C# : datagridview value to textbox on form load
You can use this one: private void SetFirstRowSelected() { if (dataGridView1.Rows.Count > 0) { var row = dataGridView1.Rows[0]; textBox1.Text = row.Cells[1].Value.ToString(); //and so on dataGridView1.CurrentCell = row.Cells[0]; //set focus to first cell in first row } } and call it in your Form_Load event. var row = dataGridView1.Rows[0]; means that we are selecting the very first row from grid. row variable is the reference to it just to avoid typing dataGridView1.Rows[0] every time. dataGridView1.CurrentCell = row.Cells[0] means that we are selecting the first cell in first row (it is the cell in "nomar_nasabah" column).

Setting the value of cell in datagridview not working in form load
My guess is that you are using the DataGridView.AutoGenerateColumns functionnality and even if you set the DataSource property, the DatagridView won't create columns until the grid is displayed. It could explain why it's not working in formload (grid is not initialized yet) and it works after (with shown event for example). So it's possible that: you try to access items that do not exist yet (but the code should raise an exception) or you access valid rows or columns, but they are replaced when the grid is displayed the first time or bound again to a data source, and so your code has no effect (probably your case since you do not mention an exception). Using form_shown is maybe a possible workaround, but I recommend you to use the DataGridView.DataBindingComplete event which is

When my form is hidden and reloaded from another form it is not executing the code in the Load event
Your form is not being reloaded. Check the docs: Form.Load Event Occurs before a form is displayed for the first time. Unfortunately, there seems to be no event for when the form is being hidden or shown - except when it's show for the very first time, which will trigger Load and then Shown. There are events for when the form is closing and after it is closed, though. You may want to use those. If the state of the objects related to the form is important for you, you should store those states somewhere you can restore it when the form is recreated.

There is a possibility that your Install variable which you did not show where you declare it, is either empty or not initialized properly.

How to make last row in a dataGridView on a Windows Form to be displayed all the time while still allowing the remaining rows to scroll
The easiest solution would be to create a second DataGridView directly below the first. Then manually populate it with the single row that you want to be displayed every time the first datagrid binds to data. To make it appear totally seamless, don't forget to hide the column headers in the 2nd datagrid: dataGridView2.ColumnHeadersVisible = false; See this answer for more info.

"No row can be added to a DataGridView control that does not have columns. Columns must be added first." when DataGridView used with DataSource
The columns need to be declared as Properties and not just data members. Add {get;set;} to the class members that you want to appear as Columns in the data grid. class ViewItem { public string Name { get;set;} public string Value { get;set;} } ... BindingList<ViewItem> list= new BindingList<ViewItem>(); dataGridView.DataSource = list; ViewItem vi = new ViewItem(){Name = "Foo", Value = "Bar"}; list.Add(vi); /// works!

jQuery and Django form validation re-load and submit event listener
I can't say for sure what is wrong, but I have a feeling it has to do with the done method (because maybe after the a failed run, it doesn't know what to do). You might need to explicitly tell it what to do in case of failure: $('#myForm').on('submit', function(e) { e.preventDefault(); var form = $(this); $.post({ url: 'ajax/saveForm/', data: form.serialize(), success: function(response) { alert('yey!'); }, error: function(response) { form.html(data); } }); }); I also avoided $() the entire document, used $.post and cashed the form object into a variable, but those shouldn't have any actual effect (they're just conventions).

web submission automation: simulate onclick event on a title element to load form
Have you looked into GreaseMonkey? You should be able to use that to extract the hours per week, do the math and populate the total hours field. You could probably do the entire thing. Anything that can be done on the page in JavaScript could be done within GreaseMonkey. EDIT: The code for that site is awful. I especially like the inline call to loadResume() that is made BEFORE the element it writes to (#build-wrap).

VBA fails doing calculation on table columns
unless you're setting the value somewhere else, glNumRows isn't assigned a value in the code you posted, so it has a default value of 0, which means your loop isn't running at all. Give glNumRows a value and you should see some results. Based on your updated question: The variable glNumRows isn't in the scope of your AddNumbersOnOneRow sub. Just as a test, try putting this line before that loop in your AddNumbersOnOneRow sub (I think I have the syntax right, I haven't tested it): glNumRows = UBound(gINTRules.GridData.DataArray, 2) Again, just to reiterate...glNumRows isn't defined in your AddNUmbersOnOneRow sub. You can add it as a parameter or set it in the sub, or maybe even set it as a global variable if you're feeling really adventurous. If you don't want to add my code abov

DataGridView has no columns
I guess (I don't understand why exactly) you try to access Columns that do not exist yet. Try to move these lines of code in DataGridView.DataBindingComplete event FormFields.GridView.Columns[0].Width = (FormFields.GridView.Width / 10) * 6; FormFields.GridView.Columns[1].Width = (FormFields.GridView.Width / 10) * 4;

Conditional calculation based on data in other columns in R
I'm not sure this is the most efficient way to go about this, but we can find the unique rows and then find for each row in the data.frame which of the unique rows it matches. This number is therefore the pattern ID. We have to collapse rows into single string elements though, otherwise R vectorisation gets in the way of what we want. The example below uses the slightly expanded example data: # Visit1 Visit2 Visit3 #1 yes no no #2 yes no yes #3 yes yes yes #4 no yes no #5 yes no yes # Get unique combinations pats <- unique( data1 ) # Colapse each row to a single string element pats <- apply( pats , 1 , paste , collapse = " " ) #do the same to your data and compare with the patterns data1$pattern <- apply( data1 , 1 , functi

Hide columns of a particular row in datagridview?
There is no easy way of hiding only some cells of particular row.

My suggestion is to change your approach.

NOTE: this answer intends to reply the OP's question in the way usually "searching a term in a datasource" is understood, that is, by relying on a query.

Datagridview frozen columns on right side
joe, in c# DataGridView yo can freeze the column in the middle of the table, only on the start of it, just like in excel. It makes sense, because if we freeze the middle column then we don't know how it should react in the sides. will we need two scroll bars for the different sides? from here you can see that it is the c# wanted behavior: When a column is frozen, all the columns to its left (or to its right in right-to-left languages) are frozen as well. The frozen and unfrozen columns form two groups. If column repositioning is enabled by setting the AllowUserToOrderColumns property to true, the user cannot drag a column from one group to the other.

Hiding a column in the dataGridView, then displaying all columns again
foreach (DataGridViewColumn column in dataGridView1.Columns) { column.Visible = true; } With the foreach, you can act directly on the object. In this case, the only benefit is readability really, although it also removes the need for an extra int variable. In general, foreach can be more efficient, because it leaves the implementation up to the individual collection class, which of course knows the most efficient way to enumerate itself. Example: HashSet Note that because the Columns property is a DataGridViewColumnCollection, which implements IEnumerable rather than IEnumerable<DataGridViewColumn> or similar, you must specify the type of your variable. If you say var, you will get object. I believe this is because DataGridView was designed before generics were implemented.

how to load a datagridview with my data from xml
sounds like what you want to do is pull the XML into a Dataset and then feed that DataSet to a Gridview. and it looks like someone has already asked this question on Stack Exchange as well Any way to populate items from xml to Datagridview using c# Addition what you have is a DataSet with multiple DataTables. the DataGridView is only able to display one DataTable at a time. when you code dataGridView1.DataSource = dataSet.Tables[tag]; and put container_1 in for tag you are pulling back the container_1 TABLE of your DataSet. I am suggesting that you look at the MSDN for DataGridView, DataSet, and DataTable to see if this is really going to work for you. maybe also check this out C# DataGridView Tutorial it couldn't hurt.
