[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:

Code:

this.comboBoxCompanies.Value = employee.getCompanyId;

where employee.getCompanyId is an integer.

In v.2 , I use the following code:

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

Code:

comboBoxCompanies.Select(1);

By Value

Code:

comboBoxCompanies.Select("1");

By Value

Code:

comboBoxCompanies.SetValue("1");

By Value

Code:

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

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(); } } protected void Select(object sender, DirectEventArgs e) { this.ComboBox1.Value = 1; } </script> <!DOCTYPE html> <html> <head runat="server"> <title>Ext.NET v2 Example</title> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:ComboBox ID="ComboBox1" runat="server" DisplayField="text" ValueField="value"> <Store> <ext:Store runat="server"> <Model> <ext:Model runat="server"> <Fields> <ext:ModelField Name="value" Type="Int" /> <ext:ModelField Name="text" /> </Fields> </ext:Model> </Model> <Reader> <ext:ArrayReader /> </Reader> </ext:Store> </Store> </ext:ComboBox> <ext:Button runat="server" Text="Select" OnDirectClick="Select" /> </form> </body> </html>

Thank you @RCN.
Yes, this is what I meant.
Thank you for the clarification.

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:

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> <!DOCTYPE html> <html> <head id="Head1" runat="server"> <title>Ext.NET v2 Example</title> </head> <body> <form id="Form1" runat="server"> <ext:ResourceManager ID="ResourceManager1" runat="server" /> <ext:ComboBox ID="ComboBox1" runat="server" DisplayField="text" ValueField="value"> <Store> <ext:Store ID="Store1" runat="server"> <Model> <ext:Model ID="Model1" runat="server"> <Fields> <ext:ModelField Name="value" Type="Int" /> <ext:ModelField Name="text" /> </Fields> </ext:Model> </Model> <Reader> <ext:ArrayReader /> </Reader> </ext:Store> </Store> </ext:ComboBox> <ext:Button ID="Button1" runat="server" Text="Select" OnDirectClick="Select" /> <ext:Button ID="Button2" runat="server" Text="Get" OnDirectClick="GetValue" /> </form> </body> </html>

Regards.
