I have a powershell script in that script i am using datagridview.
My script is working fine. All looks ok to me.
My issue is i want to get the first column value of selected row. To fulfill this i need to add event (cell click/cell content click/cell mouse click). I am not able to figure it out. How to add event.
Can somebody please advise me on this?
$datagridview1_CellMouseClick = [System.Windows.Forms.DataGridViewCellEventHandler]{
write-host $_.RowIndex # This displays the row number selected
write-host $_.ColumnIndex # This displays the column number selected
write-host $datagridview1.Rows[$_.RowIndex].Cells[0].value # This would display the value of the first cell in the selected row
write-host $datagridview1.Rows[$_.RowIndex].Cells[$_.ColumnIndex].value # This would display the value of the cell selected
}
There are plenty of example availble for C# but not found anything for powershell.
Not a stupid question at all, but a little confusing. You say you want the first column value of the selected row, however based on the output you are looking for it seems you are more interested in the selected cell. I am answering with the assumption that the selection of the cell is what you are looking for.
There are many possible events to work with here. The differences between them are subtle so I will leave it to you to see if there is an event that would work better for your purpose. For my answer I will stick with the event you mentioned: CellMouseClick.
I start by creating the function that I want to execute when the click occurs.
function gridClick(){
$rowIndex = $myGrid.CurrentRow.Index
$columnIndex = $myGrid.CurrentCell.ColumnIndex
Write-Host $rowIndex
Write-Host $columnIndex
Write-Host $myGrid.Rows[$rowIndex].Cells[0].value
Write-Host $myGrid.Rows[$rowIndex].Cells[$columnIndex].value}
Please note that you will have to decide how your variables are scoped and how the function will interact with the datagrid. If you are declaring the datagrid at the script level then you should be able to just reference it by name inside the function. This function will do what you said, in the exact order listed in your question. Edit to taste.
You can add the click event, after declaring your datagrid, like this:
$myGrid.Add_CellMouseClick({gridClick})
Note that the name of the function we created is placed within the brackets.
A few important notes:
There are many events to work with. While testing this out I tried the selectionChanged, click, cellclick, cellmouseclick, enterrow, and other events. You may want to check these out for differences in behavior.
The output may be a little unusual in some cases. For example the CellMouseClick event seems to respond to clicks in the header. So if I click on the cell at row index 1 and column index 1 (second row second column) the script will display the contents appropriately. If I then click on the column heading for the first column, the script will write the same results again (which makes sense because the selected index has not changed) which may seem confusing at first glance.
Keep in mind that datagrids allow for multiple selections and I do not know how that might effect the output. That is up to you to figure out.

I want a button from the command line bar to be visible or invisible depending on whether a record has been selected in the lookup field from the main form or not.
If no record has been selected, then the button should be displayed. Otherwise not.
For this problem, I want to use the Power Fx in PowerApps, but I haven't found a command yet, which shows me the content or something like that of the lookup field. Other field data types like text have worked without problems.
With Javascript, I already managed it without problems, but I would like to do it also in PowerFx if that should work.

