C#: How to make pressing enter in a text box trigger a button, yet still allow shortcuts such as “Ctrl+A” to get through?

由 半腔热情 提交于 2019-12-03 06:40:16
问题 Sorry for the long title, but I couldn't think of another way to put it. I have this: private void textBoxToSubmit_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { buttonSubmit_Click((object)sender, (EventArgs)e); } } ... in order to make pressing enter in the text box trigger the "submit" button. However, this also prevents shortcuts from going through. (not quite sure what it has to do with that, maybe only multi-key combos?) ShortcutsEnabled is set to true. Thanks in

Use EventTrigger on a specific key

由 给你一囗甜甜゛ 提交于 2019-12-03 05:46:37
I would like to invoke a command using EventTrigger when a particular key is touched (for example, the spacebar key) Currently I have: <i:Interaction.Triggers> <i:EventTrigger EventName="KeyDown"> <i:InvokeCommandAction Command="{Binding DoCommand}" CommandParameter="{BindingText}"/> </i:EventTrigger> </i:Interaction.Triggers> Now how can I specify that this should occur only when the KeyDown occurs with the spacebar? You would have to build a custom Trigger to handle that: public class SpaceKeyDownEventTrigger : EventTrigger { public SpaceKeyDownEventTrigger() : base("KeyDown") { } protected

Click and keydown at same time for draggable jQuery event?

问题 I'm trying to have a jQuery UI event fire only if it meets the criteria of being clicked while the shift key is in the keydown state ( to mimic being held), and if not disable the event. This example uses jQuery UI's .draggable to drag a container div only if the user clicks and holds shift. http://jsfiddle.net/zEfyC/ Non working code, not sure if this is the best way to do this or what's wrong. $(document).click(function(e) { $('.container').keydown(function() { if (e.shiftKey) { $('

问题 In winfrom applications i can have textbox1.keydown event, but i want to achieve same thing in webform (asp.net), so how can i do that? I need to retrieve data from database on this event... 回答1: You can use onkeydown event, which will then call your client side function. Inside the client side function, you can make an ajax call to populate data from database. <asp:TextBox ID="txtName" runat="server" onkeydown="javascript: callMe();" /> function callMe() { $.ajax({ url: 'URLOFTHEFUNCTION',

问题 Regarding the .trigger() method, the Event object, the which property, the JS char codes and the code below, why does the #example input don't get the char a as auto-written value? Did I misunderstand the .trigger() method? <input type="text" name="example" id="example" value="" /> <script> $(function() { var e = jQuery.Event("keydown", { which: 65 }); $("#example").focus().trigger(e); }); </script> 回答1: The mistake you're making is what you're expecting the jQuery's trigger method to do.

Handling arrow keys in a Form

问题 I have just found out that we can't use the KeyDown event directly with a PictureBox . So I have to change my strategy. I decided to add the Keydown event to the actual form: private void FullColourPaletteForm_KeyDown(object sender, KeyEventArgs e) { switch (e.KeyCode) { case Keys.Left: { MessageBox.Show("Left"); e.Handled = true; return; } } } Doesn't get executed. I see no message box when I press the left allow. Instead (and rightly so) it just moves the cusor from control to control. I

How to make individual items in a table selectable in angularjs

由 为君一笑 提交于 2019-12-02 06:51:23
I have a table using ng-repeat... I want to be able to allow the users to select an item in the table using the key 'enter' which is equal to the keydown event 13. When a user clicks enter, I want to be able to focus in on the specific table row and make the variable 'selected' to true. When the user clicks on enter the second time, I want the 'selected' field to be set to false.
