How to preserve value of textboxes using TemplateFields in GridView

I have a GridView that lists data from my mysql database table. In addition, I created two TemplateFields to the GridView. The first TemplateField displays the data from database tables and the second TemplateView contains 1x asp:TextBox (a.k.a quantity) and 2x asp:Buttons (a.k.a +/- buttons which change the value inside the quantity TextBox. In addition to binding the GridView on PageLoad event, I also have a search TextBox which filters the rows displayed in the GridView. Here is the code behind for the search GridView TextBox:
private void SearchProducts()
{
string constr = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
using (MySqlCommand cmd = new MySqlCommand())
{
string sql = "SELECT logic_code,description,image_location,product_group,supplier_number,sequence,unit_code,unit_of_price,location,sales_date,price_pref,special_price,in_stock,total_inventory,new_products FROM products";
if (!string.IsNullOrEmpty(txtSearch.Text.Trim()))
{
sql += " WHERE description LIKE " + "'%" + txtSearch.Text + "%'";
}
cmd.CommandText = sql;
cmd.Connection = con;
using (MySqlDataAdapter sda = new MySqlDataAdapter(cmd))
{
DataTable dt = new DataTable();
sda.Fill(dt);
GridView1.DataSource = dt;
dt.Columns.Add(new DataColumn("QUANTITY"));
GridView1.DataBind();
//TextBox qty4 = GridView1.FindControl("qty_ordered") as TextBox;
// for(int i = 0; i < GridView1.Rows.Count; i++)
//{
// Label test222 = (Label)GridView1.Rows[i].FindControl("test2");
// TextBox qty2 = (TextBox)GridView1.Rows[i].FindControl("qty_ordered");
// if (ViewState["purchased"] != null)
// {
// qty2.Text = ViewState["purchased"].ToString();
// }
// //test222.Text = qty2.Text;
//}
}
}
}
//foreach(GridViewRow rows in GridView1.Rows)
{
//Label test22 = rows.FindControl("test2") as Label;
//TextBox qty = rows.FindControl("qty_ordered") as TextBox;
//if (ViewState["purchased"] != null)
//{
//qty.Text = ViewState["purchased"].ToString();
//}
}
}
First I tried saving each Rows TextBox.Text to ViewState but wasn't successful, then I tried dynamically adding a new column to DataTable before DataBind() but that also went south... The Buttons (+/-) and TextBox work fine when PostBack is from the buttons themselves. However, as soon as I filter the GridView using the c# code above, The TextBoxes all turn back to "0" and lose their values. I think that adding the new column dynamically is the way to go, I'm just not sure how to save/update the values without creating EditTemplateFields.
Here is my asp.net code for the GridView:
<asp:GridView id="GridView1" EnableViewState="true" AutoGenerateColumns="false" PageSize="100" ShowHeader="false" DataKeyNames="logic_code" AllowPaging="true" runat="server" Style="width:100%;margin-top:45px;">

<asp:Label id="test2" runat="server" Visible="true" Enabled="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Here is the code behind for how I populate the GridView on PageLoad when the GridView is not getting filtered by the search box:
private void BindGrid()
{
string constr = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
con.Open();
using (MySqlCommand cmd = new MySqlCommand("SELECT logic_code,description,image_location,product_group,supplier_number,sequence,unit_code,unit_of_price,location,sales_date,price_pref,special_price,in_stock,total_inventory,new_products FROM products"))
{
using (MySqlDataAdapter da = new MySqlDataAdapter())
{
cmd.Connection = con;
da.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
da.Fill(dt);
GridView1.DataSource = dt;
dt.Columns.Add(new DataColumn("QUANTITY", System.Type.GetType("System.Double")));
GridView1.DataBind();
con.Close();
}
}
}
}
}
And PageLoad is here:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
BindGrid();
}
if (string.IsNullOrEmpty(txtSearch.Text))
{
//txtSearch.Attributes.Add("CssStyle", "cursor");
txtSearch.Attributes.Add("placeholder", " Showing All Products");
}
//foreach(GridViewRow row in GridView1.Rows)
//{
// if (IsPostBack)
// {
// if (ViewState["purchased"].ToString() != null)
// {
// qty.Text = ViewState["purchased"].ToString();
// }
// }
//}
}
I also have EnableViewState = "true" at the top of page.
***Note: with the code below on each button (+/-), the ViewState seems to save fine as my labels get populated appropriately by reading the ViewState even when postback. However, the values of the labels (ViewState value) get reset once I call the private void SearchProducts()
for(int i = 0; i < GridView1.Rows.Count; i++)
{
Label test222 = (Label)GridView1.Rows[i].FindControl("test2");
TextBox qty2 = (TextBox)GridView1.Rows[i].FindControl("qty_ordered");
ViewState["purchased"] = qty2.Text;
test222.Text = ViewState["purchased"].ToString();
}
and heres 2 snapshots: (as you can see, when I enter "Benus" inside the search textbox, the gridview gets filtered correctly, but all the TextBox values gets reset to "0")

