You should either bind a datatable to a Gridview or when you bind a dataset, then you should tell the Gridview which datatable it should be bound to....
DataGridView1.AutoGenerateColumns = True;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = \"TableName\";

Am not able to bind the dataset to the gridview.

You should either bind a datatable to a Gridview or when you bind a dataset, then you should tell the Gridview which datatable it should be bound to....
DataGridView1.AutoGenerateColumns = True; DataGridView1.DataSource = ds; // dataset DataGridView1.DataMember = "TableName";
这篇关于将数据集绑定到gridview。的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
