[ASP.NET] showModalDialog Sample Code
源自：
小鋪上的一則發問
『Double Click 在A頁面上GridView裡的TextBox，Open showModalDialog視窗
提供選取值後，再回填A頁面GridView裡的TextBox』
範例程式碼：
[Page A ]
利用Url將觸發showModalDialog的物件Client ID傳給showModalDialog視窗，如
範例中的source參數，此外showModalDialog第二個參數vArguments給予self，表示
傳入A視窗
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:DBconnStr %>"
SelectCommand="SELECT [code], [name] FROM [bank]"></asp:SqlDataSource>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" onrowdatabound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="code" HeaderText="code" SortExpression="code" />
<asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>public partial class ShowModalDialog : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TextBox tb = e.Row.FindControl("TextBox1") as TextBox;
if (tb != null)
tb.Attributes.Add("ondblclick", "showModalDialog('ShowModalDialog2.aspx?source=" + tb.ClientID + "',self,'dialogWidth:650px;dialogHeight:450px;');");
}
}
}
[Page B]
由於我們已經利用showModalDialog第二個參數vArguments及Url中的source參數
，因此再以window.dialogArguments.document.getElementById 即可把值填回A
頁面中，如範例中的returnval function
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:DBconnStr %>"
SelectCommand="SELECT [name] FROM [city]"></asp:SqlDataSource>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
onrowdatabound="GridView1_RowDataBound" >
<Columns>
<asp:BoundField DataField="name" HeaderText="name" SortExpression="name" />
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="選取" UseSubmitBehavior="False" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void Page_Load(object sender, EventArgs e)
{
string js= @"function returnval(objid, objval) {
window.dialogArguments.document.getElementById(objid).value = objval;
window.close();
}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),"js",js,true);
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Button bt = e.Row.FindControl("Button1") as Button;
if (bt != null)
bt.Attributes.Add("onclick", "returnval('" + Request.QueryString["source"].ToString() + "','" + e.Row.Cells[0].Text + "');");
}
}
