Question

在我的页面中，我使用List绑定GridView。我的页面上有不同的字段，并将这些字段值存储到列表中并将其与Grid绑定。

它运行良好，但现在我想使用gridview中的复选框更新Gridview，点击复选框，该行中的关联值出现在不同的字段上，并且按钮保存点击gridview应该更新。

不确定如何去做。

我的代码示例如下：

aspx

<table class="tblPopUp">
    <tr>
        <td>
            <asp:Label ID="lblCaste" CssClass="Label" runat="server" Text="Caste"></asp:Label>
        </td>
        <td>
            <asp:DropDownList ID="ddlCaste" runat="server" CssClass="Dropdownlist myddlinPopUp"></asp:DropDownList>
        </td>
    </tr>
    <tr>
        <td>
            <asp:Label ID="lblNo_OfPosition" CssClass="Label" runat="server" Text="No Of Position"></asp:Label>
        </td>
        <td>
            <asp:TextBox ID="txtNoOfPositioninPopUp" runat="server" CssClass="TextBox mytextboxinPopUp"></asp:TextBox>
        </td>
    </tr>
    <tr>
        <td>
            <asp:Label ID="lblMinAge" CssClass="Label" runat="server" Text="Min Age"></asp:Label>
        </td>
        <td>
            <asp:TextBox ID="txtMinAge" runat="server" CssClass="TextBox mytextboxinPopUp"></asp:TextBox>
        </td>
    </tr>
    <tr>
        <td>
            <asp:Label ID="lblMaxAge" CssClass="Label" runat="server" Text="Max Age"></asp:Label>
        </td>
        <td>
            <asp:TextBox ID="txtMaxAge" runat="server" CssClass="TextBox mytextboxinPopUp"></asp:TextBox>
        </td>
    </tr>
    <tr>                    
        <td>
            <asp:Button ID="btnSaveInPopUpReservation" runat="server" CssClass="button" Text="Save" OnClick="btnSaveInPopUpReservation_Click" />
        </td>
    </tr>
</table>

试试此代码

foreach (GridViewRow row in yourGridViewID.Rows)

{
    CheckBox check = (CheckBox)row.FindControl("CheckBoxName");

    if (check.Checked)
    {
        //Button Event Here
    }
    else
    {
        //Else Part..!
    }
}

将列表绑定到GridView并更新GridView
