亲爱的所有人，

我有GridView&我将CategoryID与DataKeyNames绑定了.
DataKeyNames =类别ID"

我的GridView中有链接按钮.

当我单击该链接按钮时，我需要获取该行的CategoryID.

我需要为此链接按钮编写哪个事件以及如何执行?

Dear All,

DataKeyNames="CategoryID"

I have link button in my GridView.

When i click that link button i need to get that row CategoryID.

Which event i need to write for this link button & how to do this?

推荐答案

hi，
您可以为链接按钮定义CommandArgument和CommandName，例如:

you can define CommandArgument and CommandName for your link button,For example :

<ItemTemplate>
<asp:LinkButton ID="user" runat="server" CssClass="grid_Link" CommandArgument='<%# Eval("idHuman") %>' CommandName="Edit" Text='<%# Eval("userName") %>'></asp:LinkButton>
</ItemTemplate>

并在gridview的RowCommand事件中获取commandArgument:

and in RowCommand event of gridview get commandArgument :

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName)
        {
            case "Edit":
                {
                    string userName = e.CommandArgument.ToString();
                }
                break;
        }
    }

您需要使用LinkBut​​ton的LinkBut​​ton_Command.只需将LinkBut​​ton的CommandName设置为某些内容(例如"Select")，然后将CategoryId绑定到它的CommandArgument.然后，在LinkBut​​ton_Command上，可以获得单击了LinkBut​​ton的那一行的CategoryId.

希望对您有帮助，
干杯.

Hi,
You need to use LinkButton_Command of your LinkButton. Just set the CommandName of the LinkButton to something(for instance ''Select'') and Bind the CategoryId to it''s CommandArgument. Then, on LinkButton_Command you can get the CategoryId of that row which it''s LinkButton is clicked.

I hope it helps,
Cheers.

在网格视图的行命令"事件中尝试使用此方法

Try this in Row Command event of grid view

int rowindex = Convert.ToInt32(e.CommandArgument);
int MRLID = Convert.ToInt32(gvMRLSearch.DataKeys[rowindex].Value); //gvMRLSearch is gridview name
