C#Dategridview动态生成控件checkbox,为啥运行时点击checkbox不能选中？

Posted 2023-04-29

前台代码如下：
<asp:GridView ID="testDatagrid" runat="server" AutoGenerateColumns="False" OnRowDataBound="testDatagrid_RowDataBound" Width="294px" Height="134px">
<Columns>
<asp:CheckBoxField HeaderText="可选" />

<asp:BoundField DataField="ToolName" HeaderText="text" />
<asp:TemplateField HeaderText="数量"></asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="数据的更新" />

后台代码实现如下：
#region GridView绑定动态生成的控件
protected void testDatagrid_RowDataBound(object sender, GridViewRowEventArgs e)


if (e.Row.RowIndex > -1)


CheckBox check = new CheckBox();
check.ID = e.Row.RowIndex.ToString();
check.AutoPostBack = true;
check.CheckedChanged += new EventHandler(check_CheckedChanged);
e.Row.Cells[0].Controls.Add(check);

TextBox text = new TextBox();
text.Width = 15;
text.ID = "txt" + e.Row.RowIndex.ToString();
text.Enabled = false;
e.Row.Cells[2].Controls.Add(text);
HiddenField hidden = new HiddenField();
hidden.Value = da.Tables[0].Rows[e.Row.RowIndex][0].ToString();
hidden.ID = "Hidd" + e.Row.RowIndex.ToString();
e.Row.Cells[2].Controls.Add(hidden);



#endregion
#region 处理checkbox所触发的事件
void check_CheckedChanged(object sender, EventArgs e)

int i = Convert.ToInt32(((CheckBox)sender).ID);
TextBox box = this.testDatagrid.Rows[i].Cells[2].FindControl("txt" + i.ToString()) as TextBox;
box.Enabled = true;

#endregion
#region 将客户所选的数据插入数据库
protected void Button1_Click(object sender, EventArgs e)

for (int i = 0; i < this.testDatagrid.Rows.Count; i++)

CheckBox chB = this.testDatagrid.Rows[i].Cells[0].FindControl(i.ToString()) as CheckBox;
TextBox txB = this.testDatagrid.Rows[i].Cells[2].FindControl("txt" + i.ToString()) as TextBox;
HiddenField hid = this.testDatagrid.Rows[i].Cells[2].FindControl("Hidd" + i.ToString()) as HiddenField;
int ii = -1;
if (chB.Checked)

if (txB.Text != null)

try

//引用 DataBase.dll
ii = new ZHXKDatabase(connStr).RunSQLCommandReturnInt("insert into Relation (ToolsID,TagID,[Desc]) values (" + hid.Value + "," + 12 + "," + int.Parse(txB.Text.Trim()) + ")");

catch (Exception exc)

Response.Write(exc.Message);



if (ii == 1)

Response.Write("OK!");




#endregion 参考技术A 是不是有Datagridview的cell点击事件，看看是否覆盖了。 参考技术B 代码写错了 当然选不中咯

vb6.0动态生成复选框并获取选中的值

比如爱好有多个，所以要动态生成多个checkbox，并且能在点击某个按钮的时候能知道选中了哪些？

在窗体上放一个复选框check1，把Index的值设置为0
动态加载：

Dim i As Integer
Dim num As Integer

num = 10 'Num为你要加载的数
For i = 1 To num - 1
Load Me.Check1(i)
Check1(i).Left = Check1(0).Left + Check1(0).Width * i
Check1(i).Top = Check1(0).Top
Check1(i).Visible = True
Check1(i).Caption = "爱好" & i
Next i 参考技术A 最简单的方法用数组控件
更改为相同的控件名~index属性即是区分
