GridEditableItem.ExtractValues issue

[Nick]

Hello,

I am using the ExtractValues method in my UpdateCommand method to retrieve a mapping of column names to values from an edited row. However, when I edit a row, the value mapped to its column stays the same in the hashtable, as well as in the grid. What could be the possible explanations for this?

protected void GrdConfig_UpdateCommand(object sender, GridCommandEventArgs e)
{
     Hashtable newValues = new Hashtable();
     ((GridEditableItem)e.Item).ExtractValues(newValues);
     Alert.Show(newValues["ColumnName"].ToString());
     ...
     Working SQL code
     ...
}

If anyone has had this problem as well, any help would be greatly appreciated because I am stuck at a wall right now.

I was able to (almost) fix my problem by changing the code where I retrieve the data from the DB to the PreRender method (it was originally in the PageLoad method). I am able to update one cell, and it displays on the grid and in the DB. However, I am trying to use an iterator to loop through the newValues and update each value in the database, how can I do this?

Hi Nick,

I suggest that you examine the online resources below which demonstrate how to force several grid items in edit mode and then update them on single button.

I hope they will help you to achieve the desired functionality.

Kind regards,
