问题描述

当我从该行中触发一个dropbox selectedindexchange时，我试图从gridview中的一行获取一个特定的数据列...



我填充了grid和每个rown都有一个包含数据的下拉框，当我尝试更改该下拉值时，我想从该行获取'id'或'firstname'等。



我目前正在尝试这样的事情

I populate the grid and each rown has a dropdown box with data, when i try to change that dropdown value i want to get the 'id' or 'firstname' ect from that row.

Im currently trying something like this

protected void ddlCategory_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList ddlCategory = (DropDownList)sender;

        GridViewRow row = (GridViewRow)ddlCategory.NamingContainer;

        int id = Convert.ToInt32(row.Cells[0]);
string name = Convert.ToString(row.Cells[1]);
}

推荐答案

如果你正在使用BindingSource，你可以处理CurrentChanged事件，如果没有，请点击此链接。



在DataGridViewComboBoxColumn期间触发的事件SelectedIndexChanged



基本上你必须处理EditingControlShowing的事件，然后为SelectedIndexChanged设置一个事件处理程序。

If you're using a BindingSource you can handle CurrentChanged event, if not, follow this link.

Event that fires during DataGridViewComboBoxColumn SelectedIndexChanged

Basically you must handle EditingControlShowing's event and then, set a event handler for SelectedIndexChanged.
