Question

我正在使用asp gridview元素对数据库进行搜索并使用

返回一些数据

    <asp:GridView ID="storedRecordsGrid" AutoGenerateSelectButton="true"  emptydatatext="No data    available." runat="server">

所以我有一个可以使用popolated的gridview，每行都有自己的select事件。当用户选择一行时，我想使用该行中的数据来填充页面上的texbox。

    protected void OnRowCommand(GridViewCommandEventArgs e)
        { 

        }

所以我有这个方法，我有我的文本框，但当选择甚至触发时，我不确定如何为所选行的每个列存储数据。我想拥有的是类似的东西。

    protected void OnRowCommand(GridViewCommandEventArgs e)
        { 
         mytextbox.text=datagridcolumn.value   
        }

我正在使用.net 2.0 而我现在的c＃代码看起来像这样。

private DataTable fillGrid(string dComplainantFName,string dComplainantlName)
   {
        string server = "";
        using (SqlConnection cnx = new SqlConnection(server))
        using (SqlCommand cmd = new SqlCommand("ComplaintReportLookUp", cnx) { CommandType = CommandType.StoredProcedure })
        using (DataTable dt = new DataTable())
        {
            cmd.Parameters.AddWithValue("@fName", dComplainantFName);
            cmd.Parameters.AddWithValue("@lName", dComplainantlName);
            try
            {
                cnx.Open();
                dt.Load(cmd.ExecuteReader());
                cnx.Close();
                return dt;
            }
            catch (Exception ex)
            {
                throw new Exception("Error executing MyProcedureName.", ex);
            }
        }

    }
   protected void executeGrid(object sender, EventArgs e)
        {
            storedRecordsGrid.DataSource = this.fillGrid(dComplainantFName.Text,dComplainantLName.Text);
            storedRecordsGrid.DataBind();
        }
    protected void OnRowCommand(GridViewCommandEventArgs e)
        { 

        }

感谢您的帮助

感谢蒂姆的帮助，这就是我最终的工作。

    protected void gridSelectedIndexChanged(Object sender, EventArgs e)
    {
    var row = ((GridView)sender).SelectedRow;
    //var cell1Text = row.Cells[0].Text; // should be your autogenerated select cell 
    dComplainantFName.Text = row.Cells[1].Text.Replace("&nbsp;", ""); // Text in column 1 (the first column of your DataTable) 
    dComplainantLName.Text = row.Cells[2].Text.Replace("&nbsp;", ""); // Text in column 2 (the second column of your DataTable) 
    dComplainantMName.Text = row.Cells[3].Text.Replace("&nbsp;", "");
    dComplainantAddress.Text = row.Cells[4].Text.Replace("&nbsp;", "");
    dComplainantCity.Text = row.Cells[5].Text.Replace("&nbsp;", "");
    dComplainantState.Text = row.Cells[6].Text.Replace("&nbsp;", "");
    dComplainantZip.Text = row.Cells[7].Text.Replace("&nbsp;", "");
    dComplainantPhone.Text = row.Cells[8].Text.Replace("&nbsp;", "");
    storedRecordsGrid.Visible = false;
    }

使用GridView的SelectedIndexChanged事件，在其他事件中，例如RowCommand或SelectedIndexChanging，SelectedRow属性为null。这也是符合您要求的适当事件：

protected void Grid_SelectedIndexChanged(Object sender, EventArgs e)
{
    var row = ((GridView)sender).SelectedRow;
    var cell1Text = row.Cells[0].Text; // is your autogenerated select cell(String.Empty)
    var cell2Text = row.Cells[1].Text; // Text in column 2 (the first column of your DataTable)
    var cell3Text = row.Cells[2].Text; // Text in column 3 (the second column of your DataTable)
    TextBox1.Text = cell2Text; // etc.
}

注意：如果您未将AutoGenerateSelectButton设置为true并使用TemplateFields，则应在FindControl上使用SelectedRow获取对控件的引用。

如果您仍然坚持使用RowCommand，则可以从CommandArgument获取所选行：

protected void Grid_RowCommand(Object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Select")
    {
        var rowIndex    = int.Parse(e.CommandArgument.ToString())
        var selectedRow = ((GridView)sender).Rows[rowIndex];
        var cell1Text   = selectedRow.Cells[0].Text; // is your autogenerated select cell(String.Empty)
        var cell2Text   = selectedRow.Cells[1].Text; // Text in column 2 (the first column of your DataTable)
    }
}
