一道关于GridView中RowDeleting的问题
代码如下：
protected void GridView2_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string sqlstrUD = "update xsxx set ";
sqlstrUD += "xm= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[2].Controls[0]).Text + " ', ";
sqlstrUD += "xb= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[3].Controls[0]).Text + " ', ";
sqlstrUD += "pwd= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[4].Controls[0]).Text + " ', ";
sqlstrUD += "bjmc= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[5].Controls[0]).Text + " ', ";
sqlstrUD += "zymc= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[6].Controls[0]).Text + " ', ";
sqlstrUD += "xxzydh= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[7].Controls[0]).Text + " ' ";
sqlstrUD += " where xh= ' " + ((TextBox)GridView2.Rows[e.RowIndex].Cells[1].Controls[0]).Text + " ' ";
bool test= da.ExceSQL(sqlstrUD); //调用方法执行SQL语句
if(test==true)
{
Response.Write( "更新成功 ");
}
else
{
Response.Write( "更新失败 ");
}
GridView2.EditIndex = -1;
dlBind();
}
以上对数据库的更新完全可以，而下面的删除代码出了问题
protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string sqlstrDT= "delete from xsxx where xh= ";
sqlstrDT += " ' " +((TextBox)GridView2.Rows[e.RowIndex].Cells[1].Controls[0]).Text+ " ' ";
bool test = da.ExceSQL(sqlstrDT);
if (test == true)
{
Response.Write( "删除操作成功！ ");
GridView2.EditIndex = -1;
dlBind();
}
else
{
Response.Write( "删除失败！ ");
}
}
错误显示行“sqlstrDT += " ' " +((TextBox)GridView2.Rows[e.RowIndex].Cells[1].Controls[0]).Text+ " ' ";”
错误信息：指定的参数已超出有效值的范围。参数名: index
其中 数据库中xh的类型为char 要删除的值中 xh= '012006026531 '
希望网友抽空帮忙解决一下， 使其能正常删除，谢谢啦！！
[解决办法]
跟踪一下。Cells[1]中是否有控件。

所以报错

单元格位置不对
等你学会了用模版列去FindControl就再也不会用Cells[X].Controls[Y]这种容易出错的语法了
