gridview中dropdownlist与textbox联动的问题
我想实现的效果是，将ddladjustreason选为清零时，txtadjustreason的enable改为false，请问在
ddladjustreason_TextChanged里应该怎么取到txtadjustreason？
<asp:TemplateField HeaderText="调整原因" >
<ItemStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:DropDownList ID="ddladjustreason" runat="server" OnTextChanged="ddladjustreason_TextChanged" AutoPostBack="True">
<asp:ListItem Value="0">其他</asp:ListItem>
<asp:ListItem Value="1">清零</asp:ListItem>
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="调整原因说明">
<EditItemTemplate>
<asp:TextBox ID="txtadjustreason" runat="server" Text="" Width="50px"></asp:TextBox></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
protected void ddladjustreason_TextChanged(object sender, EventArgs e)
{
if ( ddladjustreason.SelectedItem.Value == "1")
{
txtadjustreason-xxxxx.enable= false;//要取到txtadjustreason，还要判断是第几行的txtadjustreason
}
}
[解决办法]
DropDownList ddladjustreason = (DropDownList)sender;
GridViewRow gvr = (GridViewRow)ddladjustreason.NamingContainer;
TextBox txtadjustreaon = (TextBox)gvr.FindControl("txtadjustreaon");
if (ddladjustreason.SelectedItem.Value == "1")
{
txtadjustreaon.Enabled = false;
}
