How do I increase space between Checkbox's text and the checkbox?

I'm working with a .NET WinForms form. I'm adding a new Checkbox control to the layout, but I need its text and checkbox elements to align with existing controls. Is it possible to bump out my Checkbox's checkbox element from its text element? Or am I better off creating a separate Label control?
thanks

Try using the following settings for your CheckBox controls:
checkBox1.AutoSize = false;
checkBox1.CheckAlign = System.Drawing.ContentAlignment.MiddleRight;
checkBox1.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
You will have to set the location and the size of the control yourself now.

Just create a custom (composite) control by adding a checkbox and a label. set the spacing as per need.

changing the DisplayMember of Syncfusion ComboBoxAutoComplete

I am working with Syncfusion tools, and am trying to add a ComboBoxAutoComplete control to a Windows form. I have a DataTable that I'm using as my DataSource with two columns: ID and Name. I set the DataSource, DisplayMember, and ValueMember properties like so:
ComboBox1.AutoCompleteControl.DataSource = table
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"
The control loads correctly, but it appears that the DisplayMember does not get applied. The control will display only the ID of the selected item. When I expand the drop-down, it displays the entire table (both columns). I tried setting the DisplayMember and ValueMember directly on the AutoCompleteControl, but those properties do not exist. Is there a different property that is used to control what text is displayed in the ComboBoxAutoComplete control?

We have prepared the simple sample in which we have assigned data table to "DataSource" property of AutoCompleteControl inside the ComboBoxAutoComplete to enable the AutoComplete features.
To display the value based on DisplayMember assigned the Data table columns to “Columns” (collection property) of AutoCompleteControl and set “MatchingColumn” value as True for which column has been set in DisplayMember.
Please check with the sample from below location.

Silverlight - Get Telerik RadGridView column and Set content for toggle button

I have a Telerik RadGridView and wish I could set some column's IsVisible property to false or true when I click a toggle button.
I can only get the column by grid.Columns[1].IsVisible = False.
I wanted to set it like this grid.Columns["ColumnName"].IsVisible, but failed. Is that possible?
I use x:Name = "ColumnName"
How can I set content property for this toggle button, for example as "Display" at first and when click it, content change to "Hide"?

You should use UniqueName instead of x:Name

Check ColumnBase.ColumnFilterMode Property, you can customize your filter mode for specific column.
This is WPF grid Reference, but silverlight grid also have such properties. check Filter Modes and Custom Filtering..
Code snippet for reference:
foreach (GridColumn column in grvAvailableCompnents.Columns)
{
column.OptionsFilter.FilterPopupMode = FilterPopupMode.CheckedList;
column.OptionsFilter.AutoFilterCondition = AutoFilterCondition.Contains;
}
Reference:
GridControl.CustomRowFilter Event

ComboBox Input ,wpf

I have a ComboBox and its items source is an SQL table.
I would like that the user will choose the value he likes and if the value is not in the list, he would be able to type the value into the ComboBox. Is it possible?
Thanks.

You need to set the IsEditable property of the ComboBox to True. This will allow you to edit the contents as well as select any of the populated items in the combo box.
