如何在GridView点击事件中自动生成Button中获取标题名称。标题列不能相同......所有时间......
因此，根据列标题，我们必须进一步处理。请帮助找到列标题。
我们通过以下代码找到rowindex
var rowIndex = ((GridViewRow)((Control)sender).NamingContainer).RowIndex;
GridView内单击链接按钮时找到GridView的列索引？

答案 0 :(得分：0)
您可以使用此代码段。它循环所单击按钮所在行中的所有单元格并尝试查找正确的列。
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
//get the control that fired the method
Control control = e.CommandSource as Control;
//get the row containing the control
GridViewRow gvr = control.NamingContainer as GridViewRow;
//get the row number
int rowNumber = gvr.RowIndex;
//declare the column variable
int columnNumber = -1;
//loop all the columns in the gridview
for (int i = 0; i < GridView1.Columns.Count; i++)
{
//try to find the button that was clicked in each individual cell
Button button = GridView1.Rows[rowNumber].Cells[i].FindControl(control.ID) as Button;
//if the button is found set the column number
if (button != null)
{
columnNumber = i;
}
}
//get the column name
Label1.Text = GridView1.HeaderRow.Cells[columnNumber].Text;
}