Bulk Edit Update Multiple Rows in ASP.Net GridView using CheckBoxes

you can see VT_AClReport Table design In the below HTML Markup I have a simple ASP.Net GridView with 3 columns.
First column containing the CheckBox, second column containing a Label for display ID and Access Path of the folder respectively and the third column containing a Label and DropDownList for display and edit status of the folder respectively.
Here I am using GridView with paging to display the data, and the data is about millions of rows. When I click on submit button to update the checkbox selected rows, execution time is taking too much to update the rows in table.
For Example: for 5000 rows = 26 min.
Can anyone help me to resolve this issue and reduce the execution time to update all the records within few seconds.

Stored Procedure
ALTER PROCEDURE [dbo].[VT_ACLReportChangeStatus]
(
#ChangeStatus nvarchar(50)=null,
#ACLId int
)
AS
// Exec VT_ACLReportChangeStatus 'Complete',34
BEGIN
UPDATE VT_ACLReport SET Status = #ChangeStatus WHERE ACLId = #ACLId
End

Replace the UPDATE statement in your stored procedure with T-SQL given below.
I am assuming ACLId is the primary key with a clustered index and you have an index on Status column. You would be better off if you create another index on ACLId and include column Status in it since that will really speed up the lookup in UPDATE statement.
In this T-SQL, updates are happening in batches of 1000 records rather than updating the whole data set. You can play around with changing the value of 100 to something like 500 or even less to come up with the best update batch.
DECLARE #numberOfRowsUpdated INT = 1000, #maxRowsToUpdate INT = 1000;
BEGIN TRY
BEGIN TRAN
WHILE (#numberOfRowsUpdated > 0)
BEGIN
UPDATE TOP (#maxRowsToUpdate) VT_ACLReport SET Status = #ChangeStatus
WHERE ACLId = #ACLId and Status <> #ChangeStatus;
SET #numberOfRowsUpdated = ##ROWCOUNT;
END
if ##trancount > 0
COMMIT TRAN
END TRY
BEGIN CATCH
if ##trancount > 0
ROLLBACK TRAN
-- log and raise error
END CATCH

I solved this problem by maintaining View State, Preserving all checked checkbox state and storing in view state.
then concatenating all the id's in one variable.

GridView gv = (GridView)sender;

Reordering Columns in a Gridview Dynamically

I have a gridview I'm trying to reorder the columns for, but I'm getting an object not found error.
The code works when I don't include the code under "//code to move columns", but when I include that code, I get an object not found error that "s += txtAD.Text.Trim();" object reference is not set to an instance. It's weird because no matter which columns I switch, it always throws the error that it can't find column 1.
Any ideas?

Save state of checkbox in gridview when changed to edite mode

When I am clicking on imagebutton in my gridview, some cells become editable
but, it loses all the checkboxs values that in the gridview.
Is there a way to save these values?
I made a function who gets the checkboxes values from my xml but, when I call the function inside the command era it's not working.
When I call that function in other imagebutton command era in the gridview which doesn't make some cells editable, that works and the function runs and the values from the xml shown on the checkboxes.
Thanks

GridView_RowUpdating not firing

I have Gridview with ItemTemplate and EditItemTemplate:
But when i click "Ok" button, nothing happens. I tried to put trace point on RowUpdating event and click "Ok" button, but its not even triggered. I assume, that problem could be in the same "Id" of ItemTemplate and EditItemTemplate lbl_first_fl. But earlier this worked fine, the only thing was changed - i updated Visual studio to 2015 and changed Windows to 8. So i installed VS 2013, but problem still occures. Any suggestions? Or maybe how can i deal with it using different id's?

You name the event on the grid like this?
<asp:GridView ID="TaskGridView" runat="server"
AutoGenerateEditButton="True"
AllowPaging="true"
OnRowEditing="TaskGridView_RowEditing"
OnRowCancelingEdit="TaskGridView_RowCancelingEdit"
OnRowUpdating="TaskGridView_RowUpdating"
OnPageIndexChanging="TaskGridView_PageIndexChanging">
</asp:GridView>
