    Make the controls read only


    How to make all the controls read only in the page.

    I have the request to make all the controls in an asp 2.0 read only, without the code change.

    How can i achieve this in UI or any scripts.

    If you dont want others to change the values of controls in UI then simply make the readonly property of control to true.

    <html xmlns="" >
    <title>Read only</title>
    <form runat="server" id="Form1">
    <asp:textbox ID="Textbox1" runat="server" ReadOnly="true" ></asp:textbox>
    <asp:textbox ID="Textbox2" runat="server" ReadOnly="true"></asp:textbox>
    <asp:Button ID="Button1" runat="server" Text="Button" Enabled="false" />

    Can you elaborate what do you mean by "without the code change." ?

    Do you want to make all control readonly on any action or by default you want those controls to be read only.

    Above answer is correct if you want controls to be readonly by default when page loads


    Happy Coding

    If you make all controls readonly, then what is the use?
    Do the control values are already set. If so then you can change the property of control in design or in script. make readonly="true".

    Like for textbox <asp:textbox ID="txtName" runat="server"
    ReadOnly="true" ></asp:textbox>

    By above setting you can just see the value of textbox which is already set, you can't modify as its readonly.

    Hello Dinesh,

    Should i know why you want to make ReadOnly to your all controls. If you are keeping ReadOnly to your controls than there will be no use of controls. It's just like they will become label. You can just see the value, can not change.

    You can do it by setting the property ReadOnly = true

    e.g :
    <asp:TextBox ID="ReadOnlyTextBox" runat="server" ReadOnly="True"></asp:TextBox>

    Hope this will help you.

    You can do like below to keep the controls readonly.

    Protected void Page_Load(object sender, EventArgs e)
    ControlsReadonly (Page.Controls);

    public void ControlsReadonly(ControlCollection ctrls)
    foreach (Control ctrl in ctrls)
    if (ctrl is TextBox)
    ((TextBox)ctrl).ReadOnly = true;
    else if (ctrl is DropDownList)
    ((DropDownList)ctrl). ReadOnly = true;
    else if (ctrl is Label)
    ((Label)ctrl). ReadOnly = true;
    ControlsReadonly (ctrl.Controls);

    hope this will helpful to you...
