Hi All! I want to know how can I change the value of a text box on Page1 from Page2 by clicking on a button on page2 without using querystring,session or posting the form back. It may sound silly but I've seen this happened myself. Even if it is possible through javascript or asp.net
Many thanks

If one page is a popup window then it is possible with javascript.
opener.window.document.getElementById('yourTextboxID').value = 'yourValue'

I'd like to see an example of this, especially the no postback option

You didn't mention popup in your original question.

What you need is a reference to the window of the page that you want to access.
If Page2 is a window opened by Page1, you get a reference to the window containing Page2 as the return value of the call to the window.open method. You get a reference to Page1 by using window.opener.
Let's say that the variable win contains a reference to the window, then you can access the document property of the window, and use that to access it's content. Example:
win.document.getElementById('SomeControl').value = 'Hello world!';
In some cases it might not work well to directly access elements of a different page. Then you can call a function in the page that accesses the element:
win.document.someFunction('Hello world!');
function someFunction(text) {
document.getElementById('SomeControl').value = text;
}

Hello
I need a Help from the developers ......
i need to do a thing which look like simple but i can't find the way to do that .. so please update me if anyone knows this.
i am using a variable which store the name of the control as u can say :
string storecontrol = "textbox1";
and i need a method so that i can give only
storecontrol.text
and access the text in the corresponding textbox...as
console.WriteLine(storecontrol.Text);
and it will print the value of the textbox1.Text
If anyone knows this , then reply it..
Dotnetjunkie.....

If you know the parent of the control, you can use the FindControl method to locate the control.

b { font-weight: normal; }

If you can't use findparent, you could use reflection [assuming you are working in code behind]:
public void foo()
{
string TextBoxName ="txtBar";
TextBox requiredBox = GetBoxByName(TextBoxName);
requiredBox.Text = "New Value";
}
protected TextBox GetBoxByName(string name)
{
Type t = this.GetType();
FieldInfo fi = t.GetField(name);
return fi.GetValue(this) as TextBox;
}
I've not tested this properly, so don't be surprised if it doesn't work. If you want to specify which property you want (in your example .Text) you could create a GetProperty method running along the lines of "GetBoxByName" which uses reflection to find the property you want.

You can't do that.
What you can do is to create Javascript code that will recreate the array. For an example an array of integers:
int[] values = new int[] { 1, 2, 3, 4 };
StringBuilder code = new StringBuilder();
bool first = true;
foreach (int v in values) {
code.Append(first ? "var values = [" : ", ");
first = false;
code.Append(v);
}
code.Append("];");
Page.ClientScript.RegisterStartupScript(this.GetType(), "ValuesArray", code.ToString(), true);

You can use javascript confirm for the same purpose.

Actually when a user clicks on the delete button, it is not at all required to go to the server and show the confirmation message. Inspite you can use javascript for that it will remain there in client side only. And suresh has given the complete sample code for that.

function confirm_delete()
{
if ( confirm( "Are you sure you want to delete the Record?") == true )
return true;
else
return false;
}
try this javascript in ur html view code
and
write this code in ur itemcreated event of grid
try
{
if ( e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem )
{
_myButton.Attributes.Add("onclick", "return confirm_delete();");
}
}

Your message box - it might appear on your web server...
|
|
|
|
|
You are correct in sense that the code is executed on the server, so if a message box would appear, it would appear on the server.
The ASP.NET environment is specified as not having any user interface, though, so an attempt to display a message box will cause an exception.