The records come from the Table Company, where the attribute is Companyname.
Commands where I think they might work:
If([Selected Record];true;false);If(IsBlank([Selected Record]);true;false);If(IsBlankOrError([Selected Record]);true;false);If(IsEmpty([Selected Record]);true;false)
I guess there are 2 scenarios:
The Lookup form control element is a Dropdown with a Selected output property. Then your approach would work like If(IsBlankOrError(DataCardValue1.Selected),true,false)
If your form control element is a ComboBox then you could use If(CountRows(DataCardValue1.SelectedItems)>0,true,false) or the above described IsBlankOrError.
I'm trying to make a script for a game called Hearthstone. The script will be used to press a certain button and play a certain card. The only problem I have is that the cards change position based on how many you have. So I want to know how I could make buttons to choose the amount of cards in my hand.
I've come across the Hotkeys command but it seems to be more of a toggle thing. All the cards are bound from 1-10 and was thinking that I could make it so ^1-^10 represents how many cards I have but I don't know how I could do that.
Oleg's comment was more of my answer than I thought.
setting ^1 to ^1::numCards=1 and so on, I was able to set an if statement to do what I wanted something to do when the variable numCards equated to different things. Such as:
1:
if numCards = 1
{
do thing
}
return
and so on...
While working with Perl and Gtk2, I have to programmatically remove an option from a drop-down (ComboBox). While I'm aware that $combo_box->remove_text ($position) will do the trick in one shot, I need to remove the option based on its name (entered by the user).
I'm unable to find a method that can return the index of an item by its name. Could someone help out?
It's a bit unclear what you mean by "name"; combo box items don't have names. If the combo box is textual, then each item is made up of text, but that text isn't a name. You could have the same string in all items for instance, which would make it very unclear which one you want to delete.
I think you're going to have to implement it youself, by iterating over the combo box's underlying tree model. Then it's up to you if you want to just delete the first match, continue searching to find all of them.
I was wondering if someone could explain to me how I update a list at runtime in Unity?
For example I have a spell book, which has 3 spells in it, when I drag them to my action bar they get re-parented to it, what I'm trying to do is get a list of each child under the actionbar transform,
My problem is where to actually do something like this if I try something like below in the update, it adds whatever's there many times, which I can understand since update runs every frame..
list = actionbarui.GetComponent(UIGrid).GetChildList();
for(var i =0;i < list.size; i++)
{
buttonList.Add(list[i].gameObject);
}
If I add a callback to the buttons so that whenever they're drag and dropped it runs the above code and add thing's additively, as in, if you drag just one "spell" on it will loop through once, which is fine, but as soon as you add another it loops through three times, that is, it already has one it then adds the same one again PLUS the new button that's just been dragged on for a total of 3.
I've tried changing the code to
list = actionbarui.GetComponent(UIGrid).GetChildList();
for each(var child : Transform in list.GetEnumerator())
{
buttonList.Add(child.gameObject);
}
But this simple doesn't add anything, I am unsure how to go about keep the lists update as they are dragged off and on, could anyone please explain how this is achieved?
Please ignore the second "list" code, it's implementing "BetterLists" as apart of NGUI, so doesn't follow standard list methods.
Thank you for reading

That is the expected result here. You are running through the list of children and adding them to your buttonlist, so first time there is only one item to add, then when you add another child there are two items to add, thus resulting in three items.
Either don't have a for loop and do:
buttonList.Add(the_GameObject_that_was_just_added_to_the_bar);
Or clear your buttonList before the for loop:
list = actionbarui.GetComponent(UIGrid).GetChildList();
buttonList.Clear();
for(var i =0;i < list.size; i++)
{
buttonList.Add(list[i].gameObject);
}
Alternatively to Dover8's response, you can first check if the buttonList already contains a reference to the child to be added. If it does, continue. Otherwise add the new child.
However, given the expense of doing the checks, and since you are already looping through the list already, I'd recommend that you follow his suggestion to clear the list before running the loop. It will probably give you the best performance out of these examples.
If there's a reason you can't or shouldn't clear the buttonList, and you still need to run through it, I'd recommend my suggestion. It really depends on which implementation works best for what you are trying to do. The point is that there are several ways to do this, and they have different performance profiles you need to consider.
I have a data-grid and three column in it. one column is type of DataGridViewComboBoxCell, three items are in this grid combo box, now i have to invoke selection index changed event to change value according to combo value change in grid.
also help me to make a new event ....
please help...
thanks
I really can't understand your question.
But maybe these informations can help:
A ComboBoxColumn has always two kinds of controls. A presenting one (in most cases a label) which is individually for each row. And a editing one that will be shared for the whole column. So take a look into this documentation and the IDataGridViewEditingControl Interface.
Maybe these will give you a starting point on how to solve your problem.
In the Load event for the form, you need to get the cell that you want to add the handler to and cast it as a regular combo box. You can then add the event handler on SelectedIndexChanged, but it must be done programmatically, and depending on the language you are using.
