[Solved] Disabling a command button in a gridview

I have a grid with a column of GridViewCommandColumn and I wish to programmatically disable certain buttons.

I'm after something akin to;

foreach (Telerik.WinControls.UI.GridViewRowInfo gridItem in HeaderGridview.Rows)
{
if (gridItem.Cells["Send"].Value.ToString() == "TO BE SENT")
gridItem.Cells["Resend"].Enabled = false;
}

I've googled it to death and can't find any samples anywhere.

Anyone got an ideas?

How to generate average series of two series?

Let's say I have two series on a RadChart -- values versus time. Is there a built-in function I can use to generate a third series which is the average of the first two series? I want to be able to take N individual series and show the average of all N series as a single series. Can I do this?

Chart (obsolete as of Q1 2013)

[Solved] MDI Form, avoid duplicate opened forms

Hi there,

I am currently developing an MDI application exploiting your Raddock Control.

As I am using forms as tabbed windows, I would like my application not to create a new tab (a second one), if the form is already open.

Currently I am using the following workaround and nonetheless I don’t like very much this way J

private void AddTabbedForm(BaseForm form)

{

    if (this.radDock1.DockWindows.DocumentWindows.Where(w => w.Text == form.Text).Count() > 0)

    {

        this.radDock1.ActivateWindow(this.radDock1.DockWindows.DocumentWindows.Where(w => w.Text == form.Text).First());

        return;

    }

      form.MdiParent = this;

    form.Show();

}

Any hint to have it implemented in a more elegant way?

Thank you very much
Davide

Solution: Natural Sort on column

A few threads have been posted over the years to ask about natural sorting, which is clicking a column header to go Ascending, Descending, then back to the default unsorted mode on the third click. I looked around for a tri-state or three-state toggle and didn't find any info. Very helpful but incomplete info is found here and here, so I thought I'd provide C# code to help anyone else looking to do this. Some threads refer to MasterGridViewTemplate.AllowNaturalSort but that property no longer exists. My code is adapted from the second forum posting referenced. It looks like the library has changed since Sean wrote his code.

Telerik.WinControls.Data.SortDescriptor.Direction is of type System.ComponentModel.ListDirection, and that enum only has two values. So the Boolean _sorted is used - if the grid is sorted in ascending or descending order, then use the sort order, but if we click past descending order, set _sorted to false (natural sort!) and clear the SortDescriptors.

Of course clearing SortDescriptors means this only works with single column sorting. Maybe someone will follow-up here with a solution that works with multiple columns.

HTH

using System.ComponentModel;

bool _sorted = false;

ListSortDirection _previousGridColumnSortDirection;

private void radGridView1_SortChanging(object sender, GridViewCollectionChangingEventArgs e)

{

try

{

Telerik.WinControls.Data.SortDescriptor sortField;

// Only proceed if we are changing an existing sorting (not starting a new one)

// Make sure we have an item

if (e.NewItems != null && e.NewItems.Count > 0)

{

sortField = (Telerik.WinControls.Data.SortDescriptor)e.NewItems[0];

if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.ItemChanging)

{

// If the current SortOrder is Ascending, and the previous SortOrder

// was Descending, then clear the sorting.

if (_sorted)

{

if (sortField.Direction == ListSortDirection.Ascending &&

_previousGridColumnSortDirection == ListSortDirection.Descending)

{

_sorted = false;

radGridView1.MasterGridViewTemplate.SortDescriptors.Clear();

}

//Save the SortOrder for the next iteration

_previousGridColumnSortDirection = sortField.Direction;

}

else

{

_sorted = true;

_previousGridColumnSortDirection = sortField.Direction;

}

if (e.Action == Telerik.WinControls.Data.NotifyCollectionChangedAction.Add)

{

_sorted = true;

_previousGridColumnSortDirection = sortField.Direction;

}

catch

{

}

[Solved] grouped columns with wraped text

Hello,

I have Winform RadGridView with grouped columns header. I will wrap the long text.

radGridView1.AutoSizeRows = true;

radGridView1.Columns["column1"].WrapText = true;

radGridView1.Columns["column1"].Multiline = true;

Error after view definition, See picture in attach.
Without grouped columns header works well.
Any suggestions?

Regards,
Elek

[Solved] Custom GridDataCellElement for RadGridView. Adding logic to CreateChildElements

Hey Guys

I have a problem where i wish to add logic into the CreateChildElements method which, based on the value of a given cell in the row will display different controls.

When CreateChildElements is called, the GridViewColumn and GridRowElement (which have been set in the contructor) are Null, as if they are not in the same context.

