GridView在做行编辑的时候和删除的时候出现索引超出范围。必须为非负值并小于集合大小。

[ld_17941733]

如题
怎么办 着急啊 各位帮帮忙 我上代码
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
//--------------------------这个是在GridView上进行编辑事件处理
GridView1.EditIndex = e.NewEditIndex;
//bind();
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
//--------------------------这个是在GridView上进行删除
GridView1.DataKeyNames = new string[] { "id" };
string aa = GridView1.DataKeys[e.RowIndex].Value.ToString();
string sql = "delete from stx_project_foreign where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
OracleCommand cmd = new OracleCommand(sql, DbConn.GetConn());
cmd.Connection.Open();
cmd.ExecuteNonQuery();
cmd.Connection.Close();
//bind();
}

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//--------------------------这个是在GridView上进行修改
string sql = "update stx_project_foreign set 题目='"+((TextBox)(GridView1.Rows[e.RowIndex].Cells[5].Controls[0])).Text.ToString().Trim() + "' where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
OracleCommand cmd = new OracleCommand(sql, DbConn.GetConn());
cmd.Connection.Open();
cmd.ExecuteNonQuery();
cmd.Connection.Close();


GridView1.EditIndex = -1;


}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
//--------------------------这个是在GridView上进行取消操作
GridView1.EditIndex = -1;
// bind();
}

在线等 谢谢

[ld_17941733]

string aa = GridView1.DataKeys[e.RowIndex].Value.ToString();
请看这里 我测试在这里出现了 错误

[lorinzhang]

string aa = GridView1.DataKeys["id"].Value.ToString();

[fuda_1985]

string aa =(强制转换成控件原类型) (GridView1.Items[e.RowIndex].findcontrl("存id的控件")).Text(或都value反正就是存值的那个属性。);

[zbssoft]

全在这儿了

protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        this.GridView1.EditIndex = -1;
        bind();
    }
    protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        int id;
        id = Convert.ToInt32(this.GridView1.DataKeys[e.RowIndex].Value);
        DataSet ds1 = new DataSet();
        string st1 = "delete from news where newid=" + id + "";
        bool inser = db.UpdataBySql(st1);
        if (inser == true)
        {
            //((LinkButton)e.RowIndex.Cells[10].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.RowIndex.Cells[2].Text + "\"吗?')");

        }
        bind();
    }
    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        this.GridView1.EditIndex = e.NewEditIndex;
        bind();
    }
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        TextBox title;
        
        TextBox kind;
        TextBox href;
        TextBox date;
        TextBox time;
        int id=Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
        title = (TextBox)this.GridView1.Rows[e.RowIndex].Cells[2].Controls[0];
        kind = (TextBox)GridView1.Rows[e.RowIndex].Cells[4].Controls[0];
        href=(TextBox)GridView1.Rows[e.RowIndex].Cells[5].Controls[0];
        date = (TextBox)GridView1.Rows[e.RowIndex].Cells[6].Controls[0];
        time = (TextBox)GridView1.Rows[e.RowIndex].Cells[7].Controls[0];
        string ti = title.Text.Trim();
        string ki = kind.Text.Trim();
        string hr = href.Text.Trim();
        string da = date.Text.Trim();
        string tim=time.Text.Trim();
        DataSet ds2 = new DataSet();
        string str2 = "update news set title='"+ti+"',kind='"+ki+"',href='"+hr+"',dates='"+da+"',times='"+tim+"' where newid="+id+"";
        bool inser = db.UpdataBySql(str2);
        if (inser == true)
        {

        }
        else { }
        GridView1.EditIndex = -1;
        bind();
    }

不知道怎么样，多谢楼主

[x276912756]

帮顶！！！！！！！！！！！！！！！！！！！！！！

[ld_17941733]

还是不行 别拿 清清月儿 的七十二绝技混弄我 她写的是好 我就是照着她写的 但是我们绑定的方法不一样
我现在就问 为什么出现
"GridView在做行编辑的时候和删除的时候出现索引超出范围。必须为非负值并小于集合大小"
这样的错误 多谢各位了

[zhoulingsmile]

帮你顶。。。

[jerry_k]

把GridView1.DataKeyNames = new string[] { "id" };
放在 Page_Load()函数中定义，试一下。

[ld_17941733]

this.GridView1.DataKeyNames = new string[] { "ID" };//主键
GridView1.DataBind();
string aa = this.GridView1.DataKeys[e.RowIndex].Value.ToString();
string sql = "delete from stx_project_foreign where id='" + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
OracleCommand cmd = new OracleCommand(sql, DbConn.GetConn());
cmd.Connection.Open();
cmd.ExecuteNonQuery();
cmd.Connection.Close();
GridView1.DataBind();

[ld_17941733]

这个好用

[hztltgg]

GridView1.DataKeyNames = new string[] { "id" };

这个要在绑定之前执行的吧，你在要删除了才来定义key，太晚了

[z195389542]

你看一下 e.rowindex.是多少就不行了
错误提示已经说明白了。gridview中没有那一行。

[liufenfen]

在绑定的时候，加上这一句GridView1.DataKeyNames = new string[] { "id" };
在GridView1.DataBind();之前

[lisonghe]

jerry_k
的方法能行

[happy664618843]

GridView1.DataKeyNames = new string[] { "ID" };//主键

GridView1.Rows[row.RowIndex].FindControl() as TextBox;

[yangbo4235]

"GridView1.DataKeyNames = new string[] { "id" };

这个要在绑定之前执行的吧，你在要删除了才来定义key，太晚了"

这个就是我想说的，你应该在页面中<asp:GridView DataKey="id"> ,这样就ok了
