| Public property bound to button outside of class doesn't have the same value as button bound internally when object is instantiated |
Your problem lies in how you are returning/tracking references to the
object.
In your constructor, you set $Grid = this
However, you return a new object as a result of the function:
return {
selectedRows: $Grid.selectedRows,
refresh: $Grid.refresh,
}
That returned object now only holds a reference to the current value of
$Grid.selectedRows
When your refresh method sets $Grid.selectedRows to a new array it breaks
the associated value from the returned object which remains set to the
original array.
Change your refresh from:
$Grid.selectedRows = []
to:
$Grid.selectedRows.length = 0;

| Is there any way to Edit row of bound fields in gridview with custom edit button? |
Everything is possible ;-)
But you have to decide how you want the edit to be done. If you're not
using the built in functionality to enable editing of the field contents,
you need some other kind of editing. One option would be to use a separate
details view beneath/besides the table that can be edited. Place the detail
view in an update panel to avoid reloading the entire page.
You would also need to place the grid view in an update panel to be able to
reload it's content smoothly once the edited changes are saved.

| Gridview always add new row when click button? |
Here is problem #1 with your code:
//extract the TextBox values
TextBox box1 =
(TextBox)Gridview1.Rows[rowindex].Cells[1].FindControl("txtDate");
TextBox box2 =
(TextBox)Gridview1.Rows[rowindex].Cells[2].FindControl("TextBox2");
TextBox box3 =
(TextBox)Gridview1.Rows[rowindex].Cells[3].FindControl("TextBox3");
This logic is flawed and not even necessary, because when you bind the grid
it will iterate through the collection you supply as the DataSource and use
the TemplateFields you defined in the markup to create each row.
The rows are not actually added to the GridView until is bound to a data
source, a DataTable in your case, like this:
Gridview1.DataSource = dt;
Gridview1.DataBind();
Step #1 is to remove the FindControl lines from your AddNewRowToGrid
method.

You need to click once to get the focus, then another time to actually

| Highlighting a row in asp.net gridview on click of template button |
From the code you posted you are nowhere selecting a row. You have to do it
if you want the SelectedRowStyle to be applied.
There are several ways you can select a row :
Using a button/image/link with CommandName="Select"
Handle it manually by setting the grid view SelectedIndex from code behind.
For example in your row command handler gridContractor_RowCommand you can
write :
protected void gridContractor_RowCommand(object sender,
System.Web.UI.WebControls.GridViewCommandEventArgs e)
{
[...]
GridViewRow selectedRow =
(GridViewRow((Button)e.CommandSource).NamingContainer;
int intRowIndex = Convert.ToInt32(selectedRow.RowIndex);
gridContractor.SelectedIndex = intRowIndex
[...]
}

These controls need to be recreated every single time on Load. In short,

You will want to create a List<CheckBox> that you store in Session

| Get Checked rows of a nested Gridview on button click |
What I'd do is add a CommandArgument to Button4's declaration that will
allow me to find the related GridView2.
So, I'd use what you're using elsewhere, id1. Add CommandArgument='<%#
Eval("id1") %>' to your Button4 declaration.
Now, in Button4_Click, you can cast the sender to a Button like so:
var button4 = (Button)sender;
Once you have button4 casted correctly to a Button, you can access the
CommandArgument property.
var id1 = button4.CommandArgument;
Once you have id1, it's as simple as iterating through the parent GridView,
GridView1. Looks like your second column is bound to id1 as well, so you'd
do the following:
GridView foundGridView2;
foreach(GridViewRow gvr in GridView1.Rows)
{
if(gvr.RowType == DataControlRowType.DataRow &&
gvr.Cells[1].Text == id1)

The object used to load into the GridView is gone as soon as the page

Or link the Grid to a DetailsView, which will query the data, as @Wahtever

| How to download a file bound to an gridview |
After much teeth gnashing, I decided to just call the JavaScript function
directly.
here's the javascript:
function DownloadFile(filename) {
// Check to be sure this async postback is actually
// Create an IFRAME.
var iframe = document.createElement("iframe");
// Point the IFRAME to GenerateFile, with the
// desired region as a querystring argument.
iframe.src = "Default2.aspx?fileName=" + filename;
// This makes the IFRAME invisible to the user.
iframe.style.display = "none";
// Add the IFRAME to the page. This will trigger
// a request to GenerateFile now.
document.body.appendChild(iframe);
}

| My GridView control bound to a SqlDataSource does not update |
You must take care of below points:
The GridView & hence the DataSource never allows changing of the
Columns which are specified in DataKeyNames property.
Don't try to update a PrimaryKey column. This will not be allowed. Although
No error will be shown on clicking update, but if you check the values in
Database, changes aren't applied.
Make sure your Update command is not trying to set a NEW value for Primary
key. as a result, complete Update command will be rejected if you even try
to set a Primary Key. i.e. even other Non- Primary key columns will not
be changed. So if Id is a primary Key, below update command will be
rejected if you specify new value for Id:
UpdateCommand="UPDATE Classes SET Id=@Id,Password=@Password,Name=@Name
WHERE Id=@Id"
So in your case, I guess, Id mus

| Directory.GetDirectories in a GridView with Bound Hyperlink |
Your GridView's datasource is a List of string (containing the path of your
folders).
Your bound hyperlink contains an Eval instruction asking to retrieve le
FullName property of every item of your DataSource. Your DataSource being a
List, it could be translated like that :
foreach(string path in files)
{
HyperLink1.NavigateUrl = path.FullName;
}
Now hopefully you're beginning to see the problem : the string class
doesn't have any FullName property.
The solution is to replace the Eval (which is a bad solution anyway, since
it does reflection and isn't very efficient) by :
<%# Container.DataItem %>
Which is a typed variable even that you can cast
so you could even write this :
<%# (string)Container.DataItem %>

| DataGridView not updating when bound BindingList is changed |
I feel your pain, I struggled with the same problem for many hours. It
turns out that you cannot sort a list of custom objects, regardless if it
is SortableBindingList or BindingList.
Try using the BindingListView instead: http://blw.sourceforge.net/
Use the BindingListView as the soruce for your DataGridView. This will
allow you to have a sortable list and it has no problems with updating
after you add or remove items.
Let me know if you need an example solution.

Well, it doesn't work that way. The inner List<T> has no change

Most convenient way to do what you want is adding the item through the

| Angular pagination not updating when bound list changes due to filtering on an input text box |
Because your pagination is a combination of chained filters, Angular has no

You'll also want to adjust your startFrom filter to say (currentPage - 1) *
pageSize, otherwise, you always start at page 2.
Once you get that going, you'll notice that your pagination is not
accurate, because it's still based on destination.length, and not the
filtered sub-set of destinations. For that, you're going to need to move
your filtering logic from your view to your controller like so:
