[CLOSED] Assigning ComboBox Value

Hi
ComboBox1.Value = "some value" works fine when values are hard-coded. When derived from a DataSource assigning the value appears to fail. Please see the following basic Northwind sample.

Code:

---

protected void Page_Load(object sender, EventArgs e)
{
        if (!X.IsAjaxRequest)
        {
            ComboBox1.Value = "5";
        }
}

---

Code:

---

<asp:SqlDataSource
    ID="SqlDataSource1"
    runat="server"
    ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="
    SELECT
        [EmployeeID],
        [LastName]
    FROM [Employees]"
    />


<ext:Store ID="Store1" runat="server" DataSourceID="SqlDataSource1">
    <Model>
        <ext:Model ID="Model1" runat="server" IDProperty="EmployeeID">
            <Fields>
                <ext:ModelField Name="EmployeeID" />
                <ext:ModelField Name="LastName" />
            </Fields>
        </ext:Model>
    </Model>
</ext:Store>


<ext:ComboBox
    ID="ComboBox1"
    runat="server"
    StoreID="Store1"
    DisplayField="LastName"
    ValueField="EmployeeID">
</ext:ComboBox>

Hi,

You should apply an integer value, not a string one.

Code:

---

ComboBox1.Value = 5;

---

because EmployeeID has integer type.

Haha - that's what you get when looking at code when you're too tired. Thanks Daniil (you can close),

Actually there is a problem here ... using the example below if you click the button without making a selection from the combobox you will get an incorrect value (retrieving 'text' rather than 'value'). If you make a selection on the combobox and then click the button it works fine.

Code:

---

protected void Page_Load(object sender, EventArgs e)
{
    if (!X.IsAjaxRequest)
    {
        ComboBox1.Value = 6;
    }
}

protected void Button_Click(object sender, DirectEventArgs e)
{
    X.Msg.Alert("ComboBox1 Value", "Combo Value: " + ComboBox1.SelectedItem.Value).Show();
}

---

Code:

---

<asp:SqlDataSource
    ID="SqlDataSource1"
    runat="server"
    ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="
    SELECT
        [EmployeeID],
        [LastName]
    FROM [Employees]"
    />


<ext:Store ID="Store1" runat="server" DataSourceID="SqlDataSource1">
    <Model>
        <ext:Model ID="Model1" runat="server">
            <Fields>
                <ext:ModelField Name="EmployeeID" />
                <ext:ModelField Name="LastName" />
            </Fields>
        </ext:Model>
    </Model>
</ext:Store>


<ext:ComboBox
    ID="ComboBox1"
    runat="server"
    StoreID="Store1"
    DisplayField="LastName"
    ValueField="EmployeeID">
</ext:ComboBox>


<ext:Button ID="Button1" runat="server" Text="Click Me">
    <DirectEvents>
        <Click OnEvent="Button_Click" />
    </DirectEvents>
</ext:Button>

Confirmed.

Please populate the ComboBox SelectedItems collection instead of setting up its Value.

Example

Code:

---

protected void Page_Load(object sender, EventArgs e)
{
    if (!X.IsAjaxRequest)
    {
        ComboBox1.SelectedItems.Add(new Ext.Net.ListItem()
        {
            CustomConfig =
            {
                new ConfigItem("value", "6", ParameterMode.Raw)
            }
        });
    }
}
