After talking so much, you may not know what I'm talking about ., You will know. Haha.


In the figure, the name can be English or Chinese. When you click the select button in the dialog box, you can return to the parent dialog box.

The Code is as follows:
There are 3 pages in total.
The structure is as follows:

The Default. aspx code is as follows:Copy codeThe Code is as follows: <Head runat = "server">
<Title> pop-up selection window </title>
<Script language = "javascript" type = "text/javascript"> <! --

Function ShowDialog (ch, en, src)
{
Var array = new Array ();
Array [0] = document. getElementById (ch );
Array [1] = document. getElementById (en );

ShowModalDialog (src, array, "resizable: yes;"); // src indicates the pop-up page, where array Passes parameters.
}

// --> </Script>
</Head>
<Body>
<Form id = "form1" runat = "server">
<Table border = "1px">
<Tr>
<Td> </td>
<Td style = "text-align: center;" style = "text-align: center;"> Chinese </td>
<Td style = "text-align: center;" style = "text-align: center;"> English </td>
<Td> </td>
</Tr>
<Tr>
<Td> name: </td>
<Td> <asp: TextBox ID = "chTxtName" runat = "server"> </asp: TextBox> </td>
<Td> <asp: TextBox ID = "enTxtName" runat = "server"> </asp: TextBox> </td>
<Td> <input type = "button" id = "btnChoiceName" value = "select" onclick = "ShowDialog ('chtxtname', 'entxtname', 'frame. aspx '); "/> </td>
</Tr>
</Table>
</Form>
</Body>
</Html>

Javascript pops up modaldialog and is passed to an array. The array contains objects. In this way, multiple values are passed at the same time.
Then I used the framework to solve the problem that the pop-up page GridView. aspx could not pass the value and cache.
The Code of Frame. aspx is also very simple. There is no background code, just an iframeCopy codeThe Code is as follows: <Head runat = "server">
<Title> framework </title>
</Head>
<Body>
<Form id = "form1" runat = "server">
<Iframe id = "gridview" src = "GridView. aspx "src =" GridView. aspx "style =" position: relative; width: 100%; "scrolling =" no "frameborder =" 0 "onload =" document.getelementbyid('gridview').style.height((gridview.doc ument. body. scrollHeight + 20) + 'px' "> </iframe>
</Form>
</Body>
</Html>

This iframe is adaptive. Implemented through the onload event.

Okay. Check the GridView. aspx page.

The Code is as follows:

Copy codeThe Code is as follows: <Head runat = "server">
<Title> GridView </title>
</Head>
<Body>
<Form id = "form1" runat = "server">
<Table>
<Tr>
<Td>
<Asp: TextBox ID = "txtChName" runat = "server"> </asp: TextBox> </td>
<Td>
<Asp: TextBox ID = "txtEnName" runat = "server"> </asp: TextBox> </td>
<Td style = "width: 164px">
<Asp: Button ID = "btnNew" runat = "server" Text = "new" OnClick = "btnNew_Click"/> </td>
</Tr>
<Tr>
<Td colspan = "3">
<Asp: gridView ID = "GridView1" runat = "server" AutoGenerateColumns = "False" DataKeyNames = "ID" OnRowCancelingEdit = "inline" OnRowEditing = "inline" OnRowUpdating = "inline" OnRowDeleting = "inline ""Width =" 359px "BackColor =" LightGoldenrodYellow "BorderColor =" Tan "BorderWidth =" 1px "CellPadding =" 2 "ForeColor =" Black "GridLines =" None "OnSelectedIndexChanging =" unlock ">
<Columns>
<Asp: BoundField DataField = "chName" HeaderText = ""/>
<Asp: BoundField DataField = "enName" HeaderText = "English"/>
<Asp: CommandField ShowEditButton = "True">
<ControlStyle Width = "100px"/>
</Asp: CommandField>
<Asp: CommandField ShowSelectButton = "True"/>
<Asp: CommandField ShowDeleteButton = "True"/>
</Columns>
<EmptyDataTemplate>
No data
</EmptyDataTemplate>
<FooterStyle BackColor = "Tan"/>
<PagerStyle BackColor = "PaleGoldenrod" ForeColor = "DarkSlateBlue" HorizontalAlign = "Center"/>
<SelectedRowStyle BackColor = "DarkSlateBlue" ForeColor = "GhostWhite"/>
<HeaderStyle BackColor = "Tan" Font-Bold = "True"/>
<AlternatingRowStyle BackColor = "PaleGoldenrod"/>
</Asp: GridView>
</Td>
</Tr>
</Table>
</Form>
</Body>
</Html>

On this page, you can create, insert, delete, and update data. When you click Select, the following events are triggered:

Copy codeThe Code is as follows: protected void GridView1_SelectedIndexChanging (object sender, GridViewSelectEventArgs e)
{
String chName = GridView1.Rows [e. NewSelectedIndex]. Cells [0]. Text;
String enName = GridView1.Rows [e. NewSelectedIndex]. Cells [1]. Text;
Response. Write ("<: script language = \" javascript \ ">
Window. dialogArguments [0]. value = '"+ chName +"'; window. dialogArguments [1]. value = '"+ enName +"'; window. close (); <script> ");
}

The above code is the focus of the returned results. window. dialogArguments is actually the array we just passed in. Therefore, it has two objects. These two objects are the objects to be assigned values. Through this sentence, we can achieve our goal.
