推荐答案

可以实现如下:

Aspx中的网格将如下所示:

Hi,
This Can Be Attained As Follows :

The Grid in Aspx Will Be Something Like This :

<asp:GridView ID="gvwDemo" runat="server" Width="100%" AutoGenerateColumns="False"

    OnRowDataBound="gvwDemo_RowDataBound">
    <Columns>
        <asp:TemplateField HeaderText="**">
            <ItemTemplate>
                <asp:ImageButton ID="imgSave" runat="server" Visible="false" ImageUrl="~/Images/save.gif"

                    CommandName="Save" ToolTip="Save" CommandArgument='<%# Bind("PrimaryKeyID")%>'>
                </asp:ImageButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="**">
            <ItemTemplate>
                <asp:ImageButton ID="imgEdit" runat="server" ImageUrl="~/Images/edit.gif" CommandName="Edit"

                    ToolTip="Edit" CommandArgument='<%# Bind("GMDocGroupID")%>'></asp:ImageButton>
                <asp:ImageButton ID="imgCancel" Visible="false" runat="server" ImageUrl="~/Images/cancel.gif"

                    CommandName="Cancel" ToolTip="Cancel" CommandArgument='<%# Bind("PrimaryKeyID")%>'>
                </asp:ImageButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="**">
            <ItemTemplate>
                <asp:ImageButton ID="imgDelete" runat="server" ImageUrl="~/Images/delete.gif" CommandName="Delete"

                    ToolTip="Delete" CommandArgument='<%# Eval("PrimaryKeyID")%>' OnClientClick="return confirm('Are you sure that you want to delete this record?');">
                </asp:ImageButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField HeaderText="">
            <ItemTemplate>
                Your Controls Here
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

在Cs文件中编写此代码:


public void gvwDemo_RowDataBound(object sender，GridViewRowEventArgs e)
{

如果(e.Row.RowType == DataControlRowType.DataRow&& gvwDemo.EditIndex == 0)
{
ImageButton imgSave =(ImageButton)e.Row.FindControl("imgSave");
如果(imgSave！= null)
{
imgSave.Visible = true;
gvwDemo.Columns [0] .Visible = true;
}
ImageButton imgDelete =(ImageButton)e.Row.FindControl("imgDelete");
如果(imgDelete！= null)
{
imgDelete.Visible = true;
gvwDemo.Columns [2] .Visible = true;
}

}
其他
{
ImageButton imgEdit =(ImageButton)e.Row.FindControl("imgEdit");
如果(imgEdit！= null)
{
imgEdit.Visible = true;
}
ImageButton imgDelete =(ImageButton)e.Row.FindControl("imgDelete");
如果(imgDelete！= null)
{
imgDelete.Visible = true;
gvwDemo.Columns [2] .Visible = true;
}
ImageButton imgSave =(ImageButton)e.Row.FindControl("imgSave");
如果(imgSave！= null)
{
imgSave.Visible = false;
gvwDemo.Columns [0] .Visible = false;
}
}
if(e.Row.RowType == DataControlRowType.DataRow&& gvwDemo.EditIndex> = 0)
{
ImageButton imgEdit =(ImageButton)e.Row.FindControl("imgEdit");
imgEdit.Visible = false;

ImageButton imgCancel =(ImageButton)e.Row.FindControl("imgCancel");
imgCancel.Visible = true;

ImageButton imgSave =(ImageButton)e.Row.FindControl("imgSave");
如果(imgEdit！= null)
{
imgSave.Visible = true;
gvwDemo.Columns [0] .Visible = true;
}

ImageButton imgDelete =(ImageButton)e.Row.FindControl("imgDelete");
如果(imgDelete！= null)
{
imgDelete.Visible = false;
gvwDemo.Columns [2] .Visible = false;
}
}
}

Write This Code in Cs File:


public void gvwDemo_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowType == DataControlRowType.DataRow && gvwDemo.EditIndex == 0)
{
ImageButton imgSave = (ImageButton)e.Row.FindControl("imgSave");
if (imgSave != null)
{
imgSave.Visible = true;
gvwDemo.Columns[0].Visible = true;
}
ImageButton imgDelete = (ImageButton)e.Row.FindControl("imgDelete");
if (imgDelete != null)
{
imgDelete.Visible = true;
gvwDemo.Columns[2].Visible = true;
}

}
else
{
ImageButton imgEdit = (ImageButton)e.Row.FindControl("imgEdit");
if (imgEdit != null)
{
imgEdit.Visible = true;
}
ImageButton imgDelete = (ImageButton)e.Row.FindControl("imgDelete");
if (imgDelete != null)
{
imgDelete.Visible = true;
gvwDemo.Columns[2].Visible = true;
}
ImageButton imgSave = (ImageButton)e.Row.FindControl("imgSave");
if (imgSave != null)
{
imgSave.Visible = false;
gvwDemo.Columns[0].Visible = false;
}
}
if (e.Row.RowType == DataControlRowType.DataRow && gvwDemo.EditIndex >= 0)
{
ImageButton imgEdit = (ImageButton)e.Row.FindControl("imgEdit");
imgEdit.Visible = false;

ImageButton imgCancel = (ImageButton)e.Row.FindControl("imgCancel");
imgCancel.Visible = true;

ImageButton imgSave = (ImageButton)e.Row.FindControl("imgSave");
if (imgEdit != null)
{
imgSave.Visible = true;
gvwDemo.Columns[0].Visible = true;
}

ImageButton imgDelete = (ImageButton)e.Row.FindControl("imgDelete");
if (imgDelete != null)
{
imgDelete.Visible = false;
gvwDemo.Columns[2].Visible = false;
}
}
}
