问题描述
我有一个带有几个文本框和一个Grid-view的表单.有一个名为"Inward Number"的文本框,其文本更改事件始终触发.当我要触发另一个控件的事件时,它仅触发内向号"文本框的文本更改事件.所有其他控件都会发生这种情况.有人可以帮忙吗?
I have a form with a few text-boxes and a Grid-view. There is this one text-box called "Inward Number", whose text-changed event fires all the time. When i want to fire another control's event, it simply fires the text-changed event of the Inward Number text-box. This happens with all of the other controls. Can someone please help?
protected void txtInward_No_TextChanged(object sender, EventArgs e)
{
a = 'A';
NewRow();
}
我使用了正确的名称,但是仍然会发生此错误.
I have used the correct names, but still this error occurs.
<asp:TextBox ID="txtInward_No" runat="server" Width="220px" CssClass="txtbox"
EnableViewState="False"
AutoPostBack="True" ontextchanged="txtInward_No_TextChanged">
</asp:TextBox>
新行只会在网格中创建新行.
new row just makes a new row in my grid.
private void NewRow(){int rowIndex = 0;
private void NewRow() { int rowIndex = 0;
if (ViewState["CurrentTable"] != null)
{
DataTable dtnew = new DataTable();
dtnew = (DataTable)ViewState["CurrentTable"];
DataRow drr = null;
if (dtnew.Rows.Count > 0)
{
for (int i = 1; i <= dtnew.Rows.Count; i++)
{
TextBox box1 = (TextBox)GridView1.Rows[rowIndex].Cells[2].FindControl("TextBox1");
TextBox box2 = (TextBox)GridView1.Rows[rowIndex].Cells[3].FindControl("TextBox2");
TextBox box3 = (TextBox)GridView1.Rows[rowIndex].Cells[4].FindControl("TextBox3");
TextBox box4 = (TextBox)GridView1.Rows[rowIndex].Cells[5].FindControl("TextBox4");
TextBox box5 = (TextBox)GridView1.Rows[rowIndex].Cells[6].FindControl("TextBox5");
drr = dtnew.NewRow();
if (txtInward_No.Text =="1")
{
drr["InwardNumber"] = txtInward_No.Text + b.ToString();
}
else
{
drr["InwardNumber"] = txtInward_No.Text + a.ToString();
}
drr["Bags"] = box1.Text;
drr["GrossWt"] = box2.Text;
drr["TareWt"] = box3.Text;
drr["NetWt"] = box4.Text;
drr["DCBillWt"] = box5.Text;
rowIndex++;
}
dtnew.Rows.Add(drr);
ViewState["CurrentTable"] = dtnew;
GridView1.DataSource = dtnew;
GridView1.DataBind();
}
}
PrevData();
b++;
a++;
}
