Getting and Setting Values

RadInputManager provides with you the ability of setting/getting values of the TextBox controls either client-side or server-side.

Getting values Client-Side

To be able to get or set values client-side, first you should know how to get the TextBox client-side object. This can be done through the client-side object of the RadInputManager. Here is an example:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function pageLoad()
        {
            var inputManager = $find("<%= RadInputManager1.ClientID %>");
            var input = inputManager.get_targetInput("<%= TextBox1.ClientID %>");
        }
    </script>
</telerik:RadCodeBlock>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<telerik:RadInputManager RenderMode="Lightweight" ID="RadInputManager1" runat="server">
    <telerik:TextBoxSetting BehaviorID="Behavior1">
        <TargetControls>
            <telerik:TargetInput ControlID="TextBox1" />
        </TargetControls>
    </telerik:TextBoxSetting>
</telerik:RadInputManager>

For getting and setting values on the client, you can use the methods available in the RadInput control client-side API listed below.

Each client-side object exposes properties for getting and setting the value of the control:

 

Property Return Type Description
get_value(), set_value() NumericTextBoxSetting : numberAll other input controls: string Gets or sets the value of the TextBox control.

In addition to the properties listed above which are present in the client-side object for all the RadInputManager target controls, the TextBox controls targeted under DateInputSettinghave the following additional methods:

 

Property Return Type Description
get_selectedDate() Date Gets the value of the control as a Date value.
set_selectedDate() none Sets the value of the control.
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function pageLoad()
        {
            var inputManager = $find("<%= RadInputManager1.ClientID %>");
            var input = inputManager.get_targetInput("<%= TextBox1.ClientID %>");
            input.set_value("Setting Value Client Side");
        }
    </script>
</telerik:RadCodeBlock>

Getting values Server-Side

On the Server-side, you can operate with the TextBox value directly through the instance of the TextBox control. Use the Text property the TextBox to set/get its value.

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<telerik:RadInputManager RenderMode="Lightweight" ID="RadInputManager1" runat="server">
    <telerik:TextBoxSetting BehaviorID="Behavior1">
        <TargetControls>
            <telerik:TargetInput ControlID="TextBox1" />
        </TargetControls>
    </telerik:TextBoxSetting>
</telerik:RadInputManager>
protected void Page_Load(object sender, EventArgs e)
{
    TextBox1.Text = "Setting Value Server-Side";
}
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    TextBox1.Text = "Setting Value Server-Side"
End Sub

Validation

You can use ASP.NET validators for validating TextBox controls targeted in the RadInputManager settings. In this case validation works the same way as for regular TextBox controls. You simple have to set the ID of the TextBox control as the value of the ControlToValidate property of the validator.

Using different Culture

With the RadInputManager you can specify different Culture per RadInputManager setting. And this Culture usually is different from the current Page Culture. However when setting values, the value you assign to the TextBox control should correspond to the current Page Culture. You should mind this rule especially when entering dates and floating point numbers.
