My Client side code for button
protected void btnInsert_Click(object sender, EventArgs e)

try

int productID, quantity;
string stockType;
DateTime stockDate;
productID = int.Parse(ddlprdctname.SelectedValue);
quantity = int.Parse(txtquantity.Text.Trim());
stockType = ddlstocktype.SelectedValue.ToString().Trim();
stockDate = DateTime.Parse(txtstockdate.Text.Trim());
ProductStock prdctstock = new ProductStock();
prdctstock.ProductID = productID;
prdctstock.Quantity = quantity;
prdctstock.StockType = stockType;
prdctstock.StockDate = stockDate;
if (new InsertAction().InsertData(prdctstock))
{
lblmsg.Text = "Inserted Sucessfully";
ViewPanel.Visible = true;
}
else
{
lblmsg.Text = "Please Check all the fields";
}
BindGridView();
ProductInfo prdctinfo = new ProductInfo();
if (stockType == "In")
{
prdctinfo.Quantity += quantity;
}
if (stockType == "Out")
{
prdctinfo.Quantity -= quantity;
}
}
catch (Exception ex)
{
if (ex is FormatException)
{
lblmsg.Text = "Character value are not allowed";
}
else
{
lblmsg.Text = ex.Message;
}
}
}

Put the breakpoint somewhere where it hits. Look at the call stack and step over to the point when you find why it is not going to the method you want to trigger.
Can't do much without more information.
Hope this helps

I saw few unwanted code's
1) please remove the ValidationGroup="vg1" in your all asp.net controls except button .
2) Don't use panel , some time the button click not working on using panel control, so please use table instead of panel .(or remove the asp:panel control )
3) and must check the button click event same as server side .
4) If you give me our server side code then i will response you !!

Use the NeedDataSource event to provide a datasource. My best guess is that it no longer has a datasource after a postback: https://demos.telerik.com/aspnet-ajax/grid/examples/data-binding/simple-vs-advanced/defaultcs.aspx. You will see how often you need to provide datasource when you do it manually.
Similar problems can arise if you disable viewstate too.

lblamount.Text = total.ToString();
}
Here i had given "Showfooter"=true property but still it's not displaying
But while debug value(sumofamount) is assign to label.text

this line apply css for the gridview infooter:
<FooterStyle CssClass="hide" />
i think that this can hide the footr of gridview pls check this css...

LinkButton Event does not get called inside Gridview

I have table containing gridview inside an update panel "PanelSearch" whose display property is set to none.
When i first load the page i have added the table in a placeholder which is inside another updatepanel (main panel). I have a search button inside the "PanelSearch" and when user clicks search i am retrieving data from database and binding it to the gridview.
The gridview has linkbutton as templatefield and OnCommand event.
When i click the linkbutton no event gets fired but my page refreshes and table inside "PanelSearch' disappears.
I don't know why.Can anyone please help me?

And my code behind is like this
protected void SelectPatient(object sender, EventArgs e)
{
LinkButton lnkSelect = (LinkButton)sender;
Session["Selected_Patient_Id"] = lnkSelect.CommandArgument;
}

Generate RowCommand Event of GridView and use it like ..
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName == "Select")
{
//write what you want to do
}
}

LinkButton click event doesn't fire because it is replace it's event on page load while you click on it.
You should use IsPostBack on Page_Load to avoid this. I think you are every time DataBind to GridView on page load.
So Ignore this and use code this way. It will be helpful for your problems.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
grid.DataSource = dsGrid;
grid.DataBind();
}
}

ASP.NET: How do "update" a field in the <EditItemTemplate> that has a null value in the database (SQL)

I am using a FormView control. The allows me to update records in the database. However, when a database field is null I can not update the field on the form. It works fine when the field is not a null value. I am not using any code behind (C#) to bind the data or manipulate the data.
I have read that when there is a null value in the database that there is no record in the "dataset". Can anyone show me how to bind a value in the form when there is a null value previously.
Thanks,
J
