如何在asp.net上的gridview事件rowEditing中获取值

Question

代码

 protected void grv_RowEditing(object sender, GridViewEditEventArgs e)
    {
         string name = (grv.Rows[e.NewEditIndex].Cells[1].Controls[0] as TextBox).Text;
    }

或字符串名称 grv.Rows [e.NewEditIndex] .Cells [1] .Value.ToString（）; //不起作用。

Answer 1

您需要再次对GridView进行数据绑定，才能访问 EditItemTemplate 中的控件。所以试试这个：

GridView1.EditIndex = e.NewEditIndex; 
GridView1.DataSource = somedatasource; //Bind Grid Than Find Control 
GridView1.DataBind();

Textbox txt= GridView1.Rows[e.NewEditIndex].FindControl("textboxid") as TextBox;
 string name = txt.TEXT

Answer 2

OnRow编辑，

protected void grv_RowEditing(object sender, GridViewEditEventArgs e)
{
grv.EditIndex = e.NewEditIndex;
grv.DataBind();

 //Find Controls Here like below:
 Textbox txt= grv.Rows[e.NewEditIndex].FindControl("YourTextBoxID") as TextBox;
 DropDownList ddl_branch = (DropDownList)grv.Rows[e.NewEditIndex].FindControl("ddl_branch");
Label lb_ = (Label)grv.Rows[e.NewEditIndex].FindControl("YourLabelID");
 }
