I have a a gridview with a dynamic number of columns and rows. In each of the gridiview cells, a textbox get's added dynamicaly. I need users to be able to tab through these textboxes, but I can't get it to work.
I set the tabindex of the the textbox when it is created in the code behind, however when I try and tab in the page it doesn't work. If I click inside a textbox in the grdiview then pressing tab does nothing at all, If I click outside the gridview I can tab through the other controls on the page, and it will tab into the first cell of the gridiview, and then stop/
Perhaps you can create a javascript method to get a list of all textboxes on the page, and shift focus to the next one, by checking for a keypress event?
Well I solved the problem. I had some javascript running on Key Down to prevent users entering anything other than numbers, which blocked tabbing. Removed it and it worked.

I have a weird situation. I have a panel with 4 textboxes, 2 are read only. I have tab stop set to true and tab index set on panel and two editable textboxes. When running the application, the first textbox never receives focus. I have deleted the textbox and created a new one with a different name, same result. I then reversed the tab order and the other textbox was skipped. for some reason, whichever textbox is set to be hit first when the panel receives focus is completely ignored. I have tried manually setting the tab order and using the tab order wizard both. I have even tried to programmatically set tab index and tab stop just to make sure without any luck. I have several other panels and group boxes on the same form with similar controls, and they all work as expected. I'm running out of ideas, does anyone have any suggestions?
Both the 'Load' button on tabPage2 and the 'Load' Menu Item are running the same code, but as you can see in the demo above when the control is added when tabPage2 is not selected, the column widths shuffle despite it being the exact same code, the exact same control with the exact same content.
I'm not sure how relevant it is to the problem, but the UserControl I am adding looks like this:
Just a tab control with two tabs, a split container on the first tab with a DataGridView in the bottom split panel.
Each 'Load' creates a new tab page, a new user control, adds the user control to the tab page and then adds the tab page to the tab control on tabPage2.
Is there something at play here that I'm not aware of that would make controls render differently depending on their visibility when added?
EDIT: The DataGridView's are using DataGridViewAutoSizeColumnsMode.Fill
It does not have anything to do with the visibility of the tabs when adding the user control. To confirm you can keep the tabPage2 selected and you will see the same behavior as you currently have.
It is the selection and highlights of the tab controls that must be giving that notion. You can try adding around 4 user controls and click between tab2 and tab3 to confirm.
Here is my content page structure:
Listview with 3 columns - label(s.no), Imagebutton(view Record), label(item name).
The Imagebutton has oncommand="view".When clicked, it displays, that row's details in the respective textboxes that are below.
Textbox(itemname)
Textbox(itemcode)
Problem:
When the cursor is in any of the textbox, and I press 'Enter', it is firing the 'View' command event, meaning... I get the details of the first row in the listview, displayed in these textboxes.
I do not want this to happen. Is this behaviour due to the 'DefaultButton' property set somewhere? I tried finding the same in the entire solution but could not.
There are master and content pages and this issue is in every content page.
How can I find out, which control has this property, or what causes this behaviour.
This is the default behaviour of a HTML page.
In ASP.NET, the Panel control has a DefaultButton property that you can set and will change this behaviour. You can put textboxes in a Panel and set the DefaultButton property of the panel.
I have a C# 2.0 WinForms application, looks like this
How to add a button to the upper left corner of TabControl, looks like this?
I am very grateful for your help.
As Kieren Johnstone said it's not possible without creating your own version.. But you could actually just add a tab to the control and catch the on tab changed event. Get the currentTab and if it matches the one that should be your button execute said code.. Then change back to the previous tab.... Its more than possible just a little different.
If you hide the tab it will shift the entire tab control to the left effectively taking out the space you are trying to achieve.. If you do it like what I am saying. And simply add a tab to the tab control. Then use that tab as your button, It will work just like a button does just a little code behind is required to first get the event when the user clicks a tab in the tabControl.
First set the current tab index to the one you want the user to be defaulted to. Store the index value in a variable. Now catch the tabchanged event. If the first tab is selected then the user has clicked your intended button thus meaning you should fire your code that you would have fired from an actual button. Next change the selectedTabIndex to the value contained in the index variable you set earlier. If the first tab is not selected update the value of the index variable set earlier.. This is the simplest way around your problem that I can think of off hand.
I wanna ask for your opinions/ideas about how to automatically add new Textbox when user click on Add button. In my system, there are 2 Textboxes which user need to enter expenses and price respectively. And there's also a ADD button. When they click on it, another two boxes will automatically generate. Before this, I only have 8 Textboxes for expenses and 8 Textboxes for their price. But it looks quite messy for me so i want to make it more tidy. Thank you
You could use a grid and then have a hidden row that has the same input cells as the other rows. When the add button is clicked, have javascript clone the hidden row and then add then show it, and add it to the bottom of the grid.
If a grid isn't right for your UI then do the same thing with just cloning a text box and showing it. It is often easier to just have a single hidden input field with the proper style applied and then clone it, and then remove the display: hidden.
But it looks quite messy for me so i want to make it more tidy.
GridView should be used to make it visibility better and consume space properly.
Assign the DataSource to your GridView
Set the Text boxes in your Footer
When you click the Add Button, Set the Visibility of your Footer "True"
Once user fills the values in Textbox save it and Bind to the GridView.
Repeat Step 4 to iterate the same process next time.
