WpfControls.AutoCompleteTextBox TestTextBox = new WpfControls.AutoCompleteTextBox();

This is about ComboBox used in Winforms. I need to stop the selected item being heighlighted. I know I can get it done if I set the style of the combobox to ComboBoxStyle.DropDownList.
But I'm looking for a solution where I don't have to use that. Instead, at the moment what I have done is using ComboBoxStyle.DropDown.
I don't have any other option, because if I set it to DropDown, I have to deal with some other issue in my code. It's due to something else which I cannot avoid.
Can someone suggest an alternative pls ?
use the following code in your form's Paint event.
private void myForm_Paint(object sender, PaintEventArgs e)
{
comboBox1.SelectionLength = 0;
}
or pass focus to another control in your combo box selected index changed event:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
comboBox2.Focus();
}
I'm trying to drag an item from a listbox to a textbox in WPF.
I can't get any code that will let me do this.
Thanks
Use selection change event of listbox
private void listBox2_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
ListBoxItem i = (ListBoxItem)listBox2.Items[listBox2.SelectedIndex];
s = i.Content.ToString();
DragDrop.DoDragDrop(listBox2, i.Content.ToString(), DragDropEffects.All);
}
I have a hyperlink button colum in silverlight telerik radgridview, as a cell template.
I am using MVVM.
When i click on the hyperlink button, how can i get its row's values(atleast in the code behind)..?
Thanks in advance..
You need to use the ParentOfType extension method to get hold of the row containing the button.
Once you have the row you can cast the item type to your viewmodel and access the properties of it.
Make sure you have a using statement for the extension method:
using Telerik.Windows.Controls;
private void Button_Click(object sender, RoutedEventArgs e)
{
var parent = (sender as Button).ParentOfType<GridViewRow>();
var rowVM = parent.Item as YourVmClass;
}
If you are using MVVM you can also use the EventToCommandBehavior.
This allows you to execute all events as commands. You can then handle the command in your viewmodel.
I am using a checkbox on expander. I want, when I check that checkbox ,it will select all rows of list view those are coming under that expander.
set the listview's selectionmode to Multiple' or 'Extended and
on the CheckBox_Checked event you can write the code to select the rows of listview
private void CheckBox_Checked(object sender, RoutedEventArgs e)
{
listview1.SelectAll();
}
Try this inside your checkbox_click events handler:
listView1.BeginUpdate();
foreach (ListViewItem i in listView1.Items)
{
i.Selected = true;
}
listView1.EndUpdate();
Which gives you a bit more flexibility.
I have a problem using custom made UserControl in Silverlight Page.
The UserControl is generally a rectangle containing a smaller rectangle inside.
I want to use the UControl in a Silverlight MainSite.
i've implemented a method on mouse button down for a smaller rectangle called in here Button1:
public void Button1_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
MessageBox.Show("Hello");
}
How can i use it from a MainSite? From there I can only implement a method like:
private void ImportedControl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
firstLeaf.Button1_MouseLeftButtonDown(sender, e);
}
I can not implement a method for Button1.
How can i mek this Work?
HELP:)
I am still not sure I understand the question, but let me take a swing at an answer. Why don't you use a real Button and just template it with a rectangle? This way you get all the benefits of actually having a button while having it look like a rectangle, including the Click event.
Here is a post Scott Guthrie did on control templating with a button.
