Hi, I have a project with 2 groups of buttons and I need assign to event on click to 1 group same piece of code and to 2 group another code. Solving it some component like GroupBox or someone?

Hi,
you can use the same Click handler for more than one Control.
And if need be, cast sender to the right Control type to find out which Control fired the Click event.
|
|
|
|
|
Can you write that in code please? I need something like this to more powerful code:
NOW:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
}
private: System::Void button2_Click(System::Object^ sender, System::EventArgs^ e) {
}
...
Future something like this:
button 1-10_Click
|
|
|
|
|
replace button2_Click by button1_Click everywhere;
replace button3_Click by button1_Click everywhere;
replace button4_Click by button1_Click everywhere;
replace button5_Click by button1_Click everywhere;
replace button6_Click by button1_Click everywhere;
replace button7_Click by button1_Click everywhere;
replace button8_Click by button1_Click everywhere;
replace button9_Click by button1_Click everywhere;
replace button10_Click by button1_Click everywhere;
everywhere also includes code autogenerated by Visual Studio.

Thank you, it works. But I have got still one little problem.
I need take Button1->Text, ..., Button10->Text so I have something like that
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
textBox1->AppendText(buttonX ->Text);
}
How to change X?

Hi,
as I told you before, you can
cast sender to the right Control type to find out which Control fired the Click event.
In your case, cast to Button, then use its Text property.
|
|
|
|
|
can you write it in code please?
|
|
|
|
|
if you show your code, and specify its symptoms, CP members will help and pinpoint the problem(s).
|
|
|
|
|
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
textBox1->AppendText(System::Windows::Forms::ButtonBase::Text);
}
I do this code, but it still needs System::Windows::Forms::ButtonBase::Text as a static.
I think I follow your definition - you can say that in values sender and e is everything what can we need.
|
|
|
|
|
you still need to take "sender", cast it to a Button and take its Text. 
|
|
|
|
|
textBox1->AppendText(this->ActiveControl->Text);
Yipee! Fairness still exists  Thank you so much

The other answer posted to this thread will work perfectly. Another option would be to create a new usercontrol for the groupbox control collection.

Hello all
I have a TabControl which has some TabPages with controls

DataBinding cannot find a row that is suitable for all bindings.
Note: I have some DateTimePickers on the form which I think the problem in.

Hi,
Iam new to c#.net.Iam using windows web browser which automatically loads url from the database.It is loading allthe urls from database but i cant able to do anything in between (for eg:i need to send some data to a particular site before it navigates to another site).I am using visual studio c#.net.
My code looks like this:
SqlConnection mycon = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\hm67951\Desktop\WebBrowser\WebBrowser\webbrowser.mdf;Integrated Security=True;User Instance=True");
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter("select * from urlnames", mycon);
da.Fill(ds, "urlnames");
cboURL.DataBindings.Add("Text", ds, "urlnames.url");
btnclick();
MessageBox.Show("pageloaded");
for (int i = 0; i < ds.Tables["urlnames"].Rows.Count; i++)
{
CurrencyManager cm = (CurrencyManager)this.BindingContext[ds, "urlnames"];
long rowposition = (long)cm.Position;
if (cm.Position < cm.Count - 1)
{
cm.Position++;
//this.BindingContext[ds, "urlnames"].Position++;
if (cboURL.DataBindings["Text"] != null)
{
cboURL.DataBindings.Remove(cboURL.DataBindings["Text"]);
}
cboURL.DataBindings.Add("Text", ds, "urlnames.url");
btnclick();
MessageBox.Show("pageloaded");
}
If i remove Messagebox.show option it is showing only the last url which is loaded from the database.
Thanks in advance.

Hello,
could anyone solve my problem. I have application working with MSSQL Server: there is one table "goods" (id, name) and another one - "info" (id, idgood1, idgood2, info), where idgood1 and idggod2 - foreign keys. That is an example of what I want.
"Goods" Table:
id | name
---------
23 | foo1
24 | foo2
25 | foo3
"Info" Table:
id | idgood1 | idgood2 | info
-----------------------------
10 | _____23 | _____24 | inf1
11 | _____23 | _____25 | inf2
12 | _____24 | _____25 | inf3
I want to see in DataGridView such structure (first row - row header, first column - column header):
____ | foo1 | foo2 | foo3
--------------------------
foo1 | ____ | inf1 | inf2
foo2 | ____ | ____ | inf3
foo3 | ____ | ____ | ____
I select data from two tables ("goods", "info") in appropriate DataTable instances: GoodsDataTable and InfoDataTable. Then I CREATE (dynamically) one more DataTable instance - VisualDataTable, which is filled according to my needs. Then I put VisualDataTable into DataSet, DataSet into BindingSource, and, finally, BindingSource into DataGridView. It's working. Until I want to update something!
I tried to call SqlAdapter's Update method as for InfoDataTable as DataSet. But nothing happens.
In general, how should I update data in case when "visual" part of DataGridView and database structure are different..?
Another words, I take data from database, and put data into database with one table, and I edit data with another table.

hi...
i hve a mdi form and i added 4 buttons in the mdi form. these buttons are shortcuts of child forms. when i open the child forms , these buttons are showing front, ie, the child form is behind these buttons... can any one help to sortout this..
Tnks in advance..

Their is a chance that you can call SendToBack on the buttons to allow the forms to be in front, but I sort of doubt it just because of how the MDI form is used. Why not just a toolbar in the MDI parent for the form switching.

Hi Everyone
I have upper level framework that needs to be notified when the user has selected text in a regular textbox.
There doesn't seem to be a event to signals that the selected text value has changed.
Any suggestions other then a timer that polls the control?
Thanks
|
|
|
|
|
I think your right, there is no event for selected text, you would have to use key/mouse events or possibly on leave

The quickest way to implement this would be with the MouseUp event. Try this approach:
private int selectedTextLength = 0;
private int selectionStart = 0;
private void textBox1_MouseUp(object sender, MouseEventArgs e)
{
if (selectionStart != textBox1.SelectionStart ||
selectedTextLength != textBox1.SelectionLength)
{
selectionStart = textBox1.SelectionStart;
selectedTextLength = textBox1.SelectionLength;
//notify framwork...
}
}
Cheers!

Hi,
When i assign a text to the datagrid cell that contains tabs "\t", the tab is ignored when the cell is out of focus or not in edit mode.
example:
myDataGridView[columnIndex, rowIndex].Value = "My\tText";
when the cell is out of focus or not currently edited, the displayed text is : "MyText".
when the cell is entered to edit text, the displayed text is : "My Text".
How do i force the cell to always show the text with the tabs, even in read only mode?
Thanks.
