Not able to set value in rad numeric text box

[Esther Nirmala]

Hi,

    I am using Rad numeric text box in my page. Am trying to set the value of numeric text box on seleting a drop down list. But its not displaying the data. And i tried to set the value in prerender of text box also.. that is also not working . How to set the value of rad numeric text box in code behind. If i assign directly to value property its working.. If am assigning from viewstate its not working.

Here is the code i tried:

protected void dropDownListResource_SelectedIndexChanged(object sender, EventArgs e)

        {

double DailyRateToUse = val; //val - viewstate variable
 radNumericTextboxRate.Value = Convert.ToDouble(DailyRateToUse);

        }

    protected void radNumericTextboxRate_PreRender(object sender, EventArgs e)

        {

double DailyRateToUse = val; //val - viewstate variabledouble
radNumericTextboxRate.Value = Convert.ToDouble(DailyRateToUse);

  

}

Thanks
Esther

Hello Esther,

I tried the same scenario and it worked as expected on my end. Here is the sample code that I tried to access RadNumericTextBox in SelectedIndexChanged event of the DropDownList.

C#:

protected void drop_SelectedIndexChanged1(object sender, EventArgs e)
{
        DropDownList list = sender as DropDownList;
        GridDataItem item = (GridDataItem )list.NamingContainer;
        RadNumericTextBox txt = (RadNumericTextBox)item.FindControl("RadNumericTextBox1");
        double DailyRateToUse = 123;
        txt.Value = Convert.ToDouble(DailyRateToUse);
}

Thanks,
Princy.

Hello,

RadNumericTextBox txt = (RadNumericTextBox)item.FindControl("RadNumericTextBox1");

if(!string.IsNullorEmpty(ViewState["Test"]))

{

try

{

    txt.Text = Convert.ToDouble(ViewState["Test"].ToString());

}

Catch

{

 // invalid Text in View State

}
else
{
 txt.Text = Convert.ToDouble("0");
}



}
