Update panel with Gridview control

A

Alex. O. Koranteng

I am getting the following error mesage from the label control on my aspx
files.

Error creating control:labeid not specified and here is the code below
I have two grids. The first grid shows a gridview with no ajax
functionality. The second grid shows ajax functionality. Any suggestions will
be appreciated. IF you need more info, I will send you a zipped file of the
solution.

<body>
<form id="frm" runat="server" >
<div style="margin-left:35px">
<asp:ScriptManager ID="scriptManager" runat="server" />
<asp:SqlDataSource
ID="sqldsCustomers" runat="server"
SelectCommand="select customerid, companyname, contactname,
contacttitle from dbo.[customers]"
SelectCommandType="Text"
ConnectionString="todo"
CancelSelectOnNullParameter="true" />

<p style="background-color:AliceBlue; width:95%">
Example of two customer GridViews, the top one is not ajax enabled
and sort or paging will cause the entire page to refresh. The bottom
GridView is ajax enabled and does not cause the complete page to rerender<br

Hi Alex,

Regarding on the problem you mentioned, I've performed some test with the
aspx markup you provided. Since you haven't provided script functions(and I
haven't your database), so I modified it to use my own database connection
and scription function. Except these changes, the page can work correctly.
Here is the modified markup I used for test.

You can have a look at my page and compare with yours to see whether there
is anything different. If necessary, I can also send you my test page.

Steve,

Thanks for all your code suggestions. I have added your code and just made
minor changes to jscript functions and the CustomerNoAjax.aspx page is
working just as expected. However, when I run the Triggers11.aspx page, I get
the error below. My goal is make the search button work without hard coding
the orderid as the author had done. Any suggestions will be admired. I will
email you my current working version. Also I am getting this minor error
label:ID property is not specified which I do not see why because in my
solution, I ahve defined the id property

Hi Alex,

I've checked the project you sent me. Yes, I got the error when tried
running "trigger1.aspx". Based on the error message and callstack, I found
that the error occured during the database connection construction, see
callstack below

[ArgumentException: Format of the initialization string does not conform to
specification starting at index 0.]
System.Data.Common.DbConnectionOptions.GetKeyValuePair(String
connectionString, Int32 currentPosition, StringBuilder buffer, Boolean
useOdbcRules, String& keyname, String& keyvalue) +1242
System.Data.Common.DbConnectionOptions.ParseInternal(Hashtable
parsetable, String connectionString, Boolean buildChain, Hashtable
synonyms, Boolean firstKey) +126
System.Data.Common.DbConnectionOptions..ctor(String connectionString,
Hashtable synonyms, Boolean useOdbcRules) +102
<<<<<<<<<<<<<<<<

So I checked the connectionString of the SqlDataSource control used on that
page and found that you haven't specified the correct connectionString
expression. Here is the original content:

======================
<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid"
SelectCommandType="Text"
ConnectionString="todo"
OnSelecting="SqldsOrderDetails_Selecting"
CancelSelectOnNullParameter="true" />

<p style="background-color:AliceBlue; width:95%">
Example linking the UpdatePanel to a button outside of the panel
that triggers the asynchronous post-back using the AsyncPostBackTrigger<br
/>
</p>
===================

You need to change the connectionString to the correct one(pointing to
NorthWind database), like below:
==========================

<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid"
SelectCommandType="Text"
ConnectionString="<%$
ConnectionStrings:NorthwindConnectionString %>"
OnSelecting="SqldsOrderDetails_Selecting"
CancelSelectOnNullParameter="true" />

<p style="background-color:AliceBlue; width:95%">
Example linking the UpdatePanel to a button outside of the panel
that triggers the asynchronous post-back using the AsyncPostBackTrigger<br
/>
</p>
=============================

Then, the page starts working.

Hope this helps.

Steve,

I have implemented your code changes and the search button is working for
orderid# entered. However, How do I tweak my code such that all records are
returned when no orderid# is entered. It looks like the change has has to be
at this line: and maybe adding & "*" but I am not sure. Any suggestions.

