need help in opening a popup window

HI Again,
I have another query which could be simple but i am not able to resolve it. I need to have a button or link in my page which needs to open a popup window and need to be able to send a variable attached to the link which comes from a database.

the url goes like this

Code:

---



'list.aspx?id="+Databinder.Eval(Container.DataItem, "Id")'

---

The code is in a <asp:Repeater>. I can have a <asp:button> control and call a c# function onclick event like this

Code:

---

void popup(object sender, System.EventArgs e){
buttonid.Attributes.Add("onclick","window.showModaldialog('url','','height:px, width:px') etc
}

---

1. how do i access the id from the database in this code
2. how do i attach a variable to the url
3. is there a better way to do this, like link or anyother instead, but there is no onclick event in the hyperlink tag so i can't say 'window.open there? Any other suggestion?

THanks

Code:

---

      //page load of list.aspx with querystring id=..
      protected void Page_Load(object sender, EventArgs e) {
          string url = "navigateUrl.aspx?id=" + Request.Querystring["id"]; //or get the id somewhere else from
         
          string popup = string.Format("window.showModaldialog('{0}','','height:px, width:px');", url);

          button1.Attributes.Add("onclick", popup);
      }

---

THanks for the reply.
THe id is coming for the database not from previous page.

Code:

---


<asp:repeater id="myview">
<....
>
<tr>
//so i add a hyperlink I can pick up the value from the database using
<td><asp:hyperlink navigateurl='<%# "nextpage.aspx?folder="+DataBinder.Eval(Container.DataItem, "ID")%>' ........




</td>
</tr>
....
</asp:Repeater>

---

this opens a new full IE window, i want a popup. If i try as a button and doesn't seem to get it right.

Code:

---


<asp:repeater id="myview">
<....
>
<tr>
//so i add a hyperlink I can pick up the value from the database using
<td><asp:button onclick='window.open(<%# "nextpage.aspx?folder="+DataBinder.Eval(Container.DataItem, "ID")%>', height,width)  ........



</td>
</tr>
....
</asp:Repeater>

---

or try like this

Code:

---


/or
<td><asp:button onclick="popup">

//c# code in the same aspx page
void popup(object sender, System.EventArgs e){


//how do i get the value from the database here, there is no value attribute to a button
//which i call to differentiate different button that are clicked and where do i add the attribute.

Btn.Attributes.Add("onclick", "window.showModalDialog('target.aspx','', 'dialogHeight: 200px; dialogWidth: 300px;')");

}

---

Hope i make sense now.

I tried everything and anything but the only way i could make it work is

Code:

---


<input type="button" onclick="javascript:window.open('target.aspx?id=<%#DataBinder.Eval(Container.DataItem,"id") %>','','height=350,width=350');"  value="-">

---

even the <a href> doesn't work if i add the onclick code, and leaves the href="#", it tries to open a new window and then opens the popup.

<asp> tags i always get the server tag is not well formed, infact if i try to include runat="server" in the above code, i get the same error message.

I am not sure if it's a good idea to mix <asp:> tags and standard html tags, i need to test this in several system to make sure it works.

Any suggestion is welcome.

If you are really keen to stick with asp.net server controls you could have an anchor inside your repeater and add the href attribute through code in the item data bound procedure. You will have to include a hidden field in your repeater though.

If your repeater is something like

Code:

---

        <asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
        <ItemTemplate>
            <asp:HiddenField ID="myh" value='<%#DataBinder.Eval(Container.DataItem,"id") %>' runat="server" />
            <a id="mya" runat="server" />
        </ItemTemplate>
        </asp:Repeater>

---

then the Repeater1_ItemDataBound procedure would be

Code:

---

    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            HiddenField h = (HiddenField)e.Item.FindControl("myh");
            HtmlAnchor a = (HtmlAnchor)e.Item.FindControl("mya");
            a.HRef = "javascript:window.open('target.aspx?id=" + h.Value +  "','','height=350,width=350')";
            a.InnerText = h.Value;
        }
    }

---

This would open a pop up with target.aspx when you click on the link.

Warm Regards,
