how to set property for a user control from cs file

ansriharsha

Hi , i have created a user control numberbox which is working fine . But i want set the property value from aspx.cs file dynamically which is not possible . it is taking the value from toolboxdata table only even though i set the property in page load. numberbox code:

using System.Collections.Generic;
using System.Text;
using System;
using System.Web.UI;
using System.ComponentModel;
using System.Web.UI.WebControls;
using System.Text.RegularExpressions;

namespace ERP.Controls
{
/// /// Number Box ASP.NET control
///
[
ToolboxData("<{0}:NumBox runat=server>"),
DefaultProperty("DecimalPlaces")
]

public class NumBox : TextBox
{

    private int mDecimalPlaces = 0;
    private char mDecimalSymbol = '.';
    private bool mAllowNegatives = true;

    /// /// Gets or sets the number of decimals for the number box.
    /// 
    \[
    Bindable(true),
    Category("Appearance"),
    DefaultValue(typeof(int), "2"),
    Description("Indicates the number of decimal places to display.")
    \]
    public virtual int DecimalPlaces
    {
        get { return mDecimalPlaces; }
        set { mDecimalPlaces = value; }
    }


    



    /// /// Gets or sets the digit grouping symbol for the number box.
    /// 
    \[
    Bindable(true),
    Category("Appearance"),
    DefaultValue("."),
    Description("The digit grouping symbol.")
    \]

    public virtual char DecimalSymbol
    {
        get { return mDecimalSymbol; }
        set { mDecimalSymbol = value; }
    }

    /// /// Gets or sets wheter negative numbers are allowed in the number box.
    /// 
    \[
    Bindable(true),
    Category("Appearance"),
    DefaultValue(true),
    Description("True when negative values are allowed")
    \]
    public virtual bool AllowNegatives
    {
        get { return mAllowNegatives; }
        set { mAllowNegatives = value; }
    }



    /// /// Gets or sets the value of the number box.
    /// 
    \[
    Bindable(true),
    Category("Appearance"),
    DefaultValue(0),
    Description("Indicates the number of decimal places to display.")
    \]

We don't need to see all of your code, only the relevant bits. Most will just ignore a post with this much code.

I think the value of the DecimalPlaces property is not stored in ViewState. You need to override LoadViewState and SaveViewState methods in the Custom Control.
