Is this posible?

I have a 2 Repeaters in place on my WebForm.

What I would like to do is be able to select a record on the first repeater
(contained within a ASP:Panel) to reveal the details of the record in the
second Repeater (Contained in ASP:Panel2).

What would I use to accomplish this? I am using stored procedures from SQL
to facilitate the queries, I just can't seem to capture the selected item
or ID of the record selected in the first repeater.

Thank you for your thoughts.

Sincerely,

Tim

You can put a button inside the repeater, then set it's CommandName="DoSomething".
Then handle the Repeater's ItemCommand event -- this is called when a button
inside the repeater is clicked. You can make sure it's your button by checking
the e.Item.CommandName == "DoSOmething" (this is the same as your CommandName
specified above). So the problem is then to know what row you're working
with, or more specifically, what's the primary key of your row in the DB
that you should load into the other repeater. So in your Button, you can
also fill in the CommandArgument in your ItemTemplate to data bind to the
PK column from your database. This is presented to you in the ItemCommand
event as e.Item.CommandArgument. This can then be used to populate your second
Repeater.

Brock,

Thank you very much for your time and thoughts. I am starting to
understand a bit more but can't seem to get the command to fire.

Here is my linkbutton control code:
<asp:LinkButton Runat="server" ID="detail" CommandName="get_detail"
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID")%>'>
<%# DataBinder.Eval(Container.DataItem, "Cust_Name")%>
</asp:LinkButton>

Here is the code behind:
private void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
{
Summary.Fill(sum_hscti1);
DataBind();
Panel1.Visible = true;
Panel2.Visible = false;
}
}

private void get_detail(object sender,
System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
Panel1.Visible = false;
Panel2.Visible = true;
}

The is placement of the Panel code in the IsPostBack the problem? Is the
postback causing the Panel condition to reload first case instead of the
case contained in the get_detail command?

Thank you again for your time.

Sincerely,

Tim

Brock,

I have made some modifications that have resolved the Panel issue however,
I am still

on how to wire the linkbutton control in code behind so
that the id value of the record is retained and used in the query to
populate the second Panel.

Here is my link button control code:
<asp:LinkButton Runat="server" ID="detail" CommandName="get_detail"
CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID")%>'>
<%# DataBinder.Eval(Container.DataItem, "Cust_Name")%>
</asp:LinkButton>

Here is my code behind:
public void get_detail(object sender,
System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
if (e.CommandName == "get_detail")
{
Panel1.Visible = false;
Panel2.Visible = true;

Full.Fill(full1);
Comments.Fill(cmnts1);
DataBind();
}
}

I know there is a whole section missing here that is needed to bind the id
value of the control to the dataset for the second panel, but I can't
decipher or locate any code examples to help me resolve this issue.

Can you expand upon this for me please.

Thank you for your time.

Sincerely,

Tim

Ok, so I have made some progress on this but have come to a barrier I can't
seem to get over. I can now get the variable result for the id chosen in
the repeater but for some reason, I can't get the details of the summary
record chosen.

Here is my code behind:
private void Repeater1_ItemCommand(object source,
System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
//Gets the value of the record chosen by the linkbutton
int ID = Convert.ToInt32(e.CommandArgument);
// Fills the dataset for geting the full details
Full.Fill(full1);

}

Public void get_detail(object sender,
System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
if (e.CommandName == "get_detail")
{
Panel1.Visible = false;
Panel2.Visible = true;

Comments.Fill(cmnts1);
DataBind();
}
}

Can somone help me figure out the missing link (sorry, bad pun).

Thank you.
Tim
