Power bi report is developed based on single table which consists of 10 columns. All the columns is displaying in when clicking on 'See records' context menu option.
Is there any way to hide some columns.
there is a context menu item if you rightclick one of the columns. It hides the column but also for report generation. Not sure, if that does the trick for you but worth a check.
Hope this helps

I am new in Xamarin forms and I need to implement a table in Xamarin forms. Requirement is-
Initially table will be empty and has four columns. After feeling form and clicking on submit button, new entry will be added in table. First column is Test, second column is single radio button, third column is again single radio button and forth column is button to delete that row it self.
I need to know which approach will be suitable to implement this requirement. Is it grid layout or tableview or something else.
Consider Table View use cases vs List View use cases. Table views are meant for static content. You should really consider a list view for dynamic content. (like adding a row with views) Being new to Xamarin.Forms, you should take the time to read completely through the documentation as (at least for me) it wasn't straightforward. Also, consider a WebView as radio buttons are not going to play nicely across platforms, and your problem would be easily solvable with jQuery.
I would like to show my table data in grid. The table has more than 50 columns. By default they are displayed fine but I need a way to hide/show columns which are not required on screen.
So is there any way to achieve this? I think right clicking on the header should show all headers in a list box, allowing selection of which columns we want, then refresh the grid.
Please let me know if Telerik supports this and, if so, how?
No builtin feature available and this is one of many reasons why we are still thinking about other grids instead of telerik.
In the demo site there is a page where they show all the column names with checkboxes on top of the grid and you can check/uncheck to show/hide columns. see that sample source code, is simple to implement but still is custom code to add manually. I love the devexpress grid with customization popup and columns dragdrop from there but nothing like that for us in Telerik :-(
I'm having a QTableWidget with 10,000 records. I need to show only 30 rows at a time and hide the remaining rows. While dragining/clicking vertical scrollbar it should show corresponding rows and hide the other rows.
ie, if one clicks on upper scroll button it should show one more upper item and hide one lower item and vice versa. It should happen while scrolling as well.
Can anyone help me in doing this?
I think you can trap the events of up/down buttons as Nicholas said, for the tracking of slider/scroll bar u need use 'setTracking(true)'followed by the handling of signal either 'valueChanged(int)' or 'sliderMoved(int)'.
Thanks,

Qt unfortunately won't make this easy for you, there is ways and means of doing it however. Depending on how you're populating your widget I'd recommend setting it up so you initially populate your 30 rows, you then need to trap the signals coming from the scroll buttons being clicked and tell the table widget to remove the upper/lower item and add the next one, there's trade off's to this method, but it'll make it easier than trying to maintain a large list of hidden rows.
I don't know if explicitly showing/hiding things is the way you want to go. Instead, take a look at Qt's model and view classes. If you are using a database, have a look at QSqlTableModel, which should handle these things for you. Otherwise, have a look at the Model-View programming document, their related examples, and especially the portion about optimizing for performance (although in a model, 10,000 records isn't really all that many for most uses).
There is a way to change table scrolling from pixels to items. In Designer Property Editor for the table, in the QAbstractItemView section, there is a VerticalScrollMode selection. This can either be ScrollPerPixel or what you probably want, ScrollPerItem.
That may change the behavior of the signal from pixels to items which would make your calculations easier.
I'm using 4.4.3.
I am having some problems with tabbing within my asp.net pages. This project was developed with Visual Studio 2008.
Case 1
I have two html tables. The first table has two rows; the second table has four rows. Within the cells are of each table are asp.net fields, text boxes and radio button lists. I set focus to the first field of table one. I then press the tab key multiple times. The focus moves through the field of table one and then through the fields in the first row of the table two. Then instead of goes to the second row of the table two it return to the table one.
But if I set focus to the last cell on the first row of table two, it tabs through the remaining cells of table two properly. Can you tell me how to get the tabbing to behave properly and go to the cells in there natural order? Note that I am setting the tab index property in the order that I want.
Case 2
On another page I have an html table with a single row followed by a gridview control. The gridview control is writeable and has the following columns: Check Box, Radio Button List, Text Box, Text Box, Text Box and a Check Box List. If I click on one of Check Box, Radio Button List or Check Box List., then press tab, the cursor pops out of the grid and sets focus on the first field of the table outside the grid. But if I set focus on one of the text boxes and tab; then the tab goes through the fields of the grid left to right one row at a time. This later behavior is what I want in both cases. I don’t know why my cursor pops out of the grid when I start with a field other than a text box.
Please help if you can.

funny, you explain in details your case but you didn't explain what it needs to be explained in order to someone can understand you :)
first of all, is table1 located in the first tab and table2 in second tab?
what do you used for tabs: asp.net tab control, jquery ui tabs...?
what do you mean by 'press the tab key multiple times'? same tab? do you have postback on tab click? what is the focus in your case, and so on and on...
cheers
Have you checked the order of the input elements in your HTML? Generally the tab order follows the order of controls.
If that all looks right, then make sure nothing is setting the TabIndex property - as this will also mess up the tab order.
I pretty much resolve this and I wanted to add the answer for anyone who viewed this thread. The problem was the autpostback on certain fields. Once I disabled autopostback, the problems went away.

You need to use Javascript and I referred for your a very good example of navigating through Gridview rows with Up/Down keys.

I have spent a while searching google for an answer to the following question, with no luck.
Does anyone know if there is any way (at all) to use the Design view to edit the contents of an ASP.NET table control (an <asp:Table runat="server">...)?
From all that I can tell, devs are stuck coding their <asp:TableRow>s and <asp:TableCell>s by hand! This is ludicrous, given that you can use the design view as a WYSIWYG editor for standard HTML tables.
In design view go to the properties of your table and select rows and click the button. You can add rows there. Likewise the row properties has a cells property that lets you add cells one at a time.
Still pretty bad but it would cut down on the hand typing.
There is a Rows property you can play with in the design view.
As you add rows to the Rows collection, you have access to the Cell property as well through the dialog presented to you.
