[英]Get Row Values from onrowupdating GridView Event
Hi I'm trying to do some Updates on a grid row programatically ... I have this so far ... 嗨,我正在尝试以编程方式对网格行进行一些更新...到目前为止,我已经做到了...
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><%--to test cmd str--%>
<asp:GridView ID="_gv_Cus" runat="server" AutoGenerateColumns="False"
AutoGenerateEditButton="True" style="font-size: medium" onrowupdating="gvDetails_RowUpdating"
onrowediting="gvDetails_RowEditing" onrowcancelingedit="gvDetails_RowCancelingEdit" >
<HeaderStyle BackColor="#57768f" ForeColor="White" />
<RowStyle BackColor="#dae2e8" ForeColor="Black" HorizontalAlign="left" />
<AlternatingRowStyle BackColor="#ffffff" ForeColor="Black" />
<Columns>
<asp:BoundField DataField="code" HeaderText="code" ReadOnly="True" SortExpression="code" Visible="false" />
<asp:BoundField DataField="Desc" HeaderText="Decription" SortExpression="Desc" >
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
</Columns>
</asp:GridView>
Code Behind: 背后的代码:
// Having Problems Here
protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
var tbl = dd_CusCodes.SelectedValue;
using (var con = new SqlConnection())
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["RM_V1.0CS"].ConnectionString;
int index = Convert.ToInt32(e.RowIndex);
GridViewRow row = _gv_Cus.Rows[index];
string code = row.Cells[0].Text;
string desc = row.Cells[1].Text;
con.Open();
var cmd = new SqlCommand("update " + tbl + " set [Desc]='" + desc + "' where code=" + code, con) {CommandType = CommandType.Text};
//TextBox1.Text = cmd.CommandText;
cmd.ExecuteNonQuery();
con.Close();
_gv_Cus.EditIndex = -1;
BindGrid();
}
}
protected void gvDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
_gv_Cus.EditIndex = e.NewEditIndex;
BindGrid();
}
protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
_gv_Cus.EditIndex = -1;
BindGrid();
}
protected void BindGrid()
{
var tbl = dd_CusCodes.SelectedValue;
if (tbl != string.Empty)
{
using (var con = new SqlConnection())
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["RM_V1.0CS"].ConnectionString;
con.Open();
try
{
var cmd = new SqlCommand("SELECT [code] " +
",[desc] " +
"FROM [dbo].[" + tbl + "] order by [desc]", con) { CommandType = CommandType.Text };
_tx_Recruit.Text = cmd.CommandText.ToString();
var read = cmd.ExecuteReader();
_gv_Cus.DataSource = read;
_gv_Cus.DataBind();
read.Close();
}
catch (Exception ex)
{
ErrHandler.WriteError(ex.ToString());
}
finally
{
con.Close();
}
}
}
}
How can I get the row values in the onrowupdating GridView Event ?? 如何在onrowupdating GridView事件中获取行值?
Try the NewValues collection of the gridviewupdateeventargs. 尝试使用gridviewupdateeventargs的NewValues集合。

e.NewValues("Desc")
