如何在gridview中获取e.rowindex [英] How to get e.rowindex in gridview

问题描述

e.RowIndex在Gridview_RowEditing不可用



我尝试过：



string index = e.RowIndex

解决方案

参考这个简单的例子：



< pre lang =c＃> protected void Page_Load（ object sender，EventArgs e）
{
if （Page.IsPostBack） return < /跨度>;
DataTable dt = new DataTable（）;
dt.Columns.Add（ IDInventory）;
dt.Columns.Add（ IDSubCat）;
dt.Rows.Add（ 1 ， ABC）;
dt.Rows.Add（ 2 ， XYZ）;
grd.DataSource = dt;
grd.DataBind（）;
}



受保护 void grd_RowDeleting（ object sender，GridViewDeleteEventArgs e）
{
int index = e .RowIndex;
}

< asp：GridView runat =serverID =grdAutoGenerateColumns =falseOnRowDeleting =grd_RowDeleting>

< Columns>

< asp：TemplateField HeaderText =ID>

< ItemTemplate>

< asp：Label ID =lblIDrunat =serverText ='<％＃Eval （IDInventory）％>'/>

< / ItemTemplate>

< / asp：TemplateField>



< asp：TemplateField HeaderText =Category>

< ItemTemplate>

< asp：Label ID =lblCatrunat = serverText ='<％＃Eval（IDSubCat）％>'/>

< / ItemTemplate>

< / asp：TemplateField> ;



< asp：TemplateField HeaderText =>

< ItemTemplate>

< asp：LinkBut​​ton ID =LinkBut​​ton1CommandName =Deleterunat =server>

删除< / asp：LinkBut​​ton>

< / ItemTemplate>

< / asp：TemplateField>

< / Columns>

< / asp ：GridView的>

e.RowIndex is not avaliable at Gridview_RowEditing

What I have tried:

string index= e.RowIndex

解决方案

refer this simple example:

protected void Page_Load(object sender, EventArgs e)
       {
           if (Page.IsPostBack) return;
           DataTable dt = new DataTable();
           dt.Columns.Add("IDInventory");
           dt.Columns.Add("IDSubCat");
           dt.Rows.Add(1, "abc");
           dt.Rows.Add(2, "xyz");
           grd.DataSource = dt;
           grd.DataBind();
       }



       protected void grd_RowDeleting(object sender, GridViewDeleteEventArgs e)
       {
           int index = e.RowIndex;
       }

<asp:GridView runat="server" ID="grd" AutoGenerateColumns="false" OnRowDeleting="grd_RowDeleting">
<Columns>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%#Eval("IDInventory") %>' />
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField HeaderText="Category">
<ItemTemplate>
<asp:Label ID="lblCat" runat="server" Text='<%#Eval("IDSubCat") %>' />
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" CommandName="Delete" runat="server">
Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
