protected void Page_Load（ object sender，EventArgs e）

{
Bind_Evaluation（）;
}
}
受保护 void Bind_Evaluation（）
{
gv_Evaluation.DataSource = ViewData [ MonthlyAward];
gv_Evaluation.DataBind（）;
}
受保护 void gv_Evaluation_RowCommand（ object sender，GridViewCommandEventArgs e）
{
try
{
if （e.CommandName == 选择 ）
{
int index = Convert.ToInt32（e.CommandArgument）;
GridViewRow selectedRow = gv_Evaluation.Rows [index];
int id = Convert.ToInt32（gv_Evaluation.DataKeys [index] .Value.ToString（））;
Response.Redirect（ 〜/ Views / Evaluation / Submit_Evaluation.cshtml？index = + id）;
}
Bind_Evaluation（）;
}
catch （例外情况）
{
throw Ex;
}
}

< / ItemTemplate > < / asp：TemplateField >
< < span class =code-leadattribute> asp：buttonfield buttontype = 按钮 commandname = 选择 headertext = text = 评估 / >
< ; /列 >
< / asp：GridView >
解决方案
而不是：
< asp：buttonfield buttontype = 按钮 commandname = 选择 headertext = text = 评估 xmlns：asp = ＃unknown / >
试试这个：
< asp：templatefield >
< itemtemplate < span class =code-keyword>>
< asp：button id = btn runat = server commandname = 选择 < span class =code-attribute> CausesValidation = false AutoPostBack = true text = 评估 > < / asp：button >
< / itemtemplate >
< / asp：templatefield >
--Amit
尝试使用temapte字段并使用锚标记并在内部使用Eval
< asp：TemplateField >
< HeaderTemplate >
< asp：标签 ID = lblIDLoc runat = server < span class =code-keyword>> 位置< / asp：标签 >
< / HeaderTemplate >
< Ite mTemplate >
< a href = 〜/ Views / Evaluation / Submit_Evaluation.cshtml？index = <％ #Eval（ Id）％> > ClickTo Move < / a >
< / ItemTemplate >
< ItemStyle HorizontalAlign = 中心 / >
< / asp：TemplateField >
< asp：GridView ID = grvView runat = server AutoGenerateColumns = false BorderWidth = 0 GridLines = 无 AllowPaging = True宽度= 100％ RowCommand = grvView_RowCommand >
< Columns>
< asp：TemplateField>
< HeaderTemplate>
< asp：按钮ID = grvbtnEdit CommandName = 选择 runat = server Text = 评估 > < / asp：按钮 >
< / HeaderTemplate >
< ItemTemplate>
// 您的代码
< / ItemTemplate >
< / asp：TemplateField >
< / 列 >
< / asp：GridView >
protected void grvView_RowCommand（ object sender，GridViewCommandEventArgs e）
{
if （e.CommandName == 选择）
{
}
}
Hi,
I have gridview and have a button inside gridview.onclick of button i need to navigate to another page.
Row command is not firing
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Bind_Evaluation();
}
}
protected void Bind_Evaluation()
{
gv_Evaluation.DataSource = ViewData["MonthlyAward"];
gv_Evaluation.DataBind();
}
protected void gv_Evaluation_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName == "Select")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = gv_Evaluation.Rows[index];
int id = Convert.ToInt32(gv_Evaluation.DataKeys[index].Value.ToString());
Response.Redirect("~/Views/Evaluation/Submit_Evaluation.cshtml?index=" + id);
}
Bind_Evaluation();
}
catch (Exception Ex)
{
throw Ex;
}
}
<asp:GridView ID="gv_Evaluation" runat="server" EnableModelValidation="True"
AutoGenerateColumns="false" OnRowCommand="gv_Evaluation_RowCommand" DataKeyNames="Int_AssociateId">
<Columns>
<asp:TemplateField HeaderText="Associate Id">
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("Int_AssociateId") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
<asp:TemplateField HeaderText="Associate Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("Var_AssociateName") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
<asp:TemplateField HeaderText="Manager Id">
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("Int_ManagerId") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
<asp:TemplateField HeaderText="Manager Name">
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("Var_ManagerName") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("Var_Status") %>'></asp:Label>
</ItemTemplate></asp:TemplateField>
<asp:buttonfield buttontype="Button" commandname="Select" headertext="" text="Evaluate"/>
</Columns>
</asp:GridView> 解决方案
Instead of:
<asp:buttonfield buttontype="Button" commandname="Select" headertext="" text="Evaluate" xmlns:asp="#unknown" />
Try this:
<asp:templatefield> <itemtemplate> <asp:button id="btn" runat="server" commandname="Select" CausesValidation="false" AutoPostBack="true" text="Evaluate"></asp:button> </itemtemplate> </asp:templatefield>
--Amit
Try to use temapte field and use anchor tag and use Eval inside
<asp:TemplateField> <HeaderTemplate> <asp:Label ID="lblIDLoc" runat="server">Location</asp:Label> </HeaderTemplate> <ItemTemplate> <a href="~/Views/Evaluation/Submit_Evaluation.cshtml?index=<%# Eval("Id") %>">ClickTo Move</a> </ItemTemplate> <ItemStyle HorizontalAlign="Center" /> </asp:TemplateField>
<asp:GridView ID="grvView" runat="server" AutoGenerateColumns="false" BorderWidth="0" GridLines="None" AllowPaging="True" Width="100%" RowCommand="grvView_RowCommand"> <Columns> <asp:TemplateField> <HeaderTemplate> <asp:Button ID="grvbtnEdit" CommandName="Select" runat="server" Text="Evaluate" ></asp:Button> </HeaderTemplate> <ItemTemplate> // YOUR CODE </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>
protected void grvView_RowCommand(object sender, GridViewCommandEventArgs e) { if (e.CommandName == "Select") { } }
