DAL means Data Layer.

We use this just to separate the Data blocks from presentation layer, so that data manipulation could be made easily manageable.

AFAIK, It will not involve any performance issue.

Hi all,
I am designing my program like this. I am having a text box, button and a grid view on my page. When i entered some value in text box and click on button the value is binding to grid view. In the grid view i am having only one field as Name and option as select. When i click on select i am displaying the corresponding user in the text box. What i need is if i edit the text on the text box and click on the same button again the value should replace the old one.

Example

TextBox -----------
Button
Gridview

Name

Dora select

Xyz Select

When i click on select at xyz i am displaying it in text box. If i would like to replace it with some name like ABC what to do.. Please help me..

Problem with GridView: How to change the text of Button in a GridView Cell ?

29-Oct-09 2:01

Yes ... It is trivial... First of all let me know are you storing the data into database ?

If the data is in the database, just update the value when user clicks on the button after updating the data, and rebind the Gridview to reflect the update.

Re: Problem with GridView: How to change the text of Button in a GridView Cell ?

How can I show additional button in a gridview cell based on another cell value.I am using asp.net and c#.

I have ON or OFF values in a GridView cell. Based on this value I want to show a button (opposite Toggle (OFF/On) correspondingly) in another cell.

This is my code.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.Cells[2].Text== "0")
e.Row.Cells[2].Text = "OFF";
else
e.Row.Cells[2].Text = "ON";
}

please help.
Thank You

Are you looking for UnBound TemplateField ?

Simply add

<asp:TemplateField HeaderText="Mode">
    <ItemTemplate>
         <asp:Button runat="server" 
Text="<%!Convert.ToBoolean(Eval("Toggle")) %>" CommandName="ToggleClick"
CommandArgument='<%#Eval("Toggle") %>/>
   </ItemTemplate>
</asp:TemplateField>

and use OnRowCommand to handle this event. Smile | :)

Yes.. Actually I have written this directly.. Not tried out.... Can you let me know what error you are getting ... ?

Well, Eval("field") should be changed with your valid database field ??
Also change the fieldnames according to the datasource you bound to.

I have written this. theres is some problem. It shows "Convert.ToBoolean(true)".
What is the problem?

<asp:TemplateField HeaderText="Mode">
<ItemTemplate>
<asp:Button runat="server" Text="<%!Convert.ToBoolean(true) %>" CommandName="ToggleClick" CommandArgument=<%#true %>/>
</ItemTemplate>
</asp:TemplateField>

Thank You

Double Click Server Event for listBox Control

29-Oct-09 2:46

No no.. write this...

<asp:TemplateField HeaderText="Mode">
<ItemTemplate>
<asp:Button runat="server" Text="True" CommandName="ToggleClick" CommandArgument="True" />
</ItemTemplate>
</asp:TemplateField>

In CommandArgument you need to specify what you want to pass to the event generated when button is clicked. I have placed true there, which is not required. Replace appropriate element there (I mean the field which might be dependent on the button)

currently i m using asp.net 2.0 with sqlserver 2000.

here two tables playing the role. Table "A" and "B". 5 records to be inserted into the "A". after 1st record inserted in "A", the autoid has to be used for the "B" table's column value.

Is it possible using TRANSACTION? (i m not using any store procedure or triggers......only simple insertion).. help me

I do not really understand what you what. Do you mean something like this pseudo-code?

begin 
      start transansaction
      insert into a (somevalues)
      insert into b (select @@id from [last insert into a])
      insert into a (somevalues)
      insert into b (select @@id from [last insert into a])
      insert into a (somevalues)
      insert into b (select @@id from [last insert into a])
      insert into a (somevalues)
      insert into b (select @@id from [last insert into a])
      insert into a (somevalues)
      insert into b (select @@id from [last insert into a])
      if(anyerror)
            rollback()
      else
            commit()
end

Greetings
