Question

I am trying to code a sort routine against a dynamicaly populated gridview names Users. I have a syntax error in the C# code where I am trying to populate a column in a row of a the datatable.

    for (int j = 0; j <= Users.Rows.Count - 1; j++) 
    { 
        DataRow dr = default(DataRow); 
        GridViewRow row = Users.Rows[j]; 
        dr = dt.NewRow(); 
        DataView dvUsers = new DataView(dt); 

        for (int i = 0; i <= row.Cells.Count - 1; i++) 
        { 
            dr.Item(i) = row.Cells[i].Text; 
        } 

        dt.Rows.Add(dr); 
    } 

Error message:

System.Data.DataRow does not contain a definition for “Item”

Can someone help with the correct syntax to assign this value to the datarow?

I am new to C#

thank you,

You just need to change the line

dr.Item(i) = row.Cells[i].Text; 

to

dr[i] = row.Cells[i].Text; 

Assuming the columns in the data table match the ordering of the cells in the table.

() are used to call methods, while [] indicates an indexer. This is the reason for the compile error. There isn’t a method Item on DataRow, it is an indexer.

EDIT

Changed dr.Item[i] to dr[i]. As explained in the comments, Item is the default indexer, so you don’t specify the property, the index provided to the object itself will be applied to the Item indexer.
