In my Website, I currently use a grid view which generates data from 3 tables namely status, Project_glance, Application_header. SQL Query returns 4 columns but in my grid-view i only shows 3 columns. The last column returns the Status_id of the project.The following is my .aspx code:

ASP.NET

<asp:GridView ID="grdProf" runat="server" AllowPaging="True" AutoGenerateColumns="false" OnPageIndexChanging="grdProf_PageIndexChanging">
 <Columns>
    <asp:TemplateField>
        <ItemTemplate>
           <asp:HyperLink ID="hlnkView" Visible="true" Text="View" runat="server" >   </asp:HyperLink>
        </ItemTemplate>
    </asp:TemplateField>
    <asp:BoundField DataField="ApplicationID" HeaderText="ApplicantionID" />
    <asp:BoundField DataField="PRGLProjectTitle" HeaderText="Project Title" />
    <asp:BoundField DataField="Status" HeaderText="Project Status" />
 </Columns>
</asp:GridView>

If the Status_id > 15 then only view hyperlink will visible otherwise the View hyperlink text will be 'Edit' and a navigate URL will add to this hyperlink and another hyperlink 'Delete' will show to allow user to delete the project.

Please help me to find the correct solution for this..

Hi you can use following code to show hide Hyperlink in gridview according to your condition.

add DataKeyNames to your GridView

XML

<asp:GridView DataKeyNames="Status_id" ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:HyperLink ID="hlnkView" Visible="true" Text="View" runat="server">   </asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

add following code to gridview RowDataBound event

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            int StatusID = Convert.ToInt16(GridView1.DataKeys[e.Row.RowIndex].Values["Status_id"].ToString());
            e.Row.FindControl("hlnkView").Visible = (StatusID > 15) ? false : true;
        }

Thanks,
Imdadhusen

this might not be the best solution but in case you didn't find any other you can use this one use 2 gridviews and in the datasource in the selectcommand in one of them put the condion status_id>15 in the other put status_id<=15

you try like this..

change page design like this..

ASP.NET

<ItemTemplate>
     <asp:HyperLink ID="hlnkView" Visible="true" Text="View" runat="server" ></asp:HyperLink>
     <br />
        <asp:HyperLink ID="hlnkDelete" Visible="false" Text="Delete" runat="server"></asp:HyperLink>
 </ItemTemplate>

C#

//On GridView DataBound Event add the below code..

GridViewRow grdrow = e.Row;
HyperLink lnk = (HyperLink)grdrow.FindControl("hlnkView");
int statusID = Convert.ToInt32(grdrow[grdrow.RowIndex][3].ToString();
if !(statusID > 15)
{
    lnk.Text="Edit";
    lnk.NavigateUrl = "Your Edit URL";
    HyperLink lnk = (HyperLink)grdrow.FindControl("hlnkDelete");
    lnk.Visible=True;
}

hope it works..

Solution 4

C#

you can use iif(coniditionhere, result if true, result if false)
<asp:hyperlink id="hlnkView" visible="<%#iif(Eval("StatusID")>15,"true","false")%>" text="View" xmlns:asp="#unknown"> </asp:hyperlink>
