使用form2中的更改更新form1中的datagridview [英] updating the datagridview in form1 with changes in form2

问题描述

我已经做了一个单一格式的datagridview行单元格，形式1另一种形式，表格2将与form1上选定的数据网格视图数据一起打开。

我正在使用winforms ... c＃

我已经对datagrid视图数据做了一些操作，在操作阶段结束时，form2将被关闭

 注意：我已经完成
  

我想更新form1中的datagridview，我已经在form2中完成了更改，因为我已经这样做了。

形式1：

  private void productGridview_Cellclick（object sender，DataGridViewCellEventArgs e）
 {
 
 if（e.ColumnIndex！= productgridview.Columns [productimage]。 
 
 if（productgridview.SelectedCells.Count == 0）return; 
 
 int selectedrowindex = productgridview.SelectedCells [0] .RowIndex; 
 
 DataGridViewRow selectedRow = productgridview.Rows [selectedrowindex]; 
 if（img is Image）
 {
 using（ProductDescriptionForm pf = new ProductDescriptionForm（））
 {
 
 pf.picture = img; 
 pf.productname = productname; 
 pf.description = desc; 
 pf.productprice = productprices; 
 pf.categoryname = categoryCombobox.Text; 
 pf.productid = productids; 
 pf.ShowDialog（this）; 
} 
} 
} 
  

在form2中：这样做...

  public int productid 
 {
 get {return _prodid; } 
 set {_prodid = value; } 
 
} 
 public Image picture 
 {
 get {return pictureBox1.Image; } 
 set {pictureBox1.Image = value; 
} 
像我这样使用的一些构造函数，然后
  

在datagridview中删除一行，使用下面的代码...它的罚款..

  private void btnProdDelete_Click（object sender，EventArgs e） 
 {
 using（var context = new TsgEclipseEntities（））
 {
 var pd = new product（）{product_Id = productid}; 
 context.products.Attach（pd）; 
 context.DeleteObject（pd）; 
 context.SaveChanges（）; 
 this.Close（）; // form2 close 
} 
 
} 
  

现在我想更新form1中的datagridview我该怎么做.....

可以有任何人有这个想法...

非常感谢....

解决方案

1）写一个接受product_id参数的数据绑定方法获取数据格式1

2）在form2.close之前，初始化form 1类，并通过传递刚刚更新的product_id并打开form1来调用该方法。

I have done for clicking one the datagridview row cell in one form say form 1 another form say form 2 will open along with selected data grid view data on form1..

I am using winforms...c#

i have done some operations on datagrid view data and at the end of the operations stage the form2 will be closed

    NOTE :upto this i have  finished

i want to update the datagridview in form1 with changes i have done in form2

for that i have done like this..

form 1:

     private void productGridview_Cellclick(object sender, DataGridViewCellEventArgs e)
     {

         if (e.ColumnIndex != productgridview.Columns["productimage"].Index) return;

            if (productgridview.SelectedCells.Count == 0) return;

            int selectedrowindex= productgridview.SelectedCells[0].RowIndex;

            DataGridViewRow selectedRow = productgridview.Rows[selectedrowindex];
              if (img is Image)
               {
                   using (ProductDescriptionForm pf = new ProductDescriptionForm())
                   {

                       pf.picture = img;
                       pf.productname = productname;
                       pf.description = desc;
                       pf.productprice = productprices;
                       pf.categoryname = categoryCombobox.Text;
                       pf.productid = productids;
                       pf.ShowDialog(this);
                   }
               }
      }

and in form2 : I have done like this ...

         public int productid
    {
        get { return _prodid; }
        set { _prodid = value; }

    }
    public Image picture
    {
        get { return pictureBox1.Image; } 
        set { pictureBox1.Image = value; }
    }
   like this  some constructors  i have used and then 

i have deleted one row in datagridview by using below code ...its fine..

      private void btnProdDelete_Click(object sender, EventArgs e)
      {
        using(var context = new TsgEclipseEntities())
        {
              var pd = new product(){ product_Id = productid };
              context.products.Attach(pd);
              context.DeleteObject(pd);
              context.SaveChanges();
              this.Close();   // form2 close                   
       }

    }

now i want to update the datagridview in form1 how i have to do that .....

can any one have idea about this ...

many thanks....

解决方案

1) write a databind method that accepts a product_id parameter to get data in form 1
2) Before form2.close, intialize form 1 class, and call the method by passing the product_id you just updated and open form1.
