Highlight text in a dynamic textbox

Posted By:      Posted Date: October 13, 2010    Points: 0   Category :ASP.Net

 Hi, I have a dynamic textbox appearing in a gridview on the row editing function. I have the following code to set the focus tot he textbox:

GridView1.EditIndex = e.NewEditIndex

This works fine, but I would now also like to select the data in the textbox so the user does not have to select the text before typing, they can just type straight away.

I have been trying to use:

txtTargetAmount1.SelectionStart = 0
txtTargetAmount1.SelectionLength = txtTargetAmount1.Text.Length

but this does not work.

Any ideas?

Textbox text populated by Session Variable wont update into SQL with new text


Hi everyone, I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Why would the button click cause the textbox refresh with the text from the pageLoad before updating the data source?

TextBox shows binding source text when window load, so why not with the ComboBox?

How can I get a ComboBox to show the binding source value when my window opens?  I have been searching all day for a solution to this, but cannot find anything.  So I have created a sample project to demonstrate my problem.  Below is a Vehicle class, very simple, two members Category and Make.  Category is an enumeration, Make is a string. namespace ComboExample { public class Vehicle { // Constants and enumerations public enum eCategory { Road, Air, Sea } // Attributes public eCategory Category { get; set; } public String Make { get; set; } // Construction public Vehicle(eCategory Category, String strMake) { this.Category = Category; this.Make = strMake; } } } Here is the C# for the MainWindow.  A new Vehicle object is created as a member.  In the constructor I set a data-provider in the XAML to this Vehicle object.  There is a button event for showing the values of the controls and objects so I can check the binding. namespace ComboExample { // Interaction logic for MainWindow.xaml public partial class MainWindow : Window { // Attributes Vehicle m_Car = new Vehicle(Vehicle.eCategory.Road, "BMW"); // Construction public MainWindow() { InitializeComponent(); // link data-p

Textbox Text Property

I am new to VB and I have read that if I don't explicity cast variable types it will eat up performance. I have been casting certain objects, such as values from data readers, but I was wondering if the object has a property that says it is a string, like the textbox "Text" property, if I need to still cast that as a string.   Right now my code says "txtSearch.Text" but should I be using "txtSearch.Text.ToString()"?   Thanks in advance for the help!

Dynamic Textbox List Control - problems refreshing


Ive been stuck on this one for a month:

So I have a custom control that has a list of textboxes, and a button that will dynamically add a new textbox to the list.

 So I have an addTextbox() function, that will do something like

TextbBox t = new TextBox()

 then I add it to the page.  So adding a new textbox works fine, but I have values that I want to put into each textbox and upon each page load, the values get replaced.  What I need to do is get the textboxes from the viewstate so I can use their values for other textboxes, but since they are created anonymously, im not sure how I can do that.  I tried to get the unique name and put all of them into an arraylist, then upon the next page load, load the names from the list, but the unique name isnt unique.  Thanks
