Not able to access hyperlink column inside gridview from code behind

I want to access the HyperLinkField column of the GridView from code behind but I am unable to do so.
I have the column in my dataset but I am still not able to use it.
My HyperLinkField column is named Status.
Here is what I tried:
UltraWebGrid1.DataSource = ObjPriDsGrid;
UltraWebGrid1.DataBind();
string StrPriStatus = "";
for (int IntPriI = 0; IntPriI < UltraWebGrid1.Rows.Count; IntPriI++)
{
if (UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim() != null)
{
StrPriStatus = UltraWebGrid1.Rows[IntPriI].Cells[6].Text.Trim();
}
else
{
}
if (StrPriStatus == "5")
{
UltraWebGrid1.Rows[IntPriI].Cells[8].Text = ""; // Not getting status column here
}
}
Here is my GridView:
<asp:GridView ID="UltraWebGrid1" ShowHeader="true" runat="server" AutoGenerateColumns="false"
DataKeyNames="mkey" OnRowDataBound="Grid_RowDataBound" Width="98%" Height="30%"

</Columns>
</asp:GridView>

Columns like HyperLinkField and CheckBoxField behave a little differently than BoundField. They don't just simply contain text like BoundField. You have to get the control within the cell. You can get the child controls of the cell using the Controls collection. We know that specifically for a HyperLinkField, the HyperLink will be the first control in the collection.
HyperLink hyp = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];

Can you try it like this
if (StrPriStatus == "5")
{
HyperLink HyperLinkObj = (HyperLink)UltraWebGrid1.Rows[IntPriI].Cells[12].Controls[0];
HyperLinkObj.Text = "";
}

Firing a GridView RowCommand event from a Button inside a Template Field - C#

So I have a GridView (gvSummary) which contains a template field with a button inside (btnOpen). This button's purpose is to open a second GridView (gvDetail) in a modal window based on row information from gvSummary.
The problem I am having is that I can't seem to execute the code in gvSummary_RowCommand by clicking the button btnOpen. I can execute the code from the <asp:ButtonField> but this doesn't open the second GridView.
Here is my code:
<asp:GridView ID="gvSummary" runat="server" DataSourceID="SqlgvSummary" AutoGenerateColumns="false"
OnRowDataBound="gvSummary_RowDataBound" OnRowCommand="gvSummary_RowCommand" CssClass="table table-hover table-bordered" EmptyDataText="No data to display." >
<Columns>
<asp:BoundField DataField="ClientRef" HeaderText="Reference No."/>
<asp:BoundField DataField="InsertedWhen" HeaderText="Transaction Date" DataFormatString="{0:dd-MM-yyyy}" />
<asp:BoundField DataField="Commodity" HeaderText="Commodity" />
<asp:BoundField DataField="StartDate" HeaderText="Settlement Date" DataFormatString="{0:dd-MM-yyyy}" />
<asp:BoundField DataField="EndDate" HeaderText="Delivery Date" DataFormatString="{0:dd-MM-yyyy}" />
<asp:BoundField DataField="Value" HeaderText="Transaction Value" DataFormatString="{0:N2}" />
<asp:BoundField DataField="Fee" HeaderText="Fee" DataFormatString="{0:N2}" />
<asp:BoundField DataField="InsertedBy" HeaderText="Purchased By" />
<asp:ButtonField ButtonType="Button" CommandName="cmdDetail1" HeaderText="View Details" Text="View" ControlStyle-CssClass="openModal"/>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<div>
<asp:Button ID="btnOpen" runat="server" Text="Show Gridview" CssClass="openModal" CommandName="cmdDetail2"/>
<div class="modal" id="idModal">
<div class="container">
<div class="modal-header">
<h1>Transaction Details<a class="close-modal" href="#">×</a></h1>
</div>
<div class="modal-body">
<asp:GridView ID="gvDetail" runat="server" DataSourceID="SqlgvDetail" AutoGenerateColumns="false"
OnRowDataBound="gvDetail_RowDataBound" CssClass="table table-hover table-bordered" EmptyDataText="No data to display." >
<Columns>
<asp:BoundField DataField="metalid" HeaderText="Metal ID"/>
<asp:BoundField DataField="enddate" HeaderText="End Date" DataFormatString="{0:dd-MM-yyyy}" />
<asp:BoundField DataField="startdate" HeaderText="Start Date" DataFormatString="{0:dd-MM-yyyy}" />
<asp:BoundField DataField="clientref" HeaderText="Client Ref" />
<asp:BoundField DataField="quantity" HeaderText="Quantity" DataFormatString="{0:N2}" />
</Columns>
</asp:GridView>
</div>
<div class="modal-footer">
<asp:Button ID="btn_close" runat="server" Text="OK" CssClass="close-modal btn-sm btn-primary"/>
</div>
</div>
</div>
<div class="modal-backdrop"></div>
</div>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Code Behind:
protected void gvSummary_RowCommand(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
string name = e.CommandName.ToString();
string clientRef = gvSummary.Rows[index].Cells[0].Text;
Response.Write("<br> index = " + index);
Response.Write("<br> name = " + name);
Response.Write("<br> clientRef = " + clientRef);
SqlgvDetail.SelectCommand = " SELECT td.metalid , td.enddate , td.startdate , td.clientref , td.quantity " +
" FROM trxdetail td " +
" WHERE td.clientref = " + "'" + clientRef + "'";
}
When I click the <asp:ButtonField>, the SQL is correct and the Response.Write() sets the correct variables in gvSummary_RowCommand. However, the modal window doesn't open.
When I click btnOpen, the modal window opens but does not set the variables in gvSummary_RowCommand.
I can't seem to be able to egt this working so any help is appreciated.
Thanks.

