RadGridView中按下Enter键无法退出单元格的问题求助

I’ve run into this exact issue before with older Telerik versions—when you hit Enter in a cell, it creates a new line instead of moving to the next row. Let’s walk through the most common fixes that should get you back to the default expected behavior:

1. Verify the EnterKeyMode Property #

First, double-check your RadGridView’s EnterKeyMode setting. This controls exactly what happens when you press Enter, and it’s easy to accidentally set it to the wrong value.

• In the Visual Studio Designer: Select your RadGridView, go to the Properties window, find EnterKeyMode, and set it to MoveNext or EditNextCell (depending on whether you want the next cell to immediately enter edit mode).
• In code:

  radGridView1.EnterKeyMode = Telerik.WinControls.UI.EnterKeyMode.MoveNext;
  

2. Disable AcceptsReturn on the Cell Editor #

If the EnterKeyMode is already correct, the problem is likely with the default text editor allowing line breaks. You’ll need to override the editor’s AcceptsReturn property when it initializes:

Add this event handler to your RadGridView’s CellEditorInitialized event:

private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    // Target the default text box editor
    var textBoxEditor = e.ActiveEditor as RadTextBoxEditor;
    if (textBoxEditor != null)
    {
        var textBoxElement = textBoxEditor.EditorElement as RadTextBoxItem;
        // Disable line breaks in the editor
        textBoxElement.AcceptsReturn = false;
    }
}

3. Rule Out Theme Interference #

Since you’re using the Visual Studio 2013 theme, it’s possible the theme is overriding the editor’s settings. Test this temporarily by switching to a different built-in theme (like Office2016):

radGridView1.ThemeName = "Office2016";

If the Enter key starts working as expected, you’ll need to either:

• Customize the VS2013 theme to set AcceptsReturn=false for text editors, or
• Keep the CellEditorInitialized handler from step 2 to override the theme’s setting.

4. Check for Custom Keyboard Logic #

Finally, make sure you don’t have any custom KeyDown, KeyPress, or ProcessCmdKey logic in your form or GridView that’s intercepting the Enter key and changing its behavior. Look for code that checks for Keys.Enter and might be handling it manually instead of letting the GridView’s default logic run.
