数据绑定组合框 [英] Databinding Combobox

问题描述

cboField1.DataBindings.Add("SelectedItem", ds,"Orders2");

我有一个名为Orders2的表，我想将列名绑定到一个组合框.

解决方案

这可能是正确的方法，但是我从来没有使用过相同的方法.

解决方案

您也可以尝试使用这种替代方式将其绑定.

cboField1.DataSource = Orders2 ;
cboField1.DisplayMember = //Name of fields to be displayed.<br>
cboField1.ValueMember = //Name of field to be kept as value.</br>

助手绑定数据的方法可能是这里的想法

 公共 静态  void  BindField(ListControl控件，对象 dataSource，
                         字符串 displayMember， string  valueMember)
{
    control.DataTextField = displayMember;
    control.DataValueField = valueMember;
    control.DataSource = dataSource;
    control.DataBind();
} 

然后，您可以使用以下内容

 BindField(YourComboBoxControl，YourDataSource，" ，" ); 

cboField1.DataBindings.Add("SelectedItem", ds,"Orders2");

I have a table named Orders2 and I want to bind the Column names to a combobox. Is the sample code above the correct way of binding data to a combobox?

解决方案

That could be the right way but I haven''t used the same anytime.

You could also try to bind it using this alternate way.

cboField1.DataSource = Orders2 ;
cboField1.DisplayMember = //Name of fields to be displayed.<br>
cboField1.ValueMember = //Name of field to be kept as value.</br>

A helper method for binding data might be an idea here

public static void BindField(ListControl control, object dataSource,
                         string displayMember, string valueMember )
{
    control.DataTextField       = displayMember;
    control.DataValueField      = valueMember;
    control.DataSource          = dataSource;
    control.DataBind();
}

You can then use as follows

BindField(YourComboBoxControl, YourDataSource, "FieldNameYouWantToDisplayInComboBox", "IdYouWantToStoreInComboBox");