Two Item templates in one Template field?

Is it possible to have two item templates in one template field? This is my current code and its not working because when I run it e.Row.FindControl("gvQuoteItems") always returns null:
ASPX:

<EmptyDataTemplate>
No Data To Display!
</EmptyDataTemplate>
</asp:GridView>
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
Code-behind:
if (e.Row.RowType == DataControlRowType.DataRow)
{
int categoryID = int.Parse(gvQuote2.DataKeys[e.Row.RowIndex].Value.ToString());
if (categoryID == 16)
{
GridView gvQuoteItems = e.Row.FindControl("gvMotorQuoteItems") as GridView;
gvQuoteItems.DataSource = _QuoteBLL._GetMotorQuoteItemsDataTable(quote.QuoteID);
gvQuoteItems.DataBind();
}
else
{
GridView gvQuoteItems = e.Row.FindControl("gvQuoteItems") as GridView;
gvQuoteItems.DataSource = _QuoteBLL._GetQuoteItemsDataTable(quote.QuoteID, categoryID);
gvQuoteItems.DataBind();
}
}
When I try to run the above as it is, e.Row.FindControl("gvQuoteItems") always returns null. But if I remove the second ItemTemplate, it works fine. But you see, one of the rows has different columns (gvMotorQuoteItems). How can I go about this?

You cannot override the same template two times. However you can have two placeholeholders within the template and show/hide only the relevant one via Visible property.
<ItemTemplate>
<asp:PlaceHolder ID="phFirst" runat="server">
... pnlQuoteItems
</asp:PlaceHolder>
<asp:PlaceHolder ID="phSecond" runat="server">
... pnlMotorQuoteItems
</asp:PlaceHolder>
</ItemTemplate>

Please help

Writing an all new answer since the first one was way too verbose.
Set the ShowFooter="true" on your GridView. Next edit the first TemplateField like this:
<asp:TemplateField HeaderText="Select" ItemStyle-Width="5">
<ItemTemplate>
<asp:CheckBox ID="chkDelete" runat="server" onClick="Check_Click(this)" />
</ItemTemplate>
<FooterTemplate>
Number of records: <%# grdTeacherProfile.Rows.Count %>
</FooterTemplate>
</asp:TemplateField>
And that's all you should need. At least works while I tested.
There should also be some way to span the text to several columns, but didn't have time to test for that..

int RowCount = grdTeacherProfile.Rows.Count;
lblDisplayCount.Text = RowCount.ToString();
Try this code.

How to disable LinkButton within GridViewclick from Client Side using JavaScript?

I have a GridView, In one column I have LinkButton control. I want to disable click from client side for certain condition on this column. Means for some rows it will not be possible for User to call onclick event and for some rows it is possible.
I want to achieve this from client side using javascript.
Or When User clicks on link, It will notify the User that this action can't be completed for this row.

In GridViewMultiplePOSAssociationId there is one column "Status" which has label LabelStatusPendingPOSId, LabelStatusPendingPOSId text is set Applied, Not Applied at the time of Binding. For Rows which has Status Applied, User should not be able to click on LinkButton Associate/Replace else He is allowed to click.

use this code OnRowDataBound for Your Grid
protected void grdViewCustomers_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType==DataControlRowType.DataRow)
{
LinkButton LinkbtnPOSId=(LinkButton)e.Row.FindControl("LinkbtnPOSId");
Label LabelStatusPendingPOSId = (Label)e.Row.FindControl("LabelStatusPendingPOSId");
Boolean boolStatus = LabelStatusPendingPOSId.Text == "Applied" ? true : false;
//LinkbtnPOSId.Attributes.Add("onclick", "function CheckStatus('" + boolStatus.ToString() + "')");
LinkbtnPOSId.Enabled = boolStatus;
}
}

Try this..
You can loop through the Gridview and make the particular control disable...
I am writing the code in javascript pageload function...
function PageLoad(sender, args)
{
for (var i = 0; i <= RowCount; i++)
{
document.getElementById('Gridview1_HyperLinkAssociate_' + i.toString() + '').disabled = true;
}
}
Set RowCount as the number of rows of the Gridview...
