Hi,

I have a hierarchical gridview with checkbox column. I have a checkbox in header as well.
When the header checkbox is checked/unchecked all other rows gets checked/unchecked accordingly.
But when i do the same in Child it is not working properly.
When i check/uncheck header of Child then the child rows of only expanded row should get checked/unchecked but not all the child rows.
Right now its applying changes for all child rows but i want it only for expanded row.

Below is my code:
<
private void AddCheckColumn(fc_rad_dataGridView dataGridView)
        {
            CustomCheckBoxColumn checkColumn = new CustomCheckBoxColumn();
            checkColumn.Name = "IsActive";
            checkColumn.FieldName = "Active";
            if (!dataGridView.Columns.Contains("IsActive"))
                dataGridView.Columns.Insert(dataGridView.Columns.Count - 1, checkColumn);
        }

public class CustomCheckBoxColumn : GridViewCheckBoxColumn
    {
        public override Type GetCellType(GridViewRowInfo row)
        {
            if (row is GridViewTableHeaderRowInfo)
            {
                return typeof(CheckBoxHeaderCell);
            }
            return base.GetCellType(row);
        }
    }

    public class CheckBoxHeaderCell : GridHeaderCellElement
    {
        RadCheckBoxElement checkbox;

        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(GridHeaderCellElement);
            }
        }

        public CheckBoxHeaderCell(GridViewColumn column, GridRowElement row)
            : base(column, row)
        {

        }

        public override void Initialize(GridViewColumn column, GridRowElement row)
        {
            base.Initialize(column, row);
            column.AllowSort = false;
            column.TextAlignment = ContentAlignment.MiddleRight;
        }

        public override void SetContent()
        {
        }

        protected override void DisposeManagedResources()
        {
            checkbox.ToggleStateChanged -= new StateChangedEventHandler(checkbox_ToggleStateChanged);
            base.DisposeManagedResources();
        }

        protected override void CreateChildElements()
        {
            base.CreateChildElements();
            checkbox = new RadCheckBoxElement();
            checkbox.ToggleStateChanged += new StateChangedEventHandler(checkbox_ToggleStateChanged);
            this.Children.Add(checkbox);
        }

        protected override SizeF ArrangeOverride(SizeF finalSize)
        {
            SizeF size = base.ArrangeOverride(finalSize);

            RectangleF rect = GetClientRectangle(finalSize);
            this.checkbox.Arrange(new RectangleF((finalSize.Width - this.checkbox.DesiredSize.Width) / 2, (rect.Height - 20) / 2, 20, 20));

            return size;
        }

        public override bool IsCompatible(GridViewColumn data, object context)
        {
            return data.Name == "IsActive" && context is GridTableHeaderRowElement
                && base.IsCompatible(data, context);
        }

        private void checkbox_ToggleStateChanged(object sender, StateChangedEventArgs args)
        {  
            if (this.ColumnInfo is GridViewCheckBoxColumn)
            {
                bool valueState = false;

                if (args.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On)
                {
                    valueState = true;
                }
                for (int i = 0; i < this.ViewTemplate.Rows.Count; i++)
                {
                    this.ViewTemplate.Rows[i].Cells[this.ColumnIndex].Value = valueState;
                }
            }
        }
    }

Hi,

I have a query on the DataBinding of DataGridView to BindingList object.

I have a Class called Customer having a structure decribed as Below.

 

public class Customer

 

{

 

public int CutomerType { get; set; }

 

 

public string CustomerName { get; set; }

 

}

 

public class LookupData

 

{

 

public int Key

 

{

 

get;

 

 

set;

 

}

 

public string Value

 

{

 

get;

 

 

set;

 

}

 

public override string ToString()

 

{

 

return this.Value;

 

}

}

I have created a BindingList<Customer> and binded with the DataGrid. The Grid has 2 columns

1) GridViewComboBoxColumn - with Data source as List of Lookup data and the FieldName as CustomerType
2) GridViewTextBoxColumn - for CustomerName

Everything works fine , I am able to Add, Update and Delete entries.

But my problem is When I add a new row the , the new customer object is added to the BindingList only after I come out of the Grid row.
 
I want to add a new Customer Item to my BindingList when the user adds a new row and selects a CustomerType.

Note : I checked with Normal Winform Grid and It adds an entry if I select Customer Type alone.

Can you please let me know if there is any option available for this..

Thanks

Hi mates,
We are at the end of developing a client application in winforms (of course using Telerik Winforms controls). But application is going to be large and I want to see opportunities to separate in "modules". 

Dear Admin,

I need to change the height of navigation bar property of the calendar. Also, I need to change the navigation bar images.
I program an application that will be used in a touch screen computer. So, I have to change the size of navigation bar and its images.

Could you please help me?

Thank you in advanced.

Best regards.
