Hi

Anyone knows how to access to a value of a row in a datalist. Something like this in datagrid
Dim str = MyDataGrid.Cell(0).tex

I would like something like this
Dim str = DataBinder.Eval(MyDatalist.Items(count).DataItem, "customerId")
but it doesn't work.
 
Hi Jenn,
You can access the Datalist values of a row like this :
In the ItemDataBound event of the DataList,
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem){



object row_items=e.Item.DataItem;

// If you have a column called customerId,

object items = e.Item.DataItem;

string str1=Convert.ToString(DataBinder.Eval(row_items,"customerId"));

}

Additional info:

You can find the controls in thge ItemTemplate of your datalist :

In ItemDataBound event :

eg :
((LinkButton)e.Item.FindControl("LinkB")).CommandArgument=e.Item.ItemIndex.T
oString();

This will set the commandargument for the Linkbutton,
LinkB.





The above code is in C#.

You can easily convert it into VB.NET.Let me know if you have any
problems.



Hope this helps.

Hi Marshal

Thanks for the reply, but I'm looking at accessing the datalist values from outside of the ItemDatabound event. So what I did was to loop through the datalist like this

dim i as int=
while i<Mydatalist.items.coun

dim str = MyDatalist.Items(i).DataItem("customerid") <-- this does not wor

end whil

In datagrid you can easily do that like this

Dim str = MyDataGrid.Items(i).Cell(0).tex

Is there a way to do this with datalist

Hi Jenn,
In DataList ItemTemplate used for how each item will be rendered.
For example,
<ItemTemplate>
Customer <%#
Convert.ToString(DataBinder.Eval(ContainerDataItem,"customerid"))%>
<ItemTemplate>

You can access datalist values out side of Itemdatabound..
You can use DataKeys collection to retrieve
information from the datalist.
For example if you have a delete event handler,
Dim str1 As
String=DataList1.DataKeys(e.Item.ItemIndex)

Here is a link on MSDN on DataList web server control.