Thanks for your followup Alex,

Glad to hear that you've got further progress on this.

Regarding on your new questions(deal with empty input parameter of the
TextBox), there are two ideas come up to my mind:

1. You can put the GridView into a panel ,and another GridView(within a
separate panel) on the page. And you can make either one of them visible
depend on the Value in TextBox(whether it is empty or not). And one of the
GridView will alway manually query all the records from table. Also, to
improve performance, you can only perform databinding manually(for that
gridview which display all records) when the TextBox is empty.


2. change the SQL select statement of the SqlDAtaSource control you used.
Add an additinal parameter to control whether it will return all the
records or not:

e.g.

=============================
<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid OR 1 = @display_all"

.................... />



protected void SqldsOrderDetails_Selecting(object sender,
SqlDataSourceSelectingEventArgs args)
{
args.Command.Parameters.Add(new
System.Data.SqlClient.SqlParameter("@orderid", this.txtOrderID.Text));

System.Data.SqlClient.SqlParameter parameter = new
System.Data.SqlClient.SqlParameter("@display_all",
System.Data.SqlDbType.Bit);
if (string.IsNullOrEmpty(txtOrderID.Text.Trim()))
{
parameter.Value = 1;
}
else
{
parameter.Value = 0;
}

args.Command.Parameters.Add(parameter);
}
==============================

So I checked the connectionString of the SqlDataSource control used on that

expression. Here is the original content:

======================
<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid"
SelectCommandType="Text"
ConnectionString="todo"
OnSelecting="SqldsOrderDetails_Selecting"
CancelSelectOnNullParameter="true" />

<p style="background-color:AliceBlue; width:95%">
Example linking the UpdatePanel to a button outside of the panel
that triggers the asynchronous post-back using the AsyncPostBackTrigger<br
/>
</p>
===================

You need to change the connectionString to the correct one(pointing to
NorthWind database), like below:
==========================

<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid"
SelectCommandType="Text"
ConnectionString="<%$
ConnectionStrings:NorthwindConnectionString %>"
OnSelecting="SqldsOrderDetails_Selecting"
CancelSelectOnNullParameter="true" />

<p style="background-color:AliceBlue; width:95%">
Example linking the UpdatePanel to a button outside of the panel

Then, the page starts working.

Thanks for all your code suggestions. I have added your code and just made

working just as expected. However, when I run the Triggers11.aspx page,

Thanks for your followup Alex,

Glad to hear that you've got further progress on this.

Regarding on your new questions(deal with empty input parameter of the
TextBox), there are two ideas come up to my mind:

1. You can put the GridView into a panel ,and another GridView(within a
separate panel) on the page. And you can make either one of them visible
depend on the Value in TextBox(whether it is empty or not). And one of the
GridView will alway manually query all the records from table. Also, to
improve performance, you can only perform databinding manually(for that
gridview which display all records) when the TextBox is empty.


2. change the SQL select statement of the SqlDAtaSource control you used.
Add an additinal parameter to control whether it will return all the
records or not:

e.g.

=============================
<asp:SqlDataSource
ID="sqldsOrderDetails" runat="server"
SelectCommand="select * from dbo.[order details] where
orderid=@orderid OR 1 = @display_all"

.................... />



protected void SqldsOrderDetails_Selecting(object sender,
SqlDataSourceSelectingEventArgs args)
{
args.Command.Parameters.Add(new
System.Data.SqlClient.SqlParameter("@orderid", this.txtOrderID.Text));

System.Data.SqlClient.SqlParameter parameter = new
System.Data.SqlClient.SqlParameter("@display_all",
System.Data.SqlDbType.Bit);
if (string.IsNullOrEmpty(txtOrderID.Text.Trim()))
{
parameter.Value = 1;
}
else
{
parameter.Value = 0;
}

args.Command.Parameters.Add(parameter);
}

Steve,

I have implemented your code changes and the search button is working for
orderid# entered. However, How do I tweak my code such that all records are
returned when no orderid# is entered. It looks like the change has has to be
at this line: and maybe adding & "*" but I am not sure. Any suggestions.
