Question

<div class="checkboxData">
    <asp:CheckBoxList ID="cblStrength" Class="checkBoxFilter" runat="server" DataTextField="language" OnSelectedIndexChanged="cblStrength_SelectedIndexChanged"
    DataValueField="language" RepeatLayout="OrderedList" Width="432px">  
    </asp:CheckBoxList> 
</div>

以上代码适用于我的Checkboxlist。此Checkboxlist值是从数据库

动态绑定的

DataSet dsFilterItems = new DataSet();

CheckBoxList cblStrength = (CheckBoxList)Master.FindControl("cblStrength");
CheckBoxList cblForm = (CheckBoxList)Master.FindControl("cblForm");
CheckBoxList cblSize = (CheckBoxList)Master.FindControl("cblSize");

dsFilterItems = itemsBL.GetItemsForFilter(null, null, strkeywords, null, null, custRole);

if (dsFilterItems.Tables.Count >= 0)
{

    //cblStrength.Controls.Add(new LiteralControl("<br />"));
    cblStrength.DataSource = dsFilterItems.Tables[0];
    cblStrength.DataTextField = "Strength";
    cblStrength.DataValueField = "Strength";
    cblStrength.DataBind();

    //cblForm.Controls.Add(new LiteralControl("<br />"));
    cblForm.DataSource = dsFilterItems.Tables[1];
    cblForm.DataTextField = "itemForm";
    cblForm.DataValueField = "itemForm";
    cblForm.DataBind();

    //cblSize.Controls.Add(new LiteralControl("<br />"));
    cblSize.DataSource = dsFilterItems.Tables[2];
    cblSize.DataTextField = "CF_Size";
    cblSize.DataValueField = "CF_Size";
    cblSize.DataBind();
}

根据搜索动态加载复选框值...

现在我必须在数据网格中只显示复选框选中的值，我有从数据库中选择的查询，如下所示

SELECT * FROM Items WHERE Strength IN (@cblStrength)

但它仅适用于单个复选框值，我应该如何进行多重选择以及如何在不刷新的情况下加载数据网格。

您必须连接sql查询才能使多个/逗号分隔参数起作用。例如

<FrameLayout>

快乐编码!!

将复选框值绑定到数据库以加载gridTable
