row_editing在网格视图中单击更新按钮时触发事件 [英] row_editing Event is fired on update button click in grid view

问题描述

我不知道我出了什么问题？我已经以编程方式创建了gridview，如下所示。

I don't know whats going wrong with me? I have created gridview programmatically as below.

 protected void Page_Load(object sender, EventArgs e)
        {
     GridView gv = new GridView();
            gv.ID = pId.ToString();
            gv.AutoGenerateEditButton = true;
            gv.DataKeyNames = ids;
            gv.RowEditing += gv_RowEditing;
            gv.RowUpdating += gv_RowUpdating;
            bindGv(pId, gv);
}

我写了以下方法。

I have written following methods.

void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
         GridView gv = sender as GridView;
        GridViewRow row = (GridViewRow)gv.Rows[e.RowIndex];
        ProductCategory pc = context.ProductCategories.First(s => s.Name ==gv.ID );
         TextBox txtName = row.FindControl("txtName") as TextBox;
         pc.Name = txtName.Text;
    }

    void gv_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridView gv = sender as GridView;
        gv.EditIndex = e.NewEditIndex;
        bindGv(Convert.ToInt32(gv.ID), gv);

}

但是当我在调试模式下运行它时...点击更新按钮调用gv_RowEditing方法而不是gv_RowUpdating ....



请帮助。

}
But when I run it in debugging mode...clicking on update button invokes gv_RowEditing method instead of gv_RowUpdating....

Please Help.

推荐答案

将逻辑绑定在IsPostback内部的gridview中检入page_load，如

Place the logic to bind the gridview inside IsPostback check in page_load like

protected void Page_Load(object sender, EventArgs e)
        {
            if(!IsPostback)
            {
               GridView gv = new GridView();
               gv.ID = pId.ToString();
               gv.AutoGenerateEditButton = true;
               gv.DataKeyNames = ids;
               gv.RowEditing += gv_RowEditing;
               gv.RowUpdating += gv_RowUpdating;
               bindGv(pId, gv);
            }
        }
