<asp:Label ID="lblGrossAmt" runat="server" Text='<%#Eval("GrossAmt") %>'/>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtftrGrossAmt" runat="server"/>
<asp:RequiredFieldValidator ID="rfvGrossAmt" runat="server" ControlToValidate="txtftrGrossAmt" Text="*" ValidationGroup="Validation" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="TDS">
<EditItemTemplate>
<asp:DropDownList ID="ddlTDS" runat="server">
<asp:ListItem Value="0"></asp:ListItem>

</asp:TemplateField>
protected void gvLLDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNew"))
{
TextBox txtATMID = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrATMID");
TextBox txtsubcode = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrSUBCODE");
TextBox txtLLName = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrLLName");
DropDownList ddlAggType = (DropDownList)gvLLDetails.FooterRow.FindControl("ddlftrAggType");
TextBox txtPrFrom = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrPrFrom");
TextBox txtPrTo = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrPrTo");
TextBox txtGrossAmt = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrGrossAmt");
DropDownList ddlTDS = (DropDownList)gvLLDetails.FooterRow.FindControl("ddlftrTDS");
TextBox txtNetAmt = (TextBox)gvLLDetails.FooterRow.FindControl("txtftrNetAmt");
string ConnectionString = ConfigurationManager.ConnectionStrings["Connection"].ConnectionString;
SqlConnection conn = new SqlConnection(ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand("INSERT INTO LandlordDetails(ATMID,SUBCODE,LLName,AggType,PrFrom,PrTo,GrossAmt,TDS,NetAmt)"+
"VALUES ('"+txtATMID.Text+"','"+txtsubcode.Text+"','"+txtLLName.Text+"','"+ddlAggType.SelectedValue+"','"+txtPrFrom.Text+"','"+txtPrTo.Text+
"','"+txtGrossAmt.Text+"','"+ddlTDS.Text+"','"+txtNetAmt.Text+"')",conn);
int result = cmd.ExecuteNonQuery();
conn.Close();
if (result == 1)
{
BindLandlordDetails();
lblResult.ForeColor = Color.Green;
lblResult.Text = "LandLord Details Inserted Successfully";
}
else
{
lblResult.ForeColor = Color.Red;
lblResult.Text = "Details not Inserted Successfully";
}
}
推荐答案
在插入查询之前，将您的公式应用于txtNetAmt，如： -
Before insert query apply your formula on txtNetAmt like:-
txtNetAmt.Text=txtGrossAmt.Text - txtGrossAmt.Text * ddlTDS.SelectedValue
等...
etc...
将公式放入sql查询并绑定gridview。
put formula in sql query and bind the gridview.
