为什么C1TrueDbgrid会有这个错误


private void InitializeComponent()
{
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(GZID));
this.panel1 = new System.Windows.Forms.Panel();
this.textBox3 = new System.Windows.Forms.TextBox();
this.label3 = new System.Windows.Forms.Label();
this.label2 = new System.Windows.Forms.Label();
this.textBox2 = new System.Windows.Forms.TextBox();
this.label1 = new System.Windows.Forms.Label();
this.button = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.panel2 = new System.Windows.Forms.Panel();
this.GZAdviceIDGrid = new C1.Win.C1TrueDBGrid.C1TrueDBGrid();
this.panel3 = new System.Windows.Forms.Panel();
this.TotalCost = new System.Windows.Forms.TextBox();
this.label8 = new System.Windows.Forms.Label();
this.button1 = new System.Windows.Forms.Button();
this.AdviceID4 = new System.Windows.Forms.TextBox();
this.label7 = new System.Windows.Forms.Label();
this.AdviceID3 = new System.Windows.Forms.TextBox();
this.label6 = new System.Windows.Forms.Label();
this.AdviceID2 = new System.Windows.Forms.TextBox();
this.label5 = new System.Windows.Forms.Label();
this.AdviceID1 = new System.Windows.Forms.TextBox();
this.label4 = new System.Windows.Forms.Label();
this.button2 = new System.Windows.Forms.Button();
this.panel4 = new System.Windows.Forms.Panel();
this.tabControl1 = new System.Windows.Forms.TabControl();
this.tabPage1 = new System.Windows.Forms.TabPage();
this.GZAdviceItemGrid = new C1.Win.C1TrueDBGrid.C1TrueDBGrid();
this.tabPage2 = new System.Windows.Forms.TabPage();
this.panel5 = new System.Windows.Forms.Panel();
this.GZAItemManageGrid = new C1.Win.C1TrueDBGrid.C1TrueDBGrid();//这里报错，不知为什么？

白白天
this.panel6 = new System.Windows.Forms.Panel();
this.btnBatchDelte = new System.Windows.Forms.Button();
this.button6 = new System.Windows.Forms.Button();
this.groupBox2 = new System.Windows.Forms.GroupBox();
this.button5 = new System.Windows.Forms.Button();
this.textBox5 = new System.Windows.Forms.TextBox();
this.groupBox1 = new System.Windows.Forms.GroupBox();
this.radioButton2 = new System.Windows.Forms.RadioButton();
this.radioButton1 = new System.Windows.Forms.RadioButton();
this.button3 = new System.Windows.Forms.Button();
this.UpdateButton = new System.Windows.Forms.Button();
this.label9 = new System.Windows.Forms.Label();
....
}以上是窗口初始化的部分代码。

白天还好，晚上几个有C1TureDbgrid都出现这个问题，也就是因为这个问题我
重装了系统xp和2003.net,以及C1TrueDbgrid 控件集，但没好多久又这样了，
为什么？

[yumanqing]

肯定是C1TrueDbgrid 的引用问题

[哈哈007哈]

此异常说明，对象没有初始化就开始使用它，再去跟踪一下

[Jackie]

对象没有初始化就开始使用它

[shoushii]

对象没有初始化就开始使用它

[liujiwe79]

你里面肯定有一个对象为空了，比如你要设置button1.Enabled = false;如果button1此时为null就会报这个错误

[ufoteam]

C1TrueDBGrid这个对象没有实例化

[impeller]

断点跟踪下

[mada1978]

只要把dbgrid去掉就行．不只c1trueDBgrid是怎么了，代码里有new()呀？

[ganchunsaixx]

我现在也遇到这个问题咯！
