Questions about dynamically loading controls ....

This is the code on the page: 1
String idx = "";

Idx = request. querystring ["idx"];

C_edititem = (edititem) page. loadcontrol ("productbarcodecontrols/edititem. ascx ");



C_edititem.pk_id = idx;



This. web_contaner.controls.add (c_edititem );

C_edititem.setrunningtype (actiontype. updatedbarcodeitem );

Here is the runingtype Code 2 in the user control.

Public void setrunningtype (string Rtype)

{



Switch (Rtype)

{

Case actiontype. updatedbarcodeitem:

Setlabletotext ();

Code_txt.editenable = false;

Action_pal.visible = true;

Add_btn.visible = false;

This. bindlist ();

Break;

Case actiontype. viewbarcodeitem:

Action_pal.visible = false;

This. bindlist ();

Break;

}

}

Here is code 3 for setting data.

Datarow ROW = This. mycode. getbarcodebyidx (this. pk_id );

Code_txt.text = row [barcodedata. code_field]. tostring ();

Partno_txt.text = row [barcodedata. partno_field]. tostring ();

Updatepartno_txt.text = row [barcodedata. newpartno_field]. tostring ();

Standardpartno_txt.text = row [barcodedata. standpartno_field]. tostring ();

Customer_txt.text = row [barcodedata. customer_field]. tostring ();

Status_rdb.selectedvalue = row [barcodedata. status_field]. tostring (). Trim (). tolower ();

Remark_txt.text = row [barcodedata. remark_field]. tostring ();


Labeltype_txt.text = row [barcodedata. labeltype_field]. tostring ();

Labledescritiop_txt.text = row [barcodedata. labeldescription_field]. tostring ();

Description_txt.text = row [barcodedata. description_field]. tostring ();

Updatedesc_txt.text = row [barcodedata. newdescription_field]. tostring ();

Here is code 4 updated after pressing update.

Datarow ROW = This. mycode. getbarcodebyidx (this. pk_id );

Row [barcodedata. partno_field] = partno_txt.text.trim ();

Row [barcodedata. newpartno_field] = updatepartno_txt.text.trim ();

Row [barcodedata. standpartno_field] = standardpartno_txt.text.trim ();

Row [barcodedata. customer_field] = customer_txt.text.trim ();

Row [barcodedata. status_field] = status_rdb.selectedvalue;

Row [barcodedata. remark_field] = remark_txt.text.trim ();


Row [barcodedata. labeltype_field] = labeltype_txt.text.trim ();

Row [barcodedata. labeldescription_field] = labledescritiop_txt.text.trim ();

Row [barcodedata. description_field] = description_txt.text.trim ();

Row [barcodedata. newdescription_field] = updatedesc_txt.text.trim ();


Row [barcodedata. lastmodify_field] = system. datetime. now;


Row. acceptchanges ();

I click the update button to update the data order by tracking

1-2-3-4

Here is a logic error:

That is, step 1 should not be executed.

According to my ideas,

The data is not updated because the data is rebound in step 3.

However, the result is the opposite: the data is updated.

The normal logic should be

1-2-4

Although I don't know how Microsoft handles it, I have rewritten two steps according to the correct logic.
Case actiontype. updatedbarcodeitem:

Setlabletotext ();

Code_txt.editenable = false;

Action_pal.visible = true;

Add_btn.visible = false;

If (! Ispostback)

This. bindlist ();

Break;

Indicates that data is rebound when page load is not performed during post.
