如何在数据集中的确切位置动态添加行

Question

I write a code to add dynamical column and row to a data set but the field is added some where in my data-set so can any one tell how can I resolve this

My code

for (int i = 0; i < AchDB.Amount1.Count; i++)
    {
        DataColumn dc = new DataColumn("Amount1");
        local_ds.Tables[0].Columns.Add(dc);
        local_ds.Tables[0].Rows.Add(AchDB.Amount1[i]);
    }

I need as per in the image shown

Answer 1

Maybe you can use this:

DataColumn dc = new DataColumn("Amount1");
local_ds.Tables[0].Columns.Add(dc);

for (int i = 0; i < AchDB.Amount1.Count; i++)
{
    local_ds.Tables[0].Rows[i]["Amount1"] = AchDB.Amount1[i];
}

I did put the code for adding a new column outside the loop. I think adding the column once will be applicable for all rows.

You can use the "InsertAt" method of DataTable for inserting the row at specific position. For the columns there is no direct way of adding a column at a specific position. When you add a column to a datatable - it always gets added at the last.

dt.Rows.InsertAt(newRowObject,pos);
