Telerik RadNumericTextBox not returning updated value which is set from client side javascript

[Himanshu]

i have created a RadNumericTextBox inside a Talerik Rad Grid Edit form template as below:

<pre lang="xml">&lt;telerik:RadNumericTextBox ID=&quot;rdtbTPCCommissionAmount&quot; DataType=&quot;System.Decimal&quot;
                                                EnabledStyle-HorizontalAlign=&quot;Right&quot; Type=&quot;Number&quot; NumberFormat-DecimalDigits=&quot;2&quot;
                                                ReadOnly=&quot;true&quot; AutoPostBack=&quot;false&quot; CssClass=&quot;amountDueWidth disableInputStyle&quot;
                                                runat=&quot;server&quot; NumberFormat-AllowRounding=&quot;true&quot; Style=&quot;width: 100% !important;&quot;
                                                Width=&quot;100%&quot;&gt;
                                                &lt;IncrementSettings InterceptMouseWheel=&quot;false&quot; InterceptArrowKeys=&quot;false&quot; /&gt;
                                            &lt;/telerik:RadNumericTextBox&gt;</pre
On a another RadNumericTextBox blur event i calling a Javascript funtion as below:
<pre lang="xml">function validateThirdPartyCommissionRate(){
               validateThirdPartyRate(&quot;&lt;%= rgThirdPartyCommissions.ClientID %&gt;&quot;);
           }</pre>
From this above funtion i am calling a method written in JS file like below and setting some value to that RadNumericTextBox:

<pre lang="cs">function validateThirdPartyRate(radGridId) {
    var grid = $find(radGridId).get_element();
    var commissionAmt = $telerik.findElement(grid, &quot;rdtbTPCCommissionAmount&quot;);</pre>
<pre lang="cs">var calculatedAmount = parseFloat(rate) * parseFloat(premiumFeeAmt) / 100;
           commissionAmt._setNewValue(calculatedAmount);
           $(&quot;#ctl00_cphMainContentPage_rgThirdPartyCommissions_ctl00_ctl07_rdtbTPCCommissionAmount&quot;).val = calculatedAmount;
           commissionAmt._value = calculatedAmount.toFixed(2);
           commissionAmt._text = calculatedAmount.toFixed(2);
           commissionAmt.value = calculatedAmount
}</pre>

I have used all diffrent property/methods to set the value some of them are setting the value on UI but when i tried to DirectCast this control on serverside it gives me it's old value not the updated which i set from Javascript just like above.

<pre lang="sql">commissionAmt = DirectCast(editedItem.FindControl(&quot;rdtbTPCCommissionAmount&quot;), RadNumericTextBox).Text
</pre>

So suggestion will be welcome to to fix this issue?

Hi Himanshu,

Please try the following approach to access a one RadNumericTextBox from other on its onblur event:

ASPX:

<telerik:GridTemplateColumn HeaderText="Coulmn1">
    <EditItemTemplate>
        <telerik:RadNumericTextBox ID="RadNumericTextBox1" runat="server">
        </telerik:RadNumericTextBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn HeaderText="Coulmn2">
    <EditItemTemplate>
        <telerik:RadNumericTextBox ID="RadNumericTextBox2" runat="server">
        </telerik:RadNumericTextBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = (GridEditableItem)e.Item;
        RadNumericTextBox textbox1 = item.FindControl("RadNumericTextBox1") as RadNumericTextBox;
        RadNumericTextBox textbox2 = item.FindControl("RadNumericTextBox2") as RadNumericTextBox;
        textbox2.Attributes.Add("onBlur", "return Onblur('" + textbox1.ClientID + "','" + textbox2.ClientID + "')");
    }
}

JS:

<script type="text/javascript">
    function Onblur(txt1, txt2) {
        var text1 = $find(txt1);// Access 1st textbox
        var text2 = $find(txt2);//Access 2nd textbox
        var total = text2.get_textBoxValue();
        text1.set_value(total); //set value to 1st textbox
    }
</script>

Thanks,
Princy

Thanks a lot Princy. That's perfectly worked. :) But i don't understand it's weird behaviour in my scenario. Do you have any thoughts on it?

Hi Himanshu,

From your code I'm not sure how you are trying to access the RadNumericTextBox. Setting the RadTextBox value using its set_value() client method should persist it after subsequent submits.

Thanks,
