i wrote textchanged event for combo box but its not working , If any alternative for this pls help me.

When combo box text is changed then i can enable the text boxes other wise put it in disable mode. but THis textchanged event is not fire when text is changed. Is it combox box can fire both the events or not.

<asp:ComboBox ID="cmbBatchno" OnSelectedIndexChanged="cmbBatchno_SelectedIndexChanged" OnTextChanged="cmbBatchno_textchange" ItemInsertLocation="Prepend" runat="server" AutoPostBack="True" DropDownStyle="Simple" AutoCompleteMode="Append">

public void cmbBatchno_SelectedIndexChanged(object sender, EventArgs e)
{

if (ViewState["BatchNo"] != null)
{
DataTable dtBatchNoDtls = (DataTable)ViewState["BatchNo"];
for (int i = 0; i < dtBatchNoDtls.Rows.Count; i++)
{
if (dtBatchNoDtls.Rows[i]["BatchNo"].ToString() == cmbBatchno.Text)
{
txtExpdate.Text = dtBatchNoDtls.Rows[i]["ExpDate"].ToString();
txtMRP.Text = dtBatchNoDtls.Rows[i]["MRP"].ToString();
txtRate.Text = dtBatchNoDtls.Rows[i]["Rate"].ToString();
if (txtExpdate.Text != "")
txtPacks.Focus();
else
txtExpdate.Focus();
break;
}
else
{
txtExpdate.Text = string.Empty;
txtMRP.Text = "";
txtRate.Text = "";
}
}
}
}


// this is method is not fired when text is changed.
public void cmbBatchno_textchange(object sender, EventArgs e)
{
if (ViewState["BatchNo"] != null)
{
DataTable dtBatchNoDtls = (DataTable)ViewState["BatchNo"];
for (int i = 0; i < dtBatchNoDtls.Rows.Count; i++)
{
if (cmbBatchno.Text == dtBatchNoDtls.Rows[i]["BatchNo"].ToString())
{
txtExpdate.Enabled = false;
txtMRP.Enabled = false;
break;
}
else
{
txtExpdate.Enabled = true;
txtMRP.Enabled = true;
txtExpdate.Text = string.Empty;
txtMRP.Text = "";
txtRate.Text = "";
}
}

}

Please update the code as part of your question to make it more relevent

Is your cmbBatchno_SelectedIndexChanged event firing?
MANI 14 21-Oct-13 2:40am    
yes cmbBatchno_selectedIndexChanged is firing. If selected index text is changed in combo box then cmbBatchno_TextChanged event is not fire.
