c# - 如何检查 radComboboxItem 'CheckBox' ？

Question

我对库“Telerik”有一点疑问。事实上，我想用'checkBox'实现'RadCombobox'。它运作良好，但当我想要'检查'一个项目，这不可能？!这是我的示例代码。我更改了属性“selected”的属性，但不幸的是，它没有选中“checked”框......

非常感谢您的回答!

//Define the sqlAdaptater for binding source

System.Data.SqlClient.SqlDataAdapter myBinding = new SqlDataAdapter("SELECT [name] FROM [dbo].[tblProcess] WHERE [currentVersion] = 1 AND [deleted] = 0 AND [parent] = 0",connectionString);

DataTable links = new DataTable();

myBinding.Fill(links);

//Set the attributs of RadCombobBox

RadComboBoxSelectedEntity.DataTextField = "name";
RadComboBoxSelectedEntity.DataValueField = "name";
RadComboBoxSelectedEntity.DataSource = links;

//Not working..its selected but not checked ?
RadComboBoxSelectedEntity.SelectedIndex = 1;

//Not exist ?? -> 
RadComboBoxSelectedEntity.CheckedIndex = 1;

首先尝试调用方法DataBind

RadComboBoxSelectedEntity.DataBind();

在调用 DataBind 之后，您可以尝试这行代码仍然无法正常工作，

RadComboBoxSelectedEntity.Items[1].Checked = true;
