tabcontrol中每个标签页上的文本框

Question

I am new to c#. I have a tab control with 3 textboxes. On button click I add a new tabpage with clone textbox.

code:

TabPage tpQueriesFree = new TabPage("Queries" + (tabCQueries.TabCount + 1).ToString());
tpQueriesFree.UseVisualStyleBackColor = true;
tbSqlProviderName.Location = new System.Drawing.Point(111, 4);
tbSqlProviderName.Name = "tbSqlProviderName" + (tabCQueries.TabCount + 1).ToString();
tbSqlProviderName.Size = new System.Drawing.Size(364, 20);
tbSqlProviderName.TabIndex = 1;
tbSqlProviderName.Text = "System.Data.SqlClient";
tpQueriesFree.Controls.Add(lblSQLProvideName1);
tpQueriesFree.Controls.Add(tbSqlProviderName1);

I added a new button for writing to the xml file. When I click the button I need to write tbtbSqlProviderName for each tabpage with:

xml.WriteElementString("SqlConnectionString", tbSQLConnString.Text);

what do I need to do to get

xml.WriteElementString("SqlConnectionString", tbSQLConnString.Text); 

for each tabpage?

Use a foreach , like so:

foreach (TabPage tp in tabControl1.TabPages)
{
    foreach (TextBox tb in tp.Controls)
    {
         xml.WriteElementString("SqlConnectionString", tbSQLConnString.Text);
    }
}

Is this what you wanted?

Glad to help.
