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.

hi

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.

Can any one plzzzz let me know the reasons opf session log out whether the ASP.Net state service is running or not, plz reply me ASAP.
|
|
|
|
|
1. sessionTimeout
2. changes made in web.config/machine.config
3. Reset IIS
4. aspnet work-processor is overloaded.
5. Application shutdown
|
|
|
|
|
You probably missed one thing if the user is not interactime for a specific period then also there will be session timeout.
