将列添加到datagridview [英] add column to datagridview

问题描述

我正在处理一个现有表单，该表单将填充datagridview，如下所示:
它使用的是bindingsource，因为我在设计器的窗体底部看到BindingSource控件.

Hi,
I am working on an existing form which populates a datagridview as follows:
It is using a bindingsource because I see at the bottom of the form in designer the BindingSource control.

private void PopulateGrid()
        {
            System.Data.DataTable dt = TFNGet();
            fBS.DataSource = dt;
            dGV.AutoGenerateColumns = false;
            dGV.DataSource = fBS;
            int i = 0;
            dGV.Columns[i++].DataPropertyName = "BCode";
            dGV.Columns[i++].DataPropertyName = "FDCode";
            dGV.Columns[i++].DataPropertyName = "Currency";
            dGV.Columns[i++].DataPropertyName = "CCcy";
            dGV.Columns[i++].DataPropertyName = "VD";
            dGV.Columns[i++].DataPropertyName = "BS";
            dGV.Columns[i++].DataPropertyName = "A";
            dGV.Columns[i++].DataPropertyName = "PCN";
            dGV.Refresh();
        }

现在，我想添加一个复选框列作为此dGV的第一列，称为失败"
因此，我正在执行以下操作，但错误是:
索引超出范围.必须为非负数，并且小于集合的大小.

Now I would like to add a checkbox column as the first column to this dGV called "Failed"
So I am doing the following to do this but the error is:
"Index was out of range. Must be non-negative and less than the size of the collection.

private void PopulateGrid()
        {
            System.Data.DataTable dt = TFNGet();

		dt.Columns.Add("Failed", typeof(Boolean));

            fBS.DataSource = dt;
            dGV.AutoGenerateColumns = false;
            dGV.DataSource = fBS;
            int i = 0;
            dGV.Columns[i++].DataPropertyName = "BCode";
            dGV.Columns[i++].DataPropertyName = "FDCode";
            dGV.Columns[i++].DataPropertyName = "Currency";
            dGV.Columns[i++].DataPropertyName = "CCcy";
            dGV.Columns[i++].DataPropertyName = "VD";
            dGV.Columns[i++].DataPropertyName = "BS";
            dGV.Columns[i++].DataPropertyName = "A";
            dGV.Columns[i++].DataPropertyName = "PCN";

	//checkbox column
            dGV.Columns[i++].DataPropertyName = "Failed";

            dGV.Refresh();
        }

有什么想法吗?
谢谢

Any thoughts please?
Thanks

推荐答案

在哪里定义其他列?

您可能在不存在的列上设置了DataPropertyName.哪一个实际上导致了异常?
dGV.Columns[i++].DataPropertyNane = "Failed"之一还是dGV.Columns[i++].DataPropertyNane = "FDCode"

我建议第二个，因为我只看到添加了一个列，

Where are the other columns being defined?

It is likely you are setting the DataPropertyName on a column that does not exist. Which one is actually causing the exception?
The one of dGV.Columns[i++].DataPropertyNane = "Failed" or is it maybe dGV.Columns[i++].DataPropertyNane = "FDCode"

I suggest the second because I am only seeing one column added,

dt.Columns.Add("Failed", typeof(Boolean));

因此，看来您正在将此列设置为"BCode"，然后尝试设置不存在的列.

So it seems you are setting this column to be "BCode" and then trying to set columns that do not exist.
