Checkbox in datgridview not refrashing page when checked

I am trying to follow this exemple https://www.aspsnippets.com/Articles/Transfer-Selected-Rows-from-one-GridView-to-Another-in-Asp.net.aspx however my version dose not refreash the page when a checkbox is checked why is that?
Here is my front end code,
<asp:GridView ID="gvPurchases" runat="server" AutoGenerateColumns="false" ShowFooter="true" onrowdatabound="gvPurchases_RowDataBound"
ShowHeaderWhenEmpty="true" AllowPaging="True" OnPageIndexChanging="gridView_PageIndexChanging" DataKeyNames="compras_id"
OnRowCommand="gvPurchases_RowCommand" OnRowEditing="gvPurchases_RowEditing" OnRowCancelingEdit="gvPurchases_RowCancelingEdit"
OnRowUpdating="gvPurchases_RowUpdating" CellPadding="3" AllowUserToResizeColumns="True" PageSize="5" AllowSorting="true" onsorting="gvPurchases_Sorting" GridLines="None" CssClass="mGrid" PagerStyle-CssClass="pgr" AlternatingRowStyle-CssClass="alt">
<PagerSettings Mode="Numeric" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkRow" AutoPostBack="true" EnableViewState="true" runat="server" onclick = "Check_Click(this)" OnCheckedChanged="CheckBox_CheckChanged" />
<%--<asp:CheckBox ID="chkRow" runat="server" />--%>
<asp:ImageButton ImageUrl="~/Images/edit.png" runat="server" CommandName="Edit" ToolTip="Edit" Width="20px" Height="20px"/>
<asp:ImageButton ImageUrl="~/Images/delete.png" runat="server" CommandName="Delete" ToolTip="Delete" Width="20px" Height="20px"/>
</ItemTemplate>
<EditItemTemplate>
<asp:ImageButton ImageUrl="~/Images/save.png" runat="server" CommandName="Update" ToolTip="Update" Width="20px" Height="20px"/>
<asp:ImageButton ImageUrl="~/Images/cancel.png" runat="server" CommandName="Cancel" ToolTip="Cancel" Width="20px" Height="20px"/>
</EditItemTemplate>
<FooterTemplate>
<asp:ImageButton ImageUrl="~/Images/addnew.png" runat="server" CommandName="AddNew" ToolTip="Add New" Width="20px" Height="20px"/>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Compras ID" SortExpression="compras_id">
<ItemTemplate>
<asp:Label DataField="compras_id" ID="lblPurschaseID" CssClass="gridTextbox" Text='<%# Eval("compras_id") %>' runat="server" />
</ItemTemplate>
<%--<EditItemTemplate>
<asp:TextBox CssClass="gridTextbox" ID="txtType" Text='<%# Eval("tipo") %>' runat="server" />
</EditItemTemplate>--%>
<FooterTemplate>
<asp:TextBox CssClass="gridTextbox" ID="txtPurschaseIDFooter" runat="server" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Contract Number" >
<ItemTemplate>
<asp:Label DataField="numero_contrato" ID="lblContractNumber" CssClass="gridTextbox" Text='<%# Eval("numero_contrato") %>' runat="server" />
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownList ID="drGridContractID" Runat="server" AutoPostBack="false" OnSelectedIndexChanged="DropDown_SelectedIndexChanged" />
<%-- <asp:TextBox CssClass="gridTextbox" ID="txtSupplier" Text='<%# Eval("nombre_proveedor") %>' runat="server" />--%>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox CssClass="gridTextbox" ID="txtContractNumberFooter" runat="server" />
</FooterTemplate>
</asp:TemplateField>
And here is my backend:
protected void CheckBox_CheckChanged(object sender, EventArgs e)
{
GetData();
SetData();
BindSecondaryGrid();
}
However the page does not refresh when checkbox is checked why is that?

I had to remove onclick = "Check_Click(this)" to fix the proble the onClick is useless.
Change
<asp:CheckBox ID="chkRow" AutoPostBack="true" EnableViewState="true" runat="server" onclick = "Check_Click(this)" OnCheckedChanged="CheckBox_CheckChanged" />
to
<asp:CheckBox ID="chkRow" AutoPostBack="true" EnableViewState="true" runat="server" OnCheckedChanged="CheckBox_CheckChanged" />

Gridview row editing is not working

can anyone tell me what i am missing why my row editing event is not firing.
I am trying to give edit facility in same grid as well as Add new data.
I am able to add new data (new row) but unable to edit existing row for update.

Nested grid edit doesn't work

I'm stuck on this problem where I have grid within grid where the nested grid is editable. I can't get the edit working. What's complicates things is that the nested grid is inside a modal popup extender.
It works to the point where I click on the edit button. Then the EmptyDataText property kicks in with the message. If I click on it second time the grid opens in edit mode but the update/cancel buttons don't work. The cancel button when click displays the EmptyDataText property.
Another issue is that this nested grid doesn't use a object data source so I'm going to have to all the updating and deleting in the code file. Not sure now to do that either.
I would like some advice as to how to make this corrected. Here is the code:

gvForumDetail.DataBind();
}

ModalPopupExtender1.Show();
var gvForumDetail = (GridView)(gvForum.SelectedRow.FindControl("gvForumDetail"));
gvForumDetail.EditIndex = -1;
gvForumDetail.DataBind();
}

I will try to answer part of your question, updating and deleting the code. you need to take advantage of the "onrowcommand" for the inner gridview (OnRowCommand).

I am getting null when I am using (DropDownList)e.Row.FindControl

Here is my code where it's giving the value of ddl = null:
//event handler to bind the data to the row before rendering the gridview
protected void gridview1_RowDataBound(object sender ,GridViewRowEventArgs e)
{
if ((e.Row.RowType == DataControlRowType.DataRow)&&(e.Row.DataItem!=null))
{
//DropDownList ddlNo = (DropDownList)e.Row.FindControl("ddlNo");
DropDownList ddlNo = (DropDownList)e.Row.FindControl("ddlNo");
if (ddlNo != null)
{
ddlNo.DataSource = Test.GetData();
ddlNo.DataBind();
ddlNo.SelectedValue = gridview1.DataKeys[e.Row.RowIndex].Values[0].ToString();//datakeys are used to retain the value of the no. in edit mode
}
}
}
Here is my aspx code:
<asp:GridView ID="gridview1" runat="server" AutoGenerateColumns="false" AutoGenerateDeleteButton="false" AutoGenerateEditButton="false" ShowFooter="true" EmptyDataText="No data available."

Can anyone provide a relevant solution to this?

you put the ddl no in the footer template but you're only checking for that in the (e.Row.RowType == DataControlRowType.DataRow) Change that to FooterRow and it should find it
change the above line to
if(e.Row.RowType == DataControlRowType.Footer && e.Row.DataItem != null)

<%--DataKeyNames="Environment_ID"--%>
' />
<%--
'>
