Asked by: dba123

I get a null exception when trying to access a value for the current boundrow in my repeater.  I'm probably just  missing something here?

 

    public void rptSearchStrings_DataBound(Object sender, RepeaterItemEventArgs e)
    {
 

    public void rptPartStrings_DataBound(Object sender, RepeaterItemEventArgs e)
    {
        DataRowView dv = e.Item.DataItem as DataRowView;
        string partString = ((DataRowView)e.Item.DataItem).Row["partstring"].ToString();

....

 dv is null

....

 dv is null

try to cast it as a datarow
the sample from msdn is for a object data source but you are nearly there - you dv is null because i think its a row and not a view

I'm still not finding the right way to access the current row and a specific value in the row's columns.

 

by: sm394Posted on 2008-11-04 at 08:45:33ID: 22877956

try that
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{

DataRowView dv = e.Item.DataItem as DataRowView;
string partString = ((DataRowView)e.Item.DataItem).Row["partstring"].ToString();

}

sm394, I don't see how yours is different from what I just posted originally.

 

by: dba123Posted on 2008-11-04 at 09:02:19ID: 22878166

I put that check in for item or alternating item, and it makes no difference

 

by: dba123Posted on 2008-11-04 at 10:46:25ID: 22879181

figured it out.  You can just case the e.Data.Item to the orignal object type and use that type directly

(Product)e.Item.DataItem

then

Product.PropertyName (or column name really)
