将CSS添加到listview中的选定链接按钮 [英] Add CSS to selected link button inside listview

问题描述

您好，



我有一个asp.net webform应用程序，在listview中有一个链接按钮。

我想要什么做的是突出显示/更改Itemcommand上所选按钮的颜色。

我尝试了很多解决方案而没有运气。它会改变颜色，但当我点击另一个按钮时它不会改变。



任何帮助都会非常感激。

谢谢

Samira



我的尝试：



我试图在ItemCommand，ItemDataBound和按钮点击上更改所选/点击按钮的颜色。

listview内的链接按钮：

< ; asp：ListView runat =serverID =subs_viewDataSourceID =SubsFilterSqlDataSourceOnItemCommand =subs_view_ItemCommandOnItemDataBound =subs_view_ItemDataBound> 
< ItemTemplate> 
< asp：LinkBut​​ton cssClass =col-md-9 link-btnrunat =serverID =btnSubsCommandName =subsCommandArgument ='<％＃Eval（code）％ >'Text ='<％＃Eval（SubCat_CountItems）％>'OnClick =btnSubs_Click> < / ASP：LinkBut​​ton的> 
< / ItemTemplate> 
< / asp：ListView> 

我尝试以不同方式更改颜色：

 protected void subs_view_ItemCommand（object sender，ListViewCommandEventArgs e）
 {
 if（e.CommandName ==subs）
 {
 
 LinkBut​​ton linkbtn =（LinkBut​​ton）e。 Item.FindControl（ btnSubs）; 
 linkbtn.ForeColor = System.Drawing.Color.Red; 
 //点击另一个按钮时颜色保持红色
} 
} 

 protected void btnSubs_Click（object sender，EventArgs e）
 {
 //subs_view.DataBind（）; 
 // LinkBut​​ton mybtn =（LinkBut​​ton）发送者; 
 ////mybtn.ForeColor = System.Drawing.Color.Black; 
 //mybtn.ForeColor = System.Drawing.Color.Red; 
} 

-

 protected void subs_view_ItemDataBound（object sender，ListViewItemEventArgs e）
 {
 // LinkBut​​ton btnSubs =（LinkBut​​ton）e.Item.FindControl（btnSubs）; 
 //btnSubs.ForeColor = System.Drawing.Color.Black; 
} 

解决方案

您可以尝试设置

 ViewStateMode =已禁用。在按钮点击，回发的情况下，原始颜色将使用默认颜色而不是ViewState中保存的颜色进行恢复。

Hello,

I have an asp.net webform application that has a link button inside a listview.
What I want to do is to highlight/change color of the selected button on Itemcommand.
I have tried a lot of solutions with no luck. It changes the color but it doesn't change back when i click another button.

Any help will be so much appreciated.
Thanks
Samira

What I have tried:

I tried to change color of the selected/clicked button on ItemCommand , ItemDataBound and button click.
Link button inside listview:

<asp:ListView runat="server" ID="subs_view" DataSourceID="SubsFilterSqlDataSource" OnItemCommand="subs_view_ItemCommand" OnItemDataBound= "subs_view_ItemDataBound">
 <ItemTemplate>                                                       
    <asp:LinkButton  cssClass="col-md-9 link-btn" runat="server" ID="btnSubs" CommandName="subs" CommandArgument='<%#Eval("code") %>' Text='<%#Eval("SubCat_CountItems") %>' OnClick="btnSubs_Click"> </asp:LinkButton>
 </ItemTemplate>
</asp:ListView>

I tried to change colors in different ways:

protected void subs_view_ItemCommand(object sender, ListViewCommandEventArgs e)
        {   
            if (e.CommandName == "subs")
            {
                
                LinkButton linkbtn = (LinkButton)e.Item.FindControl("btnSubs");                
                linkbtn.ForeColor = System.Drawing.Color.Red;
//the color stays red when clicking another button
            }
        }

protected void btnSubs_Click(object sender, EventArgs e)
        {
            //subs_view.DataBind();
            //LinkButton mybtn = (LinkButton)sender;
            ////mybtn.ForeColor = System.Drawing.Color.Black;
            //mybtn.ForeColor = System.Drawing.Color.Red;
        }

--

protected void subs_view_ItemDataBound(object sender, ListViewItemEventArgs e)
        {
            //LinkButton btnSubs = (LinkButton)e.Item.FindControl("btnSubs");
            //btnSubs.ForeColor = System.Drawing.Color.Black;
        }

解决方案

You can try to set the

ViewStateMode="Disabled"

on the ListView control. That case on button click, post back happen, the original color will be restored using the default color instead of the color saved in ViewState.
