Is Windows Forms really the right forum for this question?

I have been trying to change color of tab control. But all i could do is change the color of tab - pages present on the tab control. It looks very awkward that tab pages of different color and the panel on which these pages are present is default color. Please if any one knows how to change the color of the tab control...

VB.NET doesn't support that but C#. You can change the color of a tab and its page color but you can't change the color of tab control in vb.net. I assumed you are not going to use API to do that.
I wish there were such feature in VB.NET.
What a curious mind needs to discover knowledge is noting else than a pin-hole.

I have a main form where the user selects a customer from a drop down box. On this form is also a button that opens another form as a dialog that allows the user to enter a new customer. The user clicks "Save" on the new customer dialog and the customer is saved to the database and the main form becomes active again. I can't figure out how to update the combobox so that it displays this new customer in the list.
The combobox is bound to a datasource. I know the code to create and save a new customer is working since the change is reflected in the database. The new customer also appears in the combobox BUT only after I close and run the application again.
<br />
if (result == DialogResult.OK)<br />
{<br />
<br />
}<br />

Figured it out. The quick answer is to simply fill the dataset again. However, if you have any filters elsewhere on the form that use the same dataset, be prepared to deal with exceptions. You must put some data back into the dataset before any calls to the filter are made. This was a big issue for me and took me about 8-10 total hours of debugging to figure out. Then again, I am a complete noobie.

Glad you figured it out. But you may want to take a look at Update Controls .NET. These controls update themselves from your own data objects, not from datasets. So when you add your customer object to your list, it would automatically refresh the drop down.

Thanks for the link. I have checked it out and I will at least experiment with some of those controls.

Hi --
I'm building a GUI application in Visual C++ 2003 using the drag-and-drop Windows Forms toolbox. Does anyone know a way to build docked windows/forms (tabbed windows) into an application? I'm aiming for a look similar to the docked windows in, for example, visual studio.
Thanks in advance!

These are great controls. I have used them in the past and they are very easy to work with.

How do they work with Visual c++.net (2003 or later).
Thanks,

I have only used them from C#, but if you are doing managed C++ development they should work the same way. I have used them in VS2003 and VS2005 and both have worked great.

As Richard pointed out, the controls from Divelements are great. They have a very simple programming model and a polished look to them.

You could also take a look at DotNetBar[^]. They are very good, plus they support a wide variety of styles.

Hi,
I am developing a software for winforms in VS 2005, but the GUI design is done by someone else. I can't let the designer to enter my source code for many reasons. Is there any tool that I can use to design my GUI without accessing the code ?
Thank you,
Yuval

You can use visual inheritance.
The designer change the base forms that your code inherit.
Any changes to base forms (that contain no code) will reflect to your child forms.

This is exactly what WPF was designed to solve. Have a look at WPF and XAML.

i want to bind datagried with an array list full by objects ?
|
|
|
|

The easiest way to bind a data grid with an array list (or any object container, for that matter) is to use Update Controls .NET. You can drop an UpdateGrid on your form and implement the GetItems event. This event just returns the array. Then implement GetCellValue to get the values to display. When the user changes a value, the control fires SetCellValue.
Here's an example:
private System.Collections.IEnumerable itemsGrid_GetItems()
{
return _order.Items;
}
private object itemsGrid_RowAdded()
{
return _order.NewItem();
}
private void itemsGrid_RowDeleted(object tag)
{
_order.DeleteItem((Item)tag);
}
private UpdateControls.Forms.ColumnDefinitions itemsGrid_GetColumns()
{
return new UpdateControls.Forms.ColumnDefinitions().
Add("Name", typeof(string)).
Add("Price", typeof(decimal)).
Add("Quantity", typeof(int)).
AddReadOnly("Total", typeof(decimal));
}
private object itemsGrid_GetCellValue(object tag, int column)
{
Item item = (Item)tag;
if (column == 0)
return item.Name;
else if (column == 1)
return item.Price;
else if (column == 2)
return item.Quantity;
else
return item.Total;
}
private void itemsGrid_SetCellValue(object tag, int column, object value)
{
Item item = (Item)tag;
if (column == 0)
item.Name = (string)value;
else if (column == 1)
item.Price = (decimal)value;
else if (column == 2)
item.Quantity = (int)value;
}

Moved to the C# forum:
http://www.codeproject.com/script/comments/forums.asp?forumid=1649&select=1912526#xx1912526xx[^]
[/modification]
I am implementing a custom IExtenderProvider derived class so I can dynamically set the following properties on a control:
Required (using an ErrorProvider)
Description (ToolTip)
Errors (using an ErrorProvider)
Caption
I have everything working except for the caption. Ideally, I would like to add a Label control to the form for the given UI element. I know how to draw the label text myself, but that doesn't give me any of the accessability features that I gain when using a label.
The problem I'm running in to is that I can get the label to appear at design time but not at run time. Essentially, when I detect that a new control has been added I try to add a new label control (positioned appropriately) to the parent's Controls array. This works fine at design time but at run time the Parent property of the control I'm extending is null.
I'm trying to do this using an IExtenderProvider so I don't have to create subclassed versions of the UI controls to add a caption. In case you want the background, the project I'm working on needs to allow a dynamically rendered UI based on various pieces of meta data contained in the business object. The business object can be customized by the end-user through an admin interface, so I will never know what fields will be present and what their captions should be until it is time to actually render the screen.
Has anybody done anything similar to this? I've pretty much exhausted the information available on Google, which isn't much beyond creating a simple provider.

Sorry that it has taken so long to get back to you, but the way to do this is fairly straight forward. In your Set... method, add a handler for the ParentChanged event like this:
txtItem.ParentChanged += new EventHandler(txtItem_ParentChanged); Then, your method will look like this:
void txtItem_ParentChanged(object sender, EventArgs e)
{
TextBox control = sender as TextBox;
string labelText = Get...(control);
LabelExtender(labelText, control);
}Finally, create a method for the label extender:
private void LabelExtender(string labelText, TextBox txtBox)
{
Point loc = txtBox.Location;
Label label = new Label();
label.Name = string.Format("label{0}", Guid.NewGuid().ToString());
label.Location = loc;
label.Text = labelText;
label.AutoSize = true;
label.TabIndex = 0;
label.Size = new System.Drawing.Size(35, 13);
label.Visible = true;
if (txtBox.Parent != null)
{
txtBox.Parent.Controls.Add(label);
}
txtBox.Left += label.Width;
if (txtBox.Parent != null)
txtBox.Parent.Invalidate();
}
