[Solved] Inputbox

Hi,

I would like to suggest an Inputbox for the Winforms control set. I think if you offer a radmessagebox it would only be normal to include an Inputbox.

Thanks

Bottom border missing in selection

Hi,

Sometimes I'm pedantic when it comes to the appearance of the application.
I have a RadGridView called cGrid with events:

private void cGrid_CellFormatting(object sender, CellFormattingEventArgs e)

{

// simple background

e.CellElement.BackColor = Color.FromArgb(186, 220, 230);

e.CellElement.BackColor2 = e.CellElement.BackColor;

e.CellElement.BackColor3 = e.CellElement.BackColor;

e.CellElement.BackColor4 = e.CellElement.BackColor;

e.CellElement.DrawFill = true;

}

private void cGrid_ViewCellFormatting(object sender, CellFormattingEventArgs e)

{

// border color from background

Color color = e.CellElement.BackColor;

// but if IsCurrent or IsSelected the border color should be red

if (e.CellElement.IsCurrent || e.CellElement.IsSelected)

{

color = Color.Red;

}

// single border for nice looking

e.CellElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;

// solid for using only one color

e.CellElement.BorderGradientStyle = GradientStyles.Solid;

e.CellElement.BorderColor = color;

e.CellElement.DrawBorder = true;

}

And set:

this.cGrid.EnableHotTracking = false;

this.cGrid.HideSelection = true;

this.cGrid.MultiSelect = true;

this.cGrid.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect;

And now I see by selecting multiple cells (check attachment).
For cells ch last selected row can not see the bottom border.
Do you know a trick to solve this "problem"?

Image Combobox in radgridview. 2 problems

Hi, my name is Hajun Song from south korea.

I have a radgridview and it has 5 columns and 36 rows
(1 and 2 columns are GridViewTextBoxColumn and
4 and 5 columns are GridViewComboBoxColumn).

I wanna add the images as the combobox's items, so I search and
apply the source base on this example.
http://www.telerik.com/forums/gridviewcomboboxcolumn-that-displays-only-icons-images

When I finished the code and run it, some problems happened.

First, in the first picture,
When the scroll of the table is moved down, some cells not conserned with
image combobox display the images(solid dash line image).
I wanna know how to fix that.

Second, in the second picture, when I open and select the
image of comboBox, some texts are shown as figure.
Although these texts are disappeared if I clicked other place,
but I don't want skip that step. (In upper example source, that has same reaction.)
Can't I fit that? If not, I wanna know how to remove that step.

Third picture is about my source.

Please point out my problem.
And if it is possible, I wanna example source about
successful case of my problems.
Thank you.

WordsProcessing - Value cannot be null.\r\nParameter name: data

Hello, I'm using UI for Winforms on a VSTO outlook plug-ins project. Some Email save to word doc without a problem but some get this error - "Value cannot be null.\r\nParameter name: data".

Here is my code.

var saveAsWord = new SaveAsWord(filePath, _Mail.HTMLBody, _Mail.Subject);
saveAsWord.SaveToWord();

public void SaveToWord()
{
try
{
var provider = new HtmlFormatProvider();
RadFlowDocument document = provider.Import(TextBody);
var providerDocx = new DocxFormatProvider();
using (Stream output = new FileStream(SaveFileTo, FileMode.OpenOrCreate))
{
providerDocx.Export(document, output);
}
}
catch (Exception ex)
{
LogError.LogErrorMessage(ex);
}
}

List View Item to Document window.

I have dragdrop enable on both controls. But i whenever i try to drag an item from the list view over to the document window, it shows the red circle that tells me it cannot drop the object. So i went down the route of implementing PreviewDragDrop to get it working, but then i have no clue how to get the handle of my document window since preview drag and drop is giving me back an RadPageViewTabStripElement and none of the item in there matches a Document window.

Thanks.

Expose more Filter events

Currently the gridview exposes a few events originating from the filter. But I need more. I need to know when the user clicks the filter "textbox" (enter or beginedit) and when the user closes it (leave or endedit). I'm certain internally these events are available, but is there any way to expose them to my code?

Regards,
Martin

How to RadTreeview Text Alignment

Please see my attach screenshot.

As you can see i have 3 nodes and values.
All i want to achieve is to order all 3 values in same position for example:

Destination address: FF:FF:FF:FF:FF:FF
Source address: 00:00:00:00:00:00
Protocol: ARP (0x0806)

My current behavior is:

Destination address: FF:FF:FF:FF:FF:FF
Source address: 00:00:00:00:00:00
Protocol: ARP (0x0806)

How can i do that ?

[Solved] CellFormatting messes RadGridView up when sorting it

Hello

I'm using CellFormatting event to color some cells in my RadGridView. On Form_Load it works fine (see first image). But when I sort the RadGridView it messes the whole thing up (see second image). You can see my code here:

if (e.Column.Name == "va" && e.CellElement.Value != null)
{
if ((e.CellElement.Value.ToString() == "P" && e.Row.Cells["id"].Value.ToString() == "1") ||
(e.CellElement.Value.ToString() == "A" && e.Row.Cells["id"].Value.ToString() == "1") ||
(e.CellElement.Value.ToString() == "E" && e.Row.Cells["id"].Value.ToString() == "1"))
{
e.CellElement.DrawFill = true;
e.CellElement.BackColor = Color.Red;
e.CellElement.NumberOfColors = 1;
}

else if (e.CellElement.Value.ToString() == "P" || e.CellElement.Value.ToString() == "A" || e.CellElement.Value.ToString() == "E")
{
e.CellElement.DrawFill = true;
e.CellElement.BackColor = Color.Orange;
e.CellElement.NumberOfColors = 1;
}
}

Any suggestions how to fix this?

Thanks in advance

[Solved] Context Menu with sub menus via designer

Is it possible to create a right click Rad context menu in the designer with submenu items? Or can it only be done in code.

Is there any suitable rad menu that can be created in the designer with sub menus and be used as a right click menu?

Otherwise I can use the standard .Net menu I guess.

Thanks
