiline cell if the cell will be in edit mode.

I have read all the threads about that, but I don‘t find a solution.

Any help from you.

thank you and best regards
