Please HELP! Need to access textbox control values within a repeater control

[Darren Smith]

Hi There,

I have a shopping cart app that displays products along with a textbox
(to enter quantity) and an image button to add the item to the
shopping cart. Please explain why my below Button_Click procedure
does not retrieve the value of the textbox where the button was
clicked.

Thanks in Advance,

Darren


Sub Button_Click(s as Object, e as ImageClickEvent Args)
Dim Btn As System.Web.UI.W ebControls.Imag eButton = s
Dim iId as integer
iId=Btn.Command Argument
Response.write (iId)
Dim tb as System.Web.UI.W ebControls.Text Box =
btn.Parent.Find Control("txtVal ue")
Response.write ("TextBox Value=" & tb.Text)
End Sub
-------------------------------------------------------
<form id="frmProducts " runat="server">
<asp:repeater id="rptProducts " Runat="server">
<ItemTemplate >

a href="ProductIn fo.aspx?id=<%# DataBinder.Eval (Container.Data Item,
"prodid") %>"><%# DataBinder.Eval (Container.Data Item, "prodname")
%></a></b></td>

<%# DataBinder.Eval (Container.Data Item, "catdesc") %></td>

<%# formatcurrency( DataBinder.Eval (Container.Data Item,
"retailprice"), 2) %>

member price:&nbsp;<b> <%#
formatcurrency( DataBinder.Eval (Container.Data Item, "memberprice"), 2)
%></b></td>
<asp:TextBox runat="server" width="20" name="txtValue" id="txtValue"
CommandArgument =<%# DataBinder.Eval (Container.Data Item, "prodid") %>
/>
<asp:imagebutto n id=btnAddCart CommandArgument =<%#
DataBinder.Eval (Container.Data Item, "prodid") %> BorderWidth="0"
onclick=Button_ Click Runat="server" ImageUrl="Frame/btnAdd.gif"/>

</ItemTemplate>
</asp:repeater>

Add OnItemCommand=" Repeater_Select " to the repeater

then in the code
public void Repeater_Select ( object source, RepeaterCommand EventArgs e )

{

}
use the CommandArgument property of the imagebutton to pass thorugh the information you require..

if you need multiple values then do the following
CommandArgument ='<%# DataBinder.Eval (Container,"Dat aItem."+ ITEMONE +","+ ITEMTWO") %>'

then just split on that..
string res = e.CommandArgume nt.ToString();

string delimStr = ",";

char [] delimiter = delimStr.ToChar Array();

string[] vals = res.Split(delim iter);

string s = vals[0].ToString();

string x = vals[1].ToString();

Hi Darren,

Thanks for your prompt reply, most appreciated.

public void Repeater_Select ( object source, RepeaterCommand EventArgs e )

{

}

Does the Repeater_Select Sub remain empty?

commandargument ='<%# DataBinder.Eval (Container,"Dat aItem."+ ITEMONE
+","+ ITEMTWO") %>'

Is the above commandargument added to the imagebutton?

string res = e.CommandArgume nt.ToString();
string delimStr = ",";
char [] delimiter = delimStr.ToChar Array();
string[] vals = res.Split(delim iter);
string s = vals[0].ToString();
string x = vals[1].ToString();

Is the above code placed in the Repeater_Select or the ImageButton
On_Click routine?

Thanks,

Darren

Sorry, one more thing...

At which point does the routine pass the value of the quantity textbox?

I should have put this in before...
Here is an example..

<asp:Repeater Runat="server" ID="JobPosts" OnItemCommand=" Repeater_Select ">
<p>
<asp:imagebutto n
CommandArgument ='<%# DataBinder.Eval (Container,"Dat aItem."+ JR.Core.Data.Jo bData.FLD_JOB_I D) %>'
CommandName='Ed itJob'
id="EditJob" onmouseover="th is.src ='../Images/editover.gif'"
onmouseout="thi s.src ='../Images/editnorm.gif'" Runat="server"
ImageUrl="../Images/editnorm.gif"
AlternateText=" Edit Job">
</asp:imagebutton >
</p>
</asp:Repeater>
When the imagebutton is clicked it will push the event up to the repeaters onitemcommand
public void Repeater_Select ( object source, RepeaterCommand EventArgs e )
{
///<summary>
/// THis is when a button is selected from inside the repeater.
///</summary>

// Get the JobID and then send the user to the correct page.
string JobID = e.CommandArgume nt.ToString();

Session["JobID"] = e.CommandArgume nt.ToString();

if (e.CommandName. ToString() == "JobResults ")
{
Response.Redire ct("JobResults. aspx");
}
else if(e.CommandNam e.ToString() == "EditJob")
{
Response.Redire ct("EditJob.asp x");
}
else if (e.CommandName. ToString() == "ArchiveJob ")
{
// this is used as the CommandArgument passess 2 values through as s delimtered string eg. val1,val2

string res = e.CommandArgume nt.ToString();
string delimStr = ",";
char [] delimiter = delimStr.ToChar Array();
string[] vals = res.Split(delim iter);
string s = vals[0].ToString();
string x = vals[1].ToString();
int jobID = Convert.ToInt32 (s);
int status = Convert.ToInt32 (x);
JobManager man =new JobManager();
man.UpdateJobSt atus(jobID,stat us);
}
}
