You simply copy the assembly Microsoft.Practices.EnterpriseLibrary.Data.dll to the temp folder of your web application:
C:/WINNT/Microsoft.NET/Framework/v1.1.4322/Temporary ASP.NET Files/autosys_procurements_web/14145ce2/887b2a67/

The data should be displayed in the HTML table with all features of datagrid(paging,edit and delete and go to page No).Simply with out using the datagrid.
Pls suggest me with some sample codings.

Hi Paul,
The html table control does not support data binding like a data-bound control such as datagrid, datalist ..., so if you want to use the html table, you need to walk through the record collection of the datasource, then build each row (tr) for the table. Also you also need to manage all the built-in features of the datagrid control like paging, sorting ....it seems overhead to you. So I'm curious that why you don't just use the datagrid control.

Thnak you for your suggession.
But I am trying to do the datagrid functionalty to the html table.
THanks you again

Hi..
I have a DataList that includes in its ItemTemplate an ImageButton which should use FieldNO(a DataItem field in the datasource ) as a QueryString to redirect() to another page:
Response.Redirect("default.aspx?FieldNO="+fieldNO+"&ProjectNO="+projectNO);
But i want this to happen only in a specific situation
(if(searchString!=null) is true) So the DataBinder.Eval() alone wont do what i want.So i used the following code in the method assigned to the OnCommand ImageButton attribute:
string fieldNO;
string argu=e.CommandArgument.ToString();
string[] argss=argu.Split(',');
if(searchString!=null)
{
DataRowView drv=(DataRowView)lProjects.Items[Convert.ToInt32(argss[1])].DataItem;
fieldNO=Convert.ToString(drv["FieldNO"]);
}
Where lProjects is the DataList And the Command Argument of the ImageButton is:
CommandArgument='<%#DataBinder.Eval(Container.DataItem,"ProjectNO")+","+Container.ItemIndex%>'
There is no relation between "ProjectNO" and the problem.The problem exists with the other field "FieldNO"
which i should get it from the datasource of the DataList in a specific condition.
But this code give me the error :
Object reference is not set to an instance.
Sorry if i couldnt explain my problem.
Could any one help?

+ You can use the ?: operator in the data binding expression to check if you should call the Eval method to populate the command argument.
+ You can wrap your sample code in a method, then simply call it in the data binding expression.
You can see the sample code from here[^].
|
|
|
|
|
These two ideas are exactly what i need.
May you give me code examples for them?...
|
|
|
|
|
You can find the examples from the provided link, and you can easily reuse it for your purpose:
+ Option 1:
<%# (strSearch is not null)? DataBinder.Eval(...):"" %>
+ Option 2:
<%# GetCommandArgument(Container.DataItem) %>
...
you can also define this method in the inline code.
Note: They all are the pseudo code.

Sorry,i didnt see the last statement in your previous message which was:
"You can see the sample code from here[^]."
Every thing is clear for me now.
Thank you very very much..I wont forget your help.

Hi..
after i build the code in my UserControl it gives me the error:
D:\MyWebApps\EProjects\UserControls\FieldProjectsList.ascx.cs(133): The type or namespace name 'DataBinder' could not be found (are you missing a using directive or an assembly reference?)
It seems to me that the UserControl is different from the WebForm in using the DataBinder class in the code behind page.
Could you help me in this problem?

|

Do you include the System.Web.UI namespace in the code-behind of the web user control?:
using System.Web.UI; In case you cannot figure out the problem, you might want to post your sample code in the user control.

Hi..Sorry for being too late.
After i added:
using System.Web.UI;
The build error disappeared but after i uploaded(updated) the project i got the error message:

You have helped me all the time thank you very much my teacher.

+ If you are using the ASP.NET 2.0, you should check out the ValidationGroup[^] feature.
+ If you are using the ASP.NEt 1.x, you may think of implementing your own validator.

im using asp.net 1.x and im not having my own validation control and im using asp.net required field validators.

I have a delivery page (binded to an Orders.mdf) that looks something like this. A simple webform that only handle ONE KIND of product but has various weights.
[lblDate] = shows the date selected, receive user selected date from the Calendar control.
[txtDeliveryOrderNo] = clerk types in a Delivery Order No.
[ddlPort] = dropdownlist showing a list of sea port where goods are imported, databound to a SQL ports.mdf
[ddlCustomer] = dropdownlist showing a list of customer, by name. Place where goods are delivered. Databound to a SQL customers.mdf
[ddlTruck] = dropdownlist showing which truck does the delivery
[txtGrossWeight] = user enter the gross weight of the item here and then click on an "ADD ITEM" button control to store record. Can have multiple items.
[btnSave] = saves the order record to the orders.mdf.
[btnCancel] = cancel the order record.
Is there anyone who can gimme a rough idea of how this could be done? Or has anyone done it before? I need it in C# codes.

I have a Product Order page. A user can order many products. To simplify it, user can just type the word "beer" into a textbox and click on ADD button, cookies and click on ADD button again, socks and click on ADD button again into a database. So, a database will show:
UserID
UserName
OrderID
Product List (Beer, Cookies, Socks)
After the user decides on the list of things to buy. Then the user click on SAVE, to save that record (with multiple items) to another database.
Very much like ADD TO CART concept. Anyone can guide me with this? How should I go about it?
There are a lot of people who ended up doing things wrongly, even if they had the best of intentions at the beginning. Then again, there is no guarantee the words they said were conveyed as they originally were intended to be. That's because those on the receiving end only hear what they want to hear.
