从查询表适配器将数据绑定到网格View控件 [英] bind data to a grid View control from a Queries Table Adapter
问题描述
我正在使用数据集向导来生成我的数据集.现在，我添加了一个带有4个查询的查询表适配器，现在正尝试将数据输入到数据网格View控件中，以显示按查询排序的数据.但是，当我将数据绑定到数据网格View控件时，我总是收到错误消息.这是我的代码 导入
Hi I am using a dataset wizard to generate my dataset. I have now add a Queries Table Adapter with 4 queries inside it and am now trying to feed the data in to a data grid View control to display the data sorted by query. But I keep getting errors when I bind the data to the data grid View control. Here is my code Imports

推荐答案
Mathew，
在您的代码中，将数据表设置为数据集，然后填充数据集.我不确定这是否是2008年的新功能，但请尝试两件事，忽略数据集并使用单个数据表进行填充.我什至不确定没有解析表的数据集是否可以附加到数据表.
我描述的方式有很多参考，我很好奇您的来源这个数据集向导是?
无论如何，今天早上我和一个有类似问题的人一起工作.看看我写的内容是否可以帮助您解决这个问题.

Hi Mathew,
In your code you set a data table to a dataset, and you fill the dataset. I'm not sure if this is something new in 2008, but try two things, ignore the dataset and work with individual data tables for the fill. I'm not even sure if a dataset, that doesn't have the table parsed can attach to a datatable.
There are many references for the way I'm describing, I'm curious what your source of this dataset wizard is?
In any event, I worked with someone this morning, that had a similar problem. See if anything I wrote could help you with this.

look at the code that sets up the datatable for the add, if you utilize that it may help, but you will need to flesh it out a little, to adapt it to your application.
Best of Luck,
John.
