How to add rows to datagridview winforms?
提问by Viva
I want to add rows to a datagridview. I tried a lot of possibilities, but it doesn't appear anything on it. I think the best solution is to create a datatable, and then to use it as datasource for my gridview. I use winforms. Please, any other idea is welcomed . This is what I have tried so far:
我想将行添加到datagridview. 我尝试了很多可能性，但它没有出现任何内容。我认为最好的解决方案是创建一个数据表，然后将其用作我的 gridview 的数据源。我使用winforms。拜托，欢迎任何其他想法。这是我迄今为止尝试过的：
public DataTable GetResultsTable()
{
DataTable table = new DataTable();
table.Columns.Add("Name".ToString());
table.Columns.Add("Color".ToString());
DataRow dr;
dr = table.NewRow();
dr["Name"] = "Mike";
dr["Color "] = "blue";
table.AcceptChanges();
return table;
}
public void gridview()
{
datagridview1.DataSource=null;
datagridview1.DataSource=table;
}

i found two mistake in your code:
我在你的代码中发现了两个错误：
dr["Color "] = "blue";Column Color should without spacedr["Color"] = "blue";You forgot to add row to the table
table.Rows.Add(dr);
dr["Color "] = "blue";列颜色应该没有空格dr["Color"] = "blue";您忘记向表中添加行
table.Rows.Add(dr);
you can try this
你可以试试这个
public DataTable GetResultsTable()
{
DataTable table = new DataTable();
table.Columns.Add("Name".ToString());
table.Columns.Add("Color".ToString());
DataRow dr = table.NewRow();
dr["Name"] = "Mike";
dr["Color"] = "blue";
table.Rows.Add(dr);
return table;
}
public void gridview()
{
datagridview1.DataSource = GetResultsTable();
}

There are different ways , but in different conditions.
有不同的方式，但在不同的条件下。
As my following code shows you gridview.add method in case of string array:
正如我的以下代码在字符串数组的情况下向您展示了 gridview.add 方法：
datagridview1.Rows.Add( { val, val, val });
It depends upon context and situation at which you want to apply it.
这取决于您要应用它的上下文和情况。

DataGridView dgv = new DataGridView();
DataTable table = new DataTable();
dgv.DataSource = table;
table.Columns.Add("Name");
table.Columns.Add("Color");
table.Rows.Add("Mike", "blue");
table.Rows.Add("Pat", "yellow");
this.Controls.Add(dgv);

Try This method:
试试这个方法：
dataGridView1.Columns.Add("Col1", "Name"); // "Col1" is the name of the column and "Name" is the column header text"
dataGridView1.Columns.Add("Col2", "Age");
dataGridView1.Rows.Add("ABC", "25");
Hope this helps :)
希望这可以帮助 ：）