This is what i currently have (Please notice the CreateChildElements Method)

#region GridDataCellElement

public class GridDataCustomCellElement : GridDataCellElement

{

#region Locals

private RadImageButtonElement radButtonElementViewOrder;

private RadImageButtonElement radButtonElementNewOrder;

public GridViewColumn thisColumn;

public GridRowElement thisRow;

#endregion

#region Constructors

public GridDataCustomCellElement(GridViewColumn col, GridRowElement row) : base(col, row) { thisColumn = col; thisRow = row;}

#endregion

#region Events

void radButtonElementNewOrder_Click(object sender, EventArgs e)

{

Main newOrder = new Main(GetFolderPath(thisRow.GridControl.CurrentRow.Cells[2].Value.ToString()) + "\\" + thisRow.GridControl.CurrentRow.Cells[0].Value.ToString());

newOrder.MyParentForm = (SalesOrderingClient.Home)thisRow.GridControl.FindForm();

newOrder.IsCopyOrder = true;

newOrder.ShowDialog();

}

void radButtonElementViewOrder_Click(object sender, EventArgs e)

{

// Build order object

SalesOrderingObjects.Order objOrder = SalesOrderingObjects.Order.LoadOrder(GetFolderPath(thisRow.GridControl.CurrentRow.Cells[2].Value.ToString()) +

"\\" + thisRow.GridControl.CurrentRow.Cells[0].Value.ToString());

// Build session object

Session s = new Session(objOrder);

// Display Order

Order o = new Order(s);

o.ShowDialog();

}

#endregion

#region Overrides

/// <summary>

/// Create new controls and add them to cell

/// </summary>

protected override void CreateChildElements()

{

// Set up controls and add them to this cell

Home h = new Home();

radButtonElementViewOrder = new RadImageButtonElement();

radButtonElementViewOrder.ButtonFillElement.BackColor = Color.Transparent;

radButtonElementViewOrder.ButtonFillElement.BackColor2 = Color.Transparent;

radButtonElementViewOrder.ImageAlignment = ContentAlignment.MiddleRight;

radButtonElementViewOrder.BorderElement.Width = 0;

radButtonElementViewOrder.Image = h.IconImageLIst.Images[1];

radButtonElementViewOrder.ToolTipText = "View Order";

this.Children.Add(radButtonElementViewOrder);

radButtonElementNewOrder = new RadImageButtonElement();

radButtonElementNewOrder.ButtonFillElement.BackColor = Color.Transparent;

radButtonElementNewOrder.ButtonFillElement.BackColor2 = Color.Transparent;

radButtonElementNewOrder.ImageAlignment = ContentAlignment.MiddleRight;

radButtonElementNewOrder.BorderElement.Width = 0;

}

/// <summary>

protected override SizeF ArrangeOverride(SizeF finalSize)

{

// If there are more than 1 controls in this cell

// Setup dimensions and position and modifiy controls

RectangleF btn1 = new RectangleF(20, 12, 36, 36);

RectangleF btn2 = new RectangleF(58, 12, 36, 36);

this.Children[0].Arrange(btn1);

this.Children[1].Arrange(btn2);

//}

return finalSize;

}

/// <summary>

/// Set the cells theme, if not done, cell does not inherit theme as it is custom

/// </summary>

protected override Type ThemeEffectiveType

{

get

{

return typeof(GridDataCellElement);

}

public override bool IsCompatible(GridViewColumn data, object context)

{

return data is RadLabelColumn && context is GridDataRowElement;

}

#endregion

#region Private Methods

string GetFolderPath(string status)

switch (status)

{

case "Saved":

folder = Common.SavedOrdersFolder;

break;

case "InProgress":

folder = Common.InProgressOrdersFolder;

break;

case "Sent":

folder = Common.SentOrdersFolder;

break;

case "Requested":

folder = Common.RequestedOrdersFolder;

break;

default:

folder = Common.UserDataBaseFolder;

break;

}

return folder;

}

This is what i would like to do:

protected override void CreateChildElements()

{

// Set up controls and add them to this cell

Home h = new Home();

switch(SOMETHING GOES HERE)

{

case ?:

radButtonElementViewOrder = new RadImageButtonElement();

radButtonElementViewOrder.ButtonFillElement.BackColor = Color.Transparent;

radButtonElementViewOrder.ButtonFillElement.BackColor2 = Color.Transparent;

radButtonElementViewOrder.ImageAlignment = ContentAlignment.MiddleRight;

radButtonElementViewOrder.BorderElement.Width = 0;

radButtonElementViewOrder.Image = h.IconImageLIst.Images[1];

radButtonElementViewOrder.ToolTipText = "View Order";

this.Children.Add(radButtonElementViewOrder);

radButtonElementNewOrder = new RadImageButtonElement();

radButtonElementNewOrder.ButtonFillElement.BackColor = Color.Transparent;

radButtonElementNewOrder.ButtonFillElement.BackColor2 = Color.Transparent;

radButtonElementNewOrder.ImageAlignment = ContentAlignment.MiddleRight;

radButtonElementNewOrder.BorderElement.Width = 0;

radButtonElementNewOrder.Image = h.IconImageLIst.Images[0];

radButtonElementNewOrder.ToolTipText = "Copy Order";

this.Children.Add(radButtonElementNewOrder);

radButtonElementNewOrder.Click += new EventHandler(radButtonElementNewOrder_Click);

radButtonElementViewOrder.Click += new EventHandler(radButtonElementViewOrder_Click);

break;

case ?:

// ADD SOME DIFFERENT CONTROLS

break;

}

Please tell me if this is possible, or if there is an alternative way of doing this?

Many Thanks
Tim
