Iâm trying to determine if a textbox needs validation based on the value selected in the drop down list.
Aspx:
<asp:DropDownList ID="dp_Marital_status" runat="server">
<asp:ListItem></asp:ListItem>
<asp:ListItem Text="Divorced" Value="divorced"></asp:ListItem>
<asp:ListItem Text="Married" Value="married"></asp:ListItem>
<asp:ListItem Text="Single" Value="single"></asp:ListItem>
<asp:ListItem Text="Unknown" Value="unknown"></asp:ListItem>
<asp:ListItem Text="Widow" Value="widow"></asp:ListItem>
<asp:ListItem Text="Separated" Value="separated"></asp:ListItem>
<asp:ListItem Text="Other" Value="other"></asp:ListItem>
</asp:DropDownList>
<asp:TextBox runat="server" ID="txt_Emp_Name" Width="370px">
</asp:TextBox>
<asp:RequiredFieldValidator ID=valrEmployername runat=server Display=dynamic Text=*
ErrorMessage="Employer name required" Enabled=false
ControlToValidate=txt_Emp_Name >
</asp:RequiredFieldValidator>
Code behind:
protected void employment_type_On_textChanged(object sender, EventArgs e)
{
string strEmploymentType = Convert.ToString(dp_Emp_Type.SelectedValue);
if (strEmploymentType.ToString() = "retired")
{
valrEmployername.enabled = true;
}
}
When I run this I get the error:
CS0131: The left-hand side of an assignment must be a variable, property or indexer
Validation based on dropdown list value
