I am trying to open my nested gridview for a single Parent Row and gets correctly open with one single record of the child row.
The paging of the rows is provided in the main gridview.
My problem is the page change, when I try change page I have this error :
GridView paging event gvProducts_PageIndexChanging not firing
How to do resolve this ?
My code below.
Thanks in advance for any help.

Please try this :
[Solution] The GridView 'GridView1' fired event PageIndexChanging which wasn't handled
I hope I was helpful.
The buttonfield with command EDIT doesn't work until I put
OnRowEditing="grdviewContractorTypes_RowEditing"
Problem:
I wrote this code
<asp:GridView runat="server" ID="grdviewContractorTypes" OnRowEditing="grdviewContractorTypes_RowEditing" OnRowCommand="grdviewContractorTypes_RowCommand" DataKeyNames="pk_ContractorTypes_ContractorTypeID" AutoGenerateColumns="false" CssClass="table table-condensed table-bordered table-striped table-responsive">

<asp:BoundField DataField="ContractorTypeName" HeaderText="Contractor Type" />
<asp:ButtonField CommandName="edit" ImageUrl="~/assets/global/images/shopping/edit.png" ButtonType="Image" ControlStyle-Width="25px" ControlStyle-Height="25px" />
</Columns>
</asp:GridView>
.cs
protected void grdviewContractorTypes_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName == "edit")
{
byte ContractorTypeID = Convert.ToByte(grdviewContractorTypes.DataKeys[Convert.ToInt32(e.CommandArgument)].Value);
//HFActID.Value = ID.ToString();
btnAddContractorType.Visible = false;
btnUpdated.Visible = true;
DataTable dt = MngContractorTypes.SelectContractorTypesByContractorTypeID(ContractorTypeID);
DataRow r = dt.Rows[0];
txtBoxContractorTypeName.Text = r["ContractorTypeName"].ToString();
HdnFieldContractorTypeID.Value = r["pk_ContractorTypes_ContractorTypeID"].ToString();
//txtSearch.Text = "Testing...";
//Response.Write("DONE");
}
}
catch (Exception ex)
{
Response.Write(Convert.ToString(ex.Message));
}
}
The above code runs when I click button field with 'edit' command in DEBUGGER but doesn't do anything in actual, on screen until I put this.

{
}

When I first get to my page I check some checkboxes and then press F5. Apparently after pressing it I dont have any values in SelectediIndexes and all unselected checkboxes must be checked = false on the PreRender stage but they appear checked after all this. And the problem of the same nature: I checked some on the first page; went to the second page (currently having 2 indexes in the SelectedValues) and after pressing F5 the same I have checked the same checkboxes as on the first page, though they mustn't. I'm absolutely confused with this. How can I fix this? Thanx for any help.
I've found the reason to that strange behavior. I'm using Firrefox. And one of the features of this browser is saving state of some fields when refreshing the page. If you want to refresh a page fully you should refresh it with pressed shift button. Tested in Google Chrome - works just fine.
I already spend 2 days trying to solve this issue but no luck on how to solve this. I have a GridView to display data from the database then it also have functionality to modify and delete. This is the current ASP code for my GridView:

The problem is I can't update a certain record after click the Update Button, please see the image below:
When I'm in debug mode, it does not pass on OnRowUpdating event instead it passes to OnRowEditing. One thing that it makes me surprise is that when it fires to OnRowCommand, the CommandName set to "Edit" when Update Button is clicked. Please see the image below:

While I have not figured out the bug, there is a workaround you may want to try.
Since the autogenerated edit button is giving you trouble, why not generate it yourself?
Like this:
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:LinkButton ID="lnkedit" runat="server" CommandName="Edit">Edit</asp:LinkButton>
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="lnkedit" runat="server" CommandName="Update">Update</asp:LinkButton>
<asp:LinkButton ID="lnkedit" runat="server" CommandName="Cancel">Cancel</asp:LinkButton>
</EditItemTemplate>
</asp:TemplateField>
And handle it in your code behind:
void dgvSortKey_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="Update")
{
}
}
