    [CLOSED] ComboBox load value

    Hi all,

    I want to know what is the best way to load the combo from code behind in v.2 .
    In fact, in v.1, I use the following code:

    this.comboBoxCompanies.Value = employee.getCompanyId;
    where employee.getCompanyId is an integer.

    In v.2 , I use the following code:

       this.comboBoxCompanies.SelectedItems.Add(new Ext.Net.ListItem { Value = "" + employee.getCompanyId });
   this.comboBoxCompanies.UpdateSelectedItems();
    The two previous code work good, but I'm wonder if there is a way in v.2 to load data in the same way as in v.1

    Best Regards

    Hi @FpNetWorth,

    Setting .Value in Ext.NET v1 just selects an item, it doesn't load anything.

    It should causes the same effect in Ext.NET v2.

    The requirement is unclear.

    Please provide a working sample for Ext.NET v1. I will try to convert it for Ext.NET v2.

    I would like to list another ways to accomplish it:

    By Index
    comboBoxCompanies.Select(1);
    By Value
    comboBoxCompanies.Select("1");
    By Value
    comboBoxCompanies.SetValue("1");
    By Value
    comboBoxCompanies.SetValueAndFireSelect("1");

    I agree with you Daniil, but i think that he meant select instead of load. Is that correct @FpNetWorth?

    Probably, you are right, Raphael.

    By setting up a ComboBox's Value property appears to be working.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.ComboBox1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { 1, "Item 1" },
                new object[] { 2, "Item 2" },
                new object[] { 3, "Item 3" }
            };
            store.DataBind();
        }
    }

    protected void Select(object sender, DirectEventArgs e)
    {
        this.ComboBox1.Value = 1;
    }
</script>

    Yes, this is what I meant.

    Hi Daniil,

    Thank you for the sample that you provided.

    The problem that I face is that I can't get the value of the selected Item.

    When we click the button "Get", we have the following scenarios:
    1- If the user click "Get" without selecting any value from the combo, we get the selected text instead of the value.
    2- If the user select the same item that was selected on the load, we get the selected text instead of the value.
    3- If the user select a different item than the selected item on load, we get the true value of the selected item.

    Please find below the code:
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
 
<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.ComboBox1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { 1, "Item 1" },
                new object[] { 2, "Item 2" },
                new object[] { 3, "Item 3" }
            };
            store.DataBind();
            this.ComboBox1.Value = 2;
        }
    }
 
    protected void Select(object sender, DirectEventArgs e)
    {
        this.ComboBox1.Value = 1;
    }
    protected void GetValue(object sender, DirectEventArgs e)
    {
        object comboValue = this.ComboBox1.Value;
        string comboVal = this.ComboBox1.SelectedItem.Value;
        object a = ComboBox1.SelectedItems[0].Value;
        
    }
    
</script>
