索引(从零开始)必须大于或等于零，且小于参数列表的大小
GridView中有多列,Customer和Name是两个参数window.open('Uploads.aspx?Customer={0}&Name={1}')
异常详细信息: System.FormatException: 索引(从零开始)必须大于或等于零，且小于参数列表的大小。
如果只用1个参数Customer={0}没有问题的. --------------------编程问答-------------------- 你的参数肯定有问题
把代码全帖出来 --------------------编程问答-------------------- row.Attributes["ondblclick"] = String.Format("javascript:dbl_click=true;window.open('Uploads.aspx?Customer={0} & Name={1}');", GridView1.DataKeys[row.RowIndex].Value.ToString());
--------------------编程问答--------------------
这不只提供了GridView1.DataKeys[row.RowIndex].Value.ToString()一个参数吗？那Name的参数的值呢？ --------------------编程问答-------------------- {0}需要一个参数，{1}需要另一个参数。
而你只给了一个参数。 --------------------编程问答--------------------
你只提供一个参数啊！！
还有个参数呢！！ --------------------编程问答--------------------
if (row.RowType == DataControlRowType.DataRow)
{
row.Attributes["ondblclick"] = String.Format("javascript:dbl_click=true;window.open('Uploads.aspx?Customer={0} & Name={1}');", GridView1.DataKeys[row.RowIndex].Value.ToString(),GridView1.DataKeys[row.RowIndex].Value.ToString());
}
有2个参数就没有问题了,但是GridView1.DataKeys[row.RowIndex].Value.ToString()什么意思?能否把这两个指向到GridView的第3列和GridView的第5列 --------------------编程问答-------------------- GridView1.Rows[e.Row.Index].Cells[列].Value.ToString(); --------------------编程问答-------------------- 还是不行,GridView1.DataKeys[row.RowIndex].Value.ToString()语句是要放在protected override void Render(HtmlTextWriter writer)下面的
--------------------编程问答--------------------
protected override void Render(HtmlTextWriter writer)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Attributes["ondblclick"] = String.Format("javascript:dbl_click=true;window.open('Uploads.aspx?Customer={0} & Name={1}');", GridView1.DataKeys[row.RowIndex].Value.ToString(), GridView1.DataKeys[row.RowIndex].Value.ToString());
}
}
base.Render(writer);
}
GridView1.DataKeys[row.RowIndex].Value.ToString(), GridView1.DataKeys[row.RowIndex].Value.ToString());怎样才能指向到GridView的第3列和GridView的第5列 --------------------编程问答-------------------- 高手帮忙啊 --------------------编程问答-------------------- row.Cells[2].Value.ToString()//第三列
row.Cells[4].Value.ToString()//第五列 --------------------编程问答-------------------- 又遇到个问题,比如row.Cells[2].Value.ToString()列的值为空的时候,怎样让它取row.Cells[3].Value.ToString()列的值,如果第2和3列都为空就取固定值"none",请指教.
--------------------编程问答-------------------- 代码重新发
protected override void Render(HtmlTextWriter writer)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Attributes["ondblclick"] = String.Format("javascript:dbl_click=true;window.open('Uploads.aspx?Customer={0} & Name={1}');", row.Cells[2].Value.ToString(),row.Cells[4].Value.ToString());
}
}
base.Render(writer);
}
protected override void Render(HtmlTextWriter writer)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Attributes["ondblclick"] = String.Format("javascript:dbl_click=true;window.open('Uploads.aspx?Customer={0} & Name={1}');", row.Cells[2].Value.ToString(),row.Cells[4].Value.ToString());
}
}
base.Render(writer);
}
补充：.NET技术 , ASP.NET
