        CELLSPACING =2的风格=保证金左：58px;的margin-top：13px的＆GT;
          ＆LT; RowStyle的BackColor =＃FFF7E7前景色=＃8C4510/＆GT;

                      ＆LT; ASP：复选框ID =CheckBox1=服务器/＆GT;
                  ＆LT; / EditItemTemplate中＆GT;
                  ＆LT;＆ItemTemplate中GT;
                      ＆LT; ASP：复选框ID =CheckBox1=服务器/＆GT;

codebehind

 保护无效的button1_Click（对象发件人，EventArgs的发送）
    {
        字符串valueForDB = DatabaseList.SelectedValue;
        数据OBJ =新的Data（）;
        如果（valueForDB ==virtualworkplace）
        {
            obj.getDocforVirtualwrkspace（valueForDB）;
            GridView1.DataSource = obj.getDocforVirtualwrkspace（valueForDB）;
            GridView1.DataBind（）;
        }
什么写在这里？
 保护无效Delete_Click（对象发件人，EventArgs的发送）
    {
        }
 

解决方案

试试这个

 私人无效DeleteRows（）
 {
        的foreach（在gridView1.Rows GridViewRow行）
        {
            HtmlInputCheckBox CHK =（HtmlInputCheckBox）row.Cells [0] .FindControl（selectedrowchk）;
            如果（CHK = NULL＆放大器;！＆安培; chk.Checked）
            {
                字符串ID = gridView1.DataKeys [row.RowIndex] .Value.ToString（）; //获得此行的记录的ID
                deleteRecord（ID）;
            }
        }        // RefreshGrid（）;
    }
 

这code是假设你设置在GridView的DataKeyNames属性来存储每个记录的主键。它还假设你把复选框，在第一列

I have a Gridview.I placed checkbox on each row.By selecting the checkbox and clicking on delete button i should get all the selected row of that gridview in the codebehind.Please do help me...

<asp:GridView ID="GridView1" runat="server" BackColor="#DEBA84" 
        BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px" CellPadding="3" 
        CellSpacing="2" style="margin-left: 58px; margin-top: 13px" >
          <RowStyle BackColor="#FFF7E7" ForeColor="#8C4510" />
          <Columns>
              <asp:TemplateField>
                  <EditItemTemplate>
                      <asp:CheckBox ID="CheckBox1" runat="server" />
                  </EditItemTemplate>
                  <ItemTemplate>
                      <asp:CheckBox ID="CheckBox1" runat="server" />
                  </ItemTemplate>
              </asp:TemplateField>
          </Columns>

    </asp:GridView>
    <asp:Button ID="Delete" runat="server" Text="Button"  runat="server" 
        onclick="Delete_Click" />

codebehind

protected void Button1_Click(object sender, EventArgs e)
    {
        string valueForDB = DatabaseList.SelectedValue;
        Data obj = new Data();
        if (valueForDB == "virtualworkplace")
        {
            obj.getDocforVirtualwrkspace(valueForDB);
            GridView1.DataSource = obj.getDocforVirtualwrkspace(valueForDB);
            GridView1.DataBind();
        }
What to write here???
 protected void Delete_Click(object sender, EventArgs e)
    {
        }

解决方案

Try this

 private void DeleteRows()
 {
        foreach (GridViewRow row in gridView1.Rows)
        {
            HtmlInputCheckBox chk = (HtmlInputCheckBox) row.Cells[0].FindControl("selectedrowchk");
            if (chk != null && chk.Checked)
            {
                string id = gridView1.DataKeys[row.RowIndex].Value.ToString(); // get the record's ID of this row
                deleteRecord(id);
            }
        }

        //RefreshGrid();
    }

This code is assuming you set the DataKeyNames property of the GridView to store the primary key of each record. It is also assuming you are putting the checkbox in the first column
