期间使用以下代码更新gridview中的值

OnUpdating

此代码在网格视图的第一页中正常工作，但是当我尝试编辑第二页时它不起作用。当我单击编辑按钮时，正在加载相应的行编辑模板。当我单击保存而不是保存到第二页时，第一页行被修改。例如，如果我在第二页的第二行中单击编辑，并且在我单击更新后，第一页的第三行被修改为新值而不是第二页的第二行。

我的RowEditing和CancelEditing代码如下，

protected void grid_view_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    GridViewRow row = (GridViewRow)grid_view.Rows[e.RowIndex];
    int number = Convert.ToInt32(((TextBox)row.Cells[3].FindControl("flatnumber")).Text);
    string type = ((DropDownList)row.Cells[4].FindControl("flattype")).Text;
    int max = Convert.ToInt32(((DropDownList)row.Cells[5].FindControl("flatvacancy")).Text);
    string flatID = ((Label)row.Cells[0].FindControl("flatid")).Text;
    DataTable dt = (DataTable)ViewState["Table"];
    DataRow[] datarow = dt.Select("ID='" + flatID + "'");
    dt.Rows[e.RowIndex].BeginEdit();
    dt.Rows[e.RowIndex]["Number"] = number;
    dt.Rows[e.RowIndex]["Type"] = type;
    dt.Rows[e.RowIndex]["Vacancy"] = max;
    dt.Rows[e.RowIndex].EndEdit();
    dt.AcceptChanges();
    ViewState["Table"] = dt;
    grid_view.EditIndex = -1;
    grid_view.DataSource = dt;
    grid_view.DataBind();
}

您可以仅使用e.RowIndex访问更新的值，但要在Datatable中进行更改，您必须将grid_view.PageIndex和grid_view.PageSize的产品添加到e.RowIndex以进行更改在实际的行中。

protected void grid_view_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    GridViewRow row = (GridViewRow)grid_view.Rows[e.RowIndex];
    int number = Convert.ToInt32(((TextBox)row.Cells[3].FindControl("flatnumber")).Text);
    string type = ((DropDownList)row.Cells[4].FindControl("flattype")).Text;
    int max = Convert.ToInt32(((DropDownList)row.Cells[5].FindControl("flatvacancy")).Text);
    string flatID = ((Label)row.Cells[0].FindControl("flatid")).Text;
    DataTable dt = (DataTable)ViewState["Table"];
    int row1=e.RowIndex+(grid_view.PageIndex*grid_view.PageSize)
    dt.Rows[row1].BeginEdit();
    dt.Rows[row1]["Number"] = number;
    dt.Rows[row1]["Type"] = type;
    dt.Rows[row1]["Vacancy"] = max;
    dt.Rows[row1].EndEdit();
    dt.AcceptChanges();
    ViewState["Table"] = dt;
    grid_view.EditIndex = -1;
    grid_view.DataSource = dt;
    grid_view.DataBind();
}

GridView RowUpdating在第二页中不起作用
